[0009] It should be noted in the solution that a stopper is also fixed on the top surface of the mounting plate, the stopper is triangular in shape, and the right-angled surface of the stopper is arranged on one side of the slide groove and abuts against the fixing clamp.

[0010] Compared with the prior art, the wear-resistant special-shaped bushing provided by the utility model has at least the following beneficial effects:

[0011] (1) By setting the sponge body and the lubricating component, when the bushing is set on the workpiece, the lubricating component will transport the lubricating oil into the sponge body, and then adhere to the outer wall of the workpiece through the sponge body, so as to increase the lubrication effect between the bushing and the workpiece, so that the lubrication effect between the bushing and the workpiece can be maintained for a long time, effectively reducing the wear of the bushing and increasing the service life of the bushing.

[0012] (2) By setting the sealing cover assembly, the annular boss on the locking block faces the outer shell, and the outer shell is rotated so that the annular boss penetrates into the cavity and is threadedly connected to the inner wall of the cavity, thereby sealing the lubricating oil in the cavity.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 A wear-resistant special-shaped bushing comprises an inner core 1, an inner wall of the inner core 1 is provided with an annular groove, a sponge 4 is arranged in the annular groove, and a lubricating component is arranged outside the inner core 1;

[0019] Through the arrangement of the sponge body 4 and the lubricating component, when the bushing is mounted on the workpiece, the lubricating component will transport the lubricating oil into the sponge body 4, and then adhere to the outer wall of the workpiece through the sponge body 4, so as to increase the lubrication effect between the bushing and the workpiece, so that the lubrication effect between the bushing and the workpiece can be maintained for a long time, effectively reducing the wear of the bushing and increasing the service life of the bushing.
