Description
Affiliated technical field
The utility model relates to a kind of life common tool, particularly a kind of screwdriver with plurality of specifications driver bit.
Background technology
In the daily life, must use the screwdriver of all size, frequently change screwdriver and bother very much for the screw of the various models of installation or removal.People have designed " bull screwdriver " for this reason, they are that multiple dismountable driver bit is placed in certain specific driver bit box mostly, changing corresponding driver bit during use gets final product, as the patent No. is that the utility model patent of ZL200920021382.0 discloses a kind of " bull screwdriver ", and its design is that the driver bit with multiple model is placed in the driver bit box that is connected with handle end.And for example the patent No. is that the utility model patent of ZL200720112927.X discloses a kind of " a kind of combined screwdriver ", and its technical scheme is that handle and instrument cases are combined, and the driver bit of plurality of specifications is placed in the instrument cases.The overall structure that driver bit box that above patent is used or instrument cases have influenced screwdriver increases the volume of screwdriver, uses and carry inconvenience.
Summary of the invention
In order to overcome the defective that bull screwdriver volume is big, be inconvenient to carry, the utility model provides a kind of novel bull screwdriver, and this screwdriver is arranged in the end to end bunchiness of the driver bit of all size in the cavity of screwdriver rod and handle.When changing driver bit, the driver bit of screwdriver rod front end is extracted the tail end that inserts handle, release next driver bit simultaneously, can use up to releasing suitable driver bit.
The technical scheme that its technical problem that solves the utility model adopts is: the handle of screwdriver is threaded by upper handle and lower handle and forms, screwdriver rod is fixedlyed connected with lower handle, the end to end bunchiness of the driver bit of plurality of specifications is arranged in the cavity of screwdriver rod and handle, and driver bit can be moved in cavity by thrust.Be provided with spring and wedge-shaped catch between upper handle and lower handle, the tail end that wedge-shaped catch can prop up driver bit is when preventing the driver bit pressurized in the withdrawal cavity.Be provided with dop at the front end of screwdriver rod and be threaded with screwdriver rod, dop can provide driver bit effectively constraint to prevent that driver bit from coming off in use.The cross section of driver bit base and the cross section of cavity matches and for regular hexagon, rotate in use to prevent driver bit.The base of described driver bit is provided with container cavity, and the front end of back one joint driver bit can insert in the container cavity of last joint driver bit, and the effect of container cavity is the driver bit that holds more specifications in the cavity of finite length.
The beneficial effects of the utility model are that the end to end bunchiness of the driver bit of plurality of specifications is arranged in the cavity, has dwindled taking up room of driver bit, and is more convenient when changing driver bit.
