Description
Technical field
The utility model is related to hardware field, more particularly to cross hand screw.
Background technology
Screw, be using object inclined-plane circular rotating and frictional force physics and mathematical principle, by easy stages tightly
Gu the tool of implements parts is most common fastener, is widely used in all trades and professions.Screw head and screw rod are generally comprised,
And mostly metal material is made.
Screw generally comprises screw rod, head and fastening part, and screw rod is connected to head, and fastening part is opened in head.It is but existing
With the presence of the following shortcoming of screw of technology.On the one hand, it is necessary to fastening tool be used to drive screw that screw is screwed in workpiece
It is interior, inconvenient to use, second aspect, mechanical strength have it is to be strengthened, when being driven with fastening tool during screw is threaded in or out,
Since fastening tool generates the stress to screw rod to head active force, screw rod fracture is be easy to cause, is further resulted in using not
It is convenient.
Utility model content
It can directly be installed or removed with hand to solve the above problems, the utility model provides one kind, is easy to use, mechanical strong
Degree is high, cross hand screw not easy to break.
Technical solution is used by the utility model：Cross hand screw sets threaded screw rod including surface, connection
In the head of screw rod one end, the bucking ladder that screw rod deviates from head one end is connected to, the plastic cement hand outside head is set to and twists part, institute
The diameter for stating bucking ladder is laterally tapered into from close to the one of screw rod away from the side of screw rod；The plastic cement hand twists part in cross
Shape, plastic cement hand twist part center and offer groove for accommodating head；The plastic cement hand twists part and includes waterproof successively from inside to outside
Enhancement layer, plastic resilient layer and wear-resistant anti-skid layer；The screw diameter and head diameter and plastic cement hand twist the part longest edge length of side it
Than being 1:2:4.
Being further improved for above-mentioned technical proposal is integrally formed for, the screw thread, screw rod, head and bucking ladder, from interior
Include stainless steel ontology, through strengthening heat-treating profiled hardened layer in stainless steel body surface, being plated on hardened layer table to outer
The electroplated layer in face.
To being further improved as the plastic cement hand is twisted between the groove of part and head equipped with Nian Jie for above-mentioned technical proposal
Layer, and the plastic cement hand twists the edge of part through chamfered.
To being further improved as the thread cross-section is the triangle surrounded by three arc sidelines for above-mentioned technical proposal
Shape.
To being further improved as the thread form angle of the screw thread is 50 °~60 °, and the depth of thread is for above-mentioned technical proposal
