The axial fixing is via a detent means 54, 56. On the rotary head 40 the lower blade 50 is fixedly disposed and the upper blade 68 is pivotal on a bearing bush 58 of the rotary head. A pull rod 78 led through the bush 46 is anchored with a bent end to the movable upper blade laterally of the pivot axis thereof. The other end is anchored in an adjustment bush 82 which is adjustably fixed in an adjustment pin 84. The locking is by a plastic slide 24 which is disposed at the front end of the upper grip and can easily be displaced with the thumb to lock or unlock the lower grip or movable blade.
