[0027] A fixed disk 3 is arranged at the output end of the driver 2, and an elastic clamping mechanism 4 is installed on one side of the fixed disk 3 for clamping the worm;
[0028] The elastic clamping mechanism 4 includes a fixed sleeve 41, a conical seat 42, a strip groove 43, a clamping portion 44 and an extrusion seat 45. The fixed sleeve 41 is fixedly installed on one side of the fixed disk 3, and a conical seat 42 is installed on one side of the sleeve. The clamping portion 44 is fixedly installed on one side of the conical seat 42, and four evenly distributed strip grooves 43 are opened in the fixed sleeve 41, and one end of the four strip grooves 43 extends to the inside of the conical seat 42 and the clamping portion 44. The surface of the fixed disk 3 is threadedly installed with an extrusion seat 45, and the inner wall of the extrusion seat 45 is movably sleeved on the surface of the fixed sleeve 41, and the interior of the extrusion seat 45 is provided with a conical portion adapted to the conical seat 42.
[0029] The surface of the extrusion seat 45 is integrally processed with a hexagonal block 5, and one side of the four strip grooves 43 is connected with a hollow groove 6, and the four hollow grooves 6 are all opened on the surface of the fixed sleeve 41;
[0030] In this embodiment, one end of the worm that needs to be fixed and clamped is inserted into the clamping portion 44, and finally one end of the worm is inserted into the fixed sleeve 41. If the diameter of the worm is large, during the insertion process of the clamping portion 44, the clamping portion will be squeezed to drive the conical seat 42 to expand outward. If the diameter of the worm is small, inserting it into the fixed sleeve 41 will not cause the clamping portion 44 and the conical seat 42 to move. Regardless of whether the diameter of the worm is large or small, the extrusion seat 45 is driven to rotate by rotating the hexagonal block 5, and the inner wall of the extrusion seat 45 is threadedly installed with the surface of the fixed disk 3, and the conical portion on one side of the pressurizing seat will first contact the conical seat 42, driving the four conical seats 42 to move closer to each other to achieve elastic clamping and fixation of the worm, which is suitable for different types of worms. The four strip grooves 43 are used as reserved spaces for the four conical seats 42 to approach each other.
[0031] A moving platform 8 is installed on the top of the operating table 1 through a driving member 7, and a positioning seat 9 is rotatably installed on one side of the moving platform 8, and the positioning seat 9 is set in a cone shape;
[0032] Specifically, a conical alignment seat 9 is provided for inserting into the interior of one end of the worm, and the conical setting is used to directly insert into the inner wall of one end of worms of different specifications, without the need to frequently replace the alignment seat 9.

The driving cylinder 71 is fixedly installed at the bottom of the operating table 1, and the pushing seat 72 is fixedly installed at the extended end of the driving cylinder 71. The top of the pushing seat 72 passes through the slide groove 73 in the operating table 1 and is installed at the bottom of the moving table 8.
[0034] Furthermore, the driving cylinder 71 is started to drive the push seat 72 to slide in the slide groove 73, wherein the top of the push seat 72 is connected to the bottom of the moving platform 8, so the moving platform 8 is adjusted according to the different lengths of the worm.
[0035] A reinforcement seat 10 is fixedly mounted on the surface of the driving cylinder 71, and the top of the reinforcement seat 10 is fixedly mounted on the bottom of the operating table 1 by bolts;
[0036] It should be noted that the reinforcement seat 10 is provided to reinforce the drive cylinder 71 installed at the bottom of the operating table 1 , so as to strengthen the fixation of the drive cylinder 71 .

[0040] The axis of the alignment seat 9 and the axis of the fixed sleeve 41 are located at the same center, so as to avoid the two ends of the worm fixed by the cup not being at the same center, resulting in the driver 2 driving the worm to rotate unsmoothly, affecting the subsequent processing quality.
[0041] The device inserts one end of the worm that needs to be fixed and clamped into the clamping part 44, and finally inserts one end of the worm into the fixed sleeve 41. If the diameter of the worm is large, during the insertion of the clamping part 44, the clamping part will be squeezed to drive the conical seat 42 to expand outward. If the diameter of the worm is small, inserting it into the fixed sleeve 41 will not cause the clamping part 44 and the conical seat 42 to move. Regardless of whether the diameter of the worm is large or small, the extrusion seat 45 is driven to rotate by rotating the hexagonal block 5, and the inner wall of the extrusion seat 45 is threadedly installed with the surface of the fixed disk 3, and the conical part on one side of the pressurizing seat will first contact the conical seat 42, driving the four conical seats 42 to move closer to each other to achieve elastic clamping and fixing of the worm, adapting to different types of worms, and the four strip grooves 43 are used as reserved spaces for the four conical seats 42 to approach each other. Start the driving cylinder 71 to drive the push seat 72 to slide in the slide groove 73, where the top of the push seat 72 is connected to the bottom of the moving platform 8, so the moving platform 8 is adjusted according to the different lengths of the worm.
