69 are arranged on the side wall of body of rod hollow cavity, and the button 65 is connect with elevator, and button is located in the hollow cavity of the body of rod, described
The bottom end of vertical inserted block cooperates in the vee gutter.
Hook-shaped groove 330 is opened up on the side wall of card slot 33, hook-shaped groove profiling is equipped with card slot bullet in the hook portion, the bottom of card slot
Property part 34.
The elastic telescopicing rod 60 and the card slot 33 constitute the position limiting structure of support arm 30.
In practical operation, initially, support arm 30 is trapped in support arm sunk structure 12, and pulley spindle 31 is trapped in pulley spindle recess
Structure 13, a pair of support pulley 32 are located at the left and right sides of cabinet 10.
When needing mobile box 10, any support pulley in user's foot-propelled or manually a pair of of support pulley 32 drives and slides
Wheel shaft 31 and support arm 30, support arm 30 are rotated around articulated shaft 11, the back of support arm 30 and pulley spindle 31 far from cabinet, and one
To the support left and right sides of the pulley 32 far from cabinet, with idler wheel 20 at the state of standing like the legs of a tripod, a pair of support pulley 32 and idler wheel 20
It lands, cabinet 10 leans forward, and the weight of cabinet is completely by a pair of support pulley and roller supporting.
When a pair of support pulley 32 and idler wheel 20 at stand like the legs of a tripod state when, the bottom of elastic telescopicing rod 60 and the card slot
33 faces.
User presses down on the body of rod 61, and the bottom end of the body of rod is downwardly into card slot 33, and hook portion 63 is squeezed by card slot side wall
Pressure, hook portion elastic component 64 are shunk, and gather elastic potential energy.The bottom end of the body of rod continues to act on card slot elastic component 34 along card slot downlink,
