The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is a back-clip type double-clip movable power bank, comprising a power bank 1, positioning grooves 2 are provided on the four corners of the power bank 1, and positioning ports 3 connected to the outside are provided on the top surfaces of the positioning grooves 2, and adjustment blocks 12 are slidably arranged in the positioning grooves 2, and assembly grooves are provided on the top surfaces of the adjustment blocks 12, and assembly blocks 13 are provided in the assembly grooves, and connecting parts 15 are protruded on the top surfaces of the assembly blocks 13, and the connecting parts 15 extend to the outside through the positioning ports 3 and are installed with corner shells 4, and a chamber is provided in the middle of the power bank 1, and an adjustment mechanism for synchronously driving the adjustment block 12 to move is installed in the chamber.

[0021] In this embodiment, the adjustment mechanism includes a rotating plate 6, a rotating shaft 8 and multiple pull ropes 14. A plurality of wiring holes connected to the positioning groove 2 are provided on the inner ring surface of the chamber. One end of the pull rope 14 is installed on the rotating plate 6, and the other end passes through the wiring hole and is installed on the adjustment block 12. The rotating shaft 8 is installed at the center of the rotating plate 6. Ball bearings are embedded on both side surfaces of the chamber opposite to the rotating shaft 8. Both ends of the rotating shaft 8 are installed in the inner ring of the ball bearing. A driving mechanism for driving the rotating plate 6 to rotate is installed on one side of the power bank 1.

[0022] In this embodiment, the driving mechanism includes a worm gear 7, a worm 9, a sealed bearing 11, a shaft 10 and a handwheel 5. The worm gear 7 is installed at one end of the rotating shaft 8. One side of the power bank 1 is provided with an axial hole connected to the chamber. The worm 9 is arranged on one side of the worm gear 7 and is meshed with the worm gear 7. One end of the shaft 10 is installed on the worm 9, and the other end extends to the outside through the axial hole and is fixedly connected to the handwheel 5. The sealed bearing 11 is installed in the opening outside the axial hole, and the inner ring of the sealed bearing 11 is installed on the outer wall surface of the shaft 10.

[0023] In this embodiment, the width of the assembly block 13 is greater than the width of the positioning opening 3, and the top surface of the assembly block 13 is arranged in contact with the top surface of the positioning groove 2, so that the assembly block can only move along the top surface of the positioning groove, avoiding direct separation from the positioning opening and increasing stability after installation.

[0024] In this embodiment, the top surface of the corner shell 4 forms a display port for exposing the screen of the mobile phone. After the mobile phone is clamped inwardly by the corner shell, the screen of the mobile phone can be exposed to avoid obstruction. The corner shell is arranged at the corner of the mobile phone to avoid affecting the holding of the mobile phone due to increasing the horizontal width of the mobile phone.

[0025] When in use, first select different corner shells according to the model of the mobile phone. When disassembling the corner shell, the shaft rod can be rotated by the hand wheel. The rotation of the shaft rod drives the worm gear, and the rotation of the worm gear drives the rotating shaft and the rotating plate, so that the pull rope wound on the rotating plate can be released, so that the adjusting block can move downward along the positioning groove. After the adjusting block is moved out of the positioning groove, the assembly block under the corresponding corner shell can be inserted into the assembly groove. After rotating the hand wheel in the opposite direction, the pull rope can be rolled up on the rotating plate, and the adjusting block can be pulled inward synchronously, so that the adjusting block drives the assembly block to be pulled into the positioning groove again, and the assembly block can be restricted in the positioning groove by the inner wall surface of the positioning groove;

[0026] After the mobile phone is placed on the surface of the power bank, the hand wheel can be rotated again to make the corner shell move inward again until the corner shell is clamped and fixed on the corner of the mobile phone, and the moved corner shell can be locked in place through the worm gear and worm, so as to increase the connection firmness between the power bank and the mobile phone.

[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
