Axostylus axostyle 2 is fixedly connected on the handle 1; The front end of axostylus axostyle 2 is provided with a deep trouth 22; This deep trouth 22 comprises two corresponding side walls; Leave the space that can supply screwdriver bit 5 rotations between the two side, on the two side, be respectively arranged with cinclides (for through hole 221), the effect of this through hole 221 is to carry out elasticity with the steel ball 51 of screwdriver bit 5 both sides to be connected.The middle part of axostylus axostyle 2 also is provided with guide groove 21, and this guide groove 21 is strip grooves, and the effect of this guide groove 21 is the helical pitches that guarantee that axle sleeve 4 moves forward and backward with respect to axostylus axostyle 2, and promptly axle sleeve 4 can only move in the length range of axostylus axostyle 2 guide grooves 21.Axostylus axostyle 2 is stepped, and in the present embodiment, axostylus axostyle 2 has two ladders; Axostylus axostyle 2 middle front parts are first ladder; Axostylus axostyle 2 rear portions are second ladder, and second ladder is square, and the phase I is circular; The length and width of second ladder are greater than the diameter of first ladder, and the diameter of axle of axostylus axostyle 2 rear ends (length of second ladder or wide) is greater than the diameter of axle of stating axostylus axostyle 2 front ends in other words.
Please refer to Fig. 2 A, Fig. 2 B and Fig. 2 C, sleeve pipe 3 is enclosed within the rearward end of axle sleeve 4, and sleeve pipe 3 is the tubulose of hollow also, and the length of sleeve pipe 3 is far smaller than the length of axle sleeve 4, and sleeve pipe 3 is fixedly connected with axle sleeve 4.In the utility model, be convexly equipped with a sloping piece 31 in the sleeve pipe 3, the front end of this sloping piece 31 is domatic, and this domatic gradient is from upper right slope under the left side, and this sloping piece 31 is corresponding to gain 41 positions of axle sleeve 4 and stretch in the gain 41.These sloping piece 31 follower's axle sleeves 4 can slide in the deep trouth 22 of axostylus axostyle 2 and stir the screwdriver bit 5 in the deep trouth 22.In the present embodiment, sloping piece 31 is made into integration with sleeve pipe 3.In the present embodiment, the upper end of axle sleeve 4 is provided with a fluting 32, and this fluting effect of 32 is space required when being convenient to satisfy screwdriver bit 5 and rotating.
The operation of some screwdriver bit 5 replaceable connections is following:
At first, promote axle sleeve 4, screwdriver bit one is stretched out in axle sleeve 4;
Secondly, firmly spur screwdriver bit one, at this moment, the steel ball 51 of screwdriver bit one both sides receive axostylus axostyle 2 cell wall pressure and spring is compressed, at this moment, the spring stress compression, steel ball 51 is pressed in the slotted eye of screwdriver bit one, at this moment, screwdriver bit one is pulled out from axostylus axostyle 2;
Then, screwdriver bit two is injected in the deep trouth 22 of axostylus axostyle 2, operate similar with a last step; Promptly enforce screwdriver bit two, the steel ball 51 of screwdriver bit two both sides receive axostylus axostyle 2 cell wall pressure and spring is compressed, at this moment; The spring stress compression, steel ball 51 is pressed in the slotted eye of screwdriver bit two; Continue to promote screwdriver bit two, when steel ball 51 arrived the through hole 221 of deep trouth 22 of axostylus axostyles 2, spring promoted steel ball 51 and outwards move this moment, and steel ball 51 is stuck in the slotted eye after being ejected in the slotted eye, has just accomplished screwdriver bit two and has operated with the flexible clamping of axostylus axostyle 2.
The replacing of other screwdriver bits 5 and the like, operate identical.
After more finishing changing screwdriver bit 5, carry out from the operation of moving head following to screwdriver bit 5:
Please refer to Fig. 3 A and Fig. 3 B, screwdriver bit 5 is at the state of not working, and screwdriver bit 5 is positioned at the deep trouth 22 of axostylus axostyle 2, and axostylus axostyle 2 is positioned at axle sleeve 4, and the 31 pairs of screwdriver bits 5 of sloping piece in the sleeve pipe 3 do not apply power;
With reference to figure 4A and Fig. 4 B, axle sleeve 4 is outwards released, and the sloping piece 31 on the sleeve pipe 3 is pushed out together thereupon and contacts with screwdriver bit 5 and screwdriver bit 5 is applied a pressure obliquely, and screwdriver bit 5 pressurizeds begin to rotate, and from the gain 41 of axle sleeve 4, rotate;
With reference to figure 5A and Fig. 5 B, continue to promote axle sleeve 4, after the guiding cushion block 42 in sleeve overwhelmed the other end of screwdriver bit 5, the pressure that screwdriver bit 5 receives guiding cushion block 42 was rotated further;
Continue to promote axle sleeve 4, be parallel to the gain 41 of axle sleeve 4 until screwdriver bit 5, at this moment, that has just accomplished screwdriver bit 5 once changes head.
More than a disclosed specific embodiment that is merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
