The present invention discloses a crane wing spray structure comprising a column； a sliding link set is slidably disposed on the column； a first link assembly is coupled to a first extension bar by a first swing bar, the first One end of a swinging rod is pivotally disposed on the column, the first swinging rod is pivotally connected to the sliding link set； and a second connecting rod is connected to a second extending rod by a second swinging rod, the second swinging rod One end of the first swinging rod is pivotally connected to the sliding link set； one end of the first pulling rope is fixed to the sliding link set, and the other end is fixed to the first extending rod； a second pulling rope One end is fixed to the sliding link set, and the other end is fixed to the second extension rod； wherein the sliding link set moves up and down relative to the column, and the first link assembly and the second link assembly are folded and unfolded, The first pull cord and the second pull cord pull the first extension rod and the second extension rod in a state in which the first link assembly and the second link assembly are unfolded. This allows for a smaller height when folded.本創作揭示一種鶴翼式噴霧結構，係包含一立柱；一滑動連桿組可滑動地配置在該立柱上；一第一連桿組件由一第一擺動桿連接一第一延伸桿，該第一擺動桿的一端樞設於該立柱，該第一擺動桿樞接該滑動連桿組；一第二連桿組件，係由一第二擺動桿連接一第二延伸桿，該第二擺動桿的一端樞設於該立柱，該第二擺動桿樞接該滑動連桿組；一第一拉繩一端固定在該滑動連桿組，另一端固定在該第一延伸桿；一第二拉繩一端固定在該滑動連桿組，另一端固定在該第二延伸桿；其中該滑動連桿組相對該立柱升降移動，該第一連桿組件及該第二連桿組件產生收合及展開，在該第一連桿組件及該第二連桿組件展開的狀態下，該第一拉繩及該第二拉繩拉引該第一延伸桿及該第二延伸桿。藉此收合時可以具有較小的高度。
