[0021] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0022] As Figures 1-4 shown, a non-slip wrench includes a wrench body 1, a retaining piece 2 is welded on the upper side of the wrench body 1, an anti-slip insert piece 3 is inserted on the lower side of the wrench body 1, an anti-slip sliding piece 4 is slidably connected to the upper side of the wrench body 1, a connecting column 5 is bolted between the anti-slip insert piece 3 and the anti-slip sliding piece 4, and the connecting column 5 penetrates through the wrench body 1.

[0023] One end of the wrench body 1 for rotating the bolt is the head. The head of the wrench body 1 is connected to the handle part for holding through an inclined part. Jack holes 6 and slot grooves 7 are provided at the head of the wrench body 1 and the bottom end of the inclined part. The jack hole 6 extends from the inclined part to the inside of the head and communicates with the slot groove 7. A vertical long hole 8 is provided on the inclined part of the wrench body 1, and the jack hole 6 communicates with the long hole 8. A chute 9 is provided on the handle part of the wrench body 1, and protrusions 10 for clamping the anti - detachment sliding piece 4 are provided on both sides of the top end of the chute 9 on the handle part.

[0024] The retaining piece 2 is in a U - shape. The two end heads at the bottom end of the retaining piece 2 are respectively welded on the upper edges on both sides of the head of the wrench body 1. A cavity is formed between the retaining piece 2 and the head of the wrench body 1, and the head end of the bolt is located in the cavity. The retaining piece 2 is used to prevent the head end of the bolt from passing through the head of the wrench body 1.

[0025] The anti - detachment inserting piece 3 is in a zigzag shape. One end of the anti - detachment inserting piece 3 is located in the slot groove 7. The other end of the anti - detachment inserting piece 3 bends upward into the jack hole 6 and then bends again and passes through the jack hole 6. The end of the anti - detachment inserting piece 3 passing through the jack hole 6 is bolted to the bottom end of the connecting column 5. The anti - detachment inserting piece 3 is stuck at the bottom of the head end of the bolt after passing through the slot groove 7, and clamps the head end of the bolt together with the retaining piece 2, thereby preventing the bolt from slipping off.

[0026] The connecting column 5 is square. The connecting column 5 is slidably connected in the long hole 8, and the connecting column 5 passes through the wrench body 1 through the long hole 8. The connecting column 5 slides back and forth in the long hole 8, so that the anti - detachment inserting piece 3 moves back and forth under the drive of the anti - detachment sliding piece 4.

[0027] The anti - detachment sliding piece 4 is inserted into the chute 9 below the protrusion 10. One end of the anti - detachment sliding piece 4 located in the chute 9 is provided with a slider 11 higher than the chute 9. The other end of the anti - detachment sliding piece 4 extends to the outside of the chute 9 and is bolted to the top end of the connecting column 5. The slider 11 is used to facilitate the finger to push the anti - detachment sliding piece 4.

[0028] The working principle of the utility model is:

[0029] When in use, the head of the wrench body 1 is stuck on the head end of the bolt. Due to the blocking effect of the retaining piece 2, the head end of the bolt is located in the cavity formed by the retaining piece 2 and the head of the wrench body 1. At this time, the slider 11 is pushed, so that the anti - detachment sliding piece 4 slides forward in the chute 9, and the connected connecting column 5 and anti - detachment inserting piece 3 slide forward accordingly. One end of the anti - detachment inserting piece 3 is inserted into the bottom of the head end of the bolt, so as to form a clamp on the head end of the bolt together with the retaining piece 2, thereby preventing the bolt from slipping off when the bolt is screwed.

[0030] The anti - detachment sliding piece 4 and the anti - detachment inserting piece 3 are both bolted to the connecting column 5 and can be disassembled, so that they can be disassembled and replaced after the components are damaged, which is convenient for maintenance.
