Convenient-to-use mechanical tool measuring instrument for measuring tool holder and tool tip

The invention discloses a convenient-to-use mechanical tool measuring instrument for measuring a tool holder and a tool tip. The upper side of a base is connected with a rotating device, the upper side of the base is slidably connected with a horizontal adjusting device, and the upper side of the horizontal adjusting device is slidably connected with a vertical adjusting device. The upper end of the rotating device is detachably connected with the tool holder of a to-be-measured tool. A main shaft of the rotating device is arranged in the base, a tool holder connector is arranged at the upperend of the main shaft, the outer wall of the main shaft is connected with a driving part, and the lower end of the main shaft is connected to the bottom of the base in a supported mode through a supporting part, so that the main shaft rotates under driving of the driving part. The defects that in the prior art, the requirement for precision is low, and the requirement for low-cost, rapid and simple tool measurement cannot be met are overcome. According to the convenient-to-use mechanical tool measuring instrument for measuring the tool holder and the tool tip, the overall structure is simple,the requirement for measurement precision can be met, the measurement effect of multiple dimensions can be facilitated, and the requirement for rapid, low-cost and simple measurement is met.
