When the bolt is disassembled, the first elastic piece 60 is matched with the sliding sleeve 30, so that the sliding sleeve 30 can be always pressed on the external equipment 200 for installing the bolt, and the bolt screwing operation can be still performed when a certain error exists between the disassembling and assembling device and the axial direction of the bolt. In some embodiments, the first elastic member 60 may be a spring, and the spring is sleeved on the cylindrical body 21. Of course, it is understood that in other embodiments, the first elastic member 60 is not limited to be a spring, and the first elastic member 60 may be a spring plate or other.

In some embodiments, the second resilient member 70 may be a spring. Of course, it is understood that in other embodiments, the second elastic member 70 may not be limited to a spring, but may be a spring plate or the like. The screwing mechanism 20 can freely adjust the axial position under the action of the second elastic member 70, on one hand, when the bolt is disassembled, the screwing part 22 and the bolt head can realize automatic direction matching (namely, when the screwing mechanism is slowly rotated, after the screwing part 22 and the bolt head are aligned, the screwing part 22 can be automatically sleeved on the bolt head under the action of the second elastic member 70, and on the other hand, in the screwing and unscrewing processes of the bolt, the driving mechanism 80 only needs to perform rotary motion, and under the action of the second elastic member 70, the screwing part 22 always presses on the bolt head, so that the screwing part 22 can automatically retract or advance, and the dismounting device and the bolt can be prevented from being separated due to the out-of-sync rotation and advance and retreat during operation.
Further, in the present embodiment, the fastener assembling and disassembling device includes a driving mechanism 80, and the driving mechanism 80 can be connected to the inner sleeve 50 for driving the inner sleeve 50 to rotate, so as to drive the screwing mechanism 20 to rotate. In some embodiments, the driving mechanism 80 may be a driving rod, which may be connected to the third extension 52 of the inner sleeve 50 by a fastening assembly, so as to allow the user to manually drive and rotate and apply elastic force to the second elastic member 70.
