And the first clamping component 10 and the second clamping component 20 respectively have a clamping surface facing each other in a moving direction thereof; the locking mechanism comprises locking teeth 31, disposed on the first clamping component 10 along a sliding direction; and a brake assembly, disposed on the second clamping component 20, comprising at least a brake component 32 movably mounted on the slide component, with a brake end 332 of the brake component 32 movable between an engaging position and an disengaging position of the locking tooth 31.

As a preferred technical scheme of the present embodiment, the brake component 32 in the locking mechanism is applied a biasing force that tends to press the brake end 332 towards the locking teeth 31, and the locking teeth 31 are one-way teeth that are engaged with the brake end 322 to allow the movement in the clamping direction and prevent the movement in the releasing direction. The brake component 32 is pivotally mounted on a sliding component related thereto, and the biasing force is provided by a torsion spring. The brake component 32 is formed with a pivoting structure that comprises a fixing base 323 fixed on the sliding component related thereto, and a pivot 324 provided on the fixing base 323, and the brake 32 is rotatably disposed relative to the fixed base 323 through the pivot 324. A biasing force mechanism for separating the champing surfaces of the first clamping component 10 and the second clamping component 20 from each other is provided between the first clamping component 10 and the second clamping component 20. The first spring base 41 is provided on the first clamping component 10; the second spring base 42 is provided on the second clamping component 20; and a biasing force spring 43 is provided between the first spring base 41 and the second spring base 42.

The first clamping component 10 comprises a first sliding component extending towards the second clamping component 20; and the second clamping component 20 comprises a second sliding component extending towards the first clamping component 10; and the first sliding component and the second sliding component are connected so as to be slidable only in an extending direction thereof. In particular, it is preferable that the first sliding component is a sliding column, the second sliding component is a sliding sleeve slidably sleeved on the sliding column; and the fixing base 323 is provided at a position where the sleeve corresponds to the locking teeth 31. The side of the locking teeth 31 that faces the clamping surface of the first clamping component 10 is arranged on the sliding column. The first spring base 41 is provided in an inner cavity of the sliding column; the second spring base 42 is provided in an inner cavity of the sliding sleeve; and the biasing spring 43 is provided in the inner cavities of the sliding column and the sliding sleeve between the first spring base 41 and the second spring base 42. The retaining clip further comprises a limiting structure for preventing the first clamping component 10 from slipping relative to the second clamping component 20. The limiting structure comprises a limiting slot 311 formed on the sliding column along an arrangement direction of the locking teeth 31; a limiting block 312 slidably engaged with the limiting slot 311 and fixedly disposed on the sliding sleeve so as to guide the sliding of the first clamping component 10. A shim plate 53 is provided on the clamping surface of the second clamping component 20. The first clamping component 10 and the second clamping component 20 are respectively provided with a soft rubber pad 43.

As an alternative embodiment, the locking teeth 31 are not limited to one-way teeth, and when the locking teeth are selected as two-way teeth or irregular teeth, it is only necessary to disengage the brake end 322 from the locking teeth 31 when only the relative position of the first clamping component 10 and the second clamping component 20 is to be adjusted; in other words, the arrangement of one-way teeth makes the adjustment process easier.

As an alternative embodiment, the locking teeth 31 are provided on the spool of both sides of the clamping surfaces of the first clamping component 10, and the braking assemblies are provided into two groups and are respectively provided corresponding to both sides of the locking teeth 31. And the height of the two sets of brake assemblies may be the same or different to accommodate the operation.

As an alternative embodiment, as shown in FIG. 1 and FIG. 2, the locking teeth 31 are provided on the first clamping component 10, but the locking teeth 31 may be provided on the second clamping component 20, in this case, it is only necessary to provide the locking mechanism on the first clamping component 10, although this arrangement is not shown in the drawings, however, those skilled in the art may achieve it in view of the above description.

In the above embodiment, since the brake end 322 of the brake component 32 may be driven to move between an engaging position and an disengaging position of the locking tooth 31, thus when the first clamping component 10 and the second clamping component 20 need to be locked, the user just needs to move the brake end 322 to an engaging position, where the first clamping component 10 and the second clamping component 20 cannot move relative to each other; when the relative position of the first clamping component 10 and the second clamping component 20 needs to be adjusted, the user just needs to move the brake end 322 to an disengaging position where the first clamping component 10 and the second clamping component 20 may move relative to each other without being locked by the locking mechanism. Therefore, in the present embodiment, the braking component 32 is directly used to brake the locking teeth 31, which is easier than the brake modes of using the push-button, gears and the rack transmission in the prior art, thereby contributing to the reduction of the production cost, and to reduce the size of the clips.

In the above embodiment, the locking teeth 31 are provided in two ways, the first being arranged as the side of the locking teeth 31 facing the clamping surface of the first clamping component 10, the other being provided on both sides of the clamping surfaces, that is to say, the clamping surfaces of the first clamping component 10, which are specifically shown in FIG. 2 and FIG. 3, respectively. Further, a shim plate 53 is provided on the clamping surface of the second clamping component 20 to adjust the position of the apparatus on the clamping surface.

In the present embodiment, it is preferable that the brake component 32 is a bent plate structure having a brake end 322 and a pressing end 321, and it is further preferable that the bending angle of the bent plate is such that the brake end 322 and the one-way teeth are in contact with each other, the pressing end 321 is in a vertical state, thereby facilitating the pressing operation.

In the present embodiment, as shown in FIG. 4, the brake assembly further comprises a fixing base 323 formed on the second clamping component 20, and a pivot 324 provided on the fixing base 323. Specifically, the fixing base 323 may be two mounting plates with coaxial mounting holes, and the pivot 324 is fixedly provided in the mounting holes and is rotatably connected to the brake component 32, and a pivot side cover for closing the mounting hole is provided at both ends of the pivot 324. Alternatively, the pivot 324 is rotatably provided in the mounting holes and fixedly connected to the brake component 32, which plays the same role of making the brake component 32 being rotatably disposed relative to the one-way teeth 31.

In the present embodiment, a limiting structure is also provided for providing a guide to the relative sliding between the first champing component 10 and the second champing component 20, which makes the structure more stable. The limiting structure comprises a fixed limiting block 312 and a limiting slot 311 formed on the first clamping component 10 and cooperating with the limiting block 312, thus when the first clamping component 10 is moved relative to the second clamping component 20, the limiting slot 311 is also moved relative to the limiting block 312, in one embodiment, the width of the limiting slot 311 is slightly larger than that of the limiting block 312, thereby playing the role of guiding and a limiting. As shown in FIG. 2 and FIG. 3, the limiting slot 311 and the limiting block 312 may be provided at the intermediate position and the one-way teeth 31 are divided into two sections, but it needs to be noted that the limiting slot 311 and the limiting block 312 may be provided on one side of the one-way teeth 31, and it is only necessary that the lengthwise direction of the limiting slot 311 and the direction of movement of the first champing component 10 are uniform. As may be seen from the above, the limiting structure of the present embodiment includes only the limiting slot 311 and the limiting block 312, and the structure is relatively simple; and the limiting slot 311 and the limiting block 312 are located outside the retaining clip thus to achieve the role of providing limitation and orientation in the situation that the difficulty of processing conditions does not become higher.

In the present embodiment, in order to firmly champ devices such as a mobile phone or the like, the first clamping component 10 and the second clamping component 20 are respectively provided with a gap compensating component, the relative distance between the two clamping surfaces in this embodiment is adjusted by the one-way teeth 31 and the minimum adjustment accuracy of the one-way teeth 31 is the teeth pitch, which makes it possible for the clamped component to be in a state where it cannot be clamped, therefore, the above gap compensating component is designed to adjust the relative distance. As a preferred the gap compensating component, after resiliently deformed, the self-restoring force of the soft pad 43 is able to continue to clamp the device.

In the present embodiment, the first clamping component 10 and the second clamping component 20 have a damping structure provided therebetween, in particular, under the action of the biasing force spring 43, if the damping structure is not provided, the first champing component 10 will quickly bounce when the brake assembly is unlocked, which is unfavorable to the positioning operation. Therefore, it is necessary to provide a damping structure between the first champing component 10 and the second champing component 20, as an preferred design, the damping structure may be a structure such as a damping oil provided between the sliding column and the sliding sleeve; as a substitution, the damping structure may also be a resilient interlayer and other structures capable of providing damping, which is not repeated one by one herein.

Referring to FIG. 8, when the lock is released, the pressing end 321 of the brake component 32 is pressed, and the brake end 322 of the brake component 32 is tilted away from the locking teeth 31, and the first champing component 10 will move upward by the biasing force mechanism to release the clamping effect on the phone.

Then referring to FIGS. 12-16, in the same manner as described above, when the mobile phone needs to be unlocked, the brake component 32 on both sides are pressed so that the brake end 322 of the brake component 32 is tilted away from the lock teeth 31, and the first champing component 10 will move upward by the biasing force mechanism to release the clamping effect on the phone.

In the present embodiment, referring to FIG. 1, the biasing force mechanism further comprises a supporting rod 411 for supporting the biasing force spring provided on the first spring base 41, and, in one embodiment, the length of the supporting rod 411 is such that the supporting rod 411 abuts against the second spring base 42 of the second champing component 20 when the first clamping component 10 is moved downwardly to the limit position.

In the present embodiment, referring to FIG. 2, when the brake assembly is provided on the back of the clamping surface, the Bluetooth handle slot 52 is, in one embodiment, provided vertically below the brake assembly; when the brake assembly is provided on both sides of the clamping surface, the Bluetooth handle slot 52 is, in one embodiment, provided horizontally on the back of the clamping surface.
