[0048] Among them, the core feeding assembly 321 sewing machine head 3 includes a guide sleeve 3211, a ratchet 3212 sewing machine head 3 and a plunger 3213. The guide sleeve 3211 is arranged on the sewing machine head 3 and is located at the upper end of the sewing machine head 3. The guide sleeve 3211 sewing machine head 3 is threadedly connected with the sewing machine head 3. The specific threaded connection method is that the guide sleeve 3211 sewing machine head 3 has a threaded section along the outer peripheral wall, and the upper end of the sewing machine head 3 corresponds to the threaded section and is penetrated by a threaded hole. The threaded section sewing machine head 3 is threadedly connected to the threaded hole to realize the connection of the guide sleeve 3211 sewing machine head 3. The guide sleeve 3211 sewing machine head 3 is provided with a locking sleeve 35, and the locking sleeve 35 is sleeved on the position of the guide sleeve 3211 sewing machine head 3 corresponding to the threaded section 13 sewing machine head 3, the locking sleeve 35 sewing machine head 3 is threadedly connected with the guide sleeve 3211 sewing machine head 3, the locking sleeve 35 sewing machine head 3 is rotated along the thread direction of the threaded section 13 sewing machine head 3 and then tightened, the locking sleeve 35 sewing machine head 3 is pressed against the upper end surface of the sewing machine head 3, thereby improving the positioning stability of the guide sleeve 3211 sewing machine head 3.

[0049] During adjustment, the user drives the rod core 31 to slide to compress the spring member 322. A positioning structure for positioning the rod core 31 to slide is provided in the guide sleeve 3211. The rod core 31 is pressed down by pressing the rod core 31 and the rod core 31 is positioned through the positioning structure. When the rod core 31 is pressed down, the spring member 322 is in a compressed state, that is, the pressure adjustment assembly is in the second adjustment position; the pressure of the presser rod 33 is increased by compressing the spring member 322, thereby increasing the pressure of the presser foot 34, so that the presser foot 34 can press the fabric to adapt to the user's manual sewing during manual sewing; the user can press the rod core 31 again to reset the rod core 31, thereby releasing the spring member 322, that is, the pressure adjustment assembly is in the first adjustment position, to reduce the pressure of the presser rod 33 and the presser foot 34, so as to adapt to the template sewing of the sewing body 1. The cloth feeding drive mechanism described in this patent is the same as the cloth feeding mechanism of the existing sewing machine, and a stepper motor can also be configured separately to feed cloth; the cloth feeding drive mechanism is not required to work in the template sewing state. The cloth feeding drive mechanism can also be a cloth feeding tooth fixed in the sewing machine head 3. When the sewing mode of the template sewing machine is switched to the flat sewing machine mode, the user needs to install the cloth feeding drive mechanism in the sewing machine head 3, replace the presser foot adapted to the flat sewing mode, and drive the rod core 31 to put the presser foot assembly in the first adjustment state to achieve mode switching.

[0050] After the template sewing machine in this patent is switched to the lockstitch sewing machine mode, the presser foot rod 33 is driven by different lifting and pressing components 61 accordingly. Figure 5 , 6As shown, the lifting and pressing assembly 61 includes a first lifting and pressing motor 62, the first lifting and pressing motor 62 drives a first connecting rod assembly 63, the first connecting rod assembly 63 is connected to a fixing block 64, and the presser foot rod 33 is connected through the fixing block 64. The first lifting and pressing motor 62 is used to drive the presser foot rod 33 to lift when the template is sewing. The first lifting and pressing motor 62 is a stepping motor, and the first connecting rod assembly 63 can adopt an existing crank connecting rod structure; when the first lifting and pressing motor 62 is working, it drives its rotating shaft to rotate, and the rotation of the rotating shaft drives the fixing block 64 fixed on the presser foot rod 33 to move, so as to drive the presser foot rod 33 to lift or press down.

[0051] The lifting and pressing assembly 61 includes a second lifting and pressing motor 71, which drives a second connecting rod assembly 72, which drives a top block 73; a sliding hole 641 is provided in the fixed block 64, and the first connecting rod assembly 63 includes a sliding pin 631 slidably arranged in the sliding hole 641; the top block 73 is used to lift the fixed block 64 to lift the presser foot rod 33, and a reset member 642 is also provided in the sliding hole 641 to give the fixed block 64 a tendency to move in the direction of pressing the presser foot rod 33. Figure 6 As shown, the second lifting and pressing motor 71 and the second connecting rod assembly 72 are arranged in the sewing machine head 3, the second connecting rod assembly 72 is a pull rod structure, the top block 73 is triangular, one end of the pull rod is connected to one end of the top block 73, and the other end is located below the fixed block 64. The second lifting and pressing motor 71 is used to lift the presser foot during manual sewing. This is because during manual sewing, the pressure of the presser foot rod 33 becomes larger, and the first lifting and pressing motor 62 cannot meet its lifting and pressing requirements. Therefore, the second lifting and pressing motor 71 is independently arranged, and the second lifting and pressing motor 71 lifts the fixed block 64 with the sliding hole 641 to drive the presser foot rod 33 to rise, and the reset is achieved by pressing down the reset member 642, and the reset member 642 is generally a spring.

[0052] To sum up, the sewing machine in this patent realizes the switching of the template sewing machine to the flat sewing machine mode through the pressure adjustment of the presser foot 34 and the disassembly and assembly of the extension plate 5 to meet the user's template sewing needs and manual sewing needs, and increase the flexibility of the use of the sewing machine; by setting the pressure adjustment component, the transformation process of the template machine into a flat sewing machine is greatly simplified, and the user only needs to replace the presser foot 34 and the needle plate, and then install the feed dog; the above steps are actions that sewing workers can complete relatively easily.

[0053] Furthermore, two sliding grooves 21 are provided, each of which is provided with a first sliding member 41, and the two first sliding members 41 are respectively connected to the left and right ends of the second sliding member 42 through a sliding connecting frame 43. The movement stability of the second sliding member 42 can be increased by the two first sliding members 41 provided on the left and right.

[0054] Furthermore, a "U"-shaped sliding support frame 44 is provided on the lower end surface of the workbench 2, the first sliding member 41 is located in the sliding support frame 44, and both ends of the sliding support frame 44 are connected to the workbench 2. Figure 3 , 4 As shown, connecting holes are provided on both ends of the sliding support frame 44, and the installation of the sliding support frame 44 is achieved by arranging fasteners connected to the workbench 2 on the connecting holes. A connecting hole is also provided in the sliding support frame 44, and fasteners connected to the first sliding member 41 are arranged in the connecting hole to achieve the installation of the sliding support frame 44 and the first sliding member 41. The overall installation structure is compact, which is convenient for the quick assembly of the first sliding member 41.

[0055] The above embodiments are only preferred embodiments of this patent and are not intended to limit the protection scope of this patent. Therefore, any equivalent changes made based on the structure, shape, and principle of this patent should be covered within the protection scope of this patent.
