Specifically, one end of the first telescopic rod 2 is welded to the central fixed plate 1, and the other end of the first telescopic rod 2 is hinged to two connecting components 3, and the connecting component 3 is connected to the first fixed plate 4; specifically, two fixed shafts are arranged on the first telescopic rod 2, and a circular hole is arranged on the connecting component 3, and the connecting component 3 is hinged to the first telescopic rod 2 through the circular hole and the fixed shaft.

[0026] The connecting assembly 3 is used to connect the first telescopic rod 2 and the first fixed plate 4; the connecting assembly 3 includes a first connecting rod 301, a spring 302 and a second connecting rod 303, the first telescopic rod 2 is connected to one end of the spring 302 through the first connecting rod 301, and the other end of the spring 302 is connected to the first fixed plate 4 through the second connecting rod 303; specifically, a circular hole is set at one end of the first connecting rod 301, and the first telescopic rod 2 is connected through the circular hole and the central axis, the first connecting rod 301 and the second connecting rod 303 are both connected to the spring 302 by welding, and threaded holes are set on the second connecting rod 303 and the first fixed plate 4, so as to realize the connection between the second connecting rod 303 and the first fixed plate 4 through bolts and threaded holes. In the embodiment of the present application, when the first telescopic rod 2 reaches the maximum length but the first fixed plate 4 still cannot reach the top of the cargo, the spring 302 and another second connecting rod 303 can be continuously connected to the second connecting rod 303 until the first fixed plate 4 on the second connecting rod 303 reaches the top of the cargo.

[0027] The first fixed plate 4 is used to fix the top of the cargo. The first fixed plate 4 includes a sub-fixed plate 401 and a movable plate 402, and the sub-fixed plate 401 is hinged to the movable plate 402; specifically, a threaded hole is set at one end of the sub-fixed plate 401, and is connected by a bolt and a second connecting rod 303; a hinge shaft is set at the other end of the sub-fixed plate 401, and the movable plate 402 is hinged by the hinge shaft, and the movable plate 402 can be bent toward the direction of the central fixed plate 1. In the embodiment of the present application, the sub-fixed plate 401 and the movable plate 402 are both right-angle plates. By setting the right-angle plates, the edges of the cargo can be more accurately clamped, achieving a better fixing effect.

[0028] The bottom of the sub-fixed plate 401 is connected to the bottom fixing assembly 6 through the second telescopic rod 8, and the bottom fixing assembly 6 is used to fix the cargo and the bottom of the car body; the bottom fixing assembly 6 includes a first support plate 601 and a second support plate 602, the sub-fixed plate 401 is connected to the first support plate 601 through the second telescopic rod 8, and the first support plate 601 is hinged to the second support plate 602; specifically, the second telescopic rod 8 is welded to the bottom of the sub-fixed plate 401 and the top of the first support plate 601, and the bottom of the first support plate 601 is connected to the second support plate 602 through a hinge axis. In the embodiment of the present application, the second support plate 602 can be bent toward the direction where the cargo is located, or toward the direction where the cargo is not located, and the maximum bending degree is 90°; when the volume of the cargo in the carriage is too large, the second support plate 602 can be bent toward the direction where the cargo is located, and the second support plate 602 and the bottom of the carriage are connected through the threaded holes and bolts on the second support plate 602; when there is still a large remaining space after placing the cargo in the carriage, the second support plate 602 can be bent toward the direction where the cargo is not located, and the second support plate 602 and the bottom of the carriage are connected.

[0029] A second fixing plate 5 is arranged on the central fixing plate 1. The second fixing plate 5 is a right-angle telescopic plate, so that the second fixing plate 5 is connected to the central fixing plate 1 through bolts and threaded holes, so as to better clamp the edge of the goods.
