One end of cylinder offers guide groove, is connected in the guide groove by spring and holds out against end, the outer wall of the cylinder
On be provided with external connection screw, be respectively connected with a locking nut on the external connection screw of the cylinder in outside in the U-shaped frame, it is described
Cylinder pass through inside and outside locking nut be fixedly connected with U-shaped frame, be also connected with storage on the bottom plate of the U-shaped frame
, V-groove is offered at the top of the Storage tray, the Storage tray is connected on bottom plate by height adjustment mechanism.
Further, the right end of the cylinder offers threaded hole, the threaded hole is connected with guide groove, described
Limit screw is connected in threaded hole, one end of the Limit screw passes through threaded hole and stretches in guide groove, the top
Position on tight end relative to Limit screw offers through slot.
Further: the height adjustment mechanism include be separately positioned on the first attachment base at left and right sides of Storage tray and
Second attachment base adjusts bolt, adjusting nut, guide rod and guide sleeve, and the adjusting nut is movably connected in storage vertically
On the bottom plate in seat left side, the guide rod is vertically arranged on the bottom plate on the right side of Storage tray, and first attachment base passes through
Adjusting nut, which is connected to, to be adjusted on bolt, and second attachment base is connected on the guide bar by guide sleeve.
After adopting the above structure, the utility model is provided with spring in guide groove, and the work of buffering is played by spring
With, prevent that workpiece surface is caused to damage during clamping, play the role of improve the practicality can；And the design
Also have the advantages that structure is simple, easily fabricated and practical and efficient.
