[0026] It should be noted that according to actual use needs, magnets can be embedded on the top surface of the upper shell 2 or in the anti-slip grooves to firmly magnetically attract the mobile phone to the upper shell 2, so that the mobile phone can be placed on the base more stably; a connecting part 7 for integrally combining with the mobile phone stand is provided on the bottom surface of the base. Through the connecting part 7, the clamping mechanism of the mobile phone stand can be installed on mobile phone stands of different specifications. The connecting part 7 can be set but is not limited to a threaded block, that is, the clamping mechanism is combined with the stand through the threaded block to form a mobile phone stand for use.

[0027] In this embodiment, a rotation conversion part for realizing the relative movement between the left clamping part and the right clamping part is installed in the inner cavity of the base. The rotation conversion part includes a second guide plate 12 and a first guide plate 13 which are stacked up and down, a gear 15 located at the overlapping part of the second guide plate 12 and the first guide plate 13, a fixed seat 14 located above the gear 15 and connected to the top surface of the second guide plate 12, and a screw rod 8 that transversely passes through and is screwed to the fixed seat 14. The end of the rod body of the screw rod 8 extends out of the left side position of the left clamping part and is connected with an adjusting part 9. The screw rod 8 is located below the first guide plate 13. Among them, when the adjusting part 9 rotates, it drives the screw rod 8 to rotate in a spiral manner, so that the screw rod 8 generates a spiral driving force to drive the fixed seat 14 to move left or right; the right end of the second guide plate 12 is fixedly connected to the right clamping part, and the left end of the first guide plate 13 is fixedly connected to the left clamping part; a through hole 121 for placing the gear 15 is provided at the overlapping part of the second guide plate 12 and the first guide plate 13; among them, two groups of racks 122 meshed with the gear 15 are arranged in a mirror image in the through hole 121. One group of racks 122 is connected to the plate body of the second guide plate 12, and the arrangement direction of the racks 122 is the same as the extension direction of the plate body of the second guide plate 12. The other group of racks 122 is connected to the plate body of the first guide plate 13, and the arrangement direction of the racks 122 is the same as the extension direction of the plate body of the first guide plate 13. The top views of the second guide plate 12 and the first guide plate 13 are both rectangular structures, and the top view of the through hole 121 is a rectangular structure.

[0028] In this embodiment, the mentioned left clamping part includes a first clamping part 4 connected to the left end of the first guide plate 13, and two groups of first guide posts 10 connected to the right side of the first clamping part 4. The right ends of the column bodies of the two groups of first guide posts 10 extend into the base, and the two groups of first guide posts 10 are arranged symmetrically with the first guide plate 13 as the axis; the right clamping part includes a second clamping part 5 connected to the right end of the second guide plate 12, and two groups of second guide posts 11 connected to the left side of the second clamping part 5. The left ends of the column bodies of the two groups of second guide posts 11 extend into the base, and the two groups of second guide posts 11 are arranged symmetrically with the second guide plate 12 as the axis. The two groups of second guide posts 11 are arranged in one-to-one correspondence with the two groups of first guide posts 10; among them, the horizontal axes of the column bodies of the first guide posts 10 and the second guide posts 11 are on the same horizontal line, and a spring 101 is provided at the opposite surfaces of the column bodies of the first guide posts 10 and the second guide posts 11.

[0029] Among them, when the operating screw 8 reduces the distance between the first clamping portion 4 and the second clamping portion 5, the first guide post 10 and the second guide post 11 retract toward the center of the base cavity, and the spring 101 will be compressed. When the operation of the screw 8 loses the spiral force of the screw 8, the first guide post 10 and the second guide post 11 quickly extend smoothly toward both sides of the base under the elastic force of the spring 101; the extension and movement directions of the first guide post 10 and the first guide plate 13 are the same, and the extension and movement directions of the second guide post 11 and the second guide plate 12 are the same; among them, jacks for the spring 101 to extend into are provided at the opposite ends of the columns of the first guide post 10 and the second guide post 11.

[0030] It should be noted that through the mutual cooperation of the first guide post 10 and the first guide plate 13, the first clamping portion 4 can move smoothly to the left or right to achieve the expansion and contraction of the first clamping portion 4. By using the cooperation of the second guide post 11 and the second guide plate 12, the second clamping portion 5 can move smoothly to the left or right to achieve the expansion and contraction of the second clamping portion 5. And under the action of the gear 15 and the rack 122, the first clamping portion 4 and the second clamping portion 5 can expand and contract simultaneously to realize the relative movement of the first clamping portion 4 and the second clamping portion 5, and then complete the work of clamping or loosening the mobile phone; among them, the specification of the mobile phone clamped between the first clamping portion 4 and the second clamping portion 5 depends on the radial length set by the through hole 121 or the rack 122; among them, the mentioned rack 122 can drive the gear 15 to rotate when the first guide plate 13 or the second guide plate 12 moves left and right.

[0031] In this embodiment, rubber pads are provided on the left side of the mentioned second clamping portion 5 and the right side of the first clamping portion 4. A fastening portion 6 for pressing the second guide plate 12 not to move is provided on the right side of the second clamping portion 5. The fastening portion 6 is composed of a convex block 601 and a clamping plate 602 pinned to the convex block 601. The inner side of the plate body of the clamping plate 602 extends into the cavity of the second clamping portion 5 and is movably pressed against the second guide plate 12.

[0032] When the mobile phone holder clamping mechanism clamps a mobile phone, the mobile phone is placed on the upper housing 2, and the object supporting part 3 supports the mobile phone. Then, by rotating the adjusting part 9 clockwise, the adjusting part 9 rotates and drives the screw rod 8 to rotate clockwise in a spiral manner. At this time, under the action of the spiral driving force of the screw rod 8, the first clamping part 4, the first guide plate 13 and the first guide post 10 move together in the direction of the second clamping part 5. At this time, the rack 122 of the first guide plate 13 drives the gear 15 to rotate, that is, the gear 15 rotates counterclockwise; under the principle of meshing transmission of the gear 15, the counterclockwise rotating gear 15 then drives the rack 122 of the second guide plate 12 to move in the direction of the first clamping part 4, that is, the second guide plate 12 drives the second clamping part 5 to move in the direction of the first clamping part 4. At this time, the distance between the first clamping part 4 and the second clamping part 5 is gradually reduced, so that a clamping force is generated between the first clamping part 4 and the second clamping part 5 to achieve the purpose of clamping the mobile phone; among them, when the adjusting part 9 is rotated counterclockwise, the gear 15 rotates clockwise and drives the first guide plate 13 and the second guide plate 12 to move outwards. At this time, the first guide plate 13 drives the first clamping part 4 to move, that is, the first clamping part 4 will continuously move away from the left side wall of the base, and the second guide plate 12 drives the second clamping part 5 to move, that is, the second clamping part 5 will continuously move away from the right side wall of the base. Then, the distance between the first clamping part 4 and the second clamping part 5 is gradually enlarged, so as to achieve the purpose of loosening the clamped mobile phone; among them, the adjusting part 9 can be set but is not limited to a block in the shape of a ball, and the adjusting part 9 and the screw rod 8 can be set as an integrally connected formed structure.

[0033] Among them, when it is necessary to clamp mobile phones of different sizes according to actual needs, the second guide plate 12 and the second clamping part 5 are fastened by the fastening part 6, so that the second guide plate 12 and the first guide plate 13 are tightly pressed together. Thus, it is difficult for the first guide plate 13 and the second guide plate 12 to move and overlap, so that the adjusting part 9 cannot be rotated to move the first clamping part 4 or the second clamping part 5 any more, thereby determining the distance between the first clamping part 4 and the second clamping part 5; when the buckle plate 602 is not buckled down, the first guide plate 13 and the second guide plate 12 overlap and move together.

[0034] In summary: The utility model can pull the upper and lower halves of the first clamping part 4 in two directions through the cooperation of the No. 1 guide plate 13 and the first guide column 10, so that the first clamping part 4 can be smoothly extended and retracted on the left side of the base; with the cooperation of the No. 2 guide plate 12 and the second guide column 11, the upper and lower halves of the second clamping part 5 can be pulled in two directions, so that the second clamping part 5 can be smoothly extended and retracted on the right side of the base, and under the action of the gear 15 and the rack 122, the first clamping part 4 and the second clamping part 5 can be synchronously extended and retracted, thereby improving the overall stability of the first clamping part 4 and the second clamping part 5 during the extension and retraction process, reducing the amount of skew and shaking generated when the first clamping part 4 and the second clamping part 5 are used, reducing the contact wear of the first clamping part 4 and the second clamping part 5, and then improving the durability and toughness of the clamping mechanism, and extending the service life of the clamping mechanism.

[0035] Among them, with the cooperation of the screw 8 and the fastening part 6, the first clamping part 4 and the second clamping part 5 can be quickly operated to achieve extension and contraction, so as to adjust and determine the distance between the first clamping part 4 and the second clamping part 5, thereby adapting to the clamping work of mobile phones of different specifications, and can be used as a clamping mechanism for mobile terminal holders such as mobile phones and tablets.
