Description of the invention (4) = female snail b 'forms a male snail on the periphery of the transfer tone 33 (picture 1 and picture 2). Via the transmission adjustment table 35 fixed to the sewing machine frame μ, the transmission rotation f is broadened to the transmission adjustment shaft 33, and the position of the transmission shaft 35 in the axial direction is adjusted by the transmission adjustment "35". State > _ / According to FIG. I and FIG. 2 ′, a description is given of the first embodiment of the sewing machine's feed volume adjustment device according to the present invention. The transfer regulator 31 has a cam portion 31 a or a convex portion 161 b. It has the same structure as the conventional one. The cylindrical transmission adjusting body 32 is formed with a female bolt 32b in the cylinder. The leading end portion 32a of the transmission adjusting body 32 is provided with a smooth and round shape on a hemisphere. It can be engaged with the cam part 31a or the cam part ^^ In addition, the crocodile slave is integrated at the end after the adjustment body 32 is conveyed, and the crocodile part 32c forms a flat part of the two sides of the disc, …… On the other hand, in the frame of the machine, “holes Fb that can move forward and backward and keep the cross section of the cross-section adjustment body 32 are formed. In the second figure, the two side walls Fb of the hole Fb, and Fb The plane is formed on the plane portion which can be slidably connected to the transmission adjusting body 32. Therefore, the transmission adjustment Even if the joint shaft 33 is rotated to advance and retreat the conveying adjusting body 32, the conveying adjusting body% will not rotate. On the outer periphery of the conveying adjusting shaft 33, a male bolt 3 that is screwed to the conveying adjusting body 32 and a Shen Zhixiong bolt 33a are formed. The rear end of the shaft 33 124322 0_ B7 V. Description of the invention (5 / unit, the integrally formed part 33b 'for preventing disengagement goes further, and the end forms an opening bolt hole 33c.… Fixed to the sewing machine frame F transmission adjustment The stage 35 is pressed against the crocodile portion 33b of the transmission adjustment shaft 33 so that it will not be separated from the sewing machine frame 形成. A differential hole 35a is formed at the rear end of the transmission adjustment shaft 33 at the center. The transmission adjustment shaft 33 is inserted at the upper end. The hole adjustment of the transmission adjustment table, the wave seat 37, and the gasket 36 'are integrated with the conveying turntable by bolts 38. The gasket 36 is an object to protect the end face of the conveying turntable 34, and the wave seat is to stop slowly. In this way, since the transfer adjustment shaft 33 and the transfer turntable 34 are integrated through the transfer adjustment table support, the transfer adjustment shaft 33 is not only easy to be pulled out when the crotch 33b is engaged with the transfer adjustment table 35, but its assembly is also quite simple. Also, in teleport Opposite sides of the joint shaft 33 and the conveying turntable 34 are formed with fine radial recesses & so as to prevent slack after integration. The employee consumer cooperative of the Bureau of Intellectual Property of the Ministry of Economic Affairs prints the conveyance thus constituted. In the volume adjustment device, after the transfer dial 34 is rotated, the integrated transfer adjustment shaft 33 is rotated. The female bolt 32b is screwed to the transfer adjustment body 32 of the male bolt 33a of the transfer adjustment shaft 33, because of its flat portion 32c and the wall surface. Fb restricts the rotation of the rotating shaft, so the hole FB of the sewing machine frame F moves forward or backward with the rotation of the transfer adjustment shaft 33. The distance between the tip 32a and the cam portion 313 or cam portion 31b of the transfer adjuster 31 changes. , The change of the tilt angle of the conveying regulator 31 'causes the cloth feeding amount of the pusher teeth to change. In the thus-configured feed adjustment device of the present invention, the paper size iS is based on the conventional paper size (CNS) A4 (⑵ × 297)

By the narrow electromagnetic spiral, the knocking sound of the automatic reverse mechanism is significantly reduced. . Furthermore, no bolts are formed on the outer periphery of the conveying adjustment body 32, and the carbonized state with the cylindrical portion of the sewing machine frame is exposed over a slightly full length, so that vibration resistance is formed, and the feeding of the sewing machine when running is almost free occur. It is printed by the Consumer Cooperative of the Ministry of Economic Affairs of the Ministry of Economic Affairs of the People's Republic of China 1243220 V. Description of the Invention (6) Next, the second embodiment of the present invention will be described in the third figure. Since this device is basically the same as the first embodiment, the same symbols are assigned to components having the same function, and only the differences will be described. This feed amount adjusting device differs from the first embodiment in that the transfer adjusting body 32 forms a female bolt 32d on its outer periphery, and on the other hand, the transfer adjusting shaft 33 is cylindrical 'and forms a female bolt 33c on its inner periphery. By the formation of the male bolt 32d, the middle portion of the crotch portion 32c of the transfer adjustment body 32 is formed, and the bolt formation portions of the transfer adjustment body 32 and the transfer adjustment shaft 33 become shorter than those of the first embodiment. In addition, the present invention is not limited to the above embodiments, and various changes can be made. For example, instead of integrally including the cam portions 31a and 31b that change the forward and reverse transmission amounts, the forward and reverse cam members are individually set to correspond to the respective cam members, and the third embodiment is provided by Or the conveyance adjusting body and the conveying adjusting shaft of the second embodiment, etc., the forward conveyance amount and the reverse conveyance amount can be adjusted separately. < Effect of the invention > As described above, the feed volume adjustment device of the sewing machine of the present invention is adapted to the Chinese National Standard (CNS) A4 specification (210 X 297 public love) from this paper size

9 五、發明說明（7 ) 於可以以極小的力量無階段的進行送布的調節，所以送 布量的微調整變得容易，進而提昇縫製的品質。另外， 亦可以明顯的降低自動倒退機構作動時之敲打聲。 在傳送调節體形成雌螺栓、傳送調節軸形成雄螺栓 的場合，由於傳送調節體以略前長得到與縫紉機框架崁 合狀態，形成耐振性高的物體，因而幾乎不會發生縫紉 機運轉時送布錯亂之問題。 由於介由傳送調節台使傳送調節台軸與傳送轉盤一 體化，所以不僅不容易由縫紉機框架拔出，裝配上亦相 當簡單。 〈圖面的簡單說明&gt; 第1圖為構成本發明之第i實施形態之傳送調節體部 之各零件之分解透視圖。 第2圖為本發明之第丨實施形態之圖，（以裝配狀態 之面圖，⑵為構成傳送調節體部之各零件之分解側面 圖’⑶為說明縫切機框架筒狀部與傳送調節體之關係之9 V. Description of the invention (7) Since the feeding can be adjusted steplessly with very little force, the fine adjustment of the feeding amount becomes easy, thereby improving the quality of sewing. In addition, the rattling sound of the automatic reverse mechanism can be significantly reduced. When the transfer adjustment body forms a female bolt and the transfer adjustment shaft forms a male bolt, the transfer adjustment body becomes a state of being engaged with the sewing machine frame a little longer, forming an object with high vibration resistance, so almost no feeding occurs when the sewing machine is running. Disorganized problem. Since the shaft of the conveying adjusting table and the conveying turntable are integrated through the conveying adjusting table, it is not only difficult to pull out the sewing machine frame, but also the assembly is relatively simple. <Brief Description of the Drawings> Fig. 1 is an exploded perspective view of parts constituting the transfer regulating body of the i-th embodiment of the present invention.
