第一卡环211能使传扭杆23更加稳定地传递扭矩，限制传扭杆23、悬挂筒31的轴向位移，避免传扭杆23、悬挂筒31的松脱。
The outer wall of the valve core 52 is provided with a valve core tapered surface 523 capable of matching with and hermetically abutting against the valve core hole tapered surface, and one end of the valve core 52 is provided inwardly with a first passage hole 521 capable of communicating with the valve core hole 511 and the valve body communication hole 512, and the other end of the valve core 52 is provided inwardly with a second passage hole 521 capable of communicating with the piston cavity 40 and the valve body communication hole 512.
进一步，如图1、图2、图3、图4示，连通阀结构5包括抵靠套设于芯轴1的外壁和连接盘体21的内壁之间的阀体51，阀体51的内壁与芯轴1的外壁之间设置有密封圈；芯轴1的外壁上设置第一台阶部12，连接盘体21的内壁上设置直径呈减小设置的第二台阶部212，阀体51的一端面顶抵于第一台阶部12上，在本实施方式中，第一台阶部12上设置有多个向下延伸设置的第一定位销121，阀体51的一端面上设置有能卡设第一定位销121的卡设孔，阀体51通过第一定位销121实现周向固定；阀体51的另一端面顶抵于第二台阶部212上，在本实施方式中，为了使阀体51的轴向定位更稳定，芯轴1位于阀体51下方的位置套设有阀体卡环14，阀体51的底面顶抵于阀体卡环14的顶面上；阀体51内设置上下贯通的阀芯孔511，阀芯孔511内滑动设置有阀芯52，阀芯52的一端设置直径呈减小设置的阀芯凸柱部，阀芯52位于阀芯凸柱部的底部位置处构成阀芯台阶部，阀芯凸柱部的外侧套设阀芯弹簧53，阀芯弹簧53的一端顶抵于第一台阶部12上，阀芯弹簧53的另一端顶抵于阀芯台阶部上，阀芯52穿出阀体51的另一端位于驱动筒的内腔中；芯轴1的侧壁上设置有第一连通透孔13，阀芯孔511的侧壁上设有与第一连通透孔13连通设置的阀体连通孔512，阀芯孔511内设置有直径自上而下渐缩的阀芯孔锥面，阀芯52的外壁上设置有能与阀芯孔锥面匹配密封抵靠卡止的阀芯锥面，阀芯52的一端向内设置有能连通阀芯孔511与阀体连通孔512的第一通道孔521，阀芯52的另一端向内设置有能连通活塞腔40与阀体连通孔512的第二通道孔522，第一通道孔521的底部开口位于阀芯锥面的上方，第二通道孔522的顶部开口位于阀芯锥面的下方。
The first passage hole 521 has a bottom open located above the valve core tapered surface, and the second passage hole 522 has a top open located below the valve core tapered surface.
阀芯52用于打开或关闭芯轴1的内腔中流体的流动通道，实现流体通道的切换，阀芯弹簧53推动阀芯锥面密封抵靠卡止于阀芯孔锥面上时，第一通道孔521通过阀体连通孔512、第一连通透孔13与芯轴1的内腔连通，阀芯锥面与阀芯孔锥面构成的锥面密封，有效阻隔活塞腔40和芯轴1的内腔。
When the valve core spring 53 pushes the valve core tapered surface to hermetically abut against and be locked to the valve core hole tapered surface, the first passage hole 521 communicates with the inner cavity of the spindle 1 through the valve body communication hole 512 and the first communication through-hole 13, and the valve core tapered surface and the valve core hole tapered surface form a tapered surface sealing, effectively blocking the piston cavity 40 from the inner cavity of the spindle 1.
