Description of the Invention (7) Because the front end of the manual operating body 17 is engaged with the groove 3 d of the second eccentric cam member 3, the second eccentric cam member is blocked 3 of free rotation. At the same time as when the manual operating body 17 is pressed, the front end portion of the stopper body 10 pushes the other end 10 b of the stopper body 10, so the stopper body 10 is also in the groove by resisting the potential spring pressure of the torsion spring 13. 3 The sliding movement is in the direction of the counter-arrow A, and the stopper portion 10a is separated from the stopper wheel 2b. Therefore, the first eccentric cam member 2 is freely rotatable with respect to the second eccentric cam member 3. In this state, for example, when the main shaft 1 is manually rotated, the first eccentric cam member 2 fixed to the main shaft 1 is rotated. This rotation is possible within a range in which the stopper pin 2 C is stopped by the stopper pin 3 f of the second eccentric cam member 3 which is fixed to be non-rotatable by the manual operation body 17. As a result, as shown in FIG. 2, the rotational position of the first eccentric cam 2 a with respect to the second eccentric cam 3 b is adjusted, and the position of the lever 14 with respect to the axis of the main shaft 1 can be changed. • The stop pin 3f of the second eccentric cam structure 3 and the stop pin 2c of the first eccentric cam member 2 define the relative rotation range of the first and second eccentric cams 2a and 3b, but the relative rotation range is Appropriately decided with purpose. That is, when the above-mentioned eccentricity adjustment device is applied to a crimping sewing machine, the combination of the first and second eccentric cams 2a, 3b forms a combined eccentricity, and the purpose of excluding the combination of actions that are not related to the forward and backward movement of the tooth is excluded. And to prevent the timing of the action with the needle, specifically, when the transfer tooth protrudes, it is controlled so that the needle is always located at the upper part to prevent the needle from colliding with the transfer tooth and breaking, to determine the stop pin 2 c fixed At the position of the first eccentric cam member 2 and the stopper pin 3 f The paper size is suitable for financial affairs (CNS) Α4 · (21GX297 mm) — L ..

Description of the invention (8) Fixed at the position of the second eccentric cam member 3. In the above-mentioned embodiment, the positions of the stop pins 2 c and 3 f are such that the first eccentric cam 2 a is relatively rotated to the right with respect to the second eccentric cam 3 b, and can be rotated about 45 degrees to the left respectively. . The eccentric amount adjusting device of the above embodiment is used for adjusting the amount of movement of the feeding teeth of the hemming seam sewing machine, but the use is not limited to those who use the hemming sewing machine. Of course, it can also be used for movement or stroke. The adjusted device β [Effect of the invention] As can be seen from the above description, in the eccentricity amount adjustment device described in the first patent application scope of the present invention, the structure of the eccentric convex transmission mechanism becomes compared with the conventional structure. It is simple. The number of parts is reduced, and as a result, it is less likely to cause a fitting shake, and it is excellent in durability. The adjustment torque is lighter and easier to adjust. Moreover, in the eccentricity amount adjustment device described in the second item of the scope of the patent application, the stopper body 2 is formed by forming a stop wheel 2 b on the eccentricity of the eccentricity of the first eccentric cam 2 a and changing the eccentricity. The stopper portion 10a on the side is a stopper wheel 2b that is often stopperable and integrally formed on the first eccentric cam 2a. Further, in the eccentricity adjustment device described in item 3 of the scope of patent application, in a state where the second eccentric cam member is prevented from rotating by a manual operation body, the first eccentric cam is connected to the first stopper pin by a manual operation body. The second eccentric cam is rotatable within the range up to the second stopper pin, so it is appropriate (please read the precautions on the back ^^ write this page). • Binding.
