[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-5 As shown, an internal plum blossom countersunk head tail-cut screw includes a screw 1, a head 2 fixedly connected to the top of the screw 1, a placement groove 3 is provided on one side of the head 2, an installation block 4 is provided in the placement groove 3, a plurality of connecting grooves 6 are provided on one side of the placement groove 3, the plurality of connecting grooves 6 are evenly distributed in an array, a plurality of connecting blocks 7 are fixedly connected to the edge of the installation block 4, the plurality of connecting blocks 7 are evenly distributed in an array, and one end of each of the plurality of connecting blocks 7 extends into the plurality of connecting grooves 6.

[0024] In this embodiment, a first embedding groove 8 is provided on one side of each of the several connecting grooves 6, and a first magnet 9 is fixedly connected in the first embedding groove 8. A second embedding groove 10 is provided on one side of each of the several connecting blocks 7, and a second magnet 11 is fixedly connected in the second embedding groove 10.

[0025] First, align the connecting block 7 with the connecting groove 6 and press it into the connecting groove 6. Then, place the mounting block 4 into the placement groove 3 opened in the head 2. The first magnet 9 in the first embedding groove 8 and the second magnet 11 in the second embedding groove 10 attract each other, fixing the mounting block 4 in the placement groove 3. This connects the mounting block 4 to the head 2, allowing the screw 1 to rotate. When the twisting groove on the mounting block 4 is damaged, remove the mounting block 4 and install a new one, allowing the screw 1 to rotate. This solves the problem of the screwdriver not being able to effectively engage the screw groove after it is damaged, thus preventing the installation process from becoming difficult, ensuring that the screw can be tightened or disassembled, improving the safety of the equipment, avoiding accidents, reducing user losses, and greatly increasing the practicality of the equipment.

[0026] Meanwhile, a plum blossom groove 5 is provided on one side of the mounting block 4. The plum blossom groove 5 makes it convenient for workers to rotate the screw 1, making it easy for workers to use.

[0027] Both the first magnet 9 and the second magnet 11 are strong magnets. The first magnet 9 and the second magnet 11 attract each other. By using strong magnets, the attraction between the first magnet 9 and the second magnet 11 is increased, which greatly increases the reliability of the connection between the mounting block 4 and the head 2.

[0028] In this embodiment, a cover plate 12 is fixedly snapped into the opening of the second embedding groove 10.

[0029] The second magnet 11 is protected by the cover plate 12, which prevents the second magnet 11 from being exposed to the outside and thus avoids damage to the second magnet 11.

[0030] In this embodiment, a fixing block 13 is fixedly connected to one side of the cover plate 12, and a through groove 14 is provided on the fixing block 13.

[0031] The rod passes through the slot 14 and is used in conjunction with the fixing block 13 to facilitate the removal of the mounting block 4 from the placement slot 3. This makes it easy to replace the damaged mounting block 4, greatly increasing the convenience of the equipment and making it easier for staff to use, thus improving the user experience.

[0032] In this embodiment, two sets of positioning holes 15 are provided on one side of the mounting block 4. The two sets of positioning holes 15 are symmetrically distributed about the central axis of the mounting block 4. Two sets of positioning rods 16 are fixedly connected to one side of the placement groove 3. The other end of the two sets of positioning rods 16 extends into the positioning hole 15.

[0033] When the mounting block 4 is placed in the placement slot 3, the positioning rod 16 is inserted into the positioning hole 15 to increase the strength of the mounting block 4 when it drives the screw 1 to rotate, making it easier for the mounting block 4 to drive the screw 1 to rotate, thus facilitating the use of the screw 1, and at the same time increasing the stability of the screw 1 when it rotates.

[0034] It should be noted that this utility model is an internal Torx countersunk head screw with a ferrule cut-off end. In use, the connecting block 7 is aligned with the connecting groove 6 and pressed into the connecting groove 6. At the same time, the positioning rod 16 is inserted into the positioning hole 15 to increase the strength when the mounting block 4 drives the screw 1 to rotate. The mounting block 4 is placed in the placement groove 3 opened in the head 2. The first magnet 9 in the first embedded groove 8 and the second magnet 11 in the second embedded groove 10 attract each other, fixing the mounting block 4 in the placement groove 3 and connecting the mounting block 4 with the head 2. Then the screw 1 can be rotated. When the torsion groove on the mounting block 4 is damaged, the rod is used to pass through the through groove 14 and cooperate with the fixing block 13 to pull the mounting block 4 out from the placement groove 3. Then a new one is installed, and the screw 1 can be rotated.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
