[0020] Furthermore, the top centers of the two side clamping plates 3 are connected with the first threaded rod 5 and the fourth threaded rod 12 through threads, and the bottoms of the first threaded rod 5 and the fourth threaded rod 12 are in contact with the top of the gear shaft body 6 .

[0021] Furthermore, a third threaded rod 11 is threadedly connected to the top center of the first clamp 8 , and the other end of the third threaded rod 11 is in contact with the top of the gear shaft body 6 .

[0022] Furthermore, a second threaded rod 10 is threadedly connected to the top center of the second clamp 9 , and the other end of the second threaded rod 10 is in contact with the top of the gear shaft body 6 .

[0023] Furthermore, a knob 15 is fixedly connected to the side surface of one of the two side bottom plates 2 , and an output end of the knob 15 is connected to one end of the bidirectional screw 14 .

[0024] Working principle: Figure 1 As mentioned above, when the gear shaft is milled, the gear shaft will be Figure 1The clamping is performed, specifically, before clamping the gear shaft, the staff needs to move the first clamp 8 and the second clamp 9 to the two side surfaces of the through groove 13, and then place the gear shaft gear 7 between the first clamp 8 and the second clamp 9, and then insert the two sides of the gear shaft body 6 into the placement holes 4 of the first clamp 8 and the second clamp 9 respectively, and then pass the two sides of the gear shaft body 6 through the placement holes 4 of the side clamp 3 respectively, and then rotate the first threaded rod 5 and the fourth threaded rod 12, so that the bottom of the first threaded rod 5 and the fourth threaded rod 12 are in contact with the top of the gear shaft body 6, thereby initially fixing the gear shaft.

[0025] Then the staff rotates the knob 15, and the rotation of the knob 15 will rotate the bidirectional screw 14, and the rotation of the bidirectional screw 14 will move the two sliding blocks 16 toward the middle, and the movement of the two sliding blocks 16 toward the middle will move the first clamp 8 and the second clamp 9 toward the middle. When the inner sides of the first clamp 8 and the second clamp 9 contact the two sides of the gear shaft gear 7, the staff stops rotating the knob 15, and finally the staff rotates the second threaded rod 10 and the third threaded rod 11 in turn, so that the bottom of the second threaded rod 10 and the third threaded rod 11 will connect with the bottom of the gear shaft body 6, thereby fixing the gear shaft again.

[0026] After the gear shaft is fixed, the staff can easily perform milling operation on the gear shaft gear 7.

[0027] It needs to be said that if Figure 1 As shown, the length of the bottom plates 2 on both sides is not as wide as shown in the figure. The width of the bottom plates 2 on both sides is 50 mm. When the first clamp 8 and the second clamp 9 move to the side of the through groove 13, the distance between the first clamp 8 and the second clamp 9 and the side clamp 3 is very small. When the staff inserts the gear shaft body 6 into the placement hole 4 of the first clamp 8 and the second clamp 9 with great difficulty, the placement hole 4 at the side clamp 3 will be immediately inserted with the gear shaft body 6, so that the gear shaft can be better fixed.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
