However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: Figure 1 - Figure 5 As shown, the utility model provides a double-trolley structure for a trolley case, including a side mounting plate 1, inner panels 9 are provided on both sides of the middle part of one side of the side mounting plate 1, and two ends of one side of the two inner panels 9 are provided with a No. 2 inner groove 20, and a side clamping block 12 is provided on one side of the No. 2 inner groove 20, and the side clamping block 12 is fixedly connected to the side mounting plate 1, and a threaded hole 11 is provided through one side of the inner panel 9, and a No. 1 through hole 14 is provided through one side of the side mounting plate 1, and a threaded rod 15 is provided between the No. 1 through hole 14 and the threaded hole 11, and telescopic pull rods 3 are installed on both sides of the middle part of the inside of the side mounting plate 1, and the upper ends of the two telescopic pull rods 3 are fixedly connected to square tube handles 4, and a round tube handle 5 is fixedly connected between the two square tube handles 4. The telescopic pull rod 3 and the regulating mechanism 7 are existing technologies and will not be elaborated on here.

[0028] The following is a detailed description of the specific settings and functions of this embodiment. The inner panel 9 is used to be installed on the inner side of the trolley case, and the trolley case fits together with the inner panel 9. In this way, the side of the trolley case will have a groove that matches the No. 2 inner groove 20. In this way, according to needs, any side of the interior of the trolley case can be processed into an area that matches the inner panel 9 and the side panel 1, so that the side panel 1 can be installed on any required side, which has higher applicability and does not occupy the space inside the trolley case, making it convenient to use. Through the setting of the inner recessed groove 6 and the round tube handle 5, the round tube handle 5 can fit the palm more closely, making it more comfortable to hold and use. The setting of the inner recessed groove 6 makes it easy to put the hand into the inner recessed groove 6 to facilitate the extraction of the telescopic pull rod 3. The button in the control mechanism 7 is set on the inner side of the inner recessed groove 6, which is more beautiful and more convenient to press and use.

[0029] Example 2: Figure 1 - Figure 5 As shown, one side of the side mounting plate 1 is provided with an inner groove 2 No. 1, and the through hole 14 is connected to the inner groove 2 No. 1. One end of the threaded rod 15 is fixedly connected to the connecting piece 8, and one side of the connecting piece 8 is fixedly connected to the rotating plate 10. The lower end of the round tube handle 5 is provided with an inner groove 6, and the inside of the round tube handle 5 and the square tube handle 4 are equipped with a regulating mechanism 7. A No. 2 through hole 21 is provided through the middle of the No. 2 inner groove 20, and a hexagonal groove 16 is provided at one end of the No. 2 through hole 21. The hexagonal groove 16 and the inside of the No. 2 through hole 21 are clamped with a bolt 13, and a nut 22 is installed at one end of the bolt 13. A plastic cap 17 is provided on one side of the nut 22, and a hexagonal groove 18 is provided on one side of the plastic cap 17. The hexagonal groove 18 is clamped with the nut 22, and a lining groove 19 is provided on one side of the side clamping block 12, which is clamped with the plastic cap 17.

[0030] The effect achieved by the entire embodiment is that, through the setting of the No. 1 inner groove 2, the rotating plate 10 is set on the inner side of the side mounting plate 1 to avoid protrusions, thereby preventing bumps and ensuring safety in use. Through the setting of the plastic card cap 17, it is used to cover the nut 22 on the side where the side mounting plate 1 is not installed, which is more aesthetically pleasing and not easy to scratch, and is convenient to use. The bolts 13 and nuts 22 are used to fix the inner mounting plate 9 to the inside of the trolley case. Through the setting of the rotating plate 10, the side mounting plate 1 and the trolley case are detachably installed, and the side mounting plate 1 can be installed on the appropriate side according to actual needs. This method has low cost and is convenient for replacement and use.

[0031] The use method and working principle of this device are as follows: during production, the side edge of the trolley case is stamped to produce a protrusion that fits into the No. 2 inner groove 20. The protrusion cooperates with the No. 2 inner groove 20, and the inner mounting plate 9 is fixed to the inner side of the trolley case using a nut 22 and a bolt 13. At the same time, a hole connected to the No. 2 through hole 21 and the threaded hole 11 needs to be opened in the trolley case. During use, the side mounting plate 1 is installed on one side of the trolley case according to personal use needs. During installation, the side clamping block 12 is aligned with the notch on the side of the trolley case. At the same time, the No. 1 through hole 14 is connected to the threaded hole 11. Hold the rotating plate 10 and pass the threaded rod 15 through the No. 1 through hole 14 and connect it with the threaded hole 11. Rotate the rotating plate 10 to squeeze and fix the side mounting plate 1 to the side of the trolley case. In this way, not only is the internal space occupied less, but the installation position can be changed at any time according to needs. Put your hand into the inner recessed groove 6, press the regulating mechanism 7, and pull the round tube handle 5 to pull out the telescopic pull rod 3.
