Further, as shown in fig. 2, the modular power supply apparatus of the present invention further includes: and a slide cover plate 3.

Specifically, the structure of the skateboard deck 3 is shown in fig. 4.

Specifically, the socket 2 is provided with a first threaded hole 201, and the slide plate cover plate 3 is provided with a second threaded hole 302; mounting screws in the first screw hole 201 and the second screw hole 302; the slide cover plate 3 is mounted on the socket by screws.

The slide plate cover 3 restricts the slide plate 4 in the gap between the slide plate cover 3 and the socket 2 so that the slide plate 3 can only slide relative to the socket 2 without being displaced up and down.

Specifically, the structure of the socket 2 is shown in fig. 3.

Further, the socket 2 is provided with a slide guiding groove 202, and the slide 4 is provided with a protruding slide block 401; the slider 401 is slidably mounted in the slide guide groove 202. I.e., the slider 401 slides in the slider guide groove 202, the slider 4 slides with respect to the socket 2.

Further, the socket 2 is provided with a plug slot 204; the plug slot 204 is provided with a concave plug guide slot 206. When the plug 7 is plugged with the socket 2, the plug 7 is inserted into the plug slot 204, symmetrical plug guide grooves 206 are arranged on two sides of the plug slot 204, and symmetrical plug blocks are arranged on two sides of a plug-in part of the plug 7, as shown in fig. 2; when the plug 7 is plugged, the plug block of the plug 7 slides along the plug guide groove 206, and the plugging process of the plug 7 is completed.

Further, a dial 402 is provided above the slide plate 4.

Preferably, as shown in fig. 5, the dial 402 protrudes from the upper surface of the slide plate 4, so that the switching between the compressed state and the ejected state of the slide plate 4 is facilitated.

When the connection of the power supply module needs to be disconnected, the shifting block 402 is manually shifted backward, the sliding plate 4 moves the compression spring 5 backward, so that the plug 7 can slide relative to the socket 2, and the plug 7 is taken down.

Further, the slide cover plate 3 is provided with a groove 301, and the groove 301 is used for avoiding the shifting block 402 when the slide plate 4 slides. That is, the groove 301 is to pull the slide 4 without the slider cover 3 interfering with the slide 4.
