[0020] In this embodiment, when the threaded rod 10 rotates clockwise, the threaded rod 10 and the guide block 7 are threadedly engaged, causing the guide block 7 to move toward the center of the positioning platform 1 in the guide groove 2, and when the threaded rod 10 rotates counterclockwise, the threaded rod 10 and the guide block 7 are threadedly engaged, causing the guide block 7 to move away from the center of the positioning platform 1 in the guide groove 2.

[0021] An inner cavity 11 is provided at the inner center of the positioning platform 1, and a bevel gear assembly is installed inside the inner cavity 11. The threaded rod assembly is connected to the bevel gear assembly, and the bevel gear assembly includes a bevel gear 12, a vertical shaft 13, a bevel gear 2 14 and a bevel gear 6 19. The bearing of the vertical shaft 13 is connected in the middle of the inner cavity 11, the bevel gear 12 is fixed on the upper part of the vertical shaft 13, and the bevel gear 6 19 is fixed on the lower part of the vertical shaft 13. There are four bevel gears 2 14, which are respectively meshed and connected around the upper end of the bevel gear 12. The inner end of the threaded rod 10 passes through the inner cavity 11 and is fixed to the corresponding bevel gear 2 14.

[0022] In this embodiment, when bevel gear six 19 rotates, it can drive the vertical shaft 13 to rotate, and the vertical shaft 13 drives the bevel gear one 12 to rotate. As the bevel gear one 12 is synchronously meshed with the four bevel gears two 14, the four bevel gears two 14 rotate at the same time, so that the bevel gear two 14 can drive the threaded rod 10 to rotate, thereby making the four threaded rods 10 rotate synchronously.

[0023] A hollow seat 3 is fixed at each of the four corners of the positioning platform 1, a knob 4 is rotatably connected to the upper end of the hollow seat 3, a transmission assembly is connected between the lower part of the knob 4 and the lower part of the bevel gear assembly, the transmission assembly comprises a transverse axis 15, bevel gear three 16, bevel gear four 17 and bevel gear five 18, the transverse axis 15 passes through and is rotatably connected to the positioning platform 1, the transverse axis 15 passes through and is rotatably connected to the hollow seat 3, the bevel gear three 16 and the bevel gear five 18 are respectively fixed at the first and last ends of the transverse axis 15, the bevel gear three 16 is located below the bevel gear six 19 and is meshed with the bevel gear six 19, the bevel gear four 17 is meshed with the bevel gear five 18 above, the lower part of the knob 4 passes through the hollow seat 3 and is fixed to the bevel gear four 17.

[0024] In this embodiment, when the knob 4 is rotated, the bevel gear four 17 can be driven to rotate, and the bevel gear four 17 is engaged with the bevel gear five 18 to drive the bevel gear five 18 to rotate, and the bevel gear five 18 will drive the horizontal shaft 15 to rotate, and the horizontal shaft 15 will drive the bevel gear three 16 to rotate, and as the bevel gear three 16 is engaged with the bevel gear six 19, the bevel gear six 19 is driven to rotate.

[0025] A lower magnetic ring 6 located below the knob 4 is fixed to the upper end of the hollow seat 3 , and an upper magnetic ring 5 is attracted to the upper side of the lower magnetic ring 6 , and the upper magnetic ring 5 is fixed to the knob 4 .

[0026] In this embodiment, when the knob 4 is rotated, the upper magnetic ring 5 can be driven to rotate. At this time, the upper magnetic ring 5 and the lower magnetic ring 6 slide. When the knob 4 is not rotated, the upper magnetic ring 5 and the lower magnetic ring 6 are attracted to each other, which can improve the stability of the knob 4 when the knob 4 is not rotated and prevent the knob 4 from rotating on its own.

[0027] Working principle: When the spacer is arranged at the upper end of the positioning table 1 and located outside the four clamping seats 8, the knob 4 can be turned to drive the bevel gear 4 17 to rotate, and the bevel gear 4 17 is meshed with the bevel gear 5 18 to drive the bevel gear 5 18 to rotate, and the bevel gear 5 18 will drive the horizontal shaft 15 to rotate, and the horizontal shaft 15 will drive the bevel gear 3 16 to rotate. As the bevel gear 3 16 is meshed with the bevel gear 6 19, the bevel gear 6 19 is driven to rotate. When the bevel gear 6 19 rotates, the vertical shaft 13 can be driven to rotate, and the vertical shaft 13 drives the bevel gear 1 12 to rotate. The bevel gear 1 12 is synchronously meshed with the four bevel gears 2 14, so that the four bevel gears 2 14 rotate at the same time, so that the bevel gear 2 14 can drive the threaded rod 10 to rotate, so that the four threaded rods 10 rotate synchronously. When the threaded rod 10 rotates counterclockwise, as the threaded rod 10 and the guide block 7 are threadedly matched, the guide block 7 moves in the guide groove 2 away from the center of the positioning platform 1. As the four clamping seats 8 are spaced apart, the arc plate 9 on the outside of the clamping seat 8 is used to clamp and position the spacer from the inside of the spacer, and then the spacer can be conveniently processed.
