Splayed wine grape leaf curtain construction frame device

The invention discloses a splayed wine grape leaf curtain construction frame device which comprises a plurality of supports arranged in a linear row at intervals. A main vine traction wire which is arranged in the middle and located at the highest position and two sets of edge wires which are symmetrically distributed in the left-right direction with the main vine traction wire as the center are arranged between any two adjacent supports, and the main vine traction wire and the two sets of edge wires are distributed in a regular splayed shape to construct a splayed grape leaf curtain when observed from the lateral view angle. The edge wires extend horizontally, and the two ends of the edge wires are fixedly connected with the upper sides of any two adjacent supports respectively and used for supporting trunks of grape vines; the main vine traction wires extend horizontally, and the two ends of the main vine traction wires are fixedly connected with the upper sides of any two adjacent supports respectively and
