Definitions

  • the object is achieved in that the coupling element is a ball which interacts with stop surfaces of the drive pinion and the spindle.
  • the design of the coupling element according to the invention enables economical production of the hand-held device since the ball is a commercially available item that can be bought in and the stop surfaces interacting with the ball can be attached directly to the spindle and the drive pinion. Another advantage is the small size of the coupling element and its low weight, which has a positive effect on the total weight of the hand-held device.
  • the stop surface of the spindle is preferably formed by a groove arranged on an outer circumferential surface of the spindle, at least the extent of the groove measured in the circumferential direction exceeding the corresponding extent of the coupling element designed as a ball. Stop surfaces in the form of a groove have the advantage that they can be produced economically and do not protrude beyond the outer contour of the spindle. Due to the special extent of the groove, the spindle can only be rotated to a limited extent in relation to the drive pinion in the engaged state.
  • the edge advantageously slopes toward the respective two circumferential ends of the groove counter to the setting direction.
  • the spring is expediently arranged between the coupling element designed as a ball and the drive pinion.
  • the spring is arranged between turned parts.
  • the spring will malfunction if the spring is located between a rotating part and a part arranged in a rotationally fixed manner relative to the housing. As soon as the rotating part rotates, there is friction between the spring and one of the parts. The frictional force creates torsional loads that act on the spring and have a negative effect on the function.
