[0035] Please refer to Figures 1 to 7 As shown, it shows the specific structure of a preferred embodiment of the present utility model, which includes a power supply body 10 and an adapter 20.

[0036] The power supply body 10 is provided with a plurality of plug-in slots 101, and each plug-in slot 101 is provided with a first terminal 11 connected to the interior of the power supply body 10. In this embodiment, the power supply body 10 is provided with a mounting portion 12, and the mounting portion 12 has a mounting slot 102, and the plug-in slot 101 is located in the mounting slot 102; the left and right sides of the mounting portion 12 are symmetrically provided with sliding portions 13 facing outward. The power supply body 10 is provided with a pressing member 14 that moves in the up and down directions, and the upper end of the pressing member 14 extends upward from the upper end surface of the power supply body 10 to form a limiting portion 141; the pressing member 14 is exposed to the outside of the side wall of the power supply body 10 to form a pressing portion 142, and the outer surface of the pressing portion 142 is provided with an anti-slip surface 143. There are four plug-in slots 101 arranged in a horizontal arrangement; correspondingly, there are four first terminals 11.

[0037] The adapter 20 is detachably mounted on the power supply body 10. The adapter 20 is provided with a plurality of second terminals 21 connected to the interior of the adapter 20. Each second terminal 21 is inserted into a corresponding insertion slot 101 and contacts and conducts with the first terminal 11, thereby achieving a connection between the adapter 20 and the power supply body 10. The adapter 20 is provided with an interface 22 connected to the interior of the adapter 20. The interface 22 is used to communicate with an external data cable, so that when charging, the power supply body 10 can also be charged by plugging a conventional data cable into the interface 22 and switching through the adapter 20. In this embodiment, the adapter 20 is detachably mounted in the mounting slot 102. The lower end surface of the adapter 20 is provided with a slide groove 201 that cooperates with the sliding portion 13. The adapter 20 is slidably mounted on the power supply body 10 along the extension direction of the sliding portion 13 and the slide groove 201. The lower end surface of the adapter 20 is provided with a limiting groove 202 that cooperates with the limiting portion 141. The front end surface of the limiting portion 141 abuts against the rear side wall of the limiting groove 202 and limits the front and rear directions of the adapter 20. During installation, it is only necessary to drive the limiting portion 141 downward through the pressing member 14, and then slide the adapter 20 onto the power supply body 10 through the cooperation of the sliding groove 201 on the adapter 20 and the sliding portion 13 until the limiting portion 141 corresponds to the position of the limiting groove 202, and then release the pressing member 14 to allow the limiting portion 141 to extend upward into the limiting groove 202.

[0038] The number of second terminals 21 is also four. In other embodiments, the number of sockets 101, first terminals 11, and second terminals 21 can also be set to any number depending on the actual function of the power tool power supply, without limitation. The adapter 20 housing is formed by a base 23 and a cover 24. The interface 22 is sandwiched between the base 23 and the cover 24, and is exposed on the outer surface of the housing. This makes installation of the interface 22 more convenient. Simply install the interface 22 on the base 23 and then snap the cover 24 onto the base 23. There are three interfaces 22, two of which are located at one end of the adapter 20 and one at the other end. The multiple interfaces 22 facilitate the charging process and allow the power tool to charge electronic devices such as mobile phones through other interfaces while connected to an external charging power source, providing greater functionality. The interface 22 can be a Type-C interface, MicroUSB-A interface, or DC interface. USB-A and other interfaces can also be used depending on actual needs. This allows it to meet most data cable usage requirements. When charging, you can use a smartphone charger, a mobile phone data cable, a round hole DC cable, and connect the adapter 20 to the battery body 10, or connect the round hole DC cable to the power tool battery pack to charge the power tool battery pack. You can save the dedicated power tool battery pack charger and make good use of the user's mobile phone charger. When the adapter charges the power supply of the power tool, the charging voltage range is DC5V-72V. The specific voltage can be adjusted according to the power supply voltage of the power tool; the maximum power is 280W. This makes the charging process more convenient, saves users the cost of purchasing battery pack chargers, and provides a better user experience. The adapter 20 can intelligently identify the charger communication protocols of all mainstream mobile phones on the market, making it smoother to use.

[0039] At the same time, the adapter 20 is docked with the slot of the power tool battery pack, or the adapter is docked with the power tool battery pack through the round hole DC line, and the mobile phone data line is used to charge the mobile phone. When charging the mobile phone, it can intelligently match different models of mobile phones and output the corresponding voltage and power.

[0040] At the same time, through the power tool battery pack, combined with the USB-A port or TYPE-C port of the adapter, small electrical appliances such as LED lighting fixtures and small fans can be powered.

[0041] The adapter is equipped with an indicator light 25, which is internally connected to the adapter 20 and exposed on the outer surface of the adapter 20. The user can observe the operating status of the adapter 20 by observing the operating status of 25. The red light illuminates when the power tool battery pack is charging. When the power tool battery pack is fully charged, the red light turns off and the green light turns on. When the power tool battery pack is discharged through the Type-C port or MicroUSB-A port with the adapter, the red light illuminates.

[0042] The design focus of this utility model is that the adapter is detachably mounted on the power supply body, and is provided with multiple second terminals connected to the inside of the adapter. Each second terminal is inserted into a corresponding plug-in slot and contacts and conducts with the first terminal. Furthermore, the adapter is provided with an interface connected to the inside of the adapter, and the interface is used to communicate with an external data cable. With the adapter, when charging the power tool power supply, a common data cable can be connected to the interface, and then the adapter is used to complete the charging process. No special charging cable and plug connector are required, making the charging and use process more convenient and providing a better user experience.

[0043] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
