[0067] In this embodiment, the fastening device 10 is an open structure, and the first magnetic member 150 and the second magnetic member 230 are magnetically connected to enable the rotating assembly 100 and the base assembly 200 to be detachably connected, so that the belt-shaped member 22 on the object 20 can be opened or buckled in an open manner. The rotating assembly 100 and the base assembly 200 after buckling can adjust the tightness of the belt-shaped member 22 by rotating the rotating member 101. In addition, in this embodiment, when the rotating assembly 100 and the base assembly 200 need to be buckled, the magnetic connection between the first magnetic member 150 and the second magnetic member 230 can also achieve rapid positioning between the two, which is convenient for users to operate.

In this embodiment, the mounting groove 211 is opened on the protrusion 212, so that the second magnetic member 230 is closer to the first magnetic member 150 on the rotating member 101 after being installed in the mounting groove 211, which facilitates the magnetic connection and positioning of the first magnetic member 150 and the second magnetic member 230.

[0072] Combination Fig.12 As shown, in the above embodiment of the protrusion 212, for example, the height of the protrusion 212 along the first direction z is less than the depth of the slide groove 220. In this way, it is avoided that the protrusion 212 is too high, causing interference between the base body 210 and the sliding seat 102 after being connected by the magnetic member, resulting in difficulty in relative sliding.

[0073] In another embodiment, this embodiment is different from the above-mentioned solution with the protrusion 212 . Exemplarily, the mounting groove 211 is formed by the bottom surface of the base body 210 being recessed into the slide groove 220 .

[0074] like Fig.11 and Fig.12 As shown, in another embodiment, the mounting groove 211 is a stepped hole groove, which includes a first hole segment 2111 and a second hole segment 2112.

When the sliding seat 102 moves relative to the base body 210, the hooking portion 1023 can abut against the limiting portion 223 and can move along the second direction x. The limiting portion 223 is used to limit the sliding seat 102 from moving along the first direction z. In this embodiment, the cooperation between the limiting portion 223 and the hooking portion 1023 prevents the sliding seat 102 from shaking in the first direction z when sliding relative to the base body 210. At the same time, the cooperation between the hooking portion 1023 and the limiting portion 223 is also equivalent to the guiding function of the slide rail, which facilitates the sliding seat 102 to slide relative to the base body 210.

When the rotating cover 120 rotates along the second preset rotation direction, the first clamping portion 1421 is disengaged from the first tooth groove 112, the second clamping portion 1431 is clamped with the second tooth groove 132, and the transmission member 110 is freely rotated around its rotation axis, and the sliding seat 102 can be moved relative to the base body 210 by pulling the belt-shaped member 22 or the sliding seat 102, so that the belt-shaped member 22 is loosened.

[0106] It should be noted that the first preset rotation direction is opposite to the second preset rotation direction. In this embodiment, the first preset rotation direction is taken as a clockwise direction and the second preset rotation direction is taken as a counterclockwise direction. Of course, in other embodiments, the first preset rotation direction may be a counterclockwise direction and the second preset rotation direction may be a clockwise direction.
