Safe and reliable pressing device for pin shaft machining

The utility model discloses a safe and reliable pressing device for pin shaft machining, belongs to the technical field of pin shafts, and aims to solve the problems that in the existing pin shaft machining process, a pin shaft needs to be pressed and fixed, only pin shafts with fixed sizes and models can be pressed and machined generally in a traditional pressing and fixing mode, and convenience is reduced. Comprising a supporting table, a front-back penetrating containing channel is formed in the side wall of one side of the supporting table, the containing channel is of an arc-shaped structure, symmetrically-arranged supporting plates are fixed to the side wall of the top end of the supporting table, and sliding plates are slidably connected to the side walls of the sides, close to each other, of the supporting plates; through cooperation of the pressing plate, the placing channel, the guide plate, the sliding plate and the supporting plate, pin shafts of different sizes can be rapidly placed and pressed,
