Further, in an embodiment, a mounting hole 224 is formed on a side wall of the plunger chamber 22 away from the fifth link 56, the mounting hole 224 is disposed radially toward the plunger chamber 22, an adjusting member 226 axially adjustable along the mounting hole 224 is disposed in the mounting hole 224, and the second elastic element 59 is disposed between the second hinge shaft 562 and the adjusting member 226 in a pulling manner. Specifically, the mounting hole 224 is a threaded hole, the adjusting member 226 is a bolt, etc., and when the position of the adjusting member 226 in the mounting hole 224 is adjusted, the tensile elastic force of the second elastic member 59 can be adjusted, so that the initial position of the cylinder 42 can be adjusted. The locking force between the upper cover 20 and the base 30 at the initial position can also be adjusted. When the adjusting member 226 moves away from the plunger chamber 22, the second elastic member 59 is elongated, and the locking force between the upper cover 20 and the base 30 becomes large when locking.

Further, in an embodiment, the upper cover 20 is further provided with a closed accommodating chamber 228, an end of the plunger chamber 22 away from the base 30 is communicated with the accommodating chamber 228, and the third link 52, the fourth link 54, the fifth link 56, the crank 586 and the second elastic element 59 are all located in the accommodating chamber 228; one end of the third link 52 extends to the plunger chamber 22 and is hinged with one end of the cylinder 42 away from the base 30; one end of the fourth link 54 is hingedly connected to an end of the receiving chamber 228 remote from the base 30. The accommodating chamber 228 is configured to accommodate the third link 52, the fourth link 54, the fifth link 56, the crank 586, the second elastic element 59, and the like, so that the third link 52, the fourth link 54, and the fifth link 56 have a larger swing range, and therefore, a locking force is larger during locking, and the locking or unlocking is less prone to being locked. In actual production, since the upright 12 and the like are mounted on the upper cover 20, the upright 12 and the upper cover 20 may be integrally formed or may be connected by a connecting member such as a screw. Therefore, it is possible for the receiving chamber 228 and a portion of the plunger cavity 22 to extend into the column 12, and this is within the scope of the present invention. When the upper cover 20 has a sufficient space, the accommodation chamber 228 and the plunger chamber 22 may be completely provided in the upper cover 20.

Further, in one embodiment, the end of the column 42 near the base 30 is embedded with rubber. The column body 42 contacts with the base 30 through rubber, when the column body 42 props against the base 30, as the static friction force between the rubber and the base 30 is larger, when the static friction force is larger, the locking force is larger, and the locking effect is better. Preferably, the column 42 includes a housing 426 with a downward opening, the housing 426 is filled with a second rubber block 428, and the second rubber block 428 is made of a rubber material with a relatively high friction coefficient, so that the locking effect between the upper cover 20 and the base 30 is better. The second rubber block 428 covers the bottom of the housing 426, and when the column 42 contacts the base 30, the second rubber block 428 contacts the base 30 completely, so that the locking effect between the upper cover 20 and the base 30 is better.

Referring to fig. 9 to 10 again, in fig. 9, the handle body 584 is not pressed, and the cylinder 42 is pressed down by the second elastic element 59, so that the upper cover 20 and the base 30 are locked. In fig. 10, the handle body 584 is pressed, the second elastic member 59 is extended, the column 42 is lifted, and the locking of the upper cover 20 is released, which is convenient to operate and simple in structure.
