[0030] The main bevel gear 11 rotates to drive the slave bevel gear 10 to rotate, and the slave bevel gear 10 rotates to drive the bidirectional screw 4 to rotate. Since the moving parts 5 are limited by the limit plate 8, the rotation of the bidirectional screw 4 can drive the two groups of moving parts 5 thereon to move symmetrically, so that the purpose of changing the angle of the transfer rod 6 can be achieved by adjusting the spacing between the two groups of moving parts 5, and then the pressure piece 7 can be driven to expand or contract by adjusting the angle of the transfer rod 6, and finally the two groups of symmetrical pressure pieces 7 can be pressed against the inner ring wall of the gear, thereby completing the fixation of the gear. It is not only suitable for gears of different sizes, but also will not cause obstruction to the outer teeth of the gear, which is convenient for subsequent detection operations.

[0032] The movable member 5 is limited by the limiting plate 8 so that it can be normally lifted and lowered under the drive of the bidirectional screw rod 4, thereby ensuring the rationality of the structure.

[0033] See also Figure 3The outer side of the rotating shaft 12 is fixedly sleeved with a first bearing seat 13 near the left and right ends, and the first bearing seat 13 is fixedly connected to the upper fixed plate 2. A worm wheel 14 is fixedly sleeved in the middle position of the rotating shaft 12, and a worm 15 is meshedly connected at the lower end of the worm wheel 14.

[0037] Working principle: By turning the knob 17, the worm 15 can drive the worm wheel 14 to rotate, and the rotation of the worm wheel 14 drives the rotating shaft 12 to rotate, and the rotation of the rotating shaft 12 can drive the main bevel gear 11 to rotate, and the rotation of the main bevel gear 11 drives the slave bevel gear 10 to rotate, and the rotation of the slave bevel gear 10 drives the bidirectional lead screw 4 to rotate. Since the moving parts 5 are limited by the limit plate 8, the rotation of the bidirectional lead screw 4 can drive the two groups of moving parts 5 thereon to perform symmetrical movement, so that the angle of the transfer rod 6 can be changed by adjusting the spacing between the two groups of moving parts 5, and then the pressure part 7 can be driven to expand or contract by adjusting the angle of the transfer rod 6, so that the two groups of moving parts 5 can be moved symmetrically. The symmetrical pressing piece 7 is pressed against the inner wall of the gear to fix the gear. It is not only suitable for gears of different sizes, but also will not block the outer teeth of the gear, which is convenient for subsequent detection operations. In addition, by turning on the detection motor 20, its output end can drive the first bevel gear 21 to rotate, and the rotation of the first bevel gear 21 can drive the second bevel gear 19 to rotate. The rotation of the second bevel gear 19 can drive the transmission rod 1 to rotate, and the rotation of the transmission rod 1 drives the fixed plate 2 to rotate, and finally drives the gear fixed on the outside of the pressing piece 7 to rotate, so that the staff can detect the transmission of the gear and more intuitively observe whether the gear can be used normally, thereby improving the detection efficiency.
