[0006] As a further improvement of the utility model, a threaded rod is fixed at a position between the second circular through hole and the supporting vertical plate on the base, an auxiliary support plate is threadedly connected to the threaded rod, and the auxiliary support plate is located below the supporting cross plate. A third circular through hole is provided on the supporting cross plate for the threaded rod to pass through, and the setting of the auxiliary support plate can provide auxiliary support for the supporting cross plate.

[0007] As a further improvement of the present invention, the auxiliary support plate is a strip plate or a cylindrical plate.

[0008] As a further improvement of the utility model, the supporting horizontal plate includes a straight portion and a U-shaped portion, one end of the straight portion is fixedly connected to the middle portion of the U-shaped portion, the U-shaped portion is clamped on the supporting vertical plate, and a first circular through hole is opened on the U-shaped portion. The setting of the U-shaped portion makes the connection between the supporting vertical plate and the supporting horizontal plate more stable.

[0009] The beneficial effect of the utility model is that the utility model solves the problem that the existing chain sleeve removal is generally directly smashed by a sledgehammer, there is no good force point, the removal process takes a long time, and the removal is difficult. The utility model uses a sledgehammer to smash the impact pin and remove the chain sleeve, so as to achieve the purpose of replacing the chain and removing the sleeve. The operation is simple, the force point is clear, and the replacement time is greatly shortened. BRIEF DESCRIPTION OF THE DRAWINGS
