Through the synchronous rotation of the two second motors 2105, the clamped gear can be driven to rotate and adjust its angle. Through the operation of the adjustment structure 21, the clamping column 20 can be extended out of the rotating plate 18. When the length of the clamping column 20 outside the rotating plate 18 is greater than the sleeve 19, the two clamping columns 20 move toward each other to clamp and fix the front and back sides of the gear, and the clamping effect is more comprehensive and more practical.

[0024] Embodiment 2, as Figure 1-4As shown, the driving structure 5 includes a bidirectional screw 501 arranged in the main board 1, and both ends of the outer wall of the bidirectional screw 501 are threadedly connected with a moving block 502, one end of the two moving blocks 502 is fixed with a connecting block 503, and the ends of the two connecting blocks 503 away from the moving block 502 penetrate the main board 1 and are respectively fixed to the two moving plates 2, and both ends of the moving block 502 are slidably connected to the limiting column 504, and the adjustment structure 21 includes an inner cavity 2101 opened in the rotating plate 18, and the clamping column 20 An extension plate 2102 is fixed on the outer wall in the inner cavity 2101, a driving plate 2103 is fixed at one end of the extension plate 2102, an end of the driving plate 2103 away from the extension plate 2102 passes through the rotating plate 18 and is arranged outside the rotating plate 18, and second fixing plates 2104 are fixed at both ends of the outer wall of the rotating plate 18, a second motor 2105 is installed at one end of one of the second fixing plates 2104, and the output end of the second motor 2105 passes through one of the second fixing plates 2104 and is fixed with a threaded rod 2106, the threaded rod 2106 is threadedly connected to the driving plate 2103, one end of the bidirectional screw 501 is fixed with a connecting column 7, the connecting column 7 passes through one end of the main board 1 and is fixed with a push plate 8, a push block 9 is fixed on the outer wall of the push plate 8, one end of the main board 1 is provided with an opening 10, the push plate 8 is arranged in the opening 10, the bottom end of the main board 1 is provided with a moving groove 6 matching the connecting block 503, both ends of the limiting column 504 are fixed to the main board 1, and the other end of the bidirectional screw 501 is fixed to the main board 1.

[0025] The effect achieved by the entire embodiment 2 is that the user rotates the push plate 8 to drive the bidirectional screw 501 to rotate, so that the two moving blocks 502 move toward each other under the limit of the limit column 504, thereby driving the two moving plates 2 to move toward each other, so that the main board 1 can be clamped and fixed by the two moving plates 2 moving toward each other while being convenient for clamping the outside world. By driving the second motor 2105 to operate, the threaded rod 2106 is driven to rotate, so that the driving plate 2103 moves under the limit of the slide groove 22, thereby driving the clamping column 20 connected to the extension plate 2102 to move, so that the clamping column 20 extends out of the rotating plate 18.

After installation, it is adjusted according to the actual clamping situation of the gear. When it is necessary to clamp and fix through the meshing mouth of the gear, the two connecting plates 16 can be driven to move toward each other through the synchronous operation of the two telescopic rods 15, thereby driving the two The two sleeves 19 fixed by the rotating plate 18 move toward each other, so that they can be clamped and fixed by the meshing of the gears. Through the synchronous rotation of the two second motors 2105, the clamped gears can be driven to rotate and their angles can be adjusted. When it is necessary to clamp the front and back sides of the gears, it is only necessary to control the operation of the second motor 2105 before the operation of the telescopic rod 15 to drive the threaded rod 2106 to rotate, so that the driving plate 2103 moves under the limit of the slide groove 22, thereby driving the clamping column 20 connected to the extension plate 2102 to move, so that the clamping column 20 extends out of the rotating plate 18. When the length of the clamping column 20 outside the rotating plate 18 is greater than the sleeve 19, the two clamping columns 20 move toward each other to clamp and fix the front and back sides of the gears.
