[0041] The foldable telescopic support comprises a telescopic tube assembly 1, a spring cable 2, a mounting structure 3 and at least three supporting legs 4. The telescopic tube assembly 1 comprises at least two nested tubes, and two adjacent tubes are axially slidable. The top end of the supporting leg 4 is rotatably connected to the telescopic tube assembly 1. The supporting leg 4 has a folded state and an unfolded state. When the supporting leg 4 is in the folded state, the bottom end of the supporting leg 4 is close to the top end of the telescopic tube assembly 1. When the supporting leg 4 is in the unfolded state, the bottom end of the supporting leg 4 is lower than the bottom end of the telescopic tube assembly 1. The supporting legs 4 define a storage area below the telescopic tube assembly 1. The spring cable 2 is arranged in the telescopic tube assembly 1. The top end of the spring cable 2 extends out of the top of the telescopic tube assembly 1 and is connected to an upper electrical connector 21. The upper electrical connector 21 is used to electrically connect an electronic device to provide power for the electronic device. The bottom end of the spring cable 2 extends out of the bottom of the telescopic tube assembly 1 and is connected to a lower electrical connector 22. The mounting structure 3 is arranged in the storage area and is connected to the bottom end of the telescopic tube assembly 1. Preferably, the center of gravity of the mounting structure 3 is located on the central axis of the telescopic tube assembly 1. The mounting structure 3 is used to mount a power supply device, including but not limited to a mobile power bank and the like. The lower electrical connector 22 is used to electrically connect the power supply device.

The lower connecting piece 5 has a lower mating threaded section that matches the lower threaded section. The mounting structure 3 is located directly below the lower connecting piece 5.

[0043] In one or more embodiments, a lower wire passing hole is arranged on the peripheral wall of the lower part of the outermost tube of the telescopic tube assembly 1. The bottom end of the spring cable 2 directly passes out of the lower wire passing hole and is connected to the lower electrical connector 22. The cross-sectional size of the lower electrical connector 22 is larger than the diameter of the lower wire passing hole, thereby preventing the lower electrical connector 22 from retracting into the telescopic tube assembly 1. In this embodiment, the bottom end of the outermost tube of the telescopic tube assembly 1 is also provided with a lower wire passing gap. The lower connecting piece 5 and the lower wire passing gap form a lower limiting opening 11. The bottom end of the spring cable 2 passes out of the lower limiting opening 11. The cross-sectional size of the lower electrical connector 22 is larger than the diameter of the lower limiting opening 11. Compared with the aforementioned direct arrangement of the lower wire passing hole, the scheme of forming the lower limiting opening 11 by the lower connecting piece 5 and the wire passing gap can facilitate the maintenance and replacement of the spring cable 2.

[0044] The top end of the pipe located in the innermost layer of the telescopic pipe assembly 1 is provided with an upper connecting piece 6, and the upper connecting piece 6 is provided with a connecting part 61 for connecting an electronic device.

[0045] Preferably, the pipe located in the innermost layer of the telescopic pipe assembly 1 is detachably connected with the upper connecting piece 6. The user can selectively replace the upper connecting piece 6 matched with the electronic device to be connected, thereby solving the pain point that various electronic devices have different connection matching structures.

[0046] Similarly, in one or more embodiments, an upper threading hole is arranged on the peripheral wall of the pipe located in the innermost layer of the telescopic pipe assembly 1, and the top end of the spring cable 2 directly passes out of the upper threading hole and is connected with the upper electric connector 21. The cross-sectional size of the upper electric connector 21 is greater than the caliber of the upper threading hole, thereby preventing the upper electric connector 21 from retracting into the telescopic pipe assembly 1. In the present embodiment, the top end of the pipe located in the innermost layer of the telescopic pipe assembly 1 is provided with an upper threading gap, the upper connecting piece 6 and the upper threading gap form an upper limiting opening 12, the top end of the spring cable 2 passes out of the upper limiting opening 12, and the cross-sectional size of the upper electric connector 21 is greater than the caliber of the upper limiting opening 12. It is easy to understand that in the foldable telescopic support of the present embodiment, the spring cable 2 can be completely detached and selectively installed according to actual needs, so as to carry different models of upper electric connectors 21 and lower electric connectors 22 to adapt to different electronic devices and power supply devices.

[0047] Embodiment two

[0048] Please refer to Figure 4 and Figure 5 Embodiment two of the utility model is a parallel technical scheme of embodiment one, and the difference between embodiment two and embodiment one is that the number of the mounting structures 3 is multiple, and the mounting structures 3 with multiple numbers are uniformly distributed around the telescopic pipe assembly 1, so that the gravity center of the foldable telescopic support can be balanced.

[0049] In the present embodiment, the lower connecting piece 5 comprises a nut part 51 and an extension part 52 connected with each other, the extension part 52 is in an inverted L shape, the nut part 51 is threadedly connected with the bottom end of the pipe located in the outermost layer of the telescopic pipe assembly 1, and the extension part 52 is connected with the mounting structure 3.

[0050] In addition, in the embodiment, a lower threading hole is arranged on the peripheral wall of the lower part of the pipe in the outermost layer of the telescopic pipe assembly 1, the bottom end of the spring cable 2 directly passes out of the lower threading hole and is connected to the lower electric connector 22, the cross-sectional size of the lower electric connector 22 is greater than the caliber of the lower threading hole, thereby preventing the lower electric connector 22 from retracting into the telescopic pipe assembly 1. At this time, when the power supply device is not suitable for the lower electric connector 22, the user can install a conversion connector on the lower electric connector 22 to adapt the power supply device, thereby avoiding the replacement of the spring cable 2 and causing the operation to be troublesome.

[0051] The above is only optional embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and the attached drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
