after positioning is completed, a user starts the fixed motor (112) through an external control mechanism, at the moment, the fixed motor (112) can drive the two groups of connecting worms (114) to rotate through the gear belt (111) and the connecting gear (113), at the moment, the two groups of connecting worms (114) rotate in the same direction in the positioning seat (104), and can be meshed with the connecting worm wheel (302) when the connecting worm (114) rotates, so that the connecting worm (114) can rotate on the upper part of the connecting worm wheel (302), and further the positioning seat (104) is driven to rotate on the limiting disc (308) until the angle pointer (105) designates the angle position reserved on the scale groove (305), and further the angle of the reference surface when a workpiece is machined is accurately adjusted;
when adding man-hour to the work piece, if need fix a position the outer reference surface in plane, when adjusting, user's accessible control mechanism starts outside motor, and outside motor can drive supporting mechanism through the connecting plate and overturn in two sets of spacing cassette insides this moment, appoint on the corresponding scale of calibrated scale until the inside location pointer of supporting mechanism, has improved the accurate nature of location, can adapt to the processing reference surface of each angle simultaneously.
