| 摘要 |
The invention relates to a support and guide assembly for a rod which can perform an axial reciprocating movement. The inventive assembly comprises a tubular structure (4) which is formed by two opposing co-axial tubular walls (1, 2) which are joined by two or more radially-extending longitudinal ribs (11). The aforementioned tubular structure houses linear guide means for a rod (3) which is actuated by an actuating assembly (17) that is connected to a support structure (13) in order to perform an axial reciprocating movement. The assembly comprises a joint which rotates the rod (3) in relation to the actuating assembly (17), means for pivot fixing the tubular structure (4) to the support structure (13) and rotation coupling means for coupling the rotation of the tubular structure (4) to the rotation of the rod (3), thereby enabling the axial reciprocating movement of the rod (3). |
