DETAILED DESCRIPTION

[0019] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, so that the embodiments of the application described here, based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

A hose 15 is connected to one side of the second airbag 14, and the hose 15 is connected to the first airbag 8. When in use, the slider 4 is squeezed, causing the piston rod 7 to move downward along the fixed tube 6, and then the gas enters the second airbag 14 through the first connecting tube 13, so that the bulged second airbag 14 cushions the slider 4. At the same time, part of the gas in the second airbag 14 enters the first airbag 8 through the hose 15, causing the first airbag 8 to inflate and swell, and then the slider 4 continues to move downward. At this time, the second airbag 14 cannot continue to deform, so that the slider 4 drives the overall structure connected to the slide plate 17 to move downward through the piston rod 7 and the fixed tube 6, and the spring 11 contracts. At the same time, when the slide plate 17 moves, the pressure block 16 moves downward and squeezes the first airbag 8, so that the slider 4 is further shock-absorbing and buffered.

[0021] In the present utility model, it should be noted that a telescopic rod 12 is fixed to the inside of the slide groove 5 by bolts, and the spring 11 is sleeved on the outside of the telescopic rod 12, the slide plate 17 moves up and down along the slide groove 5, the telescopic rod 12 is extended and retracted, and the bottom of the slider 4 can contact the second airbag 14, and the telescopic rod 12 can guide the slide plate 17 so that it can move stably. Mounting holes 1 are opened on multiple sides of the base plate 2, and the mounting holes 1 are symmetrically distributed, which is convenient for the staff to install the base plate 2. Fixed ribs 9 are fixed to both sides of the fixed plate 10 by bolts, and the fixed ribs 9 are fixed to the base plate 2. The fixed ribs 9 make the connection between the fixed plate 10 and the base plate 2 more firmly.

[0022] Working principle: When in use, the slider 4 is squeezed, causing the piston rod 7 to move downward along the fixed tube 6, and then the gas enters the second airbag 14 through the first connecting tube 13, so that the bulged second airbag 14 cushions the slider 4. At the same time, part of the gas in the second airbag 14 enters the first airbag 8 through the hose 15, causing the first airbag 8 to inflate and swell. Then the slider 4 continues to move downward. At this time, the second airbag 14 cannot continue to deform, so that the slider 4 drives the overall structure connected to the slide plate 17 to move downward through the piston rod 7 and the fixed tube 6, and the spring 11 contracts. At the same time, when the slide plate 17 moves, the pressure block 16 moves downward and squeezes the first airbag 8, so that the slider 4 is further shock-absorbing and buffered.
