The end of the piston rod 4 near the baffle 6 is fixedly connected to a telescopic cylinder 5. The telescopic cylinder 5 is composed of multiple telescopic cylinders with different radii, which can accommodate shaft pins of different sizes. When a shaft pin is inserted into a cylinder, cylinders smaller than the diameter of the shaft pin will be compressed back. The hydraulic pump 2 is connected to an external oil tank through a pipe.
[0024] A baffle 6 is fixedly connected to the upper surface of the base 1 at the end away from the support plate 14. The side surface of the baffle 6 has a groove. An upper clamping plate 7 is slidably connected to the side end of the baffle 6. The upper clamping plate 7 also has a groove at its side end. The upper clamping plate 7 slides on the baffle 6 through the groove, which is a cross-shaped groove. A second bolt 25 is rotatably connected to the end of the upper clamping plate 7 away from the support plate 14. The connection position of the second bolt 25 has threads. The second bolt 25 approaches the baffle 6 through the threaded through hole, clamping the protruding part of the groove, thereby pressing the upper clamping plate 7 tightly against the baffle 6.

The hydraulic cylinder 3 generates thrust under the action of the oil, pushing the piston rod 4 to extend and pushing the telescopic cylinder 5 to move. After inserting the shaft pin into the oil distribution plate, turn off the motor 23.
