Description

Screwdriver structure

The present invention is related to a screw-rotating structure, especially in a screw-rotating structure, the control member rotates on the first body to make the driving member rotate counterclockwise, clockwise, clockwise and counterclockwise The screwdriver rotating structure has three kinds of rotating structure for more operability.

According to our previous knowledge, in the conventional screwdriver or wrench rotation structure, such as US Patent No.: US9296093B2, Taiwan Patent Application No.: 104112990, Certificate No.: I628049, Patent Name: Reversible Roller The biasing and reversing method and mechanism of a clutch ratchet, the structure of the patent case is: a reversible ratchet device, comprising: a ratchet body 102, which includes an inner surface 118, the inner surface 118 is defined as a circular hole; cage-shaped member 108 disposed in the ratchet body 102, and the cage member 108 includes: an annular base 122 disposed within the circular hole 120 and collectively defining a cage hole 126; fingers 124 from the annular base 122 Axial extension, and radial stop 134, extending from the annular base 122 into the cage hole 126; reversing sleeve 116, which is disposed in the cage member 108; drive member 104, which includes a shaft portion 105, the shaft portion 105 is adapted to be rotatably retained by the reversing sleeve 116; the roller 106, which is retained by the cage member 108 between the ratchet body 102 and the drive member 104, and the biasing member 110 , 111, the biasing members 110, 111 are adapted to exert a biasing force between the reversing sleeve 116 and the cage member 108; characterized in that the drive member 104 and the reversing sleeve 116 are relative to each other set in the first displacement and the second displacement on any one.

However, this conventional biasing and reversing method and mechanism for reversible roller clutch ratchets is lacking in:

1. The drive member 104 and the reversing sleeve 116 are optionally defined in a first angular displacement or a second angular displacement relative to each other, when the angular displacement between the drive member 104 and the reversing sleeve 116 is from When the first angular displacement is switched to the second angular displacement, the cage member 108 is configured to switch the plurality of rollers 106 from the corresponding first position on the driving member 104 to the corresponding second position on the driving member 104, that is, the The cage member 108 can only switch the plurality of rollers 106 to the first position or the second position relative to the driving member 104, that is, the plurality of rollers 106 can be located in two positions relative to the driving member 104, and The drive member 104 and the reversing sleeve 116 are relatively limited to a first angular displacement or a second angular displacement to limit the clockwise or counterclockwise rotation of the drive member 104 relative to the ratchet body 102, and so on Rotating the upper system is only clockwise or counterclockwise, and the operability is insufficient.

2. As shown in Figure 1 of the publication, the cage member 108, the biasing member 110, the biasing member 111, the pawl spring 112, the braking ball 114 and the reversing sleeve 116 are provided, There are six elements in total to displace and position the plurality of rollers 106, the biasing and reversing method and mechanism for the reversible roller clutch ratchet is quite complex and increases the reversing structure Cost of all components.

In view of the above-mentioned deficiency of the conventional structure, the inventor of the present invention has finally come out with a screwdriver-rotating structure product which can solve the drawbacks of the conventional structure with years of experience in manufacturing, production and design in related industries.

In the conventional biasing and reversing methods and mechanisms for reversible roller clutch ratchets, the upper rotation system is only clockwise or counterclockwise, and there are only two rotation modes and structural operability systems. Insufficient, in the screwdriver rotating structure of the present invention, the control member rotates on the first body, so that the driving member can rotate counterclockwise, clockwise, and both clockwise and counterclockwise. It has three rotating structures for more convenient operation.

A screwdriver rotating structure includes: a first main body is provided with a plurality of first grooves and a plurality of first protruding posts; each first recess is provided with a first surface, and the first protruding posts are provided with Two second surfaces, two third surfaces and a first pivot; the first main body is protruded with a plurality of second pivots; a control part is provided with a plurality of third pivots and a plurality of second protruding columns; each The second protruding column is provided with a fourth surface, a fifth surface and a fourth pivot portion; a driving member is provided with a fifth pivot portion and a fitting portion; a plurality of first rollers are pivoted on each of the two phases A plurality of second rollers are pivotally arranged in the other first groove of every two adjacent first grooves.

The control member rotates on the first body, so that the driving member can rotate counterclockwise, clockwise, and both clockwise and counterclockwise. The screwdriver rotation structure has three rotation structures, which is more convenient to operate. . The second protruding column is provided on the first roller and the second roller without any support, and the first roller and the second roller are both abutting against the first surface and the wall surface of the fifth pivot portion time, that is, the first system drives the driving member to rotate both clockwise and counterclockwise.

In order to make the committee members and those who are familiar with the art fully understand the effect of the present invention It is understood that the structure and composition of the present invention are described below with reference to the drawings and drawing numbers. However, the following descriptions are only used to explain the embodiments of the present invention, and are not intended to limit the present invention in any form.
