Adjustable anti-explosion wire spool

The utility model discloses an adjustable explosion-proof wire spool which comprises a rotating rod and two groups of wire spool assemblies, each wire spool assembly comprises a first semi-ring plate and a second semi-ring plate, one end of each first semi-ring plate is rotatably connected with one end of the corresponding second semi-ring plate through a connecting shaft, and the other end of each first semi-ring plate is rotatably connected with one end of the corresponding second semi-ring plate. By arranging the adjusting mechanism, the multiple connecting rods in the state of horizontally moving towards the outer side drive the multiple arc-shaped plates to synchronously conduct expansion movement towards the outer side, and therefore the multiple arc-shaped plates in the expansion movement state increase the inner diameter size of the anti-explosion wire spool, and the anti-explosion wire spool is convenient to use. The connecting rods horizontally moving towards the inner side drive the arc-shaped plat
