DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 5 As shown, the utility model provides an upper clamping machine, including a connecting rod 1, the bottom end of the connecting rod 1 is fixedly connected with a special-shaped block 3, the special-shaped block 3 at the bottom end of the movable connecting rod 1 moves inside the shoe upper 17, at this time, the pulley 4 at the bottom end of the special-shaped block 3 slides inside the shoe upper 17, and drives the fixed block 18 tied to the outside of the extension block 5 at the front end of the special-shaped block 3 to slide, when the rotating plate 9 outside the fixed block 18 touches the narrow position of the shoe upper 17, the outer side of the shoe upper 17 squeezes the rotating plate 9 to tilt, and the first rotating rod 11 rotatably connected to the outside of the first fixed seat 10 on the left side of the rotating plate 9 squeezes the extension block 5 at the front end of the special-shaped block 3. The retractable rod 12 and the spring 13 sleeved on the outside, the spring 13 squeezes the second rotating rod 14 to tilt, and the bottom end of the second rotating rod 14 squeezes the second fixed seat 15 at the bottom end. At this time, the first rotating rod 11 is tilted in the direction of the second rotating rod 14. When the shoe upper 17 with a larger shoe size is crushed, the bolt 16 is turned clockwise to the outside. The bolt 16 passes through the inner center position of the moving block 8 and is spirally connected with the ring 7. At this time, the bolt 16 pulls the threaded shaft 6 out of the inside of the fixed block 18, and the moving block 8 drives the rotating plate 9 to extend outward, thereby adapting to shoe uppers 17 of different models.

[0024] Specifically, the outer side of the moving block 8 is rotatably connected to a rotating plate 9, the left side of the rotating plate 9 is fixedly connected to a first fixed seat 10, the outer side of the first fixed seat 10 is rotatably connected to a first rotating rod 11, the first rotating rod 11 rotatably connected to the outer side of the first fixed seat 10 on the left side of the rotating plate 9 squeezes the telescopic rod 12 and the spring 13 sleeved on the outer side, the spring 13 squeezes the second rotating rod 14 to tilt, the bottom end of the second rotating rod 14 squeezes the second fixed seat 15 at the bottom end, and at this time the first rotating rod 11 tilts in the direction of the second rotating rod 14.

[0025] Furthermore, the outer side of the second rotating rod 14 is rotatably connected to the second fixed seat 15 , and the rear side of the second fixed seat 15 is welded with a moving block 8 .

[0026] Furthermore, the shape of the special-shaped block 3 is set to be wide at the top and narrow at the bottom, and the special-shaped block 3 is set to be made of rubber material, so that the special-shaped block 3 can be easily inserted into the interior of the shoe upper 17.

[0027] It is worth noting that the outer side of the rotating plate 9 is tightly set on the inner side of the shoe upper 17, two groups of rotating plates 9 are provided, and the rotating plates 9 are set to rubber material, so it is not easy to damage the shoe upper 17 during the sliding and pressing process.

[0028] It is worth noting that the fixed block 18 and the movable block 8 are spirally connected. When the rotating plate 9 on the outside of the fixed block 18 touches the narrower position of the shoe upper 17, the outer side of the shoe upper 17 squeezes the rotating plate 9 to tilt.

[0029] It is worth mentioning that a handle 2 is set at the top of the connecting rod 1, and the handle 2 is set to a non-slip material, which is more convenient and not easy to slip when in use.

[0030] Among them, the spring 13 is the prior art and will not be described in detail. At the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left and right" perspectives of the device are as follows: Figure 1 The direction shown in the figure is used as the reference.

[0031] Working principle:

[0032] First, the staff member holds the handle 2 at the top of the connecting rod 1, and inserts the special-shaped block 3 at the bottom end of the connecting rod 1 into the interior of the shoe upper 17, and moves the special-shaped block 3 at the bottom end of the connecting rod 1 to move inside the shoe upper 17. At this time, the pulley 4 at the bottom end of the special-shaped block 3 slides inside the shoe upper 17, and drives the fixed block 18 tied to the outside of the extension block 5 at the front end of the special-shaped block 3 to slide. When the rotating plate 9 on the outside of the fixed block 18 touches the narrower position of the shoe upper 17, the outer side of the shoe upper 17 squeezes the rotating plate 9 to tilt, and the first rotating rod 11 connected to the outer side of the first fixed seat 10 on the left side of the rotating plate 9 rotates to squeeze the telescopic rod 12 and the spring 13 sleeved on the outside, and the spring 13 squeezes the second rotating rod 14 to tilt, and the bottom end of the second rotating rod 14 squeezes the second fixed seat 15 at the bottom. At this time, the first rotating rod 11 tilts toward the direction of the second rotating rod 14;

[0033] When rolling a shoe upper 17 with a larger shoe size, the bolt 16 is turned clockwise outward, and the bolt 16 then pulls the threaded shaft 6 out of the interior of the fixed block 18, and the moving block 8 drives the rotating plate 9 to extend outward, thereby adapting to shoe uppers 17 of different sizes.
