Furthermore, the driving instruction controller comprises 3 function buttons for starting, gear selecting and zero setting and an engagement depth display screen, wherein the starting button is used for electrifying the control driving motor assembly, and the gear buttons are used for selecting the measurement precision and are respectively 1mm, 0.5mm and 0.2 mm; the zero button may enable initial zero.
Further, the driving instruction controller further comprises an emergency stop button for emergency stop when an abnormality occurs in the detection process.
Furthermore, the driving motor assembly is composed of a stepping motor and a speed reducer, and accurate axial movement can be achieved.
Has the advantages that: in the process of overhauling the elevator, the structure of the utility model can realize automatic detection, thereby avoiding artificial measurement errors; secondly the device simple operation, it is safe in utilization, detection lock depth of engagement that can convenient and fast can carry out the quick affirmation to the electric lock again.
