The knob plunger 3023 comprises a plunger body, a plunger pin and a spring. The plunger body is sleeve-shaped, the first end of the plunger body is provided with two limiting grooves uniformly distributed in the circumferential direction, and the second end of the plunger body is an opening for the locking end of the plunger pin to protrude out. One end of the plunger pin is a handle, the other end of the plunger pin penetrates into the first end of the plunger body and penetrates out of the second end of the plunger body, and the spring is arranged between the plunger pin and the plunger body. The spring is used to keep the plunger pin in the tendency of moving from the first end to the second end of the plunger body. Two limiting protrusions uniformly distributed in the circumferential direction are arranged on the plunger pin. When the limiting protrusions on the plunger pin cooperate with the limiting grooves, the locking end of the plunger pin protrudes out of the second end of the plunger body, and the stop limiting mechanism is in the first state. When the limiting protrusions on the plunger pin are separated from the limiting grooves and the plunger pin is rotated relative to the plunger body to the outside of the limiting grooves, the plunger pin cannot move relative to the plunger body in the axial direction, and the locking end of the plunger pin is retracted into the second end of the plunger body, and the stop limiting mechanism is in the second state.

[0044] As shown in the embodiment of the present application, the stop limiting mechanism comprises a knob plunger 3023 and a stop limiting hole arranged on the guardrail body 3022.

The plunger body is sleeve-shaped, the first end of the plunger body is provided with two limiting grooves uniformly distributed in the circumferential direction, and the second end of the plunger body is an opening for the locking end of the plunger pin to protrude out. One end of the plunger pin is a handle, the other end of the plunger pin penetrates into the first end of the plunger body and penetrates out of the second end of the plunger body, and the spring is arranged between the plunger pin and the plunger body. The spring is used to keep the plunger pin in the tendency of moving from the first end to the second end of the plunger body. Two limiting protrusions uniformly distributed in the circumferential direction are arranged on the plunger pin. When the limiting protrusions on the plunger pin cooperate with the limiting grooves, the locking end of the plunger pin protrudes out of the second end of the plunger body, and the stop limiting mechanism is in the first state. When the limiting protrusions on the plunger pin are separated from the limiting grooves and the plunger pin is rotated relative to the plunger body to the outside of the limiting grooves, the plunger pin cannot move relative to the plunger body in the axial direction, and the locking end of the plunger pin is retracted into the second end of the plunger body, and the stop limiting mechanism is in the second state.
