Abstract

The invention provides a fastening device. The fastening device comprises a shell unit, a wire coil, a detent unit, a rotary knob and a connecting unit, wherein the shell unit comprises an annular wall, and the annular wall surrounds an inner space; the wire coil is located in the inner space and comprises an axis space, the axis space comprises a large-diameter section and a small-diameter section, and the small-diameter section is connected with the large-diameter section in the axial direction; the detent unit is arranged above the wire coil in the axial direction; and the rotary knob is arranged above the detent unit in the axial direction, and the rotary knob is coupled to the detent unit. The connecting unit comprises a first component set and a second component set, the first component set is connected with the rotary knob, the second component set penetrates through the axis space to be connected with the first component set, and the second component set is limited by the large-diameter section. Therefore, the structural reliability is improved.

Description

technical field [0001] The present invention relates to a fastening device, and in particular to a fastening device capable of retracting and releasing a tie line. Background technique [0002] In daily life, thread bodies such as ropes and laces are often used to bind objects. The most common means of containment is to use thread bodies to shuttle back and forth through holes in objects, and then fix them with knots, such as rope-tying shoes and so on. However, this kind of constriction method is easy to cause the knot to loosen due to external force factors, not only must the knot be re-tied, but also brings a lot of inconvenience because of the inability to securely confine the object. [0003] In order to solve this kind of problem, some operators have developed a simple wire harness mechanism, which includes a housing, a detent unit and a spring. The active force makes the wire body be clamped between the braking unit and the housing to achieve a fastening effect, and ...
