The handle 7 allows the pull rod 6 to move. A tension spring 8 is provided inside the cover plate 2, one end of the tension spring 8 being fixedly connected to the sliding plate 5, and the other end of the tension spring 8 being fixedly connected to the cover plate 2. The sliding plate 5 is connected by a tension spring 8, which provides tension. A guide rod 9 is slidably connected inside the sliding plate 5. The two ends of the guide rod 9 are fixedly connected to the cover plate 2. The sliding plate 5 is slidably connected to the cover plate 2, and the cover plate 2 is slidably connected to the slider 4. A sealing mechanism 10 is provided inside the cover plate 2. By pulling the slider 4, the slider 4 moves to a designated position. After the slider 4 moves to a designated position, the cover plate 2 moves the slider 4 and other components to a designated position on the housing 1. Then the slider 4 is moved into the slot 3, thereby limiting the cover plate 2 and other components, making it easy to install the housing 1 and the cover plate 2.

[0023] Please see Figure 5 The sealing mechanism 10 includes a screw 101. The screw 101 is threadedly connected to the inside of the cover plate 2. A rotating block 102 is fixedly connected to the upper end of the screw 101. The rotating block 102 contacts the cover plate 2. By designing the rotating block 102, the screw 101 can be driven to rotate. An annular sleeve 103 is rotatably connected to the outside of the screw 101. A bolt 105 is threadedly connected to the inside of the annular sleeve 103. An annular groove 104 is opened inside the screw 101. The bolt 105 is slidably connected inside the annular groove 104. By designing the bolt 105, the screw 101 and the annular sleeve 103 can be connected.

[0024] Please see Figure 3 , Figure 5 , Figure 6 The cover plate 2 has a connecting sleeve 106 slidably connected inside, which is fixedly connected to the annular sleeve 103. A guide block 107 is fixedly connected to the outside of the connecting sleeve 106. The cover plate 2 is slidably connected to the guide block 107. A guide rod 108 is slidably connected inside the guide block 107. Both ends of the guide rod 108 are fixedly connected to the cover plate 2. By designing the guide rod 108, the guide block 107 can be guided. A sealing sleeve 109 is fixedly connected to the lower end of the connecting sleeve 106. The sealing sleeve 109 contacts the cover plate 2 and the housing 1. By rotating the screw 101, the cover plate 2 undergoes threaded movement. The rotation of the screw 101 drives the sealing sleeve 109 to move downward. The sealing sleeve 109 moves downward and contacts the designated position of the housing 1, thereby sealing the connection between the housing 1 and the cover plate 2, making the device easy to use.

[0025] The specific implementation process of this utility model is as follows: Before the device is used, pull the handle 7 to move away from the cover plate 2. The movement of the handle 7 drives the pull rod 6 to move, the movement of the pull rod 6 drives the sliding plate 5 to move, the movement of the sliding plate 5 drives the slider 4 to move, and the movement of the sliding plate 5 stretches the tension spring 8. After the slider 4 moves to the designated position, the cover plate 2 is moved to move the handle 7 and the slider 4 and other components towards the housing 1. After the cover plate 2 and other components move to the designated position on the housing 1, the handle 7 is released. The tension of the tension spring 8 pulls the sliding plate 5 to move, and the movement of the sliding plate 5 drives the slider 4 and other components to move. After the slider 4 moves into the slot 3, the cover plate 2 and other components are limited, making it easy to install the housing 1 and the cover plate 2.

[0026] When the device is in use, rotating the rotating block 102 causes the screw 101 to rotate. The screw 101 rotates and makes threaded movement with the cover plate 2, which in turn causes the screw 101 to have relative displacement. The rotation of the screw 101 causes components such as the annular sleeve 103 to move downward. The downward movement of the annular sleeve 103 causes the guide block 107 and the sealing sleeve 109 to move downward. The sealing sleeve 109 moves downward and contacts the designated position of the housing 1, thereby sealing the connection between the housing 1 and the cover plate 2, making the device easy to use.
