Specific embodiments

For the ease of those skilled in the art's understanding, will combine specific embodiment and accompanying drawing that the utility model structural principle is described in further detail below:

With reference to Fig. 1-2, a kind of clamping mechanism comprises that a left side holder cover 1, guide rail 2, right holder cover 3, covers to be provided with to hold in the palm about making to cover in Zuo Tuogai, guide rail and right holder and opens and close up so that the clamp assembly of gripping object.Described guide rail comprises left rail assembly, right guide assembly and guide cover 5; The left rail assembly is made up of left rail covers 6,7; Be provided with sliding bolt 11, the sliver 12 that is used for fixing the guide rail movement direction of being furnished with stage clip, the tooth bar A 13 that is used to realize guide rail movement on the left rail loam cake 6; Right guide assembly comprises right guide rail 4 and gear cluster 17, left side holder cover be provided with on 1 with right guide assembly in the tooth bar B 15 of gear cluster 17 gear motions; On guide cover 5, be provided with the spring A 8 that connects left rail and produce pulling force, on right guide rail, be provided with the spring B 18 that connects right guide rail and produce pulling force.

Described clamp assembly comprises that being located at right holder covers the connecting rod actuation button 9 at 3 places, is installed in connecting rod 16, gear cluster 17 and connecting rod fixed support 19 on the right guide rail 4; Gear cluster meshes with tooth bar A 14 tooth bar B 16 respectively, and connecting rod fixed support 19 is used for support link and is furnished with extension spring.The holder of a described left side covers and is provided with the link stopper 14 of being furnished with stage clip.Cover with right holder at Zuo Tuogai 1 the foam pad 10 that is used for better clamping article is housed on 3.

1, unclasping and clamping process of clamping mechanism:

Press right holder and cover the connecting rod actuation button 9 on 3; Connecting rod 16 is under leverage power at this moment, and tail end separating tooth wheels 17 are because the tooth bar on the left rail no longer receives the antagonistic force of gear cluster; Left rail slides to the right under the tension of spring A 8; The right guide rail 4 of this moment through little sliding bolt 11 and left rail 6 bolts together, right guide rail 4 slides to the right with left rail 6 simultaneously, but separates as yet;

After left rail 6 ejects certain distance, be arranged on a left side and ask the block 14 that covers on 1 under the application force of its small pressure spring, to pop up, just in time block the left side of left rail 6, its right side is blocked by Zuo Tuogai, makes left rail 6 fixed.Simultaneously, gear cluster tripping tooth bar 15 meshes together with tooth bar 13; Little sliding bolt 11 upwards slides under the squeese pressure effect of the oblique projection of Zuo Tuogai 1, no longer tacks right guide rail 4; Right guide rail 4 begins right the slip under the tension of spring B 18, until opening fully;

Because link design is a folk prescription to pinning gear cluster, to enforce right holder and cover 3, right guide rail 4 can be moved to the left, and utilizes the little tooth pitch of gear cluster rotation can accurately select the gap of opening and utilize the elastic force of foam-rubber cushion 10 just can clamp various portable objects; In the time of need taking off the article of clamping, only need click connecting rod actuation button 9, make connecting rod 16 not block gear cluster 17, under the effect of spring force, guide rail slides to the right, thereby unclamps folded object;

In the whole process that unclasps and clamp, all can cover the sliding position of the connecting rod actuation button 9 accurate positioning guide rails on 3 through controlling right holder.

2, close up process:

When needs close up clamping mechanism fully, to enforce right holder and cover 3, right guide rail 4 can slide left; Tightly connect together up to heavily being incorporated under the effect of little sliding bolt 11 with left rail 6, meanwhile, the slide inclined-plane extruding block of collision link stoppers 14 of right guide rail 4 makes its retraction; Block 14 no longer blocks left rail 6, and gear cluster tripping tooth bar 13 meshes together with tooth bar 15; Left rail 6 just continues to slide left with right guide rail 4 like this, up to closing up fully; At this moment; Because link design is a folk prescription to pinning gear cluster, under the tension of connecting rod 16 small extension spring in connecting rod fixed support 19, its tail end tightly fastens gear cluster 17; Make the gear cluster 17 can't backward rotation; The tooth bar of connection gear group is the corresponding position quiescence also, and the residing guide rail of tooth bar can outwards not move, and right holder is covered 3 and can not be flicked;

Closing up under the state, spring A 8 all locates to draw back state with spring B 18, guarantees by the lower link actuation button time, and guide rail possesses the power that slides to the right.

The above is the preferable embodiment of the utility model, under the situation that does not break away from the utility model design, carries out any obvious distortion and replacement, all belongs within the utility model protection domain.
