In the present embodiment, the telescopic structure 400 includes an anti-loose lock mechanism 500, and the anti-loose lock mechanism 500 is used to prevent the wrist strap 200 from being released by the inertia force.

Specifically, the anti-loose lock mechanism 500 includes a ratchet 510, a pawl 520, and a second elastic member 530. The ratchet wheel 510 is fixed in the housing 110, the ratchet wheel 510 is preferably a ring-shaped ratchet wheel 510 surrounding the winding wheel 440, and the inner ring of the ratchet wheel 510 is provided with a tooth space. The ratchet 510 has a notch 511 to form a guide. The pawl 520 is rotatably disposed on the winding wheel 440, the second elastic member 530 is connected to the pawl 520 for keeping the pawl 520 disengaged from the ratchet wheel 510, and the pawl 520 can be engaged with the ratchet wheel 510 under the action of centrifugal force to limit the rotation of the winding wheel 440. In this embodiment, the second elastic member 530 is preferably a tension spring, and the upper surface of the winding wheel 440 is provided with an eccentric shaft for seating the ratchet 510 and a stud for fixing the tension spring. The ratchet wheel 510 is installed on the eccentric shaft and is guaranteed to rotate flexibly, one end of a tension spring is hung on the protruding column of the winding wheel 440, and the other end of the tension spring hooks the upper end of the ratchet wheel 510 and guarantees a certain tensile elasticity.

Under normal state, the ratchet 510 and the pawl 520 keep a certain gap and are in a disengaged state, so as to ensure that the winding wheel 440 can normally rotate, thereby realizing the extension and contraction of the wrist strap 200.

When a wearer swings at a high speed, the wrist strap 200 is linked with the rope 420 to be separated in an accelerating way, at the moment, the pawl 520 swings outwards under the action of centrifugal force to be meshed with the ratchet wheel 510, the wrist strap 200 is clamped instantly, and therefore the anti-loosening effect of the wrist strap 200 is achieved; when the swing motion is finished, the centrifugal force disappears, and the pawl 520 returns to the original position to be separated from the ratchet wheel 510 under the tension of the tension spring. The user only needs to pull the wrist strap 200 slowly when removing and wearing the wrist strap 200, and the centrifugal force of the pawl 520 is not enough to overcome the pretension force of the tension spring, so that the pawl 520 is not engaged.

The anti-loose locking mechanism 500 of the wrist-worn device can realize normal wearing of wrist bands 200 such as watches and bracelets during strenuous exercise; the wrist strap 200 can be automatically locked, and the anti-loosening effect can be realized without the operation of a wearer; the anti-loosening device is purely passive, simple in structure and low in cost.

In this embodiment, an extension portion 120 extending along the length direction of the main body 100 is disposed at one end of the main body 100 connected to the wrist strap 200 through the telescopic structure 400, a slot is formed on the extension portion 120, and the wrist strap 200 can be inserted into the slot and fixedly connected to the rope 420. The stretching of the string 420 can be hidden in the slot during the stretching of the wrist band 200, and can also guide the movement of the wrist band 200.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
