That is, the second magnetic member 201 is fixedly mounted on the bottom of the seat body 200 .

[0066] like Figure 3 As shown, in the above embodiment, illustratively, a step structure 220 is provided on the base 200, and the mounting groove 210 is located at the step structure 220. Correspondingly, a step structure is provided on the retractable wire mechanism 100, so that after the base is connected to the retractable wire mechanism 100, the step structure 220 of the base and the step structure of the retractable wire mechanism 100 are interlocked with each other, which can prevent the first magnetic member 101 and the second magnetic member 201 from being easily offset in the length direction of the base 200 when the magnetic connection is made.

[0067] Exemplarily, the step structure 220 includes a first step 221 and a second step 222 connected to the first step 221, a portion of the mounting groove 210 is located at the first step 221, and another portion of the mounting groove 210 is located at the second step 222. In this way, the second magnetic member 201 installed and fixed in the mounting groove 210 can be connected to the first magnetic member 101 at both steps of the step structure 220.

[0068] Exemplarily, the groove wall of the mounting groove 210 located at the second step 222 protrudes from the stepped surface of the second step 222 .

[0069] exist Figure 3 In the embodiment, at least one first clamping portion 230 is formed on the seat body 200 along the edge of the second step 222 extending in a direction away from the second step 222. The first clamping portion 230 is used to clamp with the wire-retracting and unwinding mechanism 100 and does not limit the magnetic connection between the second magnetic member 201 and the first magnetic member 101, thereby ensuring the connection strength between the seat body 200 and the wire-retracting and unwinding mechanism 100. At the same time, the clamping design of the first clamping portion 230 and the wire-retracting and unwinding mechanism 100 cannot limit the unfastening action when the first magnetic member 101 and the second magnetic member 201 are separated.

[0070] exist Figure 1 and Figure 3 In one embodiment, the fastening device 10 has a first direction x and a second direction y perpendicular to the first direction x, there are two first clamping parts 230, and the two first clamping parts 230 are arranged at intervals along the second direction y, the first direction x is the length direction of the belt body 22 connected to the seat body 200, that is, the length direction of the seat body 200, and the second direction y is the width direction of the belt body 22, that is, the width direction of the seat body 200. Since the first magnetic member 101 is located in the middle of the retractable line mechanism 100, and the second magnetic member 201 is also located in the middle of the seat body 200, the two first clamping parts 230 are arranged at intervals to increase the balance when the seat body 200 and the retractable line mechanism 100 are engaged.

[0071] In the above Figure 3 In the embodiment, a notch 231 is defined between the two first clamping parts 230. In this way, the notch 231 can avoid the protruding structure corresponding to the position on the wire-retracting and releasing mechanism 100, and at the same time, the protruding structure can be engaged with the notch 231, so that it also forms a limiting effect in the width direction of the seat body 200.

[0076] In the above Figure 2 In the embodiment of the fastening device 10, the third direction z (refer to Fig.29 ), the third direction z is the thickness direction of the belt body 22, that is, the thickness direction (height direction) of the base body 200, the side of the base 102 facing the base body 200 includes a first surface 1021 and a second surface 1022, the first surface 1021 is lower than the second surface 1022, the second surface 1022 is arranged opposite to the base body 200, and the first surface 1021 and the side of the base body 200 away from the base 102 are in the same plane. Such an arrangement makes the side facing the article 20 on the same plane after the base body 200 is connected to the base 102, and no uneven structure is generated, thereby improving the comfort of the user. Of course, in other similar embodiments, the above-mentioned structure of the first surface 1021 and the second surface 1022 can also be set.

The provision of the receiving groove 240 facilitates positioning when the base 102 and the base body 200 cooperate. Exemplarily, a notch 2401 is formed in the portion of the mounting groove 210 where the second magnetic member 201 is installed, so that a portion of the position where the first magnetic member 101 is installed on the base 102 is convenient for positioning with the notch 2401.

[0078] like Fig.17As shown, in one embodiment, the seat body 200 is provided with a third clamping portion 250, and the base 102 is provided with a fourth clamping portion 104 clamped with the third clamping portion 250.
