Is provided. As the driving means, an appropriate device that moves linearly, and in the embodiment shown in the figure, an air cylinder is used. However, a solenoid, a motor cylinder, and other actuators can be used as appropriate. This driving means (6) Preferably, the mounting position can be adjusted by moving the mounting base (7) back and forth along the base plate (3).

  The stamp link (5) is configured by connecting two link plates (8) and (8) in an opposing state with a space therebetween, and on the base end side, a drive shaft of the drive means (6) is formed. By providing the mounting shaft (10) for connecting (9), the whole is compactly formed. An arm (12) is pivotally attached to the pivot (11) provided at the intermediate portion of the stamp link (5), and the other end of the arm (12) is a pivot (13) provided on the pivot support (4). The arm (12) is pivotable about the pivot (13) of the shaft support (4). As shown in FIGS. 3 and 4, the arm (12) can be rotated (oscillated) within a predetermined range, and in other words, at the start and end of the rotation range, in other words, the stamp link (5). The stamp link (5) descends in the direction approaching the support base (1) in the figure at the retracted position and the forward position, and rises in the direction away from the support base (1) during movement.

  A stamp portion (14) is provided at the tip of the stamp link (5). The stamp portion (14) can be formed in an appropriate structure having a marking surface (15) on the lower surface in the drawing. The stamp base (14) shown in FIG. 1 fixes the said marking surface (15) to the lower surface of the substantially L-shaped board | substrate (17) which has a standing piece (16) via elastic members (17), such as rubber material. The substrate (17) is inserted into the receiving grooves (21) of the side plates (20) and (20) until the inner surface of the standing piece comes into contact with the stamp body (19), and the cross section of the standing piece (16) is almost inverted. One side of the U-shaped presser plate (22) is applied and fixed with a thumbscrew (23). If the thumbscrew (23) is loosened and the holding plate (22) is moved, the substrate (17) can be removed from the receiving groove (21) of the side plate (20) and replaced with a substrate having another marking surface. it can. The holding base (24) for holding the stamped material such as rubber hoses and the substrate (17) are connected with an appropriate length connecting wire, chain or other connecting tool (25) as shown in FIG. In this case, the holding base (24) for holding a predetermined rubber hose and the substrate (17) corresponding to the holding base (24) can be always combined together, so that no poker misses can occur.

  FIG. 7 shows another embodiment of the stamp portion (14). A substrate (26) having a marking surface (15) is provided at the lower end of the support shaft (27), and the support shaft (27) is provided on the stamp portion main body (28). ) And a retaining nut (29) is provided at the upper end to hold the substrate so that it can be raised and lowered. A spring (30) is provided between the substrate (26) and the stamp portion main body (28) so as to urge the substrate (26) downward in the drawing so as to alleviate the impact.
