Be provided with along screw rod through hole radially in the lower end of said screw rod, in this through hole, be set with and turn round arm, the said aperture of turning round the diameter of arm less than through hole.Further say, for the ease of the rotation of screw rod, be provided with through hole in the bottom of screw rod, this through hole is along the diametric(al) of screw rod and run through screw rod, in through hole, is set with and turns round arm, through increasing the arm of force of rotating screw bolt, has reached the purpose that reduces twisting resistance.
Be provided with at the said two ends of turning round arm and block, the diameter of blocking is greater than the aperture of through hole.Further say; In order to guarantee that turning round arm can be free to slide in through hole, be provided with diameter at the two ends of turning round arm greater than the blocking of through-hole diameter, so; Turning round arm can be free to slide along through hole in through hole, can under the qualification effect of blocking, be unlikely to break away from through hole again simultaneously.
The connecting portion of the connecting portion of described upper clip arm and linking arm and linking arm and lower clip arm all has reinforced company's tape splicing.When the clamping blend stop; In order to increase the chucking power between upper clip arm and the screw rod top; Overcome upper clip arm, lower clip arm because of receiving the deformation that external force produces, be provided with reinforced company's tape splicing at the connecting portion of upper clip arm and linking arm and the connecting portion of lower clip arm and linking arm.
The utility model compared with prior art has following advantage and beneficial effect:
1 the utility model is used for the positioning clamping device of soft workpiece, through the rotation of screw rod in screw, can change the distance between screw rod top and the upper clip arm; Thereby can the adjusting screw(rod) top and upper clip arm between chucking power, promptly make things convenient for the blend stop of different size to change fast, its volume is little, simple to operate; Through increasing the compression area of workpiece; Reduced the pressure that blend stop or surface of the work receive, avoided wood materials under the effect that receives external force and be out of shape, or even damaged; Increase the contact area between grip block and the surfacer platform bottom, reduced the possibility of its slip;
2 the utility model are used for the positioning clamping device of soft workpiece, are provided with through hole in the bottom of screw rod, and this through hole is along the diametric(al) of screw rod and run through screw rod; In through hole, be set with and turn round arm,, reached the purpose that reduces twisting resistance through increasing the arm of force of rotating screw bolt; Be provided with diameter blocking greater than through-hole diameter at the two ends of turning round arm; So, turning round arm can be free to slide along through hole in through hole, can under the qualification effect of blocking, be unlikely to break away from through hole again simultaneously;
