[0036] The drill rod limiting steel plate 4 is a steel plate provided with a limiting circular hole 41 at the center, the diameter of the limiting circular hole 41 is greater than the diameter of the drill bit end drill rod 22, and the gap size between the limiting circular hole 41 and the drill bit end drill rod 22 is less than the maximum size of the allowed floating drill.
[0037] In order to facilitate installation, the drill rod limiting steel plate includes a lower steel plate and an upper steel plate which are fixed together by bolts, and the limiting circular hole is formed by splicing the lower steel plate and the upper steel plate.
