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 inside has the screwdriver handle 1 of cavity, accelerating gear storehouse 2 is equipped with in screwdriver handle 1 inside, accelerating gear storehouse 2 is structure as a whole with screwdriver handle 1, in the middle of screwdriver handle 1, be equipped with the screwdriver rod 3 through accelerating gear storehouse, the lower end of screwdriver rod 3 is connected with driver bit 4, the 2 inner ring laminatings of accelerating gear storehouse are fixed with gear ring 5, on the screwdriver rod 3 of gear ring 5 inside, be set with master gear 6, between master gear 6 and gear ring 5, connect through accelerating gear group 7, 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 have shape dop groove 9 from all directions, between accelerating gear storehouse 2 and dop groove 9, connected by cone chamber, screwdriver handle 1 bottom, inner side is fixed with the large bearing 10 without inner ring being enclosed within on screwdriver rod 3, on the screwdriver rod 3 of 2 belows, accelerating gear storehouse, be set with the dop 11 matching with dop groove 9, dop 11 and without being set with anti-ejecting card 12 on the screwdriver rod 3 between the large bearing 10 of inner ring, in the screwdriver handle 1 of 2 tops, accelerating gear storehouse, be fixed with baffle plate 13, screwdriver rod 3 upper ends be set be fixed on baffle plate 13 without the little bearing 14 of inner ring, on screwdriver rod 3 between master gear 6 and baffle plate 13, be 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.

On the first described governor gear 16 and the lower end of the second governor gear 17 central shafts, be inlaid with ball 18, when ball 18 can allow screwdriver rotation, frictional force is less.

The second described governor gear 17 has two, is relatively engaged on respectively master gear 6 two ends, and the second governor gear 17 two ends are engaged with respectively first governor gear 16.

When the present invention uses, according to ordinary person's use habit when the installation or removal screw, need to press downwards, make accelerating gear storehouse 2 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 be half disengaged position, screwdriver rod 3 tops can be by sliding in the cavity of baffle plate 13 upper ends without the little bearing 14 of inner ring, the now tightly combination of dop 11 of the dop groove 9 of 2 lower ends, gear accelerating gear storehouse and screwdriver rod 3 lower ends, thereby realize the screwdriver handle 1 constant speed state that driver bit 4 also rotates a circle that rotates a circle, when after stressed the alleviating of screw, screwdriver rod 3 also departs from dop groove 9 by dop 11 thereupon under spring 15 effects, the anti-ejecting card 12 of screwdriver rod 3 upper chuck 11 lower ends 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, the first governor gear 16, the second governor gear 17, master gear 6 engages, can realize screwdriver handle 1 driver bit 4 that rotates a circle and how rotate week, be acceleration mode, due to the reason of ball 18, can make screwdriver rotation time, frictional force is less.
