In this embodiment, the first limiting portion 33 is a circular ring structure, and the outer diameter of the first limiting portion 33 is larger than the diameter of the first opening 11 and smaller than the outer diameter of the first step 12, so that the first limiting portion 33 cannot pass through the first opening 11, and the first limiting portion 33 can abut against the first step 12. The second limiting portion 34 is a block structure, and the number of the second limiting portions 34 is two; accordingly, two avoidance spaces 121 are provided on the first step 12, and the shape of the avoidance spaces 121 is adapted to the shape of the second limiting portion 34. The second limiting portion 34 can reach the lower surface of the first step 12 by passing through the avoidance spaces 121, thereby realizing the installation of the knob member 3, which is in line with actual production.

[0037] In order to limit the rotation range of the knob member 3, a moving portion 35 is provided on the side of the knob base 31, and two limiting portions 13 are provided on the lower surface of the first step 12. The moving portion 35 is located between the two limiting portions 13, and the moving portion 35 cannot cross the limiting portion 13, thereby limiting the rotation range of the knob member 3. Among them, the angle between the two limiting portions 13 is a right angle, that is, the rotation range of the knob member 3 is 90°. Preferably, the two second limiting portions 34 and the limiting portion 13 are rotationally symmetrically distributed around the axial direction of the knob base 31, and the relevant structures are distributed accordingly to improve the reliability of the knob member 3.

[0038] In order to relatively fix the knob member 3 in the position, each stopper 13 is equipped with a locking portion 14, and the stopper 13 and the locking portion 14 are arranged adjacent to each other, so that a locking position is formed between the stopper 13 and the locking portion 14; the spacing between the stopper 13 and the locking portion 14 is adapted to the width of the movable portion 35, and the movable portion 35 can cross the locking portion 14 and enter the locking position.

When the active member 51 rotates, the sliding part 524 moves along the inclined surface 515, causing the upper and lower positions of the sliding part 524 in the axial direction to change, thereby changing the axial position of the passive base 521, and then driving the bottom cover body 2 to change in the axial direction. See. Figure 6 and 7 When the sliding portion 524 is at a higher point of the inclined surface 515, the passive base 521 is in an axially upper position, that is, the bottom cover body 2 is in an axially upper position, and under the pressure of the edge of the surface cover body 1, the sealing member 4 is tightly attached to the inner wall of the container body to achieve sealing. At this time, the knob-type sealing cover is in a closed state; when the sliding portion 524 is at a lower point of the inclined surface 515, the passive base 521 is in an axially lower position, that is, the bottom cover body 2 is in an axially lower position, and the pressure of the edge of the surface cover body 1 is lost, and the sealing member 4 is no longer pressed against the inner wall of the container body. At this time, the knob-type sealing cover is in an open state.

[0044] In the present embodiment, the active transmission part 514 is a cylindrical structure so that the inclined surface 515 is arranged around the axial direction of the active component 51. The lower surface of the sliding part 524 is an arc surface, and the width of the sliding part 524 is adapted to the width of the inclined surface 515. The number of inclined surfaces 515 is set to three, and the three inclined surfaces 515 are rotationally symmetrically distributed around the axial direction of the active base 511. Correspondingly, the number of sliding parts 524 is set to three, and the sliding parts 524 correspond to the inclined surfaces 515 one by one. In this way, the force between the active component 51 and the passive component 52 is evenly distributed, and the transmission is more reliable and stable. Among them, a slope 516 is set on the outer peripheral surface of the active base 511, and the surface of the slope 516 constitutes the inclined surface 515.

[0045] In order to maintain the contact connection between the sliding part 524 and the inclined surface 515, an elastic member 53 is provided between the knob base 31 and the passive base 521. The passive base 521 maintains the contact connection with the active base 511 under the force provided by the elastic member 53. In this embodiment, the elastic member 53 is a spring.
