Description

Technical Field

[0001] This utility model relates to a sleeve, specifically an anti-slip sleeve. Background Technology

[0002] A hex socket is used to tighten screws. After the socket is placed on the head of the screw, the screw can be turned. In the conventional design of hex sockets, the force applied when tightening screws is too strong, which reduces the life of the screw. The six corners of the hex screw will wear down and become rounded. After wear, the hex corners will not be able to effectively grip the damaged screw and will not be able to turn the screw effectively. Utility Model Content

[0003] In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide an anti-slip sleeve.

[0004] The technical solution of this utility model is: an anti-slip sleeve, including a sleeve body, the sleeve body is cylindrical, one end of the sleeve body is a fitting part, the fitting part has an internal hexagonal groove, the inner wall of the internal hexagonal groove has multiple ratchet teeth and multiple arc grooves, the multiple ratchet teeth and multiple arc grooves are arranged in a spaced ring, the number of ratchet teeth and arc grooves is six, each ratchet tooth has three adjacent grooves, and a ratchet tooth is provided between every two arc grooves.

[0005] Furthermore, the other end of the sleeve body is a drive unit for connecting tools, and the drive unit has an inner four-corner groove.

[0006] Furthermore, the triangular groove is an equilateral triangular groove.

[0007] Furthermore, there is no gap between the three adjacent grooves.

[0008] The advantages of using the anti-slip sleeve provided by this utility model are as follows: when the screw head is rotated with the anti-slip sleeve, the hexagon of the screw head can be inserted into the arc groove, which can avoid wear on the hexagon of the screw head; each ratchet has three adjacent grooves, and when the screw head is rotated with the anti-slip sleeve, the screw head will contact the ratchet, making it less likely to slip when tightening the screw, thus achieving an anti-slip effect. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the overall structure of this utility model;

[0010] Figure 2 This is another overall structural schematic diagram of the present invention.

[0011] As shown in the figure: 1—sleeve body, 11—fitting part, 111—internal hexagonal groove, 112—ratchet, 1121—groove, 113—arc groove, 12—drive part. Detailed Implementation

[0012] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0013] like Figure 1 , Figure 2 As shown, the anti-slip sleeve includes a sleeve body 1, which is cylindrical. One end of the sleeve body 1 is a fitting part 11, which has an internal hexagonal groove 111. The inner wall of the internal hexagonal groove 111 has multiple ratchet teeth 112 and multiple arc grooves 113, which are arranged in a spaced-apart ring. There are six ratchet teeth 112 and six arc grooves 113. Each ratchet tooth 112 has three adjacent grooves 1121, and one ratchet tooth 112 is provided between every two arc grooves 113. The triangular grooves are equilateral triangular grooves. There is no gap between the three adjacent grooves 1121.

[0014] The other end of the socket body 1 is a drive unit 12 for connecting tools, and the drive unit 12 has internal four corner grooves. The socket body 1 can be a through-type socket structure, a box wrench structure, a ratchet structure, a slide bar structure, a universal joint slide bar structure, or a floating joint structure.

[0015] The anti-slip sleeve provided by this utility model allows the hexagon of the screw head to extend into the arc groove 113 when the screw head is rotated using the anti-slip sleeve, thus preventing wear on the hexagon of the screw head. Each ratchet 112 has three adjacent grooves 1121. When the anti-slip sleeve rotates the screw head, the screw head will contact the ratchet 112, making it less likely to slip when tightening the screw, thus achieving an anti-slip effect.

[0016] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
