[0034] In this embodiment, during use, the top cover 106 at the top of the tube sleeve body 1 provides a dust-proof effect. At the same time, the inner tube sleeve 104 is connected through the connecting member 103, and the limiting plate 1047 on the inner wall is fixed by the inner tube sleeve 104. When the moving ring 1043 is connected to one end of the solenoid valve, both ends of the damper 1046 of the second spring 1045 are respectively connected to the surfaces of the limiting plate 1047 and the moving ring 1043, thereby performing shock absorption work on the solenoid valve, enabling the moving ring 1043 to slide on the outer surface of the guide rod 1042. Since the guide rod 1042 is fixedly installed on the inner wall of the notch 1041, the moving ring 1043 is limited to prevent tilting of the position during operation. At the same time, it works in cooperation with the heat dissipation ribs 102 and the heat dissipation fan 1031 to dissipate heat inside the tube sleeve body 1, preventing the internal temperature from being too high and affecting the service life of the parts.

At the same time, the installation ring 1071 is sleeved on the outer surface of the bushing body 1. When the thread ring 1051 on the surface of the thread groove 105 is rotated, the thread ring 1051 is driven to move on the outer surface of the bushing body 1. When the thread ring 1051 contacts the installation ring 1071, the installation ring 1071 is moved.

The guide rod 1042 is fixedly installed on the inner wall of the notch 1041 to limit the moving ring 1043 and prevent it from tilting during operation. At the same time, it works in cooperation with the heat dissipation ribs 102 and the heat dissipation fan 1031 to dissipate heat inside the sleeve body 1 and prevent the internal temperature from being too high, which affects the service life of the parts. In addition, the mounting ring 1071 is fixed by the first spring 107 on the surface of the sleeve body 1, and the mounting ring 1071 is sleeved on the outer surface of the sleeve body 1. When the threaded ring 1051 on the surface of the threaded groove 105 is rotated, it drives the threaded ring 1051 to move on the outer surface of the sleeve body 1. When the threaded ring 1051 contacts the mounting ring 1071, the mounting ring 1071 moves, and at the same time, the inclined block 1072 on the inner wall moves inside the limiting groove 101 to connect with the parts on the surface of the solenoid valve and provide a limiting effect.
