- the guide members are arranged approximately parallel to the surface normal of the base plate slidably on this.
- Displacement possibility of the two guide members perpendicular to the support surface of the base plate results in a corresponding vertical displacement of the second retaining bracket relative to the base plate.
- the second headband can be both parallel to the plane of the bearing surface of the base plate as well as moved perpendicular thereto and locked accordingly.
- the second leg facing away from the end portions of the guide members are coupled together via a carrier.
- the carrier causes in this respect a parallel or coupled displacement of the two legs. The raising or lowering of one of the two guide members thus leads directly to a corresponding lowering or raising of the other
- the carrier may in this case have an internal thread, which with a
- the carrier or the adjusting screw cooperate with a spring element, so that a
- Adjusting movement of the carrier against a spring tension can be done.
- the base plate in its support brackets facing the support surface at least one recess which is the inclusion of a head portion of the
- Rodents serves.
- the shape or the geometric configuration of the recess is adapted to the shape of the male head portion of the rodent.
- the depression serves in particular to receive a nose, eyes and / or forehead of the head of the rodent.
- the base plate is pivotally mounted via a hinge to a stand. In this way, the base plate can be pivoted largely freely in space to the intratracheal, pulmonary or dental
