Through holes 211 are respectively opened at both ends of the L-shaped rod 1, and bolts 212 are slidably inserted into the inner wall of the through hole 211. A plurality of threaded holes 213 are opened on the outer surface of the plate body 4, and the outer surface of the bolt 212 is threadedly connected with the inner wall of the threaded hole 213. By setting the pressing block 24, when the concrete formwork is clamped and fixed, the two pressing blocks 24 on the outer surface of the L-shaped rod 1 are respectively attached to the inner wall of the threaded hole 213. The L-shaped rod 1 is put on the outside of the two mutually perpendicular plates 4, and the L-shaped rod 1 is pushed to move in the direction of the plate 4. When the L-shaped rod 1 moves, the two round rods 23 will slide on the inner wall of the U-shaped block 22 and compress the spring 25, and the L-shaped rod 1 is moved until the two ends of the L-shaped rod 1 are respectively attached to the outside of the two mutually perpendicular plates 4, and then the two threaded rings 26 are respectively rotated on the outer surfaces of the two round rods 23, so that the two threaded rings 26 move in the same direction on the outer surface of the round rod 23, and one side is pressed against the outer surface of the U-shaped block 22 and the inner wall of the rectangular groove 21, respectively, to the round rod 23. The rod 23 and the pressure block 24 are fixed at the position of the outer surface of the L-shaped rod 1, and then the bolt 212 is used to pass through the through hole 211 on the outer surface of the L-shaped rod 1 and inserted into the threaded hole 213 on the outer surface of the plate body 4.

A plurality of protrusions 28 are fixedly connected to the outer surface of the threaded ring 26, and the protrusions 28 are distributed in a circle on the outer surface of the threaded ring 26. By pressing the protrusions 28 on the outer surface of the threaded ring 26 with your hand, you can more conveniently push the threaded ring 26 to rotate without slipping your hand.
[0031] Reference Figures 2-4As shown in the figure, in this embodiment: One end of the round rod 23 away from the pressing block 24 is fixedly connected with a stop block 29. The length of the stop block 29 is greater than the diameter of the round rod 23. By setting the stop block 29, the moving range of the threaded ring 26 on the outer surface of the round rod 23 can be restricted, and it is possible to avoid the threaded ring 26 on the side close to the stop block 29 from falling off the surface of the round rod 23 and being lost when it rotates outward. On both sides of the inner wall of the U-shaped block 22, positioning pieces 210 are respectively fixedly connected. The two positioning pieces 210 are respectively located on the left and right sides of the spring 25. By setting the positioning pieces 210, the external shape of the spring 25 can be strengthened, and it is possible to avoid the spring 25 from being inclined due to the force on both sides when it is compressed, affecting the normal use of the spring 25. Elastic ropes 214 are respectively fixedly connected to both ends of the L-shaped rod 1. One end of the two elastic ropes 214 away from the L-shaped rod 1 is fixedly connected to one end of the bolt 212. By setting the elastic ropes 214, the bolt 212 can be always fixed on the outside of the L-shaped rod 1, which is convenient for taking the bolt 212 when using the fixture and avoiding the bolt 212 from falling off and being lost.
[0032] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown in the figure, in this embodiment: A strengthening device 3 is provided on one side of the L-shaped rod 1. The strengthening device 3 includes a groove rod 32. A sliding rod 33 is slidably connected to the inner wall of the groove rod 32. A clamping block 34 is respectively fixedly connected to the top end of the groove rod 32 and the bottom end of the sliding rod 33. A threaded cylinder 35 is rotatably connected to one side of the groove rod 32. A screw rod 36 is fixedly connected to one side of the sliding rod 33. The outer surface of the screw rod 36 is threadedly connected to the inner wall of the threaded cylinder 35. A clamping groove 31 is provided on one side of the L-shaped rod 1. After the L-shaped rod 1 and the fastening device 2 are installed on the outside of the plate body 4, the threaded cylinder 35 can be rotated according to the distance between the upper and lower two L-shaped rods 1 on one side of the plate body 4, so that the threaded cylinder 35 moves up and down on the outer surface of the screw rod 36, driving the groove rod 32 to slide on the outer surface of the sliding rod 33, adjusting the overall length of the sliding rod 33 and the groove rod 32 and fixing them. Then, the clamping block 34 at one end of the groove rod 32 and the clamping block 34 at one end of the sliding rod 33 are respectively inserted into the clamping grooves 31 on one side of the upper and lower two L-shaped rods 1 to support between the upper and lower two L-shaped rods 1, improving the stability when using the fixture. A plurality of convex strips 37 are fixedly connected to the outer surface of the clamping block 34. The convex strips 37 are rubber strips made of rubber. By setting the rubber convex strips 37, the friction force between the clamping block 34 inserted into the clamping groove 31 and the inner wall of the clamping groove 31 can be increased, so that the clamping block 34 is not easily accidentally separated from the inside of the clamping groove 31.
[0033] Working principle: When using a fixture to clamp and fix a concrete formwork, place the four plate bodies 4 perpendicular to each other on the outside of the steel reinforcement cage. Then, on the outside of the plate bodies 4, press one side of the two pressing blocks 24 on the outer surface of the L-shaped rod 1 against the outside of the two perpendicular plate bodies 4 respectively. Push the L-shaped rod 1 towards the plate bodies 4. When the L-shaped rod 1 moves, the two round rods 23 will slide on the inner wall of the U-shaped block 22 and compress the spring 25. Move the L-shaped rod 1 until both ends of the L-shaped rod 1 are in contact with the outside of the two perpendicular plate bodies 4 respectively. Then, rotate the two threaded rings 26 on the outer surfaces of the two round rods 23 respectively, so that the two threaded rings 26 move in the same direction on the outer surfaces of the round rods 23 and press one side against the outer surface of the U-shaped block 22 and the inner wall side of the rectangular groove 21 respectively, to fix the positions of the round rods 23 and the pressing blocks 24 on the outer surface of the L-shaped rod 1. Subsequently, use the bolt 212 to pass through the through hole 211 on the outer surface of the L-shaped rod 1 and insert it at the threaded hole 213 on the outer surface of the plate body 4. Rotate the bolt 212 to make the bolt 212 threadedly connected to the inner wall of the threaded hole 213, and fix the L-shaped rod 1 on the outside of the plate body 4. Use several L-shaped rods 1 and fastening devices 2 to reinforce the four corners of the plate body 4. After the L-shaped rods 1 and the fastening devices 2 are installed, the threaded cylinder 35 can be rotated according to the distance between the upper and lower L-shaped rods 1 on one side of the plate body 4, so that the threaded cylinder 35 moves up and down on the outer surface of the screw rod 36 to drive the groove rod 32 to slide on the outer surface of the sliding rod 33, adjust the overall length of the sliding rod 33 and the groove rod 32 and fix it. Then, insert the clamping blocks 34 at one end of the groove rod 32 and the clamping blocks 34 at one end of the sliding rod 33 into the clamping grooves 31 on one side of the upper and lower L-shaped rods 1 respectively, to support between the upper and lower L-shaped rods 1.
