A deep hole wire pliers

Abstract

The invention relates to a deep hole wire cutter. The deep hole wire cutter comprises an outer cutter, an inner cutter and a pull rod, wherein the outer cutter comprises an outer shear opening, an outer pipe and a supporting plate, the outer shear opening is formed in the head end of the outer pipe, the supporting plate is arranged on the outer wall of the outer pipe, the inner cutter comprises aninner shear opening and an inner pipe, the inner shear opening is connected to the head end of the inner pipe, the inner pipe is inserted into the outer pipe, moreover, the inner shear opening and the outer shear opening are oppositely arranged, the pull rod comprises a first rod and a second rod, the tail end of the second rod is perpendicularly connected to the first rod, the connecting position between the first rod and the second rod is hinged to the supporting plate, the head end of the second rod is hinged to the inner pipe, and the head end of the first rod is connected to the outer pipe through a stretching spring. According to the disclosed deep hole wire cutter, the structure is simple, the length can meet the requirements of the width and the small aperture of a coal column, moreover, the lengthening function is achieved, up-down meshing of a front-end cutter opening is controlled through front-back pulling of a tail handle, a lower meshing opening is provided with barbs (namely, grooves) so that a diamond mesh wire can be accurately hooked, and a to-be-cut-off object can be accurately positioned in a blind area state.

Description

technical field [0001] The present invention relates to the technical field of wire cutters, and more particularly, relates to a deep hole wire cutter. Background technique [0002] At present, in the field of wire cutter technology, due to the limitations of the wire cutter itself, the space used is limited. For example, in Jining No. 3 Coal Mine, when a narrow coal pillar was left along the goaf roadway for reinforcement with expansion-locking anchor cables, it was discovered through drilling holes that there were abandoned anchor nets and shotcrete supports on the side of the goaf, and most diamond-shaped nets It has not yet been damaged. The two-way reinforced anchor cable needs to pass through the diamond-shaped net to better exert its locking force. The existence of the diamond-shaped net makes it difficult for the anchor cable to pass through the front pocket. above the borehole. [0003] Based on this, it is a technical problem to be solved urgently for those skill...
