A card slot 9 is provided at the top of the secondary connecting block 8, and the shape of the card block 6 matches the card slot 9. The rear end of the card block 6 and the front end of the secondary connecting block 8 are both arc surfaces. The lower side of the inner wall of the card block 6 is fixedly connected to a main spring 7, and the other end of the main spring 7 is fixedly connected to the top of the pull rod 4. The lower side of the outer wall of the pull rod 4 is fixedly connected with a tension spring 5, and the other end of the tension spring 5 is fixedly connected to the top of the main connecting block 3.

[0029] Specifically, when the protective frame bodies 1 need to be disassembled, it is only necessary to pull the pull rod 4, and the pull rod 4 drives the card block 6 to move upward, and the card block 6 is taken out of the card slot 9, and the secondary connecting block 8 can be taken out of the main connecting block 3 to complete the disassembly. When connecting, it is only necessary to insert the secondary connecting block 8 from the rear end of the main connecting block 3 and pull it forward to insert the card block 6 into the card slot 9 to complete the installation connection between the two protective frame bodies 1. The operation is simple, reduces construction time and labor costs, avoids delays in construction progress, and improves work efficiency.

[0030] Reference Figure 4 and Figure 5 As shown, the base 10, the top of the base 10 is fixedly connected to the bottom end of the connecting column 2, the inner wall of the connecting column 2 is rotatably connected to the knob 11, and a rotating rod 15 is provided at the rear end of the knob 11 for rotating the rotating rod 15, and a support column 19 is provided at the opposite end of the rotating rod 15 for lifting the support column 19, so as to limit the knob 11 after the adjustment is completed, and the outer walls of the support columns 19 are slidably connected to the front and rear sides of the inner wall of the base 10, and the main bevel gear 12 is fixedly connected to the rear end of the knob 11. The outer walls of the main bevel gear 12 are meshed with the sub-bevel gear 13, and the bottom end of the sub-bevel gear 13 is fixedly connected to the transmission rod 14, and the inner wall of the transmission rod 14 is fixedly connected to the outer wall of the rotating rod 15, and the bottom end of the transmission rod 14 is rotatably connected to the lower side of the inner wall of the base 10. The connecting seat 16 is rotatably connected to the outer wall of the rotating rod 15 on both sides, and the opposite end of the connecting seat 16 is slidably connected to the sliding plate 17. The lower side of the inner wall of the sliding plate 17 is rotatably connected to the connecting rod 18, and the other end of the connecting rod 18 is rotatably connected to the support column 19. The left and right ends of the sliding plate 17 are slidably connected to the left and right sides of the inner wall of the base 10, and are fixedly connected to the connecting frame 21 at the front end of the connecting column 2. The inner wall of the connecting frame 21 is slidably connected to the limit plate 23. The upper and lower sides of the outer wall of the knob 11 are provided with a limit groove 20, and the outer wall of the limit plate 23 is arranged on the inner wall of the lower side limit groove 20. The rear end of the limit plate 23 is fixedly connected to a secondary spring 22, and the other end of the secondary spring 22 is fixedly connected to the front side of the inner wall of the connecting frame 21. The bottom end of the base 10 is fixedly connected to a universal wheel.

[0031] Specifically, when movement is required, it is only necessary to press the limit plate 23 backward and rotate the knob 11 in the opposite direction. The knob 11 drives the sliding plates 17 on both sides to slide toward the middle and drives the support column 19 to rise upward, and the universal wheel is lowered to push the protective frame body 1. At the same time, after finishing rotating the knob 11, the limit plate 23 is released, and the limit plate 23 is clamped into the limit groove 20 by the elastic force of the secondary spring 22 to limit the knob 11, avoiding unnecessary movement and improving stability. By rotating the knob 11, the support column 19 can be slid downward and the protective frame body 1 can be propped up. At the same time, the knob 11 is rotated in the opposite direction to retract the support column 19. The movement of the protective frame body 1 is facilitated by the universal wheel at the bottom end of the base 10.

[0032] Working principle: First, the worker manually pushes the protective frame body 1 to the edge of the foundation pit, then pushes the limit plate 23 backward, removes the limit plate 23 from the limit slot 20, and then rotates the knob 11. The knob 11 drives the main bevel gear 12, and the main bevel gear 12 drives the secondary bevel gear 13 to rotate. The secondary bevel gear 13 drives the transmission rod 14, and the transmission rod 14 drives the rotating rod 15 on the inner wall to rotate. The rotation of the rotating rod 15 will also synchronously drive the connecting seat 16 to slide on the opposite end of the sliding plate 17, and will also drive the sliding plate 17 slides to both sides, and the sliding plate 17 slides to both sides, which will also drive the support column 19 to slide downward through the connecting rod 18, and prop up the protective frame body 1 upward. At the same time, when the protective frame body 1 needs to be installed with each other, it is only necessary to align the secondary connecting block 8 with the rear side of the main connecting block 3, and insert the secondary connecting block 8 into the inner wall of the main connecting block 3. After the arc surface of the secondary connecting block 8 and the arc surface of the card block 6 are released, the card block 6 slides upward. After the secondary connecting block 8 is installed in place, the card block 6 is clamped into the card slot 9 through the main spring 7, and the installation is completed.
