[0018] When the gear ring body 101 needs to be engaged and clamped, the toothed clamping block 301 that is compatible with the gear ring body 101 is installed on the adjusting mechanism 200 using the quick-release mechanism 300. The gear ring body 101 is engaged and clamped by the adjusting mechanism 200, so that the gear ring body 101 is stably placed on the surface of the shell 100. By replacing different toothed clamping blocks 301, more gear ring bodies 101 of different specifications can be engaged and clamped without replacing the entire set of clamps, thereby enhancing the convenience and flexibility of the use of the clamp, expanding the wide adaptability of the clamp to gear ring bodies 101 of different specifications, and improving the efficiency of the overall clamping operation of the clamp.

[0019] In this embodiment, the adjustment mechanism 200 includes a movable guide rail 205 installed on the base plate 103, and two symmetrical guide blocks 207 are slidingly provided on the movable guide rail 205. A movable plate 204 is fixed on the top of the guide block 207. An adjustment block 202 is rotatably provided at the middle position of the movable guide rail 205, and the side wall of the adjustment block 202 abuts against the side wall of the movable plate 204. The adjustment block 202 is transmission-connected to a motor 201, and the motor 201 is fixedly installed on the shell 100.

[0020] The motor 201 is used to drive the adjustment block 202 to rotate. Through the rotation of the adjustment block 202, the two movable plates 204 are driven to move away from each other, and the guide block 207 is driven to move along the movable guide rail 205, ensuring that the movable plate 204 moves along the direction of the movable guide rail 205, avoiding the movable plate 204 from being offset, enhancing the overall stability of the clamp, adjusting the distance between the movable plates 204, and then adjusting the distance between the toothed clamping blocks 301, so as to engage and clamp gear ring bodies 101 of different specifications, thereby enhancing the practicality of the clamp.

[0021] In this embodiment, fixing rods 206 are symmetrically provided on the side walls of the movable plates 204 , and a spring 203 is sleeved between the fixing rods 206 corresponding to the two movable plates 204 .

[0022] By providing the spring 203 , the side wall of the movable plate 204 is always in contact with the side wall of the adjustment block 202 , thereby improving the flexibility of the clamp during adjustment.

[0023] In this embodiment, the quick-release mechanism 300 includes a mounting post 302 fixedly mounted on the movable plate 204, the mounting post 302 being slidably arranged in the movable groove 102, a mounting hole 303 being provided on the mounting post 302, the toothed clamping block 301 being installed on the mounting post 302, a mounting plate 304 being provided on the mounting post 302, the bottom of the mounting plate 304 being in contact with the top of the toothed clamping block 301, a groove 307 being provided on the mounting plate 304, a movable rod 308 being movably arranged in the groove 307, a knob 305 being fixedly provided on the top of the movable rod 308, a compression spring 306 being sleeved on the movable rod 308 of the groove 307 and the knob 305, a limit block 309 being fixedly provided on the end of the movable rod 308 which is adapted to the mounting hole 303.

[0024] According to the shape of the ring gear body 101, select a suitable toothed clamping block 301, sleeve and install the toothed clamping block 301 on the mounting column 302, insert the moving rod 308 into the mounting hole 303, turn the knob 305, and drive the moving rod 308 to rotate 90 degrees through the knob 305, so that the limit block 309 is misaligned with the mounting hole 303, and drive the moving rod 308 to move upward through the compression spring 306, and use the limit block 309 to limit the position, so that the toothed clamping block 301 is fixed on the mounting column 302, which is convenient for engaging and clamping the ring gear body 101. The operation is simple, time-saving and labor-saving, and the toothed clamping block 301 is convenient for quick replacement, convenient for the fixture to clamp ring gear bodies 101 of different specifications, and expands the scope of application of the fixture.

[0025] Working process and principle: When using this device, according to the shape of the gear ring body 101, select the appropriate tooth-shaped clamping block 301, sleeve the tooth-shaped clamping block 301 and install it on the mounting column 302, insert the moving rod 308 into the mounting hole 303, turn the knob 305, and drive the moving rod 308 to rotate 90 degrees through the knob 305, and drive the moving rod 308 to move upward through the compression spring 306, and use the limit block 309 to limit it, so that the tooth-shaped clamping block 301 is fixed on the mounting column 302, which is convenient for engaging and clamping the gear ring body 101. The operation is simple, time-saving and labor-saving, and the tooth-shaped clamping block 301 can be quickly replaced. The fixture is convenient for clamping gear ring bodies 101 of different specifications, expanding the scope of application of the fixture, and using the motor 201 to drive the adjustment block 202 to rotate. Through the rotation of the adjustment block 202, the two movable plates 204 are driven to move away from each other, and the guide block 207 is driven to move along the movable guide rail 205, ensuring that the movable plate 204 moves along the direction of the movable guide rail 205, avoiding the movable plate 204 from being offset, enhancing the overall stability of the fixture, adjusting the distance between the movable plates 204, and then adjusting the distance between the toothed clamping blocks 301, so as to engage and clamp gear ring bodies 101 of different specifications, thereby enhancing the practicality of the fixture.
