Abstract
A device for the implementation of pellets containing medication in animals comprises a housing in the shape of a pistol with a handle, a hollow needle for injecting the body of the animal arranged at the front side of the housing and a push rod adapted to being slid into the hollow needle and supported by the housing so as to be longitudinally displaceable. A shaft is also provided in the housing before the hollow needle for a magazine holding pellets which is displaceable therein. A longitudinally displaceable press-back device is arranged in the housing parallel to the push rod and hollow needle. A drawing mechanism is included in the housing for moving the push rod and press-back device. The mechanism is able to be set in motion by an operating lever fastened at the handle via a toothed segment coupled with the operating lever and via a toothed wheel engaging with the operating lever. The driving mechanism has a continuous toothed belt which is guided along a predetermined region of its length parallel to the push rod between two deflecting rollers and via a toothed belt pulley. The pulley is connected coaxially with the toothed wheel. The continuous toothed belt has a clamping…
