The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and probe chamber is provided with the mounting groove I of installation shaft elastic spring I.

The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and transit joint is provided with the mounting groove II of installation shaft elastic spring II.

The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, overlaps on I outer wall be welded with tungsten carbide wear resistant layer I in torsion pass.

The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, overlaps on II outer wall be welded with tungsten carbide wear resistant layer II in torsion pass.

Compared with prior art, when the utility model is subject to shock loading and rotary torque vectorial force, torsion pass cover I, II not only can not come off, and prevents bit body, probe chamber, excessively joint that relative gyration occurs by the transmission of torsional forces, and making it remain is an entirety; Utilize the tungsten carbide wear resistant layer that torsion pass puts, enhance anti-wear, extend application life.The utility model is reasonable in design, novel structure, easily manufactured, stable and reliable for performance in construction operation, thoroughly solve the problem that no-dig technique starter comes off when construction operation, bore pilot hole once success, saved construction cost greatly, improve work efficiency, stop the accident potential of guiding pore-forming.
