[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figure 1-4 The utility model embodiment is a power adapter with a wiring anti-loosening structure, which includes an adapter body 1 and an anti-loosening component 2. The upper surface of the adapter body 1 is fixedly connected with a boss 101, and the cross-section of the boss 101 gradually decreases from bottom to top. There are two bosses 101, which are axially symmetrically arranged. One end of the adapter body 1 is provided with a wiring head 102. The anti-loosening component 2 includes an adapter plate 201, and the adapter plate 201 cooperates with the adapter body 1. A handle 205 is fixedly connected to the middle of the adapter plate 201. An anti-loosening shell 203 is fixedly connected to one end of the adapter plate 201. The end surface of the anti-loosening shell 203 is provided with a receiving groove 204, and the receiving groove 204 cooperates with the wiring head 102. The other end of the adapter plate 201 is fixedly connected with a protective shell 206, and the protective shell 206 is positioned at the bottom of the adapter plate 201.
