When the lifting rod moves upwards, the pawl is upwards taken up by the rack, the pawl cannot limit the rack, and after the lifting rod rises in place and stops moving, the lower end of the pawl under the action of the return spring is clamped in a tooth groove on the rack, so that the limitation on the rack is realized, and the lifting rod is prevented from automatically sliding downwards. When the lifting rod needs to move downwards, the push-pull stud is rotated to pull the sliding seat towards the direction far away from the rack, and the pawl is separated from the rack, so that the lifting rod can move downwards conveniently.

Preferably, a T-shaped mounting groove is formed in the end, far away from the rack, of the sliding seat, a T-shaped mounting head is arranged at the end of the push-pull stud, and the mounting head is movably mounted in the mounting groove. The structure is convenient for the sliding base to slide in the sliding groove after the push-pull stud rotates.

Preferably, the position of the positioning pipe close to the lower end is connected with two cables, the cables are connected with cable columns on the ship body, and the two cables are symmetrically arranged on the left side and the right side of the positioning pipe. The two cables are connected with the positioning pipe, so that the positioning pipe is more stable and reliable to install.

Preferably, the support is connected with a bracket, and the driving gear is rotatably arranged on the bracket. The driving gear is arranged on the bracket, and the bracket facilitates the installation of the driving gear.

Preferably, the upper end of the lifting rod is connected with a protective end cover. The protection end cover plays a good protection role and prevents the lifting rod from sliding away from the positioning pipe.

Compared with the prior art, the beneficial effects of the utility model are that: the fixing device of the marine survey instrument capable of being lifted is used for installing the marine survey instrument, the reliability is good after installation, the risk of looseness does not exist, the accuracy of measurement is guaranteed, and the risk that the instrument slides to the seabed is avoided.
