Thus, by providing the base 524 and the cover plate 526 on the housing 52, the first movable block 542, the first elastic member 544, the second movable block 546, the second elastic member 548 and the abutting member 56 are conveniently disposed on the housing 52, so that the abutting mechanism 50 is easy to assemble, and the assembling difficulty of the abutting mechanism 50 is conveniently reduced. In the present embodiment, the clamping groove 522 is formed on the base 524 and is disposed adjacent to the cover 526.

Along the moving direction of the abutting member 56, the first movable block 542 includes a first body 5422, a first connecting portion 5424 and a first hooking portion 5426 that are sequentially connected, the second movable block 546 includes a second hooking portion 5462, a second connecting portion 5464 and a second body 5466 that are sequentially connected, the first hooking portion 5426 is disposed between the second body 5466 and the second hooking portion 5462, the second hooking portion 5462 is disposed between the first body 5422 and the first hooking portion 5426, two ends of the first elastic member 544 are respectively abutted against the first body 5422 and the base 524 of the housing 52, two ends of the second elastic member 548 are respectively abutted against the first body 5422 and the second hooking portion 5462, one end of the abutting member 56 is connected to the second body 5466, and one end of the first body 5422 far from the first connecting portion 5424 is exposed outside the housing 52.

In this embodiment, the first body 5422 is approximately in a "convex" shape, the number of the first elastic members 544 is two, the two first elastic members 544 are symmetrically disposed, one ends of the two first elastic members 544 are disposed in two sidewalls of the first connecting portion 5424, and the other ends of the two first elastic members 544 are abutted with the groove walls in the housing 52. Thus, by providing the two first elastic members 544, the first movable block 542 is kept balanced, and the first movable block 542 is prevented from being deflected during sliding, so that the sliding direction of the second movable block 546 and the abutting member 56 is affected. By providing the first movable block 542 with the first hooking portion 5426 and the second movable block 546 with the second hooking portion 5462, the first movable block 542 and the second movable block 546 are hooked with each other, and since the second elastic member 548 is elastically telescopic, when the abutting member 56 abuts against the tool sleeve 400, the abutting member 56 is elastically abutted against the tool sleeve 400, the abutting member 56 can be retracted under force and the second elastic member 548 is extruded by the second movable block 546, thereby reducing damage to the tool sleeve 400 caused by the abutting member 56 striking the tool sleeve 400. After the power driving member 62 of the power mechanism 60 is retracted to be separated from the first movable block 542, the first movable block 542 pulls the second movable block 546 and the abutting member 56 to retract under the elastic restoring action of the first elastic member 544, thereby achieving the restoration of the abutting member 56.
