Abstract
The invention discloses an independent cutter of a curtain hole punch. The independent cutter comprises a main shaft and a blade, and further comprises a hollow outer sleeve with the lower end open and a cloth pressing cylinder coaxially sleeved with the outer sleeve. The lower end of the main shaft penetrates through the cloth pressing cylinder, the cloth pressing cylinder is installed on the main shaft through the lower end of the main shaft, and the upper end of the outer sleeve is fixedly installed on the main shaft. An elastic device for supplying elasticity when the cloth pressing cylinder moves up and down is arranged between the upper end of the cloth pressing cylinder and the upper wall inside the outer sleeve. The blade is a cylindrical blade arranged around the outer sleeve. The upper end of the blade is connected with the lower end of the outer sleeve, and the lower end of the blade is a non-plane-port-shaped cutting edge. In the non-working state, the cloth pressing end of the cloth pressing cylinder extends out of the lower end of the blade. The independent cutter of the curtain hole punch has the advantages that the structure is compact and simple, the blade does not need to be replaced or dismounted or mounted, the cutting edge is sharp, time and labor are saved, the curtain hole punching quality is good, and the independent cutter can be widely popularized and used.
Description
Technical field
The present invention relates to curtain puncher parts, be specifically related to a kind of curtain puncher stand alone type cutter.
Background technology
People, in the time making curtain, in order to facilitate curtain to be suspended on curtain rod, need punch at the top of curtain.Along with scientific and technological progress, various curtain puncheres are designed in people's invention, by adopting curtain puncher to substitute the most original pure manual punching work, have not only greatly improved the efficiency of curtain punching, have also saved the time.And no matter be mechanical type curtain puncher or electrodynamic type curtain puncher, cutter is all one of its requisite critical component.The cutter that the curtain puncher of prior art uses has following shortcoming:
1, the cutter of existing electrically driven curtain puncher is to be generally directly fixedly connected on main frame, in the time that cutter occurs heavy wear or will change the cutter of different model, is difficult to dismounting and change;
2, the blade of existing curtain puncher is flat pointed tool, and because the edge of a knife and the cloth contact-making surface of blade are excessive, when punching, large, the edge of a knife of resistance easily generates heat, and cutting speed is slow, and cloth bits after the cutting of circular cartridge type flat pointed tool easily enter in cutter hub, not easy-clear; Or for blade is flat, blade lower end is provided with cutting tips, blade is fragile, often dismounting, replacing, waste time and energy.
Summary of the invention
For above-mentioned deficiency, technical problem to be solved by this invention is to provide a kind of good stability, easy for installation, does not need dismounting, allowing blade replacement more, cuts sharp curtain puncher stand alone type cutter.
For addressing the above problem, the present invention is achieved through the following technical solutions:
A kind of curtain puncher stand alone type cutter, comprise main shaft and blade, also comprise hollow sleeve cylinder and the compress cylinder of coaxial sleeve in outer sleeve of lower ending opening, the lower end of described main shaft is passed compress cylinder and compress cylinder is arranged on main shaft, and the upper end of described outer sleeve is packed on main shaft; In compress cylinder upper end and outer sleeve, between upper wall, be provided with the elastic device that elastic force is provided in the time that compress cylinder moves up and down, described blade is the cylindrical blade of establishing around outer sleeve ring, the upper end of blade is connected with outer sleeve lower end, blade lower end is non-flat mouth shape blade, in off working state, the compress end of compress cylinder stretches out the lower end of blade.
In described outer sleeve, be provided with and be enclosed within the anti-skidding device in order to prevent that compress cylinder from sliding on main shaft, described anti-skidding device comprises bearing and two concentric settings, the different annular gasket of diameter, and described pad is enclosed within bearing and the large pad of diameter is positioned at the top of the pad that diameter is little.
In such scheme, described elastic device can be spring, and the upper end of this spring is pressed on anti-skidding device upper and lower end and is pressed on compress cylinder.
Described non-flat mouth shape blade is waveform blade.
Beneficial effect of the present invention is:
1, the two telescopic cutter that this curtain puncher stand alone type cutter is mainly made up of main shaft, outer sleeve, compress cylinder and blade, when use, the main shaft of cutter being inserted to drill chuck tightens, there is compact conformation and simple, without changing, dismounting blade, time saving and energy saving feature;
2, the blade that this curtain puncher stand alone type cutter uses is that cylindrical shape, the blade of establishing around outer sleeve ring is the blade of non-flat mouth shape, cuts sharp, not fragile;
3, in the outer sleeve of this curtain puncher stand alone type cutter, be provided with and be enclosed within the anti-skidding device in order to prevent that compress cylinder from sliding on main shaft, make whole cutter good stability in the time of work, curtain drilling quality is good.
Brief description of the drawings
Fig. 1 is the positive view of this curtain puncher stand alone type cutter.
Fig. 2 is the side view of the blade of this curtain puncher stand alone type cutter.
Number in the figure is: 1, main shaft; 2, outer sleeve, 3, compress cylinder; 4, blade; 5, spring; 6, anti-skidding device.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments the present invention will be further explained explanation, but do not limit the present invention.
As shown in Figure 1, a kind of curtain puncher stand alone type cutter, comprise main shaft 1 and blade 4, also comprise hollow sleeve cylinder 2 and the compress cylinder 3 of coaxial sleeve in outer sleeve 2 of lower ending opening, the lower end of described main shaft 1 is through compress cylinder 3, and compress cylinder 3 is arranged on main shaft 1, the upper end of described outer sleeve 2 is packed on main shaft 1, in outer sleeve 2, be provided with and be enclosed within the anti-skidding device 6 in order to prevent that compress cylinder 3 from sliding on main shaft 1, this anti-skidding device 6 can be bearing or other fixed part, in the present embodiment, described anti-skidding device 6 is the applicant oneself design, have anti-slip effective, feature with low cost, it comprises bearing and two concentric settings, the annular gasket that diameter is different, described pad is enclosed within bearing, and the pad that diameter is large is positioned at the top of the pad that diameter is little.Between compress cylinder 6 upper ends and the interior upper wall of outer sleeve 2, be provided with the elastic device that elastic force is provided in the time that compress cylinder 3 moves up and down, in the present embodiment, described elastic device is preferably spring 5, and the upper end of this spring 5 is pressed on anti-skidding device 6 upper and lower ends and is pressed on compress cylinder 3.Described blade 4 is for to encircle the cylindrical blade of establishing around outer sleeve 2, the upper end of blade 4 is connected with outer sleeve 2 lower ends, blade 4 lower ends are non-flat mouth shape blade, non-flat mouth shape blade can be zigzag, waveform or other non-flat mouth shape blades, in the present embodiment, described non-flat mouth shape blade is waveform blade, and the side view of blade as shown in Figure 2.In off working state, the compress end of compress cylinder 3 stretches out the lower end of blade 4.
