Abstract
The utility model discloses a head structure of a screw driver for rotating a hand-rotated screw, which comprises a driver shaft and a driver tip, wherein the driver tip is in a cylinder shape, the head part of the driver tip is provided with a nut fixing hole matched with the nut of the hand-rotated screw, the nut fixing hole is internally provided with a boss matched with a stressed groove of the top part of the nut of the hand-rotated screw, and the edge of the nut fixing hole is formed with a notch matched with the hand-rotated handle of the hand-rotated screw. Sine the head structure of the screw driver, which is operated by hand or power and is matched with the hand-rotated screw, is utilized for screwing or unscrewing the hand-rotated screw, the utility model replaces the traditional hand operation, improves the production efficiency of the product and ensures the hand-rotated screw to be rotated in place. At the same time, since the direction contact of the operator can be avoided, the utility model can avoid the potential safety hazard in the operation process.
Description
Technical field the utility model relates to a kind of screwdriver structure, relates in particular to a kind of driver bit structure that is used to rotate the hand screw type screw.
Background technology utility model patent 200920182819.9 " fixture that display bracket is connected with base " discloses a kind of fixing hand screw type screw that is used between production line upper bed-plate and the display bracket, as shown in Figure 1, the nut 31 of this hand screw type screw 3 is provided with hand-screw handle 33, owing to lack special-purpose driver bit structure, so generally be that the operator screws or unscrew the hand screw type screw by the hand-screw handle on the manual rotation hand screw type screw.Like this, the dismounting of screw will spend a large amount of man-hours, and production efficient is low, and manually rotation may exist screw to rotate the situation that can't put in place owing to the dynamics deficiency simultaneously.In addition, the operator's that frays easily in the process of manual rotary screw hand causes potential safety hazard.
The summary of the invention the purpose of this utility model provide a kind of convenient, fast, reliably rotate the driver bit structure of hand screw type screw.
For achieving the above object, the utility model comprises cutter shaft and point of a knife, described point of a knife is cylindrical, the head of point of a knife is provided with the fixed by nut hole of matching with the nut of hand screw type screw, inside, described fixed by nut hole is provided with the projection that matches with the stressed groove at the nut top of hand screw type screw, and described fixed by nut bore edges offers the breach that matches with the hand-screw handle of hand screw type screw.When rotation hand screw type screw, nut is chimeric goes in the fixed by nut hole of cutter head structure, stressed groove on the nut matches with the fixed by nut hole protrusions of cutter head structure simultaneously, hand-screw handle on the nut is received in the breach in fixed by nut hole of cutter head structure, can guarantee that like this cooperation of cutter head structure and hand screw type screw puts in place, by manual or electronic this cutter head structure of rotation, can be fast, reliably the hand screw type screw is rotated in place.
In sum, the utility model compared with prior art, the utility model utilization driver bit structure manual or that electric operating matches with the hand screw type screw screws or unscrews the hand screw type screw, replaced traditional manual operation, not only improved production efficiency of products, and guaranteed that the hand screw type screw is rotated in place.Simultaneously, owing to avoided operator's direct contact, avoided the potential safety hazard in the operating process.
Description of drawings is described in further detail the utility model below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of hand-screw screw in the prior art;
Fig. 2 is a schematic cross-section of the present utility model;
Fig. 3 is the head vertical view of the utility model point of a knife.
The specific embodiment such as Fig. 2, shown in Figure 3, the utility model comprises cutter shaft 1 and point of a knife 2, described point of a knife 2 is cylindrical, the head 21 of point of a knife 2 is provided with the fixed by nut hole 22 of matching with the nut 31 of hand screw type screw 3,22 inside, described fixed by nut hole are provided with the projection 23 that matches with the stressed groove 32 at nut 31 tops of hand screw type screw 3, and 22 edges, described fixed by nut hole offer the breach 24 that matches with the hand-screw handle 33 of hand screw type screw 3.
When rotation hand screw type screw 3, nut 31 is chimeric goes in the fixed by nut hole 22 of cutter head structure, stressed groove 32 on the nut 31 matches with fixed by nut hole 22 protrusions 23 of cutter head structure simultaneously, hand-screw handle 33 on the nut 31 is received in the breach 24 in fixed by nut hole 22 of cutter head structure, by manual or power operated rotary knife axle 1, make point of a knife 2 follow cutter shaft 1 and rotate, further drive hand screw type screw 3 and rotate and screwed or unscrew.
