Accompanying drawing explanation

Fig. 1 is the profile of the screwdriver head of a kind of electric screw driver of the utility model.

Wherein: 1-screwdriver head; 2-sleeve; Hold-down bolt under 3-; 4-drill bit; The upper hold-down bolt of 5-.

Detailed description of the invention

As shown in Figure 1, the utility model discloses a kind of screwdriver head of electric screw driver, comprise: screwdriver head 1, sleeve 2, lower hold-down bolt 3, drill bit 4, upper hold-down bolt 5, the upper end of described screwdriver head 1 is deep into sleeve 2 inside, the described left and right sides, sleeve 2 lower end is the lower hold-down bolt 3 of precession one respectively, and the screw rod precession sleeve 2 of lower hold-down bolt 3 is inner and be pressed in sleeve 2 by the upper end of screwdriver head 1, the lower end of described drill bit 4 is deep into sleeve 2 inside, the described left and right sides, sleeve 2 upper end is the upper hold-down bolt 5 of precession one respectively, the screw rod precession sleeve 2 of described upper hold-down bolt 5 is inner and be pressed in sleeve 2 lower end of drill bit 4.

The utility model implements like this: when needs are holed, directly the lower end of screwdriver head 1 is installed on electric screw driver, the rotating band moving sleeve 2 of screwdriver head 1 rotates, the rotation of sleeve 2 then drives drill bit 4 to rotate and punches, when needs locking or pine move back screw, the tight bolt 3 of rotating down pressing is only needed to unclamp screwdriver head 1, screwdriver head 1 is taken out in sleeve 2, can carry out like this locking or pine moves back screw, use more convenient, and a kind of equipment can realize two kinds of functions simultaneously, more convenient, and cost also reduces greatly.

Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model; Therefore, although this description has been described in detail the utility model with reference to each above-mentioned embodiment, those of ordinary skill in the art should be appreciated that and still can modify to the utility model or equivalent replacement; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
