[0022] In the following, embodiments of the adjustable fastener of the present invention will be described with reference to the accompanying drawings.
[0023] Figures 1-3 An adjustable fastener showing an embodiment of the present invention includes a tubular deformable fastening strip 1: A front joint 2 is fixedly connected to the front side of the tubular deformable fastening strip 1, a rear joint 3 is fixedly connected to the rear side of the tubular deformable fastening strip 1, an adjusting fastening strip 4 is slidably connected to the inner cavity of the tubular deformable fastening strip 1, the front end of the adjusting fastening strip 4 passes through the inner cavity of the front joint 2 and extends to the outside of the front joint 2, a barb 5 is fixedly connected to the right side of the adjusting fastening strip 4, a locking plate 6 for cooperating with the barb 5 is installed in the inner cavity of the rear joint 3, a mounting block 14 is fixedly connected to the inner cavity of the rear joint 3, the locking plate 6 is rotatably connected to the surface of the mounting block 14 through a torsion spring, and through the rotational connection setting of the locking plate 6, when disassembling the fastener, the locking plate 6 can be rotated to release the locking of the locking plate 6 on the barb 5, so as to facilitate the user to draw out the adjusting fastening strip 4 from the inner cavity of the rear joint 3, enabling the fastener to be reused multiple times. A slide block 7 is fixedly connected to the bottom of the adjusting fastening strip 4, slide grooves 8 for cooperating with the slide block 7 are formed at the bottoms of the inner cavities of the front joint 2 and the rear joint 3. Through the cooperation of the slide block 7 and the slide groove 8, when the adjusting fastening strip 4 is drawn out for use, the slide block 7 will slide in the inner cavity of the slide groove 8, thereby improving the sliding stability of the adjusting fastening strip 4. Teeth 9 are formed on the left side of the adjusting fastening strip 4, a gear 11 is rotatably connected to the inner cavity of the front joint 2 through a rotating shaft 10, the gear 11 is fixedly connected to the surface of the rotating shaft 10, the rotating shaft 10 is rotatably connected to the inner cavity of the front joint 2 through a torsion spring, the gear 11 meshes with the teeth 9, the top plate of the rotating shaft 10 extends to the outside of the front joint 2 and is fixedly connected to a ratchet wheel 12, and a pawl 13 for cooperating with the ratchet wheel 12 is rotatably connected to the top plate of the front joint 2 through a torsion spring. Through the cooperation of the ratchet wheel 12 and the pawl 13, the rotation of the rotating shaft 10 can be locked, preventing the torque of the teeth 9 on the adjusting fastening strip 4 on the gear 11 from being too large, which may cause the rotating shaft 10 to rotate and affect the drawn length of the adjusting fastening strip 4. A fixed plate 15 is fixedly connected to the rear side of the tubular deformable fastening strip 1, and a plurality of springs 16 are fixedly connected between the fixed plate 15 and the adjusting fastening strip 4.
