[0002] Dress trousers are trousers with side seams on the legs, a front and back, and a design that coordinates with the body shape. They are mainly worn with suit jackets. Dress trousers require cutting during processing, and this cutting process requires clamps to hold the trousers in place and tighten them. This effectively prevents wrinkles from forming during the cutting process. Existing dress trouser cutting clamps, in order to increase the practicality of the device, have installed adjustable fixing components to tighten the trousers and achieve a fixing effect, which greatly increases the practicality of the device. Although this increases the practicality of the device to a certain extent, the cutting process of dress trousers will produce some fabric scraps and thread residue on the device, requiring manual cleaning, making the cleaning process time-consuming and labor-intensive.
[0003] A search revealed a Chinese patent document (authorization announcement number CN220057443U), which relates to the field of trousers technology and discloses a trousers cutting clamp, comprising a main body, an adjustment mechanism, a support mechanism, and a moving mechanism.

[0024] Examples, such as Figures 1 to 4 As shown, a fixing component 5 for cutting and fixing trousers is installed at the top of the base 1. Two adjusting plates 3 are hinged to the top of the base 1, and multiple mounting plates 6 are fixedly connected to the inner side of the base 1. A guide rod 7 is fixedly connected between two mounting plates 6. A moving block 9 is slidably connected to the outer periphery of the guide rod 7. A return spring 8 is fixedly connected between the bottom end of the moving block 9 and the mounting plate 6. The return spring 8 is designed to drive the adjusting plate 3 to return to its original position when the winding wheel 12 releases the rope. A moving rod 10 is hinged to the side of the moving block 9. The end of the moving rod 10 away from the moving block 9 is hinged to the adjusting plate 3. A collection box 2 for collecting scraps of cloth is slidably connected to the inner side of the base 1. An active shaft 11 is rotatably connected to the inner side of the base 1. A stepper motor 13 is installed on the side of the base 1 to provide adjustment power for the active shaft 11. The stepper motor 13 is designed to drive the adjustment plate 3 to tilt, thereby facilitating the cleaning of rag scraps on the surface of the adjustment plate 3. Two symmetrical take-up wheels 12 are fixedly connected to the outer periphery of the active shaft 11. A connecting rope 14 connected to the moving block 9 is fixedly connected to the outer periphery of the take-up wheels 12. A U-shaped limiting plate 4 is fixedly connected to the top of the adjustment plate 3. The limiting plate 4, in conjunction with the limiting hook 54, can prevent the adjustment plate 3 from tilting due to pressure during the shearing process. During the horizontal movement of the mounting frame 55, the limiting hook 54 and the limiting plate 4 are slidably connected, and the limiting plate 4 is designed in an L-shape.
[0025] The fixing component 5 includes a mounting box 51 embedded in the top of the base 1 and a lead screw 59 rotatably connected to the inside of the mounting box 51. The lead screw 59 has a two-section design and can drive two adjusting rods 53 to move in opposite directions. A drive motor 52 that provides adjustment power to the lead screw 59 is installed on the side of the mounting box 51. Two L-shaped adjusting rods 53 are threaded to the outer circumference of the lead screw 59. One end of the adjusting rod 53 passes through a limiting groove at the top of the mounting box 51 and is fixedly connected to a mounting bracket 55. The bottom end of the mounting bracket 55 is fixedly connected to a limiting hook 54 that works with the limiting plate 4. The top end of the mounting bracket 55 is threadedly connected to a screw 57, and the top end of the screw 57 is fixedly connected to an adjusting wheel 56. By rotating the adjusting wheel 56, the screw 57 is rotated, thereby driving the pressure plate 58 to press and fix the trousers. The bottom end of the screw 57 is rotatably connected to a pressure plate 58 that is slidably connected to the mounting bracket 55.
[0026] Both drive motor 52 and stepper motor 13 are conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. Both are controlled by remote control switches. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail. The scale of the attached drawings is for reference only and can be adjusted to a certain extent according to the actual use.
[0027] Working principle
[0028] In use, this trousers cutting clamp works by starting the drive motor 52, which moves the adjusting rod 53 around the lead screw 59. The movement of the adjusting rod 53 causes the mounting frame 55 to move in tandem. The trousers to be cut are placed between the pressure plate 58 and the mounting frame 55. The adjusting wheel 56 is rotated to adjust the screw 57, so that the pressure plate 58 presses the trousers firmly. The drive motor 52 also adjusts the two mounting frames 55 to fix the trousers in place. When it is necessary to clean the adjusting plate 3, the drive motor 52 is started to reset the mounting frame 55, ensuring that the limit hook 54 disengages from the limit plate 4. The stepper motor 13 is started to rotate the two winding wheels 12 around the drive shaft 11. The rotation of the winding wheels 12 can wind up the connecting rope 14, thereby moving the moving rod 10 on the side of the moving block 9. The adjustment of the moving rod 10 causes the adjusting plate 4 to tilt, so that the scraps of cloth on the surface of the adjusting plate 4 slide into the collection box 2 in the base 1, thus achieving an automatic cleaning effect.
