In-hole geophysical prospecting test auxiliary device

The utility model relates to the field of geophysical prospecting devices, and discloses an in-hole geophysical prospecting test auxiliary device, which effectively solves the problem that the existing in-hole geophysical prospecting equipment is not easy to change the distance between probes so as to cause poor detection, and comprises a machine body, a drill bit is arranged at the bottom end of the machine body, and an adjusting assembly is arranged in the machine body. The adjusting assembly comprises installation blocks installed in the machine body at equal intervals, a connecting unit is installed between the two installation blocks, probes are installed on the outer sides of the installation blocks at equal angles, the top end of the machine body is in threaded connection with a screw rod, a rotating handle is installed at the top end of the screw rod, and a top block is installed at the bottom end of the screw rod. Due to the fact that the elasticity of each first spring is the same, the first springs
