[0041] Further, the top end of the drawer body 2 is movably connected with a supporting top wheel 7, the inner cavity of the outer connecting rail 3 is movably connected with a supporting side wheel 8, the inner cavity of the shell 1 is movably connected with a supporting bottom wheel 9, the outer side of the shell 1 is fixedly installed with a mounting connecting plate 10, the outer connecting rail 3 and the inner connecting rail 4 are both provided with two groups, the outer connecting rail 3 is respectively installed on both sides of the drawer body 2, the inner connecting rail 4 is respectively installed on both sides of the inner cavity of the shell 1, the outer side of the supporting top wheel 7 is movably connected with the inner wall of the shell 1, the outer side of the supporting side wheel 8 is movably connected with the inner wall of the inner connecting rail 4, and the top of the supporting bottom wheel 9 is movably connected with the bottom of the outer connecting rail 3.
[0042] Working principle: in use, the device is installed to the designated position through the installation of the connecting plate 10, the connection of the shell 1 and the drawer body 2 is supported by the support top wheel 7, the support side wheel 8 and the support bottom wheel 9, and the friction between the shell 1 and the drawer body 2 can be reduced. In the process of moving the drawer body 2 to the outside of the shell 1, the limiting block 603 is moved, and in the movement process of the limiting block 603, it is clamped into the inner cavity of the limiting slot 604. When the drawer body 2 continues to be pulled, the arc surface of the limiting block 603 and the pulling force of the drawer body 2 on the limiting block 603 make the limiting block 603 move inward along the positioning sleeve rod 602, and the movement of the limiting block 603 drives the movement of the end of the linkage wire 503. When the limiting block 603 moves to the next limiting slot 604, the linkage wire 503 is moved by the rebound characteristics of the return spring 605, and the linkage wire 503 is moved by the movement of the linkage wire 503. The limiting block 603 is clamped into the inner cavity of the limiting slot 604, so as to limit the limiting block 603, and further limit the drawer body 2, so that the drawer body 2 will not slide when it is extended. When the drawer body 2 needs to be retracted into the inner cavity of the shell 1, the linkage wire 503 is moved by rotating the lock core connecting ring 502, and the limiting block 603 is moved inward by the movement of the linkage wire 503, so as to move out of the inner cavity of the limiting slot 604, so that the drawer body 2 can be moved. When the drawer body 2 is completely retracted into the inner cavity of the shell 1, the lock core connecting ring 502 is released, so that the lock core connecting ring 502 loses external force, and the linkage wire 503 is moved by the rebound characteristics of the return spring 605. The linkage wire 503 is moved to drive the rotation of the lock core connecting ring 502, and the linkage wire 503 is moved to drive the rotation of the lock core connecting ring 502. The linkage lock rod 504 is moved to extend, so that the outer end of the linkage lock rod 504 is clamped into the inner wall of the shell 1, and the drawer body 2 is locked and positioned.
[0043] In summary, through the cooperation of each component of the device, the problems of the existing equipment in actual use are solved. When the drawer body 2 is extended, the drawer body 2 cannot be positioned, when the equipment is inclined, the drawer body 2 is easily retracted automatically, it is not convenient for the user to take the articles in the inner cavity of the drawer body 2, and the automatic extension of the drawer body 2 easily causes the loss or damage of the articles. The device has the advantages of improving the safety and convenience of the equipment.
