In an embodiment of the present invention, as shown in fig. 5 and 6, the pressing block 13 is provided with a clamping groove 13a and at least two limiting ports 13b communicated with the clamping groove 13a, the clamping groove 13a has a notch facing the limiting groove, the notch extends along an outer wall of the pressing block 13 to a side of the pressing block 13 facing the bracket 11, and each limiting port 13b is communicated with the notch and extends toward the supporting block 12; at least part of the structure of each material clamping elastic sheet 131 is accommodated in a limiting opening 13b, one end of each material clamping elastic sheet 131, which is far away from the opening, is connected with the pressing block 13, and one side, facing the clamping groove 13a, of the free end of each material clamping elastic sheet 131 is provided with a clamping protrusion 1311; in the closed state, the container cover 4 is accommodated and retained in the retaining groove 13a, and each retaining protrusion 1311 abuts against and retains the outer wall of the container cover 4.
In this embodiment, the clamping groove 13a of the pressing block 13 is used for accommodating and limiting the single container cover 4, a notch is formed on one side of the clamping groove 13a facing the supporting block 12, the notch extends to one side of the pressing block 13 facing the supporting portion 111 along the outer wall of the pressing block 13, so that the notch of the clamping groove 13a is of an L-shaped extending opening structure, a lateral and lower avoiding space is provided for the container cover 4 to enter the clamping groove 13a through the notch of the clamping groove 13a, and when the pressing block 13 descends, the container cover 4 located in the limiting groove can smoothly enter the clamping groove 13a through the notch of the clamping groove 13 a.
The limiting opening 13b of the pressing block 13 is used for accommodating and limiting the clamping elastic sheets 131, the clamping elastic sheets 131 and the limiting openings 13b are arranged in a one-to-one correspondence mode, or at least two clamping elastic sheets 131 are arranged in one limiting opening 13b, and the limiting openings 13b are used for isolating and protecting the clamping elastic sheets 131 on one hand, so that the clamping elastic sheets 131 can be prevented from being deformed or damaged when being touched by mistake or collided by other parts; on the other hand, the deformation direction of the material clamping elastic sheet 131 is also restricted by the limiting ports 13b, so that the limiting ports 13b can more reliably clamp the container cover 4, and meanwhile, the problem that the material clamping elastic sheet 131 deforms laterally and is deformed, and cannot be elastically restored is solved, and the service life of the material clamping elastic sheet 131 is prolonged. Because the container cover 4 generally has a multi-layer annular protrusion structure on the outer circumferential wall of the container cover 4 in order to ensure the sealing performance when the container cover 4 is used for being combined with the container cover 4, at least one annular groove body is formed on the surface of the container cover 4, and the clamping protrusion 1311 on the material clamping elastic sheet 131 can be in limit fit with the annular groove body on the container cover 4, so that the container cover 4 can be clamped and fixed. The clamping protrusion 1311 on the clamping elastic sheet 131 can be arranged to be of a V-shaped structure, so that when the pressing block 13 is pressed down, the outer wall of the container cover 4 can slide along the surface of the clamping protrusion 1311 on the clamping elastic sheet 131, and the clamping protrusion 1311 is finally clamped into the annular groove body on the container cover 4, so that the container cover 4 can be automatically clamped through the clamping mechanism 1.
Optionally, a distance between the free end of each of the clip clips 131 and the notch is greater than or equal to 0.
In this embodiment, the distance between the free end of each clip spring 131 and the notch is greater than or equal to 0, so that the clip spring 131 does not protrude out of the notch of the slot 13a, and thus when the pressing block 13 pushes the supporting block 12, each clip spring 131 does not contact with the supporting block 12 and deform, thereby avoiding the problem that the container cover 4 falls off due to the fact that the container cover 4 cannot be stably clamped and fixed when the clip spring 131 contacts and deforms with the supporting block 12, and meanwhile, avoiding damage when the clip spring 131 contacts with the supporting block 12.
