The circuit assembly also includes a first connector and a second connector disposed on both sides of the mounting housing. The first connector is connected to a power supply, and the second connector serves as a power output terminal connected to other chargers or loads.

2. A charger for a multi-unit power tool as claimed in claim 1, wherein: The front end of the charging card holder is a support platform extending horizontally forward, and the bottom of the rear end is provided with a boss for installing the charging connector; the upper part of the side walls on both sides of the boss is provided with limiting blocks that fit into the electrical equipment; the top of the limiting block is chamfered inward to form a guide position, and the bottom protrudes backward to form a locking position; the limiting blocks are respectively located on both sides of the boss, pointing towards the electrical equipment in the middle and limiting and fixing it.

3. A charger for a multi-unit power tool as defined in claim 2, wherein: The circuit assembly also includes an overload switch, a PCB main board, and at least one set of indicator light assemblies. The PCB main board is electrically connected to the charging connector, the overload switch, and the indicator light assemblies. The charging connectors are connected in parallel between each other. Each charging connector corresponds to one of the indicator light assemblies.

4. A charger for a multi-unit power tool as claimed in claim 3, wherein: The indicator light assembly includes an LED light and a light guide column; the LED light is electrically connected to the PCB motherboard, and its light-emitting surface is tightly connected to the bottom of the light guide column, while the top of the light guide column passes through the front end of the support platform to indicate charging.

5. A charger for a multi-unit power tool as defined in claim 3, wherein: The mounting housing includes a base, a front shell, a rear shell, a left protective frame, and a right protective frame. The base, front shell, and rear shell are assembled to form a charging body. The left and right protective frames cover both sides of the charging body and are fixedly assembled with screws to fix the base, front shell, and rear shell. The front end of the front shell is recessed inward to form at least one charging card holder.

6. A charger for a multi-unit power tool as defined in claim 5, wherein: The lower front end of the left protective frame bends to the right to form a first fixing position, and the upper rear end bends to the right to form a second fixing position; the first fixing position covers the front end of the charging body and restricts the front shell from aligning with the base, and the second fixing position covers the top of the charging body and restricts the front shell from aligning with the rear shell. The left protective frame and the right protective frame are symmetrically designed.

7. A charger for a multiple unit power tool as defined in claim 5, wherein: The mounting housing also includes a left decorative piece and a right decorative piece, which are respectively fixedly installed on both sides of the front housing; the upper part of the left protective frame is provided with a forward arch to form a handhold, and the lower part is provided with a horizontal through hole to form a mounting hole for installing the left decorative piece; the upper part of the right protective frame is provided with a forward arch to form a handle, and the lower part is provided with a horizontal through hole to form a mounting hole for installing the right decorative piece; The first connector and the overload switch are installed on one side of the left decorative piece, and a heat dissipation hole is provided on the other side; the second connector is installed on one side of the right decorative piece, and a heat dissipation hole is provided on the other side.

8. A charger for a multi-unit power tool as defined in claim 5, wherein: The rear shell has a charging heat dissipation hole that penetrates the plate surface in the middle and a fan air outlet that penetrates the plate surface at the bottom. The base has two upward protrusions on both sides of the front end to form a first positioning block and two upward protrusions on both sides of the front end to form a second positioning block. The inner side of the first positioning block is in contact with the front end face of the front shell. Both the first positioning block and the second positioning block have horizontal through holes, and are assembled and fixed to the front shell and the rear shell respectively by the cooperation of the through holes and screws.

9. A charger for a multi-unit power tool as claimed in claim 8, wherein: It also includes a heat dissipation component, which includes at least one heat dissipation fan electrically connected to the PCB motherboard; the air inlet of the heat dissipation fan and the rear shell points to the inner cavity of the mounting housing, and its air outlet points to the fan outlet of the rear shell.
