Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of plastic cap to be difficult to screw
The hands the turn of the screw of bar.
For achieving the above object, this utility model provides following technical scheme: a kind of hands the turn of the screw, including plastic cap and
Lead screw, described lead screw end is provided with the anti-delinking part being embedded in plastic cap, and described anti-delinking part is radially provided with some projections
Fixed block, forms anticreep groove between adjacent described fixed block.
Anti-delinking part is embedded in plastic cap, and the contact area between plastic cap and lead screw increases, and can disperse plastic cap and spiral shell
Active force between screw mandrel, prevents lead screw from rupturing；Fixed block radially extends in end, anti-delinking part, with plastic cap compact siro spinning technology, keeps away
Exempt from plastic cap loosening, to plastic cap limited location effect on lead screw direction of principal axis；Anticreep groove abuts with plastic cap, at plastic cap
Lead screw is driven to rotate during rotation, it is to avoid lead screw is skidded in plastic cap.
This utility model is further arranged to: described fixed block is uniform along the circumference of anti-delinking part.
When fixed block plays position-limiting action, fixed block has uniform pressure to plastic cap, it is to avoid unilateral pressure is excessive causes
The damage of plastic cap.
This utility model is further arranged to: described anticreep groove be shaped as circular arc.
Lead screw rotate time, the structure of circular arc can disperse the plastic cap pressure to fixed block sidewall, it is to avoid fixed block with
The junction fracture of anti-delinking part.
This utility model is further arranged to: the outer surface of described lead screw is provided with projection.
Projection strengthens the structural strength of lead screw, and when preventing plastic cap from rotating, plastic cap breaks with the junction of lead screw
Split.Increase the contact area of lead screw and plastic cap, prevent lead screw from skidding in plastic cap further.
This utility model is further arranged to: described lead screw end is provided with the guide pad of taper.
Lead screw is inserted after installing hole rotates and is completed to fix, and guide pad helps user faster lead screw to be inserted installation
Hole, decreases the set-up time.
This utility model is further arranged to: the side surface of described plastic cap is provided with and some divides the most at equal intervals
The non-slipping block of cloth.
Non-slipping block adds the contact area between user and plastic cap, it is to avoid user skids when rotating plastic cap,
Facilitate the user grasping to plastic cap, lighter when rotating.
This utility model is further arranged to: the side surface of described plastic cap is provided with some bars for increasing frictional force
Stricture of vagina.
Striped adds the frictional force on plastic cap surface, further facilitates user and rotates plastic cap, can easily
Install or remove hands the turn of the screw.
This utility model is further arranged to: the outer surface of described plastic cap is provided with cross recess.
User rotates after plastic cap is fixed, and can carry out tightening by screwdriver opponent's the turn of the screw fixing, screw
Bar is connected tightr with installing hole.
This utility model is further arranged to: the quantity of described fixed block is 3.
Three fixed blocks form firm three-legged structure, and lead screw is difficult to abjection, and the angle of the anticreep groove of formation is moderate, makes
Lead screw both will not be skidded in plastic cap, and anti-delinking part is also not easy fracture.
By using technique scheme, this utility model has the advantages that lead screw is difficult in use
Skidding in plastic cap, user operation is light, hands the turn of the screw fixation.
Compared with prior art, the utility model has the advantage of: plastic cap is completely embedded with lead screw, be difficult to abjection.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of hands the turn of the screw, such as Fig. 1, including plastic cap 1 and the lead screw 2 of metal of plastics.Lead screw 2 machines
After, by the way of injection, plastic cap 1 is processed in lead screw 2.
Such as Fig. 2, the end of lead screw 2 is provided with the guide pad 6 of taper, and installation position is equipped with installing hole, needs spiral shell during installation
Screw mandrel 2 inserts installing hole, and the conical head of guide pad 6 has guide effect, makes lead screw 2 insert installing hole more quickly.Screw
The middle part of bar 2 is provided with screw thread, and screw thread seals with installing hole and coordinates.The head end of lead screw 2 is provided with anti-delinking part 3, the appearance of lead screw 2
Face is provided with four protruding projections 5, adds the interaction force between plastic cap 1 and lead screw 2, it is to avoid lead screw 2 is being moulded
Skidding in stub bar 1, projection 5 also strengthens the structural strength of lead screw 2 and plastic cap 1 junction simultaneously, is avoided that lead screw 2 exists
Rotation is ruptured.
The end of anti-delinking part 3 is radially provided with three protruding fixed blocks 4, and as shown in figures 1 and 3, fixed block 4 is in anti-delinking part
The circumference of 3 is uniform, and fixed block 4 adds the contact area of lead screw 2 and plastic cap 1, and lead screw 2 is connected tighter with plastic cap 1
Close.Between adjacent two fixed blocks 4 formed anticreep groove 10, anticreep groove 10 be shaped as circular arc.When plastic cap 1 rotates, drive
Lead screw 2, anticreep groove 10 is connected on plastic cap 1, it is to avoid lead screw 2 is skidded in plastic cap 1.
Such as Fig. 4, the side surface of plastic cap 1 is provided with some non-slipping blocks 7 being along the circumferential direction spacedly distributed, the most also sets
There are some stripeds 8 for increasing frictional force.Non-slipping block 7 and striped 8 both increase the frictional force on plastic cap 1 surface, user
Rotate plastic cap 1 time more laborsaving.
Such as Fig. 1, the outer surface of plastic cap 1 is provided with cross recess 9, and user can use the screw coordinated with cross recess 9
Cutter opponent's the turn of the screw is tightened, it is also possible to is directly twisted by hands and is fixed, reaches the multifunction of hands the turn of the screw.
