In this embodiment, in order to facilitate pulling the extending portion 2203 upwards, further, the outer surface of the telescopic rod 16 is movably sleeved with the sliding cylinder 19, the sliding cylinder 19 is located between the extending portion 2203 and the connecting plate 15, when the sliding cylinder 19 is pulled upwards, the sliding cylinder 19 pushes the extending portion 2203 to move upwards together, and therefore convenience in operation can be improved.

In this embodiment, because the telescopic link 16 is movably inserted into the connecting rod 7, it is required to ensure that the telescopic link 16 is not separated from the connecting rod 7, for this purpose, the outer surface of the telescopic link 16 is provided with a plurality of sliding grooves 17, movable balls 20 corresponding to the sliding grooves 17 one by one are movably embedded in the connecting rod 7, the movable balls 20 are located at positions of the connecting rod 7 close to the bottom, and the movable balls 20 are arranged circumferentially, the outer surface of the connecting rod 7 is screwed with a half-threaded pipe 18, the first half of the inner wall of the half-threaded pipe 18 has internal threads, the lower half is a smooth surface, when the half-threaded pipe 18 is rotated, the movable balls can move up and down along the connecting rod 7, when the half-threaded pipe 18 moves down, the lower half of the inner wall of the half-threaded pipe 18 will extrude each movable ball 20, the smooth surface of the lower half can smoothly extrude the movable balls 20, after the movable balls 20 are extruded, the movable balls move into the sliding grooves 17 in the axis direction of the connecting rod 7, and rotation and movement in the horizontal direction of the telescopic link 16 are limited.

Through the structure, when the half-threaded pipe 18 extrudes the movable ball 20 into the sliding groove 17, even if the air outlet hole of the sealing cavity is not sealed, the telescopic rod 16 slides downwards, but under the action of the movable ball 20, when the telescopic rod 16 slides downwards to the top of the sliding groove 17 to be contacted with the movable ball 20, the movable ball 20 locks the sliding groove 17, so that the telescopic rod 16 cannot slide downwards continuously, and the purpose that the telescopic rod 16 cannot be separated from the connecting rod 7 is achieved;

moreover, because the plurality of movable balls 20 are respectively extruded into the sliding grooves 17, and the movable balls 20 cannot be separated from the sliding grooves 17 under the action of the half-thread pipe 18, the movable balls 20 can limit the telescopic rod 16 to rotate in the horizontal direction, and the stability of the telescopic rod 16 in the locking state can be further improved;

moreover, there is inevitably a gap between the outer surface of the telescopic rod 16 and the inner wall of the connecting rod 7, and when the telescopic rod 16 moves up and down, the outer surface of the telescopic rod 16 easily tilts and collides with the inner wall of the connecting rod 7, which not only hinders the up and down movement of the telescopic rod 16, but also causes the shaking of the telescopic rod 16. Under the action of the movable ball 20, when the telescopic rod 16 inclines, the outer surface of the movable ball 20 is abutted against the inner wall of the sliding groove 17, so that the collision between the outer surface of the telescopic rod 16 and the inner wall of the connecting rod 7 can be avoided; after the outer surface of the movable ball 20 abuts against the inner wall of the sliding groove 17, when the telescopic rod 16 continues to move up and down, the movable ball 20 rolls along the inner wall of the sliding groove 17, the friction force is small, and the telescopic rod 16 can be ensured to move up and down smoothly; meanwhile, a distance close to zero can be kept between the movable ball 20 and the inner wall of the sliding groove 17, so that the telescopic rod 16 can be prevented from shaking;

when the rotating half-threaded pipe 18 moves upwards to remove the extrusion of the movable ball 20, the telescopic rod 16 is pulled downwards continuously, the top of the sliding groove 17 extrudes the movable ball 20 outwards to separate the movable ball 20 from the sliding groove 17, and the sealing piston can be moved out of the sealing cavity by pulling downwards continuously, so that the sealing piston can be replaced more conveniently.

In this embodiment, when the telescopic rod 16 and the connecting rod 7 move relatively, the sealing piston needs to move in the sealing cavity, and in order to ensure the smoothness of the movement of the telescopic rod 16, the friction force between the sealing piston and the sealing cavity needs to be smaller.

In order to solve the above problems, still further, the sealing piston comprises an upper piston 27 and a lower piston 23 which are connected through an extrusion piece 26, the friction coefficient of the outer surface of the upper piston 27 is greater than that of the outer surface of the lower piston 23, an oil cavity 25 and an oil way 24 which are communicated are arranged in the lower piston 23, the oil way 24 is communicated with the outside, one end of the extrusion piece 26 is fixedly connected with the upper piston 27, the other end of the extrusion piece 26 is movably and hermetically inserted into the oil cavity 25 with the lower piston 23, the extrusion piece 26 comprises a long column body at the upper part and a flat column body at the lower part, namely, the long column body at the upper part of the extrusion piece 26 is fixedly connected with the upper piston 27, the flat column body at the lower part is positioned in the oil cavity 25, the long column body is movably and hermetically inserted into the lower piston 23, the side surface of the flat column body is in sliding fit with the inner wall of the oil cavity 25, the lubricating medium in the extrusion piece 26 can be in contact with the inner wall of the sealing cavity through the oil way 24, and the lubricating medium is lubricating oil.

When the telescopic rod 16 moves upwards, because the friction coefficient of the outer surface of the upper piston 27 is greater than that of the outer surface of the lower piston 23, the lower piston 23 moves upwards relative to the upper piston 27, in the stage that the upward thrust is smaller than the friction force between the upper piston 27 and the sealed cavity, the extrusion piece 26 and the upper piston 27 are static relative to the connecting rod 7, along with the upward movement of the lower piston 23, the extrusion piece 26 extrudes the lubricating medium in the oil cavity 25, the lubricating medium contacts with the inner wall of the sealed cavity through the oil path 24, and the friction force between the sealed piston and the sealed cavity can be greatly reduced after the lubricating medium is adhered to the inner wall of the sealed cavity.
