Bush dismounting tool and dismounting method thereof

The invention discloses a bush dismounting tool and a dismounting method thereof. The bush dismounting tool comprises a guide rod, an inertia body sliding block and a check block, wherein the inertia body sliding block is arranged on the guide rod in a sleeving mode and is in sliding connection with the guide rod, and the check block is in threaded connection with an external thread at the front end of the guide rod. According to the device, with the help of a wide space on one side, inertia force acts on the lining through the matching effect of the guide rod and the inertia body sliding block, and the lining can be conveniently and rapidly disassembled. 本发明公开了一种衬套拆卸工具及其拆卸方法，其中所述衬套拆卸工具包括导向杆、套装于所述导向杆上且与所述导向杆滑动连接的惯性体滑块以及与所述导向杆前端的外螺纹形成螺纹连接的挡块。本发明借助一侧开阔的空间，利用导向杆和惯性体滑块的配合作用，将惯性力作用于衬套上，方便快捷的将衬套拆卸下来。
