Detailed Description

A loose joint assembly and disassembly tool comprises a handheld handle device 14 and an open ratchet wrench device 15, wherein a power switch 12 of the handheld handle device 14 is connected with a power supply 16 to control the power supply of the loose joint assembly and disassembly tool. The joint of the hand-held handle device 14 and the open ratchet wrench device 15 is a rotatable structure, and second fixing screws 13 are distributed around the circumference and used for stabilizing the connection of the hand-held handle device 14 and the open ratchet wrench device 15. The rotor 18 is arranged on one side of the head of the handle device 14, the forward and reverse rotation knob 17 is arranged on the other side of the head, the forward and reverse rotation knob 17 controls the clockwise rotation and the anticlockwise rotation of the rotor 18, the rotor 18 is inserted into the input pinion 1, and the input pinion 1 is driven to rotate when the power supply 16 supplies power.
