Abstract
The utility model discloses screw scissors which enable sheared screws to be flat and smooth in fractured opening. The screw scissors comprise a base, a stationary blade which is fixed on the base, a moving blade which is arranged on the stationary blade and matched with the stationary blade, an upper pipe which is hinged to the base and a lower pipe which is fixed on the base; a waist-shaped hole is formed in the upper pipe; one side of the moving blade is connected with a connecting plate; a guiding pin is arranged on the connecting plate; the guiding pin is arranged in the waist-shaped hole which is formed in the upper pipe; the stationary blade is provided with a stationary shearing edge which accommodates the screws; the moving blade is provided with a moving shearing edge which accommodates the screws and is matched with the moving shearing edge; a supporting hook is hinged to the base through a torsional spring; the stationary blade is arranged between the moving blade and the supporting hook; a push block is arranged on the upper pipe; the push block can push the supporting hook to rotate and enable a bending portion of the supporting hook to rotate to be in a straight line with the stationary shearing edge and the moving shearing edge. The screw scissors have the advantages of enabling the screws to be fixed through the supporting hook, accordingly guaranteeing the screws not rotate when being influenced by shearing twisting force, guaranteeing flat and smooth screw fractured openings and improving screw aesthetic feeling and utilization.
Description
Technical field
The utility model relates to a kind of threaded rod shear.
Background technology
Conventional threaded rod shear, comprise base, be fixed on stationary knife on base, rotate and be arranged on the moving knife that matches on stationary knife and with stationary knife, be hinged on the upper pipe on base and be fixed on the lower pipe on base, on upper pipe, be provided with mounting hole, one side of moving knife is connected with connecting plate, on connecting plate, be provided with guide finger, guide finger is arranged in the mounting hole of pipe, is provided with the sheared edge of determining of holding screw rod on stationary knife, on moving knife, be provided with hold screw rod and with the moving sheared edge of determining sheared edge and matching.This threaded rod shear is when reality is used, because being placed on, determines in sheared edge and moving sheared edge screw rod, in shearing, the torsion that screw rod can be sheared is because determine sheared edge and moving sheared edge in order to adapt to the screw rod of plurality of specifications, conventionally all large than screw diameter, screw rod is easy rotation in the effect that is subject to the resistance of cutting so, after cutting like this, the fracture of screw rod will tilt and out-of-flatness, affects like this attractive in appearance of screw rod and uses.
Utility model content
Technical problem to be solved in the utility model is: a kind of smooth, smooth threaded rod shear of fracture of shearing rear screw rod is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of threaded rod shear, comprise base, be fixed on the stationary knife on base, rotation is arranged on the moving knife matching on stationary knife and with stationary knife, be hinged on the upper pipe on base and be fixed on the lower pipe on base, on upper pipe, be provided with mounting hole, one side of moving knife is connected with connecting plate, on connecting plate, be provided with guide finger, guide finger is arranged in the mounting hole of pipe, on stationary knife, be provided with the sheared edge of determining of holding screw rod, on moving knife, be provided with hold screw rod and with the moving sheared edge of determining sheared edge and matching, on described base, be hinged with hook by torsion spring, stationary knife is between moving knife and hook, on upper pipe, be provided with and can promote hook rotation and the bend of hook can be turned to and determine sheared edge, the pushing block of moving sheared edge one straight line.
On described hook, be provided with the block offseting with pushing block.
The beneficial effects of the utility model are: utilize hook that screw rod is fixed, thereby can ensure that screw rod can not be subject to the resistance of cutting affect and rotate in shearing, thereby ensure the smooth, smooth of screw rod fracture, improve the attractive in appearance of screw rod and use.

Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, Figure 2, Figure 3 shows, threaded rod shear described in the utility model, comprise base 1, be fixed on stationary knife 2 on base 1, rotate and be arranged on the moving knife 3 that matches on stationary knife 2 and with stationary knife 2, be hinged on the upper pipe 4 on base 1 and be fixed on the lower pipe 5 on base 1, on upper pipe 4, be provided with mounting hole (not shown in FIG.), one side of moving knife 3 is connected with connecting plate 6, on connecting plate 6, be provided with guide finger (not shown in FIG.), guide finger is arranged in the mounting hole of pipe 4, like this in pressing pipe 4 downwards, moving knife 3 will rotate, and this is routine techniques.On stationary knife 2, be provided with hold screw rod 7 determine sheared edge 8, on moving knife 3, be provided with hold screw rod 7 and with the moving sheared edge 9 of determining sheared edge 8 and matching, on described base 1, be hinged with hook 11 by torsion spring 10, stationary knife 2, between moving knife 3 and hook 11, is provided with the pushing block 13 that can promote that hook 11 rotates and the bend of hook 11 12 can be turned to and determine sheared edge 8, moving sheared edge 9 one straight lines on upper pipe 4.Promote hook 11 for the ease of pushing block 13 and rotate, on described hook 11, be provided with the block 14 offseting with pushing block 13.
The course of work of the present utility model is: as Fig. 1, Fig. 2, shown in Fig. 3, now threaded rod shear is in duty not, first will on upper pipe 4, lift, upper like this pipe 4 passes through mounting hole, guide finger and connecting plate 6 rotate moving knife 3, move sheared edge 9 and determine sheared edge 8 and open, along with the rotation of upper pipe 4, after contacting with block 14 at pushing block 13, just hook 11 is pressed down, until being positioned at, the bend 12 of hook 11 determines sheared edge 8 belows, then screw rod 7 is placed on and determines between sheared edge 8 and moving sheared edge 9, then press down pipe 4, hook 11 rotates backward under the effect of torsion spring, after determining to have put screw rod 7 between sheared edge 8 and moving sheared edge 9, the bend 12 of hook 11 is encountered screw rod 7 in the time rotating backward, and bend 12 catches on screw rod 7, under continuation, press pipe 4, thereby realize, screw rod 7 is sheared, in the process of shearing, owing to there being bend 12 that screw rod is caught on, like this in moving sheared edge 9 with determine in sheared edge 8 shears screw rod 7, screw rod 7 can not rotate under the effect of hook 11, thereby ensure that shearing force is vertical screw 7 all the time, the section of the screw rod 7 after shearing is so exactly smooth, smooth, thereby improve the attractive in appearance of screw rod 7 and reduce moving knife, the service life of stationary knife.
