[0025] Furthermore, the lifting device includes a lifting groove 11 provided on the bottom surface of the frame body 1, and the side wall of the lifting groove 11 is slidably connected with a lifting plate 8, the bottom surface of the lifting plate 8 is fixedly connected to the upper surface of the caster 5, and the upper surface of the lifting plate 8 is fixedly connected with a lifting threaded rod 9, one end of the lifting threaded rod 9 passes through the bottom surface of the frame body 1 and is slidably connected to the frame body 1, and the side wall of the lifting threaded rod 9 is threadedly connected with a lifting threaded sleeve 10, and the bottom surface of the lifting threaded sleeve 10 is rotatably connected to the side wall of the frame body 1; by setting the lifting groove 11, the lifting plate 8, the lifting threaded rod 9 and the lifting threaded sleeve 10 for use together, when the frame body 1 When it moves to the specified position, the lifting threaded sleeve 10 is rotated to make the lifting threaded rod 9 drive the lifting plate 8 to slide and rise along the lifting groove 11, thereby raising the caster 5, and the suction cup 4 fixedly connected to the bottom surface of the descending frame body 1 will contact with the ground, and then automatically adsorb, so that the fixed frame body 1 is fixed, to prevent the caster 5 from loosening and shifting when using the sewing machine, thereby improving the safety of use. When the frame body 1 needs to be moved, the lifting threaded sleeve 10 is rotated in the opposite direction, so that the lifting threaded rod 9 drives the lifting plate 8 to descend, and then the caster 5 will contact with the ground, at this time, the suction cup 4 is released, and then the frame body 1 can be moved, which is simple and convenient.

[0026] Furthermore, the horizontal adjustment device includes a horizontal groove 12 opened on the bottom surface of the table plate 3, and the inner wall of the horizontal groove 12 is slidably connected with a horizontal rod 13, the bottom surface of the horizontal rod 13 is fixedly connected with an adjustment rod 14, and the side wall sliding sleeve of the adjustment rod 14 is provided with a fixed sleeve 15, the bottom surface of the fixed sleeve 15 is fixedly connected to the upper surface of the frame body 1, and the side wall of the fixed sleeve 15 is slidably connected with an adjustment sleeve 16, the top surface of the adjustment sleeve 16 is fixedly connected to the side wall of the adjustment rod 14, and the bottom surface of the adjustment sleeve 16 is fixedly connected to a strip rod, the bottom surface of the strip rod is fixedly connected with an adjustment threaded rod 17, and one end of the adjustment threaded rod 17 passes through the side wall of the frame body 1 and is rotatably connected to the frame body 1, the side wall of the adjustment threaded rod 17 is threadedly connected with an adjustment threaded sleeve 18, and the upper surface of the adjustment threaded sleeve 18 is fixed to the frame body 1 side wall is rotatably connected; by setting the horizontal groove 12, the horizontal rod 13, the adjusting rod 14, the fixing sleeve 15, the adjusting sleeve 16, the strip rod, the adjusting threaded rod 17 and the adjusting threaded sleeve 18, when the frame body 1 is fixed, if the bottom ground is uneven, this will cause the table 3 to tilt, and the adjusting threaded sleeve 18 can be rotated so that the adjusting threaded rod 17 can raise the adjusting rod 14 through the cooperation of the strip rod and the adjusting sleeve 16. At this time, the adjusting rod 14 will slide and rise along the fixing sleeve 15, and the horizontal rod 13 fixedly connected to the side wall of the adjusting rod 14 will slide along the horizontal groove 12, thereby causing the table 3 to rise, and the reverse rotation of the adjusting threaded sleeve 18 will cause the table 3 to drop, thereby adjusting the horizontal position of the table 3, keeping the table 3 always in a horizontal state, and preventing the sewing machine from tilting and affecting the use.

[0027] Furthermore, the side walls of the adjusting thread sleeve 18 and the lifting thread sleeve 10 are both rotatably connected with an anti-loosening sleeve 19, and the upper surface of the anti-loosening sleeve 19 is fixedly connected to the side wall of the frame body 1, and the side wall of the anti-loosening sleeve 19 is threadedly connected with a top screw 20, and one end of the top screw 20 is against the side wall of the adjusting thread sleeve 18 or the lifting thread sleeve 10; by setting the top screw 20 and the anti-loosening sleeve 19 for coordinated use, when the positions of the lifting thread sleeve 10 and the adjusting thread sleeve 18 are adjusted, the top screw 20 is rotated so that one end of the top screw 20 is against the side wall of the adjusting thread sleeve 18 or the lifting thread sleeve 10, and then the lifting thread sleeve 10 and the adjusting thread sleeve 18 are fixedly adjusted to prevent the lifting thread sleeve 10 and the adjusting thread sleeve 18 from loosening when the sewing machine is used, thereby improving the safety of use.

[0028] Furthermore, the side wall of the horizontal rod 13 is rotatably connected with a rolling sleeve 21 ; by providing the rolling sleeve 21 , the movement of the horizontal rod 13 in the horizontal groove 12 is facilitated.

[0029] Furthermore, a weighted rod 22 is fixedly connected to the upper surface of the frame body 1 located above the suction cup 4, and a weighted plate 23 is slidably connected to the side wall of the weighted rod 22; by arranging the coordinated use of the weighted rod 22 and the weighted plate 23, the stability of the frame body 1 is improved, and when the weight on the table plate 3 is concentrated on one side, the number of weighted plates 23 on the weighted rod 22 on the opposite side can be increased to keep the force on the frame body 1 uniform and prevent the frame body 1 from tilting. At the same time, when the frame body 1 needs to be moved, the weighted plate 23 can be removed by sliding along the weighted rod 22, which will not affect the movement of the frame body 1, which is safe and convenient.
