Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-3, a tool capable of rapidly measuring the depth of an internal thread of a hole comprises a support plate 1, pillars 2 are symmetrically welded on the lower surface of the support plate 1, vertical rods 3 are slidably connected to both sides of the lower surface of the support plate 1, a scale 4 is vertically arranged on the side wall of each vertical rod 3, a first through hole is formed in the support plate 1, a push rod 5 is movably arranged in each through hole, an insertion rod 6 is welded at the bottom end of each push rod 5, a groove 7 is vertically formed in each insertion rod 6, a second through hole is formed in each side wall of each groove 7, a movable rod 8 is movably arranged in each through hole, a stop block 9 is fixed at the end, close to each movable rod 8, a spring 10 is connected between the two stop blocks 9, a vertically arranged stop rod 11 is fixed at one end of the movable rod 8 positioned on the same side, a cross rod 12 is slidably connected to the side wall, far away from each stop rod 11, and a cushion block 13 is fixed at the bottom end of the cross rod 12, a mounting block 14 is fixed at one end of the cross bar 12, and a pointer 15 is fixed at the bottom of one side wall of the mounting block 14.
