[0021] Example 1, as Figures 1-4 As shown, this embodiment proposes a high-security bag, including a bag body 1 and a connecting mechanism; the bag body 1 is provided with a first telescopic pull rod 2 and a second telescopic pull rod 3, a sliding rod 4 is slidably connected to the second telescopic pull rod 3, a pin 5 is provided on the sliding rod 4, a fixing block 6 is provided on the pin 5, and a positioning groove is provided on the first telescopic pull rod 2 for the pin 5 and the fixing block 6 to be embedded.

[0022] The connecting mechanism includes a button 7 slidably connected to the first telescopic rod 2, a connecting rod 8 disposed on the button 7, a disc 9 disposed on the connecting rod 8 and slidably connected to the first telescopic rod 2, two first wedges 10 symmetrically distributed on the disc 9, a second wedge 11 slidably connected to the first wedge 10, a moving rod 12 disposed on the second wedge 11, a locking block 13 disposed on the moving rod 12, a vertical plate 15 disposed inside the first telescopic rod 2, and two springs 16 with their ends respectively disposed on the second wedge 11 and the vertical plate 15; the second wedge 11 is slidably disposed inside the first telescopic rod 2, and the inside of the fixing block 6 is provided with a groove for the locking block 13 to be embedded.

[0023] In this embodiment, when a person carrying a bag needs to handle other matters and finds it inconvenient to carry the bag, they can find a suitable stationary object nearby and press button 7. Button 7 moves the connecting rod 8 and the disc 9, causing the inclined surfaces of the two first wedges 10 and the second wedge 11 to press against each other and slide relative to each other. The second wedge 11, while moving the moving rod 12, also compresses the spring 16. When the moving rods 12 approach each other, the locking block 13 disengages from the groove. Then, the insert 5 and the fixing block 6 can be removed from the positioning groove by pulling the sliding rod 4. After the second telescopic rod 3 and the first telescopic rod 2 surround the selected object, the sliding rod 4 is reinserted into the positioning groove. Then, button 7 is released, and under the action of the spring 16, the second wedge 11 will move the moving rod 12 to resume its movement until the locking block 13 is embedded in the groove, thus achieving the connection and fixation of the second telescopic rod 3 and the first telescopic rod 2. This prevents theft or misappropriation by others after a short period of absence, and the operation is simple and convenient, with good practicality.

[0024] Example 2, as Figures 2-4 As shown, this embodiment proposes a highly secure bag. Compared with the first embodiment, in this embodiment, the sliding rod 4 is provided with four sliders 19 arranged in a circular array. The interior of the second telescopic rod 3 is provided with a guide groove for the sliders 19 to slide horizontally. The sliders 19 guide and restrict the movement of the sliding rod 4, preventing the sliding rod 4 from detaching from the second telescopic rod 3, while also ensuring that the insert 5 and the fixing block 6 can be accurately and quickly inserted into the positioning groove.

[0025] Both the button 7 and the disc 9 are provided with four guide blocks 18 arranged in a ring array. The first telescopic rod 2 is provided with a groove for the guide blocks 18 to slide vertically. The guide blocks 18 guide the movement of the button 7 and the disc 9, and prevent the disc 9 from deflecting, which would affect the accurate fitting of the first wedge 10 and the second wedge 11.

[0026] Two stabilizing rods 17 are provided on the upright plate 15. The stabilizing rods 17 extend into the interior of the second wedge block 11 and are slidably connected. The spring 16 is sleeved on the stabilizing rods 17. The stabilizing rods 17 guide the extension and retraction of the spring 16 and the movement of the second wedge block 11, preventing the spring 16 from bending or twisting and ensuring the service life of the spring 16.

[0027] The locking block 13 is provided with multiple protrusions 14 with triangular cross sections. The protrusions 14 are embedded in the fixing block 6. The protrusions 14 are used to further improve the tightness of the locking block 13 and the fixing block 6 when they are engaged, thereby improving the stability of the connection between the second telescopic rod 3 and the first telescopic rod 2.

[0028] Example 3, as Figure 2 and Figure 3 As shown, this embodiment proposes a highly secure bag. Compared with the first embodiment, in this embodiment, a sliding cylinder 20 is slidably connected to the first telescopic pull rod 2. Both the sliding cylinder 20 and the sliding rod 4 are provided with through holes, which are adapted to a first combination lock 21. The bag body 1 is provided with a zipper and a second combination lock 22. The bag body 1 is also provided with a side handle 23 and four rollers 24.

[0029] In this embodiment, when it is necessary to leave the bag for a long time, the slide cylinder 20 can be slid towards the second telescopic pull rod 3 until the axis of the through hole on the slide cylinder 20 and the slide rod 4 are aligned. Then, the locking rod of the first combination lock 21 is passed through the through hole and locked. Finally, the combination dial is scrambled, thereby ensuring that even if the bag is left for a long time, it will be safely fixed in the designated position, which fully guarantees the safety of the bag. The second combination lock 22 is used to lock the zipper of the bag body 1, the side handle 23 is used to lift the bag body 1, and the roller 24 is used to move the bag body 1.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
