Specifically, a T-shaped slot is provided on the upper side of the slide rail 8, and a T-shaped block that matches the T-shaped slot is connected to the lower side of the slider 9. In this structure, the slider 9 can move reliably on the slide rail 8. A positioning device is provided between the slider 9 and the slide rail 8. Each slider 9 is installed with two clamps 6 that are controlled to open and close by a clamp cylinder 10. Specifically, the clamp cylinder 10 is installed on the slider 9 through a clamp cylinder mounting plate 11. The clamp cylinder mounting plate 11 is made of angle iron. A clamp valve 16 for controlling the clamp cylinder 10 is installed on the upper rear side of one of the brackets 7. Specifically, the clamp valve 16 adopts the existing technology and will not be described in detail here.

[0048] Before use, first, loosen the positioning device, adjust the positions of the two sliders 9 so that the clamping plate 6 is located at a predetermined position, and then fix the positioning device.

[0049] During use, a foot switch or other device is used to control the clamping valves 16, causing both clamps 6 on each slider 9 to open simultaneously. The foot switch and other devices utilize existing technology and will not be described in detail here. The operator then aligns the two trouser legs with the two pairs of clamps 6, which then close to clamp the two legs, facilitating ironing and other processes. This makes the machine easy to use and improves production efficiency.

[0050] The upper shell 2 is also included and can be installed on the upper part of the lower shell 1. The upper shell 2 is provided with a splint movable groove 3 for accommodating a splint 6 to pass through.
