The compass knife has the beneficial effects that the structure is simple, the detaching is convenient, the operation is easy, an operator can fast position the center of a circle and accurately adjust the diameter of the cut circle, links, such as drawing a circle and wiping handwriting are omitted, the radial adjusting part is arranged at one side of the sucking disc assembly, the operating space can be reduced, the working efficiency is improved, and the cutting precision is ensured.
Description
Technical field
The utility model relates to a kind of cutting tool, specifically a kind of compasses cutter that cuts circular element that is exclusively used in.
Background technology
If want the raw material of materials such as crystal slab, plastics, rubber, paper, cloth are cut into circle, original method of operating is to find the center of circle with ruler earlier on by the sanction object, get one section non-retractable rope again, rope one end is fixed on the nail, and the other end is provided with detail pen, and the tip of nail is fixed on the center of circle that finds, detail pen is around center of circle setting-out, the length of rope is circular radius, cuts along the line with cutter after finishing again, and also the trace line of detail pen will be wiped at last.Doing each link like this wastes time and energy, and because be pure manual operations, track has deviation when utilizing the cutter cutting, and it is low to cut precision, and not attractive in appearance.
Summary of the invention
Defectives such as the purpose of this utility model provides a kind of compasses cutter, overcomes the precision that exists when the tradition means of cutting cut circular element and is difficult to control, and the edge is unsmooth, and is not attractive in appearance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of compasses cutter, formed by sucker assembly, cutter head and scale, described sucker assembly comprises holder and sucker, described holder and scale are slidingly connected, and holder is provided with retaining mechanism, retaining mechanism can be locked in scale on the holder, described cutter head is fixed on the scale end, holder is provided with movable pointer, the stiff end of movable pointer arranges chute, screw passes chute movable pointer is fixed on the holder, can proofread and correct the reading of compasses cutter by the position of fine setting movable pointer.
As preferably, described sucker assembly also comprises the attached dish of sucker, and the attached dish of sucker and sucker removably connect.
The through hole that adapts with the scale cross section is set on the described holder, and scale passes from through hole, and the retaining mechanism that arranges at holder is trip bolt.
Described cutter head comprises handle of a knife, blade, branch sleeve, and described handle of a knife one side is provided with outstanding joint pin, and joint pin inserts in the branch sleeve, and the other end of branch sleeve is connected to scale, and branch sleeve is provided with lock-screw and hand is tightened fixing bolt.
Described scale is provided with scale.
The beneficial effects of the utility model are:
The utility model is simple in structure, convenient disassembly, processing ease, the operator can locate the center of circle fast and accurately regulate and cut diameter of a circle, saved links such as drawing circle and wiping person's handwriting, adjusting place of radius can reduce the operating space as for sucker assembly one side, increase work efficiency, and guarantee to cut precision.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram of sucker assembly in the utility model.
Fig. 3 is the structure for amplifying schematic diagram of cutter head part in the utility model.
Among the figure: 1, sucker assembly; 11, holder; 12, sucker; 13, the attached dish of sucker; 14, sucker driving lever; 15, trip bolt; 2, cutter head; 21, handle of a knife; 22, blade; 23, branch sleeve; 24, lock-screw; 25, hand is tightened fixing bolt; 3, scale.
The specific embodiment
As shown in Figures 1 to 3, a kind of compasses cutter, formed by sucker assembly 1, cutter head 2 and scale 3, described sucker assembly 1 comprises holder 11 and sucker 12, described holder 11 is slidingly connected with scale 3, and holder 11 is provided with retaining mechanism, and retaining mechanism can be locked in scale 3 on the holder 11, and described cutter head 2 is fixed on scale 3 ends.
As preferably, described sucker assembly 1 also comprises the attached dish 13 of sucker, and the attached dish 13 of sucker removably connects with sucker 12.If when object to be processed is the material of surface smoothings such as plastics or crystal slab, need not to use the attached dish 13 of sucker, can guarantee that sucker 12 can be adsorbed on the surface of object to be processed securely; When if the material of object to be processed is paper or cloth, need be by the attached dish 13 of sucker, the attached disc area of sucker is big, and has good adsorptivity, thereby guarantees the stability of holder 11, prevents that the center of circle is offset in the process of cutting.
The through hole that adapts with the scale cross section is set on the described holder 11, and scale 3 passes from through hole, and the retaining mechanism that arranges at holder is trip bolt 15.
Above holder 11, be provided with sucker driving lever 14, be used for the adsorbed state between control sucker 12 and the object to be processed.
Described cutter head 2 comprises handle of a knife 21, blade 22, branch sleeve 23, described handle of a knife one side is provided with outstanding joint pin, joint pin inserts in the branch sleeve, the other end of branch sleeve 23 is connected to scale 3, branch sleeve is provided with lock-screw 24 and hand is tightened fixing bolt 25, lock-screw 24 is used for the relative position of adjusting and nonadjustable signal 3 and branch sleeve 23, and hand is tightened the relative position that fixing bolt 25 is used for regulating connecting rod and branch sleeve 23.If there are deviation in circular element actual size and the rod reading of the cutting of compasses cutter, can regulate herein, make its error close to zero.In addition, under non-working condition, scale 3 and cutter head partly can be taken apart, be convenient to deposit and carry.
Described scale 3 is provided with scale.
Using method is as follows: one, regulate the relative position of scale 3 and holder 11, and fixing by trip bolt 15, thus the radius of definite circle of contact to be cut; Two, sucker 12 is absorbed and fixed at the surface of object to be processed, sucker 12 centers of circle are the center of circle of the circle of contact to be cut; Three, press cutter head and also rotate a week around holder, can cut out desirable circular element.
Sucker assembly absorption is automatically cut out object, and scale can clearly allow the operator find the diameter of a circle that will cut, and cutter head is stiff, guarantees to cut precision.
The utility model is simple in structure, convenient disassembly, processing ease, the operator can locate the center of circle fast and accurately regulate and cut diameter of a circle, saved links such as drawing circle and wiping person's handwriting, the adjusting device of radius places sucker assembly one side, can reduce the operating space, increase work efficiency, and guarantee to cut precision.
More than disclosed be the specific embodiment of this patent only, but this patent is not limited thereto, for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, the distortion of making should be considered as belonging to the utility model protection domain.
