[0026] The buckle assembly 9 includes a fixed box 10, a slide bar 11, an L-shaped buckle block 12, a second spring 13, a ramp block 14, a triangular block 15, a connecting rod 16 and a handle block 17. The inner surface of the fixed box 10 is fixedly connected to the slide bar 11, the outer surface of the slide bar 11 is slidably connected to the L-shaped buckle block 12, the outer surface of the L-shaped buckle block 12 is fixedly connected to the second spring 13, the lower end of the L-shaped buckle block 12 is fixedly connected to the ramp block 14, and the outer surface of the ramp block 14 is slidably connected to the triangular block 15. The side surface of the triangular block 15 is fixedly connected to the connecting rod 16, and the end of the connecting rod 16 away from the triangular block 15 is fixedly connected to the handle block 17. The inner surface of the buckle groove 18 is adapted to the L-shaped buckle block 12, and the inner surface of the limit buckle groove 19 is adapted to the L-shaped buckle block 12. The outer surface of the fixed box 10 is fixedly connected to the base body 1. There are two buckle assemblies 9 and they are distributed on the left and right. The second spring 13 is sleeved on the outer surface of the sliding rod 11, and the outer surface of the connecting rod 16 is slidably connected to the fixed box 10.

[0027] Working principle: When installing the liquid level switch 3, just insert the liquid level switch 3 along the placement groove 2, and continue to move downward after contacting the connecting plate 5. At this time, the first spring 4 is compressed, and the L-shaped buckle blocks 12 on both sides of the buckle assembly 9 are snapped into the buckle groove 18 through the action of the arc surface, and move toward each other along the slide bar 11, and at the same time compress the second spring 13. When the L-shaped buckle block 12 extends into the buckle groove 18 and corresponds to the limit buckle groove 19, under the action of the restoring force of the second spring 13, the L-shaped buckle blocks 12 on both sides will automatically snap into the limit buckle groove 19, completing the limit installation of the liquid level switch 3. When the liquid level switch 3 is damaged and needs to be replaced, just press the buckle assembly The handle block 17 on the component 9 drives the connecting rod 16 to drive the triangular block 15 to slide along the inclined surface of the inclined surface block 14, so as to drive the L-shaped buckle blocks 12 on the corresponding two sides to move toward each other along the slide rod 11, so that the end of the L-shaped buckle block 12 is separated from the inside of the limit buckle groove 19 to release the restriction on the liquid level switch 3. At this time, under the action of the restoring force of the first spring 4 in the compressed state, the connecting plate 5 will be pushed up along the guide rod 7 through the slider 6, thereby driving the liquid level switch 3 to move upward for a distance, so that the L-shaped buckle block 12 is completely separated from the inside of the buckle groove 18, simplifying the disassembly process and improving work efficiency. Then, the installation can be carried out by the above method, which is simple and convenient without the help of tools.

[0028] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
