The lower positions on the left and right sides of the limit frame are respectively slidably connected to the upper position of the rear end of an L-shaped adjusting member. Threaded holes are respectively provided on the side positions of the two adjusting members, and the left and right sides of the two-way rod are respectively located in the threaded holes of the two adjusting members. A motor B is fixedly installed on the left side of the limit frame, and the rotating shaft position of the motor B is fixedly connected to the left side of the two-way rod. The two adjusting members are symmetrically designed, and the bottom positions of the two adjusting members are rotatably connected to six horizontal rollers.

[0008] According to one embodiment of the utility model, the top position of the sliding frame is fixedly connected with a telescopic member, the front end position of the sliding frame is slidably connected with the rear end position of the lifting frame, the top position of the lifting frame is fixedly connected with the bottom position of the telescopic member, a sewing needle is provided at the lower position of the front end of the lifting frame, a threaded hole is provided at the side position of the sliding frame, and the rotating shaft of the motor A is located in the threaded hole of the sliding frame.

[0009] Compared with the prior art, the utility model has the following beneficial effects:
