Punch device for marking drilled holes

Punch device with a marking element for marking drilled holes to be applied with positional accuracy for the purpose of the positionally accurate positioning of an object to be attached to a wall, wherein:

• the marking element is transferable reciprocally from a first position, in which the marking element is arranged remotely from the wall, into a second position, in which a front part of the marking element close to the wall makes contact with a point on the wall for the purpose of producing a mark;
• the marking element is at least partially reciprocally mounted inside a housing, which is provided with a front positioning element provided with a central opening close to the wall for positioning the punch device on the wall, as well as with a mounting element provided with a drilled hole for mounting a supporting element connected to the marking element, which has a means for the releasable attachment of the mounting element to the housing;
• the supporting element connected to the marking element is transportable from a first position, in which the marking element is at least partially arranged inside the housing, into a second position, in which at least a front part of the marking element close to the wall is led through the central opening of the positioning element and protrudes from the housing for the purpose of contacting a point on the wall;
• the supporting element is preloaded in the first position by means of a spring device interacting with a rear surface of the positioning element and is transferable into the second position by pressing the supporting element against the force of the spring device;
• the supporting element is of bolt-shaped configuration;
• and
• the marking element is securely connected to the supporting element in the region of a front-end face of the supporting element close to the wall.
