Description
【Technical field】
The utility model is related to fastener areas, especially a kind of novel screw.
【Background technology】
Screw screw is common in machinery, electric appliance and building etc., and general material is metal or plastic cement, cylindrical, surface
It carves irregular ditch and is known as screw thread Screw thread.The main function of screw is two objects of engagement, or fixes an object
The position of body.Screw usually can arbitrarily remove or again panelling without damaging its efficiency.The top diameter of general screw is larger, common
Have round, rectangular or regular hexagon, if top be regular hexagon, can use spanner rotate screw, if top be circle, top
Front also has rill, and corresponding screwdriver easy to use rotates screw.Most common rill has "-" type, cross and square
Shape, also there is other shapes, and the groove of existing screw usually device ailhead is easy to wear, causes screw to be not convenient to use, causes
Screw is scrapped, further, since screw does not have chip removal structure, is caused screw to shoot other objects relatively difficult, is affected screw
Service efficiency.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of novel screw, can be with a variety of
Mode is screwed or is taken out to screw, promotes convenience and versatility that screw uses, screw can be facilitated to shoot other
Chip removal is carried out when object, promotes the penetration rate of screw, promotes the service efficiency of screw, extends the service life of screw.
To achieve the above object, the utility model proposes a kind of novel screws, including ailhead, nail rod, tooth line and chip removal
Slot, the ailhead are located at the upper end of nail rod, and the outer surface of the nail rod is equipped with spiral helicine tooth line, is erected on the line body of the tooth line
It heads straight for being equipped with multiple chip spaces, the upper end of the ailhead offers square groove, and the bottom of the square groove is recessed equipped with cross
The depth of slot, the square groove is 2 millimeters, and the depth of the cross recess is 1 millimeter, the flute length of the cross recess
Less than the flute length of square groove.
Preferably, the ailhead, nail rod, tooth line design for integral type, the ailhead, nail rod central shaft be located at it is same
On vertical line.
Preferably, the depth of the chip space is identical with the height of tooth line, the chip space is located at the not homonymy of nail rod
Face is simultaneously located at same level height in around the opposite end of shape and neighbouring chip space, the total height of the chip space and
The height of nail rod is identical.
The beneficial effects of the utility model：The utility model on the top of ailhead by being equipped with square groove, rectangular recessed
Trench bottom is equipped with cross recess, is equipped with multiple chip spaces vertically on tooth line, and the depth of chip space is identical with the height of tooth line, row
The opposite end for the not ipsilateral and neighbouring chip space that bits slot is located at nail rod is located at same level height, can be with a variety of
Mode is screwed or is taken out to screw, and the versatility of screw is improved, can when screw is when piercing other objects
Facilitate chip removal to promote penetration rate, compared with prior art, can screw be screwed or be taken out in many ways, is promoted
The convenience and versatility that screw uses, can facilitate screw to carry out chip removal when shooting other objects, promote piercing for screw
Speed promotes the service efficiency of screw, extends the service life of screw.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
【Description of the drawings】
Fig. 1 is a kind of structural front view of novel screw of the utility model.
In figure：1- ailheads, 2- nail rods, 3- teeth line, 4- chip spaces.
Fig. 2 is a kind of structure top view of novel screw of the utility model.
In figure：1- ailheads, 11 square grooves, 12- cross recess.
【Specific implementation mode】
Refering to fig. 1, a kind of novel screw of the utility model, including ailhead 1, nail rod 2, tooth line 3 and chip space 4, the nail
First 1 is located at the upper end of nail rod 2, and the outer surface of the nail rod 2 is equipped with spiral helicine tooth line 3, is opened vertically on the line body of the tooth line 3
Equipped with multiple chip spaces 4, the ailhead 1, nail rod 2, tooth line 3 design for integral type, the ailhead 1, nail rod 2 central shaft be located at
On same vertical line, the upper end of the ailhead 1 offers square groove 11, and the bottom of the square groove 11 is equipped with cross recess
12, the depth of the square groove 11 is 2 millimeters, and the depth of the cross recess 12 is 1 millimeter, the cross recess
12 flute length is less than the flute length of square groove 11, and the depth of the chip space 4 is identical with the height of tooth line 3, and the chip space 4 is set
Nail rod 2 not ipsilateral and be located at same level height in the opposite end around shape and neighbouring chip space 4, it is described
The total height of chip space 4 is identical as the height of nail rod 2.
Utility model works process：
A kind of novel screw of the utility model during the work time, by offering square groove 11 on the top of ailhead 1,
Cross recess 12 is offered in the bottom of square groove 11, offers multiple chip spaces 4, the depth of chip space 4 vertically on tooth line 3
Degree is identical with the height of tooth line 3, and chip space 4 is located at the not ipsilateral of nail rod 2 and the opposite end of neighbouring chip space 4 position
It is identical as the height of nail rod 2 in the total height of same level height, chip space 4, it, can be with when screw needs are screwed or taken out
It is operated using different tools, improves the versatility of screw, when screw is when piercing other objects, can be facilitated
Chip removal is to promote penetration rate, compared with prior art, can screw be screwed or be taken out in many ways, and screw is promoted
