Operation principle of the present utility model is: during use, hold three handles symmetrical on housing, stressed radially-inwardly the moving to along housing in handle one end is close to housing, the other end of handle moves around the opposite direction of bearing pin towards handle one end motion together with the locating dowel be vertically connected on handle, and locating dowel is lifted thus long and short jaw under leaving locating hole and locating hole.Tubular workpiece is put into this spring perch from the openend of housing, rotate rotary head, the long jaw of the locating hole on rotary head and the interior correspondence of locating hole and the also corresponding rotation of short jaw, choose required position, release handle, handle is returned to origin-location by spring, handle rotates around bearing pin, one end of handle also returns to original position, and locating dowel to be inserted in locating hole and compressed corresponding long jaw or short jaw, makes long jaw or short jaw is stressed inwardly firmly clamps tubular workpiece.
Compared with prior art the beneficial effects of the utility model are: 1. three hold down gags are symmetrically distributed in hull outside, determine that the principle of one side firmly can fix round piece according to 3, and three clamping devices are symmetrical, when can make to hold firmly evenly.2. the hold down gag handle that comprises the spring be fixedly connected on housing, offset with spring, locating dowel connected vertically with handle, locating dowel radially-inwardly stretches along housing, handle by hinge on the boss of housing, by lever principle, making in use can be laborsaving.3. in the correspondence position of the locating hole of rotary head, crossed-symmetrical is provided with long jaw and short jaw, and long jaw and short jaw are the tooth-shape structure be hinged in housing, can position clamping selectively, accurate positioning.4. the utility model only comprise rotary head, the housing that is socketed with rotary head, bearing pin and three hold down gags being symmetrically distributed in hull outside, structure is simply small and exquisite, is easy to carry.
Further, the part that offsets of described handle and spring, for arcuate structure, facilitates handle and spring to offset.
Further, the bottom surface of described long jaw is the cirque structure matched with housing inscribed circle, and long jaw is slidably connected on housing by bolt, facilitates long jaw along bolt along the radial motion of housing.
Further, the bottom surface of described short jaw is the cirque structure matched with housing inscribed circle, and long jaw is slidably connected on housing by bolt, facilitates short jaw along bolt along the radial motion of housing.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of a kind of spring perch embodiment of the utility model;
Fig. 2 is the top view of the rotary head of a kind of spring perch embodiment of the utility model;
In figure, Reference numeral is: rotary head 1, handle 2, spring 3, housing 4, locating hole 5, bearing pin 6, locating dowel 7, short jaw 8, long jaw 9, workpiece 10.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated, but not as to restriction of the present utility model.
As shown in Figure 1, a kind of spring perch, the housing 4 comprise rotary head 1, being socketed with rotary head 1, bearing pin 6 and three hold down gags be symmetrically distributed on outside housing 4, housing 4 is the column structure of hollow, the lateral wall of housing 4 is radially symmetrically welded three boss, housing 4 right-hand member and rotary head 1 are socketed, and rotary head 1 have radial equally distributed locating hole 5, and housing 4 left end is that hatch frame enters for workpiece 10; The handle 2 that hold down gag comprises the spring 3 be welded on housing 4, offsets with spring 3, with the locating dowel 7 of handle 2 vertical welding, locating dowel 7 radially-inwardly stretches along housing 4, and handle 2 is hinged on the boss of housing 4 by bearing pin 6.As shown in Figure 2, in the correspondence position of rotary head 1 locating hole 5, crossed-symmetrical is provided with long jaw 9 and short jaw 8, and long jaw 9 and short jaw 8 are the tooth-shape structure be hinged in housing 4.
Handle 2 is arcuate structure with the part that offsets of spring 3, facilitates handle 2 and spring 3 to offset.The bottom surface of long jaw 9 and short jaw 8 is the cirque structure matched with housing 4 inscribed circle, and long jaw 9 and short jaw 8 are all slidably connected on housing 4 by bolt, and the convenient direction along bolt is along the radial motion of housing 4.
During use, hold three handles 2 symmetrical on housing 4, stressed radially-inwardly the moving to along housing 4 of handle 2 left end is close to housing 4, the opposite direction motion that the right-hand member of handle 2 moves towards handle 2 left end around bearing pin 6 together with the locating dowel 7 be vertically welded on handle 2, locating dowel 7 is lifted thus long and short jaw under leaving locating hole 5 and locating hole 5.Tubular workpiece 10 is put into this spring perch from the left end opening of housing 4, rotate rotary head 1, the long jaw 9 of the locating hole 5 on rotary head 1 and the interior correspondence of locating hole 5 and short jaw 8 also corresponding rotation, choose required position, release handle 2, handle 2 is returned to origin-location by spring 3, handle 2 rotates around bearing pin 6, the right-hand member of handle 2 also returns to original position, locating dowel 7 to be inserted in locating hole 5 and is compressed corresponding long jaw 9 or short jaw 8, makes long jaw 9 or short jaw 8 is stressed inwardly firmly clamps tubular workpiece 10.
