Claim:
1. A coupling mechanism for connecting a wiper to wiper arms with different width specifications, comprising: connector including a body having two outer side walls, a stopping portion formed on one end of the body, and an engaging member formed on a top surface of the body; and two width-adjusting spacer members respectively arranged on the two the outer side walls of the connector at an end of the connector opposite to the end formed with the stopping portion, wherein each of the width-adjusting spacer members is of a plate-type structure and is pivotally connected to the connector through a pivotal portion, each of the two width-adjusting spacer members is rotatable about the pivotal portion; wherein when connecting the coupling mechanism to a wiper arm with a width conforming to a first width specification, the two width-adjusting spacer members are rotated toward the two outer side walls of the connector, respectively, until the two width-adjusting spacer members are parallel to the two outer side walls of the connector, the two width-adjusting spacer members abut against an inner wall of the wiper arm, and a distance between outside surfaces, which are surfaces facing the inner wall of the wiper arm, of the two width-adjusting spacer members is equal to the width conforming to the first width specification, the outside surfaces of the two width-adjusting spacer members abut against the inner wall of the wiper arm; wherein when connecting the coupling mechanism to a wiper arm with a width conforming to a second width specification, the two width-adjusting spacer members are rotated away from the two outer side walls of the connector, respectively, until the two width-adjusting spacer members are parallel to each other and are respectively coplanar with the two outer side walls of the body, and both of the two width-adjusting spacer members and two outer side walls of the body abut against the inner wall of the wiper arm, and a distance between outside surfaces, which are surfaces facing the inner wall of the wiper arm, of the two width-adjusting spacer members is equal to a width between the two outer side walls of the connector, and is further equal to the width conforming to the second width specification; wherein the width conforming to the first width specification is greater than the width conforming to the second width specification.
