DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 4 A portable mobile phone holder comprises a shell 6, two first connecting shafts 13 are rotatably connected inside the shell 6, a connecting rod 8 is installed on the side of each first connecting shaft 13, arc grooves 7 are symmetrically opened on both sides of the shell 6, one end of each connecting rod 8 passes through the arc groove 7 and extends to the outside of the shell 6, when the mobile phone is clamped, the connecting rod 8 can rotate along the arc groove 7, and the position of the connecting rod 8 can be adjusted according to the size of the mobile phone.

[0026] like Figure 1 As shown, two connecting blocks 19 are symmetrically installed at the bottom of the housing 6, and U-shaped seats 4 are installed on the side ends of the connecting blocks 19 and the two connecting rods 8. The interior of each U-shaped seat 4 is rotatably connected to a limiting column 3, and the limiting column 3 extends to one side of the housing 6, as shown in FIG. Figure 4 As shown, when clamping the mobile phone, the four limiting columns 3 can clamp the three sides of the mobile phone, so that the mobile phone can be kept stable. Figure 4 As shown, the two limiting posts 3 at the bottom of the housing 6 are located on both sides of the mobile phone charging port, so that the charging of the mobile phone will not be hindered when in use.

[0027] It should be noted that the cross section of the limiting column 3 is an "I" shape, and the outer surface of the limiting column 3 is made of rubber material. The side edge of the mobile phone can be located in the side depression of the limiting column 3, so that when the mobile phone is clamped, the mobile phone will not fall off, and under the buffer protection of the rubber material, the mobile phone screen will not be damaged due to excessive squeezing force;

[0028] like Figure 3As shown, a worm 11 is rotatably connected inside the housing 6, and a second connecting shaft 23 is rotatably connected to the end of the housing 6. A turbine 10 is installed on the side of the second connecting shaft 23, and the worm 11 is meshed with the turbine 10. A second gear 22 is installed on the side of the second connecting shaft 23. A first gear 12 is installed on the side of each first connecting shaft 13, and the two first gears 12 are meshed with each other, and the second gear 22 is meshed with one of the first gears 12. By rotating the worm 11, the second gear 22 can be driven to rotate under the action of the turbine 10, and then the two first gears 12 can be controlled to synchronously reverse with each other, driving the connecting rod 8 to rotate along the arc groove 7, and then the limit column 3 connected to the connecting rod 8 is controlled to move, and the mobile phone placed on the housing 6 is clamped. The clamping force is moderate and will not cause excessive force on the mobile phone.

[0029] It should be noted that the worm 11 and the worm gear 10 can achieve self-locking with cooperation, so that when the mobile phone is clamped, the limit column 3 will not be separated from the side of the mobile phone due to the force applied to the mobile phone, so that the mobile phone will not fall off the housing 6.

[0030] like Figure 2 As shown, a screw rod 9 is installed on one side of the shell 6, and a connecting frame 18 is sleeved on the screw rod 9. A tightening knob 20 is threadedly connected to the side of the screw rod 9. The end of the connecting frame 18 is located between the tightening knob 20 and the shell 6, and the side of the tightening knob 20 is connected to the side of the connecting frame 18. In this way, the shell 6 can be controlled to rotate relative to the connecting frame 18, and the rotation angle of the mobile phone can be adjusted. After the adjustment, the tightening knob 20 is rotated, and the connecting frame 18 and the shell 6 can be fixed together through the tightening knob 20, so that the mobile phone will not shake relative to the connecting frame 18 when in use.

[0031] A support base 17 is provided at the bottom of the connecting frame 18. The support base 17 is a "U"-shaped structure, and the end of the support base 17 close to the opening is rotatably connected to the side of the connecting frame 18. By adjusting the angle between the support base 17 and the connecting frame 18, the outer shell 6 can be supported, and the inclination angle of the outer shell 6 can be adjusted while providing miscellaneous support, thereby improving the use effect.

[0032] like Figure 1 As shown, grooves 21 are provided on both sides of the connecting frame 18, and a support rod 16 is rotatably connected inside each groove 21. The end of each support rod 16 is vertically connected to a limiting block 25. A number of limiting grooves 15 are equidistantly provided on both sides of the support base 17. When supporting, each limiting block 25 extends into the corresponding limiting groove 15. In this way, after adjusting the angle between the connecting frame 18 and the support base 17, the limiting block 25 on the support rod 16 can be moved into the corresponding limiting groove 15 to fix the support base 17 and the connecting frame 18. In this way, when in use, the housing 6 and the mobile phone placed on the housing 6 can be kept at a preset angle.

[0033] It should be noted that if Figure 2 As shown, after the support base 17 is folded up, the limiting block 25 will move into the corresponding limiting groove 15 and will not cause any obstruction to the support base 17 .

[0034] like Figure 1 As shown, a magnetic block 14 is installed at one end of the support base 17, and the magnetic block 14 is adsorbed on the side of the shell 6. When it needs to be carried, the support base 17 can be rotated to the side of the shell 6 so that the magnetic block 14 is adsorbed on the shell 6. This can reduce the space occupied by the shell 6 and the support base 17, making it easier to carry.

[0035] like Figure 1 As shown, a cover plate 2 is provided at the opening of the shell 6, the cover plate 2 is fixed on the shell 6, and a plurality of first receiving grooves 1 are provided on the side of the cover plate 2, and a plurality of second receiving grooves 24 corresponding to the first receiving grooves 1 are provided at the edge of the shell 6, and each limiting column 3 is placed in the corresponding first receiving groove 1 and the second receiving groove 24. When it is necessary to carry, the user can move the connecting rod 8 to the end of the arc groove 7 so that the limiting column 3 is aligned with the first receiving groove 1 and the second receiving groove 24. Then the user rotates the limiting column 3, and the limiting column 3 can be rotated into the first receiving groove 1 and the second receiving groove 24. In this way, the space occupied by the shell 6 and the limiting column 3 can be reduced, making it convenient to carry.

[0036] It should be noted that there is a certain distance between the end of the limiting column 3 and the end of the first receiving groove 1, so that when the mobile phone needs to be placed, the user inserts a finger into the distance to hook out the limiting column 3, which is convenient to use.

[0037] Specifically, when the utility model is used, Figure 4 As shown, the user places the mobile phone on the cover plate 2 so that the bottom of the mobile phone contacts the limiting column 3 at the bottom of the housing 6, and then the user rotates the worm 11, which drives the turbine 10 to rotate, and then the two first connecting shafts 13 can be controlled to reverse with each other under the action of the first gear 12 and the second gear 22, and then the two connecting rods 8 are controlled to rotate along the arc groove 7, so that the limiting columns 3 connected to the connecting rods 8 are against both sides of the mobile phone, clamping and fixing the mobile phone to prevent the mobile phone from falling off. When it is necessary to carry it, the staff reverses the worm 11 to restore the two connecting rods 8 to their original positions. After that, the limit column 3 is moved to the first accommodating groove 1 and the second accommodating groove 24, and then the limit block 25 on the support rod 16 is moved out of the limit groove 15, and then the support rod 16 is released. Under the action of gravity, the support rod 16 and the limit block 25 are all moved into the groove 21, and then the support base 17 is rotated, and the support base 17 is put on the connecting frame 18, and one end of the support base 17 is in contact with the shell 6, and is adsorbed on the shell 6 through the magnetic block 14, which can be folded, reducing the space occupied by the mobile phone holder and making it easy to carry.

[0038] Furthermore, Figure 1 As shown, the top of the worm 11 extends to the outside of the housing 6, and a handle 5 is installed at the end of the worm 11. The staff can control the rotation of the worm 11 by rotating the handle 5, thereby controlling the movement of the two connecting rods 8, which is easy to use.
