Problems solved by technology

[0003] When the above-mentioned existing screws are used as fasteners to fix the surface parts of the product, the driving head protrudes from the surface of the product, and its style is inconsistent with the surface parts of the product.
Moreover, it inserts a screwdriver into the drive groove on the drive head to operate the screw. When tightening or loosening the screw, it may slip or the drive head slips, causing the screwdriver to lose control during operation, thereby scratching the surface of the part and further affecting The appearance of the product, and even make the surface parts of the product scrapped
[0004] In addition, the screw structure needs to use different types of screwdrivers to operate the screws of different driving groove types; Equipped with a large number of screwdrivers of different types and specifications, the tools are complicated, the operation is inconvenient, and the cost is high

Abstract

The invention discloses a screw structure and a screw driving device. The screw body comprises a threaded part and a driving part. The end face of the outer side of the screw body is the driving part. The screw driving device comprises a sucker, a shaft lever and a driving mechanism driving the shaft lever to rotate. According to the screw structure, the attractiveness of a product can be greatly improved, the surface attractiveness of the screw can be effectively protected through the screw driving device, and universality and applicability of the screw driving device are extremely high.

Description

technical field [0001] The invention relates to a screw structure and a screw driving device for driving the screw. Background technique [0002] A screw is a connecting fastener such as figure 1 As shown, it includes a threaded end 101 at the bottom and a hat-shaped driving head 102 protruding from the top. Depending on the type of screw, the hat-shaped driving head can be provided with different driving grooves such as slots, cross grooves, or inner hexagonal grooves. Usually The outer diameter of the driving head is larger than that of the stud, which is used to compress and fix the profile. When tightening the screws, you need to use a flat-blade screwdriver, Phillips screwdriver, or hexagonal screwdriver corresponding to the drive slot and other driving tools. [0003] When the above-mentioned existing screws are used as fasteners to fix the surface parts of the product, the driving head protrudes from the surface of the product, and its style is inconsistent with the...
