[0036] In a preferred embodiment of the present invention, the opening handle 12 is respectively provided on both sides of the opening spring 11 and the connecting shaft 13 , and the opening spring 11 is sleeved on the top of the connecting shaft 13 .

[0037] It should be noted that the opening member 10 includes an opening spring 11 and an opening handle 12. The opening spring 11 is sleeved on the top of the connecting shaft 13. One end of the opening spring 11 is fixedly connected to the top of the connecting shaft 13, and the other end is fixedly connected to the sealed end of the inner side of the limiting sleeve 20. The opening handle 12 is fixedly connected to the connecting shaft 13 and is slidably connected to the limiting groove 21. In this way, during operation, the index finger and middle finger clamp the bottom of the opening handle 12 on both sides of the limiting sleeve 20, and the thumb is located at the arc of the sealed end of the limiting sleeve 20. Then, the index finger and middle finger lift the opening handle 12 upward, and the thumb presses the sealing sleeve downward, which drives the connecting shaft 13 to move upward, squeezing the opening spring 11 between the connecting shaft 13 and the limiting sleeve 20. When the thumb is released, the opening spring 11 returns to its original position, driving the connecting shaft 13 to move downward.

[0038] The placement mechanism 3 includes a base 30 ; the base 30 is fixedly connected to the limiting sleeve 20 , a movable hole 34 is formed on the base 30 , and the movable hole 34 is slidably connected to the connecting shaft 13 .
