Description

Technical Field

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

[0002] Screws are tools that use the physics and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually fasten objects and mechanical parts. Screws are a general term for fasteners. Screws are indispensable industrial necessities in daily life: such as very small screws used in cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; as for engineering, construction, and bridges, large screws and nuts are used; transportation equipment, airplanes, trams, cars, etc. use both large and small screws. Screws have important tasks in industry, and as long as there is industry on the earth, the function of screws will always be important.

[0003] If the existing screws are too long, improper operation during the screwdriver operation may cause the screws to not be driven straight into the object to be fastened. Especially when the screws need to be driven in at an inclined angle, if there is no support on both sides, the screws will be driven crooked or not in the best position, which may affect the connection quality. In addition, long screws are prone to produce more waste during use. If the accumulated waste cannot be cleaned up, it will bring certain resistance to the tapping wire and affect the worker's operation. Utility Model Content

[0023] Furthermore, a stopper 12 is disposed on the outer wall of the screw head 3 , and the outer diameter of the stopper 12 is greater than the inner diameter of the nut 2 .

[0024] Furthermore, a holding plate 6 is provided at the bottom of the outer wall of the nut 2. The holding plate 6 is horizontally arranged along the bottom of the outer wall of the nut 2 and is perpendicular to the screw column 1. A sealing layer 13 is fixedly provided at the bottom of the holding plate 6. The sealing layer 13 is made of rubber material.

[0025] Furthermore, a buffer pad 14 is provided at the bottom of the stopper 12 , and the buffer pad 14 is made of rubber material.

[0026] Furthermore, the second notch 10 is formed on the screw column 1 and is located on the side wall below the screw head 3 , and an arc-shaped pipe 15 is provided between the second notch 10 and the slot body 11 .

[0027] In the embodiment of the present utility model, please refer to Figure 1-Figure 4In the direction of drilling the screw column 1, when the screw column 1 is too long, especially when the screw needs to be driven in obliquely or horizontally, the screw is not easy to hold, and the screw may be driven crooked or not driven in the best position during the operation of the screwdriver, which may affect the connection quality. When the screw column 1 needs to be driven in, the nut 2 is located above the drill bit 7. At this time, the staff only needs to press the hand on the gripping plate 6. Since the gripping plate 6 is horizontally arranged along the bottom of the outer wall of the nut 2 and the gripping plate 6 is perpendicular to the screw column 1, the gripping plate 6 can fit the working surface. At the same time, since the nut 2 is threadedly connected to the screw column 1, the screw column 1 is provided with a force perpendicular to the screw column 1, which can effectively support the screw column 1 and prevent the screw column 1 from tilting during the driving process. At this time, you only need to keep your hand on the gripping plate 6 to keep the gripping plate 6 in contact with the working plane, and then use the screwdriver to drive the screw until the screw head 3 is close to the nut 2. At this time, the connection work is completed. The outer wall of the screw head 3 is provided with a stopper 12 , the outer diameter of which is larger than the inner diameter of the nut 2 , so as to prevent the nut 2 from falling off.

[0028] See also Figure 1-Figure 4 The bottom of the screw column 1 is provided with a tapping part, the tapping part includes a drill bit 7 and a chip groove 8, the chip groove 8 includes a first notch 9, a second notch 10 and a groove body 11, the first notch 9 is provided at the bottom of the screw column 1 and is located above the drill bit 7, the first notch 9 is connected to the thread of the drill bit 7, the groove body 11 of the chip groove 8 is vertically opened inside the screw column 1, the second notch 10 is provided at the top of the screw column 1 and is located below the screw head 3, the first notch 9 is connected to the bottom end of the groove body 11, and the second notch 10 is connected to the top end of the groove body 11 When tapping, waste chips are first generated by the drill bit 7, enter the first slot 9 through the chip removal groove 8, and then enter the slot body 11 through the first slot 9. The slot body 11 is vertically opened inside the screw column 1 to reduce the resistance of waste chips entering. When there are not many waste chips, the waste chips will accumulate inside the slot body 11. When there are more waste chips, they will be discharged through the second slot 10. An arc pipe 15 is provided between the second slot 10 and the slot body 11. The arc pipe 15 can accelerate the discharge of waste chips and prevent waste chips from accumulating near the second slot 10. When the screw driving work is completed, the nut 2 will be close to the lower part of the screw head 3. At this time, the nut 2 seals the second slot 10 to prevent waste chips from falling, and prevents raindrops from entering the second slot 10 and corroding the waste chips inside.
