The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The embodiment of the present invention provides a hidden structure 100 of a stud, and the hidden structure 100 of the stud can be used in the clamping device 1000, and can also be used in other suitable products. In addition, the stud 22 in the hidden structure 100 of the stud is mainly used for connecting external equipment, and can be used for connecting other parts in the product.

As shown in fig. 1 to 3, the stud hiding structure 100 includes a base 1, a mounting seat 2, a knob 3, and a cover 4. The mounting seat 2 includes a seat body 21 and a stud 22, wherein the base 1 is convexly provided with at least two guide posts 11, correspondingly, the seat body 21 is provided with the stud 22 and is provided with at least two guide holes 23 along the thickness direction of the seat body 21, the guide holes 23 are located at the periphery of the stud 22, and each guide hole 23 is inserted into the corresponding guide post 11, so as to slidably mount the mounting seat 2 on the base 1.

In the present embodiment, as shown in fig. 1 to 4, a hollow cavity 33 (see fig. 3) is opened in a middle portion of the knob 3, and the knob 3 is sleeved on the seat body 21 of the mounting seat 2. The cover body 4 is covered on the knob 3 to form an accommodating cavity 5 together with the knob 3 and the base 1; the cover body 4 is provided with an avoiding hole 41 communicated with the accommodating cavity 5.

As shown in fig. 4 and 5, when the knob 3 rotates relative to the seat body 21 of the mounting seat 2, the seat body 21 of the mounting seat 2 can move in the accommodating cavity 5 along the depth direction thereof, so that one end of the stud 22 can pass through the avoiding hole 41 and be exposed out of the cover body 4, or be hidden in the avoiding hole 41 or the accommodating cavity 5.

It is understood that the working principle of the hidden structure 100 of the stud is roughly as follows: in the hidden structure 100 of the stud, the mounting base 2 is slidably disposed on the base 1, the knob 3 is sleeved on the base body 21 of the mounting base 2, and the knob 3 can rotate relative to the base body 21, and in the process of rotating the knob 3, because at least two guide posts 11 on the base 1 are inserted into the guide holes 23 on the base body 21 of the mounting base 2, the base body 21 cannot rotate along with the knob 3, but moves along the extending direction of the guide posts 11 (specifically, the depth direction of the accommodating cavity 5 or the height direction of the base 1) under the guidance of the guide posts 11, so that the stud 22 disposed on the base body 21 of the mounting base 2 also moves along with the guide posts 11, and thus when the stud is connected with an external component or other components, the stud 22 can directly move in the direction of the cover body 4 in the accommodating cavity 5 by rotating the knob 3, and one end of the stud 22 passes through the avoiding hole 41 of the cover body 4 and is exposed out of the cover body 4;

on the contrary, when the stud 22 is not needed, the knob 3 can be rotated reversely to move the seat body 21 in the accommodating cavity 5 in a direction away from the cover body 4, so that one end of the stud 22 moves downwards to be hidden in the avoiding hole 41 or the accommodating cavity 5, thereby hiding the stud 22.

In summary, compared with the prior art, the hidden structure 100 of the stud has at least the following beneficial effects: the hidden structure 100 of the stud is that the base body 21 of the installation base 2 provided with the stud 22 and the guide hole 23 is arranged on the base 1 in a sliding manner, the knob 3 is rotatably sleeved on the base body 21, and the base 1, the knob 3 and the cover body 4 jointly enclose the accommodating cavity 5 for the movement of the base body 21, because the base 1 is provided with at least two guide posts 11, through the insertion and connection cooperation of the guide posts 11 and the guide hole 23, the sliding connection between the installation base 2 and the base body 21 is ensured, and it is also ensured that the installation base 2 does not rotate together with the rotation in the rotation process of the knob 3, but the installation base 2 moves along the guide posts 11, so that the stud 22 moves upwards relative to the cover body 4 to extend out of the cover body 4 for a distance or moves downwards to be hidden in the cover body 4, and when external equipment or other parts are required to be connected, the stud 22 moves upwards and is exposed out of the cover body 4 through the rotation of the knob 3. Generally, the hidden structure 100 of the stud is simple and reliable in structure, convenient to operate and very beneficial to storage and carrying.

In order to make the technical solution of the present invention better understood, the technical solution of the embodiment of the present invention will be clearly and completely described below with reference to fig. 1 to 7.
