Tatooing pincers for marking ears of animals

Tatooing pincers for marking ears of animals by injection of a tatooing liquid, said pincers comprising:

• a portable support structure,
• a first jaw carried by said support structure,
• a second jaw movably arranged in direction to said first jaw, said second jaw having a cavity therein,
• a number of hollow needles carried by said second jaw and protruding against said first jaw, said hollow needles being connected with said cavity,
• a drive means arranged on said support structure for moving said second jaw in direction to said first jaw,
• an intermediate means operatively connecting said drive means and said second jaw in a yielding relationship, said intermediate means yielding under increased pressure after said needles having fully penetrated an animal's ear located between said first and second jaws,
• a storage chamber for tatooing liquid and
• a pump chamber comprised by said intermediate means and connected to said storage chamber and said cavity by check valves,
• the volume of the pump chamber being reduced when said intermediate means yields thereby pressing tatooing liquid out of said pump chamber through said cavity and said hollow needles into animal's ear.
