The multifunctional measuring ruler for construction measurement described in the present invention is provided with a retracting handle safety, a detachable conical head and a rotatable ruler hook, so that the tape can be fixed to prevent the conical head from hitting the person carrying it, making measurement more convenient and bringing better prospects for use.

[0004] However, during the use of the existing multifunctional measuring ruler for highway construction, due to the long highway construction distance, the length of the measuring ruler is relatively long. When it needs to be rolled up after the measurement, it can only be rolled up manually and cannot be rolled up automatically, resulting in a heavy workload for the staff. For this reason, we propose a multifunctional measuring ruler for highway construction. Utility Model Content
