[0006] Furthermore, a positioning hole is provided on the side wall of the outer sleeve, and a positioning baffle is provided in the positioning hole.

[0007] Furthermore, a positioning groove is provided on the outer wall of the inner screw, and a positioning cone is provided in the positioning groove.

[0008] Furthermore, the positioning mechanism includes a positioning block, a positioning spring, a positioning conical surface and a positioning slide groove, the positioning slide groove is arranged on the positioning block, the positioning block is located in the positioning hole, the positioning baffle is located in the positioning slide groove, the two ends of the positioning spring are respectively abutted against the wall surface of the positioning slide groove and the positioning baffle, the positioning conical surface is arranged on the positioning block, and the positioning conical surface is in contact with the positioning cone.

[0009] Furthermore, the inner screw is threadably connected to the outer sleeve.

[0010] Compared with the prior art, the utility model has the following advantages: after the gear shaft is transferred to the specified position by using the gear shaft placement rack for the worm gear reducer, the positioning cone is disengaged from the positioning cone surface by twisting the inner screw, and then the positioning block is disengaged from the placement plate slot. At this time, the placement plate and the gear shaft can be taken out synchronously, and then the placement plate and the gear shaft are placed in the furnace together with the gear shaft for calcination. The placement rack is convenient for fixing or removing the placement plate, which can improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
