[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] As shown in the figures: Figure 1 , the figures: Figure 3 , and the figures: Figure 4As shown, a high-strength anti-slip wire roof screw includes a mounting plate 1, a screw 2, and a U-shaped frame 3. The screw 2 slides through the mounting plate 1, and the U-shaped frame 3 is located on the lower side of the mounting plate 1. A threaded sleeve 4 is provided at the center of the bottom of the U-shaped frame 3. The screw 2 passes through the threaded sleeve 4 and is threadedly connected. By rotating the screw 2, the U-shaped frame 3 is moved upward, and the two side walls of the U-shaped frame 3 are pressed against the lower side of the mounting plate 1. Anti-slip textures 9 are provided on the upper side of the two side walls of the U-shaped frame 3. The anti-slip textures 9 are in contact with the lower side of the mounting plate 1 to prevent the U-shaped frame 3 from sliding on the lower side of the mounting plate 1.

[0023] As attached Figure 1 and attached Figure 4 As shown, a positioning component is provided between the inner side of the U-shaped frame 3 and the mounting plate 1. The positioning component includes two sets of insertion rods 5, which are installed on the inner side of the bottom of the U-shaped frame 3. The mounting plate 1 is provided with two sets of through holes 6 for the insertion rods 5 to slide through, so as to prevent the U-shaped frame 3 from rotating with the screw 2 and causing the screw 2 to loosen.

[0024] As attached Figure 1 and attached Figure 2 As shown, a washer 7 is slidably fitted on the outside of the screw 2. The washer 7 is made of metal and its axis coincides with the axis of the screw 2. The washer 7 is located between the top of the screw 2 and the mounting plate 1. The washer 7 is provided with two sets of insertion holes 8 for inserting the insert rod 5. The insert rod 5 is inserted into the insertion hole 8 to limit the washer 7 and prevent the washer 7 from shaking.

[0025] The specific usage method is as follows:

[0026] Holes for screws 2 and through holes for insert rods 5 are made in the mounting plate 1. The U-shaped frame 3 is placed on the underside of the mounting plate 1. The two sets of insert rods 5 are passed through the corresponding through holes 6. Screws 2 pass through the mounting plate 1 and threaded sleeves 4. By rotating screws 2, the threaded sleeves 4 and U-shaped frame 3 are moved upward, so that the upper sides of the two side walls of the U-shaped frame 3 come into contact with the lower side of the mounting plate 1 and are tightly pressed against the lower side of the mounting plate 1. The roof connector is attached to one side of the mounting plate 1. Screws 2 pass through the roof connector and the mounting plate 1 to fix the roof connector to the mounting plate 1.

[0027] When the mounting plate 1 is relatively thin, a washer 7 is fitted on the outside of the screw 2, and the insertion rod 5 is inserted into the insertion hole 8 to position the washer 7. The washer 7 also strengthens the clamping strength between the connector and the mounting plate 1.
