[0024] 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.

[0025] Reference Figure 1-5 The utility model embodiment is a self-locking open bellows, which includes: a lower half bellows 1, the outer surface of the lower half bellows 1 is fixedly connected to a connecting seat 2, the inner surface of the connecting seat 2 is rotatably connected to a rotating shaft 3, the outer surface of the rotating shaft 3 is fixedly connected to an upper half bellows 4, the outer surface of the upper half bellows 4 is fixedly connected to a snap box 5, the lower surface of the snap box 5 is provided with a snap groove 13, the upper surface of the lower half bellows 1 is in contact with the upper half bellows 4, the number of fixing devices 6 is two and distributed on the left and right, and the lower surface of the snap box 5 is in contact with the installation box 7.

[0026] The fixing device 6 comprises an installation box 7, a buckle 8, a connecting block 9, a fixing block 10, a connecting column 11 and a spring 12. The outer surface of the buckle 8 is slidably connected to the installation box 7. The end of the connecting block 9 away from the buckle 8 is fixedly connected to the fixing block 10. The outer surface of the connecting column 11 is slidably connected to the spring 12. The buckle groove 13 is adapted to the buckle 8. A limiting groove 14 is provided on the front surface of the installation box 7. The limiting groove 14 is adapted to the connecting block 9.
