Description

Double-groove screwdriver head

Technical Field

The utility model relates to the technical field of batch heads, in particular to a double-groove batch head.

Background

The screwdriver bit is one of the necessary tools for most production enterprises, is an ideal efficient and quick-mounting tool, and is widely applied to the industries of aviation, automobiles, machines, electric appliances and the like. Has remarkable effect of improving labor productivity and reducing labor intensity of workers. At present, the applicable batch heads are different in machine structure, the installed batch heads are also different, the batch heads produced in domestic market cannot be used commonly with a daily version long tail groove machine and a American version short tail groove machine, and the batch heads are limited in use.

Disclosure of Invention

In view of the above, in order to solve the above problems, the present utility model provides a double-groove screwdriver bit, which has the following specific technical scheme:

the utility model provides a head is criticized to double tank, includes connecting portion and the head of an organic whole connection, open the bottom of connecting portion has two card to put the groove and be day version long tail groove and beautiful version short tail groove respectively.

Further, the clamping groove is of an annular arc groove structure.

Further, the distance between the center of the long tail groove of the daily edition and the head and the tail of the batch is 14.5mm, the distance between the center of the short tail groove of the American edition and the head and the tail of the batch is 9.5mm,

by adopting the technical scheme, the method has the following beneficial effects:

the utility model has two clamping grooves at the bottom of the connecting part, each clamping groove corresponds to machines of different types, and the two clamping grooves are arranged on the batch head and can be used for a daily version long tail groove machine and a American version short tail groove machine.

FIG. 2 is a schematic structural view of the connection between the chuck of the impactor and the screwdriver bit of the European and American version;

FIG. 3 is a schematic diagram of the connection between the screwdriver chuck and the screwdriver chuck of the impactor in the current edition and the state;

in the figure: 1-a day version long tail groove; 2-a American version short tail groove; 3-connecting part; 4-head.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

Example 1: as shown in the figure, the double-groove screwdriver head comprises a connecting part 3 and a head part 4 which are integrally connected, wherein two clamping grooves are respectively formed in the bottom of the connecting part 3 and are a day plate long tail groove 1 and a American plate short tail groove 2, and the clamping grooves are of an annular arc groove structure.

When the utility model is specifically used, the daily version long tail groove 1 of the batch head is matched with the daily version and national line impact screwdriver, the American version short tail groove 2 of the batch head is matched with the European and American version impact screwdriver, and one batch head can be applied to two versions of machines, so that the application range of products is increased.

As shown in fig. 2-3, two clamping grooves are formed in the bottom of the connecting part 3, each clamping groove corresponds to a machine of different types, and two clamping grooves are formed in the batch head and can be used for a long tail groove machine of a daily edition and a short tail groove machine of a American edition.

In the embodiment, the distance between the center of the long tail groove of the daily edition and the head and the tail of the batch is 14.5mm, the distance between the center of the short tail groove of the American edition and the head and the tail of the batch is 9.5mm,

the double clamping grooves of the screwdriver head can be suitable for impact screwdrivers of various types. The screwdriver can not be blocked by clamping beads caused by forcing the screwdriver head to squeeze into the chuck because the clamping groove of the screwdriver head is too close when in use if a day version or a national line screwdriver is used. The problem that the screwdriver head is easy to drop in use because the clamping beads of the screwdriver head clamping head cannot clamp the screwdriver head because the screwdriver head clamping groove is too far away if the screwdriver of European and American edition is used is solved.

While the basic principles and main features of the present utility model have been described above, it will be understood by those skilled in the art that the present utility model is not limited by the above-described embodiments, which are described in the foregoing description merely illustrate the principles of the present utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model as defined in the appended claims and their equivalents.

Claims
