The first and second mounting

parts

120 and 220 are disposed perpendicular to the guide 300, such that the first and second mounting

parts

120 and 220 are disposed in parallel. Meanwhile, the distances from the first mounting hole and the second mounting hole to the guide 300 are the same, so that the rotation center of the ratchet wrench 110 and the axis of the fixing sleeve 210 can be overlapped, and the ratchet wrench 110 and the fixing sleeve 210 can be accurately sleeved on a bolt and a nut to be screwed.

The reset member 400 may be specifically configured as a spring, an electric push rod, an air cylinder, or other power elements, as long as the first mounting portion 120 and the second mounting portion 220 can be driven to approach each other.
