Description

Multifunctional screw driver

Technical field

The utility model relates to screwdriver, specifically is a kind of multifunctional screw driver.

Background technology

It is removable the connection with screwdriver rod that existing multifunctional screw driver is generally driver bit, form different screwdrivers by changing driver bit, though this class multifunctional screw driver scope of application is wide, practical, but also there is following shortcoming: when changing driver bit, need look for the driver bit that changes the place to deposit, prior art to have a kind of be that driver bit is directly left in the groove on the handle, will influence the gripping sense of handle like this, and driver bit is easy to lose.

The utility model content

The technical problems to be solved in the utility model is, a kind of multifunctional screw driver that handle grip sense and driver bit are difficult for losing that do not influence is provided.

The technical solution of the utility model is, a kind of multifunctional screw driver with following structure is provided, and comprises the handle, screwdriver rod, the driver bit that are provided with inner chamber; It is characterized in that: it also comprises inner core, bonnet, spill spin block, the inner chamber of described inner core and handle is rotationally connected, the excircle of described inner core is provided with a plurality of axial notches, described driver bit is plugged in the groove, described handle also is provided with and the corresponding shaft orientation opening groove of a groove wherein, be covered with a radially elongated slot that allows spill spin block pass through after described, described bonnet is connected with handle is removable, and described spill spin block is connected with inner core.

After adopting above structure, the utility model compared with prior art, have the following advantages: because the excircle of described inner core is provided with a plurality of axial notches, described driver bit is plugged in the groove, promptly the driver bit that needs are changed is placed in the groove of inner core, when needs take out the driver bit that needs, earlier stir inner core by spill spin block, make the open slot on the driver bit alignment handle that needs, take out driver bit, the driver bit that changes is placed in the groove of inner core, so just do not influence the gripping sense of handle, and driver bit is provided in a side of handle inside, also is difficult for losing.

As improvement, described bonnet is threaded with removable being connected to of handle, makes things convenient for inner core to take out from the inner chamber of handle.
