[0024] The effect achieved by the entire embodiment 1 is that the setting of the sealing ring 7 can increase the sealing performance of the connection between the sealing cover 6 and the wellhead, and when the movable block 15 moves up and down in the column 4, the slide rod 17 and the compression spring 18 are forced to be in an extended or compressed state, and then the elastic force of the compression spring 18 can be used to forcefully push the movable block 15 upward, and the slider 16 is forced to slide in the slide groove 14, and at the same time, the connecting rod 5 pushes the sealing ring 7 and the sealing cover 6, and the user adjusts the sealing ring 7 to the position corresponding to the wellhead through the handle 8, thereby ensuring normal protection in the future.

[0025] Example 2, as Figures 1-4 As shown, one end of the compression spring 18 is fixedly connected to the bottom surface of the movable block 15, and the other end of the compression spring 18 is fixedly connected to the inner bottom of the column 4. A slide groove 14 is provided at the center of the front and rear inner surfaces of the column 4. The inner wall of the slide groove 14 is slidably connected to a slider 16 near the top position. The outer surface of the slider 16 is fixedly connected to the front and rear outer surfaces of the movable block 15. The outer surface of the movable block 15 is slidably connected to the inner surface of the column 4. The center of the outer surface of one side of the sealing ring 7 is fixedly connected to a connecting block 13. The outer surface of one side of the connecting block 13 is fixed near the top position. A fixed lock 12 is installed, the inner surface of the connecting block 13 is slidably connected to the outer surface of the sealing cover 6, the outer surface of the column 4 is located at the position of the insertion rod 2 and a first circular hole 3 is opened, the inner wall of the first circular hole 3 is slidably connected to the outer surface of the insertion rod 2, the outer surface of the insertion rod 2 passes through the outer surface of the movable block 15, a well body 9 is provided at the top center of the base 1, the outer surface of the well body 9 is slidably connected to the inner surface of the sealing ring 7, the inner surface of the well body 9 is fixedly connected to a support plate 10 near the top position, and a second circular hole 11 is opened at the front and rear positions on both sides of the top of the support plate 10.

[0026] The effect achieved by the entire embodiment 2 is that, through the setting of the slider 16 and the slide groove 14, the stability of the movable block 15 when sliding up and down can be improved, and through the mutual cooperation of the connecting block 13, the sealing cover 6 and the fixed lock 12, an anti-theft effect can be achieved, and in actual use, the column 4 will be fixedly connected to the outer surface of the well body 9.

[0027] Working principle: When the equipment needs to be repaired or operated, the fixed lock 12 is opened and the sealing cover 6 is opened by pulling the handle. After opening, the user pulls the handle 8 downward. At this time, the sealing ring 7, the sealing cover 6, the fixed lock 12 and the connecting block 13 are forced to move downward together, and the connecting rod 5 drives the movable block 15 to slide downward in the column 4, and the slider 16 slides in the slide groove 14. The slide rod 17 and the compression spring 18 are under pressure to change their own state. Then, when the sealing ring 7 is moved downward to a certain position, the sealing ring 7 can be separated from the wellhead. After the movement is completed, the user can insert the insertion rod 2 into the corresponding first circular hole 3. The insertion realizes the restriction of the movable block 15 to avoid Subsequently, it will slide in the column 4, and at the same time it can also restrain the compression spring 18, so that it is always in a compressed state. Through the cooperation of multiple people, it is convenient for the user to inspect or operate the detection-related equipment at the wellhead. After the inspection or operation is completed, the user pulls out the insertion rod 2, and the compression spring 18 loses its restraint. Its elastic force is used to force the movable block 15 to slide upward, and the connecting rod 5 drives the sealing ring 7 and the sealing cover 6 to move upward. After the user adjusts the sealing ring 7 to the position corresponding to the wellhead through the handle 8, the insertion rod 2 is inserted into the first circular hole 3 to restrict the movable block 15, and at the same time indirectly ensures that the sealing ring 7 can be stably located at the wellhead to play a protective role.
