The invention relates to a stop mechanism and torque adjustment mechanism for rotary tool, the stop mechanism can loosely keep the torque setting of dynamo-electric screwdriver (100), the stop mechanism includes a nose-shaped ring (103) which can be mounted on the casing (101) of the screwdriver (100) and has a series of torque setting positions which can be indicated as peak torque transferring from the gear case (104) to shaft of the screwdriver (100). The elastic stop part (108) joints the nose-shaped ring (103) with the gear case (104), so the nose-shaped ring (103) can be prevented away from movement of each torque setting position by means of elasticity of the stop part (108), and the nose-shaped ring (103) can be loosely kept on the proper position by means of elasticity of the stop part (108).

The invention discloses a method for controlling the labeling pressure of a servo labeling machine. The method comprises the following steps of: calculating the processing torque required by a servo motor to move a mounting head according to the labeling required pressure on the surface of a workpiece, and dividing the feeding stroke of the mounting head into S1 and S2; enabling the servo motor to drive the mounting head to move to a torque switching point according to the maximum torque at the stroke S1, and switching the torque of the servo motor into working torque at the torque switching point; and enabling the servo motor to drive the mounting head to move from the torque switching point to make contact with the surface of a workpiece according to the torque S2 to conduct labeling. The feeding efficiency of the mounting head is guaranteed, meanwhile, the labeling stability is effectively guaranteed, and workpiece damage caused by overshoot of the mounting head is avoided.
