Terminal wire hanging device with sag adjusting function

The invention discloses a terminal wire hanging device with a sag adjusting function. The terminal wire hanging device comprises a device body and a wire hanging assembly. The wire hanging assembly comprises a ratchet wheel frame, a ratchet wheel, a transmission shaft and a pawl limiter; the ratchet wheel frame is arranged on the device main body; the ratchet wheel is arranged in the ratchet wheel frame; the pawl limiter is arranged in the ratchet wheel frame and is used for limiting the rotating direction of the ratchet wheel; the transmission shaft and the ratchet wheel are coaxially and rotatably arranged on the ratchet wheel frame and used for installing an insulator. The ratchet wheel frame for hanging the insulators is arranged on the device main body, so that a single insulator can be mounted on the ratchet wheel frame, and the single insulator can be detached, replaced and maintained; meanwhile, the positive and negative rotation directions of the ratchet wheel can be controlled through the pawl limit
