Abstract
A spiral hole puncher belongs to the technical field of chemical experimental apparatuses and comprises a handle and a cylinder knife vertically fixedly connected with the handle, wherein a cylinder body of the cylinder knife is provided with a cylinder body thread of the cylinder knife, and the blade of the cylinder knife is a helical blade. The spiral hole puncher is saved in time and labor, is easy to control and simple in operation during punching. Furthermore, the spiral hole puncher has the advantages of simple structure, low manufacture cost and using cost, and easy popularization.
Description
Technical field:
: the utility model belongs to the chemical experimental instrument technical field, relates to a kind of spiral card punch.
Background technology:
: in chemical experiment, often need on plug, get the hole that varies in size, be used to assign glass tube.And the cylinder cutter blade that traditional card punch generally uses is put down, and when punching, not only requires great effort, but also is prone to deflect, be out of shape, and this has caused very big inconvenience to plug punching work.
The utility model content:
: the purpose of the utility model provide a kind of on plug when punching laborsaving, easy-operating spiral card punch.
: the purpose of the utility model realizes through following technological means: the spiral card punch, to form with the perpendicular cylinder cutter that is fixedly connected by handle, and cylinder cutter stack shell has cylinder cutter stack shell screw thread, and the cylinder blade part is the shape blade in the shape of a spiral.
: the blade of the spiral card punch of the utility model is the shape blade in the shape of a spiral; The operation principle of spiral card punch and the operation principle of screw are similar, and be littler than the resistance of flat blade, therefore can be laborsaving with the punching of spiral card punch; And can not deflect, the plug boring ratio of getting is than standard.
Description of drawings
: Fig. 1 is the utility model sketch map
: wherein 1. handles, 2. cylinder cutter stack shell, 3. cylinder cutter stack shell screw thread, 4. helical form blade
The specific embodiment:
: below in conjunction with accompanying drawing 1 explanation the utility model is done further to describe in detail
: making of this card punch and use: the blade that traditional card punch cylinder cutter stack shell is flat is processed into helical form blade (4); Simultaneously cylinder cutter stack shell is processed to form cylinder cutter stack shell screw thread (3) and links to each other with helical form blade (4); Punch according to traditional card punch hole knockout again, because the change of stack shell and cutting edge shape, so can be laborsaving during the punching of spiral card punch; And can not deflect, can get the plug hole of standard.
Claims (2)
1. the spiral card punch is made up of with the perpendicular cylinder cutter that is fixedly connected handle, and it is characterized in that: cylinder cutter stack shell (2) has cylinder cutter stack shell screw thread (3).
2. spiral card punch according to claim 1 is characterized in that: the blade of cylinder cutter is shape blade (4) in the shape of a spiral.
