Instrument height measuring device

The invention discloses an instrument height measuring device which comprises a telescopic measuring rod (1), a shell (2), a display screen (3) and a distance measuring system (4). The telescopic measuring rod (1) is installed in the middle of the top end of the shell (2). The display screen (3) is installed on the upper portion of the shell (2). The distance measuring system (4) is installed on the lower portion of the shell (2). The distance measuring system (4) comprises a microcontroller, a setting module, a display module, a power source and a laser distance measuring module. The setting module, the display module, the laser distance measuring module and the power source are connected with the microcontroller. According to the instrument height measuring device, the structure is simple, the production cost is low, the defect that a measuring device in the prior art is large in error and inconvenient to use is effectively overcome, and the instrument height can be conveniently and accurately measured through cooperation of the telescopic measuring rod and the laser distance measuring module.
