and the slit 21a, the secondary needle support cylinder 2
1 are rotated together. Then, as shown in FIG. 6, the intermediate lever 73 is rotated counterclockwise through the engagement between the forked portion 77 of the secondary needle support cylinder 21 and the linking pin 73a of the intermediate lever 73. Rotation of the support cylinder 21 and the sub needle 73a is allowed, and the connection between the hook 24a of the sub needle 24 and the hook 4a of the main needle 4 is released. Next, in this state, if the secondary needle 24 is pulled forward by an appropriate amount within the support tube 21,
Since the needles 4 and 24 are separated from each other, operations such as stitch adjustment can be easily performed. In this case, in this embodiment, since both attachment operation protrusions 26 are formed to protrude in a direction perpendicular to the axis of the secondary needle 24, it becomes easy for the user to grip the protrusions 26, and when the connection is released. Improves operability.

After replacing the secondary needle 24 and resolving the trouble in this manner, the operation lever 27 is rotated to the holding position and its linking portion 27b is locked in the locking recess 26a of the mounting operation protrusion 26. , the secondary needle 24 is attached and held to the secondary needle support cylinder 21. Next, when the sub cover 51 is rotated clockwise in the state shown in FIG.
2, the support member 42 is rotated integrally with the sub cover 51, as shown in FIG.
The sub cover 51 is held in the covering position by the hook 52b of the push button 52 and the hook 53 of the main cover 6, and the support member 42 is held in a horizontal position by the sub cover 51, so that the knitting The holding member 47 is arranged at the operating position. Therefore, in this case as well, similarly to the opening operation of the sub-cover 51, the operation of returning the knitted fabric presser member 47 to the operating position can be easily performed with one touch. Moreover, in this embodiment, since the knitted fabric presser member 47 is held in the operating position by the sub-cover 51 via the support member 42, there is no means for independently locking the support member 42 to a part of the carriage 5. is no longer necessary, and the structure of the knitted fabric presser device becomes simpler.

Effects As detailed above, this invention is particularly advantageous in that the opposing needle 24 is integrally provided with the engaging portion 26a, while the carriage 5 is provided with a support member 21 that removably supports the opposing needle 24. It is movable between a holding position where it engages with the engaging portion 26a and holds the facing needle 24 on the support member 21, and a release position where it dissociates from the engaging portion 26a and releases the holding of the facing needle 24. The present invention is characterized in that a holding member 27 is provided.

Therefore, by moving the holding member 27 between the holding position and the release position, the opposing needle 2
4 can be easily and quickly attached to, detached from, and replaced with the support member 21, and when a problem occurs, work such as releasing the connection between hooks of opposing needles and knitting needles can be easily and quickly performed. or,
By supporting the opposing needle 24 on the support member 21 and arranging the holding member 27 at the holding position, excellent effects such as being able to reliably hold the opposing needle 24 are achieved.
