  • the mounting recess 66b of the cover plate 16b, 18b is disposed in a mounted state of the cover plate 16b, 18b on the housing unit 10b of the oscillating hand tool 68b in the main extension direction 26b of the oscillating hand tool 68b, viewed from the power cable 32b toward the tool holder 30b, respectively, after the groove 22b.
  • the first and second housing shells 12b, 14b are assembled perpendicular to the main extension direction 26b of the oscillating hand tool machine 68b.
  • the spring elements 46b of the spring element halves 42b of the first housing shell 12b engage in the grooves 48b of the spring element halves 44b of the second housing shell 14b.
  • the spring element 20b is respectively inserted into the groove 22b of the cover plate 16b, 18b.
  • the guide surface 60b of the groove 22b slides past the guide surface 50b of the spring element 20b.
  • the retaining surfaces 62b of the groove 22b and the retaining surfaces 52b of the spring element 20b which are each arranged at an acute angle, abut each other and form a positive connection between the first housing shell 12b, the second housing shell 14b and the cover plate 16b, 18b.
  • the detent element 64b of the cover plate 16b, 18b engages in the detent recess 54b of the first housing shell 12b. This prevents slippage of the cover plate 16b, 18b relative to the housing shells 12b, 14b.
  • the mounting recess 66b of the cover plate 16b, 18b covers the mounting recess 56b of the housing unit 10b. Through the mounting recess 56b, 66b of the cover plate 16b, 18b and the housing unit 10b engages a mounting screw 36b. As a result, the cover plate 16b, 18b is secured captively and releasably to the housing unit 10b of the oscillating handheld power tool 68b.
