Usually, the camera is hung on the neck through a strap, and the neck is subjected to force. If the camera is hung on the neck for a long time, the neck will be very tired, and even bend and deform over time.

By installing the movable limiting mechanism 3 in the through hole 15 , the movable limiting mechanism 3 can be compressed in the groove-shaped first shell 1 , thereby achieving adjustment of the distance between the movable limiting mechanism 3 and the second shell 2 .

[0030] The connection mechanism 8 may be a wearable connection mechanism for fixing a wearable device.

[0031] The clamping object can be a backpack shoulder strap or any position where the wearable device is worn. It is not limited to being used to clamp backpack shoulder straps, but can also be used to clamp a hat, a belt, an arm sleeve, a leg sleeve, or a pocket on the surface of clothing, etc., which are convenient for clamping.

[0033] Furthermore, the connection mechanism 8 includes a rotation mechanism 5 rotatably disposed on the second shell 2 and a fixing mechanism 6 fixed on the rotation mechanism 5 .

[0034] Specifically, the rotating mechanism 5 is rotatably arranged on the second shell 2, and the fixing mechanism 6 is fixed on the side of the rotating mechanism 5 away from the second shell 2. By pressing one end of the clamping structure 4, the hinged position of the clamping structure 4 and the second shell 2 is rotated, the clamping structure 4 and the first shell 1 are loosened, so that the first shell 1 and one end of the second shell 2 are opened, the second shell 2 and the movable limiting mechanism 3 are aligned with the backpack shoulder strap, and then the second shell 2 is pressed to the first shell 1 to fix the clamping structure 4 and the first shell 1, so that the movable limiting mechanism 3 and the second shell 2 clamp the backpack shoulder strap to achieve clamping and fixing.

[0038] In this embodiment, the movable limiting mechanism 3 includes an airbag scaling mechanism or a compression rebound mechanism. The airbag scaling mechanism includes an airbag and an airbag scaling driver, the airbag scaling driver is connected to the airbag, and the airbag scaling driver is used to control the scaling space of the airbag.

[0039] In this embodiment, the compression and rebound mechanism includes a silicone compression and rebound mechanism or a sponge compression and rebound mechanism.

[0040] In this embodiment, a detachable elastic gasket is provided on the side of the movable limiting mechanism 3 that contacts the clamped object.

[0041] In this embodiment, the first shell 1 includes a first shell body 11 in the shape of a groove, a plurality of first limiting columns 12 formed in the first shell body 11, a cover plate 13 fixed to the first shell body 11, and a clamping rod 14; the second shell 2 is hinged to one end of the first shell body 11, the clamping rod 14 is fixed to the other end of the first shell body 11, and a through hole 15 is penetrated on the cover plate 13; the movable limiting mechanism 3 is arranged in the through hole 15 and fixedly connected to the plurality of first limiting columns 12, the peripheral side of the movable limiting mechanism 3 contacts the side of the cover plate 13 close to the first shell 1, and the clamping structure 4 is clamped to the clamping rod 14 to achieve fixation. By installing the movable limiting mechanism 3 in the through hole 15, the movable limiting mechanism 3 can be compressed in the first shell body 11 in the shape of a groove, so as to achieve the adjustment of the spacing between the movable limiting mechanism 3 and the second shell 2. The thickness of backpack shoulder straps is different. The movable limiting mechanism 3 is squeezed in the first shell 1, so that the second shell 2 and the movable limiting mechanism 3 can be clamped and fixed to backpack shoulder straps of different thicknesses, which has a wider range of adaptability.

[0042] In this embodiment, the movable limiting mechanism 3 is an elastic mechanism, and the elastic mechanism is limitedly arranged on the first shell. The side of the second shell close to the first shell contacts the elastic mechanism so that the elastic mechanism moves relative to the first shell, thereby changing the distance between the elastic mechanism and the first shell to adjust the clamping space of the clamping device with adaptive wearable thickness when clamping an object.

[0043] The movable limiting mechanism 3, that is, the elastic mechanism includes an elastic member 31, a clamping plate 32, a side wall 33 formed by extending the clamping plate 32 toward the side close to the first shell 1, and a limiting plate 34 formed by bending and extending the side wall 33, and the limiting plate 34 is arranged parallel to the clamping plate 32; the side of the clamping plate 32 close to the first shell 1 is fixedly connected to the other end of the elastic member 31, the side wall 33 contacts the through hole 15, and the limiting plate 34 contacts the side of the cover plate 13 close to the first shell 1 to achieve elastic limiting.

[0044] Specifically, the clamping plate 32 is passed through the through hole 15 from the side close to the first shell 1 to the side of the second shell 2 so that the side wall 33 contacts the inner wall of the through hole 15, and the two ends of the elastic member 31 are respectively fixed to the first shell body 11 and the clamping plate 32. The cover plate 13 is covered on the first shell body 11 so that the cover plate 13 presses the limit plate 34, so that the clamping plate 32 always presses the elastic member 31 to prevent the elastic member 31 from bouncing off the clamping plate 32. The limit plate 34 is arranged in parallel with the clamping plate 32, and the second shell 2 is correspondingly parallel to the first shell 1, so that the clamping plate 32 can be arranged in parallel with the first shell 1. Under the action of the elastic member 31, the clamping plate 32 is easy to adjust the distance between the second shell 2 and the clamping plate 32 to adapt to backpack shoulder straps of different thicknesses.

[0045] In this embodiment, the elastic member 31 is a spring, silica gel or sponge. The elastic member is a spring, which has good elastic effect and is convenient for saving costs. Optionally, the elastic member 31 can also be a spring sheet.

[0046] In this embodiment, the clamping plate 32 is further provided with a plurality of second limiting posts 35 on one side close to the first shell 1, and the plurality of second limiting posts 35 are provided corresponding to the plurality of first limiting posts 12, one end of the spring is sleeved on the first limiting post 12, and the other end of the spring is sleeved on the second limiting post 35. This facilitates the limiting fixation of the spring and prevents the spring from bending when compressed and the spring from detaching.

[0047] Optionally, there are six first limiting columns 12, second limiting columns 35 and springs, four of which are respectively fixed at the four corners of the clamping plate 32, and two are arranged in the middle position of the clamping plate 32, so that the clamping plate 32 is evenly stressed and has good stability.

[0048] In this embodiment, the movable limiting mechanism 3 further includes an anti-skid structure 36, which is formed on the side of the first shell 1 that contacts the clamped object, so that the anti-skid structure 36 is arranged corresponding to the second shell 2. In this way, the anti-skid effect of clamping the backpack shoulder strap between the second shell 2 and the movable limiting mechanism 3 is good, and the fixing effect is better.

[0049] In this embodiment, the anti-skid structure 36 is a plurality of evenly arranged spherical members or strip plates distributed in an array. Preferably, the anti-skid structure 36 is a spherical member.

[0050] Furthermore, the anti-skid structure 36 is made of silicone material, which is soft and has good anti-skid effect.

[0051] In this embodiment, the second shell 2 includes a second shell body 21, a limiting groove 22 provided in the second shell body 21, a through groove 23 penetrating the limiting groove 22, and a mounting groove 24 formed by a depression on one side of the second shell body 21; the rotating mechanism 5 passes through the through groove 23 and contacts the limiting groove 22, and the clamping structure 4 is provided in the mounting groove 24. The limiting groove 22 is convenient for installing the rotating mechanism 5, and the mounting groove 24 is convenient for installing the clamping structure 4, so that the mounting components on the second shell 2 are small as a whole and do not occupy assembly space.

[0052] In this embodiment, the rotating mechanism 5 includes a rotating ball 52 spaced apart in the limiting groove 22, a turntable base 51, a connecting portion 53 extending from the turntable base 51 to the side close to the first shell 1, a sliding portion 54 formed on the side of the turntable base 51 close to the first shell 1, and a rotating block 55; the sliding portion 54 is annular, the sliding portion 54 is in contact with the rotating ball 52, and the rotating block 55 passes through the through groove 23 and is fixedly connected to the connecting portion 53.

[0053] Specifically, by setting the turntable base 51 in the limiting groove 22, a sliding connection is formed between the sliding portion 54 on the turntable base 51 and the rotating ball 52, and the rotating block 55 and the connecting portion 53 are fixed to form a rotating connection between the rotating mechanism 5 and the second shell 2. When the turntable base 51 is rotated to an appropriate position, it is locked to achieve optimal position shooting, with good effect.

[0054] In this embodiment, the fixing mechanism 6 includes a hole buckle 61 fixed to the rotating mechanism 5 and a fixing member 62 fixed in the hole buckle 61. By fixing the camera device on the fixing member 62, the hole buckle 61 is rotated to rotate the rotating mechanism 5 together, and the corresponding angle is adjusted, so that shooting at different shooting angles can be achieved, and the functions are diverse.

[0055] In this embodiment, the fixing member 62 is a silicone plug.

[0056] The working principle of the utility model is as follows:

[0057] By releasing the clamping structure 4 from the clamping rod 14, one end of the second shell 2 is separated from the first shell 1, and the opening function is realized. The first shell 1 and the second shell 2 are passed through the backpack shoulder strap, so that the backpack shoulder strap is set between the movable limiting mechanism 3 and the second shell 2. By pressing the second shell 2 toward the first shell 1, the backpack shoulder strap is clamped by both the second shell 2 and the movable limiting mechanism 3. When the clamping structure 4 is hung on the clamping rod 14 again, the second shell 2 and the first shell 1 are fixed, so that the clamping device and the backpack shoulder strap are well fixed. Since the movable limiting mechanism 3 can be compressed into the first shell 1 under pressure, it is convenient to adjust the distance between the second shell 2 and the movable limiting mechanism 3 to adapt to the clamping of backpack shoulder straps of various thicknesses. The camera device is installed and fixed on the fixing mechanism 6, and the fixing mechanism 6 is rotated to rotate the rotating mechanism 5 on the second shell 2 to an appropriate shooting angle, and then locked, so that the shooting effect of the camera device is better.
