The purpose of the utility model and the technical problem thereof can be further realized by adopting the following technical measures.

Alternatively, the mechanical fixing device described above, wherein the second barrier has 2 pieces.

Alternatively, the mechanical fixing device may be arranged such that the hole is provided in the center of the third shutter.

Borrow by above-mentioned technical scheme, the utility model discloses at least, have following advantage: the fixing device is composed of a plurality of telescopic supporting columns, and can be independently telescopic along with the shape of the mechanical part, so that the contact area between the fixing device and the mechanical part is increased during clamping, and a proper clamping force is ensured without damaging an object.

The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.

Fig. 1 is a mechanical fastening device according to an embodiment of the present invention;

FIG. 2 is a transverse use view of the mechanical fastening device;

FIG. 3 is a side sectional view of the fixture;

fig. 4 is a top view of the fixture.

Detailed Description

The utility model discloses a solve the easy problem of damaging of single-point atress among the prior art mechanical parts clamping process, provide a mechanical fixing device to at increase area of contact, the centre gripping is and not damage mechanical parts.

The utility model discloses technical scheme for solving above-mentioned technical problem, the general thinking is as follows:

the utility model provides a pair of mechanical fixing device.

To further illustrate the technical means and effects of the present invention adopted to achieve the objects of the present invention, the following detailed description of the embodiments, structures, features and effects of the mechanical fastening device according to the present invention will be made with reference to the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, with the specific understanding that: both a and B may be included, a may exist alone, or B may exist alone, and any of the three cases can be provided.

As shown in fig. 1, an embodiment of the present invention provides a mechanical fixing device, which includes: a baffle, a rotating structure and a fixed structure 5. The baffle plates comprise a first baffle plate 1, a second baffle plate 2 and a third baffle plate 3, a hole 3.1 is formed in the third baffle plate 3, and the hole 3.1 is provided with internal threads; when the device is used vertically, the second baffle 2 has 2 blocks; as shown in fig. 2, the second barrier 2 has only 1 block as a base when used in a lateral direction. The rotating structure comprises a handle 6 and a threaded rod 4 with external thread, the threaded rod 4 is matched with the hole 3.1, and the hole 3.1 is preferably arranged at the center of the third baffle 3.
