Matching hook of tunnel converge instrument for soft rock type wall rock

The utility model relates to a tunnel convergence indicator matching hooker that is applied to the soft-rock-type wall rock, which is characterized in that the matching hooker is provided with a straight rod with an overhead hook; one end of the straight rod is provided with an anchoring section (1) with notch (8), and the middle part of the straight rod is provided with a transitional section (2), and the other end is provided with a hooker (3); the hooker (3) is formed by an overhead-hook straight rod (7) and a transitional-section (2) with acute angle. With the matching hooker, the soft-rock engineering wall rock (class IV, class V and class VI) has the special equipped hooker, thereby overcoming the weakness that the connection position of the buckling rope and the hooker is easily changed and uncertain, and can specify a definite location precisely and can penetrate deeply in the soft wall rock, and can overcome the influence of the gap between the spraying layer and the wall rock, and can directly measu
