The invention discloses an adapter which at least comprises two side walls A and a top wall B. The adapter is embedded in a driving arm connecting part, the side walls A and the top wall B serve as bearing supporting faces of the driving arm connecting part, and a first limiting part for limiting the driving arm connecting part to move forwards relative to the adapter is arranged at the front end of the adapter. The front ends of the two side walls A are provided with second limiting parts for limiting the upward displacement of the limiting clamping grooves of the connecting parts of the driving arms relative to the adapter; a protruding block without elastic deformation is arranged on the top wall B of the adapter, the protruding block is arranged in a limiting through hole of the connecting portion of the driving arm in a sleeved mode, the length X1 of the protruding block is smaller than the length X2 of the limiting through hole, and a limiting groove is formed in the side wall A of the adapter at least at the position corresponding to a positioning protruding point of the connecting portion of the driving arm and a moving track position corresponding to the positioning protruding point. The limiting groove is provided with a receding part allowing the positioning protruding point of the driving arm connecting part to move downwards and a locking part used for locking the positioning protruding point in the vertical direction, and the locking part is located at the rear end of the receding part.
本发明揭示了一种适配器,其至少包括两个侧壁A和一个顶壁B,适配器内嵌于驱动臂连接部,其侧壁A和顶壁B作为驱动臂连接部的承载支撑面,在适配器的前端设有限制驱动臂连接部相对于适配器向前位移第一限位部;在两侧壁A的前端设有限制驱动臂连接部的限位卡槽相对于适配器向上位移第二限位部;在适配器顶壁B上设有一不具弹性形变的凸块,凸块套置于驱动臂连接部的限位通孔内,且凸块的长度X1<限位通孔长度X2,适配器的侧壁A至少在相对于驱动臂连接部的定位凸点与之对应的移动轨迹位置形成限位沟槽,该限位沟槽具有供驱动臂连接部的定位凸点向下位移的让位部和用于在竖直方向锁止定位凸点的锁止部,锁止部位于让位部的后端。
