The spring-biased pressure pin has a shaft (10) surrounded by a sleeve (14) and which fits into a head (1). The head has two recesses (6) in the shape of part of a circle and there are curved lugs (21, 22) at the top of the sleeve which fit into these. A spring (18) is mounted around the shaft in a bore (17) in the sleeve, below the lugs. |
