Abstract
The utility model discloses a screw driver head with an improved structure, which mainly focuses on the structure improvement of edge-driving part in the front end of the anti-skid screw driver. The utility model increasing the friction force and the slip-resistance, full plays the excellent using efficiency. The utility model, in the aspect of structure improvement, mainly adds limit slip granules at a section of the edge driving part at the front end of the screw driver. The limited slip granules are distributed at the edge driving part of the screw driver in an irregular way. Therefore the friction force and the limit slip effect are strengthened obviously and the shedding phenomenon is prevented. The utility model can full play the using efficiency.
Description
Technical field
The utility model relates to a kind of screwdriver head, particularly relates to a kind of screwdriver head that plays the architecture advances of blade at anti-skidding screwdriver head front end.
Background technology
Be illustrated in figure 1 as the three-dimensional structure diagram of generally commonly using screwdriver head, this screwdriver head 10 is general the most frequently used and modal, it can be placed on the front end of instrument such as screwdriver rod and do the usefulness of pine, lock screw, and the blade 101 that rises of the screwdriver head 10 that this is commonly used is the design of level and smooth formula, the phenomenon that therefore slip can easily be arranged in rotating in the use, CONTACT WITH FRICTION power between itself and screw is also lower, and then influences it and manipulate effect; Then be a kind of improved screwdriver head as shown in Figure 2,11 of this screwdriver heads are provided with cross-striated body 112 in blade 111 places, so as to when using rotation, having preferable frictional force and anti-slip effect, yet actual the use finds that upward the anti-slip effect that its band formula designing institute produces is limited in fact, and be unsatisfactory in the use; Have in addition at present and a kind ofly be sprayed on the design that screwdriver head plays blade with diamond dust, yet this kind designs not only processing time consuming and processing cost is also high, and it is attached to the mode of screwdriver head with spray, in use also is easy to generate the phenomenon that comes off, and then influences its effective utilization.
Summary of the invention
The purpose of this utility model is to improve above-mentionedly commonly uses product shortcoming in the use, thereby a kind of screwdriver head of architecture advances is provided.
For reaching this purpose, the utility model adopts following technical scheme: the blade one section system in the screwdriver head front end forms the anti-slip particles body, and this anti-slip particles body is laid in the blade that rises of screwdriver head with irregular mode.
The screwdriver head of the architecture advances made from above-mentioned design, not only can have excellent frictional force and anti-slip effect in the use, and since its anti-slip particles body and screwdriver head for being made into integration, can effectively prevent obscission, thereby can give full play to its excellent effective utilization in the use, and then promote the efficient in the operation.
Description of drawings
Fig. 1 is a stereogram of commonly using screwdriver head;
Fig. 2 commonly uses the stereogram of screwdriver head for another;
Fig. 3 is the stereogram of screwdriver head of the present utility model.
The specific embodiment
Below cooperate the specific embodiment, the structural design features of screwdriver head of the present utility model is described further.
Be illustrated in figure 3 as the stereogram of screwdriver head of the present utility model, as shown in the figure, the utility model mainly is that the blade 201 one section systems in screwdriver head 20 front ends form anti-slip particles body 202 on structural design, this anti-slip particles body 202 is to be laid on the screwdriver rod with irregular mode, agreeing with when rotating with screw, can fully effectively promote its frictional force and anti-slip effect, operation is carried out more efficiently; And therefore this anti-slip particles body 202 and screwdriver head 20 can effectively prevent obscission for being made into integration, and have preferable service life, and integral body can be given full play to its excellent effective utilization.
