The top end of the platform main body 3-1 is provided with a steel cable connecting position 3-3, and the steel cable connecting position 3-3 is used for being connected with a steel cable 2-7. The back of the platform main body 3-1 is provided with guide wheels 3-4, and the guide wheels 3-4 walk up and down along two guide rails 7.

As shown in FIG. 4, the self-locking mechanism 2-6 includes a pull rod 4-1, a spring 4-2, a pawl 4-3, a ratchet 4-4, and a protective cover 4-5. The pull rod 4-1 is directly hinged with the pawl 4-3; the middle of the pawl 4-3 is arranged on the protective cover 4-5 through a pin shaft and can rotate relative to the pin shaft; the spring 4-2 is placed between the pawl 4-3 and the protective cover 4-5 in a pressed manner and can press one end of the pawl 4-3 on the ratchet wheel 4-4; the ratchet wheel 4-4 is connected with the extending shaft of the winding drum 2-8 through a key.
