Abstract
The utility model discloses a small-size puncher, it includes the bottom plate, fixes collateral branch frame, handle on the bottom plate, punches head and transmission shaft, and the transmission shaft links firmly with the handle, and the transmission shaft is fixed on the collateral branch frame with the equal activity of the head of punching, and two ends of transmission shaft are equipped with a plurality of axial recesses, punches the head and corresponds the position and also be equipped with a plurality ofly and the radial recess of transmission shaft recess assorted, through the transmission shaft recess with punch the first recess, make the head of punching and transmission shaft meshing. In the small-sized perforating machine, the perforating head is cylindrical, and one end face of the perforating head is provided with the elliptic concave surface. And one side surface of the bottom plate is provided with a scale. The transmission structure can simplify the structure of the perforating machine and reduce the abrasion of the transmission mechanism. An elliptical concave surface is arranged on one end surface of the cylindrical punching head, so that the cutter head is sharp and wear-resistant. In addition, a scale is arranged on one side surface of the bottom plate, so that the perforating machine is more convenient to use.
Description
Technical field
The utility model relates to a kind of office equipment, especially a kind of small-sized puncher.
Background technology
Puncher is used to punching bindings such as stacked bill, data as a kind of office appliance.Generally comprise base plate, be fixed on side stand, handle, punching head and drive mechanism on the base plate as the armstrong's patent puncher, existing this puncher often exists a punching sharp face easy to wear, the big deficiency that waits in transmission mechanism gap.State Intellectual Property Office's on July 9th, 2003 disclosed " a kind of puncher " patent documentation, introduced a kind of puncher, comprise base plate, two stands, be embedded in last knife plate on the two stands, the handle of knife plate action in the control, and with the guide plate of the supporting setting of last knife plate, holding plate, knife plate down, be characterized in, two stands is built-in support, the last knife plate that is embedded on the two stands is two, with the guide plate of the supporting setting of last knife plate, holding plate, knife plate is two covers down, also comprises connecting axle and resetting-mechanism.The handle of this puncher directly contacts the application of force with last knife plate, makes the transmission distance of moment be reduced to zero, has avoided the generation of moment of torsion, thereby has prolonged the service life of machine, has reduced maintenance time, but has had baroque deficiency.
Summary of the invention
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of simple for structure, small-sized puncher that the transmission mechanism gap is little, easy to use.
For addressing the above problem, the utility model is by the following technical solutions: a kind of small-sized puncher, it comprises base plate, is fixed on side stand, handle, punching head and power transmission shaft on the base plate, described power transmission shaft and handle are connected, described power transmission shaft and punching head all activity are fixed on the side stand, described power transmission shaft two ends are provided with a plurality of axial notches, a described punching corresponding position also is provided with a plurality of grooves radially that are complementary with the power transmission shaft groove, by a power transmission shaft groove and a punching groove, make the punching head meshing with power transmission shaft.
Above-mentioned small-sized puncher, described punching head is cylindrical, an one end face is provided with oval-shaped concave surface.A side of described base plate is provided with scale.
Owing to adopted said structure, power transmission shaft and punching head are equipped with a plurality of grooves that are complementary, by a power transmission shaft groove and a punching groove, make the punching head meshing with power transmission shaft, this drive mechanism makes puncher simple in structure on the one hand, on the other hand, can also reduce the wearing and tearing of transmission mechanism.An end face at cylindrical punching head is provided with oval-shaped concave surface, makes cutter head sharp, wear-resisting.In addition, be provided with scale in a side of base plate, it is more convenient that puncher is used.
Description of drawings
Fig. 1 is the structural representation of the small-sized machine that fans the air of the present utility model;
Fig. 2 is the structural representation of cutter head.
Among the figure: 1-base plate, 2-side stand, 3-handle, the 4-head that punches, 5-power transmission shaft, 6-power transmission shaft groove, the 7-groove that punches, the oval concave surface of 8-punching end surface, 9-scale.
The specific embodiment
As shown in Figure 1, a kind of small-sized puncher of the present utility model, it comprises base plate 1, be fixed on two side stands 2 on the base plate 1, handle 3, punching 4 and power transmission shaft 5, described power transmission shaft) is connected with handle (3), a described power transmission shaft 5 and punching 4 an equal activity are fixed on the side stand 2, described power transmission shaft (5) two ends are provided with a plurality of axial notches 6, described punching 4 corresponding position also are provided with a plurality of grooves radially 7 that are complementary with power transmission shaft groove 6, by a power transmission shaft groove 6 and a punching groove 7, make the punching head meshing with power transmission shaft.
Referring to Fig. 2, above-mentioned small-sized puncher, punching 4 is cylindrical, an one end face is provided with oval-shaped concave surface 8.Base plate 1 side is provided with scale 9 in addition, can measured hole when fanning the air and the distance of margin.
Claims (3)
