[0023] In this embodiment, a horizontally arranged rotating rod 14 is fixedly inserted into one end of the worm gear 15 to drive the first helical gear 13 to rotate. One end of the rotating rod 14 passes through the worm gear 15 and is rotatably connected to the inner side wall of the bracket 18. A longitudinally arranged column 3 is fixedly connected to the front of the support plate 2 to support the PEEK gear. A circular storage slot is provided inside the column 3. The first helical gear 13 is rotatably connected to the inner side wall of the storage slot to drive the second helical gear 12 to rotate. The other end of the rotating rod 14 passes through the bracket 18, the support plate 2, the column 3 and the first helical gear 13 in sequence and is rotatably connected to the inner side wall of the storage slot. The rotating rod 14 is rotatably connected to the bracket 18, the support plate 2 and the column 3.

[0024] In this embodiment, multiple first grooves are distributed in a ring on the outer side wall of the support column 3. A clamping block 4 is slidably inserted into the inner side wall of the first groove to clamp the PEEK gear and prevent rotation. One end of the clamping block 4 passes through the slot, and the other end of the clamping block 4 is inserted with a lead screw 9 to drive the clamping block 4 to move. The lead screw 9 and the clamping block 4 are connected by a thread. A first connecting ring 10 is rotatably sleeved on the lead screw 9 to support the lead screw 9. One side of the first connecting ring 10 is fixedly connected to the inner side wall of the first groove. A second connecting ring 11 is rotatably sleeved on the lead screw 9 to support the lead screw 9. One end of the second connecting ring 11 is fixedly connected to the inner side wall of the storage groove. The end of the lead screw 9 away from the clamping block 4 passes through the support column 3 and is fixedly connected to a second helical gear 12 that meshes with the first helical gear 13 to drive the lead screw 9 to rotate. The second helical gear 12 is located in the storage groove.

[0025] In this embodiment, the upper end of the support column 3 is provided with a second sliding groove, and a pin 5 is slidably connected to the inner sidewall of the second sliding groove to cooperate with the pin groove to prevent the PEEK gear from rotating. Guide blocks 8 are fixedly connected to the outer sidewall of the clamping block 4 and the outer sidewall of the pin 5 to cooperate with the guide groove to guide the clamping block 4 and the pin 5. The inner sidewalls of the first and second sliding grooves are provided with guide grooves corresponding to the guide blocks 8. One end of the guide block 8 slides into the guide groove, and the outer sidewall of the guide block 8 is provided with an arc-shaped groove. The inner wall of the guide block 8 is connected with rolling balls to reduce the resistance when the guide block 8 moves with the pin 5 or the clamping block 4. The ball part passes through the arc groove. The upper end of the pin 5 passes through the second slide groove.

The lower end of the fixing ring 7 is fixedly connected to the inner bottom of the second slide groove.

[0026] In this embodiment, firstly, the PEEK gear is fitted onto the support column 3, ensuring that the pin groove on the PEEK gear is aligned with the pin 5. Then, the servo motor 17 is started to drive the worm gear 16 to rotate. Through the meshing transmission between the worm gear 16 and the worm wheel 15, the rotating rod 14 is driven to rotate, which in turn drives the first helical gear 13 to rotate. The first helical gear 13 then drives the multiple second helical gears 12 meshing with it to rotate, ultimately causing the lead screw 9 to rotate. The lead screw 9, through the threaded meshing action, pushes the clamping block 4 to move outward along the first sliding groove until the clamping block 4 is in close contact with the inner wall of the PEEK gear, achieving the clamping and fixing effect and the anti-rotation effect of the PEEK gear. At the same time, the electric push rod 6 is started to drive the pin 5 to rise and insert into the pin groove, further strengthening the anti-rotation effect of the PEEK gear.

[0027] As mentioned above, servo motors and electric linear actuators are existing mature technologies, and their working principles and internal structures are known to those skilled in the art. This application only utilizes their functions and does not improve their internal structures; therefore, it will not be described in detail.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
