The existing anchor tension gauge is designed for general anchors, and the anchor can directly pass through the center hole of the anchor tension gauge. In recent years, my country has widely used pipe-seam anchors in the support of broken rock masses in mine tunnels. Due to the diameter and structure of the pipe-seam anchor, it cannot directly pass through the center hole of the anchor tension gauge, and when testing, there is a problem of connection with the anchor tension gauge. Therefore, a suitable tension gauge connector is needed.

[0003] In this regard, China's utility model patent application number is CN201220247872.4, which discloses a pipe seam anchor tension gauge connector, in which a connecting sleeve is provided on the pull rod, an inner sleeve is screwed on the outer side of the connecting sleeve, and a wedge-shaped clip that can fix the pipe seam anchor is designed inside the inner sleeve. The pull rod and the pipe seam anchor can be fixed by using the wedge-shaped clip and the above-mentioned structure, so as to facilitate the later detection of the anchoring force of the anchor.

[0004] However, according to the actual application, the specifications of the anchor tension gauges used are different, the apertures of the center holes of different anchor tension gauges will be different, and the sizes of the pull rods used and the connecting sleeves integrally formed therewith will also change. The above-mentioned inner sleeve is not suitable for fixing the connecting sleeve at the end of the pull rod, which makes the above-mentioned pipe seam type anchor tension gauge connector limited.

[0005] Therefore, the present application needs to apply for a more versatile pipe seam type anchor rod tension gauge connector to improve the above problems. Utility Model Content

[0008] The anchor tension gauge connection mechanism includes a pull rod that can pass through the center hole of the anchor puller and a pull block and a nut respectively arranged at both ends thereof. An adjustable connecting piece is also fixed between the separated sides of the pull block and the ring, and the connecting piece is suitable for limiting the pull blocks and the rings of various different diameters.

[0009] Preferably, the connecting piece includes a connecting sleeve with an internal thread on the inner side, and the connecting sleeve is provided with a plurality of external thread sleeves with successively smaller diameters on one side of the internal thread, wherein several or one of the external thread sleeves are movably fitted to a side of the pulling block close to the anchor puller, and the connecting sleeve is provided with a clamping portion in pairs on a side away from the internal thread for clamping the circular ring.
