[0024] As mentioned above, when the equipment is working, the electric push rod 2 above the bracket 101 is started, and the electric push rod 2 pushes the lifting rod 201 downward. Since one end of the connecting rod 1 302 is connected to the bracket 101, and the other end is connected to the slider 301, the sliders 301 at both ends move toward the middle, and the connecting rod 2 303 connected to the other side of the slider 301 rotates accordingly, driving the clamping rod 304 at the other end of the connecting rod 2 303 to slide in the support block 1011 and move toward the middle of the placement table 4. The clamping block 305 at the bottom end of the clamping rod 304 moves accordingly to clamp the pump body placed on the placement table 4.

[0025] The rear end of the clamping block 305 is provided with three sockets 3051, and the corresponding positions at the bottom end of the clamping rod 304 are also provided with holes. After the insertion rod 306 is inserted into the sockets 3051, a nut is installed to fix it. A pull ring is provided on the top of the insertion rod 306, and a rubber pad 3052 is pasted on the clamping surface of the clamping block 305.

[0026] As mentioned above, after the socket 3051 of the clamping block 305 to be used is matched with the hole at the bottom end of the clamping rod 304, the plug rod 306 is inserted and a nut is installed at the end to fix it. Three sockets 3051 are set to facilitate the adjustment of the distance between the clamping blocks 305 at both ends according to the size of the pump body. A pull ring is set at the top of the plug rod 306 to facilitate the operation of the plug rod 306. A rubber pad 3052 is pasted on the clamping surface of the clamping block 305, which can make the clamping more firm and not easy to slide, and also increase the buffer to reduce damage to the clamped object.

A limiting plate 402 is fixed on one side of the placement table 4, and a direction is limited when the pump body is placed, so that the pump body can be placed quickly and neatly, thereby improving work efficiency. A non-slip coating is applied to the surface of the placement table 4 and the limiting plate 402 to increase the anti-slip property and prevent the pump body from moving.

[0029] Two springs 307 are connected between the clamping rod 304 and the bracket 101 , and a control panel 5 is installed on the top of the base 1 .

[0030] As mentioned above, a spring 307 is provided between the clamping rod 304 and the bracket 101 to increase the buffer and reduce the damage to the pump body caused by excessive clamping of the clamping block 305. A control panel 5 is provided on the top of the base 1 to control the working condition of the equipment, to operate intuitively and to make timely adjustments.

[0031] Working principle: Before the equipment works, place one side of the pump body against the side wall of the limit plate 402, select the appropriate socket 3051 according to the size of the pump body, use the plug 306 to fix the clamping block 305 at the bottom of the clamping rod 304, and then rotate the screw 401 according to the size of the pump body, adjust the placement table 4 to a suitable height, start the electric push rod 2 above the bracket 101, and the electric push rod 2 pushes the lifting rod 201 downward, and the connecting rod 1 302 drives the slider 301 to move toward the middle, and the connecting rod 2 303 connected to the other side of the slider 301 rotates accordingly, driving the clamping rod 304 at the other end of the connecting rod 2 303 to slide in the support block 1011 and move toward the middle of the placement table 4, and the clamping block 305 at the bottom of the clamping rod 304 moves accordingly to clamp the pump body placed on the placement table 4.
