[0022] The third shaft section 13 is the installation shaft. The third shaft section 13 is threadedly installed on the external slingshot through the second external thread 131. The present application can be installed on various forms of slingshots with internal threads. When installing the rubber band 5, the "8"-shaped ring 2, the pressure washer 3 and the hand-tightened nut 4 are all sleeved outside the second shaft section 12. Among them, the two rings of the "8"-shaped ring 2 have different diameters. The small ring 22 of the "8"-shaped ring 2 is sleeved outside the second shaft section 12, and the large ring 21 is away from the second shaft section 12. At this time, the flat rubber band 5 is passed through the upper end of the circular hole of the large ring 21 and then passed out from the bottom of the circular hole. Then, the "8"-shaped ring 2 is moved by hand so that the large ring 21 of the "8"-shaped ring 2 is sleeved outside the second shaft section 12 and the small ring 22 is away. On the second shaft section 12, move the "8"-shaped ring 2 upward so that the large ring 21 is sleeved outside the first shaft section 11, keeping the flat rubber band 5 protruding from the bottom of the circular hole in the large ring 21, and manually twist the hand nut 4, so that the hand nut 4 moves upward through the first external thread 121 and the first internal thread 41, driving the pressure washer 3 upward, and then moving the "8"-shaped ring 2 upward until the "8"-shaped ring 2 hits the top 10, so that the pressure washer 3 and the large ring 21 of the "8"-shaped ring 2 both squeeze the flat rubber band 5. When disassembling, manually twist the hand nut 4 downward to loosen the "8"-shaped ring 2, and move the large ring 21 of the "8"-shaped ring 2 downward to the outside of the second shaft section 12, so that the small ring 22 of the "8"-shaped ring 2 is sleeved outside the second shaft section 12, and the large ring 21 is away from the second shaft section 12. The old flat rubber band 5 can be manually removed and replaced with a new one. The pressure washer 3 squeezes the flat rubber band 5, and the large ring 21 of the "8"-shaped ring 2 squeezes the flat rubber band 5. After the flat rubber band 5 is installed, the component of the present application has two turns and is rigidly pressed, so that the flat rubber band 5 is installed very firmly. When assembling the rubber band 5, the "8"-shaped ring 2 moves outward, so that the large ring 21 is away from the second shaft section 12, which is convenient for installing the flat rubber band 5. The current slingshot mainly assembles the flat rubber band 5 by tying it with a rope, or requires other tools, such as a screwdriver, a rope, etc. The disadvantages are: first, some methods make it difficult to insert the flat rubber band, which is troublesome and time-consuming; second, it is unstable and easy to be pulled out, which may cause danger. The component of the present application does not require any other tools when installing the flat rubber band, and can be completed by hand, which is particularly convenient.

[0023] The present invention is a component that enables the rapid installation of a flat rubber band 5 on a slingshot. This component facilitates the rapid installation and removal of the flat rubber band 5 by hand without the aid of other tools during the use of the slingshot. The rubber band 5 can be quickly replaced while ensuring a secure installation. The present invention provides a simple and stable fixing method, enabling the rapid installation and replacement of the flat rubber band 5 while ensuring a secure installation. The present invention is also applicable to devices requiring the installation of a flat rubber band 5.

[0024] Furthermore, the assembly includes a pressure washer 3 disposed between the "8"-shaped ring 2 and the thumb nut 4. This protects the surface of the "8"-shaped ring 2 from scratches caused by the thumb nut 4, thereby increasing the service life of the "8"-shaped ring 2. The thickness of the "8"-shaped ring 2 is greater than that of the first shaft section 11, ensuring that the pressure washer 3 and thumb nut 4 are securely mounted on the second shaft section 12.

[0025] Furthermore, a through hole 111 is provided on the first shaft section 11, and the through hole 111 can facilitate a small screwdriver or other small metal rod to pass through the through hole 111. When the small screwdriver or other small metal rod is rotated, an internal thread is provided on the external slingshot to cooperate with the second external thread 131, so that the third shaft section 13 is threadedly installed on the slingshot with a corresponding internal thread through the second external thread 131. The present application can be installed on various forms of slingshots with corresponding internal threads; when the component of the present application is installed on the slingshot, first install the "8"-shaped ring 2, The pressure washer 3 and the hand-tightening nut 4 are put on the support head column 1 from top to bottom, and then the second external thread 131 on the support head column 1 is preliminarily connected with the corresponding internal thread on the slingshot, and then a small screwdriver or other small metal rod is passed through the through hole 111, and the small screwdriver or other small metal rod is rotated to install the second external thread 131 of the support head column 1 on the slingshot; in this way, there is no need to repeatedly disassemble the components of the present application, and only the "8"-shaped ring 2, pressure washer 3 and hand-tightening nut are needed to complete the installation or removal of the flat or strip rubber band 5.

[0026] Furthermore, the outside of the hand nut 4 is provided with anti-slip grooves 42 , and the anti-slip grooves 42 make it convenient for the user to manually tighten the hand nut 4 .

[0027] Furthermore, in order to prevent the "8"-shaped ring from falling off, the top 10 is circular, and the diameter of the top 10 is larger than the inner diameter of the large ring 21 of the "8"-shaped ring 2. The larger top 10 makes it easier for the "8"-shaped ring 2 to press the flat rubber band 5 upward.

[0028] Furthermore, the supporting column 1, the "8"-shaped ring 2, the pressure washer 3 and the hand-tightening nut 4 are all made of metal.
