The bit member 3 is composed of a neck portion of the member and a gripping member 4 provided with a connecting projection having the same shape. In order to connect the storage recesses at the base of the bit member 2 in a crowned manner, the bit member becomes a single rod shape,
One driver is formed as a whole together with the handle member.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a driver that can selectively use various kinds of bits.

[0002]

[Prior Art]

 It is very convenient if one driver is equipped with various types of driver bits and an appropriate driver bit can be selected and used as needed. Therefore, various types of drivers have been proposed in the past, but basically they are roughly classified into two. That is, a type in which a plurality of bits are stored inside the handle, and one of them is selectively taken out and attached to the handle (Sukeko 57-192244, Sakukai 55-169373, 59-59). No. 50674), and different action parts (for plus screw and minus screw) are provided at both ends of one bit, and when attaching to the handle part, the front and rear parts are interchanged (Japanese Patent Laid-Open No. 63-74574, No. 55-11888) is known.

[0003]

[Problems to be solved by the device]

 The type in which multiple bits are stored inside the handle has a complicated structure and is complicated to manufacture, and the single bit type is convenient because there are few types of bits. Lack. Therefore, the present invention aims to provide a driver having a simple structure and provided with various kinds of bits.

[0004]

[Means for Solving the Problems]

 The driver according to the present invention comprises a base having a non-circular cross-section having a neck and a working recess such as a screwdriver connected to the tip of the neck, and the bottom having a housing recess for accommodating the working part and the neck. It is characterized by comprising a plurality of bit members connected to the base of the neck portion and a handle member provided with a connecting protrusion having the same shape as the neck portion of the bit member.

[0005]

[Action]

 The bit member is to be capped and connected to the connecting projection and to be connected to the working portion and the neck of the bit member that are sequentially mounted with the accommodating recesses of the bases of other bit members. It becomes a rod shape, and one driver is formed as a whole together with the handle member. Therefore, by separating the bit at any position and exposing the bit action part in the form of use, or attaching the bit member having the action part to use to the tip, it can be used as a driver for the action part. It is a thing.

[0006]

【Example】

 Next, an embodiment of the present invention will be described. The screwdriver according to the present invention comprises a plurality of bit members 1, 2, 3 and a handle member 4, and the bit members 1, 2, 3 respectively have an operating portion 11, 21, 31, a neck portion 12, 22, 32, and a base portion. 13, 23, 33 and storage recesses 14, 24, 34, and the neck, base and storage recess all have the same shape. The acting portion 11 is a plus driver, the acting portion 21 is a minus driver, and the acting portion 31 is a wood screw body. The necks 12, 22, 32 have a non-circular shape with a hexagonal shape or a quadrangle in cross section. The action parts 11, 21, 31 are connected to the tip side, and the bases 13, 23, 33 are connected to the base side. ing. Further, storage recesses 14, 24, 34 are provided on the bottom surfaces of the bases 13, 23, 33. The size is such that it can be stored, and the shape fits tightly with the neck portions 12, 22, 32. The grip handle member 4 comprises a handle body 41 and a connecting protrusion 42, and the connecting protrusion 41 has a cross section having the same shape as the neck portions 12, 22, 32.

When the connecting projection 42 of the plate member 4 and the storage recess 14 of the bit member 1 are tightly fitted and connected together, the bit member 2 can be used as a normal Phillips screwdriver, and the bit member 2 is replaced by the plate member 4 instead of the bit member 1. It can be used as a normal minor screwdriver when the neck portion 11 of the bit member 1 and the accommodating recess 24 of the bit member 2 are tightly connected to each other while the bit member 1 is attached. By mounting the bit member 1, 2 or 3 on the handle member 4 with the operating portion of the bit member 1 or 2 exposed, the driver can be used as a desired type of driver. An appropriate action portion 43 may be formed so as to project from the connecting projection 42 of the handle member 4, or the handle member may be hollow to accommodate an extra bit member.

[0008]

[Effect of the device]

 As described above, the present invention is composed of a plurality of bit members and one handle member, and the plurality of bit members can be connected to one another and can be attached to the handle member, so that any bit member can be exposed at the tip. Thus, it is possible to easily obtain a driver having a desired action portion, and further, it has an advantage that its structure is simple and manufacturing is easy.
