[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0020] Example 1

[0021] See Figures 1 to 3As shown, the cardboard creasing device involved in this embodiment includes two side frames 1 arranged symmetrically on the left and right, and a top plate 2 connected between the side frames 1. A pressure plate 3 is provided at the bottom of the side frame 1. A wheel hole 4 is opened on the pressure plate 3. Wheel frames 5 are respectively provided on the left and right sides of the wheel hole 4. A guide wheel 6 extending out of the wheel hole is rotatably connected between the wheel frames 5. A wheel axle 7 with its axis extending left and right passes through the side frame 1. A rolling roller 8 is rotatably connected to the wheel axle 7. A horizontally placed "E"-shaped composite hole 9 is opened on the side frame 1. The wheel axle 7 is slidably connected in the composite hole 9. The composite hole 9 includes an upper adjustment hole 91 extending vertically and located at the highest position, a lower adjustment hole 92 extending vertically and located at the lowest position, and a middle adjustment hole 93 extending vertically and located in the middle position. A mounting ring 10 is sleeved on the wheel axle 7 and located between the side frames. The mounting ring 10 is rotatably connected to the wheel axle 7. A tension spring 11 is connected between the mounting ring 10 and the top plate 2.

[0022] Furthermore, the top plate 2 is provided with a handrail 12.

[0023] Furthermore, the inner and outer sides of the side frame 1 are respectively provided with retaining ring grooves (unmarked) on the wheel axle, and the retaining ring grooves are provided with outer retaining rings 13 that restrict the axial movement of the wheel axle.

[0024] Furthermore, the tension springs 11 are arranged symmetrically on both sides of the rolling roller 8.

[0025] Furthermore, each of the pressure plates 3 has at least two wheel holes; the wheel holes 4 are arranged at equal intervals along the length of the pressure plate 3.

[0026] In this embodiment, the rolling depth is changed by altering the position of the axle 7 within the composite hole 9, thereby adjusting the distance of the rolling roller 8 extending beyond the bottom surface of the pressure plate 3. When the axle 7 is in the upper adjustment hole 91, the distance of the rolling roller 8 extending beyond the bottom surface of the pressure plate 3 is minimized, resulting in the shallowest rolling depth. When the axle 7 is in the lower adjustment hole 92, the distance of the rolling roller 8 extending beyond the bottom surface of the pressure plate 3 is maximized, resulting in the deepest rolling depth. When the axle 7 is in the middle adjustment hole 93, the distance of the rolling roller 8 extending beyond the bottom surface of the pressure plate 3 is moderate, resulting in a moderate rolling depth.

[0027] The tension spring 11 is used to tighten the axle 7 in its natural state and prevent it from shifting.

[0028] The armrest 12 is designed for gripping, making it convenient to operate the indentation device by rolling.

[0029] Example 2

[0030] See Figures 1 to 3As shown, the cardboard creasing device involved in this embodiment is further configured, based on embodiment 1, with the axle 7 having an annular positioning groove 14 for the mounting ring 10 to be inserted into and for restricting axial movement.

[0031] In this embodiment, the annular positioning groove 14 is provided to allow the mounting ring 10 to be engaged and to restrict its axial movement.

[0032] Example 3

[0033] See Figures 1 to 3 As shown, the cardboard creasing device involved in this embodiment is further configured, based on embodiment 1, to have a handle 15 at one end of the axle 7.

[0034] In this embodiment, a handle 15 is provided at one end of the axle 7 for gripping, which facilitates the adjustment of the position of the axle 7 within the composite hole 9.

[0035] The cardboard creasing device involved in this utility model has a hand-operated rolling creasing mechanism, which makes creasing convenient and flexible. The guide wheels arranged on one side can make the creasing mechanism move in a straight line to ensure that the creasing is straight. In addition, the extension size of the pressure wheel is adjustable, thereby achieving the effect of adjusting the rolling creasing depth. The overall function is complete and the practicality is strong.
