The mounting base is provided with a measuring component; the measuring component includes a storage box, a winding drum, a connecting plate and a rotating handle. The storage box is provided at the top of the mounting base, and the winding drum is provided inside the storage box. The tape measure is wound on the groove of the winding drum. The connecting plate is provided on one side of the storage box, one end of the connecting plate is fixedly connected to the winding drum, and the other side of the storage box is fixedly connected to the rotating handle. A measuring component is added to this device, so that a single person can measure the land area and it is convenient to roll up the tape measure. At the same time, a fixing component is added to facilitate the fixing of the tape measure to prevent the measurement data from being affected by loose fixing, which is convenient for the staff to use.

[0004] Although the above device is convenient for fixing the tape measure, there are still some problems when using the device:

[0005] 1. The device does not have a horizontal adjustment mechanism, and it cannot adjust the end of the tape measure to be level with the outlet of the tape measure. Therefore, when measuring, a large measurement error will occur due to the tilt of the tape measure.

[0006] 2. The device does not have a night lighting mechanism. When it is dark at night, it is difficult to measure the land using the device.

[0007] In view of the above situation, technical innovation is carried out based on the existing land area measuring device. Utility Model Content
