[0030] Specifically, the movement of the slide groove 4 can cause the second mounting plate 5 to move forward and backward. When the motor 7 is started, the rotating rod 8 and the first bevel gear 9 thereon will rotate. Through the meshing transmission, the second bevel gear 10 and the threaded rod 11 thereon will also start to rotate. In this way, the rotation of the threaded rod 11 will cause the cushion 12 to move forward and backward to fix the electromagnetic reversing valve 20. By using the fixing plate 1, the device can be easily installed.

[0031] Reference Figure 1 and Figure 3The sealing mechanism 2 includes a plurality of first connecting pipes 201, which are respectively arranged on the left and right sides of the outer wall of the electromagnetic reversing valve 20, and the outer side of the first connecting pipe 201 is threadedly connected with the second connecting pipe 205, and the bottom of the second connecting pipe 205 and the top of the first connecting pipe 201 are both provided with a sealing groove 202, and the inner side of the sealing groove 202 is fixedly connected with a sealing gasket 203, and the inner side of the sealing gasket 203 is fixedly connected with a filter screen 204;

[0032] Specifically, by engaging the sealing gasket 203 with the internal filter 204 and the sealing groove 202, and by fixing the first connecting tube 201 and the second connecting tube 205, the sealing performance of the electromagnetic reversing valve 20 can be improved. This design can not only filter the fluid or gas passing through it, but also make it easy to remove the sealing gasket 203 to replace the filter 204.

By installing a threaded part in the positioning hole 14 outside the positioning block 13, the convenience of installing the fixed plate 1 can be further improved. The plug-in rod 15 can facilitate the plug-in installation of the fixed plate 1. The protective pad 16 can prevent wear on the electromagnetic reversing valve 20 when it is fixed.

[0037] Working principle: Before using the device, first, the movement of the slide groove 4 can make the second mounting plate 5 move forward and backward.

The rotation of the threaded rod 11 causes the cushion 12 to move forward and backward to fix the electromagnetic reversing valve 20. The entire device can be easily installed through the fixing plate 1. At the same time, it also provides protection and fixation for the electromagnetic reversing valve 20, reducing the possibility of vibration or displacement during operation to reduce the probability of leakage, thereby improving the reliability of the device, and engaging the sealing gasket 203 with the inner filter screen 204 and the sealing groove 202, and by fixing the first connecting pipe 201 and the second connecting pipe 205, the sealing performance of the electromagnetic reversing valve 20 can be improved.
