p0065Fig. 33 shows a part of the charging stand 154, in particular the end wall 156 from the direction Y (Fig. 31), wherein the hair cutting apparatus 1 also chained lines and invisible parts of the charging stand 154 and the adapter are indicated 160 dashed.

p0066Referring to FIG. 31, the uncoupling of the adapter 160 will be described from the charging stand 154 with simultaneous coupling to the hair-cutting machine 1 in the following. For this, the hair clipper 1 is opposite to the direction of the arrow Y postponed until the hook to complete 157 approximately flush with the inner surface of the end wall 156th At the same time the pin is aligned 150 with the bore 164. The tabs penetrate 144 of the adapter into the recesses 153 of the clipper and the projection 151 of the hair clipper in paragraph 152 of the adapter so that the adapter 160 during the subsequent lifting against the direction of the arrow X the hair clipper 1 follows. The pin 159 is withdrawn from the bore 164 so that the pin 150 can enter 149 in the bore 164 due to the force of the spring. Thus, the adapter in the Y direction is locked to the hair clipper first This is shown again in FIG. 34.

p0067After completion of network operation (Fig. 34), the clipper be placed on the charging stand 154 such (slightly pressed down) that the position shown in FIG. 31 is taken again automatically, from a removal of the hair clipper for mains operation or for the accumulator operation, as already explained, is possible. The spherical formation and the displacement of the pin 159 does not occur terminals - even if the hair clipper should be 1 tipped during removal.

p0068Below is provided for the cable 12 recess in the end wall 156 of the charging stand 154 is provided with two further downwardly open recesses 165, 165 ', so that the cable 12 can be performed under the charging stand 154 for adapter 160th This laying of the cable looks attractive and can be carried out when a network operation can hardly be expected. The rearwardly extending cable also does not interfere.
