Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The invention provides a mining universal anchor rod nut fastener which comprises an upper clamp body 1, a lower clamp body 2, a spring 4, a rod body 6 and a handle 7, as shown in figures 1 and 2.

The pliers head is provided with an upper pliers body 1 and a lower pliers body 2 hinged with the upper pliers body 1, and the upper pliers body 1 and the lower pliers body 2 are clamped to form a jaw for clamping a threaded fastener. The threaded fastener may be a bolt, a nut, or an anchor nut. The body of rod 6 is connected with the lower plier body 2 through connecting rod 8, and connecting rod 8 slope sets up, and the body of rod 6 is parallel to each other with the lower plier body 2, but both are not on same straight line. The handle 7 is vertical to the rod body 6 and is arranged at the tail end of the rod body 6.

Because the daily well descending goes to tunnel or maintains the working face, detects the engineering quality, when using electron anchor rod ergograph (EZ-300), because electron anchor rod ergograph spanner is whole for the straight line form, but some regional help drum is relatively serious, leads to the spanner head can't overlap on the anchor rod nut, even if the self-control "sleeve pipe" of district team also has such a problem, if can't detect regional support quality unqualified, then has certain potential safety hazard.
