There are two groups of clamping assemblies 2, and the two groups of clamping assemblies 2 are connected by a gear transmission mechanism 3, and the two groups of clamping assemblies 2 are respectively arranged at both ends of the housing 1. The reset assembly 4 is arranged between the clamping assembly 2 and the housing 1. When the clamping assembly 2 is pulled out towards both ends, the reset assembly 4 is stretched, and a restoring force is applied to the clamping assembly 2. The fixing mechanism 5 is arranged between the gear transmission mechanism 3 and the clamping assembly 2, and the fixing mechanism 5 is used to limit the rotation of the gear transmission mechanism 3.

[0039] Refer to Figure 4As shown in the figure, the specific fixing mechanism 5 includes a locking switch 51, an engaging block 52 and an elastic member 53. The locking switch 51 is hinged in the receiving groove 121 for pushing the engaging block 52 to displace. The engaging block 52 is movably arranged between the locking switch 51 and the gear transmission mechanism 3. The engaging block 52 is engaged with the gear transmission mechanism 3 under the push of the locking switch 51. The elastic member 53 is arranged between the engaging block 52 and the second stopper 123 for pushing the engaging block 52 to reset after the locking switch 51 releases the abutment with the engaging block 52.

[0040] See Figures 5-6 As shown in the figure, more specifically, the locking switch 51 includes a rotating head 511 located in the receiving groove 121 and an extension part 512 connected to the rotating head 511 and extending to the outside of the housing 1. A limiting groove 513 for limiting the rotation angle is provided at one end of the rotating head 511 away from the extension part 512. The middle of the limiting groove 513 is divided into a first groove 5132 and a second groove 5133 by a partition bar 5131. The partition bar 5131 is made of rubber material and has elasticity. The first groove 5132 and the second groove 5133 have the same structure. Extension columns 514 for limiting the rotation direction are provided at both ends of the rotating head 511. The extension columns 514 are located in the extension groove 125.

[0041] See Figure 9 As shown in the figure, specifically, engaging teeth 521 and inclined ends 522 are respectively provided at both ends of the engaging block 52. An elastic groove 523 for accommodating the elastic member 53 is provided in the middle of the engaging block 52. After installation, the second stopper 123 is located in the elastic groove 523, and the elastic member 53 is located between the second stopper 123 and the elastic groove 523.

[0042] See Figures 7-8 As shown in the figure, specifically, the housing 1 is composed of an upper housing 11 and a lower housing 12. The upper housing 11 is provided with a limiting post 111 adapted to the first groove 5132. The lower housing 12 is provided with a receiving groove 121 for accommodating the rotating head 511, a first stopper 122 for limiting the displacement direction of the engaging block 52, a second stopper 123 for limiting the displacement distance of the engaging block 52, and a clamping limiting post 124 for limiting the displacement of the clamping assembly 2. The receiving groove 121 penetrates the lower housing 12, and extension grooves 125 adapted to the extension columns 514 are provided at both ends of the receiving groove 121.

[0043] See Figure 10As shown in the figure, the clamping assembly 2 includes a clamping head 21 for clamping one end of the mobile phone and a clamping arm 22 perpendicular to the clamping head 21. An opening slot 221 is provided in the middle of the clamping arm 22, and a rack 222 meshing with the gear transmission mechanism 3 is provided at one end of the opening slot 221. A longitudinal slot 223 is also provided on the clamping arm 22, and the longitudinal slot 223 is used to guide the clamping arm 22. When the clamping arm 22 is displaced, under the guiding action of the longitudinal slot 223, the clamping arm 22 moves in a fixed direction.

[0044] See Figure 11 As shown in the figure, specifically, the gear transmission mechanism 3 includes a large gear 31 adapted to the engagement block 52 and a small gear 32 for connecting two sets of clamping assemblies 2. The large gear 31 and the small gear 32 are integrally formed.

[0045] See Figure 4 As shown in the figure, specifically, the reset assembly 4 includes two reset blocks 41 respectively located at both ends of the clamping arm 22. A reset post 42 located on the lower housing 12 and arranged in parallel with the reset block 41. A reset elastic member 5343 for connecting the reset block 41 and the reset post 42. When the clamping assembly 2 is pulled outwards at both ends, the reset elastic member 5343 is stretched, and a restoring force is applied to the clamping arm 22.

[0046] The working principle of the present utility model: The initial state of the mobile phone holder of the present utility model is a contracted state. When the user uses it, by applying an outward pulling force to two clamping assemblies 2 or one of the clamping assemblies 2, the clamping assembly 2 moves outwards. Specifically, when the clamping arm 22 moves outwards, the rack 222 drives the gear transmission mechanism 3 to rotate, and at the same time, the reset elastic member 5343 is stretched. When the external force applied to the clamping arm 22 is released, the clamping assembly 2 is reset under the action of the reset elastic member 5343 or clamps the mobile phone placed between the two clamping heads 21. Then, the extension part 512 is pulled to make the rotating head 511 rotate around the extension column 514, so that the limiting column 111 moves from the first slot 5132 to the second slot 5133. The rotating head 511 pushes the engagement block 52 to move forward, and the engagement teeth 521 are engaged with the large gear 31 to lock the rotation of the gear transmission mechanism 3. At the same time, the elastic member 53 located between the elastic slot 523 and the second stop 123 is squeezed.

[0047] When the user needs to release the clamping of the mobile phone by the clamping component 2, the extension part 512 is pulled to make the rotating head 511 rotate around the extension column 514, so that the limit column 111 moves from the second groove 5133 to the first groove 5132. The rotating head 511 releases the abutment with the inclined end 522 and moves backward. The originally compressed elastic member 53 resets and pushes the engaging block 52 to move to release the engagement with the large gear 31. Finally, the user applies an outward pulling force to the two clamping components 2 or one of the clamping components 2, so that the clamping component 2 moves outward to take out the mobile phone from the mobile phone holder.

[0048] As described above, it is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
