Referring to Figures 1 to 6, a telescopic protective net with a slidable end portion includes a fixed protective fence 1, a movable protective fence 2 is slidably provided on one side of the fixed protective fence 1, a perforated mesh 4 is provided on the fixed protective fence 1 and the movable protective fence 2, a second kick plate 12 is fixedly installed on one side of the lower end of the fixed protective fence 1, a first kick plate 7 is fixedly installed on the same side of the lower end of the movable protective fence 2, a lower guide plate 9 is fixedly connected to the other side of the lower end of the movable protective fence 2, and the lower guide plate 9 and the second kick plate 12 are slidably connected.

Both the fixed guardrail 1 and the movable guardrail 2 include an outer frame and two support shafts 8. The two support shafts 8 are cross-arranged and fixedly connected to the outer frame at both ends. The perforated mesh 4 is installed on the surface of the support shafts 8 and the outer frame. The support shafts 8 cross-fixedly installed together are connected to the outer frame, thereby forming the structure of the fixed guardrail 1 and the movable guardrail 2. The perforated mesh 4 is then installed on the surface thereof for encapsulation and fixation to play a sealing role. A plurality of fixed shafts 6 are fixedly welded to the bottom of the fixed guardrail 1. A connecting plate 5 is welded to one side of each fixed shaft 6. A mounting hole is provided on the connecting plate 5. A plurality of fixed guardrails 1 and movable guardrails 2 can be assembled into a guardrail. The guardrail is fixed by the connecting plate 5 arranged at the lower end. Bolts pass through the mounting hole to mount the guardrail on the guide frame.

The upper end of the movable guardrail 2 is fixedly connected to the upper guide plate 3, the upper end of the fixed guardrail 1 is slidably connected to the upper guide plate 3, and a plurality of locking bolts 13 are threadedly installed on the surface of the upper guide plate 3, and the locking bolts 13 are threadedly inserted on the upper end surface of the fixed guardrail 1.

The first kick plate 7 and the second kick plate 12 are both provided with recesses 14 at the upper and lower ends, and a gap is formed between the lower guide plate 9 and the movable guardrail 2. The recess 14 at the lower end of the second kick plate 12 slides in the gap, and the second kick plate 12 and the lower guide plate 9 are connected in a mutually sliding and snap-fitting manner. When the fixed guardrail 1 slides relative to the movable guardrail 2, the stability of the trajectory can be ensured. The first kick plate 7 and the second kick plate 12 are respectively provided on the surfaces of the fixed guardrail 1 and the movable guardrail 2, and multiple fixed guardrails 1 and movable guardrails 2 can be assembled together for use.
