Specifically, in this embodiment, the linkage assembly 17 includes a rotating shaft 171, a fixing member 172 and a limiting member 173, the fixing member 172 is fixedly disposed on the supporting seat 132 of the mounting seat 13, the rotating shaft 171 is rotatably and movably sleeved in the fixing member 172, an upper end of the rotating shaft 171 is pivotally connected to the pressing member 21, a lower end of the rotating shaft 171 is rotatably connected to the pushing member 15, a spiral guiding groove 17a is disposed on the rotating shaft 171 along a circumferential direction thereof, one end of the limiting member 173 is fixed on the supporting seat 132 of the mounting seat 13, and another end of the limiting member 173 is slidably engaged in the guiding groove 17 a. When the pushing member 15 linearly moves on the supporting seat 132 along the vertical direction to push the adapting shaft 171, the adapting shaft 171 can rotate and move relative to the fixing member 172 under the action of the pushing force provided by the pushing member 15 and the tangential force provided by the limiting member 173 and limited by the guiding groove 17a, so as to drive the pressing member 14 to linearly move, so as to release the pressing on the cap 203, and when the pushing member 15 moves in the opposite direction, the pressing on the cap 203 can be realized by the pressing member 14.

Preferably, the number of the fixing elements 172 may be two, and the two fixing elements 172 are disposed on the supporting seat 132 at intervals and sleeved on opposite ends of the adapting shaft 171, so that the movement of the adapting shaft 171 is more stable. The fixing member 172 is preferably a bearing, and may be a bushing, as long as it can realize a rotatable and movable connection with the rotating shaft, and the invention is not limited thereto. Of course, in other embodiments, the lower end of the adapting shaft 171 can be fixedly connected to the pushing member 15, so that the pushing member 15 can move linearly on the supporting seat 132 along the vertical direction to drive the adapting shaft 171 to move linearly up and down, thereby realizing the reciprocating motion of the pressing member 14. When the lower end of the transfer shaft 171 is movably connected to the pushing member 15 by a cam structure, the up-and-down movement of the transfer shaft 171 can be effectively controlled by the relative sliding between the transfer shaft 171 and the pushing member 15.

Specifically, the guide groove 17a includes a first straight groove 17a1, a second straight groove 17a2 and an arc-shaped groove 17a3 connected between the first straight groove 17a1 and the second straight groove 17a2, the first straight groove 17a1 and the second straight groove 17a2 are arranged in parallel and at a distance from each other along the axial direction of the adapting shaft 171, and the end of the retaining member 173 is inserted into the guide groove 17a in a clearance fit manner.

In addition, the closed ends of the first straight groove 17a1 and the second straight groove 17a2 can also function as a stop for stopping the stopper 173 from moving further, so that the adaptor shaft 171 drives the pressing member 14 to be positioned at the set working position. As shown in fig. 6, the retaining member 173 is located at the closed end of the second straight groove 17a2, and the coupling shaft 171 is located at the upper limit position, so that the pressing member 14 is in the released pressing state without pressing the cap 203. As shown in fig. 7, the retaining member 173 is located at the closed end of the first straight groove 17a1, and the connecting shaft 171 is located at the lower limit position, so that the pressing member 14 is in the pressing state against the cap 203.

Referring to fig. 8 and 9, the linkage assembly 17 further includes a locking member 174 mounted on the mounting base 13, a locking portion 17b matched with the locking member 174 is disposed on the adapting shaft 171, and the locking member 174 can move linearly along the radial direction of the adapting shaft 171 to be clamped in the locking portion 17b or to be separated from the locking portion 17b, so as to limit or allow the movement and rotation of the adapting shaft 171. The locking portion 17b may be a slot hole formed on the lower sidewall of the adapter shaft 171, and of course, the locking portion 17b may also be an annular groove formed along the circumference of the lower sidewall of the adapter shaft 171, so as to simplify the structure and facilitate the engagement with the locking member 174. Wherein the end of the locking member 174 is an arcuate end. Specifically, in the present embodiment, a positioning element 175 is fixedly disposed on the supporting base 132, and the locking element 174 is telescopically sleeved with the positioning element 175 along the radial direction of the adapting shaft 171. Preferably, an elastic member 176 is connected between the locking member 174 and the positioning member 175, the elastic member 176 constantly drives the locking member 174 to move linearly in a direction of engaging with the locking portion 17b, and the elastic member 176 is a spring.

When the adapter shaft 171 rotationally moves linearly downward, the outer wall of the adapter shaft 171 abuts against the end of the locking member 174 to compress the elastic member 176, so that the locking member 174 contracts in the radial direction of the adapter shaft 171 to escape, so that the adapter shaft 171 moves downward continuously until the end of the limiting member 173 slides to the closed end of the first straight groove 17a1, the locking portion 17b of the adapter shaft 171 just rotates to be opposite to the locking member 174, the locking member 174 is engaged with the locking portion 17b under the restoring force of the elastic member 176, so that the adapter shaft 171 is limited from both ends to stop moving and rotating, and the pressing member 14 is kept in the state of abutting against the cap 203. When the adapter shaft 171 is driven by the pushing member 15 to rotate and move linearly upward, since the locking member 174 has an arc-shaped engaging end and the corresponding locking portion 17b also has a certain curvature, the elastic member 176 is compressed under the action of the pushing force, the locking member 174 can be disengaged from the engaging end of the locking portion 17b until the adapter shaft 171 moves until the end of the limiting member 173 slides to the closed end of the second straight groove 17a2, the pressing member 14 releases the pressing force on the cap 203, and the locking member 174 also moves outward to reset under the restoring force of the elastic member 176.

Further, an elastic member (not shown) may be disposed between the adapting shaft 171 and the mounting seat 13 or between the adapting shaft 171 and the fixing member 172, and the elastic member constantly drives the adapting shaft 171 to move linearly in a direction of engaging with the locking member 174. The elastic member is embodied as a spring.

Referring to fig. 6 and 8, the pushing element 15 is disposed at the edge of the mounting base 13, and specifically, is slidably disposed on the linear guideway 1321 of the supporting base 132. The pushing member 15 includes an abutting portion 151 located right below the adapter shaft 171, and the pushing member 15 slides on the linear slide rail 1321 so that the abutting portion 151 pushes the adapter shaft 171 from below the adapter shaft 171. Specifically, the abutting surface of the adapter shaft 171 abutting against the abutting portion 151 is a plane, and the abutting portion 151 has an arc end abutting against the adapter shaft 171, so that the abutting portion 151 only abuts against the adapter shaft 171 with the arc end, thereby effectively reducing the contact surface, providing a pushing force, reducing the friction force, and facilitating the rotation of the adapter shaft 171. In addition, in order to ensure the linear movement of the pushing member 15 in the vertical direction, the base 131 is further provided with a guide rod 1311, the guide rod 1311 is arranged in the vertical direction, and the pushing member 15 is arranged on the guide rod 1311 in a penetrating manner and can slide along the guide rod 1311, so that the stability of the linear movement of the pushing member 15 is further ensured. In order to facilitate pushing of the pushing member 15, the pushing member 15 further includes a pushing portion 152, and the pushing portion 152 is located at a side end of the pushing member 15 and extends beyond an edge of the mounting seat 13. Preferably, the pushing portion 152 may be formed by extending a side end of the pushing member 15 in a direction protruding from an edge of the supporting seat 132 or/and the base 131, so as to facilitate the operation.
