Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-5, the present embodiment includes a box body 1 and a box cover 2, wherein the box cover 2 is disposed at the upper end of the box body 1 and is hinged to the box body 1; four angle departments of the bottom of box 1 are equipped with landing leg 3, and landing leg 3 is articulated with box 1, and open the bottom of box 1 has the first accepting groove 11 with landing leg 3 matched with, and landing leg 3 includes telescopic component 31 and altitude mixture control pole 32, and telescopic component 31's one end is articulated with box 1, the other end and altitude mixture control pole 32 threaded connection. The first receiving groove 11 is convenient for receiving the supporting leg 3 in the box body 1, so that the tool box has a simple structure and is convenient to carry.

Two landing legs 3 of the one end of box 1 are the splayed and distribute, and this design does benefit to the stationarity that improves the toolbox.

The telescopic assembly 31 includes: the height adjusting device comprises a first expansion plate 311, a second expansion plate 312 and a limiting piece 313, wherein the first expansion plate 311 is sleeved on the second expansion plate 312 and is in sliding connection with the second expansion plate 312, the limiting piece 313 is arranged on the second expansion plate 312 and is used for limiting the second expansion plate 312 to move, the first expansion plate 311 is hinged to the box body 1, and one end, far away from the first expansion plate 311, of the second expansion plate 312 is in threaded connection with the height adjusting rod 32.

The limiting member 313 comprises a limiting plate 3131 and a spring 3132, the second retractable plate 312 is provided with a second accommodating groove 3121, the limiting plate 3131 and the spring 3132 are both accommodated in the second accommodating groove 3121, one end of the limiting plate 3131 away from the first retractable plate 311 is hinged to the second retractable plate 312, and the other end is provided with the spring 3132; the spring 3132 is disposed between the limiting plate 3131 and the second expansion plate 312. The upper end of the stop plate 3131 is ejected out of the second receiving groove 3121 by the spring 3132, and the stop plate 3131 abuts against the first retractable plate 311 to limit the sliding of the second retractable plate 312. At this time, the end surface of the upper end of the position-limiting plate 3131 is parallel to the first retractable plate 311, and this arrangement enables the position-limiting plate 3131 to stably abut against the first retractable plate 311, preventing the position plate 3131 from moving. When the tool box needs to be retracted and taken away, the second retractable plate 312 slides into the first retractable plate 311 by pressing the limiting plate 3131 back into the second receiving groove 3121.
