Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and by referring to preferred embodiments. It should be understood, however, that the numerous specific details set forth in the specification are merely set forth to provide a thorough understanding of one or more aspects of the present invention, which may be practiced without these specific details.

As shown in fig. 1-3, according to the utility model discloses a spirochaeta coupling shaft device, the device is including setting up coupling shaft 2 and spirochaeta 3 in the conveyer casing 1, the one end lateral wall of coupling shaft 2 is equipped with two semicircular grooves 4 relatively, and the straight line groove 5 has been seted up on the tip of coupling shaft 2 and be located between two semicircular grooves 4, be equipped with the woodchaeta 6 in two semicircular grooves 4, be equipped with a word key 7 in the straight line groove 7, the both ends of a word key 7 respectively with two 6 butts of semicircular key, the one end that the coupling shaft 2 is equipped with the semicircular key 6 is connected with spirochaeta 3, one of spirochaeta 3 is served and is equipped with the screens groove with the corresponding of semicircular key 6, the one end of semicircular key 6 is located semicircular groove 4, the other end is located the screens inslot. And a cutting sleeve 8 is arranged at the outer side of the sleeve. By arranging the I-shaped key 7 between the two semicircular keys 6, the force applied to the shaft head part of the connecting shaft 2 is dispersed by the I-shaped key 7, the connecting strength is increased, the shaft head crack of the connecting shaft 2 is reduced, and the service life of the connecting shaft 2 is prolonged.
