2. Description of the Related Art A conventional storage battery for an electric power tool has generally a structure that can be attached to and detached from an electric power tool main body in order to make up for a dead battery during work. The storage battery used in the power tool with a large amount of work had a large capacity and was accordingly heavy. As a method of fixing these heavy storage batteries to the power tool main body, the storage battery is positioned between the power tool main body and a rotating plate provided for holding the storage battery, one end of the rotating plate is pivotally supported by the electric tool main body, and the other end. The part was fitted and fixed to a protrusion provided on the power tool body or the storage battery. Further, when removing the storage battery from the main body of the electric tool, the engagement with the projection is removed with a finger, and the rotating plate is moved to a position where it does not hit the storage battery, and the storage battery is taken out.

SUMMARY OF THE INVENTION It has been necessary to increase the voltage of a storage battery as a means for powering up a cordless power tool. If the voltage of the storage battery is increased and the storage battery is held between the power tool main body and the rotating plate pivotally supported by the power tool main body, the storage battery works because of the gap between the storage battery and the main body and between the storage battery and the rotating plate. There was a possibility that the contact between the electrodes provided to connect the wiring of the storage battery and the main body of the electric power tool would spark due to the vibration and the contact would be defective. Therefore, the above structure hinders the development. Further, in the above structure, when the rotating plate is opened and the battery is removed, the rotating plate is pushed and pulled up by the fingers in the opening direction. Therefore, both hands must be opened, and the storage battery cannot be easily replaced with one hand. Therefore, there was a problem that work efficiency was poor.

According to the present invention, an insertion portion for inserting a storage battery into a power tool body and connecting wiring is formed in the power tool body, and a wiring connection portion is formed, and the power tool body and a column provided as an extension of the power tool body are formed. The pivotally supported plate is arranged so as to hold the storage battery in between, and the free end of the pivotal plate is locked to the slide lever provided on the electric tool body, and the operation of the slide lever causes the pivotal plate to move. The free end has a structure that can be engaged and disengaged, and by providing an elastic body in the power tool body, it acts so as to always apply a pressing force to the storage battery between the power tool body and the rotating plate. This is achieved by providing a storage battery side surface guide portion that holds down the side surface portion.

To store the storage battery, the storage battery 2 is inserted with the storage battery head 2a facing the insertion portion 3 and the concave groove 2b is slid into the storage battery side surface guide portion 9 on the rear side surface of the storage battery 2, and the rotating plate 6 is inserted. When the free end portion 6a of the above is pushed toward the slide lever 7, the rotating plate 6 also pushes in the storage battery 2 which is slightly pushed out by the elastic body 8. At this time, the hook portion 7a of the slide lever 7 is pushed backward by the free end portion 6a, and is pushed back by the spring 15 into the locking portion 6b provided at the free end portion 6a to be locked. At this time, the storage battery 2 is pushed by the elastic body 8 at the position of the center of gravity in the front direction.
It is pressed against the rotating portion 6 to eliminate a minute gap formed between the electric tool main body 1 and the rotating plate 6, and is stably fixed. The storage battery side surface guide portion 9 is provided with the recessed groove 2b so that the storage battery 2
Not only the rearward force but also the leftward and rightward force is supported, the rotating plate 6 and the slide lever 7 support the downward force and the load of the storage battery 2, and the insertion portion 3 and the elastic body 8 support the upper left and right sides and the front side. Supports directional force and stabilizes the whole.

According to the present invention, the storage battery is constantly pressed by the elastic body provided between the power tool body and the storage battery against the storage battery side surface guide portion for pressing the side surface of the storage battery of the power tool body and the rotating plate. Therefore, the storage battery vibrates at the same cycle as the power tool main body during the operation of the power tool, so that the contact failure can be reliably prevented. Further, when the storage battery is removed, the elastic body pushes the storage battery to open the rotating plate, so that it is not necessary to open the rotating plate with a finger, and work efficiency can be improved.
