Abstract
The utility model discloses a kind of grooved bits with discharge function.It includes the cutting set on drill bit of drill bit and fixing sleeve for drilling, the scraping wings being cased on drill bit in cutting set, it cuts and is provided with annular groove on the inner wall of set, the edge of scraping wings has the position-limited edge extending into annular groove, resetting spring is mounted in annular groove, the bottom of resetting spring is limited in the bottom of annular groove, and the top of resetting spring is pressed on the lower face of position-limited edge, the circumferential surface of cutting set has the guide groove being vertically arranged, and has the operation handle stretched out outside cutting set on scraping wings.With the above structure, the sawdust that can be will focus on after the completion of cutting in cutting set carries out discharge by scraping wings, avoid the problem of traditionally being difficult to clear up to the sawdust being tucked into during punching in cutting set in drill process, the end cap of setting can further be excluded the sawdust for being tucked into cutting set upper space, discharge effect is further improved, the reliability used is improved.
Description
Technical field
The utility model is related to a kind of tool of carpenter's cutting, specifically a kind of grooved bit with discharge function
Head.
Background technology
Grooved bit is widely used in carpenter's cutting operation, and traditional grooved bit generally comprises the drill bit for drilling
And the cutting set for cutting circular hole being arranged outside drill bit, cutting, which is put on, is provided with cutting tooth, in use, being drilled out by drill bit
Centre bore simultaneously forms circular hole by cutting set, and traditional this structure can get circular hole, but since its structure design does not conform to
Reason is generally required often to clear up the sawdust being tucked into during punching in cutting set in drill process, thus be reduced
Operating efficiency.
Invention content
The technical problem to be solved by the present invention is to provide a kind of smart structural designs, and punching is convenient and efficient, operation effect
The high grooved bit with discharge function of rate.
In order to solve the above-mentioned technical problem, the grooved bit with discharge function of the utility model, including be used to drill
Cutting set on drill bit of drill bit and fixing sleeve, be cased with the scraping wings in cutting set on drill bit, cut the inner wall of set
On be provided with annular groove, the edge of the scraping wings has the position-limited edge extending into annular groove, is mounted with resetting spring in annular groove, resets
The bottom of spring is limited in the bottom of annular groove, and the top of resetting spring is pressed on the lower face of position-limited edge, cuts the circumference of set
Surface has the guide groove being vertically arranged, and has the operation handle stretched out outside cutting set on scraping wings.
There is the slot being vertically arranged, the position-limited edge of the scraping wings to be inserted into ring by slot on the inner wall of the annular groove
In slot.
The top of the cutting set is provided with threaded hole, and the cutting set with externally threaded end cap by being mounted on drill bit
On.
After above-mentioned structure, the scraping wings supported by resetting spring cut in set is located at due to setting, by
This is carrying out discharge it is possible thereby to will focus on after the completion of cutting and cut the sawdust in covering by scraping wings, avoids traditionally
The problem of sawdust being tucked into during punching in cutting set is difficult to clear up in drill process, in addition, setting carries spiral shell
The end cap of line can further be excluded the sawdust for being tucked into cutting set upper space, further improve discharge effect,
Improve the reliability used.
