Abstract
Provided is a bit attachment device comprising an attaching sleeve, a disassembling-attaching assembly and an abutting assembly arranged in sequence. A first end of the attaching sleeve is attached to a movable rod within the tightening module via a buffer assembly to synchronize movement with the movable rod. A first end of an attaching shaft of the disassembling-attaching assembly forms a tight fit with a second end of the attaching sleeve via a spline structure, and the second end is attached to a bit. The abutting assembly is movably provided at a position on an outer periphery of the second end of the attaching sleeve, so that it can abut against the attaching shaft in a radial direction or move away from the attaching sleeve to loosen the attaching shaft, and with the buffer assembly, mitigate the impact force of the structure to be locked when the bolt is installed.
