Abstract

The utility model discloses a surveying instrument, which relates to the surveying instrument field, and comprises a support and a distance measuring head, the support is provided with a sleeve, a sliding rod is slidably connected in the sleeve, the sliding rod is slidably connected with a fine tuning member, the fine tuning member comprises a lantern ring and an abutting ring, the abutting ring is in threaded connection with the outer peripheral wall of the lantern ring, and the distance measuring head is arranged on the lantern ring. A plurality of positioning holes are formed in the sliding rod, and inserting rods used for being inserted into the positioning holes are connected to the lantern ring in a sliding mode. Through the arrangement of the fine tuning part, when the sliding rod slides to a position close to a correct position with a hand, people adopt the fine tuning part to perform fine tuning on the position of the sliding rod, so that the position of the sliding rod is closer to the correct position, and the measurement effect of the distance measuring head is ensured.
