The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

As depicted in figs. 1 and 2, the present embodiment comprises base plate 1, clamp body 2, hollow locating shaft 5, piston A 10, extrusion ball 4, flexible ball 3, lever 9, piston B 8, screw 7 and with the latch 6 of spring 11.It is coaxial and with positioning shaft hole A and the positioning shaft hole B of diameter that the center of base plate 1 and clamp body 2 has.Base plate 1 surrounding has a plurality of equal dividing and positioning blind holes 12, and clamp body 2 is having pin hole 15 with equal dividing and positioning blind hole 12 with the position of diameter.It is the through hole that screw hole, bottom are piston hole that the periphery lower end of base plate 1 has top, and in through hole, bottom is provided with piston B 8, top screw thread is fixed with screw 7.Hollow locating shaft 5 is fixed in the positioning shaft hole A of base plate 1, is through in the positioning shaft hole B of clamp body 2.The hollow piston A 10 matching and the extrusion ball 4 that in hollow locating shaft 5 endoporus, are placed with successively diameter and hollow locating shaft, its upper end evenly has three flexible ball holes, lays respectively flexible ball 3 in flexible ball hole.Between the positioning shaft hole A of base plate 1 and through hole, have lever slot 13, lever 9 one end are inserted in the groove that piston A bottom has, and the other end is inserted in the groove that piston B bottom has, and intermediate support is inserted in holder 14, and holder 14 is fixed in lever slot 13.Surface cover is installed in the pin hole of clamp body 2 latch 6 of spring 11.Extrusion ball 4 and flexible ball 3 are all steel ball.The present embodiment also can arrange a plurality of flexible balls holes such as four, five as required.

During use, clamp body 2 links together by locating shaft 5 and base plate 1, and can rotate around locating shaft 5.At fixture releasing orientation, pull up latch 6, clamp body 2 can rotate around locating shaft 5, and when clamp body 2 forwards sub-degree angle to, latch 6 completes calibration one time in spring 11 acts on one of them the equal dividing and positioning blind hole 12 that falls into base plate 1.When turning screw 7 and move down, piston B 8 and then moves down, by lever 9, piston A 10 is moved up, while moving on piston A 10, drive extrusion ball 4 to move up, push three flexible balls 3 along completing locking process on the protruding conical surface that is pressed in clamp body 2 in three uniform holes on locating shaft 5.While unclamping, only need turn screw 7 and move up, piston B 8 and then moves up, and by lever 9, piston A 10 is moved down, and extrusion ball 4 also moves down, and three flexible balls 3 also and then unclamp, and complete release process.By the difference of design lever 9 point of rotation two ends arm of force length, according to lever principle, operator only needs less screwing force just can obtain enough clamping forces.Unclamp clamping and only need turn screw 7, realized Quick-clamped.
