[0018] By Figures 1-4 The utility model discloses a base 1, mounting frame 5 and pump body 7 are given, mounting frame 5 is placed on the top of base 1, two support frames 6 are fixedly installed on the top of mounting frame 5, and the pump body 7 is fixedly installed on the two support frames 6, and the support column 2 is fixedly installed on the top of base 1 and is located at the bottom of four corners of mounting frame 5, the butt joint groove 3 is seted up on the top of four support columns 2, the screw groove 4 is seted up on the bottom of four butt joint grooves 3, the butt joint block 9 is fixedly installed on four corners of mounting frame 5 bottom, the second screw hole 10 that passes through up and down is seted up on every butt joint block 9, the first screw hole 8 is seted up on four corners of mounting frame 5, and four butt joint blocks 9 of mounting frame 5 bottom can be placed in the butt joint groove 3 on the top of four support columns 2, and the bolt 11 is screwed in every first screw hole 8, and the bolt 11 passes through first screw hole 8 and second screw hole 10 in turn and is screwed in the corresponding screw groove 4.
[0019] As Figure 2 , Figure 3 and Figure 4As shown, four side walls of each docking groove 3 are provided with grooves 12, four through holes 13 are uniformly provided in the side walls of each support column 2 and communicate with the corresponding grooves 12, a top rod 15 is movably inserted in each through hole 13, one end of each top rod 15 located in the groove 12 is fixedly installed with a limiting block 14, a first spring 16 is fixedly connected between each limiting block 14 and the inner wall of the corresponding groove 12, four limiting grooves 17 are provided in the four side walls of each docking block 9, and the four limiting blocks 14 in each docking groove 3 are clamped in the four limiting grooves 17 in the side walls of the corresponding docking block 9. When the docking rack 5 is mounted with the support column 2, first hold the sleeve ring 18 on the support column 2 and make it move downward, the sleeve ring 18 will extrude the second spring 19 at the bottom, then make the four docking blocks 9 at the bottom of the rack 5 embedded in the four docking grooves 3 at the top of the four support columns 2, in this process, the bottom of the docking block 9 will extrude the spherical surface of the four limiting blocks 14, so that the limiting block 14 moves into the groove 12 and extrudes the first spring 16, when the docking block 9 is completely embedded in the docking groove 3, the first spring 16 in the groove 12 releases the elastic force to push the limiting block 14 to be clamped in the limiting groove 17 on the outer wall of the docking block 9, at this time, one end of the top rod 15 is flush with the outer wall of the support column 2, then release the sleeve ring 18 to make the second spring 19 release the elastic force to push it upward, in this way, under the action of the sleeve ring 18, the top rod 15 cannot move position.
[0020] As shown in Figure 1 and Figure 2 , the four support columns 2 are movably sleeved with sleeve rings 18, the second spring 19 is fixedly connected between the bottom of the four sleeve rings 18 and the top of the base 1, under the action of the second spring 19, the sleeve ring 18 can be located at the through hole 13 on the outer wall of the support column 2 without external force.
[0021] As shown in Figure 1 and Figure 2 , when the limiting block 14 is clamped in the limiting groove 17, one end of the top rod 15 away from the limiting block 14 is flush with the outer wall of the support column 2, when the second spring 19 is in the normal state, the position of the sleeve ring 18 is located at the through hole 13 on the outer wall of the support column 2, in this way, the inner wall of the sleeve ring 18 can resist the top rod 15 to make it unable to move position, thereby completing the clamping of the limiting block 14 and the limiting groove 17.
[0022] As shown in Figure 2 and Figure 3 , the docking groove 3 and the docking block 9 are both square, and the limiting block 14 and the limiting groove 17 are both semispherical, when the spherical limiting block 14 is extruded, it is easier to move into the groove 12, in this way, the docking block 9 can be more smoothly embedded in the docking groove 3 at the top of the support column 2.
[0023] As shown in Figure 1and Figure 2 As shown, the four feet at the bottom corners of the mounting frame 5 are provided in a cylindrical shape, and the diameter of the feet is the same as that of the support column 2, and the inner ring wall of the sleeve ring 18 is in close contact with the outer wall of the support column 2, so that the sleeve ring 18 can play a role in position constraint on the ejector rod 15 in the through opening 13, so that the ejector rod 15 cannot extend out of the through opening 13, thereby allowing the limiting block 14 screwed at one end of the ejector rod 15 to be stably clamped in the limiting groove 17 of the side wall of the butt block 9.
