  • the connecting portion 523 of the hand-operated connecting rod 52 is moved into the limiting slot 403 in the rotation-limiting portion 40 of the first handle 41 via the first notch 401.
  • the retaining hooks 525 of the hand-operated connecting rod 52 are moved respectively into the hook-engaging slots 515 in the rotary knob 51.
  • the connecting portion 523 is movable between the first end 405 and second end 406 of the limiting slot 403 so that the maximum rotational angle of the hand-operated connecting rod 52 relative to the first handle 41 is 90°.
  • a C-shaped retaining ring 58 is received within the ring-engaging groove unit 404 in the first handle 41 to prevent removal of the first handle 41 from the first lock housing 31.

  • the rotary knob unit 50 is one piece configured as a rotary knob, and includes an upright wall 511, an actuation block 512, and a rotating shaft portion having an end surface 514' formed with a cross-shaped slot 516.
  • the cross-shaped slot 516 has two straight slot portions intersecting each other.
  • the lock-connecting rod 56 has an end engaging fittingly one of the straight slot portions of the cross-shaped slot 516 to allow for co-rotation of the lock-connecting rod 56 and the rotary knob unit 50.
  • Two first attracting members 54 are disposed fixedly on the rotating shaft portion of the rotary knob unit 50, and are spaced apart from each other by an angle of 180°.
  • the clutch gear 64 is sleeved rotatably around the rotating shaft portion of the rotary knob unit 50.
  • the second and third attracting members 65, 65' are disposed fixedly in the clutch gear 64.
