Embodiment Construction

[0082] The screwdriver shown here comprises a main housing 10 which receives and supports a holder 11 . The holder 11 has a plurality of socket openings 12 parallel to a longitudinal axis 13 of the cylindrical holder 11 . The clip has two end faces 14 and 15 at right angles to the axis 13 , which allow the clip to slide inside a receptacle 16 of the housing 10 .

[0083] At the front of the housing 10 there is a tube 17 connected to the housing and rotatable therewith. The tube 17 has a hexagonal inner surface 18 along which a tool head 19 can slide from the clamp to a forward presentation position 20 at the forward end 21 of the tube 17, the hexagonal inner surface 18 in contact with the tool. The outer surfaces of the head are matched so that when the housing rotates and rotates the pipe 17 connected to the housing, this matching can drive the tool head to rotate with the pipe. The tube 17 is arranged around the axis 22 of the housing. The housing has a body part 23 which...

Abstract

A screwdriver for containing and providing implement heads, comprising a casing, which has a extension tube extending to the forward presenting end along the axial cord. The implement head presents for using on the forward presenting end. The casing is equipped with a rotable storage holder for retaining and depositing a plurality of implement heads, which can be manually connected with a exposed latus to rotate round the second axial cord parallel with the pipe. A plunger piston is carried by a terminal cap, which has a hexagon cannula. A flat magnetic implement heads feeding plane is provided on the leading end of the cannula, and a corresponding part of the casing is sliding fit accommodated. The holder can be removed by pressing a push-button which is located on the opposed face of the casing. The holder is equipped with a magnet for keeping implement heads in position. The plunger piston is restricted by a friction head to prevent free moving, and the friction head is pressed on side of the plunger piston.

Description

technical field [0001] The invention relates to a screwdriver having a plurality of bits interchangeable within the screwdriver. Background technique [0002] Tools like screwdrivers or the like generally include a handle having a portion extending forward for turning a single type of screw. Some screwdrivers are adapted to allow the operator to change the tool head for use with different types of screws so that only one screwdriver is required instead of many different types of drivers. These variable screwdrivers typically require the operator to manually remove the bit from the screwdriver and replace it with a new one, creating the possibility that the bit may be lost or misplaced. Many times the tool head remains in the handle which can be opened to allow it to be removed. [0003] The screwdriver of the present invention can be used to screw into drive tool bits, sockets, drill bits or other tool bits that have different operations and need to be changed within the s...
