[0002] Cotton and linen clothes are textiles blended from cotton and linen. This material has both the characteristics of linen and the advantages of cotton. Cotton and linen mixed fabrics effectively avoid the shortcomings of both linen and cotton. The advantages and disadvantages of the two complement each other, making it the best choice for summer clothes.

[0003] People usually use sewing machines to make cotton and linen clothes. For example, the existing patent with publication number CN218508020U discloses a sewing machine, which clamps two semi-transparent protective shells in annular grooves of appropriate height according to the thickness of the clothes to be made, so as to ensure that there is space at the bottom of the transparent protective shell for pushing the clothes; the soft silicone sheet at the bottom of the transparent protective shell is set so as not to scratch the clothes, and the transparent protective shell is clamped in the annular groove by the suction force of the magnet ring and the iron sheet, which facilitates the disassembly and assembly of the transparent protective shell and prevents the operator from pricking his fingers when pushing the clothes.

[0004] However, in the above technical solution, although the user can prevent the user's fingers from being pricked when pushing clothes by snapping the transparent protective shell into the annular groove, if the user is accidentally subjected to external force when pushing the cloth with his fingers, the user's fingers will be hit against the bottom of the transparent protective shell. If the sewing machine is still working at this time, the needle on the sewing machine may pierce the user. Therefore, the utility model aims to provide a sewing machine that can push cloth without the user using his fingers to approach the needle. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figures 1 to 4 According to an embodiment of the utility model, a technical solution is provided: a convenient-to-operate sewing machine for making cotton and linen clothes, comprising a machine body 1 and an operating table 2 suitable for carrying the machine body 1, a machine column 3 is fixed at the first end of the machine body 1, a machine needle 4 is fixed at the bottom of the machine column 3, and also comprises a movable plate 5, which is arranged on the operating table 2 and arranged below the machine needle 4; a driving device 6 is used to drive the movable plate 5 to move along the length direction of the operating table 2; a clamping mechanism 7, which is arranged on the movable plate 5 and selectively fixes the cloth relative to the movable plate 5 to limit or allow the cloth to move relative to the movable plate 5.

[0023] The easy-to-operate sewing machine for making cotton and linen clothes adopts the above-mentioned structure. When the user needs to sew the cloth, the pressing mechanism 7 is first used to selectively press the cloth on the movable plate 5. When sewing, the driving mechanism is used to drive the movable plate 5 to move, so as to drive the cloth to move, so that the needle 4 can sew on the cloth. When sewing, the user does not need to put his fingers close to the needle 4 to prevent the user's fingers from being pricked by the needle 4.

[0024] In this embodiment, the driving device 6 includes a screw rod 8, and a first slot 9 is opened on the operating table 2 along its length direction. The movable plate 5 is placed in the first slot 9. The screw rod 8 movably passes through the operating table 2 and extends into the first slot 9. The screw rod 8 is threadedly connected to the movable plate 5, and the first end of the screw rod 8 and the second end of the screw rod 8 are both rotatably connected to the operating table 2; when the user needs to move the movable plate 5, the user rotates the screw rod 8 to drive the movable plate 5 to move along the length direction of the first slot 9.

[0025] Alternatively, the driving device 6 can also be set to other suitable structures or forms, for example, directly connecting the output end of an electric telescopic rod to one end of the movable plate 5, and controlling the output end of the electric telescopic rod to extend and retract to control the movable plate 5 to move along the length direction of the operating table 2.

[0026] The pressing mechanism 7 comprises a vertical plate 10, a horizontal plate 11, a pressing column 13, a pressing plate 14 and a spring 12. The vertical plate 10 is fixed on the top of the movable plate 5, the horizontal plate 11 is fixed on the vertical plate 10, and there is a spacing between the horizontal plate 11 and the movable plate 5. The pressing column 13 movably passes through the horizontal plate 11, and the pressing plate 14 is arranged at the bottom of the pressing column 13. A spring 12 is sleeved on the pressing column 13, and the spring 12 is sleeved between the pressing plate 14 and the horizontal plate 11; when the user needs to press the cloth against the movable plate 5, the pressing column 13 is first pulled up to make the spring 12 between the pressing plate 14 and the horizontal plate 11 undergo elastic deformation. At this time, the spring 12 will give the pressing plate 14 an elastic pre-tightening force. Subsequently, the cloth is placed on the movable plate 5. At this time, the user releases the pressing column 13, and the spring 12 will elastically press the pressing plate 14 against the movable plate 5 to fix the cloth and the movable plate 5 relatively.

[0027] Alternatively, the pressing mechanism 7 can also be set to other suitable structures or forms, for example; using a pressing part to vertically penetrate the horizontal plate 11, the pressing part and the horizontal plate 11 are threadedly connected, and a pressing plate 14 is installed at the bottom of the pressing part, and the pressing plate 14 is driven downward by rotating the pressing part to press the cloth against the movable plate 5.

[0028] In this embodiment, a friction-increasing portion 15 is provided at the bottom of the pressure plate 14; after the pressure plate 14 is pressed against the cloth, the friction-increasing portion 15 at the bottom of the pressure plate 14 will increase the friction between the cloth and the pressure plate 14, further limiting the cloth from detaching from the pressure plate 14, so as to prevent the shaking of the cloth from affecting the accuracy of sewing.

[0029] In this embodiment, a limiting ball 16 is provided on the top of the pressure column 13; when the user lifts the pressure column 13 with the palm of his hand, the palm of the user will gradually slide toward the limiting ball 16. At this time, the limiting ball 16 can effectively prevent the palm of the user from leaving the pressure column 13, thereby increasing the stability of the user lifting the pressure column 13.

[0030] In this embodiment, a rotating plate 17 is vertically fixed to the second end of the screw rod 8, and a rotating shaft 18 is vertically provided at the free end of the rotating plate 17. The rotating shaft 18 is rotatably connected to the rotating plate 17; when the user needs to rotate the screw rod 8, the user holds the rotating shaft 18 and rotates the rotating plate 17 to drive the screw rod 8 to rotate, so that the user can save more effort when rotating the screw rod 8.

[0031] Working principle: when the user needs to sew the cloth, the pressing column 13 is pulled up first. When the user lifts the pressing column 13 with the palm of the user, the palm of the user will gradually slide toward the limiting ball 16. At this time, the limiting ball 16 can effectively prevent the user's palm from leaving the pressing column 13, thereby increasing the stability of the user lifting the pressing column 13. Subsequently, the spring 12 between the pressing plate 14 and the cross plate 11 undergoes elastic deformation. At this time, the spring 12 will give the pressing plate 14 an elastic pre-tightening force. Subsequently, the cloth is placed on the movable plate 5. At this time, the user releases the pressing column 13, and the spring 12 will elastically press the pressing plate 14 against the movable plate 5 to relative position the cloth to the movable plate 5. After the pressure plate 14 is pressed against the cloth, the friction increasing portion 15 at the bottom of the pressure plate 14 will increase the friction between the cloth and the pressure plate 14, further limiting the cloth from being separated from the pressure plate 14 to prevent the shaking of the cloth from affecting the accuracy of sewing. Then, the user rotates the screw rod 8 to drive the movable plate 5 to move along the length direction of the first slot 9 to drive the cloth to move. When the user needs to rotate the screw rod 8, hold the rotating shaft 18 and rotate the rotating plate 17 to drive the screw rod 8 to rotate, so that the user can save effort when rotating the screw rod 8. Then, the needle 4 is used to sew on the cloth. The user does not need to put his fingers close to the needle 4 when sewing to prevent the user's fingers from being pricked by the needle 4.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
