[0018] In this embodiment: the upper clamping plate 11 and the lower clamping plate 12 are clamped on both sides of the joint of the two waterproof steel structure plates, the threaded tube 121 penetrates the corresponding waterproof steel structure plate to reach the position of the upper clamping plate 11, the upper clamping plate 11 is connected to the lower clamping plate 12 through the screw 2, and the hexagonal plate 21 limits the upper clamping plate 11, so that the upper clamping plate 11 and the lower clamping plate 12 can be fastened and fixed to the connection of the waterproof steel structure plate, and the hexagonal plate 21 is driven to rotate by a wrench or other tools, and the hexagonal plate 21 drives the screw 2 to rotate, so that the upper clamping plate 11 and the lower clamping plate 12 can stably connect and lock, and the threaded tube 121 increases the connection range between the lower clamping plate 12 and the screw rod 2, thereby further increasing the stability of the connection between the upper clamping plate 11 and the lower clamping plate 12, the upper clamping plate 11 supports the cover plate 3, and a torsion spring is arranged at the hinge position between the cover plate 3 and the upper clamping plate 11, the torsion spring drives the cover plate 3 to flip toward the upper clamping plate 11, and the other end of the cover plate 3 can be locked with the upper clamping plate 11 by means of an elastic lock, etc., the cover plate 3 supports a plurality of rotating carriers 31, and the rotating carriers 31 support a corresponding plurality of limit rods 32. The hexagonal plate 21 makes way for the several L-shaped limit plates 23 through the several side grooves 211. The L-shaped limit plates 23 are divided into long sections and short sections at the rotation axis point. When the L-shaped limit plates 23 are not in use, the long sections of the L-shaped limit plates 23 are inside the side grooves 211, so that the L-shaped limit plates 23 will not affect the driving effect of the external tools on the hexagonal plate 21. When the hexagonal plate 21 drives the screw rod 2 to rotate and tighten, the several L-shaped limit plates 23 are controlled to rotate, and the long sections of the L-shaped limit plates 23 extend out of the side grooves 211, and then the cover plate 3 drives the several rotating carriers 3. The upper clamping plate 11 is flipped, and the rotating carrier 31 drives the corresponding plurality of limit rods 32 to flip toward the L-shaped limit plate 23. The L-shaped limit plate 23 is clamped between the two limit rods 32, so that the rotating carrier 31 can limit the L-shaped limit plate 23 through the limit rods 32, thereby preventing the hexagonal plate 21 from driving the L-shaped limit plate 23 to rotate, thereby preventing the hexagonal plate 21 from loosening during use, and further preventing the connection between the two steel structure plates from loosening, thereby reducing the potential safety hazards to people and things near the steel structure.
[0019] The upper and lower clamping plates 11 and 12 are each designed with an anti-skid pad 13 at one opposite end, and the anti-skid pad 13 is in contact with the side wall of the threaded tube 121; the upper and lower clamping plates 11 and 12 are both in contact with the steel structure plate through the corresponding anti-skid pads 13, which reduces the friction loss problem caused when the upper and lower clamping plates 11 and 12 directly contact the plate, and improves the anti-skid stability of the upper and lower clamping plates 11 and 12 when limiting the plate.
[0020] A clearance groove 212 is provided at the top of the hexagonal plate 21, and one end of several L-shaped limit plates 23 are all located inside the clearance groove 212. A driving plug 33 is fixedly connected to the bottom end of the rotating carrier 31, and the driving plug 33 is inserted into the corresponding inner wall of the clearance groove 212, and the limiting plug rod 32 contacts the corresponding several L-shaped limit plates 23; the rotating carrier 31 supports the corresponding driving plugs 33, and the clearance groove 212 makes way for the driving plugs 33. When the rotating carrier 31 drives the several limiting plug rods 32 and the driving plug 33 to flip toward the direction of the hexagonal plate 21, the driving plug 33 is inserted into the corresponding clearance groove 212, and the driving plug 33 contacts and squeezes the short section of the L-shaped limit plate 23, so that the L-shaped limit plate 23 can rotate, so that the long section of the L-shaped limit plate 23 can extend out and connect with the limiting plug rod 32.
[0021] The top of the rotating carrier 31 is fixedly connected to the limit plate 311, and a plurality of limit grooves 34 are provided at the bottom end of the cover plate 3, and the limit plate 311 is rotatably connected to the inner wall of the limit groove 34; the cover plate 3 supports and limits the limit plate 311 through the limit groove 34 to prevent the limit plate 311 from driving the rotating carrier 31 to fall off, and the limit groove 34 controls the rotation range of the limit plate 311, so that the rotation range of the rotating carrier 31 is also controlled, so that when the limit rod 32 and the L-shaped limit plate 23 overlap, the rotating carrier 31 can be fine-tuned and rotated by controlling the rotating carrier 31, so that the L-shaped limit plate 23 can be stuck between the two limit rods 32 for limitation, and the limit groove 34 controls the rotation position of the rotating carrier 31 to control the rotation relaxation degree of the screw 2 within a reasonable range.
[0022] The limiting rod 32 does not contact the hexagonal plate 21, and the limiting plate 311 protrudes from the top of the cover plate 3; when the rotating carrier 31 drives the limiting rod 32 to flip in the direction of the L-shaped limiting plate 23, the limiting rod 32 will not be disturbed by the hexagonal plate 21, so that the limiting rod 32 can stably reach the periphery of the hexagonal plate 21 for limiting work, and one end of the limiting plate 311 is outside the cover plate 3, which makes it convenient for the staff to fine-tune the angle of the limiting rod 32.
[0023] The working principle and use process of the utility model are as follows: when the device is used, the upper clamping plate 11 and the lower clamping plate 12 are used to clamp the two waterproof steel structure plates, and then the hexagonal plate 21 is twisted to drive the screw 2 to rotate, and the screw 2 is connected to the threaded tube 121. The threaded tube 121 increases the connection range between the lower clamping plate 12 and the screw 2, thereby increasing the stability of the connection between the upper clamping plate 11 and the lower clamping plate 12. When the screw 2 is tightened, the cover plate 3 is controlled to flip, and the cover plate 3 drives a plurality of rotating carriers 31 to flip toward the direction of the hexagonal plate 21. The rotating carrier 31 drives a plurality of limit rods 32 and a driving plug 33 to flip toward the direction of the hexagonal plate 21, and the driving plug 33 is inserted In the corresponding yield groove 212, the driving plug 33 contacts and squeezes the short section of the L-shaped limit plate 23, so that the L-shaped limit plate 23 can rotate, and the long section of the L-shaped limit plate 23 can extend out to connect with the limit plug 32. The L-shaped limit plate 23 is clamped between the two limit plugs 32, so that the rotating carrier 31 can limit the L-shaped limit plate 23 through the limit plug 32, preventing the hexagonal plate 21 from driving the L-shaped limit plate 23 to rotate, thereby avoiding the hexagonal plate 21 from loosening during use, and further avoiding the loosening of the connection between the two steel structure plates, reducing the safety hazards to people and things near the steel structure.
