[0023] In this embodiment, both sides of the top of the T-shaped plate 5 slide through the sliding rod 8, and both sides of the T-shaped plate 5 are provided with round holes that are compatible with the sliding rod 8. The bottoms of the two sliding rods 8 are fixedly connected to the same limit plate 10, and the tops of the two sliding rods 8 are fixedly connected to the same U-shaped frame 6. A plurality of rollers 7 are rotatably connected at equal distances between the two sides of the top of the U-shaped frame 6.

[0024] In this embodiment, the circumferential surfaces of the two slide bars 8 between the U-shaped frame 6 and the T-shaped plate 5 are sleeved with first springs 9. The first springs 9 are arranged so that the U-shaped frame 6 can be quickly reset when the protective plate is not on the U-shaped frame 6.

[0025] In this embodiment, a strip hole 501 is provided at the bottom of the T-shaped plate 5 near the rotating rod 20, and an L-shaped plate 14 is slidably connected in the strip hole 501, and the L-shaped plate 14 is adapted to the right-angled trapezoidal block 19, and a same limiting rod 12 is fixedly connected between the two ends of the strip hole 501, and the limiting rod 12 slides through the L-shaped plate 14, and a circular hole adapted to the limiting rod 12 is provided on the L-shaped plate 14, and a second spring 13 is sleeved on the side of the limiting rod 12 away from the rotating disk 16, and a pull rod 15 is also fixedly connected to the side of the outer side of the L-shaped plate 14 away from the rotating disk 16. The setting of the right-angled trapezoidal block 19 prevents the U-shaped frame 6 from rotating smoothly when it descends, and is not affected when it rotates in the opposite direction.

[0026] In this embodiment, a rack 11 is fixedly connected to the bottom of the U-shaped frame 6 near the rotating rod 20, and the bottom of the rack 11 passes through the T-shaped plate 5 and meshes with the gear 21. A square hole matching the rack 11 is opened at the bottom of the T-shaped plate 5. Through the arrangement of the rack 11 and the gear 21, when the U-shaped frame 6 descends, the turntable 16 is driven to rotate.

[0027] In this embodiment, a U-shaped plate 3 is fixedly connected to the side of the connecting plate 1 away from the T-shaped plate 5, and two second fixing holes 4 are provided on the U-shaped plate 3. First fixing holes 2 are provided on both sides of the top of the connecting plate 1. The second fixing holes 4 are provided to fix the connecting plate 1 to the column.

[0028] Working principle: A connecting piece for installing a guardrail. Now fix the column on the ground, and then fix the connecting plate 1 on the column through the second fixing hole 4. In the natural state, due to the setting of the first spring 9, the U-frame 6 and the roller 7 are located at the highest point. When in use, the guardrail plate is lifted to the multiple rollers 7 on the top of the U-frame 6. At this time, the user can place the guardrail plate on the roller 7 without too much force, and then gradually adjust the guardrail plate so that the guardrail plate drops to a suitable position, and pull the pull rod 15 so that the pull rod 15 brings the L-shaped plate 14 to compress the second spring 13. At this time, the L-shaped plate 14 is separated from the right-angled trapezoidal block 19. Under the action of the second spring 13, the L-shaped plate 14 is also quickly reset. Since the guardrail plate is placed on the U-frame 6, the U-frame 6 receives a large gravity. When the L-shaped plate 14 is When the right-angled trapezoidal block 19 is separated, the U-shaped frame 6 descends, and the gear 21 is set to rotate with the turntable 16. When the turntable 16 rotates one circle, the right-angled trapezoidal block 19 is again clamped by the L-shaped plate 14, so that the U-shaped frame 6 will not continue to descend, thereby achieving that every time the pull rod 15 is turned once, the turntable 16 rotates one circle, and the U-shaped frame 6 descends a little with the guardrail plate until the fixing hole of the guardrail plate is at the same horizontal position as the first fixing hole 2 on the connecting plate 1, and the guardrail plate is slid. Under the action of the roller 7, the fixing hole of the guardrail plate can be aligned with the first fixing hole 2, so that the user can quickly fix it. When the user lifts the guardrail plate, under the action of the slide bar 8, the U-shaped frame 6 is reset. At the same time, under the action of the right-angled trapezoidal block 19, the reversal of the turntable 16 is not hindered by the L-shaped plate 14.
