In recent years, tablet-style electronic devices such as smartphones, tablet computers, and e-book readers have become widely popular due to their diverse functions, slim and portable design. With technological advancements, these tablet-style electronic devices can now store large amounts of information, so more and more users are now accustomed to using them to read novels and magazines, or to store reference books such as sheet music and cookbooks for easy access and reading anytime.

[0003] However, the tablet-type electronic device does not have any supporting structure that can support it on a flat surface or in space. Therefore, users can only read the information on the screen and operate the tablet-type electronic device by holding it or placing it on a flat object. Over time, this can easily cause chronic injuries such as stiff fingers and cervical curvature. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a multi-purpose extended storage stand and its connector. The front end of the extended storage stand can be equipped with a shelf for electronic devices of different specifications. The shelf can be adjusted in position and angle according to usage needs and usage environment, so that the user can place the electronic device at the best viewing angle. In addition, this extended storage stand can also be used by filmmakers or music performers to install and set up their auxiliary lighting, auxiliary sound recording, etc., so that these auxiliary devices can be adjusted to be placed at the best sound recording or lighting angle.

[0005] To achieve the aforementioned objectives, the present invention employs a technical means that the connector of a multi-purpose extended shelf includes:

[0007] A first set of connectors, on which one set of terminals of the connector is formed, and the first set of connectors has a sleeve terminal and an annular groove, the annular groove being recessed into the outer wall surface of the sleeve terminal of the first set of connectors.

[0008] A socket has a socket groove, a slot and a through hole. The socket groove is recessed into a lower end face of the socket. The socket end of the first set of sockets protrudes into the socket groove. The slot extends longitudinally and penetrates an upper end face and a lower end face of the socket, and also penetrates a side face of the socket. The through hole extends laterally and penetrates the side face of the socket. A first central axis is defined in the socket groove and extends along the extension direction of the socket groove. A second central axis is defined in the through hole and extends along the extension direction of the through hole. The first central axis and the second central axis are skew to each other.

[0009] A second set of connectors, on which another set of connector ends of the connector are formed, and the second set of connectors has a set of connecting rods, which protrude laterally from the side of the second set of connectors, pass through the through hole of the connector, and pass through the annular groove along the tangent direction of the annular groove of the first set of connectors, and the connecting rods can move along the annular groove and can also rotate within the annular groove;

[0010] A knob is attached to the connecting rod of the second set of connectors, the connector being clamped between the side of the second set of connectors and the knob.

[0011] In the connector of the multi-purpose extended storage bracket, the connecting rod of the second set of connectors and the knob are threaded together.

[0012] In the connector of the multi-purpose extended storage bracket, a certain engagement surface can be further formed on the side surface of the socket, the fixed engagement surface surrounds one end of the through hole, the connecting rod of the second set of connectors extends into the through hole of the socket from the side with the fixed engagement surface, and a movable engagement surface can be further formed on the side surface of the second set of connectors, the movable engagement surface surrounds the connecting rod, and the movable engagement surface selectively engages with the fixed engagement surface of the socket.

[0013] In the connector of the multi-purpose extended storage bracket, the socket can form fixed engagement surfaces on opposite sides of its side surface. The fixed engagement surfaces surround the through hole. A washer is further provided between the socket and the knob. The connecting rod of the second set of connectors passes through the through hole of the socket and the washer in sequence. A movable engagement surface is further formed on the side surface of the second set of connectors. The movable engagement surface surrounds the connecting rod and selectively engages with the fixed engagement surface of the socket.

[0014] In the connector of the multi-purpose extended storage bracket, a full-line loop can be further provided on the side of the socket.

[0015] To achieve the aforementioned objectives, another technical means employed in this invention is to provide a multi-purpose extended storage rack comprising:

[0016] An extension assembly having two ends and including at least one of the aforementioned connectors and at least one extension rod, the connector and the extension rod being arranged alternately and connected to each other, each extension rod having two connecting ends, and at least one connecting end of each extension rod being connected to the connecting end of at least one connector.

[0017] A clamp is attached to one of the terminals of the extension assembly.

[0018] In the aforementioned multipurpose extended storage bracket, the clamp can be assembled to the assembly end formed on the first assembly seat of the connector located at the end of the extended assembly.

[0019] In the aforementioned multi-purpose extended storage bracket, the connector can include multiple connectors, and the two ends of the extension rod located between two connectors are respectively connected to the first connection seat of one connector to form a connection end and connected to the second connection seat of the other connector to form a connection end.

[0020] In the aforementioned multi-purpose extended storage bracket, a full-line loop can be further provided on the side of the socket.

[0021] With the design described above, a shelf, lamp, or radio device for mounting a tablet electronic device can be connected to the extension assembly. When the knob is turned to loosen the socket relative to the socket end of the first set of sockets, the user can rotate the second set of sockets and the socket around the socket end of the first set of sockets. This also causes the second set of sockets and the extension rod connected to them to rotate laterally relative to the socket and the first set of sockets, allowing the extension rod to rotate within the annular groove. This adjusts the angle and direction of the extension rod connected to the second set of sockets, allowing the user to adjust the shelf with the tablet electronic device to a comfortable viewing height and angle, or to allow filmmakers or music performers to install and set up auxiliary lighting, auxiliary sound recording, and other auxiliary equipment, adjusting these auxiliary equipment to the optimal sound recording or lighting position.

[0050] See Figure 1 and Figure 2 As shown, the multi-purpose extended storage bracket of the present invention includes an extension component AA and a clamp BB.

[0051] The extension component AA is a long frame with two ends. The extension component AA includes at least one connector 10A, 10B and at least one extension rod 20A, 20B. The connector 10A, 10B and the extension rod 20A, 20B are arranged alternately and connected to each other in sequence.

[0052] See further Figures 3 to 5 As shown, each connector 10A, 10B has two sets of terminals 111A, 111B, 121A, 121B, a first set of terminals 11A, 11B, a set of terminals 13A, 13B, a second set of terminals 12A, 12B, and a knob 14A, 14B.

[0053] The first set of connectors 11A and 11B has one set of terminals 111A and 111B of the connectors 10A and 10B formed on it. The first set of connectors 11A and 11B also has a set of terminals 112A and 112B and an annular groove 113A and 113B. The annular groove 113A and 113B are recessed into the outer wall surface of the terminals 112A and 112B of the first set of connectors 11A and 11B.

[0054] See also Figures 3 to 6As shown, the sockets 13A and 13B are fitted onto the socket ends 112A and 112B of the first set of sockets 11A and 11B, such that the aforementioned annular grooves 113A and 113B are located in the sockets 13A and 13B. The sockets 13A and 13B have an upper end face and a lower end face located at opposite ends, a side face, a socket groove 131A, a slot 132A and 132B, a through hole 133A and 133B, a fixed engagement surface 134A, and a thread ring 135A and 135B. The socket groove 131A is recessed in the lower end face of the sockets 13A and 13B, and the socket ends 112A and 112B of the first set of sockets 11A and 11B protrude from the socket groove 131A. The grooves 132A and 132B extend longitudinally through the upper and lower end faces of the sockets 13A and 13B, and also through the side surfaces of the sockets 13A and 13B. The grooves 132A and 132B divide the first set of sockets 13A and 13B into two pieces that meet on one side, and these two pieces can elastically move closer to each other under pressure. The through holes 133A and 133B extend laterally through the side surfaces of the sockets 13A and 13B, and their opposite ends respectively penetrate the side surfaces of the sockets 13A and 13B. A first central axis extending along the extending direction of the socket groove 131A is defined within the socket groove 131A, and a second central axis extending along the extending direction of the through hole 133A is defined within the through hole 133A. The first central axis and the second central axis are skew to each other. The locking surface 134A is formed on the side surface of the socket 13A, 13B and surrounds one end of the through hole 133A, 133B. The thread loops 135A, 135B are provided on the side surface of the socket 13A, 13B.

[0055] The second set of connectors 12A and 12B has another set of connectors 121A and 121B formed on the connectors 10A and 10B. The second set of connectors 12A and 12B also has a side surface, a set of connecting rods 122A and 122B and a moving engagement surface 123A and 123B. The connecting rods 122A and 122B extend laterally from the side of the second set of connectors 12A and 12B. The connecting rods 122A and 122B extend into and pass through the through holes 133A and 133B of the socket 13A and 13B from the side where the locking surface 134A is provided. They also pass through the annular grooves 113A and 113B of the first set of connectors 11A and 11B along the tangent direction of the annular grooves 113A and 113B, and then protrude out of the through holes 133A and 133B of the socket 13A and 13B. The connecting rods 122A and 122B abut against the bottom of the annular grooves 113A and 113B, and can move along the annular grooves 113A and 113B, and can also rotate within the annular grooves 113A and 113B. The movable engagement surfaces 123A and 123B are formed on the side surfaces of the second set of connectors 12A and 12B and surround the connecting rods 122A and 122B. The movable engagement surfaces 123A and 123B selectively engage with the fixed engagement surfaces 134A of the sockets 13A and 13B to fix the relative angular positions of the second set of connectors 12A and 12B and the sockets 13A and 13B.

[0056] The knobs 14A and 14B are connected to the connecting rods 122A and 122B of the second set of connectors 12A and 12B. The aforementioned sockets 13A and 13B are clamped between the side surfaces of the second set of connectors 12A and 12B and the knobs 14A and 14B. Specifically, the connecting rods 122A and 122B of the second set of connectors 12A and 12B and the knobs 14A and 14B are connected by threads. In a specific embodiment of the present invention, the connecting rods 122A and 122B are provided with external threads 124A and 124B, and the knobs 14A and 14B have a mating groove 141A. The mating groove 141A is provided with internal threads 142A and 142B. The connecting rods 122A and 122B extend into the mating groove 141A. The knobs 14A and 14B and the connecting rods 122A and 122B are engaged with the external threads 124A and 124B through the internal threads 142A and 142B, so that when the knobs 14A and 14B are rotated, they can be driven to move towards or away from the sockets 13A and 13B, thereby selectively tightening the sockets 13A and 13B. More specifically, the internal threads 142A and 142B of the knobs 14A and 14B are formed on a nut 143A and 143B, which are fixed in the mating groove 141A of the knobs 14A and 14B.

[0057] Each extension rod 20A, 20B has two connecting ends. At least one connecting end of each extension rod 20A, 20B is connected to the connecting ends 111A, 111B, 121A, 121B of at least one of the connectors 10A, 10B. The connector 10A can be installed at the end of the extension assembly AA, that is, the connector 10A connects only one connecting end of one of the extension rods 20A, 20B. The connector 10B can also be used to connect two adjacent extension rods 20A, 20B. Specifically, one end of the extension rods 20A and 20B located at the end of the extension assembly AA is connected to one of the connection ends 111A and 111B of the adjacent connector 10A; the two ends of the extension rods 20A and 20B located between the two connectors 10A and 10B are respectively connected to the connection ends 111A and 111B of the first connection seat 11A and 11B of one of the connectors 10A and to the connection ends 121A and 121B of the second connection seat 12A and 12B of the other connector 10B.

[0058] The clamp BB is assembled to one of the sets of terminals 111A, 111B, 121A, and 121B of the extension assembly AA. In a specific embodiment of the present invention, the clamp BB is assembled to the first set of terminals 11A formed on the connector 10A at the end of the extension assembly AA. The clamp BB can be used to further clamp onto components such as tabletops, drum frames, microphone stands, electronic keyboard stands, and music stands to fix the multi-purpose extension shelf of the present invention in a specific position. In a specific embodiment of the present invention, the clamp BB includes two clamping pieces 30, which are pivotally connected to each other. Each clamping piece 30 has an inner side facing the other clamping piece 30, and a buffer pad 31 is provided on the inner side of the clamping piece 30.

[0059] See further Figure 7 and Figure 8As shown, another embodiment of the aforementioned connector 10C is illustrated, wherein: the side surface of the socket 13C has fixed engagement surfaces 134C formed on opposite sides, the two fixed engagement surfaces 134C facing the movable engagement surface 123C of the second set of sockets 12C and the knob 14C respectively; a washer 15C is further provided between the socket 13C and the knob 14C; the connecting rod 122C of the aforementioned second set of sockets 12C sequentially passes through the through hole 133C of the socket 13C and the washer 15C before engaging with the knob 14C, and... The washer 15C is clamped between the knob 14C and the engagement surface 134C facing the knob 14C. The washer 15C can disperse the pressure between the socket 13C and the knob 14C, preventing damage to the surfaces of the socket 13C and the knob 14C. The knob 14C is replaced by a sleeve 144C instead of the aforementioned nuts 143A and 143B. The sleeve 144C is fixed in the engagement groove 141C of the knob 14C, and the internal thread 142C of the knob 14C is formed on the inner ring wall of the sleeve 144C.

[0060] like Figure 2 As shown, a shelf 40 for mounting a tablet electronic device can be connected to the extension assembly AA. The power cord or charging cable of the tablet electronic device can be arranged along the extension assembly AA. The user can thread the power cord or charging cable through the cable loops 135A and 135B of the sockets 13A and 13B, or tie the power cord or charging cable to the cable loops 135A and 135B with a rope to maintain a neat appearance. The aforementioned clamp BB and the shelf 40 are respectively connected to the opposite ends of the extension assembly AA. In a specific embodiment of the present invention, the two ends of the extension assembly AA are respectively provided with the connector 10A. The clamp BB is connected to the connection end 111A formed on the first connection seat 11A of the corresponding connector 10A, and the shelf 40 is connected to the connection end 121A formed on the second connection seat 12A of the corresponding connector 10A.

[0061] See further Figure 3 , Figure 5 and Figure 6As shown, when the knobs 14A and 14B are rotated to move them away from the sockets 13A and 13B, the socket 13A will loosen relative to the socket ends 113A and 113B of the first set of sockets 11A and 11B. Then, the user can rotate the second set of sockets 12A and 12B and the sockets 13A and 13B around the socket ends 113A and 113B of the first set of sockets 11A and 11B, causing the connecting rod 12... When 2A and 122B move along the annular grooves 113A and 113B, they can also cause the second set of connectors 12A and 12B and the extension rods 20A and 20B connected thereto to rotate laterally relative to the sockets 13A and 13B and the first set of connectors 11A and 11B, so that the connecting rods 122A and 122B can rotate within the annular grooves 113A and 113B, thereby adjusting the angular position and extension direction of the extension rods 20A and 20B connected to the second set of connectors 12A and 12B.

[0062] After adjusting the extension rods 20A and 20B to the predetermined angle and extension direction, simply rotating the knobs 14A and 14B to move them closer to the sockets 13A and 13B will force the sockets 13A and 13B to tightly clamp the socket ends 113A and 113B of the first set of sockets 11A and 11B, thereby fixing the relative positions of the first set of sockets 11A and 11B, the sockets 13A and 13B, the second set of sockets 12A and 12B, and the extension rods 20A and 20B.

[0063] The advantage of the multi-purpose extended shelf of the present invention is that by connecting the extension rods 20A and 20B, the clamp BB, and the shelf 40 through the connectors 10A and 10B, the user can adjust the shelf 40, which houses the tablet electronic device, to a height and angle position that allows for comfortable viewing. This allows the user to read the information on the tablet electronic device in a relatively relaxed and safe posture. In addition, the multi-purpose extended shelf of the present invention can also be used to install various auxiliary equipment such as lamps and radio equipment, allowing these auxiliary equipment to be adjusted and placed in the optimal position for radio reception or lighting.
