AI Technical Summary
Existing hollow drum equipment may bend or break due to excessive extension during tapping, affecting detection accuracy and equipment lifespan.
A hollow detector was designed. Through a combination structure of handle, fixing rod, docking rod and connecting rod, and with the cooperation of spring and fixing seat, the device can be telescopically fixed. It is equipped with a light to assist detection, prevent the device from bending due to excessive length, and provide light source for detecting fine details.
It improves the stability and detection accuracy of the equipment, reduces the maintenance cost, extends the service life of the equipment and the accuracy of detection, and facilitates relocation and prevents loss.
