[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This type of fire-fighting facility reel maintenance placement rack is provided with a telescopic positioning mechanism. When the reel body needs to be extended, the extended reel is first pulled out from the inside of the reel body, and then the extended reel is rotated until the second arc groove is aligned with the first arc groove. At this time, the baffle originally stored is rotated out under the pulling force of the telescopic spring, and then when the reel body rotates clockwise, the baffle drives the extended reel to rotate in the same direction under the limitation of the baffle. Conversely, when the water pipe is released, in order to reduce the volume occupied by the reel body, it is only necessary to fix the reel body and rotate the extended reel clockwise at the same time. At this time, the baffle will be pressed by the inner wall of the first arc groove to be stored in the second arc groove. The operation is simple and will not fall off.

[0014] 2. This type of fire-fighting facility reel maintenance placement rack, when the reel body needs to be installed, first put the support rod between the convex plates on the left side of the lifting plate, and then start the second motor. At this time, the second motor will drive the driven wheel and the threaded rod to rotate, so that the lifting plate rises along the surface of the threaded rod. When it reaches the bottom surface of the vertical plate, align it with the left notch of the circular groove and continue to raise the lifting plate. When it reaches the upper wall of the circular groove, push the bottom plate toward the right. At this time, the slider will slide in the slide groove, and when the support rod is aligned with the right notch of the circular groove, lower the height of the lifting plate until the support rod is stably placed in the right notch of the circular groove, thereby avoiding the difficulty of artificially lifting and placing the heavier reel body, saving maintenance costs.
