The double - headed self - tapping screw is arranged inside the U - shaped frame. Mounting holes are opened on both the left and right sides of the middle part of the outer side wall of the double - headed self - tapping screw. The two mounting holes are symmetrically arranged. The left inner wall and the right inner wall of the U - shaped frame are rotatably provided with rotating shafts. The two rotating shafts are symmetrically arranged. The two rotating shafts are respectively inserted into the two mounting holes. The rotating shafts are axially slidably matched with the mounting holes. Two jacks are opened on both the left and right sides of the outer side wall of the double - headed self - tapping screw. The four jacks are distributed in a square matrix. Compared with the prior art, it can install the self - tapping screw conveniently and quickly, effectively prevent the double - headed self - tapping screw from being worn or deformed, has a simple structure, is easy to use, and is convenient for popularization and application;

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 3 , an anti-deformation double-headed self-tapping screw, including a double-headed self-tapping screw 13. A set of locking holes 2 are opened on the left and right sides of the middle part of the outer side wall of the double-headed self-tapping screw 13. Among them: An anti-deformation component is sleeved on the top of the outer side wall of the double-headed self-tapping screw 13, and a fixing component is placed on the outer ring of the anti-deformation component. The anti-deformation component includes a second sleeve 12. A cross groove 22 is opened at the top of the second sleeve 12. The outer ring of the second sleeve 12 is sleeved with a first sleeve 1. A set of insertion holes 21 are penetrated through the left and right sides of the second sleeve 12. Two sets of limit rings 11 are evenly and fixedly arranged on the outer side wall of the second sleeve 12. The first sleeve 1 is located between the two sets of limit rings 11, and the position of the first sleeve 1 is limited by the limit rings 11. The second sleeve 12 is sleeved on the top of the outer side wall of the double-headed self-tapping screw 13, and the insertion holes 21 correspond to the locking holes 2. The fixing component includes a third sleeve 14. A set of through holes are penetrated through the left and right sides of the third sleeve 14. Plugs 15 are inserted into the through holes. A set of connection plates 16 are fixedly arranged on the opposite sides of the two plugs 15. A set of handles 17 are fixedly arranged on the opposite sides of the two connection plates 16. The second sleeve 12 is located between the two connection plates 16. A spring 18 is placed on the outer ring of the plug 15. The spring 18 is fixedly arranged between the connection plate 16 and the third sleeve 14. The third sleeve 14 is sleeved on the outer ring of the second sleeve 12, and the plug 15 corresponds to the insertion holes 21 and the locking holes 2.

[0022] Working principle: Slide the second sleeve 12 downward along the top of the double-headed self-tapping screw 13. When the jack 21 is aligned with the locking hole 2, slide the third sleeve 14 downward to drive the bolt 15 to move downward. When the bolt 15 is aligned with the jack 21, the spring 18 uses its own resilience to drive the bolt 15 through the jack 21 and insert it into the locking hole 2 through the connecting plate 16, thereby fixing the locking hole 2 in the second sleeve 12. At this time, insert a cross screwdriver into the cross groove 22 and rotate it. At this time, the worker holds the first sleeve 1 and the device can be stabilized, and the first sleeve 1 will not rotate with the rotation of the second sleeve 12. Then, the second sleeve 12 can be used to drive the double-headed self-tapping screw 13 to rotate, thereby driving the double-headed self-tapping screw 13 to perform self-tapping work. And when the double-headed self-tapping screw 13 rotates, the thread at the top of the outer wall of the double-headed self-tapping screw 13 does not rub against other components, thereby protecting the thread of the double-headed self-tapping screw 13 and preventing the thread at the other end of the double-headed self-tapping screw 13 from being damaged and deformed during use. When the double-headed self-tapping screw 13 is installed, pull the handle 17 outward to drive the bolt 15 to separate from the locking hole 2. At this time, the handle 17 can be moved upward to drive the locking hole 2 to move upward and separate from the double-headed self-tapping screw 13.
