Summary:A plug (0) is arranged on the lower portion of a gauge body (1), the upper portion of the gauge body (1) is connected with a middle connector (2) through threads, the middle connector (2) is connected with a rotary connecting terminal (3) through a shaft (13), a hanging ring I (4) is arranged at the upper end of the rotary connecting terminal (3), and a safety rope I (5), a connecting ring I (6) and a buckle I (7) are sequentially connected to the hanging ring I (4). The rotary connecting terminal (3) is in threaded connection with the left end of a connecting rod (8) through a threaded hole II (3-1), and the outer end of the connecting rod (8) is sequentially connected with a safety rope II (10), a connecting ring II (11) and a buckle II (12) through a hanging ring II (9). The gauge body is connected with gauge bodies of different sizes through the external thread connecting terminal, the gauge body is used for drilling rod water hole drift diameter, operation is safe, through double insurance of the safety
