Described retainer front is provided with at least one support, offers axis hole on the support, and collet body bottom rear side is provided with corresponding fixed shaft hole, and described collet body and support are hinged; When retainer upper grip body was two or more, a plurality of collet bodies connected with fixed axis, and suit location axle sleeve limits spacing on the fixed axis between the adjacent collet body.

As further improvement of the utility model, the roller and collet body rear side contact point to the collet body upside of the transmission mechanism in the described upper shaft hole form a ramp; The roller and collet body rear side contact point to the collet body downside of the transmission mechanism in the lower shaft hole form a lower inclined plane.

As further improvement of the utility model, the preceding lower end of described collet body is provided with a protuberance.

As further improvement of the utility model, described collet body is a hollow structure.

The utility model compared with prior art, simple in structure, compact and reasonable, described symmetrical hold down gag respectively provides power by upper and lower two air bags, production cost is lower, and can be extended to many group collet bodies and usefulness, improves the clamping fastness.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

Referring to shown in Figure 1, described thin plate splicing fixture comprises two identical, symmetrical hold down gags of structure, described hold down gag comprises: offer at least a upper shaft hole 11 and a lower shaft hole 12 retainer 1, being inserted in described upper shaft hole 11 and the lower shaft hole 12 can axially movable transmission mechanism 2 and be installed on the retainer 1, contact at least one collet body 3 of cooperation with described transmission mechanism 2.

Transmission mechanism 2 structures in described upper shaft hole 11 and the lower shaft hole 12 are identical, comprise position-limited rack 21, bladder retaining slot 22, air bag 23, elastic plate 24, band roller shaft 25 and roller 26; Position-limited rack 21 and bladder retaining slot 22 are connected in described retainer 1 back side, corresponding with upper shaft hole 11 or lower shaft hole 12, air bag 23 and elastic plate 24 are installed in the bladder retaining slot 22 and also remain in the groove for limited 21, air bag 23 1 sides are close to bottom land, opposite side is close to elastic plate 24, elastic plate 24 and band roller shaft 25 back end in contact, the roller 26 of band roller shaft 25 front ends cooperates with collet body 3 back side contacts.

Described retainer 1 front is provided with at least one support 13, offers axis hole 14 on the support 13, and collet body bottom rear side is provided with corresponding fixed shaft hole 31, and described collet body 3 and support 13 are hinged; Referring to Fig. 2, when retainer 1 upper grip body 3 was two or more, a plurality of collet body 3 usefulness fixed axis 4 connected, and suit location axle sleeve 5 limits spacing on the fixed axis 4 between the adjacent collet body 3.

The roller 26 of the transmission mechanism 2 in the described upper shaft hole 11 forms a ramp 32 with collet body 3 rear side contact points to collet body 3 upsides; The roller 26 and the collet body 3 rear side contact points of the transmission mechanism 2 in the lower shaft hole 12 form a lower inclined plane 33 to collet body 3 downsides, and ramp 32 and lower inclined plane 33 are beneficial to the conduction of roller 26 rollings and power.
