[0011] Preferably, a sliding hole is provided on the side wall of the placement plate, an insertion rod is slidably connected inside the sliding hole, and a limiting hole is provided on the side wall of the clamping block for the insertion rod to be inserted and fixed.

[0012] The effect achieved by the above components is that the insertion rod is slidably inserted into the limiting hole to fix the block in another direction, and then cooperates with the fixation of the insertion column direction to lock the block.

[0013] Preferably, a spring is fixedly connected between the insertion rod and the sliding hole, a sliding groove connected to the sliding hole is opened on the side wall of the placement plate, a pull rod is fixedly connected to the surface of the insertion rod, and the pull rod extends from the sliding groove to the sliding hole.

[0014] The effect achieved by the above components is: when disassembly is required, the pull rod is pulled, and the pull rod drives the plug rod to squeeze the spring to slide out of the block, so that one side of the block is not constrained, and the plug column on the surface of the block is pulled out of the socket, so that the block can be quickly removed.

[0015] Preferably, the second wheel is a universal wheel.

[0016] The effect achieved by the above components is that the second wheel plays a role in steering the whole.

[0017] Preferably, a driving device is arranged between the first wheels, and the driving device includes a connecting shaft connecting the two first wheels, and also includes a motor installed at the bottom end of the bottommost placement plate, and the output end of the motor drives the pulley fixed on the surface of the connecting shaft to rotate through a belt drive, and drives the two first wheels to rotate through the connecting shaft.

[0018] Preferably, a handle is installed on the surface of the bracket, and the handle is a rotating speed regulator, and the speed of the motor is adjusted by the handle.

[0019] The effect achieved by the above components is: the handle can be a conventional speed regulator (such as the speed regulator on the handle of an electric vehicle to adjust the motor speed. Since the above functions and structures are fixed by existing conventional technical means, no further details will be given here), and a battery can be installed at the bottom of the placement plate to power the motor.
