[0004] During the operation of the above-mentioned device, the electromagnetic water pump is protected by the protective shell, and the protective top cover is detachable and used in conjunction with the shock-absorbing structure for shock absorption. However, it is easy to cause rough misalignment of the entire device during use, especially when used in a small working position. Large deviations can easily cause damage to the device and make it unable to operate, which can easily damage the electromagnetic water pump, making it inconvenient to quickly disassemble and repair it.

[0005] In addition, in the prior art, the authorization publication number CN216044384U is “an electromagnetic water pump fixing device that is easy to maintain”, in which the utility model discloses an electromagnetic water pump fixing device that is easy to maintain, comprising a fixing base, a fixing mounting frame, a protective shell and an electromagnetic water pump, the fixing mounting frame being installed on the top of the fixing base, the protective shell being provided on the fixing base, the electromagnetic water pump being provided in the protective shell, a water suction pipe being provided at one end of the electromagnetic water pump, and the water suction pipe passing through the protective shell and extending out from one side of the protective shell, the electromagnetic water pump being provided with a water outlet pipe, and the water outlet pipe passing through the protective shell and extending out from one side of the top of the protective shell; the beneficial effect of the utility model is that the protective shell and the electromagnetic water pump are convenient to install and disassemble, and the electromagnetic water pump is easy to maintain and repair in the later stage, and the impact force can be effectively shock-absorbing and buffered, thereby protecting the water pump, preventing the water pump from being damaged, and prolonging its service life; the heat dissipation is carried out through the heat dissipation through-hole and the heat dissipation fan, so that the air inside the protective shell flows, thereby improving the heat dissipation effect and preventing the device from being damaged by overheating;

[0006] During the operation of the above device, the electromagnetic water pump is fixed by the action of fixing bolts and buffer springs, which is convenient for installation and disassembly, as well as subsequent maintenance and repair.

[0034] 4. The micro electromagnetic water pump, which is easy to repair, position and assemble, is provided with a moving block that is easy to adjust elastically, which effectively controls the positioning column to engage and position the retaining frame. During maintenance, the handle can be rotated to control the adjusting rod to drive the moving rod to rotate, thereby squeezing the moving block on the support rod, effectively squeezing the reset spring 2, and disengaging the positioning column from the retaining frame to prevent it from falling off, while also facilitating disassembly and maintenance of the device.

[0048] The built-in strip 2 is embedded in the outer surface of one set of shells 1 and forms a built-in nested structure with another set of shells 1 , and the shells 1 , the limiting strip 3 and the positioning pin 5 form an integrated structure.

[0049] The outer surface of the limit bar 3 is slidably connected to the slide 301, and the inner surface of the slide 301 is installed with an elastic sheet 302, and the inner surface end of the elastic sheet 302 is installed with a clamping block 303, and the outer surface of the elastic sheet 302 is installed with an unlocking piece 304, and the outer surface of the unlocking piece 304 is nested with a return spring 305, and the return spring 305 is connected to the outer surface of the elastic sheet 302 and the inner surface of the slide 301.
