Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of socket cap axial screw as shown in Figure 1, including the axle sleeve 2 and screw body 1 being detachably connected, therefore is worked as
After thread damage on screw body 1, screw body 1 is replaced, reduces cost.
As shown in Figure 2 and Figure 3, screw body 1 is outer-hexagonal bolts, and axle sleeve 2 includes the big disk 21 and roundlet of coaxial arrangement
Column 22,21 diameter of big disk are greater than small column 22.Big disk 21 is provided with the counter sink 3 being caught in for 1 head of screw body, countersunk head
Hole 3 is communicated with the mistake nail hole 4 passed through for 1 bar portion of screw body.1 head of screw body be it is hexagonal and matched with counter sink 3,
Therefore axle sleeve 2 can not be rotated relative to screw body 1, and then avoid the generation of abrasion.The depth of counter sink 3 is greater than screw body 1
The thickness on head, counter sink 3 still has part exposing after 1 head of screw body is caught in counter sink 3, therefore die nut can be caught in
Wherein and axle sleeve 2 is driven to rotate, and then screw body 1 is driven to rotate, it is time saving and energy saving without slotting on screw body 1.
As shown in Figure 1 and Figure 2, big disk 21 is provided with fixed part 5 away from the side of small column 22, fixed part 5 include with greatly
The fixed disk 51 that disk 21 is close to and diameter is equal, the side of fixed disk 51 towards counter sink 3, which is fixedly connected with, is caught in counter sink 3
Locating piece 52, locating piece 52 is in just hexagonal.It is provided with and is close to 3 side wall of counter sink and flexible on the outside of locating piece 52
Locating piece 52 is caught in counter sink 3 until fixed disk 51 and big disk 21 are close to by dead ring 6, and screw body 1 is just by fixed disk
51 limit and be difficult to separate with axle sleeve 2, both avoid accidental separation and the trouble that needs to find, while avoiding twisting screw sheet
Manpower is needed to pinch the trouble of big disk 21 when body 1.The annular groove 521 being caught in for dead ring 6 is provided on the outside of locating piece 52, because
This dead ring 6 can be removed from locating piece 52, be replaced convenient for the dead ring 6 after aging.Fixed part 5 is away from axle sleeve 2
Side is provided with plum blossom trough 7, using interior double offset ring spanner, fixed disk 51, and then rotary axle box 2 can be rotated, to drive screw
Ontology 1 rotates.
As shown in Figure 2 and Figure 3, fixed disk 51 and axle sleeve 2 all have magnetism, so that mutually inhaling between fixed disk 51 and axle sleeve 2
Draw, therefore fixed part 5 is not easy to separate with axle sleeve 2, guarantees the effect of fixing screws ontology 1.The depth of counter sink 3 is equal to positioning
The thickness of block 52 adds the thickness on 1 head of screw body, therefore 1 head of screw body does not have a movable space, screw body 1 into
And can not be mobile relative to axle sleeve 2, and then avoid the generation of abrasion.3 opening of counter sink is provided with guidance chamfering 8, is convenient for screw
1 head of ontology is caught in counter sink 3.
The course of work:
1 bar portion of screw body was first passed through into nail hole 4 until its head is caught in counter sink 3, then locating piece 52 is caught in it is heavy
Head bore 3 is until fixed disk 51 is close to big disk 21, and just completion is installed.
After interior double offset ring spanner is caught in plum blossom trough 7, twists and fixed disk 51 is driven to rotate, locating piece 52 and then drive axle sleeve 2
Rotation, so that screw body 1 rotates.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
