Field of the Invention The present invention relates to a parallel sewing machine, and more particularly to a parallel sewing machine and a cloth edge cutting transmission device thereof. [Previous technique J is relatively rare compared to the general sewing. The main reason is that the two pieces of fabric are overlapped and then sewn. The width of the two pieces of fabric must be the width of the sewing machine. In order to ensure that the stitching is sewn in the overlapped area', the width of the fabric overlap is often required to be worn by the operator before the fabric is fed into the presser foot; however, this method of work depends on the operator's seam. Experience and proficiency, and on the market: a wide variety of sewing machines. 'There are different adjustment methods for different types of machines. Therefore, even the experienced operators can not adjust the width and sewing of the fabric. The width is equivalent.

The sentence component 831 is sleeved on a hollow pin shaft 832 and connected by a hook eccentric 8311 of the spindle 82 and connected to the eccentric wheel 8311 and rotated by the hook eccentric 8311. A linkage member 8313 of the needle rocker arm 8312, the linkage member 8313 follows the hook rocker arm 8312 for reciprocating rocking. The hollow horizontal axis 832 is pivotally connected to the inside of the upper body 81 through a sleeve and is disposed parallel to the main shaft 82, and is driven to rotate reciprocally by the linkage 83. The hook link 833 is fixed to the hollow horizontal axis 832 and the other end is connected to the hollow longitudinal axis. 099104240 Form No. A0101 Page 8 of 27 0992007937-0 201128014 834. The hollow longitudinal axis 834 is disposed substantially orthogonal to the hollow horizontal axis 831, and is connected to the hook link 833 through the short rod, thereby generating reciprocating rotation by reciprocating swing of the hook link 836. . The hook set 8 3 5 is connected to the lower stage of the hollow longitudinal axis 834 and reciprocally oscillates following the reciprocal rotation of the hollow longitudinal axis 834. [0012] Referring again to the first figure, the presser 84 mainly includes a pressing rod 841 and a parallel pressing foot 842. The pressing rod 841 is located adjacent to the hollow longitudinal axis 834 and penetrates through the Ο [0013] bushing. The upper body 81 and the squeezing foot 842 are attached to the bottom end of the pressing rod 841. Referring to the second to seventh illustrations, the edge trimming transmission device 1 of the present invention includes a transverse drive shaft 10, a drive assembly 2〇, a longitudinal crankshaft 3〇, a link 40, and all the cutter sets 5 One to move the arm 6.; [0014] The transverse drive shaft 10 is an elongated rod having a length greater than the length of the hollow transverse shaft 831, and is disposed parallel to the main shaft 82, after the transverse transmission shaft 10 passes through the hollow transverse shaft 831 The south end portion protrudes outside the hollow horizontal axis 831, respectively. [0015] The driving assembly 20 mainly includes an eccentric wheel 21, a rocker arm 22 and a linking member 23. The eccentric wheel 21 is sleeve-fixed on the main shaft 82 and rotates together with the main shaft 82, and the end portion of the rocker arm 22 is sleeved. The other end of the eccentric wheel 21 is connected to the linking member 23, and one end of the linking member 23 is sleeved and fixed on the end of the lateral transmission shaft 1 〇 protruding from the hollow horizontal shaft 831; thereby, the rotation of the main shaft 82 and the eccentric wheel 21 is utilized. The rocker arm 22 and the linking member 23 are caused to reciprocately swing. The longitudinal crankshaft 30 is composed of a first shaft 31 and a second shaft 32 which are parallel but different center lines, wherein the length of the second shaft 32 is greater than the hollow longitudinal 099104240 Form No. 1010101 Page 9 of 27 0992007937-0 [0016] 201128014 The length of the pumping 832, and its parallel pressing rod 841 is arranged in the second shaft after the second shaft is pierced into the hollow longitudinal side 2, and the bottom end portion thereof is convexly exposed to the hollow longitudinal axis of the milk outer rigid link 40- The end is protruded from the end of the hollow horizontal shaft 831 through the screw (4) in the lateral transmission (4), and is interlocked with the transverse transmission shaft 1〇, and the other end is connected to the first shaft 31 of the longitudinal crankshaft 30 through a short rod 33.
