Adjusting mechanism of clamping device for fire hose

The adjusting mechanism of the clamping device for the fire hose comprises a reel, a fixed plate is fixedly connected to the front side of the reel, a movable plate is movably connected to an inner cavity of the fixed plate, a connecting rod is fixedly connected to the top of the movable plate, and contracting mechanisms are movably connected to the two sides of the inner cavity of the connectingrod. According to the utility model, the reel, the fixed plate, the movable plate, the connecting rod, the contraction mechanism, the pulley, the clamping device body, the limiting mechanism, the limiting groove and the pull block are matched for use; the clamping device solves the problems that most of existing clamping devices for fire hoses are fixed; the fire hoses with different lengths havedifferent thicknesses after being wound; according to the adjusting mechanism of the clamping device for the fire hose, the problems that a fixed clamping device cannot clamp fire hoses with differentlengths, the practicabilit
