Detailed Description

The utility model will be further described with reference to the drawings and embodiments.

Please refer to fig. 1, 2 and 3 in combination, wherein,

fig. 1 is a front view of the present embodiment;

FIG. 2 is a schematic diagram of the structure at A in FIG. 1;

The gear with the directional rotating structure comprises a gear body 1, wherein the front side and the rear side of the gear body 1 are respectively provided with an outer ring 5, after the outer rings 5 are mutually attached to the front side and the rear side of the gear body 1 during installation, bolts are inserted into the inner cavities of adjacent first threaded holes and second threaded holes for installation, after the two outer rings 5 are mutually installed with the gear body 1, the two outer rings 5 can play a better positioning role, so that the inner cavity of the gear body 1 can not deviate when the inner ring 2 rotates, a plurality of second threaded holes are formed in the front side of the outer ring 5 near the edge, the positions between the plurality of second threaded holes and the first threaded holes are mutually matched, the plurality of first threaded holes and the plurality of second threaded holes are all arranged in an annular array shape by taking the center of the gear body 1 as a central shaft, the outer side edge of the gear body 1 is fixedly connected with a plurality of tooth blocks 3, the front side and the rear side of the gear body 1 are respectively provided with a plurality of first threaded holes, the inner cavity edge of the gear body 1 is respectively provided with a plurality of tooth grooves, the inner cavities of the plurality of tooth grooves are respectively movably inserted with a telescopic latch 6, one end of each adjacent telescopic latch 6 close to the center of the gear body 1 is respectively fixedly connected with two telescopic rods 7, the inner cavity of the gear body 1 is movably connected with an inner wheel 2, the center of the inner wheel 2 is respectively provided with an inserting hole 4, the outer side edge of the inner wheel 2 is respectively provided with a plurality of grooves, one side of the inner cavity of each groove close to the center of the inner wheel 2 is respectively provided with two positioning holes, the inner cavities of each adjacent positioning hole are respectively inserted with a telescopic rod 7, one ends of the two telescopic rods 7 far from the inner wheel 2 are respectively fixedly connected with one side of each adjacent telescopic latch 6 close to the inner wheel 2, the adjacent telescopic rods 7 are fixedly connected with positioning blocks 8 at one ends close to the center of the inner wheel 2, and springs 9 are fixedly connected between the adjacent positioning blocks 8 and the inner cavities of the adjacent positioning holes.
