The utility model is further set to: described strut and rotation section are wholely set, and the quantity of described strut is even number and is circle distribution on rotation section with the center of circle of rotation section.
By adopting technique scheme, strut slightly protrudes the side surface of rotation section, pull rotation section for user, strut circle distribution on the side of rotation section and each strut be all positioned in same level, make stressed more concentrated on rotation section, also person easy to use rotates that install rotation section or knockout screw.
The utility model is further set to: described rotation section is provided with stiffening rib.
By adopting technique scheme, on the side of rotation section, be to be provided with stiffening rib between adjacent two struts, stiffening rib plays the effect of the structural strength that strengthens rotation section, extends the working life of screw.
The utility model is further set to: the quantity of described strut is that two and described strut are evenly distributed on side, rotation section.
By adopting technique scheme, the quantity of the utility model strut is preferably two, the even circle distribution of strut is on rotation section, user comes manpower rotation rotation section by strut, user can singlehanded be against finger on strut or hold strut with two simultaneously and rotate rotation section, drive screw to rotate together, screw is not easy to wear.
The utlity model has following advantage: set up main tooth by the head outer surface at screw, and be arranged with the rotating component being meshed with head outward at head, can repeatedly dismantle and not easy to wear by rotating rotating component, greatly extend the working life of screw.
Brief description of the drawings
Fig. 1 is the utility model screw embodiment one structural representation;
Fig. 2 is the utility model screw embodiment two structural representation.
In figure: 1, head; 2, main tooth; 3, rotating component; 31, rotation section; 32, secondary tooth; 4, strut; 5, through hole; 6, fixing rod; 7, sliding bar; 8, stiffening rib.
Embodiment
Shown in Fig. 2, screw, comprise discoid head 1, the side of described head 1 is arranged with main tooth 2, described head 1 is arranged with the rotating component 3 being meshed with head 1, described rotating component 3 comprises and is set in rotation section on head 1 and in the form of a ring 31 and is arranged on the secondary tooth 32 engaging on 31 inwalls of rotation section and with main tooth 2, and relatively secondary tooth 32 opposite sides in described rotation section 31 are provided with strut 4.
By adopting technique scheme, in the time that needs are screwed object, rotating component 3 is installed to the head 1 of screw, main tooth 2 engages with secondary tooth 32, rotating component 3 links with head 1, user's rotary supporting rod 4, and strut 4 drives rotating component 3 to rotate, thereby the secondary tooth 32 on rotating component 3 drives main tooth 2 to move and drives screw turns, and screw is fixedly treated mounting article; In like manner, in the time of needs knockout screw, rotary support bar 4, rotating component 3 rotates, drive head 1 to rotate together until screw screws out, can repeatedly dismantle screw, and main tooth 2 engages with secondary tooth 32, both area of contact are large, and screw is not easy to wear, greatly extended the working life of screw.
