The elastic element 12 may be in contact with the blocking element 11, directly connected or indirectly connected, for example by means of a connecting element. The primary purpose of the design relationship between the elastic member 12 and the blocking member 11 is to transmit the force acting on the blocking member 11 to the elastic member 12, so that the elastic member 12 is elastically deformed, and when the external force is removed, the elastic member 12 drives the blocking member 11 to return to the free state.

Referring to fig. 3, a step is provided between the second end 111 and the first end 112 of the blocking member 11, and the sectional area of the first end 112 is smaller than that of the second end 111. One end 121 of the spring is sleeved on the first end 112, and the other first end is a free end 122. Of course, one end 121 of the spring may be fixedly connected to the first end 112.

The trigger 13 includes a body 131 and a head 132, the diameter of the head 132 is larger than that of the body 131, and the outer wall of the body 131 is provided with external threads. The main function of the trigger 13 is to receive an external force, thereby driving the blocking member 11 to move. In this embodiment, the trigger 13 is detachably connected to the blocking member 11. Such a detachable connection, which facilitates assembly, also contributes to a reduction in production costs, and in the event of damage or loss of the triggering element 13 or the blocking element 11, can be used again without the need to replace the entire crash protection device 1. In other embodiments, the trigger 13 can be eliminated, and the external force directly acts on the blocking member 11, so that the blocking member 11 compresses the elastic member 12 to retract the second end 111 of the blocking member 11 into the body 2.
