Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Example 1: referring to fig. 1-5, the retractable shock pad includes a hollow cylindrical main body 41, an upper end of the main body 41 is an inverted cone, ribs 42 spaced apart along a circumferential direction are disposed on an inner circumferential surface of the main body 41, an upper end of each rib 42 is flush with an upper end of the main body 41, a lower end of each rib 42 extends out of a bottom of the main body 41 to form an elastic contact portion, two annular grooves, namely a first annular groove 43 and a second annular groove 45, are axially spaced apart on an outer circumferential surface of the main body 41, and grooves 44 recessed along the main body towards the ribs 42 are circumferentially spaced apart on the outer circumferential surface of the main body 41.

Further, the recess depth of the second annular groove 45 is larger than the recess depth of the first annular groove 43.

Further, the ribs 42 have a trapezoidal structure.

Further, the length L1 of the lower end of the rib 42 extending out of the bottom of the main body 41 is 1.0-1.5 mm.

Further, the length L1 of the lower end of the rib 42 protruding out of the bottom of the main body 41 is 1.2 mm.
