Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric tool, and more particularly, to an electric tool for tightening screws, drilling holes, etc. by driving a chuck to which a driver pit, drill pit, etc. is attached using a motor.

Conventionally, this type of electric power tool has a power supply and battery housed in a single housing, and the housing has to be held in hand to tighten screws, so when working in a narrow space, the housing is There is a problem that it gets in the way and makes it difficult to use, and there is also a problem that the housing becomes bulky and makes it difficult to store.

The invention was made in view of the above points, and the main purpose is to provide an electric tool that is easy to use and has excellent storage properties.

The present invention will be described in detail below based on embodiments shown in the figures. The electric w) tool according to the present invention basically consists of an elongated housing Il+ in which a chuck t1 (chuck driven by a chuck 1) protrudes toward the tip m, and a front end connected to the rear end of this housing 131. are elongated bodies whose 0 axes are respectively connected to the housing (3).

The housing +B+ and the zinc screw 14 are formed into elongated bodies of approximately the same shape, and the housing 5 ring (3) has a temperature of ℃-

) forms a circular joint (!α) protruding from the rear end surface.Both halves +71 +81 pass through the through holes old IQi!l formed at the front and rear ends, and are thus connected, 7- T)11) is a bearing an in which the lip Q51 K @ formed at the front end part in the housing (3) is abutted and housed, and its output shaft t181 is housed in the cylindrical shaft (9).
The housing (31) is made to protrude through the front end of the housing (31), and the chuck (21 is attached to the tip of this output shaft (1).

A joint receiver 1241 is formed in which the is housed. Both halves '2[] lat + above housing l) + 31 are connected at both front and rear ends by screws 141 that connect the rear ends and screws 1261 that pass through the screw holes (c) formed in the rear ends of both halves 2011211. The battery (6) is housed between a pair of plates that protrude inside. battery(

In the books to be connected, fit each tongue piece (22 (231) into the through hole in the center of the joint IU with the boss □3o protruding from the inner surface,
As shown in Fig. 5, one tongue piece □□□ is screwed into the boss of the other tongue piece. ) is connected to Guri Sozu 141, and each boss example □□
□ is a fitting (1α through hole (121) that is rotatably fitted into the housing 1 relative to the zinc fitting (41).
3) is rotatable around the bosses t341 and 16t. In addition, on the inner surface of each tongue piece (22G), as shown in FIG. The second stopper protrusion protrudes, and when the grip 14) is rotated in one direction with respect to the housing 141, the first stopper protrusion □□□
is in contact with the first stopper surface (3'AK), and the housing 131 and the zinc 141 are aligned in a straight line, that is,
When the 0 axes of both are aligned and held in the first position and rotated in the opposite direction, as shown in Fig. 1 and Fig. 1g3,
The second stopper protrusion is brought into contact with the @2 stopper surface to make the housing 131 and the zinc 14) substantially perpendicular, that is, to make the 0 axis of both substantially perpendicular. be.

In addition, as shown in FIG. 4, an opening window (41) is formed on the same surface of the above-mentioned joint +101, and as shown in FIG. 3, FIG. 5, and FIG. A lead wire 42 connecting Tanabata (1) and the power switch (-) is connected to the housing (3) from the zinc fitting 141 through the opening window I4α.
) to be guided within.

Since the present invention has the following configuration, the first position where the zinc and the housing are in a straight line and the second position where both are bent can be selected and handled in accordance with the working conditions. It has the advantage of being easy to use, and it also has the advantage of being easy to store, as it can be folded or unfolded depending on the storage location and can be stored in a low-volume form. Furthermore, since it is freely connected to the housing, it has the advantage of being able to quickly convert between the two positions and easily switching between the two positions. 1-ta is housing
Since the battery is placed in the zinc case and the battery is placed in the zinc case, the weight balance between the two is good and it is easy to use.
