Description
Technical field
A kind of screw tap structure is the utility model is related to, is specially a kind of screw tap structure with helicla flute, belonging to machinery should
Use field.
Background technology
Screw tap is a kind of cutter of machining internal thread, can be divided into spiral tap and straight sword screw tap according to shape, according to making
It can be divided into set tap and machine tap with environment, can be divided into metric system according to specification, it is made in U.S.A, and screw tap made in Great Britain, according to production
Ground can be divided into import screw tap and domestic screw tap.Screw tap is the main instrument that manufacturing industry operator processes screw thread, and wherein hand
More extensive compared to machine tap use scope with screw tap, simultaneously as set tap is cheap, user is most of
It is the new hand for not using experience, therefore, the environment that set tap faces is also more complicated than machine tap.
But existing screw tap still has certain defect when in use, existing set tap is due to unlike machine tap
The depth of bit bore can be accurately controlled by computer like that, but is added by construction personnel by eyesight and experience
Work, the depth for causing bit bore be not it is too deep be exactly it is shallow, be unable to reach construction requirement all the time, seriously affected construction speed
And construction quality.
Utility model content
The purpose of this utility model is that to solve the above-mentioned problems and provides a kind of screw tap structure with helicla flute.
The utility model is achieved through the following technical solutions above-mentioned purpose, a kind of screw tap structure with helicla flute, bag
Drill bit is included, the drill bit internal sets helicla flute, drill bit side mounting and fixing support, and described drill bit one end sets connector,
First threaded hole is set inside the fixed frame, the first convex block, the first convex block top installation are installed inside the fixed frame
Stent, the internal stent set sliding slot, and the second convex block is set above the sliding slot, sliding block is installed inside second convex block,
Described sliding block one end sets connecting hole, and pointer is installed inside the connecting hole, the second threaded hole is set inside the pointer.
Preferably, in order to enable first convex block to be accurately positioned inside the fixed frame, inside the fixed frame
Set fluted.
Preferably, in order to make first convex block not fallen off when with the bit, the fixed frame and institute
State between the first convex block in being bolted.
Preferably, in order to make the pointer, towards the direction of centrifugal force, improve the pointer when with the bit
Indicating effect, be movably connected between the pointer and the sliding block.
Preferably, in order to enable second convex block to promote the slide block movement and the fixed sliding block, described the
In close connection between two convex blocks and the sliding block.
Preferably, in order to enable the connector to be accurately connected with clamping device, the connector four sides is rectangular
Shape.
The beneficial effects of the utility model are:By drill bit internal set helicla flute can by drill bit produce waste material with
The rotation of drill bit is discharged from drilling, by setting pointer to mark the length that drill bit deeply drills in drill bit side, into
And staff is effectively prevented in drilling, go deep into the depth of construction material due to being unable to accurate judgement drill bit, cause the hole bored
Be not it is long be exactly it is too short, be unable to reach construction requirement all the time, to construction bring very big trouble.Slided by being set on stent
Block can adjust the height of pointer and then improve the use scope of product.The device has simple in structure, applied widely, punching
Accuracy is high, cheap, is especially suitable for the features such as punching beginner operates.

Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1 shown in -3, a kind of screw tap structure with helicla flute, including drill bit 1, the inside of drill bit 1 set spiral
Groove 2,1 side mounting and fixing support 3 of drill bit, 1 one end of drill bit set connector 4, and the inside of fixed frame 3 sets the first threaded hole 6, fixed
The first convex block 8 of the inside of frame 3 installation, 8 top mounting bracket 5 of the first convex block, the inside of stent 5 set sliding slot 13, and the top of sliding slot 13 is set
The second convex block 12, the inside of the second convex block 12 installation sliding block 9 are put, 9 one end of sliding block sets connecting hole 10, and the installation of the inside of connecting hole 10 refers to
