Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example (b):

a pneumatic anti-falling component with high safety is shown in figure 1 and comprises a cross arm 1 and an arm support 2, wherein the cross arm 1 is mounted on the arm support 2 and reciprocates up and down along the arm support 2.

As shown in fig. 1, the cross arm 1 is provided with the anti-falling assembly 3, the anti-falling assembly 3 comprises a safety seat 4, a stop plate 5 and a cylinder 6, the safety seat 4 is welded on the cross arm 1, the stop plate 5 is slidably arranged on the safety seat 4 in a penetrating manner, the cylinder 6 is further connected onto the safety seat 4, a protective cover 7 is arranged on the cylinder 6, and the phenomenon that the cylinder 6 falls off can be reduced by the protective cover 7.
