[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a scanner with anti-slip function, including a handheld scanner body 1. The handheld scanner body 1 is a common handheld scanner on the market. The surface of the handheld scanner body 1 is covered with a sweat-absorbing sleeve 23. By setting the sweat-absorbing sleeve 23, it can absorb the sweat generated by the user's palm and increase the friction intensity between the user and the handheld scanner body 1. The bottom of the handheld scanner body 1 is fixedly connected to a transmission box 2. The bottom of the right side of the inner wall of the transmission box 2 is movably connected to a transmission column 3 through a bearing. The surface of the transmission column 3 is fixedly connected to... There is a tension band 4, and limit rings 21 are fixedly connected to both sides of the surface of the transmission column 3. The tension band 4 is located inside the limit rings 21. By setting the limit rings 21, the tension band 4 can be limited to prevent the tension band 4 from being displaced. The inner wall of the transmission box 2 is fixedly connected to an anti-friction pad 24. The bottom of the anti-friction pad 24 contacts the surface of the tension band 4. By setting the anti-friction pad, the wear of the tension band 4 can be reduced and the service life of the tension band 4 can be improved. The side of the tension band 4 away from the transmission column 3 extends to the front of the transmission box 2 and is fixedly connected to the top of the front of the handheld scanner body 1.

[0033] Reference Figures 2-4 A rotating rod 5 is fixedly connected to the left side of the transmission column 3. The left side of the rotating rod 5 extends through to the left side of the transmission box 2 and is fixedly connected to a turntable 6. The surface of the turntable 6 is provided with anti-slip grooves 22. By providing anti-slip grooves 22, the friction force when the user drives the turntable 6 can be increased, preventing slippage when rotating the turntable 6. A ratchet 7 is fixedly connected to the right side of the transmission column 3. A transmission rod 8 is movably connected to the top right side of the inner wall of the transmission box 2 via a bearing. A pawl 9 is fixedly connected to the surface of the transmission rod 8. The pawl 9 meshes with the ratchet 7. A circular sleeve 10 is fixedly connected to the left side of the transmission rod 8. The surface of the circular sleeve 10 is provided with an arc-shaped opening. The arc-shaped opening 11 has a sliding rod 12 inside which a push rod 13 is fixedly connected to the back of the slide rod 12. A push-pull plate 14 is fixedly connected to the left side of the push rod 13. A pad 20 is fixedly connected to the left side of the push-pull plate 14. By setting the pad 20, the contact area of ​​the push-pull plate 14 can be increased, making it easier for the user to push the push-pull plate 14 quickly. The left side of the push-pull plate 14 extends to the left side of the transmission box 2. A spring piece 15 is fixedly connected to the right side of the inner cavity of the transmission box 2 through a connecting plate. The spring piece 15 can quickly drive the pawl 9 to reset. The side of the spring piece 15 away from the connecting plate is fixedly connected to the surface of the pawl 9.

[0034] Reference Figure 1A protective component is provided on the left side of the handheld scanner body 1. The protective component includes a protective cover 16, which is fixedly installed on the top left side of the handheld scanner body 1 via a hinge. A Velcro 17 is fixedly connected to the left side of the protective cover 16. The Velcro 17 is double-sided. A Velcro 28 is fixedly connected to the front of the handheld scanner body 1. There are two Velcro 28s. The Velcro 17 and the Velcro 28 are glued together. By setting up the structure of the protective cover 16, the Velcro 17 and the Velcro 28, the display screen and control buttons of the handheld scanner body 1 can be protected, preventing damage caused by collisions between foreign objects and the display screen and control buttons of the handheld scanner body 1. At the same time, the Velcro 17 and the Velcro 28 can be used together to easily fix the protective cover 16 when it is open and closed.

[0035] Reference Figures 2-3 The transmission box 2 is equipped with a support assembly, which includes a support sleeve 19. The support sleeve 19 is fixedly connected to the top of the inner cavity of the transmission box 2. The surface of the round sleeve 10 is in contact with the inner wall of the support sleeve 19. By setting the support sleeve 19, the round sleeve 10 can be supported and limited, avoiding the phenomenon of the round sleeve 10 shaking during rotation, thus improving the stability of the round sleeve 10 during rotation.

[0036] Working principle: In use, the user first inserts their fingers through the inside of the tension band 4. Then, the turntable 6 drives the rotating rod 5 to rotate, which in turn drives the transmission column 3 to rotate. The transmission column 3 then drives the ratchet 7 to rotate, simultaneously winding the tension band 4 around the user's fingers. The tension band 4 is then tightly pulled taut against the user's fingers. The ratchet 7 is then secured by the pawl 9 to prevent the transmission column 3 from rotating back. Next, the adhesive tape between Velcro 17 and Velcro 2 18 is removed to open the protective cover 16. The adhesive tape between Velcro 17 and Velcro 2 18 is then removed from the opened protective cover 16. Once fixed, the handheld scanner body 1 can be used to scan the object to be scanned. When it is necessary to release the handheld scanner body 1, the user pushes the push-pull plate 14 to the right through the pad 20. The push-pull plate 14 drives the push rod 13 to move to the right. The push rod 13 drives the slide rod 12 to slide inside the arc-shaped opening 11, so that the slide rod 12 drives the sleeve 10 to rotate around the transmission rod 8. The sleeve 10 then drives the pawl 9 to rotate and disengage from the ratchet 7 through the transmission rod 8, thereby loosening the tension band 4 from fixing the finger surface, thus achieving the advantage of good anti-slip effect.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
