Abstract
The application belongs to the technical field of pin dismounting, and particularly relates to a pin dismounting tool, which comprises a mounting bracket, a telescopic mechanism and a connecting rod, the mounting bracket is used for being fixed to a pin component to be dismounted, the telescopic mechanism is connected to the mounting bracket, the connecting rod comprises a rod body, a rotating part and a screwing part, two ends of the rod body are respectively connected with the rotating part and the screwing part, the screwing part is used for being screwed with a threaded hole of the pin, and the rotating part is rotationally connected with the telescopic mechanism, so that the connecting rod can rotate around its own axis; the telescopic mechanism is used for driving the connecting rod to move back and forth along its own axis, and an operator can realize the dismounting of the pin by rotating the connecting rod and starting the telescopic mechanism, which saves time and labor in the dismounting operation, meanwhile, the connecting rod will not contact other parts of the pin component to be dismounted, damage to the pin component to be dismounted is reduced, and the maintenance efficiency of the pin component to be dismounted is improved.
