[0048] In the embodiment, first interface 3 is USB interface, second interface 4 is Type-C female interface, third interface 5 is Type-C male interface, and fourth interface 6 is lightning interface.The second interface 4 and the third interface 5 of the embodiment belong to the same kind of interface, and the first interface 3, the second interface 4 and the fourth interface 6 belong to different kinds of interfaces.

[0049] The third interface 5 and the fourth interface 6 are directly connected with the storage mainboard 92, and data can be directly transmitted to the storage mainboard 92 when the third interface 5 or the fourth interface 6 is directly connected with an external device. The first interface 3 needs to be connected with the storage mainboard 92 after the second interface 4 and the third interface 5 are connected. The types of the first interface 3 and the second interface 4 are different, so a conversion mainboard 91 needs to be arranged between the first interface 3 and the second interface 4 to convert the signal of the first interface 3 into the signal of the second interface 4.

[0051] Referring to the accompanying drawings Figure 5 (a), Figure 5 (b), and Figure 5 (c), first press the first rotating shaft, move the second shell to the second position, and then rotate the second shell 2 to an appropriate angle to facilitate the insertion of the third interface 5 into the external device to complete data transmission.

[0052] Referring to the accompanying drawings Figure 6 (a), Figure 6 (b), and Figure 6 (c), when the first interface 3 is inserted into an external device (such as a computer), the third interface 5 needs to be inserted into the second interface 4 first, so that the first interface 3 can convert the data received by the USB interface into data that can be received by the Type-C interface through the conversion mainboard 91, and then transmit the converted data to the storage mainboard 92 through the second interface 4 and the third interface 5.

[0053] As an example, the first shell 1 has a base 11, a first clamping plate 12, and a second clamping plate 13, the first interface 3 and the second interface 4 are arranged on opposite sides of the base 11, the second interface 4, the first clamping plate 12, and the second clamping plate 13 are arranged on the same side of the base 11, the first clamping plate 12 and the second clamping plate 13 are arranged in an interval along a second direction, and the second interface 4 and the second shell 2 are arranged in the interval between the first clamping plate 12 and the second clamping plate 13. The first sliding groove 191 is arranged on one of the first clamping plate 12 and the second clamping plate 13, and one side of the second shell 2 along the second direction is provided with the first rotating shaft 291.

[0054] The base 11 is a square block in this embodiment, and the base 11 has an inner cavity. The inner cavity of the base 11 has a first opening and a second opening. The first opening is arranged on one side of the base 11 in a first direction, and the second opening is arranged on the other side of the base 11 in the first direction. The first connector is arranged in the first opening, and the second connector 4 is arranged in the second opening. The conversion mainboard 91 is arranged in the inner cavity of the base 11.

[0055] More specifically, the base 11 further includes an interface shell 14 in this embodiment. The interface shell 14 is made of plastic. The interface shell 14 is installed in the inner cavity of the base 11. The interface shell 14 has a cavity. The cavity has a first installation opening and a second installation opening arranged on opposite sides thereof. The first installation opening is communicated with the first opening, and the second installation opening is communicated with the second opening. The first connector 3 is installed in the first installation opening, and the second connector 4 is installed in the second installation opening.

[0056] The second shell 2 is a long strip block in this embodiment. The second shell 2 has an inner cavity. The inner cavity of the second shell 2 has a third opening and a fourth opening arranged on opposite sides thereof. The third connector 5 is installed in the third opening, and the fourth connector 6 is installed in the fourth opening. The storage mainboard 92 is installed in the inner cavity of the second shell 2.

[0057] Specifically, the second shell 2 includes a first sub-shell 201 and a second sub-shell 202 in this embodiment. The first sub-shell 201 and the second sub-shell 202 enclose the inner cavity of the second shell 2. The third opening is arranged on the first sub-shell 201, and the fourth opening is arranged on the second sub-shell 202. The first sub-shell 201 and the second sub-shell 202 are connected into an integral whole by adhesion.

[0058] The base 11, the first clamping piece 12, and the second clamping piece 13 are all made of metal. The first clamping piece 12 and the second clamping piece 13 have a certain elasticity and a tendency to approach each other. When installed, the second shell 2 can be inserted into the gap between the first clamping piece 12 and the second clamping piece 13. After the second shell 2 is inserted, the first clamping piece 12 and the second clamping piece 13 clamp the second shell 2 to prevent the second shell 2 from falling off the gap between the first clamping piece 12 and the second clamping piece 13.

[0059] Referring to Figure 2 and Figure 3 , and referring to Figures 7 to 10 , as an example, the first sliding groove 191 is arranged on the first clamping piece 12. The second clamping piece 13 is provided with a second sliding groove 192. The second sliding groove 192 penetrates the second clamping piece 13 along the second direction. The second sliding groove 192 is parallel to the first sliding groove 191.

[0060] The second clamping piece 13 is provided with a second rotating shaft 292, which slides in the second sliding groove 192, so that the second rotating shaft 292 slides in the second sliding groove 192 and rotates around its own axis.

[0061] In the embodiment, the first sliding groove 191 and the second sliding groove 192 are opposite to each other, and the length of the first sliding groove 191 is the same as the length of the second sliding groove 192.

[0062] In the embodiment, the first sliding groove 191 does not penetrate the first clamping piece 12, that is, the depth of the first sliding groove 191 is smaller than the thickness of the first clamping piece 12 in the second direction. However, the second sliding groove 192 penetrates the first clamping piece 12 in the second direction, so that the second rotating shaft 292 is built in the second sliding groove 192. A hand can push the second shell 2 or the second rotating shaft 292 in the second sliding groove 192, so as to drive the second shell 2 to rotate or slide.

[0063] Referring to Figure 2 and Figure 3 , and referring to Figures 7 to 10 , as an example, the first clamping piece 12 is provided with a first guide column on the side close to the second clamping piece 13, the surface of the base 11 is provided with a first guide groove 21 and a second guide groove 22, the first guide groove 21 is arranged around the first rotating shaft 291, the second guide groove 22 is a straight groove, one end of the second guide groove 22 is communicated with the first guide groove 21; when the first rotating shaft 291 slides between the first position and the second position, the first guide column slides along the second guide groove 22; when the first rotating shaft 291 rotates around its own axis at the second position, the first guide column slides in the first guide groove 21.

[0064] In the embodiment, the cooperation of the first guide column with the first guide groove 21 and the second guide groove 22 is mainly used to limit the trajectory of the second shell 2. Specifically, when the second shell 2 is located at the second position and rotates around the first rotating shaft 291, the first guide column is located in the first guide groove 21 and rotates in the annular first guide groove 21. The first guide column enables the second shell 2 to rotate stably and avoids deviation during rotation.

[0065] When the second shell 2 slides towards or away from the base 11, the second guide groove 22 and the first sliding groove 191 are parallel due to the rotation of the second shell 2, so that the first guide column can enter the second guide groove 22 from the first guide groove 21 and slide along the second guide groove 22, thereby realizing repeated sliding between the first position and the second position.

[0066] Referring to Figure 2 and Figure 3 , and referring to Figures 7 to 10 , as an example, the first clamping piece 12 is provided with a first ball convex 15 on the side close to the second clamping piece 13, and the first ball convex 15 and the first guide column are arranged in a first direction; the second shell 2 is provided with a circular first blind hole on the side surface close to the first clamping piece 12, the first blind hole is provided with a first limiting disc 23, the first limiting disc 23 and the side wall of the first blind hole surround the first guide groove 21, the first limiting disc 23 is provided with a plurality of first limiting holes 25, the plurality of first limiting holes 25 are distributed around the first rotation axis 291, the first blind hole, the first limiting disc 23 and the first rotation axis 291 are coaxial, when the second shell 2 is located at the second position and rotates around the first rotation axis 291, the ball convex can be clamped into any one of the first limiting holes 25.

[0067] In the embodiment, when the second shell 2 is located at the second position and rotates in place around the first rotation axis 291, as the second shell 2 gradually rotates, the ball convex can be clamped from one first limiting hole 25 to another first limiting hole 25, when the ball convex is clamped into one of the first limiting holes 25, without the action of external force, the angle of the second shell 2 relative to the first shell 1 at this time can be maintained.

[0068] In the embodiment, due to the existence of the first guide groove 21, the first guide column can also be limited from sliding towards the base 11 during rotation. In other words, when the second shell 2 is located at the second position and rotates in place, at this time, the first guide column is located in the first guide groove 21, when the first guide column is subjected to a force towards the base 11 but the second guide column does not move to the position where the first guide groove 21 and the second guide groove 22 are connected, during this process, the first guide column abuts against the side wall of the first limiting disc 23, and the first limiting disc 23 can limit the movement of the first guide column towards the base 11.

[0069] The interval distance between the first position and the second position in the embodiment is less than the length of the first sliding groove. In the embodiment, when the first rotation axis 291 is located at the first position, at this time, the first rotation axis 291 is located at one end of the first sliding groove 191, when the first rotation axis 291 is located at the second position, at this time, the first rotation axis 291 does not reach the other end of the first sliding groove 191, that is, when the first rotation axis 291 is at the second position, the side wall of the first rotation axis 291 and the side wall of the two ends of the first sliding groove 191 are spaced apart.

[0070] Although the length of the first sliding groove 191 is such that the first rotating shaft 291 does not abut against the side wall of the end of the first sliding groove 191 when in the second position, the side wall of the first limiting disc 23 is present, so the first rotating groove and the second rotating groove can still be limited to move between the first position and the second position.

[0071] In actual processing, if the interval distance between the first position and the second position is exactly equal to the length of the first sliding groove 191, the processing difficulty is great and the cost is high, so the length of the first sliding groove 191 is slightly increased to facilitate assembly and reduce production cost.

[0072] When the first guide column needs to move towards the base 11, the second housing 2 is rotated so that the first guide column is located at the position where the first guide groove 21 and the second guide groove 22 are connected, at this time, a force is applied to the first guide column to move towards the base 11, which can drive the first guide column into the second guide groove 22, thereby realizing the reciprocating movement of the second housing 2 in the first direction.

[0073] Referring to Figure 2 and Figure 3 and referring to Figures 7 to 10 , as an example, the second clamping piece 13 is provided with a second guide column on the side close to the first clamping piece 12, the surface of the base 11 is provided with a third guide groove 26 and a fourth guide groove 27, the third guide groove 26 is arranged around the second rotating shaft 292, the fourth guide groove 27 is a straight groove, one end of the fourth guide groove 27 is connected to the third guide groove 26, and the fourth guide groove 27 is parallel to the second guide groove 22; when the second rotating shaft 292 slides between the first position and the second position, the second guide column slides along the fourth guide groove 27; when the second rotating shaft 292 rotates around its own axis in the second position, the second guide column slides in the third guide groove 26.

[0074] In this embodiment, the third guide groove 26 and the first guide groove 21 have the same structure, that is, the orthographic projection of the third guide groove 26 on the surface of the second housing 2 provided with the first guide groove 21 coincides with the orthographic projection of the bottom wall of the first guide groove 21 on the surface of the second housing 2 provided with the first guide groove 21. Similarly, the orthographic projection of the second guide groove 22 and the fourth guide groove 27 on the surface of the second housing 2 provided with the first guide groove 21 coincides. In this embodiment, the first rotating shaft 291 and the second rotating shaft 292 are coaxial, and through the above arrangement, when the second housing 2 slides or rotates, the two side surfaces of the second housing 2 can be synchronized, so that the rotating or sliding action is smooth, and the jamming phenomenon that occurs when the second housing 2 slides or rotates is reduced.

[0075] As an example, the second clamping piece 13 is provided with a second ball convex 16 on the side close to the first clamping piece 12, and the second ball convex 16 and the second guide column are arranged in the first direction at intervals; the second shell 2 is provided with a circular second blind hole on the side surface close to the first clamping piece 12, and the second blind hole is provided with a second limiting disc, the second limiting disc and the side wall of the second blind hole surround the third guide groove 26, the second limiting disc is provided with a plurality of second limiting holes 28, the plurality of second limiting holes 28 are distributed at intervals around the first rotation axis 291, the second blind hole, the second limiting disc and the first rotation axis 291 are coaxial, and when the second shell 2 is located at the second position and rotates around the axis of the second rotation axis 292, the second ball convex 16 can be clamped into any one of the second limiting holes 28.

[0076] The working principle of the second ball convex 16 is the same as that of the first ball convex 15, which will not be repeated.

[0077] Referring to Figure 3 , Figure 9 and Figure 10 , as an example, the first limiting disc 23 is provided with an avoiding groove 24, one end of the avoiding groove 24 is communicated with the first limiting hole 25, the other end of the avoiding groove 24 is communicated with the first guide groove 21, and the avoiding groove 24 is parallel to the second guide groove 22; when moving from the second position to the first position, the first ball convex 15 can enter the second guide groove 22 through the first limiting hole 25 and the avoiding groove 24 in sequence.

[0078] Referring to Figure 2 and Figure 3 , and referring to Figures 7 to 10In the embodiment, when sliding from the second position to the first position, the first ball convex 15 needs to slide from the first limiting hole 25 into the first guide slot 21, and then the first ball convex 15 enters the second guide slot 22 from the first guide slot 21. At the same time, the second ball convex 16 needs to slide from the second limiting hole 28 into the third guide slot 26, and then the second ball convex 16 enters the fourth guide slot 27 from the third guide slot 26. In the process of the first ball convex 15 entering the first guide slot 21 from the first limiting hole 25 and the second ball convex 16 entering the third guide slot 26 from the second limiting hole 28, the second ball convex 16 needs to jump from the second limiting hole 28 to the surface of the second limiting disc, and then fall into the third guide slot 26 from the surface of the second limiting disc. The avoidance slot 24 provided on the first limiting disc 23 in the embodiment can make the first ball convex 15 directly enter the first guide slot 21 along the avoidance slot 24, without the need for the first ball convex 15 to jump from the first limiting hole 25 to the surface of the first limiting disc 23, and then fall into the first guide slot 21 from the surface of the first limiting disc 23. That is, when the second shell 2 slides from the second position to the first position, due to the existence of the avoidance slot 24, when the second ball convex 16 jumps from the second limiting hole 28 to the surface of the second limiting disc, the end of the second shell 2 away from the first shell 1 will tilt towards the inclined first clamping piece 12, thereby reducing the jumping of the second ball convex 16.

[0079] If the avoidance slot 24 is not provided on the first limiting disc 23, the action of the first ball convex 15 jumping from the first limiting hole 25 to the surface of the second shell 2 and the action of the second ball convex 16 jumping to the surface of the second shell 2 will occur at the same time. The above two actions will spread the first clamping piece 12 and the second clamping piece 13 to make the first clamping piece 12 and the second clamping piece 13 move away from each other, which is extremely easy to cause the second shell 2 to be separated from the first clamping piece 12 and the second clamping piece 13, affecting the normal. Even if the second shell 2 does not separate from the first shell 1 when the first clamping piece 12 and the second clamping piece 13 are spread, when the second shell 2 slides from the second position to the first position, the user needs to increase the force applied to push the second shell 2, and the increased force is used to overcome the simultaneous jumping of the first ball convex 15 and the second ball convex 16 to the corresponding surface of the second shell 2, affecting the user's experience.

[0080] As an example, the second shell 2 further comprises a pushing member, the pushing member comprises a pushing screw 71 and a pushing block 72, the pushing screw 71 is arranged in the second sliding groove 192, one end of the pushing screw 71 is connected with the pushing block 72, the other end of the pushing screw 71 is connected with the second rotating shaft 292, the surface of the pushing block 72 away from the pushing screw 71 protrudes out of the second sliding groove 192 in the direction away from the first clamping piece 12. In this embodiment, the second sliding groove 192 is a stepped groove, the pushing block 72 is located on the side of the second clamping piece 13 away from the first clamping piece 12, and the pushing block 72 is located outside the second sliding groove 192. A user can push the pushing block 72 to drive the second shell 2 to reciprocate in the first direction.

[0081] Compared with the stepped second sliding groove 192 in the above embodiment, in other embodiments, the second sliding groove 192 does not need to be a stepped groove, the pushing block 72 is located on the side of the second clamping piece 13 away from the first clamping piece 12, and a user can directly push the pushing block 72.

[0082] In other embodiments, the second sliding groove 192 is also a stepped groove, the stepped groove comprises two grooves with different sizes, the larger groove is located on the side of the second clamping piece 13 away from the first clamping piece 12, the pushing block 72 is located in the larger groove of the second sliding groove 192, and the surface of the pushing block 72 away from the first clamping piece 12 protrudes out of the second sliding groove 192 in the direction away from the first clamping piece 12. A user can push the part exposed in the second sliding groove 192 to drive the second shell 2 to push.

[0083] As an example, the first shell 1 further comprises a protective shell and a plug-in cover 82, the protective shell is provided with a containing cavity, the plug-in cover 82 is arranged in the protective shell, the plug-in cover 82 has a plug-in cavity for containing the first interface 3, and the first interface 3 is plugged into the plug-in cover 82. In this embodiment, the protective sleeve 81 is made of metal, the plug-in sleeve is made of plastic, the plug-in sleeve is fixed in the protective sleeve 81 by adhesion, a plurality of protrusions 83 are arranged on the side wall of the plug-in cavity, the protrusions 83 are integrally formed with the plug-in sleeve, when the first interface 3 is inserted into the plug-in cavity, the plurality of protrusions 83 are in contact with the first interface 3, the first interface 3 is clamped by the plurality of protrusions 83, and the detachable connection of the first interface 3 and the plug-in cover 82 is realized by the friction force between the plurality of protrusions 83 and the first interface 3.

[0084] In this embodiment, the protective sleeve 81, the base 11, the first clamping piece 12, the second clamping piece 13, and the second shell 2 are all made of metal, and the metal material can reduce the damage to the surface of the U disk caused by collision, falling, and the like.
