Abstract

The utility model discloses a convenient screw, which consists of a hexagonal screw head and a screw rod; the top of the hexagonal screw head is provided with a cross groove, a groove with a shape of Chinese character 'yi' is arranged at the center of the cross groove. Compared the utility model and present technology, not only various wrenches, a cross screwdriver in hands but also a screwdriver with a shape of Chinese character 'yi' in hands can all make action conveniently to the screw, the screw can be tightened or be loosened.

Description

A kind of screw that makes things convenient for

Technical field

The utility model relates to mechanical field, relates in particular to a kind of link, particularly a kind of screw that makes things convenient for.

Background technique

In the prior art; often adopt screw to fix the connection object, but because when in use, people realize that through regular meeting the screw-driver that revolving in the hand has is an in-line; and screw is criss-cross; or single spanner, if can put up with use, can produce serious damage to screw; the life-span of screw is reduced; perhaps screw-driver is criss-cross, and screw is an in-line, can't unclamp screw at all like this.

Summary of the invention

Technical problem to be solved in the utility model is, because people often adopt screw to fix the connection object, but screw of the prior art is except criss-cross, it is exactly in-line, people's work and production have been brought easily simultaneously, some worries have also been come, the utility model is for solving the above-mentioned technical problem in the prior art, the solution that is adopted provides a kind of screw that makes things convenient for, constitute by hex screw head and screw rod, the top of described hex screw head is provided with the cross groove, also be provided with an in-line groove in the centre of described cross groove, further, described in-line groove is through the cross position of intersecting point of described cross groove.

The utility model and prior art contrast, be applicable to the multiple tool mounting or dismounting of revolving, and strengthened the mechanical strength of screw, and be difficult for twisting bald, skid, no matter you have Philips screwdriver or Flathead screwdriver on hand, can work to screw easily, perhaps tighten, perhaps unclamp, and described screw head is hexagonal prism structure, can also utilize the spanner rotation.

Description of drawings

Fig. 1 is a kind of structural representation that makes things convenient for screw of the utility model.

A kind of structural representation that makes things convenient for the screw head of screw of Fig. 2 the utility model.

Embodiment

As shown in Figure 1 and Figure 2, a kind of screw that makes things convenient for of the utility model, constitute by hex screw head 1 and screw rod 2, the top of described hex screw head 1 is provided with cross groove 3, also be provided with an in-line groove 4 in the centre of described cross groove 3, further, described in-line groove 4 is through the cross position of intersecting point of described cross groove 3.

The utility model and prior art contrast, and no matter various spanners, Philips screwdriver are arranged on hand still is that Flathead screwdriver etc. revolves tool, can easily screw be worked, and perhaps tightens, and perhaps unclamps.

Claims (2)

1. one kind makes things convenient for screw, is made of hex screw head and screw rod, it is characterized in that: the top of described hex screw head is provided with the cross groove, also is provided with an in-line groove in the centre of described cross groove.

2. a kind of screw that makes things convenient for as claimed in claim 1 is characterized in that: described in-line groove is through the cross position of intersecting point of described cross groove.
