A clamping ring 215 is clamped and connected to the outer wall of the clamping column 212, a cross beam 216 is fixedly connected to the outer wall of the clamping ring 215, a strengthening plate 217 is fixedly connected to one end of the cross beam 216 away from the clamping ring 215, a sliding groove 218 is opened at the top end of the inner wall of the car 1, a sliding block 219 is slidably connected to the inner wall of the sliding groove 218, and the bottom end of the sliding block 219 is fixedly connected to the top end of the strengthening plate 217.

[0034] Further, the number of the cross beams 216 is four, and two cross beams 216 are in a group and are symmetrically distributed on the outer wall of the strengthening plate 217 in a left - right symmetrical structure. In this way, the strengthening plate 217 can be supported, and thus, through the mutual cooperation between the strengthening plate 217 and the cross beam 216, the top end of the car 1 is initially strengthened.

Then, pull the pull plates 213 at the four corners, and drive the clamping columns 212 to move downward. At the same time, the pull plates 213 compress the springs 214. At this time, the slider 219 can drive the reinforcing plate 217 to move to the center position of the top of the car 1. At the same time, the snap ring 215 will move to the position directly above the clamping column 212. Then release the pull plates 213, and the springs 214 will rebound and reset, driving the clamping columns 212 to insert into the inner wall of the snap ring 215, completing the installation of the cross beam 216 and the reinforcing plate 217. At the same time, through the cooperation between the cross beam 216 and the reinforcing plate 217, the top position of the car 1 can be initially strengthened and supported.

[0041] Through the cooperation between the longitudinal beam 222 and the second fixing plate 223, it can further support and strengthen on the basis of the initial support and strengthening completed by the cross beam 216 and the first fixing plate 211. At the same time, through the snap connection between the card slot 224 and the longitudinal beam 222, it can ensure that the intersection of the cross beam 216 and the longitudinal beam 222 is mutually embedded, thereby improving the strength of the intersection of the cross beam 216 and the longitudinal beam 222.

[0042] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
