Description

Technical Field

[0001] The utility model relates to the technical field of screws, in particular to a torx screw. Background Art

[0002] Screws primarily connect and fasten two workpieces, making them one of the most basic and widely used fasteners. In related art, the most common screw groove is a cross-shaped one. If such screws are overtightened, they can slip when loosened. This slippage also wears the cross-shaped groove, making the screw impossible to remove. Utility Model Content

[0003] The purpose of the present invention is to provide a torx screw to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an internal hexagonal screw, comprising a screw head and a screw rod, the surface of the screw head is provided with a hexagonal hexagonal groove, and the inside of the hexagonal hexagonal groove is provided with an auxiliary groove. The hexagonal hexagonal groove and the auxiliary groove can be used to more stably screw the screw head, reduce the probability of slipping, and increase the friction between the screwdriver and the screw head. A stop block is sleeved on the screw rod, and the stop block is detachably connected to the screw head, thereby enriching the function of the screw.

[0005] Furthermore, a reinforcement block integrally formed with the screw head is provided on the surface of the screw head, and the hexagonal hexagonal slot extends to the reinforcement block. The reinforcement block increases the contact area between the screw head and the screwdriver, making it less likely to slip.

[0006] Furthermore, a slot is provided on the surface of the screw head, and a pin corresponding to the slot is inserted into the interior of the anti-rotation block, so that the anti-rotation block can be easily removed when it is not in use.

[0007] Compared with the prior art, the beneficial effects of the present invention are: the hexagonal hexagonal slot has more corners to clamp the screwdriver, and it is less likely to slip when using the screwdriver to tighten the screw. The auxiliary slot can further increase the contact area between the screw head and the screwdriver, making screwing more stable. A hexagonal wrench can also be used to tighten the screw, making screwing more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] Example:

[0015] See also Figure 1-4 The utility model provides a technical solution: an internal hexagonal screw, comprising a screw head 1 and a screw rod 5. The surface of the screw head 1 is provided with a hexagonal hexagonal groove 2, and an auxiliary groove 3 is provided inside the hexagonal hexagonal groove 2. The screw head 1 can be tightened using a screwdriver with a hexagonal hexagonal head and a hexagonal prism, or a hexagonal hexagonal screwdriver and a hexagonal wrench can be used alone. A stop block 7 is sleeved on the screw rod 5, and the stop block 7 is detachably connected to the screw head 1. When it is inconvenient to tighten the screw head 1, the screw will not be driven to rotate when the nut 11 is tightened.

[0016] In this embodiment, if Figure 1 and Figure 2 As shown, the surface of the screw head 1 is provided with a reinforcement block 4 integrally formed with the screw head 1, and the hexagonal hexagonal slot 2 extends to the reinforcement block 4. The reinforcement block 4 increases the depth of the hexagonal hexagonal slot 2, making it less likely to slip when using a hexagonal screwdriver to tighten the screw head 1.

[0017] In this embodiment, if Figure 3 As shown, a slot 6 is provided on the surface of the screw head 1, and a post 8 corresponding to the slot 6 is inserted into the anti-rotation block 7. The post 8 is separated from the slot 6, and the screw head 1 and the reinforcement block 4 can be separated.

[0018] In this embodiment, if Figure 1 As shown, the auxiliary groove 3 is hexagonal in shape, which makes it convenient to use a hexagonal wrench to tighten the screw head 1.

[0019] Specifically, when using, insert the plum screwdriver into the hexagonal plum slot 2 to turn the screw. The screw is not easy to slip when turning. If the plum screwdriver has a hexagonal prism, the hexagonal prism is inserted into the auxiliary slot 3, and the screw is even less likely to slip when turning.

[0020] A square groove 10 is provided on the surface of the workpiece 9. When the screw 5 passes through the workpiece 9, the stop block 7 is stuck in the square groove 10. The stop block 7 limits the rotation of the screw head 1 through the plug column 8. In a narrow space, when the screw head 1 cannot be tightened with a plum screwdriver, the nut 11 is screwed onto the screw 5. The stop block 7 limits the rotation of the screw 5 and can also fix the workpiece 9.

[0021] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
