Arc-shaped push blocks 3 matched with the arc-shaped resisting blocks 7 are provided at both ends inside the push ring 2. Clamping and limiting components are provided at the edges of both ends of the top of the bottom plate 1.

[0028] The disassembly and assembly component includes a clamping plate 10, a bidirectional screw 11 and a first guiding sliding groove 12. The first guiding sliding groove 12 is located at the middle position of the bottom of the bottom plate 1. A bidirectional screw 11 extending to the outside thereof is provided on one side inside the first guiding sliding groove 12. Clamping plates 10 matched with it are threadedly sleeved on both sides of the outside of the bidirectional screw 11, and the clamping plates 10 cooperate with the first guiding sliding groove 12 and extend to the outside thereof.

[0029] The clamping and limiting assembly includes a limiting groove 8, a limiting rod 14, a second spring 15, a sleeve 16 and a fixing rod 17. There are multiple groups of limiting grooves 8, and multiple groups of limiting grooves 8 are opened at both ends outside the pushing ring 2. There are two groups of fixing rods 17, and the two groups of fixing rods 17 are located at the middle positions of the two ends of the top of the bottom plate 1. Sleeves 16 are provided at the tops of the two groups of fixing rods 17.

[0030] One ends of the multiple groups of limiting grooves 8 close to the two groups of limiting rods 14 are made of an arc-shaped structure, and the two arc-shaped piece structures are matched with each other.

[0031] Guide inclined surfaces are provided on one sides of the two arc-shaped pushing blocks 3 far from each other and on one sides of the two arc-shaped resisting blocks 7 far from each other, and the two guide inclined surfaces are matched with each other.

[0034] A dialing plate is provided on one side of the bidirectional screw rod 11 away from the first guide chute 12, and anti-slip lines are evenly provided on the outer part of the dialing plate.

[0035] Working principle: During use, an operator can directly take the bottom plate 1 and the components above it and place them at the designated position of the gear shaper. Then, by rotating the bidirectional screw rod 11 inside the clamping plate 10, and then limited by the first guide chute 12, the clamping plate 10 can be driven to move and approach inside the outer part of the bidirectional screw rod 11 and inside the first guide chute 12. Through the movement and approach of the first guide chute 12, the assembly and fixation of the bottom plate 1 and the components above it with the gear shaper can be realized, so as to facilitate the operator to carry out the disassembly, assembly, inspection and repair work of the bottom plate 1 and the components above it in the later stage. Compared with the traditional fixed structure design, this disassembly and assembly design is more flexible;

[0036] Meanwhile, the operator can place the workpiece to be processed inside the two sets of clamping blocks 6, and then rotate the pushing ring 2 inside the annular sliding groove 9. At the same time, due to the arc-shaped structure design on the side of the limiting groove 8 close to the limiting rod 14, when the pushing ring 2 drives the limiting groove 8 to rotate and move, the arc-shaped structure can push the limiting rod 14 to move inside the sleeve 16, realizing the compression operation of the second spring 15. At the same time, the pushing ring 2 can also drive the arc-shaped pushing block 3 to rotate and move. Through the guiding inclined plane design on the side of the arc-shaped pushing block 3 close to the arc-shaped resisting block 7, the arc-shaped resisting block 7 can be pushed to drive the sliding plate 4 to move inside the second guiding sliding groove 13, and then the compression operation of the first spring 5 is realized. At the same time, the movement of the sliding plate 4 can also drive the two sets of clamping blocks 6 to approach each other to realize the fixed clamping of the workpiece to be processed. When the rotation of the pushing ring 2 is completed, the elastic restoring force of the second spring 15 can drive the limiting rod 14 to be restored and inserted into the limiting groove 8 to realize the fixed limit of the rotation of the pushing ring 2 and the above components. Through the structural design of this component, the convenience and firmness of fixing and limiting the workpiece to be processed in the later stage can be effectively improved, enabling the operator to only perform one thread-tightening operation.

Within the knowledge scope of those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
