When the cover opening operation is required, the user can apply a force to the pushing portion 63 to drive the second rod body 61 to swing, and in the swinging process of the second rod body 61, the third propping portion 64 located on the second rod body 61 props against the second propping portion 45 located on the first rod body 41 and overcomes the retaining force of the retaining member 50, so that the first locking hook 43 can be separated from the position (i.e. the hooking position) where the first locking hook 43 is hooked and matched with the second locking hook 30, and the user can perform the cover opening operation. The distance between the second pivot portion 62 and the third abutting portion 64 is larger relative to the distance between the first pivot portion 42 and the second abutting portion 45, and the distance between the push portion 63 and the third abutting portion 64 is smaller or equal relative to the distance between the first abutting portion 44 and the second abutting portion 45, so that the force arm is set more reasonably, a user can overcome the holding force of the holding piece 50 with smaller force, the uncovering operation of the user is more labor-saving, and the use of the user is facilitated. Therefore, the technical scheme of the embodiment can effectively solve the problem that a user in the related art needs to apply a larger acting force to the button.

Specifically, as shown in fig. 1 to 3, in the present embodiment, the second latch hook 30 is provided on the cover 10, and the latch hook structure is provided on the pot 20. It should be noted that, the main components of the latch hook structure (the ejector 60 and the locking member 40) are all elongated structures, so the latch hook structure is also an elongated structure as a whole, and the "extending direction of the latch hook structure" refers to the extending direction of the elongated structure formed by the latch hook structure, specifically, in this embodiment, the "extending direction of the latch hook structure" is the vertical direction in fig. 3.

Referring to fig. 5, the following description will be given of the moment arm on the ejector 60 and the lock 40 and the relationship therebetween, with the embodiment that "the distance between the second pivot portion 62 and the third abutment portion 64 is greater than the distance between the first pivot portion 42 and the second abutment portion 45, and the distance between the ejector 63 and the third abutment portion 64 is equal to the distance between the first abutment portion 44 and the second abutment portion 45", specifically, the force exerted by the retainer 50 on the first abutment portion 44 is F1, the force and the interaction force between the second abutment portion 45 and the third abutment portion 64 is F2, the force required to be exerted by the user on the ejector 63 is F3, the distance between the second pivot portion 62 and the third abutment portion 64 is (li+l2+l3), the distance between the first pivot portion 42 and the second abutment portion 45 is (l2+l3), the distance between the ejector 63 and the third abutment portion 64, and the distance between the first abutment portion 44 and the second abutment portion 45 are both L3, and the principle of leverage and the force are satisfied according to the L3: f1×l2=f2× (l2+l3), f2× (l1+l2+l3) =f3× (l1+l2), according to the two formulas above, it can be derived that: f3 =f1× (l1×l2+l2×l2+l2×l3)/(l1×l2+l2×l2+l2×l3+l1×l3), since (l1×l2+l2+l2×l3)/(l1×l2+l2×l2+l2+l3+l1×l3) is smaller than 1, F3 is smaller than F1, that is, without changing the pressing position (the pressing position is flush with the position of the retainer 50 acting on the first abutment portion 44 in the vertical direction), the user can overcome the holding force of the retainer 50 with a smaller force.

According to the above calculation formula, when the distance between the pushing portion 63 and the third supporting portion 64 is smaller than the distance between the first supporting portion 44 and the second supporting portion 45, the force required by the user is smaller.

In this embodiment, the first abutment portion 44 and the second abutment portion 45 are the abutment portion surfaces on the first rod 41, and when the distance between the first abutment portion 44 and the second abutment portion 45 is calculated, the distance between the centers thereof in the vertical direction is taken as the distance therebetween; in performing the distance calculation between the first pivot portion 42 and the second abutting portion 45, the distance between the center of rotation of the first pivot portion 42 and the center of the second abutting portion 45 in the vertical direction is taken as the distance therebetween. Similarly, the distance between the center of rotation of the second pivot portion 62 and the center of the third abutting portion 64 in the vertical direction is taken as the distance therebetween; the distance between the center of the push top 63 and the center of the third abutment 64 in the vertical direction is taken as the distance therebetween.

As shown in fig. 5, in the present embodiment, the ratio between the distance l1+l2 from the rotation center of the second pivot portion 62 to the center of the push-up portion 63 and the distance l1+l2+l3 from the rotation center of the second pivot portion 62 to the center of the third abutment portion 64 satisfies: (L1+L2)/(L1+L2+L3) is 0.25.ltoreq.0.4, preferably the ratio between the two may be 0.25, 0.31 or 0.4; the ratio between the distance L2 from the rotation center of the first pivot portion 42 to the center of the first abutment portion 44 and the distance l2+l3 from the rotation center of the first pivot portion 42 to the center of the second abutment portion 45 satisfies: 0.2.ltoreq.L2/(L2+L3). Ltoreq.0.3, preferably the ratio between the two may be 0.2, 0.24 or 0.3. Specifically, in the present embodiment, the distance l1+l2 from the rotation center of the second pivot portion 62 to the center of the push-top portion 63 is 28mm, the distance l1+l2+l3 from the rotation center of the second pivot portion 62 to the center of the third push-top portion 64 is 90mm, the distance L2 from the rotation center of the first pivot portion 42 to the center of the first push-top portion 44 is 20mm, the distance l2+l3 from the rotation center of the first pivot portion 42 to the center of the second push-top portion 45 is 82mm, and the distance from the rotation center of the first pivot portion 42 to the end of the first lock hook 43 is 23mm.
