[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] In order to facilitate the modification of trouser legs, refer to Figure 1 , Figure 2 and Figure 3As shown, a sewing machine 6 for modifying the trouser legs is included. The sewing machine 6 is a prior art and is used to sew the hidden section of the strap in the trouser legs, and sew the hidden section of the strap 4 into the interlayer in the trouser legs. The sewing machine 6 is set on a workbench 7. A lubrication unit is set in the path of the trouser body being dragged from the outside to the working area of ​​the sewing machine 6. The lubrication unit is used to reduce the friction generated when the trouser body is dragged on the workbench 7. When the trouser legs are sewn, the trouser body and one end of the trouser legs need to be pulled from the side of the workbench 7 away from the working area. When the trouser legs are dragged to the working area of ​​the sewing machine 6, the trouser body and the trouser legs will contact the other side of the workbench 7, thereby generating friction. On the one hand, it is inconvenient for the staff to drag the trouser legs. On the other hand, since the trouser body of the trouser legs that need to be modified is all brand new, the trouser body will become old faster after friction, thereby affecting the subsequent sales. The lubrication unit includes a groove 8 vertically downwardly opened from the surface of the workbench 7, and two connecting rods 9 and a roller 10 are arranged in the groove 8. The two connecting rods 9 are respectively arranged on both sides of the groove 8, and the roller 10 is arranged between the two connecting rods 9 and abuts against the trouser body of the trouser legs to be modified. When the staff pulls the trouser legs, the trouser body and the trouser legs will abut against the roller 10, which improves the convenience of the staff to pull the trouser legs and avoids friction with the surface of the workbench 7 to cause unnecessary damage.

[0018] Furthermore, the workbench 7 is provided with a positioning component for fixing one side of the trouser body and the trouser waist, and the positioning component includes a fixing block 11 arranged on the workbench 7, and a cavity with an open side is opened in the fixing block 11, and a pull rod 12 is arranged in the cavity, and the pull rod 12 passes through the cavity and extends to the end outside the fixing block 11 and is connected to a handle 13, and the end of the pull rod 12 located in the cavity is connected to a first pressing plate 14, and a second pressing plate 15 is arranged at the bottom of the cavity, and the first pressing plate 14 and the second pressing plate 15 are connected to a rotating rod 16 toward the open side of the cavity, and a spring 17 is sleeved on the outside of one end of the pull rod 12 located in the cavity, and one end of the spring 17 is in contact with the first pressing plate 14 The other end of the spring 17 is in contact with the top of the cavity. After pulling the handle 13, the pull rod 12 moves vertically upward, driving the first pressing plate 14 to move upward. At this time, there is a certain gap between the first pressing plate 14 and the second pressing plate 15, and at the same time there is a gap between the two rotating rods 16. The two sides of one end of the waistband of the trouser body are respectively inserted into the gap between the two rotating rods 16, and the handle 13 is released. The spring 17 is deformed, causing the first pressing plate 14 to drop and approach the second pressing plate 15 to clamp the waistband. When the staff pulls the trouser legs, the trouser legs can be pulled by the rotation of the rotating rod 16, which will make the trouser body and trouser legs straightened and in a tight state, which is more conducive to the staff to modify the trouser legs.

[0019] When in use, first, when sewing the trouser legs, one end of the trouser body and the trouser leg needs to be pulled from the side of the workbench 7 away from the working area. When the trouser legs are dragged to the working area of ​​the sewing machine 6, after the staff pulls the trouser legs, the trouser body and the trouser leg will abut against the roller 10, and the trouser legs are smoothly pulled into the working area of ​​the sewing machine 6, and the handle 13 is pulled to make the pull rod 12 move vertically upward, driving the first pressing plate 14 to move upward. At this time, there is a certain gap between the first pressing plate 14 and the second pressing plate 15, and there is a gap between the two rotating rods 16 at the same time. The two sides of one end of the waistband of the trouser body 1 are respectively inserted into the gap between the two rotating rods 16, and the handle 13 is released. The spring 17 is deformed, causing the first pressing plate 14 to drop and approach the second pressing plate 15 to clamp the trouser waistband. When the staff pulls the trouser legs, the trouser leg can be pulled by the rotation of the rotating rod 16, so that the trouser body and the trouser leg are straightened and in a tight state.
