Description
Technical field
The utility model relates to installation and maintenance technical field of tools, refers in particular to a kind of novel screwdriver.
Background technology
Novel screwdriver is a kind of instrument conventional in wind power equipment installation process, but there is following problem in actual use: during the screw that 1, dismounting is tighter, because moment of torsion is too small or cutter head easily skids off from screw head, cause dismounting to be wasted time and energy; 2, the model due to screw is more, once-through operation often needs to carry various new screwdriver, although also there are some can the screwdriver of Quick changing cutter, the cutter head of this screwdriver relies on merely magnet adsorption effect to install, easily come off, bring unnecessary trouble to operator; 3, during work high above the ground, instrument may fall accidentally, not only makes troubles to construction, also there is the potential safety hazard that pendant thing is hurted sb.'s feelings.
Summary of the invention
The purpose of this utility model is to provide a kind of novel screwdriver, to solve the problem.
The purpose of this utility model realizes as follows: a kind of novel screwdriver, comprise handle of a knife, knife bar and cutter head, it is characterized in that: knife bar is arranged on handle of a knife, cutter head is arranged on knife bar end, one end away from knife bar on handle of a knife is provided with rotary sleeve, rotary sleeve is provided with safety collar, safety rope with snap close ties up on safety collar, handle of a knife both sides are hinged with boosting-rod respectively, the one end of knife bar being installed cutter head is processed with elongated slot, the bottom land of elongated slot is processed with blind hole, blind via bottom is provided with permanent magnet, the two side of elongated slot is equipped with slideway, the slide block be fixed on cutter head is arranged in slideway, ways-end is hatch frame, opening part is provided with projection.
The two ends of described cutter head are respectively " cross " type point of a knife and " word " type point of a knife.
The beneficial effects of the utility model are: the utility model novel structure, reasonable in design.The design of boosting-rod effectively can increase moment of torsion; When applying pressure to rotary sleeve, holder main body part still can rotate freely, and this makes applied pressure can try one's best large and can not affect rotation process, thus increases pressure to greatest extent, reduces the situation that cutter head skids off; Design with projection on the slideway of cutter head installation place on knife bar, can convert cutter head easily and cutter head can not come off after installing; The design of safety rope can effectively prevent instrument from falling, and relieves potential safety hazard.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model cutter head place structure enlarged diagram.
detailed description of the invention:
With reference to each figure, a kind of novel screwdriver, comprise handle of a knife 4, knife bar 2 and cutter head 1, it is characterized in that: knife bar 2 is arranged on handle of a knife 4, cutter head 1 is arranged on knife bar 2 end, handle of a knife 4 is provided with rotary sleeve 5 away from one end of knife bar 2, rotary sleeve 5 is provided with safety collar, safety rope with snap close 6 ties up on safety collar, handle of a knife 4 both sides are hinged with boosting-rod 3 respectively, the one end of knife bar 2 being installed cutter head 1 is processed with elongated slot, the bottom land of elongated slot is processed with blind hole, blind via bottom is provided with permanent magnet 10, the two side of elongated slot is equipped with slideway 8, the slide block 9 be fixed on cutter head 1 is arranged in slideway 8, slideway 8 end is hatch frame, opening part is provided with protruding 7.The two ends of described cutter head 1 are respectively " cross " type point of a knife and " word " type point of a knife.
The utility model novel structure, reasonable in design.The design of boosting-rod 3 effectively can increase moment of torsion; When applying pressure to rotary sleeve 5, handle of a knife 4 main part still can rotate freely, and this makes applied pressure can try one's best large and can not affect rotation process, thus can increase pressure to greatest extent, reduces the situation that cutter head 1 skids off from screw head groove; Slide block 9 is slided to the openend of slideway 8, the part being in the cutter head 1 in blind hole also shifts out from blind hole, now cutter head 1 is revolved turnback around slide block 9, and again insert in blind hole, just upper " cross " type point of a knife of cutter head 1 and the conversion of " word " type point of a knife can be completed, slideway with projection both can realize the disassembling, assembling and replacing of cutter head, can ensure that again cutter head can not come off after installing; Snap close on safety rope is buckled in the object near operating space or the place such as operator's clothes or waistband, can effectively prevents instrument from falling, relieve potential safety hazard.
