[0031] The extrusion assembly 61 includes a first fixed plate 611, which is fixedly connected to the surface of the slide 4 in a left-right symmetrical manner. A sloped block 612 is provided on the side of the first fixed plate 611 close to the inner wall of the box body 1. The sloped block 612 is fixedly connected to an arc block 613 on the side of the inner wall of the slide 4. An anti-slip pad 614 is fixedly connected in the concave groove of the arc block 613. An L-block 615 is fixedly connected to the bottom of the slide 5 in a left-right symmetrical manner.

[0032] A hole matching the slide 4 is provided at the bottom of the box body 1 , and the surface of the slide 4 passes through and is connected to the hole by sliding up and down.

[0033] A groove matching the inclined surface block 612 is provided on the first fixing plate 611 close to the inner wall of the box body 1 and the surface of the slide 4, and the inclined surface block 612 passes through and is slidably connected in the groove. The other end of the L block 615 is inclined and corresponds to the inclined surface of the inclined surface block 612.

[0034] The moving component 62 includes a bearing 621, which is arranged at the top of the box body 1. The inner ring of the bearing 621 is fixedly connected to a screw 622, the surface of the screw 622 is threadedly connected to a rotating frame 623, the bottom of the rotating frame 623 is fixedly connected to a fixed rod 624, the top of the box body 1 is fixedly connected to a motor 625, the output end of the motor 625 is fixedly connected to a worm 626, and the surface of the screw 622 near the top is fixedly connected to a worm gear 627.

[0035] A hole matching the bearing 621 is provided on the top of the box body 1, and the outer ring of the bearing 621 passes through and is fixedly connected to the hole. The bottom end of the fixed rod 624 is fixedly connected to the top of the slide 5. The slide 5 limits the rotating frame 623 so that the rotating frame 623 can only move up and down with the rotation of the screw 622, and the worm 626 is engaged with the worm wheel 627.

[0036] Example 2

[0037] See also Figure 6 On the basis of the first embodiment, the rebound mechanism 7 includes a second fixed plate 71, which is fixedly connected to the surface of the slide 4 in a bilaterally symmetrical manner. The top of the inclined block 612 is fixedly connected to a third fixed plate 72 on the side close to the inner wall of the box body 1, and the third fixed plate 72 is fixedly connected to the side away from the inner wall of the box body 1. A spring 74 is sleeved on the surface of the guide rod 73 between the second fixed plate 71 and the third fixed plate 72.

[0039] In actual operation, when using this device, the support leg 2 of the device is placed on the surface of the equipment to be taken out of the pin shaft. At this time, the pin shaft is located in the slide cylinder 4 and between the two arc blocks 613. Then, the motor 625 is started to rotate the worm 626. The rotation of the worm 626 will rotate the worm wheel 627. The rotation of the worm wheel 627 will rotate the screw 622, thereby driving the rotating frame 623 and the fixed rod 624 to move upward, further driving the slide plate 5 to move upward, and the slide plate 5 will drive the two L blocks 615 upward. When the L block 615 moves upward, it squeezes the two inclined blocks 612, causing the two inclined blocks 612 to move toward each other, thereby causing the two arc blocks 613 to move toward each other to clamp the pin. When the two inclined blocks 612 tightly clamp the pin, the upward movement of the slide plate 5 drives the slide cylinder 4 to move upward, thereby driving the pin clamped by the two arc blocks 613 to move upward, thereby removing the pin. This process can replace manual labor to easily remove the pin, saving manpower and improving work efficiency.

[0040] After the pin is taken out, the motor 625 is used to rotate the screw 622 in the opposite direction, so that the rotating frame 623 and the fixed rod 624 move downward, thereby moving the slide plate 5 downward, and further moving the two L blocks 615 downward, releasing the squeezing force on the inclined block 612, and the two inclined blocks 612 will move in opposite directions toward each other due to the elastic force of the spring 74, releasing the clamping force on the pin.
