[0023] Example

[0024] See also Figure 1 , a sheet width adjustment mechanism provided in an embodiment of the utility model, the sheet width adjustment mechanism comprises:

[0025] A support frame 8 and a slideway 1; the support frame 8 is used to support the sheet material to be processed and adjust the processing width of the sheet material to be processed by its own displacement; wherein the left and right sides of the lower end of the support frame 8 are slidably mounted on the slideway 1, and the slideway 1 is provided to provide a sliding position for the support frame 8; the slideway 1 is installed at the upper end of the slideway base 5, and the slideway base 5 is provided to support the slideway 1 located at the lower end of the support frame 8;

[0026] Among them, a propulsion component is provided at the middle lower end of the support frame 8, and the operation of the propulsion component provides power output for pushing the support frame 8 to slide and displace on the upper end of the slideway 1, thereby adjusting the processing width of the sheet material to be processed placed on the upper end of the support frame 8; the installed propulsion component includes a fixed seat 7, a screw rod 3 and a nut bracket 4, the fixed seat 7 is installed at the middle lower end of the support frame 8, one end of the screw rod 3 is rotatably installed inside the fixed seat 7 at the middle lower end of the support frame 8, and the other end of the screw rod 3 and the nut bracket 4 are movably installed by means of a thread and a thread groove; the nut bracket 4 is installed and fixed on the mounting plate, and the mounting plate is used to stably support the nut bracket 4 and the slideway base 5 and provide an installation space; at the same time, a ruler 2 is also provided on the mounting plate, and the ruler 2 is visually used to judge the processing width of the sheet material to be processed placed on the upper end of the support frame 8;

[0028] In the embodiment of the present invention, when the sheet width adjustment mechanism is used, after the sheet to be processed is placed on the upper end of the support frame 8, the installed propulsion assembly is then started, that is, the operator applies force to the position of the handle 6 to push the screw rod 3 to rotate. Since the outer side of the screw rod 3 and the inner side of the nut bracket 4 are movably installed by means of the engagement of threads and thread grooves, when the screw rod 3 rotates, the fixed seat 7 at the middle lower end of the support frame 8 will be pushed to slide and displace; and when the fixed seat 7 slides and displaces, the support frame 8 will be driven to slide and displace on the slideway 1, thereby adjusting and changing the processing width of the sheet to be processed placed on the support frame 8; at the same time, the limit assembly installed on the screw rod 3 can control the rotation amplitude of the screw rod 3, and realize automatic locking after the rotating screw rod 3 is rotated and displaced to a certain distance position;
