Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 2The utility model provides an embodiment: a joint protection device for a constant voltage power supply, comprising a protective shell 1 and a connecting block 2, wherein the protective shell 1 keeps the internal joint stable during use, an external end of the connecting block 2 is fixedly connected to a connecting shaft 3, which can transmit power to an external structure, and the other external end of the connecting block 2 is fixedly connected to a connecting shaft 4, which is a structure for transmitting power, and the external rotation of the connecting shaft 4 is connected to a connecting block 5, which can limit the internal protective shell 1, and the top of the connecting block 5 is rotatably connected to a rotating shaft 6, which is used to connect multiple structures to enable movement, and the external of the rotating shaft 6 The outer side of the sleeve 11 is fixedly connected to the outer side of the sleeve 11, and the outer side of the sleeve 11 is provided with a driving assembly to provide power for the fixation of the device. The driving assembly includes a pressing plate 12, and the outer side of the pressing plate 12 is fixedly connected to the outer side of the sleeve 11. The inner side of the sleeve 11 is rotatably connected to a rotating rod 13, and the outer side of the rotating rod 13 is fixedly connected to two connecting rods 14.

[0023] like Figure 1 and Figure 3 As shown: the adjacent sides of the two protective shells 1 are fixedly connected with a cylinder 15, so that the internal structure remains stable during the sliding process, the inside of the cylinder 15 is slidably connected with a slide rod 16, which can slide inside the cylinder 15, and a reset component is arranged on the outside of the slide rod 16, which can store elastic force through a spring 17 so that the structures at both ends have power to reset, and the reset component includes a spring 17, one end of the spring 17 is fixedly connected to the inner wall of the protective shell 1, and the other end of the spring 17 is fixedly connected to the outside of the splint 18, and the adjacent sides of the two slide rods 16 are fixedly connected with the splint 18.
