[0002] At present, there are no safety measures to protect workers when they are carrying out photovoltaic construction on the roof, and when people are working on the edge of the roof, there is no safety protection, which can easily lead to the danger of construction workers falling. After searching, the patent with application number 202220895691.6 discloses a photovoltaic construction safety rope lock, including a connecting frame, whose two ends are respectively movably sleeved on one end of the first connecting rod and the second connecting rod; a connecting sleeve, which is rotatably arranged at the lower part of the mounting seat through a thread; an adjusting rod, which is threadedly connected to the mounting seat after passing through the connecting sleeve; a take-up device, which is movably arranged on the connecting frame; a winding reel, which is rotatably arranged on the rocker located inside the take-up device, for winding up the safety rope; a locking disc matching the toothed disc is arranged on the inner wall of the take-up device close to the toothed disc.

[0003] However, during actual use, the applicant found that the length of the device can be adjusted to adapt to roofs of different widths by sliding the first connecting rod and the second connecting rod out of the connecting frame. After use, although this structure can store the first connecting rod and the second connecting rod into the connecting frame, the structure of the connecting frame is still relatively long, which is not convenient for people to carry. In view of this, we propose a photovoltaic construction safety rope lock. Utility Model Content
