| 摘要 |
The invention relates to a functional component usable for demonstration and/or training purposes which can be releasably secured to the fitting surface of a base (1) and has a securing device engageable with the support (1) to this end. The securing device (8) takes the form of a clamp (11) having at least one clamping component (15) projecting on the underside of the functional component (5) and engaging in a securing recess (3) in the support (1) when fitted on the support (1). By means of an actuator (22) in the clamp (11) it is possible to set the clamping component (15) manually and without the need for tools between a clamped and a released position, whereby, in its clamped position, it is prestressed transversely (16) to the securing recess (3) against the surface of said recess (3) and, in its released position, it acts with reduced prestress against the recess surface or is removed therefrom. |
