Description
Technical field
The utility model relates to a kind of cutter, specifically, relates to a kind of chipper cutting tool.
Background technology
Current chipper cutting tool, all with screw, cutting tip is fixed on blade holder, cutting tip is provided with two circular fixation hole, and on blade holder, corresponding position is provided with screwed hole, after blade blunt, when needing tool changing, then need the screw of two on blade all to disassemble, and then new blade is installed, operation is more traditional blade exchange mode like this, time-consuming, effort, can not realize the quick-replaceable of blade.
Summary of the invention
The purpose of this utility model be to provide a kind of can the chipper cutting tool of quick-replaceable cutting tip.
In order to solve the problems of the technologies described above, the technical solution of the utility model is,
A kind of chipper cutting tool, comprise cutting tip and blade holder, cutting tip is provided with two fixing holes, on blade holder, correspondence arranges screwed hole, be fixedly connected with by screw between described cutting tip with blade holder, the fixing hole of described cutting tip is rectangular counterbore, and the middle bore of the through hole of this rectangular counterbore is greater than its two ends bore, and described screw is fixed on one end of each rectangular counterbore.
The diameter of head of screw is greater than the through hole two ends bore of rectangular counterbore, is less than through hole middle part bore, blade can be fixed, and when being positioned at through hole middle part, blade can be dismantled when namely head of screw is positioned at through hole two ends.
Further, described blade holder is provided with spring catch, and described spring catch is passed by one end of one of them rectangular counterbore.
Further, described cutting tip has two-sided blade.After blade is pulled down, then 180 degree of rotating blades, an other blade can be used, for the side sending out blunt, after sharpening can be put into.
Wherein, described blade holder is pyramidal structure, and described cutting tip is fixed on its conical surface.
Preferably, described screw is all fixed on the through hole, upper end of each rectangular counterbore, and described spring catch is positioned at the through hole, lower end of the rectangular counterbore in bottom.Like this, when needs removal of inserts, by two several circles of screw loosening, then press spring catch, blade is upwards pushed away namely detachable.
The utility model optimizes the fixed structure of blade, when needs more allowing blade replacement time, screw is not needed to remove, only need a few for screw loosening circle, then spring catch is pressed, cutting tip is pushed to the through hole middle part that head of screw is positioned at rectangular counterbore to the direction that screw fixed position is contrary and can pulls down blade, achieve quick-detachment and the clamping of blade.
The utility model compared with prior art has the following advantages and good effect:
The utility model achieves the quick-replaceable of chipper cutting element, shortens the time of tool changing, improve client's operation comfort, and the fastening strength of blade is unaffected.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Shown in figure 1-3, the present embodiment is a kind of chipper cutting tool, comprise cutting tip 1 and blade holder 2, blade holder 2 is pyramidal structure, its conical surface is arranged with two cutting tips 1, taper tool rest improves stock-removing efficiency, cutting tip 1 is provided with two rectangular counterbores 11, on blade holder 2, correspondence arranges screwed hole 21, be fixedly connected with by screw 3 between cutting tip 1 with blade holder 2, screw 3 is all fixed on the through hole, upper end of each rectangular counterbore 11, blade holder 2 is provided with spring catch 22, spring catch 22 is positioned at the through hole, lower end of the rectangular counterbore in bottom.Like this, when needs dismounting of cutting blade 1, adopt screwdriver to loosen a few circle on two screws 3, then press spring catch 22, cutting tip 1 is upwards pushed away namely detachable simultaneously.As Figure 4-Figure 6, the middle bore R1 of the through hole of this rectangular counterbore 11 is greater than its two ends bore R2, the diameter of head of screw is greater than the through hole two ends bore R2 of rectangular counterbore, be less than through hole middle part bore R1, namely blade can be fixed when head of screw is positioned at through hole two ends, and when being positioned at through hole middle part, blade can be dismantled.
As shown in Figure 4, cutting tip 1 has two-sided blade.After blade is pulled down, then 180 degree of rotating blades, an other blade can be used, for the side sending out blunt, after sharpening can be put into.
The fixing hole of blade has been made into rectangular counterbore pattern by the present embodiment, and on base, fixed blade place adds a spring catch, and blade makes double-sided blade into simultaneously.More during allowing blade replacement, without the need to two screws are all disassembled, only need screw to unclamp a few circle, press spring catch, then blade is upwards pushed away gently, blade can be pulled down, and the key realizing fast-assembling and quick detach is the improper circular hole of blade fixing hole, but " rectangular sample counterbore ", simultaneously with the spring catch of " stop " with the use of " fast-assembling " and " quick detach " that just can realize blade, two-sided blade simultaneously, also can solve the problem that user whets a knife, and improves the comfortableness that user uses.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
