For transmission shaft cooperation installation transmission shaft matching hole, the fit key be side be C-shaped irony structure, the C of the fit key
The equal formed by integrally casting of upper and lower side of shape structure has threaded connection key, and the upper surface center that key is threadedly coupled described in two groups offers spiral shell
Pit.
Preferably, the link block offers the irony structure of first through hole for side, the axle center of the first through hole with
The axis parallel of transmission shaft matching hole that key center opens up is threadedly coupled, the center of the upper plane of the link block offers
Second through-hole.
Preferably, the symmetrical formed by integrally casting of the periphery of the transmission shaft has two groups of convex keys, and two groups of convex keys are square key,
Keyway is offered with the transmission shaft matching hole upper and lower ends of transmission shaft cooperation installation, keyway described in two groups and two groups of convex keys
Size it is identical and cooperation installation.
Preferably, the threaded hole opened up on key that is threadedly coupled is fastened by the cooperation of bolts and nuts, described
Pad is equipped with washer between screw bolt and nut.
The technique effect and advantage of the present invention：The use in sewing machine cloth feeding crank, link block, fit key and threaded connection key are
The irony structure of formed by integrally casting offers the transmission shaft matching hole for transmission shaft cooperation installation, and transmission shaft centered on fit key
The keyway cooperation that there are two groups of convex keys and transmission shaft matching hole upper and lower ends to open up of the symmetrical formed by integrally casting of periphery install so that peace
Assembly and disassembly are more convenient, and the cooperation installation of convex key and keyway is so that the connection between transmission shaft and fit key more steps up
Gu the use in sewing machine cloth feeding crank, rational in infrastructure, connection is easily installed and dismantles while fastening, has higher practical valency
Value.
