[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] Example:

[0025] See also Figure 1-Figure 2 The utility model provides a PCB circuit board with a protective structure, including a PCB circuit board body 1, and protective devices are installed above and below the sides of the PCB circuit board body 1. The protective device includes a bottom frame plate 2, a telescopic edge guard 3 and a hand-pull frame 4. The bottom frame plate 2 is in close contact with the side of the PCB circuit board body 1, and the telescopic edge guard 3 is fixedly installed on the inner edge of the bottom frame plate 2. The top of the telescopic edge guard 3 is provided with a hand-pull frame 4. The bottom frame plate 2 partially extends out of the side of the PCB circuit board body 1, and the parts of the bottom frame plate 2 extending out at the upper and lower positions are fixed by buckles.
