Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Provided by Fig. 1 to Fig. 7, the present invention includes the screwdriver handle 1 that there is cavity inside, accelerating gear storehouse 2 is equipped with in screwdriver handle 1 inside, accelerating gear storehouse 2 and screwdriver handle 1 are structure as a whole, the screwdriver rod 3 through accelerating gear storehouse is equipped with in the middle of screwdriver handle 1, the lower end of screwdriver rod 3 is connected with driver bit 4, accelerating gear storehouse 2 inner ring laminating is fixed with gear ring 5, the screwdriver rod 3 of gear ring 5 inside is set with master gear 6, connect through accelerating gear group 7 between master gear 6 and gear ring 5, accelerating gear group 7 is fixed on fixed mount 8, fixed mount 8 is fixed on the annular top cover lower end in accelerating gear storehouse 2, accelerating gear storehouse 2 inside lower end has shape dop groove 9 from all directions, connected by cone chamber between accelerating gear storehouse 2 and dop groove 9, screwdriver handle 1 inner lower edge is fixed with the large bearing 10 without inner ring be enclosed within screwdriver rod 3, screwdriver rod 3 below accelerating gear storehouse 2 is set with the dop 11 matched with dop groove 9, dop 11 and be set with anti-ejecting card 12 without on the screwdriver rod 3 between the large bearing of inner ring 10, screwdriver handle 1 internal fixtion above accelerating gear storehouse 2 has baffle plate 13, screwdriver rod 3 upper end be set be fixed on baffle plate 13 without the little bearing 14 of inner ring, screwdriver rod 3 between master gear 6 and baffle plate 13 is set with spring 15.
Described accelerating gear group 7 comprises the first governor gear 16 and the second governor gear 17, and gear ring 5 engages with the first governor gear 16, and the first governor gear 16 and the second governor gear 17 engage, and the second governor gear 17 and master gear 6 engage.
The first described governor gear 16 and the lower end of the second governor gear 17 central shaft are inlaid with ball 18, and when ball 18 can allow screwdriver rotate, frictional force is less.
The second described governor gear 17 has two, is relatively engaged on master gear 6 two ends respectively, and the second governor gear 17 two ends are engaged with first governor gear 16 respectively.
When the present invention uses, according to ordinary person use habit install or remove screw time, need pressing downwards, accelerating gear storehouse 2 is made to press to stressed screw direction with screwdriver handle 1, due to the effect of spring 15, screwdriver rod 3 can slide up and down, make accelerating gear storehouse 2 and master gear 6 in half disengaged position, screwdriver rod 3 top is by sliding in the cavity of baffle plate 13 upper end without the little bearing 14 of inner ring, now the dop groove 9 of lower end, gear accelerating gear storehouse 2 and the dop 11 of screwdriver rod 3 lower end tightly combine, thus realize screwdriver handle 1 and to rotate a circle the constant speed state that driver bit 4 also rotates a circle, after screw stressed alleviates, dop 11 is also departed from dop groove 9 by screwdriver rod 3 thereupon under spring 15 acts on, the anti-ejecting card 12 of screwdriver rod 3 upper chuck 11 lower end contact lower end without the large bearing 10 of inner ring, screwdriver rod 3 returns to previous status by half disengaged position, continue rotary screw handle of a knife 1, due to gear ring 5, first governor gear 16, second governor gear 17, master gear 6 engages, screwdriver handle 1 driver bit 4 that rotates a circle can be realized and rotate how week, be acceleration mode, due to the reason of ball 18, when screwdriver can be made to rotate, frictional force is less.
Structure of the present invention is simple, and input cost is low, saves plenty of time and labour, improves operating efficiency.
