[0006] Through the above solution, since cutting the wall-piercing screw, as well as the concrete chiseling and leveling operations before and after cutting, are laborious, increasing the workload of workers, reducing work efficiency, and the screw is difficult to be reused, resulting in waste of resources, by setting the threaded sleeve and the screw, after the formwork is removed, the screw can be directly taken out from inside the threaded sleeve for reuse, without the need for cutting and leveling, saving costs, and reducing the construction workload. By setting the inserting rod, the jack and the spring, the screw is restricted, increasing the stability of the connection between the screw and the threaded sleeve.

[0007] Further, a collar is fixedly sleeved on the outer circumferential surface of each inserting rod, the outer circumferential surface of the collar is slidably connected to the inside of the threaded sleeve, the bottom surface of the collar is fixedly connected to a spring, and the bottom end of the spring is fixedly connected to the inside of the threaded sleeve.

[0009] Furthermore, two plugs are fixedly sleeved on the outer circumferential surface of the threaded sleeve, and the two plugs are symmetrically distributed.

[0010] Through the above solution, the plugs can play a role in limiting the threaded sleeve, thereby increasing the stability of the threaded sleeve.

[0011] Furthermore, a mountain-shaped clamp is threadedly connected to the outer circumferential surface of each screw rod, and four water stop pads are slidably sleeved on the outer circumferential surface of the threaded sleeve.

[0012] Through the above solution, the mountain-shaped clamp can position the external formwork and play a role in fastening the formwork, and the water stop pads can block water and mud, preventing water and mud from seeping in.

[0013] Furthermore, a fastening ring is provided on the outer circumferential surface of each screw rod, and the fastening rings are respectively located between the mountain-shaped clamp and the water stop pads.

[0014] Through the above solution, the fastening ring can press the water stop pad tightly, optimizing the sealing effect of the water stop pad.

[0015] Furthermore, two nuts are threadedly connected to the outer circumferential surface of each screw rod, and the two nuts are in contact with each other.

[0016] Through the above solution, the nuts can limit the mountain-shaped clamp, preventing the mountain-shaped clamp from easily moving back, and increasing the stability of the mountain-shaped clamp.

[0017] Furthermore, a dial is fixedly connected to the outer circumferential surface of the collar, and the outer surface of the dial is slidably connected to the inside of the threaded sleeve.

[0018] Through the above solution, the collar and the plug rod can be lifted by the dial, preventing obstacles to the screw rod during the installation of the screw rod.

[0019] Furthermore, a partition is fixedly connected to the inner wall of the threaded sleeve, and both sides of the partition are respectively in contact with the outer surface of the screw rod.

[0020] Through the above solution, the screw rod is restricted, prompting the length of the connection between the screw rod and the threaded sleeve to be fixed, and further making the positions of the plug rod and the jack corresponding when the screw rod is completely installed inside the threaded sleeve.

[0021] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0022] The basement wall-piercing screw, by setting the threaded sleeve and the screw, enables the screw to be directly taken out from the inside of the threaded sleeve after the formwork is removed, and can be reused without cutting and patching, saving costs and reducing the construction workload. By setting the insertion rod, the insertion hole and the spring, the screw is restricted, and the stability of the connection between the screw and the threaded sleeve is increased, solving the problems that cutting the wall-piercing screw, and the concrete chiseling and patching operations before and after cutting are laborious, increasing the workload of workers, reducing the operation efficiency, and the screw is difficult to reuse, resulting in waste of resources.

The outer circumferential surface of the collar 5 is slidably connected to the inside of the threaded sleeve 1. The bottom surface of the collar 5 is fixedly connected to a spring 6. The bottom end of the spring 6 is fixedly connected to the inside of the threaded sleeve 1. The spring 6 can exert a reaction force on the collar 5 and the insertion rod 3, prompting the insertion rod 3 to insert into the insertion hole 4 to position the screw rod 2 and prevent the screw rod 2 from easily rotating back and moving, thereby increasing the stability of the connection between the screw rod 2 and the threaded sleeve 1.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 , two plugs 8 are fixedly sleeved on the outer circumferential surface of the threaded sleeve 1. The two plugs 8 are symmetrically distributed. The plugs 8 can limit the threaded sleeve 1, thereby increasing the stability of the threaded sleeve 1.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 , a mountain-shaped clamp 9 is threadedly connected to the outer circumferential surface of each screw rod 2. Four water-stop pads 10 are slidably sleeved on the outer circumferential surface of the threaded sleeve 1. The mountain-shaped clamp 9 can position the external formwork and play a role in fastening the formwork. The water-stop pads 10 can block water and mud and prevent water and mud from seeping in.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 , a fastening ring 11 is provided on the outer circumferential surface of each screw rod 2. The fastening rings 11 are respectively located between the mountain-shaped clamp 9 and the water-stop pad 10. The fastening rings 11 can press the water-stop pads 10 tightly to optimize the sealing effect of the water-stop pads 10.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 , two nuts 12 are threadedly connected to the outer circumferential surface of each screw rod 2. The two nuts 12 are in contact with each other. The nuts 12 can limit the mountain-shaped clamp 9 and prevent the mountain-shaped clamp 9 from easily moving back, thereby increasing the stability of the mountain-shaped clamp 9.

[0036] Please refer to Figure 2 , Figure 3 and Figure 4 , a dial 13 is fixedly connected to the outer circumferential surface of the collar 5. The outer surface of the dial 13 is slidably connected to the inside of the threaded sleeve 1.

[0039] It should be noted that both of the two plugs 8 are in a conical structure.

[0040] The working principle of the above embodiment is as follows:

[0041] When the screw rod 2 and the threaded sleeve 1 need to be installed, lift the dial 13. The dial 13 drives the insertion rod 3 to lift through the collar 5 and stretches the spring 6. Then rotate the screw rod 2 and install it inside the threaded sleeve 1. When the screw rod 2 contacts the partition 14, the screw rod 2 is completely installed inside the threaded sleeve 1. At this time, the positions of the insertion rod 3 and the insertion hole 4 correspond to each other. Release the hand that lifts the dial 13, and the insertion rod 3 moves back under the reaction force of the spring 6 and inserts into the insertion hole 4, then the installation positioning of the screw rod 2 can be completed, increasing the stability of the connection between the screw rod 2 and the threaded sleeve 1. The formwork can be installed between the U-shaped clip 9 and the fastening ring 11. When the formwork is removed later, the nut 12, the U-shaped clip 9, the formwork, the fastening ring 11, and the water stop 7 can be removed in sequence. Then lift the dial 13 to make the insertion rod 3 move out of the insertion hole 4, and then rotate and remove the screw rod 2 for reuse without cutting and patching, saving costs and reducing the construction workload.
