Patent ID: 8608148

Claim:
A tool holder comprising: a base body; a stop element projecting upward from the base body and defining a first stop surface for a tool, wherein the first stop surface lies in a first plane of the tool holder; two guide elements projecting upward from the base body to cooperate with guide sections of the tool, wherein each guide element comprises first and second side pieces, each first side piece extending vertically upward from the base body, each second side piece branching off from the corresponding first side piece at a right angle in such a way that the second side pieces of the two guide elements face each other, wherein the two guide elements enclose a space between them, the space being open to a top and confined by the base body at a bottom; wherein one of the first side pieces defines a second stop surface for the tool, which second stop surface lies in a second plane of the tool holder which is perpendicular to the first plane of the tool holder; wherein one of the second side pieces associated with the one of the first side pieces defines a third stop surface for the tool, which third stop surface lies in a third plane of the tool holder which is perpendicular to the first plane and to the second plane of the tool holder; and a pin, which is recessed into the base body and can be extended from the base body into the space between the guide elements, and which is to be introduced into a receptacle in the tool, wherein the pin comprises a planar slanted active contact surface, which defines a fourth plane, which intersects each of the first, second and third planes of the tool holder at an acute angle, as a result of which the active contact surface, upon extension of the pin, delivers a force component acting toward each of the first, second and third stop surfaces.
