Device for stretching skin

A device for stretching skin, comprising

• a plate-shaped main body;
• a tensioning element arranged on said main body, said tensioning element being rotatable about an axis of rotation, such that a pulling thread affixed on said tensioning element is configured to be wound up on said tensioning element and tensioned;
• a latching lock for fixing said rotatable tensioning element and preventing inadvertent release of said tensioning element;
• and
• a securing lever arranged on said tensioning element, said securing lever being movable both around said axis of rotation and in a direction of said axis of rotation;
• wherein said tensioning element is able to be moved in the direction of said axis of rotation against a force of a spring which causes said latching lock to be removed from a latching position,
• wherein when said tensioning element is released, said latching lock can be returned to said latching position as a result of said force from said spring, and
• wherein said latching lock and a movement of said tensioning element can be actioned by said securing lever at a same time,
• wherein said securing lever is configured to be actioned in
• a first position where said securing lever is raised from said tensioning element and is not secured,
• a second pivoted down position where said securing lever blocks a movement of said tensioning element in said direction of said axis of rotation, and
• a third position which prevents said securing lever from raising upwards, where said securing lever can, from said second pivoted down position, be laterally displaced relative to said axis of rotation into said third position.
