DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] Please refer to Figures 1-4, the present utility model provides the following technical solutions: It includes an operation platform 1. A sewing groove 11 is formed inside the operation platform 1. A guiding frame 12 is fixedly connected to the bottom end of the operation platform 1. A left-side adaptation bin 2 and a right-side constraint bin 3 are detachably connected inside the operation platform 1. The left-side adaptation bin 2 and the right-side constraint bin 3 are respectively located on both sides of the sewing groove 11. A positioning block 31 is slidably connected inside the right-side constraint bin 3. A knife sheath 32 is installed inside the right-side constraint bin 3. A knife body 33 is slidably connected inside the knife sheath 32. Two clamping blocks 34 are slidably connected inside both the left-side adaptation bin 2 and the right-side constraint bin 3. A connecting rod 35 is fixedly connected to one side of the positioning block 31, the knife body 33, and the clamping blocks 34. A connecting inclined block 36 is fixedly connected to one side of a plurality of connecting rods 35. A driving rod 4 is provided below the operation platform 1. The driving rod 4 slides inside the guiding frame 12. Two driven extension rods 41 are fixedly connected to both sides of the driving rod 4. A plurality of touch rods 42 are fixedly connected to the top ends of the two driven extension rods 41.
[0017] In this implementation: The operating platform 1 is used to support and connect various components, as well as support the sewing machine. Thus, through the cooperation of other components, the sewing of fabrics and the cutting of sewing threads are completed. The sewing groove 11 opened inside the operating platform 1 is used to make space for the operation of the sewing machine, so that the sewing thread can be located inside the sewing groove 11 and the sewing operation of the fabric can be completed by the sewing machine. A right-side constraint bin 3 is detachably connected inside the operating platform 1. A positioning block 31 slides inside the right-side constraint bin 3. The positioning block 31 is used to constrain and position the position of the sewing thread. There is a slot inside the positioning block 31, and the width of the slot gradually shortens. When the positioning block 31 slides, it will move to the outside of the sewing thread, and the sewing thread will be located in the middle of the positioning block 31 through the guidance of the slot. A knife sheath 32 is also installed inside the right-side constraint bin 3. The knife sheath 32 is used to support the knife body 33, so that the knife body 33 can move horizontally. When the knife body 33 moves horizontally, it will contact the sewing thread and apply a certain pressure to the sewing thread, thereby completing the tangent operation of the sewing thread. Two clamping blocks 34 slide inside both the left-side adapter bin 2 and the right-side constraint bin 3. The vertical heights of the two clamping blocks 34 are respectively above and below the knife body 33. Since the position of the sewing thread has been positioned by the positioning block 31, when the two clamping blocks 34 inside the left-side adapter bin 2 and the right-side constraint bin 3 slide horizontally and approach each other, they will contact both sides of the sewing thread and fix the sewing thread. At this time, when the knife body 33 contacts the sewing thread, since the sewing threads at the upper and lower positions of the cutting position are both fixed, the sewing thread will not move, thereby avoiding situations such as pulling and traction of the sewing thread when cutting the sewing thread. Connecting rods 35 are fixed to one side of the positioning block 31, the knife body 33, and the clamping blocks 34. The connecting rods 35 fixed to one side of several clamping blocks 34 are misaligned in position, and the connecting rods 35 fixed to one side of the positioning block 31 and the knife body 33 are in corresponding positions. When a worker needs to perform a cutting operation on the sewing thread, the worker can slide the active rod 4 vertically upward. The active rod 4 slides inside the guide frame 12. The guide frame 12 will guide the movement of the active rod 4, so that the active rod 4 can stably move vertically upward. Two driven extension rods 41 are fixed to both sides of the active rod 4. Several touch rods 42 are fixed to the tops of the two driven extension rods 41. The several touch rods 42 fixed to the tops of the two driven extension rods 41 are respectively used to drive components such as the positioning block 31 inside the left-side adapter bin 2 and the right-side constraint bin 3 to move. The several touch rods 42 are misaligned, and one of them has a different height. When the worker inserts the touch rod 42 into the right-side constraint bin 3, the touch rod 42 will first contact the connecting inclined block 36 on one side of the positioning block 31. The surface of the touch rod 42 contacting the connecting inclined block 36 is an inclined surface, so that the connecting inclined block 36 will drive the positioning block 31 to move through the connecting rod 35 until the constraint and positioning operation of the sewing thread is completed. Then when the touch rod 42 continues to be inserted into the right-side constraint bin 3,Among them, due to the different heights of the two touch rods 42, the two touch rods 42 can simultaneously contact the connecting inclined blocks 36 on one side of the two clamping blocks 34, thereby driving the two clamping blocks 34 to move, completing the clamping and fixing work of the sewing thread. When one of the touch rods 42 continues to move, it will contact the connecting inclined block 36 on one side of the tool body 33, so that the tool body 33 will slide out from the inside of the tool sleeve 32 to contact the sewing thread, thereby completing the thread cutting operation of the sewing thread. And due to the fixation of the clamping block 34, the sewing thread will not be pulled during the thread cutting operation.,
[0018] A blocking plate 13 slides on one side of the operation platform 1, and a mounting seat 14 is fixedly connected to the top end of the operation platform 1; the blocking plate 13 sliding on one side of the operation platform 1 is used to block the driving rod 4, so as to avoid accidental contact with the driving rod 4 during the sewing operation of the staff and prevent the driving rod 4 from moving. The mounting seat 14 fixed to the top end of the operation platform 1 is used to connect and fix the sewing machine. The staff can fix the sewing machine to the mounting seat 14 by bolts or other means, and then complete the sewing operation of the fabric.,
[0019] A guiding groove 15 is formed on one side of the operation platform 1, and the blocking plate 13 is slidably connected to the operation platform 1 through the guiding groove 15; the guiding groove 15 formed on one side of the operation platform 1 is used to guide the sliding of the blocking plate 13, so that when the staff does not need to perform the thread cutting operation, the blocking plate 13 can be slid to a position corresponding to the guiding frame 12 to block the driving rod 4. When the staff needs to perform the thread cutting operation, the blocking plate 13 can be slid to other positions, exposing the driving rod 4 to the outside, so that the staff can vertically slide the driving rod 4 and drive other components through a plurality of touch rods 42, and then complete the thread cutting operation of the sewing thread.,
[0020] Auxiliary blocks 37 are fixedly connected to the bottoms of a plurality of connecting inclined blocks 36, and a return spring 38 is fixedly connected between each of the auxiliary blocks 37 and the left adaptor bin 2 or the right restraint bin 3; the auxiliary blocks 37 fixed to the bottoms of the connecting inclined blocks 36 are used to assist in guiding the movement of the connecting inclined blocks 36, and the return springs 38 fixed between each of the auxiliary blocks 37 and the left adaptor bin 2 and the right restraint bin 3 are used to drive the plurality of auxiliary blocks 37 to return to their original positions. When the touch rod 42 drives the connecting inclined block 36 to slide, the connecting inclined block 36 will drive the auxiliary block 37 to move synchronously, so that the return spring 38 is compressed and stores energy. When the thread cutting operation is completed, the staff can move the driving rod 4 vertically downward to cancel the limit of the touch rod 42 on the connecting inclined block 36. At this time, the return spring 38 will drive the auxiliary block 37 and the connecting inclined block 36 to move through elastic release of the acting force, so that components such as the positioning block 31 move to their original positions, preventing obstacles to the subsequent sewing operation of the staff.,
[0021] There are a number of alignment slots 39 provided inside both the left - hand fitting bin 2 and the right - hand restraint bin 3, and a number of touch rods 42 slide inside the respective alignment slots 39. The number of alignment slots 39 provided inside the left - hand fitting bin 2 and the right - hand restraint bin 3 are for making space for the insertion of the number of touch rods 42. Thus, when the operator moves the active rod 4 vertically upwards, the active rod 4 can drive the number of touch rods 42 to insert into the left - hand fitting bin 2 and the right - hand restraint bin 3 through the driven extension rod 41, thereby completing the driving work of other components and thus completing the thread - cutting operation on the sewing thread.
[0022] The working principle and usage process of the present utility model: The operator can install the sewing machine on the top of the operation platform 1 through the mounting base 14. Then, the operator can perform sewing operations on the fabric using the sewing machine. When the sewing operation is completed and the operator needs to perform a thread - cutting operation on the sewing thread, the blocking plate 13 can be slid to one side of the guiding frame 12 to expose the active rod 4 to the outside. Then, the operator can lift the active rod 4 upwards. When the active rod 4 moves, it will drive a number of touch rods 42 to move through the driven extension rod 41, causing the number of touch rods 42 to insert into the left - hand fitting bin 2 and the right - hand restraint bin 3. The number of touch rods 42 will respectively come into contact with the connecting inclined blocks 36 on one side of the positioning block 31, the tool body 33, and the clamping block 34, causing the positioning block 31 to slide out from the inside of the right - hand restraint bin 3. The positioning block 31 will move to the outside of the sewing thread, and the sewing thread will be located in the middle of the positioning block 31 through the slotted guide. Then, the two clamping blocks 34 inside the left - hand fitting bin 2 and the right - hand restraint bin 3 will perform a horizontal movement. When they slide horizontally towards each other, they will come into contact with both sides of the sewing thread and fix the sewing thread. Then, when the tool body 33 comes into contact with the sewing thread, since the sewing thread at the upper and lower positions of the thread - cutting position is fixed, the sewing thread will not move, thus avoiding situations such as pulling and traction of the sewing thread during the thread - cutting operation.
