[0030] A support material mounting plate 40 is installed above the workbench 1, and a support material stepping motor 46 is fixedly connected below the support material mounting plate 40. The power output shaft of the support material stepping motor 46 passes through the support material mounting plate 40 and is fixedly connected to the support material gear 44, driving the support material gear 44 to rotate.

[0031] The support material installation plate 40 is provided with a first support material transverse track 15 and a second support material transverse track 18. The first support material driving plate 45 is slidably installed on the first support material transverse track 15 through the first support material slider 43. The second support material driving plate is slidably installed on the second support material transverse track 18 through the second support material slider 56. The first support material driving plate 45 and the second support material driving plate are respectively provided with first racks on the opposite surfaces thereof, and the two first racks are meshed with the support material gear 44. The first support material driving plate 45 and the second support material driving plate are installed in parallel on both sides of the support material installation plate 40. When the support material gear 44 rotates, the first support material driving plate 45 and the second support material driving plate can be moved closer to or farther from each other.

[0032] The first supporting material driving plate 45 is provided with a first supporting material connecting plate 41, and the first supporting material connecting plate 41 is provided with a first supporting material longitudinal track 42 and a first supporting material cylinder 39.

Two first support material fixing rods 33 are fixedly mounted on the front end of the first clamping material mounting frame 37, and two first support material swing rods 34 are rotatably mounted on one side of the corresponding first support material fixing rod 33.

[0034] The side of the first clamping mounting frame 37 is rotatably connected to the upper and lower first material supporting driving cylinders 36 through the first material supporting cylinder mounting plate 53, and the first material supporting driving cylinder 36 is rotatably connected to the first material supporting swing rod 34. The first material supporting swing rod 34 is controlled to rotate, and the first material supporting swing rod 34 can cooperate with the first material supporting fixing rod 33 to open and close to control the clamping of the trouser waist opening. The upper end of the upper first material supporting fixing rod 33 is equipped with a first material supporting limit plate 35, which can locate the material release depth when placing the trouser waist position.

[0035] When placing the pants, the first material-supporting driving cylinder 36 contracts to drive the first material-supporting swing rod 34 to open relative to the first material-supporting fixing rod 33, and the placement depth of the pants is determined by the first material-supporting limiting plate 35. After the placement is completed, the piston rod of the first material-supporting driving cylinder 36 is pushed out to drive the first material-supporting swing rod 34 to swing, and the first material-supporting swing rod 34 and the first material-supporting fixing rod 33 are closed to clamp the pants. The material-supporting stepping motor 46 operates to drive the first material-clamping mounting frame 37 and the second material-clamping mounting frame 32 to slide to both sides through the first rack, so as to achieve the function of opening the pants.

During the process of stretching the trouser waist, when the pulling force generated by the trouser waist is greater than the resistance set by the first spring cylinder 51, the first material stay rotating plate 59 rotates around the first material stay bearing 58, and the first material stay rotating plate 59 drives the first material stay detection plate 17 to rotate. When the material stay first material stay sensor 38 detects the first material stay detection plate 17, the material stay first material stay sensor 38 sends a signal to stop the material stay stepping motor 46, and the first material stay driving plate 45 and the second material stay driving plate stop moving, and the trouser waist is stretched to the maximum state.

[0037] The second support driving plate is provided with a second support connecting plate 48, and the second support connecting plate 48 is provided with a second support longitudinal track and a second support cylinder 20. The second support longitudinal track is slidably provided with a second support longitudinal slide 21. The piston rod of the second support cylinder 20 is fixedly connected to the second support longitudinal slide 21 through the second cylinder connecting plate 22, and can drive the second support longitudinal slide 21 to slide.

[0038] The second material support longitudinal slide 21 is rotatably mounted with the second material support rotating plate 55 through the second material support bearing 54, and the second material clamping mounting frame 32 is fixedly mounted on the second material support rotating plate 55. The second material support fixing upper rod 30 is mounted on the front of the upper end of the second material clamping mounting frame 32, and the second material support limiting plate 31 is mounted on the upper end of the second material support fixing upper rod 30.
