[0002] Electric drills typically rely on a rechargeable power source (such as lithium-ion or nickel-metal hydride batteries) for power, offering the advantage of high portability. When the drill is not in use, the power supply can be detached and used to charge other devices, such as lights and flashlights. However, the interface between the drill power supply and the drill is usually not a standard interface, requiring an additional adapter to be assembled before it can be used to power other products.

[0003] Chinese Patent CN202421205332.9 discloses an emergency power quick-connect socket, relating to the field of socket structure design technology. It includes a cabinet sleeve, an extension sleeve, and an adapter. One end of the extension sleeve is fitted onto the outside of the cabinet sleeve, and the other end is fitted onto the outside of the adapter. An axially oriented conductive post is provided inside the adapter, and a bolt is provided at the end of the cabinet sleeve. The conductive post has an axially penetrating cavity, and a threaded sleeve is installed within the conductive post, allowing it to rotate around its central axis. The bolt is screwed to the threaded sleeve, and a force-applying part is provided at the end of the threaded sleeve away from the cabinet sleeve, aligned with the cavity. This utility model's emergency power quick-connect socket has a reasonable structural design, and the adapter and cabinet sleeve are conveniently and quickly fixedly connected, reducing operational difficulty and improving production efficiency.

[0034] The adapter structure 1 includes a first housing 11, with a connecting part 12 on the lower side of the first housing 11. The connecting part 12 is used for installation and connection with the electric drill power supply 2, and the outer surface shape of the connecting part 12 matches the connection structure of the electric drill power supply 2. First sliding grooves 121 are provided on both sides of the connecting part 12 to connect to the electric drill power supply 2, and the adapter is achieved through the detachable connection of the first sliding grooves 121 to the electric drill power supply 2. A plug 122 is provided on the inner side of the connecting part 12, which is used for electrical connection with the electric drill power supply 2, enabling the adapter structure 1 to be powered. The first housing 11 has an output interface 111 for connecting external electrical devices. The output interface 111 is electrically connected to the plug 122, and outputs the converted electrical energy through the output interface 111. The output interface 111 can be a common interface such as USB. In this embodiment, two output interfaces 111 are used.

[0035] In one embodiment, the electric drill power supply 2 includes a second housing 21 and a battery 22, the battery 22 being located inside the second housing 21, specifically a rechargeable battery. The upper side of the second housing 21 has a mounting portion 23, which is matched and connected to the connecting portion 12. The mounting portion 23 has second sliding grooves 231 on both sides, which are matched and connected to first sliding grooves 121. The detachable connection between the adapter structure 1 and the electric drill power supply 2 is achieved through the matching sliding of the first sliding grooves 121 and the second sliding grooves 231.

[0036] The mounting section 23 has a slot 232 on its inner side, which matches the insert 122. The position of the slot 232 corresponds to the position of the insert 122. When the first slide groove 121 and the second slide groove 231 are installed and matched, the insert 122 is inserted into the slot 232. The slot 232 is electrically connected to the battery 22. The power of the battery 22 is output to the insert 122 through the slot 232, and then sent to the output interface 111. There are multiple inserts 122 and slots 232.

[0037] The second housing 21 has a power interface 24 on its side. The power interface 24 is electrically connected to the battery 22 and is used to connect an external circuit to charge the battery 22.

[0041] Furthermore, the surface of the connecting part 12 is provided with a limiting block 123, and the surface of the mounting part 23 is provided with a blocking block 234. When the starting point side of the first slide groove 121 abuts against the limiting protrusion 233, the limiting block 123 abuts against the blocking block 234. The limiting block 123 and the blocking block 234 further limit the relative sliding range of the first slide groove 121 and the second slide groove 231.

[0042] In one embodiment, a first circuit board 112 is installed inside the first housing 11, and the first circuit board 112 is electrically connected to the output interface 111 and the plug 122.
