[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1 to 8 As shown, the retractable scanning head financial mobile phone card holder provided by this utility model includes a mobile phone case 1, a card slot is provided on the side of the mobile phone case 1, a dust plug 2 is provided on the inner wall of the card slot, a round hole is provided on the back of the mobile phone case 1, a telescopic protective mechanism 3 is fixedly connected to the outer wall of the round hole, and an expansion connection mechanism 4 is movably sleeved at the bottom of the mobile phone case 1.

[0034] The telescopic protective mechanism 3 includes a back plate 301, an opening and closing knob 302, a baffle 303, a friction post 304, a connecting limit ring 305, a height adjustment ring 306, an adjusting threaded block 307, a threaded groove 308, a second limit post 309, a movable outer ring 310, a movable inner ring 311, a drive shaft 312, an internal gear 313, a pinion 314, and an inner cover plate 315. The connecting limit ring 305 is fixedly connected to the back of the phone case 1. The height adjustment ring 306 is movably sleeved inside the connecting limit ring 305. The movable outer ring 310 is movably sleeved inside the height adjustment ring 306. The movable inner ring 311 is fixedly connected to the inner wall of the movable outer ring 310. The back plate 301 is fixedly connected to the back of the movable inner ring 311. Several sets of drive shafts 312 are movably sleeved on the inner wall of the back plate 301. The several sets of drive shafts 312 are arranged in a circular array. The baffle 303 is fixedly connected to the outer wall of each drive shaft 312.

[0035] The inner part of the movable outer ring 310 is provided with a threaded groove 308, and an adjusting threaded block 307 is movably sleeved inside the threaded groove 308. The outer wall of the adjusting threaded block 307 is fixedly connected to the height adjusting ring 306.

[0036] By rotating the height adjustment ring 306, the adjusting threaded block 307 is driven to rotate synchronously, so that the adjusting threaded block 307 is threadedly connected to the threaded groove 308, thereby adjusting the depth of the movable outer ring 310, so that the entire device is adjusted and retracted to the outside of the scanning head, avoiding or reducing the impact on scanning.

[0037] Several sets of friction columns 304 are fixedly connected to the outer wall of the height adjustment ring 306. The friction columns 304 are arranged in a circular array with the height adjustment ring 306 as the center, and the friction columns 304 are semi-circular.

[0038] By setting several sets of friction pillars 304 on the outside of the height adjustment ring 306, the friction force when rotating the height adjustment ring 306 is increased, the surface friction force is increased, and the slippage when rotating the height adjustment ring 306 is prevented.

[0039] The inner movable outer ring 310 has four sets of limiting posts 309. The four sets of limiting posts 309 are arranged in a circular array with the inner movable ring 311 as the center. The back of the limiting posts 309 is fixedly connected to the phone case 1.

[0040] Four sets of limiting posts 309 are fitted inside the movable outer ring 310. The limiting posts 309 limit the position of the movable outer ring 310 to prevent the movable outer ring 310 from rotating synchronously with the height adjustment ring 306, thereby ensuring that the threaded groove 308 can fit onto the adjusting threaded block 307 and move it.

[0041] The outer wall of the drive shaft 312 is fixedly connected with a small gear 314, the outer wall of the small gear 314 is meshed with an internal gear 313, and the outer wall of the internal gear 313 is movably sleeved with the movable inner ring 311.

[0042] One set of drive shafts 312 drives the pinion 314 to rotate. The pinion 314 meshes with the internal gear 313, which in turn drives the other sets of drive shafts 312 to rotate synchronously, realizing the synchronous opening and closing of multiple sets of baffles 303, thereby sealing the outside of the scanning head and completing the protection of the scanning head.

[0043] The baffles 303 are arranged in a circular array, and the height of every six groups of baffles 303 increases sequentially, with each group of baffles 303 fitting together.

[0044] Through a design that raises the baffles sequentially, the baffles 303 can be stacked on top of each other as they move outward, thus achieving storage.

[0045] One of the drive shafts 312 has an opening and closing knob 302 fixedly connected to its back side, and the outer wall of the opening and closing knob 302 is in contact with the back plate 301.

[0046] The dust plug 2 includes a dustproof partition 201, a limiting post 202, and a limiting block 203. The two ends of the limiting post 202 are fixedly connected to the phone case 1. One end of the dustproof partition 201 is movably sleeved on the outer wall of the limiting post 202. The other end of the dustproof partition 201 is fixedly connected to the limiting block 203. The outer wall of the limiting block 203 is movably sleeved on the phone case 1.

[0047] If the card slot is exposed to the air for a long time, dust will easily accumulate, and dust will interfere with the reading of card information. Therefore, when not in use, the dustproof partition 201 can seal the card slot to reduce or prevent dust from entering. When a card needs to be inserted, pull the limiting card block 203, and the dustproof partition 201 will rotate synchronously around the limiting post 202 and move out to allow for card insertion.

[0048] The extended connection mechanism 4 includes a power information line 401, a connecting connector 402, an interface clamp 403, a telescopic rod 404, a spring 405, and a limiting pull plate 406. The connecting connector 402 is movably sleeved with the bottom end of the phone case 1. The side of the connecting connector 402 is fixedly connected to the power information line 401, and the top end of the power information line 401 is fixedly connected to the phone case 1. Four sets of connecting slots are opened on the side of 1. The interface clamp 403 is movably sleeved inside the connecting slots. The telescopic rod 404 is fixedly connected to both sides of the interface clamp 403. The limiting pull plate 406 is fixedly connected to the bottom end of the telescopic rod 404. The spring 405 is attached to the top end of the limiting pull plate 406. The spring 405 is arc-shaped.

[0049] When the financial mobile phone needs to expand with more auxiliary accessories to connect to one or more external devices according to commercial scenarios, the connector 402 can be plugged into the phone's charging port and connected to the phone case 1 via the power information cable 401. Then, the connection cable of the device to be connected is plugged into the four sets of connection slots on the side of the phone case 1, pushing the interface clamp 403 to move outward. At this time, the telescopic rods 404 on both sides simultaneously pull the limiting plate 406 to move upward inside the phone case 1, squeezing the spring piece 405. The spring piece 405 is made of elastic material. Made of metal or polymer materials, it is arc-shaped. When squeezed, the material undergoes elastic deformation. Under the influence of the elastic potential energy of the spring piece 405, it pushes the interface clamp 403 to clamp the connector and maintain the stability of the connection. When no other devices are plugged in, under the influence of the elastic potential energy of the spring piece 405, it pushes the limit pull plate 406 to move downward, so that the telescopic rod 404 is fitted into the inside of the phone case 1. At this time, the outer wall of the interface clamp 403 between the two sets of telescopic rods 404 is flush with the outer wall of the phone case 1, which is convenient for gripping during use.

[0050] The working principle is as follows: When in use, the financial mobile phone is placed inside the phone case 1. The phone case 1 covers the main body of the mobile phone. The scanning head and the mobile phone camera are both inside the telescopic protective mechanism 3. When it is necessary to use the scanning head to scan information, turn the opening and closing knob 302, which drives a set of transmission shafts 312 to rotate inside the back plate 301, thereby driving the pinion 314 and the baffle 303 to rotate synchronously. When the first set of pinion 314 rotates, it meshes with the inner gear 313, causing the inner gear 313 to rotate inside the movable inner ring 311. At the same time, it meshes with all the other pinion 314, driving the other pinion 314 and the baffle 303 to rotate around the transmission shaft 312 as the center, causing the baffle 303 to move outward until it is in contact with the inner wall of the movable inner ring 311. Multiple sets of baffles 303 are stacked, and the scanning head and camera are exposed to the outside, so that information can be scanned. At this time, pinch the outside of the height adjustment ring 306 and rotate it. The height adjustment ring 306 drives the internal adjusting thread block 307 and thread groove 308 to rotate, adjusting the distance between the movable outer ring 310 and the phone case 1. This allows the movable outer ring 310 to extend and retract on the outer wall of the phone case 1, which in turn adjusts the distance between the baffle 303 and the phone case 1. When using the scanning head, the telescopic protective mechanism 3 can be placed on the outside of the scanning head to reduce the impact on scanning and maintain image integrity.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
