Can be fixed in close contact with the front direction of the housing 100.

The terminal groove 120 is formed toward the inside of the housing 100 on the rear upper side of the housing 100, and is formed to supply power to the power tool when the power tool is inserted and coupled to the tool insertion groove 110. The power supply pin may be inserted into the terminal groove 120.

The battery insertion groove 130 is formed to open the lower surface of the housing 100 in a "T" shape, and when viewed from the rear of the housing 100, one side of the lower part is "└" and the other side is "┘" It can be formed with a ruler.

Steps are generated on one side and the other side of the lower portion of the housing 100 by the battery insertion groove 130, and when the battery is inserted into the battery insertion groove 130, the battery is caught by the step formed in the lower portion of the housing 100. The power tool can be safely used because it is not detached even when it is lowered in the lower direction of the housing 100.

In addition, the battery insertion groove 130 is formed in the lower portion of the housing 100 from the rear to the front, so that the battery is coupled by sliding along the battery insertion groove 130 from the rear of the housing 100 toward the front.

In addition, a plurality of contact terminals 200 may be formed at positions respectively corresponding to the terminal grooves 120.

Since the coupling pin 300 is formed to protrude from the front end of the battery insertion groove 130 toward the rear, it may be inserted into and connected to the power terminal of the battery coupled to the lower portion of the housing 100.

Here, the coupling pin 300 is connected to the control board 400 provided in the housing 100 through a cable, and the power charged in the battery is transferred to the power supply pin of the power tool through the control circuit 410. It can be supplied to the combined contact terminal 200.
