Detailed Description

Referring to fig. 1 to 4, the utility model discloses a small-size two-way elasticity automatic brake spooler for flagpole that contains, including pivot 1, reel 8 and shell 6, down be one of them embodiment of this application:

be equipped with interior hexagonal through-hole in the pivot 1, through inserting the crank that has the hexagonal spanner or motor drive pivot 1 rotates, 1 one end outside of pivot is fixed to be equipped with dials ring 2, dials ring 2 and is the tourus that has fan-shaped opening 15 in the upper end.

A rotating shaft hole 11 is formed in the reel 8, the rotating shaft hole 11 is sleeved on the rotating shaft 1, and a limiting pile 5 is arranged at the position, corresponding to the fan-shaped opening of the shifting ring 2, of the reel 8; the limiting pile 5 is a cylinder or a cuboid.

Dial 2 outside rings of ring and be equipped with spacing spring 3, spacing spring 3 is the spring that the ring formed closely side by single steel wire, and spacing spring 3's both ends are kept off the card 14 towards the inboard bending spring that becomes, and the spring keeps off the card 14 and is located fan-shaped opening 15 inboard and lie in 5 both sides of spacing stake, and 3 outside hug closely and are equipped with solid fixed ring 4, and solid fixed ring 4 outside is fixed to be equipped with fixed plate 13, and fixed plate 13 links to each other with shell 6 is fixed.
