The utility model includes a blade body at the front end of the scissors, a first handle and a second handle formed at the rear end of the scissors, one end of the elastic rod is hinged on the second handle, and when the scissors are closed, the other end of the elastic rod abuts against the first handle. The utility model makes the operation and use of the scissors light, labor-saving, smooth and convenient, and effectively ensures the integrity and beauty of the scissors.

Description

Automatically rebounding open scissors

Technical field

The utility model relates to a kind of relative configurations design of scissors, refers to that especially a kind of can the utilization after the scissors closure automatically springs open that device opens two blades and the structure of being convenient to carry out once more shearing manipulation.

Background technology

At present general scissors system with two cut body involutory mutually after, wear pivot with a hinge pin again and constituted in conjunction with institute, the fore-end that wherein is positioned at scissors forms tool blade and involutory blade mutually, supplies the handle of holding operation in the rear end part formation of scissors; When manipulating, user's one hand is held two handles, utilizes the strength of palm and finger to control the unlatching and closure of scissors with two blades, uses allowing scissors carry out shear action.

Wherein, application of force operating habit according to human hands, it is comparatively easy with the closed application of force of two blades of scissors to see through two handles, see through two handles two blades of scissors are opened comparatively difficulty of the application of force, not only manipulate the trouble effort, and after long-time operation is used, occur the situation of the stiff pain of hand easily, this phenomenon of manipulating difficulty inconvenience, the small-sized scissors that holds usefulness is the most obvious for repairing.

Summary of the invention

The purpose of this utility model provides the scissors that a kind of tool automatically springs open device, and enough back stretch after the scissors closure are provided, and allows manipulating of the scissors smooth and easy facility that becomes, and promotes the practical usefulness that scissors automatically springs open device.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

A kind of automatically rebounding open scissors, include the blade that this scissors front end forms the blade position, the position, rear end of scissors forms first handle, second handle, and bullet property Rod one end hinge is on second handle, and the other end of described bullet Rod leans first handle when scissors is closed.

The utility model uses aforesaid tool to automatically spring open the scissors of device, its Dan Rod spare system is made of the bending of Jin Shu Xian Rod one, structural strength is quite good, and can provide scissors enough back stretch effectively, allows the operation application of force of elastic force become easily convenient.Dan Rod spare dynamically is incorporated into the set pivot seat of handle can change to swing, can directly fold use during use, allow scissors keep open stand-by state effectively, and obsolete the time, can directly collapse in the rear end of handle, allow scissors keep the minimum volume that folds.The utility model is by manipulating of scissors light laborsaving, the smooth and easy facility that becomes, and effectively guarantees the complete attractive in appearance of scissors.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

The utility model parts comprise: blade 1, wheel pipe 2, Dan Rod 3, support post 4, first handle 5, pivot seat 6, second handle 7.

This scissors system with two cut body involutory mutually after, wear pivot with a hinge pin again and constituted in conjunction with institute, wherein be positioned at the blade 1 that this scissors front end forms the mutual involutory position of blade, position, the rear end formation of scissors supplies first handle 5, second handle 7 of user's holding operation.Dan Rod 3 one end hinges are on second handle 7, and the other end of described Dan Rod 3 leans first handle 5 when scissors is closed.

The medial surface position of second handle 7 is provided with and can supports post 4 against the convex of first handle 5, utilizes this to support post 4 and allows two handles be unlikely excessive closing and the involutory state that influences two blades 1.Bullet property Rod 3 effects are that a scissors two handles automatically spring open, this automatically springs open the middle section position that device lies in second handle 7 and is provided with pivot seat 6, be incorporated into this pivot seat 6 for elasticity Rod 3 can change the pendulum kenel, the Dan Rod 3 Dan Rod 3 that pivot seat 6 upper hinges can change the pendulum kenel are bent into Heng away from pivot seat 6 ends and form a pushing part Xiang the bond sites of Rod body, this pushing part is arranged with the wheel pipe 2 of kenel in a tubular form, this takes turns pipe 2 can be metal pipe material, nonmetal tubing that hardness is bigger, or is the tubular coil spring making; Wheel pipe 2 leans the medial surface of first handle 5 when blade 1 closure.When this bullet Rod 3 commentaries on classics pendulum move between hinge pin and the pivot seat 6, this Dan Rod 3 can rely on the medial surface of first handle 5 with the pushing part of sheathed wheel pipe 2, utilize the elasticity of Dan Rod 3 that two handles are backed down relatively and allow two blades 1 of scissors can keep open stand-by state, use and be convenient to carry out once more shearing manipulation.

Dan Rod 3 is bent into splayed by the metal wire rod one, and Dan Rod 3 forms the pushing part of Dan Rod 3 away from the bond sites of pivot seat 6 ends.Splayed bullet Rod 3 is provided with a straight Rod section that is linked to pivot seat 6, second handle 7 in the medial surface of this pivot seat 6 be provided with can for elasticity Rod 3 straight Rod sections against protruding top.Pivot seat 6 is provided with a pivot hole, and relatively inwardly curved the stretching of the free end of Dan Rod 3 forms Yi Kou Rod respectively, utilizes Liang Kou Rod to align the pivot hole that eye-splice is hubbed at pivot seat 6, and this Dan Rod 3 is incorporated into pivot seat 6 can change the pendulum kenel.

When manipulating, bullet property Rod 3 can be changeed pendulum moves between the hinge pin and pivot seat 6 of scissors, and utilize the elastic force of Dan Rod 3 automatically first handle 5 and second handle 7 to be flicked, and allow two blades 1 keep opening stand-by state, the user can directly carry out shearing manipulation; Because the pushing part of Dan Rod 3 system sees through the medial surface that wheel pipe 2 is resisted against first handle 5, the user with hand with the process of the relative pressing of two handles in the pushing part of Dan Rod 3 can be swimmingly in the medial surface slippage of first handle 5, can not cause improper resistance extra when manipulating, and Dan Rod 3 can utilize bending part Ji the distortion of Zhi Rod section and raise long-pending enough back stretch that produces, when the user decontrols the application of force, can promptly scissors be reverted back to two blades 1, keep open stand-by state, use and be convenient to carry out once more shearing manipulation.

In sum, the composition structure of the utility model integral body is considerably simplified, and it is very convenient to fold or launch to use, particularly utilization is sheathed on the wheel pipe of Dan Rod spare and the deformable design of Dan Rod Zhi Rod section, after excellent back stretch was provided effectively, the frictional resistance between low elasticity Rod spare and handle can further fall.Above illustrated embodiment is only with for conveniently illustrating the utility model, and at technical scheme category described in the utility model, the person of ordinary skill in the field does various simple deformation and modification, all must be included in the above claim.
