Although this method can meet the versatility of electric tapping machine tapping applications, the operator directly manually positions the drill hole, which requires repeated corrections, resulting in time-consuming and labor-intensive work and low tapping efficiency.

A light beam emitted by the laser pointer is emitted through the laser irradiation port and projected onto a workpiece to form light spots, the plurality of light spots being arranged around the axis of the tapping machine head. When the head corresponds to a machining hole in the workpiece, the distance between the light spot and the edge of the machining hole can form a positioning reference, allowing an operator to intuitively and conveniently locate the position of the tapping machine, thereby quickly and effectively adjusting the position of the tapping machine, thereby reducing positioning time and improving tapping efficiency.

[0015] The body includes a mounting base, the mounting base is provided with a first mounting hole, an adjustment column is threaded into the first mounting hole, a first through hole is located on the adjustment shaft, the first mounting hole and the first through hole are coaxially arranged, a plurality of ports for the laser pointer light beam to pass through are provided on the hole wall of the first mounting hole, the ports are arranged circumferentially around the first through hole, and a first reflector is mounted on the adjustment column for guiding the light beam passing through the ports into the laser irradiation port.

After being split by the second beam splitter, part of the light beam enters the second opening, and the remaining light beam passes through the third reflector and impinges on the third beam splitter. After being split by the third beam splitter, part of the light beam enters the third opening, and the remaining light beam passes through the fourth reflector and impinges on the fifth reflector. After being reflected by the fifth reflector, the light beam emitted by the laser pointer is split into four ports, effectively reducing the manufacturing cost.
