Description

Technical Field

[0002] At present, the cooperation of a rotating motor and a rotating rod is often used to realize the reciprocating linear motion of a moving part. The rotating rod has a cross-arranged positive-spinning thread groove and a reverse-spinning thread groove. When in use, the moving part is used to be inserted and matched with the positive-spinning thread groove and the reverse-spinning thread groove. Then the rotating motor drives the rotating rod to rotate. The positive-spinning thread prompts the moving part to move in a first direction, and the reverse-spinning thread groove prompts the moving part to move in a direction opposite to the first direction, thereby realizing reciprocating linear motion of the moving part under the cooperation of the positive-spinning thread groove and the reverse-spinning thread groove.

However, the centering degree of clearance fit is not high and frequent adjustment is required. However, the adjustment method is relatively cumbersome and accessories need to be replaced according to the size, which is inconvenient to operate. Utility Model Content
