[0015] The following embodiments will be described in detail with reference to the accompanying drawings. In the drawings and description, similar or identical parts are referred to by the same reference numerals. Furthermore, in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of the utility model. Any obvious modifications or alterations made to this utility model do not depart from its spirit and scope.

[0016] Please see Figure 1-5 As shown, the present invention proposes a flatbed sewing machine, including a worktable 2 and a sewing machine body 1 mounted on the top of the worktable 2, a pressing mechanism 3 mounted on the top of the worktable 2 and located at the front end of the sewing machine body 1, and a bracket mechanism 4 mounted on the top of the worktable 2 and located on one side of the sewing machine body 1. The pressing mechanism 3 includes two support wheels 307 rotatably mounted inside the worktable 2 and symmetrically distributed, and a movable frame 304 hingedly mounted on the top of the worktable 2 and located on one side of the support wheels 307. A shaft frame 301 is fixedly mounted on one side of the movable frame 304, and a pressure roller 303 that cooperates with the support wheels 307 is rotatably mounted on the bottom of the shaft frame 301. The bracket mechanism 4 includes a movable seat 401 slidably mounted on the top of the worktable 2, a telescopic frame 402 fixedly mounted on the top of the movable seat 401, a limiting seat 405 rotatably mounted on one side of the telescopic frame 402, and a support plate 406 fixedly mounted on the bottom of the limiting seat 405.

[0017] Based on the above structural configuration, this flatbed sewing machine consists of a sewing machine body 1, a worktable 2, a pressing mechanism 3, and a support mechanism 4. The pressing mechanism 3 facilitates continuous pressing of the fabric during feeding, preventing the fabric from becoming loose and skewed. The sewing machine body 1 facilitates sewing operations. During sewing, when a worker uses one hand to pull the fabric out, the support mechanism 4 supports the arm, preventing discomfort caused by prolonged arm suspension. Specifically, in operation, by flipping the shaft frame 301 upwards, the pressure roller 303 can be separated from the support roller 307, allowing the area of ​​fabric to be sewn to be placed on the support roller 307. Loosening the shaft frame 301 allows the pressure roller 303 to be separated from the support roller 307. The pressing mechanism facilitates the pressing of the fabric. The rolling action of the pressure roller 303 and the support roller 307 allows for easy fabric movement and feeding, preventing the fabric from becoming loose and causing skewing during sewing. During sewing, the telescopic frame 402 can extend and retract vertically, allowing for easy adjustment of the height of the support plate 406. Placing the arm on the support plate 406 provides convenient support. The groove on the inner side of the limiting seat 405 provides convenient elbow restraint. When the arm pulls the fabric out, the movement of the movable seat 401 allows the support plate 406 and the limiting seat 405 to move with the arm, preventing the arm from being suspended in the air for a long time and causing physical exhaustion and soreness.

[0018] Furthermore, the top of the workbench 2 is provided with a movable groove 202 for the support wheel 307 to rotate, and a sliding groove 203 for the movable seat 401 to slide. The movable groove 202 allows the support wheel 307 to rotate, and the sliding groove 203 facilitates the sliding of the movable seat 401, enabling the entire bracket mechanism 4 to move with the arm.

[0019] Furthermore, a handle 302 is fixedly installed on the top of the shaft frame 301, and a tension spring 305 is fixedly connected between the movable frame 304 and the worktable 2. The handle 302 allows the shaft frame 301 to be easily rotated upwards, stretching the tension spring 305. Releasing the handle 302 allows the tension spring 305 to contract, causing the shaft frame 301 to rotate downwards and reset, providing downward pressure to the pressure roller 303 and facilitating the pressing of the fabric.

[0020] Furthermore, anti-slip strips 306 arranged in a circular array are fixedly installed on the surfaces of both the pressure roller 303 and the support roller 307, and a support leg 201 is fixedly installed on the bottom of the worktable 2. The anti-slip strips 306 can increase the friction between the fabric and the pressure roller 303 and the support roller 307, preventing slippage. The support leg 201 can conveniently support the worktable 2, facilitating the sewing operation of the fabric.

[0021] Furthermore, a rotating shaft 403 is rotatably mounted on the top of the telescopic frame 402, and the rotating shaft 403 is fixedly connected to the limiting seat 405 via a fixed seat 404. The rotating shaft 403 enables the limiting seat 405 to rotate with the movement of the arm, facilitating the arm's discharging operation of the fabric.

[0022] Furthermore, a protective pad 407 is adhered to the top of the support plate 406, and anti-slip protrusions 408 are evenly distributed in a rectangular array on the top of the protective pad 407. When the support plate 406 supports the arm, the protective pad 407 improves the comfort of the arm, and the anti-slip protrusions 408 increase the friction between the arm and the protective pad 407. This allows the support plate 406 to move synchronously with the arm during movement, facilitating continuous support and preventing slippage.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
