AI Technical Summary
In existing construction measurement devices, the heavy hammer body and the falling line are placed separately. When used, the heavy hammer body must be removed and the falling line must be installed first. There is a lack of limiting devices, which leads to the inability to leave the measuring device for other work when the maximum length is not required, which affects the working efficiency.
A construction measurement device is designed to drive the line coil to rotate and retract and release the drop line through the shaft, and limit the shaft through the connection between the groove and the shaft when the maximum length is not required. At the same time, the engaging device is used to limit and fix the weight hammer body to ensure that the weight hammer body is stored in the shell when not in use and protect it from damage.
It is possible to perform other work without the measurement device when the maximum length is not required, improve working efficiency, and ensure the stability and safety of the heavy hammer body through the limiting device.
