The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

The present embodiment provides a snapping mechanism. As shown in fig. 1 and 2, the clamping mechanism includes a base 1, a cover plate 2, a first clamping member 3, a second clamping member 4, and a transmission member 7. The base 1 is provided with guide post 11, and apron 2 has guiding hole 21, and apron 2 rotates and sets up in base 1, and 2 lock of apron are in the time of base 1, and guide post 11 inserts guiding hole 21. First joint spare 3 and second joint spare 4 rotate respectively and set up in base 1, and first joint spare 3 and second joint spare 4 joint apron 2 respectively. The transmission member 7 is respectively connected with the first clamping member 3 and the second clamping member 4 in a transmission manner so as to enable the first clamping member 3 and the second clamping member 4 to synchronously rotate.

This clamping mechanism utilizes first joint spare 3 and second joint spare 4 joint apron 2 simultaneously, so can lock simultaneously and be fixed in base 1 to apron 2 both sides, does benefit to the tool to the fixed of product, prevents that the unilateral that single joint spare caused from rocking or the packing force is unbalanced, can effectively improve the precision of tool. When fixed end need open apron 2, operating personnel rotates through first joint spare 3 of driving medium 7 drive and second joint spare 4 and opens apron 2, can take out product, convenient operation.

Because the appearance of the product needs to be matched with the cover plate 2 and the surface of the base 1 contacting the product, when the appearance of the product is more complex, if the cover plate 2 and the base 1 deviate, the distance between the cover plate 2 and the base 1 at the partial position of the product is smaller than the thickness of the product, and the product is crushed. In this clamping mechanism, operating personnel rotates 2 locks of apron at base 1's in-process, and guiding hole 21 can be inserted to guide post 11 on the base 1 for apron 2 leads to apron 2 before fixed with the product with base 1, until apron 2 is fixed by first joint spare 3 and second joint spare 4 joint. The guide posts 11 and the guide holes 21 can effectively prevent the relative position of the cover plate 2 and the base 1 from deviating, and protect products from being crushed.

Optionally, the cover plate 2 includes a first pressing surface, the base 1 includes a second pressing surface, the shapes of the first pressing surface and the second pressing surface are matched, and when the cover plate 2 is buckled on the base 1, the distance between the first pressing surface and the second pressing surface is equal everywhere.

In electronic products such as cell-phones and computer, the part product that needs to be fixed is uniform thickness usually, so in order to improve this clamping mechanism's application scope, the interval between the first face of compressing tightly of apron 2 and the second of base 1 compresses tightly the face equals, can evenly compress tightly the product that needs to fix.

Preferably, the cover plate 2 is provided with a holding-down block 22, and the holding-down block 22 is slidably provided on the cover plate 2 and can protrude out of the cover plate 2, as shown in fig. 3 and 4.

Through changing the distance that compact heap 22 salient apron 2, can compress tightly the product of different thickness on base 1, and can not lead to because of the thickness variation unable compressing tightly owing to changed the type of product, the phenomenon that the product removed between first compact surface and second compact surface appears, has improved stability.

The cover plate 2 further comprises a third elastic member 25 and a sliding groove 26, the pressing block 22 is slidably disposed on the sliding groove 26, and the third elastic member 25 can drive the pressing member to extend out of the first pressing surface. When the pressing piece is used for pressing a product, the situation that the pressing force is too large due to the fact that the product is too thick or too small due to the fact that the product is too thin is easy to occur. And the third elastic part 25 is driven to compress the pressing part after the pressing part is abutted against the product, so that enough pressing force can be ensured, and the pressing part can be prevented from colliding with the product rigidly to crush the product. Wherein the third elastic member 25 is a spring.

Preferably, the slide groove 26 is provided with a stopper portion 261, the holding-down block 22 is provided with an abutting portion 221, and the third elastic member 25 drives the holding-down block 22 to slide until the abutting portion 221 abuts against the stopper portion 261. The stopper 261 can restrict the stroke of the pressing block 22, and when the cover plate 2 is not closed on the base 1, the stopper 261 can prevent the pressing block 22 from escaping from the chute 26.

For further protection product, the first face that compresses tightly, the second face that compresses tightly and the face that compresses tightly piece 22 and product contact all are provided with the blotter.
