Abstract

The invention relates to a right angle typed screw driver comprising a rotating rod, a retainer I, an outer shell, a screw driver head, a retainer II and a driven rod. The right angle typed screw driver is characterized in that the rotating rod and the driven rod are arranged inside the outer shell and are matched with each other via a bevel wheel, the retainer I and the retainer II are connected with two ends of the outer shell via threads to fix the rotating rod and the driven rod, and the screw driver head is mounted on the driven rod. The right angle typed screw driver is novel and reasonable in structure, simple in operation and is wide in application area.

Description

A kind of right-angle type screwdriver
Technical field
This patent of invention relates to a kind of screwdriver, relates in particular to a kind of right-angle type screwdriver, and this screwdriver belongs to hardware & tools technical field.
Background technology
Screwdriver is to be a kind ofly used for twisting screw to force its instrument in place.Existing screwdriver is all generally straight-bar type, and the position operation space at some the screw place that need to be twisted is less, even some is too concealed, make the operator extended operation space by other means of having to, this not only makes work more loaded down with trivial details, has caused again the waste of great time and resource.In order to make more convenient to operate and to be applied to more normal screws cuttves and can not to realize the occasion of operation, we have proposed a kind of right-angle type screwdriver.
Summary of the invention
For the demand, the invention provides a kind of right-angle type screwdriver, this screwdriver, simple and reasonable, easy to use, can meet the instructions for use in different operating space.
The technical solution adopted for the present invention to solve the technical problems is: a kind of right-angle type screwdriver, comprises rotary bar, stopper I, shell, driver bit, stopper II, follower lever.It is characterized in that: described rotary bar and follower lever are placed in the inside of shell, and rotary bar matches by helical gear with follower lever, described stopper I and stopper II are threaded connection respectively the two ends that are screwed into shell, to play the effect of fixing rotary bar and follower lever, the two ends of shell have external screw thread as shown in Figure 3, and described driver bit is installed on follower lever.
The part that described follower lever contacts with rotary bar has helical gear, and the place contacting with driver bit is provided with interior hexagonal indentations and uses magnetic material to make, to facilitate installation driver bit.Follower lever is provided with boss structure, is fixed in shell by stopper II to facilitate.
The part that described rotary bar contacts with follower lever has helical gear, and the other end is provided with handle, and handle is provided with coarse lines to increase coefficient of friction.Rotary bar is provided with boss structure, is fixed in shell by stopper I to facilitate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing explanation, the invention will be further described.
Fig. 1 is structural representation of the present invention, and Fig. 2 is structural representation explosive view of the present invention, and Fig. 3 is part-structure detailed annotation enlarged drawing.
Wherein, 1-rotary bar, 2-stopper I, 3-shell, 4-driver bit, 5-stopper II, 6-follower lever.
The specific embodiment
As shown in Fig. 1,2: a kind of right-angle type screwdriver, comprises rotary bar, stopper I, shell, driver bit, stopper II, follower lever.It is characterized in that: described rotary bar and follower lever are placed in the inside of shell, and rotary bar matches by helical gear with follower lever, described stopper I and stopper II are threaded connection respectively the two ends that are screwed into shell, to play the effect of fixing rotary bar and follower lever, described driver bit is installed on follower lever.
When use, to the screw that will screw or dismantle, by rotation rotary bar, and then drive follower lever and driver bit to rotate on the screwdriver crown, just can reach the effect that screws or dismantle screw.
