[0047] Furthermore, the limiting assembly 202 includes an annular plate 202a fixedly connected to the rotating tube 201a, a blocking block 202b fixedly connected to the annular plate 202a, a semi-cylinder 202c rotatably connected to the rotating tube 201a, a rotating block 202m fixedly connected to the semi-cylinder 202c, an annular groove 202d provided on the semi-cylinder 202c, the semi-cylinder 202c being rotatably connected to the annular plate 202a on the rotating tube 201a through the annular groove 202d, a vertical groove 202e provided on the rotating tube 201a, a limiting post 202f slidably connected to the vertical groove 202e, and a limiting post 202f fixedly connected to the limiting post 202 f, the limiting column 202f is slidably connected with the vertical groove 202e through the sliding plate 202g, the triangular block 202h fixedly connected to the top of the limiting column 202f, the abutment rod 202i fixedly connected to the semi-cylinder 202c, the connecting plate 202j fixedly connected to the limiting column 202f, the spring 202k fixedly installed and connected between the connecting plate 202j and the connecting block 108c, and the limiting groove 202l opened on the connecting block 108c, the limiting groove 202l is in a circular array on the connecting block 108c, and the limiting column 202f passes through the rotating tube 201a and abuts against the limiting groove 202l.

[0048] When in use, when it is necessary to adjust the length of the sliding plate 108d to adapt to the extraction of bushings 102 of different sizes, the rotating block 202m can be rotated, and the rotating block 202m will drive the semi-cylinder 202c to rotate on the rotating tube 201a, so that the abutment rod 202i on the semi-cylinder 202c will push the triangular block 202h to lift, and the lifted triangular block 202h will drive the limiting column 202f to overcome the elastic force of the spring 202k and move upward along the vertical groove 202e, thereby leaving the limiting groove 202l, and the semi-cylinder 202c will also abut against the blocking block 202b. At this time, the semi-cylinder 202c continues to be rotated, and under the action of the blocking block 202b, the rotating tube 201a will be driven to rotate together, thereby driving the circular plate 201 b rotates, since the fixed column 201d is fixedly connected to the sliding plate 108d, when the circular plate 201b is moved, the fixed column 201d will continuously slide along the sliding groove 201c toward the center or outer edge of the circular plate 201b, and then the sliding plate 108d will be driven to open or close along the connecting block 108c through the fixed column 201d. Therefore, rotating the rotating block 202m can realize the opening or closing of the sliding plate 108d, and after stopping the rotation, the limiting column 202f will be automatically connected with the limiting groove 202l by the thrust of the spring 202k, so as to fix the position of the rotating tube 201a, thereby fixing the position of the sliding plate 108d to prevent the sliding plate 108d from moving and causing danger when the bushing 102 is pulled out.
