Two wire entry holes 202 connected to the active cavity 201 are provided on the side wall of the base 20. The upper surface of the base 20 has a mounting plate 21, and a through hole 203 connected to the active cavity 201 is penetrated on the mounting plate 21. An elastic part 22 that moves up and down is integrally formed on the outer periphery of the through hole 203, and an oblique locking tooth 221 is provided at the outer end of the elastic part 22; in this embodiment, two second buckles 23 that cooperate with the two buckle holes 102 are provided at the lower end of the outer wall of the base 20, and the base 20 cooperates with the two buckle holes 102 through the two second buckles 23 Snapped onto the base 10; the three elastic parts 22 are arranged at equal angles, and an oblique locking tooth 221 is provided at the outer end of each elastic part 22. The multiple elastic parts 22 and the oblique locking teeth 221 can ensure the locking force between the knob 40 and the base 20, and the setting of the elastic part 22 is used to facilitate the positive rotation process of the knob 40; the upper and lower end surfaces of the inner wall of the through hole 203 are respectively provided with a first guide surface 24 and a second guide surface 25; the upper end of the outer side wall of the base 20 is integrally provided with an annular convex part 26 protruding outwardly; the side wall of the base 20 integrally extends outward with two wire entry parts 27, and the above-mentioned two wire entry holes 202 are arranged in the corresponding wire entry parts 27.

[0042] The capstan 30 can be rotatably arranged in the movable cavity 201, and the side wall of the capstan 30 is integrally provided with an annular winding groove 301 recessed inwardly, and a limiting column 31 is integrally extended upwardly from the upper end surface of the capstan 30, and a plurality of limiting grooves 302 are recessed inwardly around the periphery of the limiting column 31, and the limiting column 31 extends upward from the mounting plate 21 through the through hole 203; in this embodiment, the inner wall of the winding groove 301 is penetrated by a fixing hole 303 for fixing the end of the wire.

[0043] The knob 40 can be movably arranged on the base 20 up and down, and the lower end surface of the knob 40 is provided with an oblique gear plate 41 meshing with the oblique locking teeth 221. The engagement of the oblique gear plate 41 with the oblique locking teeth 221 allows the knob 40 to rotate in the forward direction. When the knob 40 rotates in the reverse direction, the oblique gear plate 41 will be locked with the oblique locking teeth 221, thereby achieving a locking effect. A plurality of elastic connecting plates 42 arranged in an annular manner and arranged at intervals are provided on the inner side of the oblique gear plate 41, each of which is arranged in an annular manner and arranged in an interval. The lower end of the elastic connecting plate 42 is integrally provided with a first buckle 421 protruding outward, and the first buckle 421 buckles into and leaves the through hole 203 as the knob 40 moves up and down; the inner side of each elastic connecting plate 42 is provided with a limiting portion 422 that cooperates with the limiting groove 302, and the limiting portion 422 is inserted into and away from the limiting groove 302 as the knob 40 moves, and extends downward into the limiting groove 302 through the limiting portion 422, so that when the knob 40 is rotated, the capstan 30 can be driven to rotate, thereby realizing the contraction and tightening process of the wire.

[0044] In this embodiment, the upper and lower end surfaces of the outer wall of the first buckle portion 421 are respectively provided with a third guide surface 423 and a fourth guide surface 424 that cooperate with the first guide surface 24 and the second guide surface 25. The cooperation between the first guide surface 24 and the third guide surface 423 and the cooperation between the second guide surface 25 and the fourth guide surface 424 facilitates the buckling process between the first buckle portion 421 and the inner wall of the through hole 203; the lower end of the knob 30 is convexly provided with a third buckle portion 43 that cooperates with the convex portion 26; the lower end surface of the knob 40 abuts against the wire feed portion 27; the cooperation between the third buckle portion 43 and the convex portion 26 is used to limit the upper movable position of the knob 40, and the wire feed portion 27 is used to limit the lower movable position of the knob 40; the outer peripheral side wall of the knob 40 is provided with an anti-slip surface 44, and the anti-slip surface 44 is used to prevent sliding when the user twists the knob.

[0045] The working principle of this embodiment is described in detail as follows:

[0046] When in use, it is necessary to first extend the two ends of the external wire into the winding groove 301 through the two wire entry holes 202 and fix them in the fixing holes 303. When the wire needs to be tightened, it is only necessary to press the knob 40 downward so that the limiting portion 422 extends downward into the limiting groove 302, and at the same time the oblique gear plate 41 is engaged with the oblique locking tooth 221. Then the knob 40 is turned forward. At this time, the knob 40 drives the capstan 30 to rotate, and the wire will be wound in the winding groove 301, thereby achieving the tightening process. When the wire is completely tightened, the knob can be loosened. At this time, the oblique locking teeth 221 and the oblique gear plate 41 will be stuck to prevent the knob 40 from rotating in the opposite direction. When the wire needs to be loosened, it is only necessary to pull the knob upward so that the first buckle portion 421 moves upward out of the through hole 203. At the same time, the oblique gear plate 41 moves upward away from the oblique locking teeth 221, and the limiting portion 422 moves upward away from the limiting groove 302. At this time, the wire can be pulled, thereby realizing the reverse rotation of the capstan 30, thereby realizing the process of loosening the wire.

[0047] The design focus of the utility model is that: a through hole connected to the movable cavity is passed through the mounting plate, an elastic part movable up and down is integrally formed on the outer periphery of the through hole, and an oblique locking tooth is arranged on the outer end of the elastic part; a limiting column is integrally extended upward from the upper end surface of the capstan, a plurality of limiting grooves are concave inwardly provided on the periphery of the limiting column, and an oblique gear plate meshing with the oblique locking teeth is arranged in cooperation with the lower end surface of the knob, a limiting part matching with the limiting groove is arranged on the inner side of each elastic connecting plate, so that the oblique locking teeth and the oblique gear plate realizing the locking function are respectively integrally formed on the base and the knob, and the limiting column and the limiting part realizing the contraction locking process are respectively integrally formed on the capstan and the knob, which reduces the number of parts and facilitates the assembly process, which not only improves the assembly efficiency, but also facilitates the disassembly and maintenance process.
