The positioning post 4 and the positioning portion 4a have similar structures, and the positioning post 4 is taken as an example for description. The positioning post 4 includes a post main body 40 and a mounting arm 41 extending from the post main body 40, and the post main body 40 is provided with a slide groove 401 extending vertically along a center line O-O between the left row of rollers a and the right row of rollers b. The positioning column 4 is located outside the space between the left and right support frames 1, 1a and is mounted to the peripheral enclosing plate 8 suggested and discussed below through the mounting arm 41 so as to be indirectly attached to the bottom frame 13 and have a fixed position relative to the left and right support frames 1, 1 a. Of course, in other embodiments, the positioning column 4 may also be located in the space between the left support frame 1 and the right support frame 1a and directly fixed to the bottom frame 13.
As shown in fig. 4, a pair of synchronizing devices (3, 3a) is further disposed between the left support frame 1 and the right support frame 1a, and the pair of synchronizing devices (3, 3a) are respectively disposed at the front and rear sides of the underframe.

The synchronizer 3 is in a herringbone shape and comprises a first transmission arm and a second transmission arm (31 and 32), the head ends (312 and 322) of the first transmission arm and the second transmission arm (31 and 32) are hinged together through a hinge shaft 33, the hinge shaft 33 is arranged in the sliding groove 401 of the positioning column 4 in a sliding mode and keeps moving up and down on a center line O-O between the left row of rollers a and the right row of rollers b, the tail end 311 of the first transmission arm 31 is arranged on the left support frame 1 in a rotating mode, and the tail end 321 of the second transmission arm 32 is arranged on the right support frame 1a in a rotating mode. In this way, the first and second transmission arms (31, 32) are not only simultaneously associated with the positioning column 4 but also respectively associated with the left support frame 1 or the right support frame 1 a. The sliding device further comprises a moving driver 7 for driving the left support frame 1 and the right support frame 1a to relatively approach or gradually separate from each other synchronously, an output shaft of the moving driver 7 is connected to the right support frame 1a, when the moving driver 7 drives the right support frame 1a to move on the sliding support rails (2, 2 a) and gradually separate from the left support frame 1, the second transmission arm 32 rotates around a tail end 321 and simultaneously drives the hinge shaft 33 to slide in the sliding groove 401, and the hinge shaft 33 in sliding drives the left support frame 1 to synchronously move on the sliding support rails (2, 2 a) through the first transmission arm 31 so as to gradually separate from the right support frame 2. Conversely, when the moving driver 7 drives the right support frame 1a to move on the sliding support rails (2, 2 a) to approach the left support frame 1, the positioning column 4 and the synchronization device 3 are matched to draw the left support frame 1 to synchronously move to approach the right support frame 1 a. Of course, in other embodiments, it is also possible to use a different association structure between the synchronization device 3a and the positioning column 4a, the left support frame 1, and the right support frame 1a, for example, a second association structure to be discussed below; or only one positioning column and one synchronizing device are arranged.
According to the technical scheme, the following can be found: through the matching of the positioning columns (4, 4 a) and the synchronizing devices (3, 3a), the left support frame 1 and the right support frame 1a are enabled to synchronously approach or gradually separate under the condition that the position of a central line O-O between the left row of rollers a and the right row of rollers b is kept unchanged, so that the roller feeding frame can be adapted to materials with different sizes, the application range of the roller feeding frame is expanded, uniform and moderate clamping force can be applied from the left side and the right side of the material respectively, and the pushing speed is improved. In addition, the pair of positioning columns (4, 4 a) and the pair of synchronizing devices (3, 3a) are arranged, so that the pair of positioning columns (4, 4 a) and the pair of synchronizing devices (3, 3a) can synchronously control the movement of the left support frame 1 and the right support frame 1a from the front side and the rear side, the movement stability of the left support frame 1 and the right support frame 1a is improved, and the clamping force of the roller on the materials can be further uniformized.

Besides, the following associated structures can be selected to be adopted among the synchronizing device, the positioning column, the left support frame 1 and the right support frame 1 a:
in a second related structure, as shown in fig. 6, the synchronizing device 3 "is cross-shaped, the middle positions of the first and second transmission arms (31", 32 ") are hinged together through a hinge shaft 33", the hinge shaft 33 "is fixedly disposed on the positioning column 4" and is located on the center line O-O between the left row of rollers a and the right row of rollers b, the head ends (311 ", 321") of the first and second transmission arms (31 ", 32") are respectively slidably disposed on the chute 14 of the left support frame 1, and the tail ends (312 ", 322") of the first and second transmission arms (31 ", 32") are respectively slidably disposed on the chute 14a of the right support frame 1 a. When the left support frame 1 is driven to move on the sliding support rails (2, 2 a) and gradually leave the right support frame 1a, the head ends (311 ', 321') of the first and second transmission arms respectively rotate around the hinge shaft 33 'and slide towards each other to approach, so that the tail ends of the first and second transmission arms (31', 32 ') also simultaneously rotate around the hinge shaft 33' and slide towards each other to approach, thereby drawing the right support frame 1a to synchronously move on the sliding support rails (2, 2 a) and gradually leave the left support frame 1, and vice versa.
In the third related structure, as shown in fig. 7, the head end 312 'of the first transmission arm 31' is rotatably disposed on the positioning post 4 'through a left rotation shaft 313', the tail end 311 'of the first transmission arm 31 is slidably disposed on the chute 14 of the left support frame 1, the head end 322' of the second transmission arm 32 is rotatably disposed on the positioning post 4 'through a right rotation shaft 323', the tail end 321 'of the second transmission arm 32' is slidably disposed on the chute 14a of the right support frame 1a, a transmission tooth is disposed between the head end 312 'of the first transmission arm 31' and the head end 322 'of the second transmission arm 32', and the left rotation shaft 313 'and the right rotation shaft 323' are symmetrically disposed on the left and right sides of the center line O-O between the left row of rollers a and the right row of rollers b. Thus, when the left support frame 1 is driven to move on the sliding support rails (2, 2 a) to gradually separate from the right support frame 1a, the first transmission arm 31 'rotates around the left rotating shaft 313' and simultaneously drives the second transmission arm 32 'to rotate around the right rotating shaft 323' through the transmission teeth, so that the right support frame 1a is pulled to move on the sliding support rails (2, 2 a) to gradually separate from the left support frame 1, and vice versa.
A fourth related structure, which is relatively simple, can be understood with reference to fig. 4. The synchronizer 3 is in a herringbone shape, the head ends of the first and second transmission arms (31, 32) are hinged together through a hinge shaft 33, the hinge shaft 33 is fixedly arranged on the positioning column 4 and is positioned on a central line O-O between the left row of rollers a and the right row of rollers b, the tail end of the first transmission arm 31 is slidably arranged on the left support frame 1, and the tail end of the second transmission arm 32 is slidably arranged on the right support frame 1 a. Therefore, when the first and second transmission arms (31, 32) are synchronously driven by the mobile driver to open and close around the hinge shaft 33, the left and right support frames 1 and 1a can be drawn to relatively synchronously approach or gradually separate.
In a fifth related structure, as shown in fig. 8, the synchronizing device 3a is a parallelogram, the first transmission arm includes a pair of left transmission arms (31, 31 a), the second transmission arm includes a pair of right transmission arms (32, 32 a), the left ends of the pair of left transmission arms (31, 31 a) are rotatably disposed on the left support frame 1, the right ends of the pair of right transmission arms (32, 32 a) are rotatably disposed on the right support frame 1a, the left transmission arm 31 and the right transmission arm 32 are hinged together by a hinge shaft 33, the left transmission arm 31a and the right transmission arm 32a are hinged together by a hinge shaft 33a, and the hinge shafts (33, 33a) are respectively slidably disposed in the sliding groove 401 of the positioning column 4 and are held on the center line O-O between the left column roller a and the right column roller b to move up and down.
As shown in fig. 2 and 9, the portable electronic device further includes a peripheral enclosing plate 8 and a panel 81, the panel 81 is covered and pressed on the peripheral enclosing plate 8, an open portion 810 is reserved on the panel 81, the peripheral enclosing plate 8 and the panel 81 are combined to form an accommodating space 82, the support frame (1, 1 a) is accommodated in the accommodating space 82, and the roller group is exposed to the open portion 810. Therefore, the supporting frames (1, 1 a) are hidden by the peripheral enclosing plate 8 and the panel 81, and the phenomenon that a large amount of scrap iron and dust formed in the cutting process are adhered to the supporting frames (1, 1 a) to affect the use is avoided.
As shown in fig. 3, the device further comprises a pair of guide rails (9, 9 a), and the pair of guide rails (9, 9 a) are respectively arranged at the front and the rear sides of the support frame (1, 1 a).
