The relation of "connected" between the components shown in the drawings and described in the specification can be understood as fixedly connected or detachably connected or integrally connected; the connecting elements can be directly connected or connected through an intermediate medium, and persons skilled in the art can understand the connecting relation according to specific conditions, and can use the connecting elements in a screwed connection or riveting connection or welding connection or clamping connection or embedding connection mode to replace different embodiments in a proper mode.

The terms of orientation such as up, down, left, right, top, bottom, and the like in the description and the orientation shown in the drawings, may be used for direct contact or contact with each other through another feature therebetween; above may be directly above and obliquely above, or it simply means above the other; other orientations may be understood by analogy.

The technical scheme and the beneficial effects of the invention are clearer and clearer by further describing the specific embodiment of the invention with the accompanying drawings of the specification; and are intended to be illustrative of the invention and not to be construed as limiting the invention.

First embodiment:

referring to fig. 1-3, there is preferably provided an automatic clamp for an embodiment of the present invention, which includes a first rotating arm 2 and a second rotating arm 3, and a propelling mechanism including a first clamping portion 4 and a second clamping portion 5, which are slidably disposed on a guide shaft 7.

The guide shaft 7 is sleeved with a return spring 6, the first clamping part 4 and the second clamping part 5 form an energy storage state when being relatively close to each other by means of the return spring 6, and the first clamping part 4 and the second clamping part 5 form a relative far-away direction action to elastically reset when being relieved of stress. The first clamp 4 and the second clamp 5 have passage holes that are fitted around the guide shaft, by means of which the first clamp and the second clamp are moved in parallel on the guide shaft 7. The number of the return springs 6 is multiple, and the return springs are spiral springs. Can be sleeved on the guide shaft 7 in sections.

A return spring 6 is arranged between the first rotating arm 2 and the second rotating arm 3; when the object supporting part 1 is empty, the first clamping part 4 and the second clamping part 5 are opened and reset relatively under the elastic force of the reset spring 6.

The first clamp 4 and the second clamp 5 use a guide shaft 7 as a stroke guide. The first clamp part 4 and the second clamp part 5 are in sliding fit with the guide shaft 7. The object supporting part 1 is provided with a groove part 8 for accommodating the bottom of the mobile phone; the object supporting part 1 is provided with a limiting hook 9 which is folded upwards. The first rotating arm 2 and the second rotating arm 3 are hinged with each other, and simultaneously, the first rotating arm and the second rotating arm are hinged with the object supporting part 1. The above-described urging mechanism can be applied to this embodiment or other embodiments.

Second embodiment:

as shown with reference to fig. 4, it is substantially the same in structure as the first embodiment, except that: the first rotating arm 2 and the second rotating arm 3 can be hinged on different positions of the object supporting part 1 in a separable mode, and therefore stress is balanced.

Third embodiment:

as shown with reference to fig. 5, it is substantially the same in structure as the first embodiment, except that: the first rotating arm 2 and the second rotating arm 3 can be hinged on different positions of the object supporting part 1 in a separable mode, and therefore stress is balanced. The object supporting part 1 is provided with a placement space avoiding part, so that the universality of different models of mobile phones is improved.

The operation and principles will be further described in conjunction with the above description, taken in conjunction with all of the accompanying drawings:

when the mobile phone holder is used, the object supporting part 1 is forced by the gravity of an object to force the first rotating arm 2 and the second rotating arm 3 to pull the first clamping part 4 and the second clamping part 5 to clamp the mobile phone, and when the mobile phone is taken out, the reset spring 6 enables the first clamping part and the second clamping part to reset to the initial state. The utility model discloses simple structure, action are steady, the structure equipment is convenient, the operation is very convenient, use extensively, can also automatic centre gripping and automatic re-setting's characteristics.

While the invention has been described in terms of the preferred embodiments described above, there may be alterations, permutations, and equivalents, which fall within the scope of this invention; there may be many alternative ways of implementing the invention. It is therefore intended that the following appended claims be interpreted as including all such alterations, permutations, and equivalents as fall within the true spirit and scope of the present invention; it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and modifications and substitutions based on the known art are intended to fall within the scope of the present invention, which is defined by the claims.
