[0040] Specifically, first, the staff feeds the fabric to be quilted and embroidered to the position directly below the front row needles 6 and the back row needles 7 on the top of the stand 1 through the transmission component 4, and drives the transmission component 4 and the sewing needle box 5 and the front row needles 6 and the back row needles 7 through the control panel 3, and quilts the fabric according to the route set by the program. However, for some special sewing patterns, the needle spacing needs to be adjusted. Since a connecting plate 11 is provided on one side of each group of front row needles 6 and back row needles 7, when it is necessary to adjust the spacing between the adjacent needles of which group of front row needles 6 and back row needles 7 needs to be adjusted, the control panel 3 is used to find the numbered needles that need to be adjusted, and then the cylinder 121 on the side of the moving block 85 corresponding to the corresponding needle is started, and the cylinder 1 21 drives the housing 122 at the output end, and the housing 122 moves toward the block 1210. The groove 123 opened inside the housing 122 corresponds to the block 1210. Since an extension shell 1211 is provided on both sides of the housing 122, the interior of the extension shell 1211 is a hollow structure, and one end of the extension shell 1211 is open. The open end of the extension shell 1211 is connected to the groove 123 of the housing 122. Since a moving rod 124 is slidably connected to the interior of the extension shell 1211, a limit block 126 is provided at one end of the moving rod 124. The limit block 126 is trapezoidal, and a spring 125 is provided at one end of the limit block 126. One end of the spring 125 is connected to the inner wall of the extension shell 1211. As the housing 122 moves, the block at one end of the fixed column 128 is 1210 enters the interior of the groove 123, the card block 1210 is in the shape of a truncated cone, the inclined surface of the card block 1210 contacts and passes through the inclined surface of the limit block 126, so that the card block 1210 squeezes the two groups of limit blocks 126 to retract into the interior of the extension shell 1211, and the limit block 126 drives the moving rod 124 at one end to slide to the outside of the extension shell 1211, so that the limit block 126 compresses and accumulates force on the spring 125, so that when the limit block 126 contacts the side of the card block 1210 close to the sliding block 129, the limit block 126 is not squeezed, and rebounds and stretches through the spring 125, so that the spring 125 drives the limit block 126 to move into the interior of the groove 123, and the distance between the two groups of limit blocks 126 is less than the maximum diameter of the card block 1210, and further the card block 1210 It is blocked by the limit block 126, so that the card block 1210 is clamped inside the groove 123, so that the moving block 85 is fixed to the connecting plate 11 through the clamping structure 12, and the clamping condition is monitored by the monitoring sensor 10 set on one side of the moving block 85 to see whether the clamping is successful, and then feedback information is sent to the display screen of the control board 3. The connecting plate 11 of the moving block 85 is fixed to the needle head, so that the servo motor 81 is started through the external control board 3, and the servo motor 81 drives the screw rod 1 82 at the output end to rotate, and the screw rod 1 82 drives the screw rod 2 83 at one end to rotate. The screw rod 1 82 and the screw rod 2 83 are set with reverse threads, and the screw rod 2 83 drives the connecting rod 84 at one end to rotate. There are multiple groups of screw rods 1 82, screw rod 2 83 and connecting rod 84.When the connecting rod 84 drives the next set of screw rods 1 82 and screw rod 2 83 to rotate, the screw rods 1 82 and screw rod 2 83 respectively drive the moving block 85 connected by the surface thread to move. At this time, whichever set of needles needs to be adjusted can be fixedly connected by the clamping structure 12. When it is necessary to separate the connecting plate 11 and the moving block 85 through the clamping structure 12, the cylinder 121 is driven toward the side plate 127 for the second time, so that one end of the shell 122 contacts the side plate 127, and the cylinder 121 is driven again to drive the shell 122 away from the side plate 127, so that the cylinder 121 drives the shell 122 to move toward the side plate 127 again, so that the shell 122 drives the limit block 126 inside the extension shell 1211 to move toward the side plate 127 again. The limit block 126 contacts the inclined surface of the sliding block 129 and is squeezed back into the interior of the extension shell 1211. Since the sliding block 129 is truncated and contacts the clamping block 1210 The reverse arrangement is adopted, and the sliding block 129 slides on the fixed column 128. As the housing 122 moves, the limit block 126 first drives the sliding block 129 to move to the bottom of the side plate 127. Then, the limit block 126 slides to the inclined surface of the sliding block 129 close to the side plate 127. As the cylinder 121 drives the housing 122 to move away from the side plate 127, the two sets of limit blocks 126 squeeze and push the inclined surface of the sliding block 129 close to the side plate 127. The sliding block 129 moves away from the side plate 127 and contacts the clamping block 1210, so that the two sets of limit blocks 126 slide across the inclined surface of the sliding block 129, and the limit blocks 126 are squeezed back into the extension shell 1211 by the intersection of the sliding block 129 and the clamping block 1210, so that the thrust limit of the clamping block 1210 is blocked, and the clamping block 1210 and the sliding block 129 are separated from the interior of the groove 123, thereby completing the separation of the connecting plate 11 and the moving block 85;

[0041] The gear 92 is engaged with the screw rod 93 at both ends and is threadedly connected to the sleeve 94 to move. The screw rod 93 is connected to the fixing plate 95 connected by the bearing and the top plate 96. The top plate 96 is connected to the sewing needle box 5, so that the sleeve 94 drives the round shell 131 to move toward the inside of the embedded groove 1315 opened in the connecting plate 11, so that the twist groove barrel 132 first contacts the inside of the embedded groove 1315 and is squeezed, so that the twist groove inside the twist groove barrel 132 is threadedly connected to the twist rod 135, and the tension spring 134 connected to the outer end of the twist groove barrel 132 through the sleeve plate 133 is compressed and stored, and the twist rod 135 drives the driven rod 136 to rotate, and the driven rod 136 drives the rotating disk 137 to rotate, so that the arc-shaped sliding groove 138 distributed on the surface of the rotating disk 137 rotates, and the slider 131 inside the sliding groove 138 9 drives the slide bar 1310 to slide straight outward in the groove 1311 opened on the surface of the cross plate 1312, so that the slide bar 1310 slides in the notch 1313 opened on the surface of the round shell 131 and engages with the embedded groove 1315, and a second magnet block 1316 is symmetrically arranged inside the embedded groove 1315, and a first magnet block 1314 is arranged on the outer end of the slide bar 1310, and the slide bar 1310 engages with the second magnet block 1315 through the first magnet block 1314. 16 opposite poles are attracted and fixed, which is more stable and convenient to lock, and is convenient for the subsequent quilting and embroidery work. On the contrary, the embedded groove 1315 has a certain length, so that the sleeve 94 drives the round shell 131 and the slide rod 1310 to move toward the outer end, so that the magnet block 1314 at one end of the slide rod 1310 is separated from the magnet block 2 1316, so that the twisted groove cylinder 132 is not squeezed and rebounds through the tension spring 134, and the twisted rod 135 is reversed to make the slide rod 1310 return to its position.
