[0030] Further preferably, the extrusion claws are arranged obliquely, and the extrusion claws on the two clamping blocks form an eight-shaped structure.

At the same time, the first return spring is deformed under force, and the movement of the docking platform can synchronously drive the steel structure to move, so that the two sections of the steel structure can be docked.

[0035] It should be noted that, according to the usage, selecting eccentric cams of different sizes can change the distance that the roller is pushed to move, thereby improving the flexibility of use.

[0036] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device.
