包含化肥专用管壳体1防护带2和双扭簧3所述化肥专用管壳体1由通过螺钉连接的上化肥专用管壳体4与下化肥专用管壳体5组成;所述化肥专用管壳体1内设置有可转动棘轮转轴6所述棘轮转轴6两端设置有棘轮7且中间设置有矩形的固定槽8所述棘轮转轴6一端穿过上化肥专用管壳体4且穿出化肥专用管壳体1部分设置有驱动棘轮转轴6转动的盘簧9所述上化肥专用管壳体4外端面上设置有固定柱10且盘簧9另一端固定的设置在固定柱10上;所述上化肥专用管壳体4上设置有通过螺纹连接保护盘簧9盘簧盖11所述化肥专用管壳体1上相邻的设置有扁平出口12和钩体孔13且扁平出口12和钩体孔13相距5-20mm使扁平出口12处的防护带2和钩体孔13处的防护带2尾端近似重合,使防护带2适用于不同形状的电线杆;所述防护带2一端缠绕在固定槽8中,另一端穿出扁平出口12设置有弹簧钩14所述弹簧钩14包含钩体15和钩舌16所述钩体15设置在钩体孔13内,且通过钩舌16锁住钩体15防止钩体15滑出;所述防护带2与电线杆紧贴的一侧设置有增大摩擦力的防滑层(未标出)所述化肥专用管壳体1侧壁上穿设有通过双扭簧3阻止棘轮7转动的棘爪按钮17所述棘爪按钮17包含设置在化肥专用管壳体1内的棘爪18和设置在化肥专用管壳体1外连接棘爪18按钮19所述双扭簧3设置在化肥专用管壳体1内用于驱动棘爪18与棘轮7相贴合,使化肥专用管棘轮7单向转动;所述化肥专用管壳体1上与扁平出口12相对的方向设置有系于人身上的安全带的尾带20工作状态:1捆绑防护带时:工人将捆绑在身上的安全带系于尾带20上,爬到电线杆工作高度后,拉动弹簧钩14环绕电线杆一圈,并同时使棘轮7不断弹开棘爪18和盘簧9被压缩具有恢复弹力,此后将钩体15插入钩体孔13通过钩舌16锁住,
