When the moving block 201b moves, the pulley 202c can be driven to slide in the support groove to support the moving block 201b, preventing the moving block 201b from deviating. The protective cover 202d is fixed to one side of the sewing machine body 101, and the support rod 201d is protected by the protective cover 202d.
[0041] Specifically, the limiting assembly 300 further includes a moving piece 302 arranged on the limiting wheel 301a. The moving piece 302 includes a gear 302a fixed to one side of the limiting wheel 301a. The gear 302a is rotatably connected to one side of the protective frame 201a through a rotating shaft. The gear 302a is provided with a rack 302b at the bottom. The gear 302a and the rack 302b are engaged.
[0042] The rack 302b is fixed to one side of the sewing machine body 101. When the limiting wheel 301a moves, the gear 302a can be driven to move on the rack 302b, so that the gear 302a can rotate. At this time, the rotation of the gear 302a can drive the limiting wheel 301a to rotate. By limiting the limiting wheel 301a, the rotation of the gear 302a can be prevented. At this time, the protective frame 201a can be limited.
[0043] Specifically, the limiting wheel 301a is sleeved with a support frame 302c on the outside. The limiting wheel 301a and the support frame 302c are rotatably connected through a rotating shaft. The movable column 301c is fixed with a sliding bar 302d at the top. The guide frame 301d is provided with a guide groove X corresponding to the sliding bar 302d. One end of the sliding bar 302d slides in the guide groove X.
[0044] The support frame 302c is used to support the limiting wheel 301a, preventing the limiting wheel 301a from deviating. By moving the guide frame 301d, the guide groove X can be driven to move. At this time, the movement of the guide groove X can extrude the sliding bar 302d, so that the sliding bar 302d drives the movable column 301c to move.

[0047] Specifically, the moving rod 302e is sleeved with a moving disc 302h on the outside, and the moving disc 302h is fixed with a second spring 302i on one side.
[0048] The moving rod 302e is moved to drive the moving disc 302h to move, and the moving disc 302h is extruded to drive the moving rod 302e to return to the original position.
[0049] Embodiment 3
[0050] Reference Figures 1-7 For the third embodiment of the utility model, the embodiment is based on the first two embodiments.
[0051] Specifically, the moving rod 302e is sleeved with a positioning shell 302j on the outside, and the positioning shell 302j and the moving rod 302e are movably connected.
[0052] The positioning shell 302j is fixed on the top of the support frame 302c, and the positioning shell 302j is arranged to support the moving rod 302e and prevent the moving rod 302e from deviating.
[0053] Specifically, the utility model also comprises a main assembly 100 arranged on the protection frame 201a, which comprises a sewing machine body 101 and a thread winding wheel 102.
[0054] The sewing machine body 101 is used for splicing and sewing various fabric parts of sofa covers in sofa manufacturing, and is also used for repairing damaged sofas, sewing after thread opening, or sewing after replacing sofa covers during sofa renovation.
[0055] Specifically, the sewing machine body 101 is fixed with a switch 103 on the top.
[0056] The switch 103 is a control component of the power supply path of the sewing machine body 101. When the user needs to use the sewing machine body 101 to perform sewing work, the switch 103 is pressed to turn on the power supply, so that the sofa can be sewn.
[0057] In use, the operator presses the switch 103 on the top of the sewing machine body 101 to turn on the power supply and make the sewing machine enter the preparation state. At this time, if the protective frame 201a is in the protective position of the needle, the protective frame 201a will not move randomly due to the action of the limiting assembly 300. Specifically, the movement of the protective frame 201a drives the rotation of the limiting wheel 301a, and the inclined surface of the limiting block 301b is arranged to one-way limit the protective frame 201a, preventing the reverse rotation of the limiting wheel 301a, thereby keeping the position of the protective frame 201a stable.
[0058] Then, the operator needs to remove the protection of the needle by the protective frame 201a if he wants to start sewing operation. By pressing the push plate 302g, the moving rod 302e is driven to move, the moving rod 302e drives the guide frame 301d to move, the guide groove X on the guide frame 301d extrudes the sliding bar 302d, the sliding bar 302d drives the movable column 301c to move, and then drives the limiting block 301b to separate from the limiting wheel 301a, thereby removing the limiting of the limiting wheel 301a. At this time, the limiting wheel 301a can be reversed, and the protective frame 201a is no longer limited. At the same time, the moving rod 302e moves to drive the moving disc 302h to move, and the second spring 302i is extruded.
[0059] After the protective frame 201a is removed from the limiting, the movement of the protective frame 201a drives the movement of the moving block 201b, the pulley 202c on one side of the moving block 201b slides in the support groove on one side of the sewing machine body 101 to support the moving block 201b and prevent it from deviating. At the same time, the movement of the protective frame 201a also drives the movement of the sliding block 201c on the support rod 201d, and the positioning block 202a at one end of the support rod 201d supports the support rod 201d to prevent it from deviating. When the protective frame 201a moves away from the needle, the first spring 202b is extruded.
[0060] Then, the operator can start using the sewing machine body 101 for sofa fabric stitching work. The mechanical structure inside the sewing machine body 101 starts to operate under the drive of the power supply, the needle makes up and down reciprocating motion, the thread winding wheel 102 winds the thread on its wheel body, the thread is drawn from the thread winding wheel 102, passes through a series of guide devices to the needle, thereby realizing the sewing of the sofa fabric. During the sewing process, if the protective frame 201a has a slight movement trend, due to the existence of the limiting assembly 300, such as the rotation of the limiting wheel 301a will drive the gear 302a to move on the rack 302b, make the gear 302a rotate, and then drive the limiting wheel 301a to rotate, and the limiting wheel 301a is limited in one direction by the limiting block 301b to prevent it from reversing, thereby ensuring that the protective frame 201a will not move back to the original position at will to interfere with the sewing operation.
[0061] When the sewing work is completed, loosen the push plate 302g, the force of the second spring 302i back bounce drives the moving rod 302e to return to the original position, and the operator can move the protective frame 201a back to protect the needle. At this time, the protective frame 201a returns to the original position under the action of the force of the first spring 202b back bounce, and drives the sliding block 201c to move on the support rod 201d, the pulley 202c on one side of the moving block 201b also slides in the support groove, finally the protective frame 201a returns to the end of the sewing machine body 101, and protects the needle, preventing the needle from causing accidental injury to personnel in a non-working state, and also protecting the needle from damage caused by external impact, thus completing a complete sewing operation process. The cooperation of each component in the whole process ensures the safe, stable and efficient use of the sewing machine.
[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
