[0014] 1. In the utility model, through the provided pressing protection mechanism, the user sets the bearing sleeve to be processed on the limit column in turn. The limit column can prevent the bearing to be processed from shaking during pressing. With the provided turning handle, transmission rod, fixed support, damping spring and other components, when the bearing to be processed needs to be processed, the user turns the turning handle, and the turning handle drives the transmission rod to rotate the transmission plate. During the rotation of the transmission plate, the damping spring drives the limit ball to fit the side wall of the transmission plate. When the bearing to be processed rotates to the bottom of the pressing head, the damping spring drives the limit ball to enter the locking groove. At this time, the user feels the turning handle when driving the transmission plate to rotate. Resistance, at this time stop rotating, and then the user starts the pressing machine, the pressing machine drives the pressing head to descend, and there is no need to directly place the bearing to be processed on the bottom of the pressing head for pressing, which can avoid the risk of misoperation or accidental injury. Then the user continues to turn the handle to press the next bearing to be processed.
