[0022] The utility model provides a portable surveying instrument. When the surveying instrument is carried, a plurality of support legs are tied together using a binding rope, and then the binding rope is lifted to move the whole. However, this operation may cause the following problems: when the binding rope is used to bind the plurality of support legs, the binding rope has a small binding force, and the binding rope is easy to slide and deviate along the surface of the support leg, making it inconvenient to lift; the binding rope is difficult to loosen after being tightened, and the binding rope is easy to be lost during long-term use. By setting an adjustment structure, when the support leg needs to be rotated and opened and surveying operations need to be performed, the positioning rod is first rotated, and the positioning rod moves in a direction away from the positioning frame with the help of a thread, and the positioning rod drives the positioning plate to slide away from the binding strap along the positioning frame. At this time, the binding strap can slide along the inner wall of the positioning frame, and the binding strap is directly pulled to perform the line release operation. In this process, the binding strap causes the rotating shaft in the fixed frame to rotate, and then the support leg can be rotated to open. After the surveying operation is completed, the support leg is rotated to close, and then the rotating shaft is rotated in the opposite direction. The rotating shaft reels the binding strap into the fixed frame, and continues to rotate in the opposite direction. The user then moves the lever back and forth, and the lever is moved in a direction that is close to the positioning frame, and the lever drives the positioning plate to move in a direction that is close to the positioning frame, and the positioning plate drives the positioning plate to move in a direction that is close to the positioning frame, and the positioning plate is moved in a direction that is close to the positioning frame, and the positioning plate is fixed. The user slides his finger into the round hole and rotates the auxiliary disk, thereby rotating the lever back and forth, which is convenient for the user to rotate the lever back and forth, and the friction between the positioning plate and the strap is increased by the anti-slip protrusion, so that the limiting effect of the positioning plate is better, and the positioning plate is further limited by the sliding rod, so that the positioning plate is more stable when moving along the positioning frame. The entire device can be lifted by operating the handle, which is convenient for the user to move the device, and the position of the strap is further limited by the auxiliary frame. The strap slides and deviates along the two supporting feet, and the strap is used to bind and restrain several supporting feet, so as to prevent the supporting feet from rotating and opening during carrying, thereby improving portability. The strap has good binding effect, and the strap retraction and release operation is simple and convenient, and the strap is not easy to lose.

[0023] When surveying and mapping operations are carried out under sunlight, the sunlight shines on the display screen on the surveying and mapping instrument, making it difficult for the user to read the information. By setting up an auxiliary structure, the mounting plate is slid into the mounting frame from top to bottom, and then the baffle is rotated along the round rod to a suitable angle, and then the limit rod is rotated. The limit rod moves along the mounting plate toward the limit plate with the help of a thread until the limit rod is tightly against the limit plate, so that the rotation angle of the baffle is fixed. The friction between the limit plate and the limit rod is increased by an anti-slip groove, so that the limit rod has a better limiting effect on the limit plate. With the help of the mounting frame and the mounting plate, the baffle is conveniently installed on the surveying and mapping instrument body, and the baffle with an adjustable angle direction is used to block the top of the screen on the surveying and mapping instrument body, so that the user can read the information on the screen under sunlight.
