For example, the return spring may be a torsion spring, the spiral structure in the middle of the torsion spring is an elastic portion, and the two ends of the spiral structure respectively extend out to form a first support arm and a second support arm. Normally, under the effect of torsional spring, the first end of first splint 2 and the first end of second splint 3 support tightly, when like the second end of first splint 2 and the second end of second splint 3 exert external force simultaneously, first splint 2 and second splint 3 transmit the force respectively for the both ends of torsional spring, at this moment, the first end of first splint 2 and the first end of second splint 3 break away from the contact, the helicitic texture of torsional spring takes place deformation and stores energy, after external force disappears, the helicitic texture of torsional spring resumes the original form and releases the energy of storing for the first end of first splint 2 and the first end of second splint 3 resume the butt state again.
In use, a user presses the second end of the first clamping plate 2 and the second end of the second clamping plate 3 with fingers such that the first end of the first clamping plate 2 and the first end of the second clamping plate 3 are out of contact, then a corner of the user's clothing is placed between the first end of the first clamping plate 2 and the first end of the second clamping plate 3, then the user releases the second end of the first clamping plate 2 and the second end of the second clamping plate 3, and after the first end of the first clamping plate 2 and the first end of the second clamping plate 3 are restored to the abutting state, the corner of the user's clothing is clamped, thereby wearing the inertial measurement unit on the user.
In one embodiment of the utility model, the two rotational coupling structures share a common rotational axis, and the rotational axis passes through the helical structure. Specifically, the first clamping plate 2 and the second clamping plate 3 are rotationally connected through a rotating shaft, and the rotating shaft is respectively arranged in the two first rotating holes and the two second rotating holes in a penetrating manner, so that the rotating shaft, the two first connecting plates 22 and the two second connecting plates 31 form two rotating connection structures.

The above embodiment using a torsion spring as a return spring should not be construed as limiting the utility model, but in fact any form of spring, which is capable of achieving the same effect as a torsion spring, may be regarded as an equivalent alternative to the above embodiment. For example, the return spring may be a V-shaped spring, the V-shaped spring is disposed between the first clamping plate 2 and the second clamping plate 3, two ends of the V-shaped spring are respectively abutted against the first clamping plate 2 and the second clamping plate 3, after the second ends of the first clamping plate 2 and the second clamping plate 3 are subjected to an external force, the bending portion of the V-shaped spring is deformed, at this time, the first ends of the first clamping plate 2 and the second clamping plate 3 are separated from contact, and after the external force disappears, the V-shaped spring is deformed in a recovery manner, so that the first ends of the first clamping plate 2 and the second clamping plate 3 are in a re-abutting state.
Referring to fig. 1 and 2, in one embodiment of the present utility model, a first end of the first clamping plate 2 is provided with a first clamping tooth 23, the first clamping tooth 23 is located on the second surface 21, a first end of the second clamping plate 3 is provided with a second clamping tooth 32 corresponding to the first clamping tooth 23, and the second clamping tooth 32 is located on the third surface 30. When the clothes clamping device is used, after the first end of the first clamping plate 2 and the first end of the second clamping plate 3 are abutted tightly, the first clamping teeth 23 and the second clamping teeth 32 are in contact, when a user places one corner of clothes between the first clamping plate 2 and the second clamping plate 3, the first clamping teeth 23 and the second clamping teeth 32 are matched, so that the clamping force of the first clamping plate 2 and the second clamping plate 3 on the clothes is increased, and the wearing reliability is improved.
It should be noted that, if the first clamping tooth 23 and the second clamping tooth 32 are respectively provided with one or not provided with the first clamping tooth 23 and the second clamping tooth 32, after the first clamping plate 2 and the second clamping plate 3 clamp the clothes, the first clamping plate 2 and the second clamping plate 3 are in line contact with the clothes, and the contact area between the first clamping plate 2 and the second clamping plate 3 and the clothes is smaller, so that the reliability of the first clamping plate 2 and the second clamping plate 3 after clamping the clothes is not high, and the first clamping plate 2 and the second clamping plate 3 are relatively easy to deviate or even fall off.
Thus, in one embodiment of the present utility model, the first clamping plate 2 is provided with a plurality of first clamping teeth 23, the plurality of first clamping teeth 23 are distributed along the length direction of the first clamping plate 2, and each first clamping tooth 23 extends along the width direction of the first clamping plate 2; similarly, the second clamping plate 3 is provided with a plurality of second clamping teeth 32 corresponding to the first clamping teeth 23, the plurality of second clamping teeth 32 are distributed along the length direction of the second clamping plate 3, and each second clamping tooth 32 extends along the width direction of the second clamping plate 3. It should be noted that, after the first end of the first clamping plate 2 and the first end of the second clamping plate 3 abut, each first clamping tooth 23 abuts against the corresponding second clamping tooth 32, that is, when the user places a corner of the clothing between the first clamping plate 2 and the second clamping plate 3, the first clamping teeth 23 and the second clamping teeth 32 can act on the clothing, so as to clamp the clothing. Since each of the first and second clamping teeth 23 and 32 has an acting force on the laundry when the first and second clamping plates 2 and 3 clamp the laundry, the contact area between the first and second clamping plates 2 and 3 and the laundry is large, and thus, when the first and second clamping plates 2 and 3 clamp the laundry, the reliability is also higher, so that the inertial measurement unit 1 is not easily deviated and dropped.
Referring to fig. 4, in one embodiment of the present utility model, the second end of the first clamping plate 2 is provided with anti-skid patterns 25, and the anti-skid patterns 25 are located on the first surface 20. By providing the anti-slip pattern 25, an increased friction force of the first clamping plate 2 is enabled, and when a user applies pressure through the second end of the finger-like first clamping plate 2 and the second end of the second clamping plate 3, the finger can be prevented from slipping off the first clamping plate 2.
In one embodiment of the present utility model, the first end of the first clamping plate 2 and the first end of the second clamping plate 3 are each provided in a circular arc structure. Through setting the first end of first splint 2 and the first end of second splint 3 to circular arc structure, can prevent that sharp-pointed position from appearing in the first end of first splint 2 and the first end of second splint 3 to avoid damaging clothing or fish tail human body behind first splint 2 and the tight clothing of second splint 3 clamp.
