Utility model content
The purpose of this utility model is just to provide the simple in structure, simple operation of one kind and is conducive to novel hand-held used in everyday
Formula pressing rotation card punch.
To achieve the above object, technical solution used by the utility model is：
A kind of hand-held pressing rotation card punch, it is characterised in that:Mainly by handle, be set to the handle bottom by
Pressure pipe is constituted, wherein described to be uniformly arranged several arc-shaped flute profile blades that hole is taken convenient for rotation, the tooth by the nozzle of pressure pipe
Type blade has the gradient to nozzle center, convenient for occlusion medium.
Constituting the additional technical feature that a kind of above-mentioned hand-held pressing rotates card punch further includes：
--- described by plunger tip bar is set inside pressure pipe, the plunger tip bar has pushing block outstanding, the pipe shaft by pressure pipe
The sliding slot of ejection circular hole core is made in upper setting for the pushing block, and the plunger tip rod set shock mount, one end of the spring is limited to
The other end of the pushing block bottom of the plunger tip bar, the spring is limited in the ring body by pressure pipe lower inside protrusion, institute
State thickness of the compression distance at least equal to circular hole core of spring；
--- the handle is made of the cross bar convenient for holding with the pipe sleeve being vertically installed in the middle part of the cross bar, described to press
Pressure pipe is set in inside the pipe sleeve, and the handle is made of rigid plastics, described to be made of stainless steel by pressure pipe and blade.
A kind of hand-held pressing rotation card punch provided by the utility model compared with prior art, has following excellent
Point：First, since the card punch mainly by handle and is set to being constituted by pressure pipe for handle bottom, it is uniform by the nozzle of pressure pipe
Several arc-shaped flute profile blades that hole is taken convenient for rotation are set, and flute profile blade has the gradient to nozzle center, convenient for occlusion
Medium has the characteristics that simple in structure, pressing rotation punching is efficient and convenient；Second, there is setting pushing block due to pressing inside pressure pipe
Plunger tip bar, by the pipe shaft of pressure pipe setting for pushing block do ejection circular hole core sliding slot, plunger tip rod set shock mount, push pushing block
Plunger tip bar may be implemented in pressing inner telescoping tube, the circular hole core that punching is formed, which is released, presses pressure pipe, convenient to punch again, has
The characteristics of simple operation；Third, due to handle by convenient for holding cross bar and the pipe sleeve that is vertically installed in the middle part of cross bar constitute, press
Pressure pipe is set in inside the pipe sleeve, and handle is made of rigid plastics, is made of stainless steel by pressure pipe and blade, small and flexible,
Production is simple, and cheap, handheld operation is handy.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of hand-held pressing rotation card punch of the utility model.
Specific implementation mode
Structure to a kind of hand-held pressing rotation card punch provided by the utility model and work below in conjunction with the accompanying drawings
Principle is described in further detail.
As shown in Figure 1, for a kind of structural schematic diagram of hand-held pressing rotation card punch provided by the utility model.Structure
At the structure of the card punch mainly by handle, it is set to being constituted by pressure pipe 2 for handle bottom, wherein uniform by the nozzle of pressure pipe 2
Several arc-shaped flute profile blades 21 that hole is taken convenient for rotation are set, and flute profile blade 21 has the gradient to nozzle center, is convenient for
It is engaged medium.
Its working principle is that：It holds with a firm grip handle, hard medium to be punctured will be directed at by pressure pipe 2（Soft medium needs gasket
Cooperation）, compressing is made by pressure pipe 2 inside 21 embedding medium of arc dentation blade of nozzle, to improve drilling efficiency, in pressing process
Middle rotating handles, arc dentation blade 21 cut the boring sites in curing of medium.
In the structure for constituting a kind of above-mentioned hand-held pressing rotation card punch,
--- it is released in time by the circular hole chip inside pressure pipe 2 by pressure pipe 2 to punch to be retained in, it is above-mentioned to press pressure pipe 2
Inside sets plunger tip bar 22, and plunger tip bar 22 has pushing block 221 outstanding, and ejection circle is done for pushing block 221 by setting on the pipe shaft of pressure pipe 2
The sliding slot 23 of hole core, 22 pocketed springs 24 of plunger tip bar, one end of the spring 24 are limited to the pushing block 221 of the plunger tip bar 22
Bottom, the other end of the spring 24 are limited in the ring body 25 by pressure pipe 2 lower inside protrusion, the compression of spring 24 away from
From the thickness at least equal to circular hole core, after completing to punch, mobile pushing block 221 makes plunger tip bar 22 that circular hole chip is released pressing
Plunger tip bar 22 is limited to the inside by pressure pipe 2 again, does not influence drilling operation next time by pipe 2, the reset of spring 24；
--- in order to easily facilitate hand-held, above-mentioned handle by convenient for holding cross bar 11 and be vertically installed in cross bar 11
The pipe sleeve 12 at middle part is constituted, and pressing rotation punch operation can be completed in one hand, is particularly suitable for routine use, is set in by pressure pipe 2
Inside pipe sleeve 12, handle is made of rigid plastics, is made of stainless steel by pressure pipe 2 and blade 21, and overall cost is cheap, small and exquisite light
Just, it is handicraftsman's serviceable tools.
