The upper rack 31 is provided on the right side of the rotating gear, and the lower rack 41 is provided on the left side of the rotating gear. The upper rack 31 and the lower rack 41 are meshed with the rotating gear at the same time. Two upper telescopic elastic members 32 are provided in the housing 1. Two elastic fixing rods 35 are provided on the upper telescopic member. One end of the upper telescopic elastic member 32 is fixed to the housing 1, and the other end is fixedly sleeved with the elastic fixing rod 35 of the upper telescopic member 3. When the upper telescopic member 3 is pulled up (or the lower telescopic member 4 is pulled down) so that the rotating gear rotates counterclockwise, the upper rack 31 is engaged with the rotating gear. The bar 31 moves upward relative to the shell 1, and the lower rack 41 moves downward relative to the shell 1, that is, the upper telescopic member 3 moves upward in the shell 1, and the lower telescopic member 4 moves downward in the shell 1, so that a storage space for a mobile phone can be easily placed. When the mobile phone is placed between the upper telescopic member 3 and the lower telescopic member 4, the upper telescopic member 3 (or the lower telescopic member 4) is released, and the upper telescopic member 3 moves into the shell 1 under the action of the upper telescopic elastic member 32, so that the rotating gear rotates clockwise, driving the lower telescopic member 4 to move toward the shell 1, thereby clamping the upper and lower parts of the mobile phone at the same time, and realizing the clamping and fixing of the mobile phone.

[0028] like Figure 4-6 As shown, the switch key 51 includes a rotating vertical rod 511 and a rotating cross rod 512, the housing 1 is provided with a switch hole 11 adapted to the rotating cross rod 512, the locking assembly 5 also includes a locking bolt 55 and a rotating plate 56, the rotating plate 56 is provided with a limiting hole 561, the limiting hole 561 is adapted to the size of the rotating cross rod 512, the rotating cross rod 512 is provided with a screw hole 5121 adapted to the locking bolt 55, when assembling, the rotating cross rod 512 is passed through the outer side of the housing 1, and the locking assembly 5 also includes a locking bolt 55 and a rotating plate 56, the rotating plate 56 is provided with a limiting hole 561, the limiting hole 561 is adapted to the size of the rotating cross rod 512, and the rotating cross rod 512 is provided with a screw hole 5121 adapted to the locking bolt 55. The switch key 51 is inserted into the switch hole 11, at which time the rotating vertical rod 511 is located outside the shell 1, and then the limiting hole 561 of the rotating plate 56 is sleeved on the rotating cross bar 512, and then the locking bolt 55 is inserted into the screw hole 5121 from the inside of the shell 1, and the switch key 51 is fixed to the shell 1 by the locking bolt 55. The diameter of one end of the locking bolt 55 is set to be larger than the diameter of the limiting hole 561, so as to ensure that the switch key 51 and the rotating plate 56 are effectively fixed to the shell 1.

[0029] Specifically, at least one rod stop surface 5122 is provided on the rotating cross bar 512, and at least one limit stop surface 5611 is provided on the limit hole 561. The rod stop surface 5122 is adapted to the limit stop surface 5611.

[0031] like Figure 7As shown, one end of the rotating track 562 is k1 and the other end is k2, the push-down switch protrusion 563 includes a locking end 564 and an unlocking end 565, the distance between the locking end 564 and the center of the limiting hole 561 is greater than the distance between the unlocking end 565 and the center of the limiting hole 561, and the outer peripheral surface of the push-down switch protrusion 563 is arc-shaped, that is, the path of the outer peripheral arc of the push-down switch protrusion 563 from the unlocking end 565 to the locking end 564 is a path in which the distance from the center point of the limiting hole 561 gradually increases.

[0032] like Figure 4 , Figure 8 As shown, in order to prevent the mobile phone from sliding due to the vibration of the bracket, an upper concave sleeve 33 is provided at one end of the upper telescopic member 3, and an upper anti-skid pad 34 is attached to the inner wall of the upper concave sleeve 33; a lower concave sleeve 43 is provided at one end of the lower telescopic member 4, and a lower anti-skid pad 44 is attached to the inner wall of the lower concave sleeve 43. Friction-increasing protrusions are provided on the surfaces of the upper anti-skid pad 34 and the lower anti-skid pad 44, which play an anti-skid role when clamping the four corners of the mobile phone.

[0033] like Figure 8 As shown, a shock absorbing plate 7 is provided on one side of the shell 1, a shock absorbing mounting column 13 is provided on the shell 1, a shock absorbing hole 72 is provided on the shock absorbing plate 7, an I-shaped shock absorbing rubber 71 is sleeved on the shock absorbing hole 72, and the shock absorbing hole 72 sleeved with the I-shaped shock absorbing rubber 71 is sleeved on the shock absorbing mounting column 13, so that the shock absorbing plate 7 is fixed on the shell 1. In this embodiment, four shock absorbing plates 7, shock absorbing mounting columns 13 and I-shaped shock absorbing rubber 71 are provided and distributed around the shell 1. The shock absorbing plate 7, shock absorbing mounting columns 13 and I-shaped shock absorbing rubber 71 act together on the shell 1 to reduce the vibration intensity around the shell 1, reduce the impact of vibration during riding an electric vehicle or a bicycle and safety considerations, and protect the mobile phone.

[0034] Here’s how it works:

[0035] When the unlocking end 565 of the push-down switch protrusion 563 is located directly above the vertical locking plate 532, the upper telescopic member 3 and the lower telescopic member 4 are in a free state and can be pulled in the up and down directions at any time;

[0036] like Fig. 9As shown, when the rotating vertical rod 511 rotates with the rotating cross rod 512 as the axis so that the rotating plate 56 rotates counterclockwise together, the unlocking end 565 gradually moves away from the top of the vertical locking plate 532, while the locking end 564 gradually approaches the top of the vertical locking plate 532. Since the distance from the unlocking end 565 to the locking end 564 and the center point of the limiting hole 561 of the outer arc surface of the pressing switch protrusion 563 gradually increases, at this time, the outer arc surface of the pressing switch protrusion 563 gradually squeezes the vertical locking plate 532, and the vertical locking plate 532 is forced to move downward, and the inclined downward pressing surface 5321 is pressed to the inclined force-bearing surface 5311, and the horizontal locking plate 531 is forced to move to the upper rack 31 under pressure until the locking end 564 is located above the vertical locking plate 532. At this time, the latch tooth 54 meshes with the upper rack 31 to achieve locking of the position of the upper rack 31, thereby achieving locking of the rotating gear, the lower rack 41 and the mobile phone placed in the upper telescopic member 3 and the lower telescopic member 4;

[0037] like Fig.10 As shown, when the rotating vertical rod 511 rotates with the rotating horizontal rod 512 as the axis so that the rotating plate 56 rotates clockwise together, the locking end 564 gradually moves away from the top of the vertical locking plate 532, and the unlocking end 565 gradually moves closer to the top of the vertical locking plate 532. Since the distance from the locking end 564 to the unlocking end 565 and the center point of the limiting hole 561 on the outer peripheral arc surface of the pressing switch protrusion 563 gradually decreases, at this time, the outer peripheral arc surface of the pressing switch protrusion 563 gradually moves away from the vertical locking plate 532, and the vertical locking plate 532 has a gap. The locking cam 531 is in a state of being moved away from the upper rack 31 and the lower rack 31 is in a state of being moved away from the lower rack 31.
