The invention in question relates to a device for the removable securing of a holder (1), especially for a prism (27).When taking geodesic measurements, it is usual to use a rod in the ground, rock, etc. in order to mark polygon points. However, these markings are subject to powerful external and natural influences.The purpose of the invention in question is to indicate a device for detachable securing of a holder (1), for example for a prism (27). According to the invention. the device is characterised by a stationary wall bracket with a projecting stud (23) the end of which passes into a knob (24). A recess (5) in the holder (1) is intended to engage the knob (24). The securing of the holder in position is achieved by the use of adjustment screws (6, 7a, 7b).<IMAGE> |
