Description

Technical Field

[0001] The utility model belongs to the technical field of total stations, and particularly relates to a portable total station. Background Art

[0002] In order to facilitate the use of total stations, people have designed portable total stations. Although existing portable total stations can meet the needs of measurement and portability, and during use, they will use a collection structure to support the support legs, but usually the collection structure is used to collect and fix the support legs in a clamping manner. During use, it is easy to cause the collection structure to shake and fall off relative to the support legs, and the support legs cannot be stably collected and fixed, which will make it difficult for users to move the device conveniently, thus causing great inconvenience to people's use.

[0003] For example, a utility model with a publication number of CN 216447780 U discloses a portable total station. In the technical solution of this patent, a collecting tray is fixedly connected to the lower end of the auxiliary rod, a docking groove is provided on the side of the collecting tray, a fixing groove connected to the docking groove is provided inside the collecting tray, and the surface of the supporting leg is arranged inside the fixing groove. Since the supporting leg is fixed to the collecting tray by snap-fitting, there is no fixing structure for fixing the connection between the supporting leg and the collecting tray. Therefore, it is easy for the supporting leg to loosen and fall off relative to the collecting tray, and the supporting leg cannot be stably limited and fixed, so it cannot fully meet people's usage needs.
