Problems solved by technology
[0002] In the mine system of our country, a lot of work needs to be done underground, especially in the underground measurement operation. The wire ropes of some control points are very short, and the height of the staff alone cannot reach the line. The current common method is to step on the The commonly used working vehicle in the mine is used to tie the wire and rope, but the risk is high, the work efficiency is low, and the tie is inconvenient; another method is to use a ladder to tie the line, but it is very inconvenient to carry the ladder to the mine, so it is increased It reduces the difficulty of the underground bolting operation and reduces the work efficiency of the staff

Embodiment Construction
[0017] Embodiments of the present invention are further described below in conjunction with accompanying drawings:
[0018] like Figure 1-3 As shown, the mine portable tie line rod of the present invention is characterized in that: it comprises a first support rod 1, a second support rod 3, a third support rod 5 and a fourth support rod 7, and the first support rod 1 It is an inverted L shape. A plurality of threading holes 15 are arranged on the top of the first support rod 1. The diameters of the threading holes 15 increase successively from left to right. The first elastic locking card 2 of the head is matched with the first locking hole 13 on the top of the second support bar 3, and the second double-head elastic locking card 4 is arranged at the bottom of the second support bar 3, and the second double-head elastic locking card 4 is matched with the second double-head elastic locking card 4. The second locking hole 12 on the top of the third support rod 5 matches, and t...
