Meanwhile, an unlocking member for pressing the driving arm 422 is provided on the housing 1, and when the driving arm 422 is pressed by the unlocking member, the hooking portion 423 can be driven to disengage from the tooth groove 410.

The locking piece 42 is in a structural form of a locking hook 420 and can be hooked on the second side wall 412 on one side below the tooth groove 410, and the second side wall 412 can be in a form of inclining upwards from inside to outside so as to prevent the locking hook 420 from sliding and falling off; the form of hook, not only locking dependable performance, and the locking piece 42 of swing form do benefit to sparingly reduces the design size of self to make locking mechanism save space. Moreover, the locking hook 420 is designed into two parts, namely a hook part 423 and a driving arm 422, which are positioned on two sides of the pin 421, and the driving arm 422 undertakes operation and pressing, so that the hook part 423 is driven to be separated from the tooth socket 410, and the arrangement of the unlocking part and the second elastic part on the locking hook 420 is more convenient.

The second elastic member is preferably in the form of a torsion spring based on the arrangement of the locking hook 420 in the hinge-swing manner. Specifically, as shown in fig. 2, the upper housing 11 is fixedly provided with an installation shaft 426, the second torsion spring 425 is sleeved on the installation shaft 426, and two ends of the second torsion spring 425 respectively abut against the upper housing 11 and the driving arm 422; the driving arm 422 is provided with a connecting slot 424, one end of the second torsion spring 425 can be limited in the connecting slot 424, and the other end abuts against the housing 1. Thus, an elastic force into the tooth grooves 410 is preferably given to the locking hooks 420, which is advantageous for maintaining the reliability of the locking function of the locking hooks 420.

As shown in fig. 3, the unlocking member includes a pressing column 500 capable of moving up and down, and a spring 501 is provided between the pressing column 500 and the housing 1; the spring 501 serves to urge the pressed pressing post 500 to return. Preferably, the spring 501 is disposed at the bottom of the pressing column 500, and the bottom end of the spring 501 is pressed against the vehicle body or the housing 1. According to the design of the pressing column 500, the pressing operation is facilitated, the spring 501 is arranged at the bottom of the pressing column 500, the self-reset of the pressing column 500 is facilitated, and the locking hook 420 can be smoothly restored to the locking state.

The structure form and the arrangement position of the jacking mechanism can be flexibly designed. As shown in FIG. 2 in combination with FIG. 5, in the present embodiment, the inner case 2 has a tray 200 for holding a cup, a sidewall 201 for restricting the bottom of the cup; in order to improve the buffer effect of the bottom of the cup, a gasket 202 can be arranged in the inner shell 2; to improve the guiding effect of the up-and-down movement of the inner housing 2, a guide groove 100 may be formed on the housing 1, and the inner housing 2 may be guided and disposed in the guide groove 100.

Based on the above arrangement of the inner shell 2, the bottom of the inner shell 2 is provided with a bracket 203, the bracket 203 is rotatably provided with a rotating shaft 32, and the gear 31 is fixedly arranged on the rotating shaft 32; the first elastic element is a first torsion spring 33 sleeved on the rotating shaft 32.
