The invention relates to the technical field of door opener components, in particular to a door opener quick clutch method, a spiral through groove is designed in a transmission shaft body, limiting through holes with the diameter larger than the width of the through groove are formed in the two ends of the through groove respectively, and structures of a positioning pin and a limiting piece are designed correspondingly; the limiting piece is connected to one side of the positioning pin, limiting is achieved through limiting cooperation of the limiting piece and the through groove, and the limiting stability and the smoothness of rotation adjustment can be both considered; compared with the prior art, the positioning pin has the advantages that the failure rate is greatly reduced, the abrasion resistance is high, the service life is long, if the limiting piece is excessively abraded, only the limiting piece needs to be replaced, the positioning pin does not need to be integrally replaced, the limiting piece is convenient to replace due to the structure of the through groove and the limiting through hole, the positioning pin does not need to be integrally separated from the inner hole, and the later maintenance cost is saved.
本发明涉及开门机部件技术领域，特别涉及一种开门机快速离合方法，通过在传动轴本体设计螺旋形的通槽，在通槽的两端分别设有直径大于通槽宽度的限位通孔，相应的设计了定位销和限位件的结构；限位件连接于定位销的一侧，利用限位件与所述通槽限位配合实现限位，可兼顾限位稳定性和转动调节的流畅性；大大降低了故障率，且具有很高的耐磨性，使用寿命长，若限位件过度磨损，只要更换限位件即可，不需要整体更换定位销，且通槽和限位通孔的结构也便于限位件的更换，不需要将定位销整体从内孔中脱出，节约了后期维修成本。
