[0029] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0030] This utility model provides a handheld terminal with a quick-release structure, including a handheld device 11 and a self-organizing wireless module 12 detachably connected to one end of the handheld device 11. One end of the handheld device 11 is provided with multiple first fixing slots 111. One end of the self-organizing wireless module 12 is provided with multiple fixing protrusions 121 that match the first fixing slots 111 and can extend into the first fixing slots 111, and a quick-release device 13 for fixing the fixing protrusions 121 into the first fixing slots 111. The quick-release device 13 includes a screw 131, a spring 132 connected within the screw 131, and a pull ring 1311 located at the top of the screw 131. When the quick-release device 13 is locked, the screw 131 passes through the fixing protrusions 121 and locks with the handheld device 11. The handheld device 11 can be an electronic product such as a mobile phone or tablet. The self-organizing wireless module 12 is a wireless module that uses wireless technology for wireless data transmission. When the self-organizing wireless module 12 is installed in the handheld device... When using device 11, first, install spring 132 inside screw 131, insert the fixing protrusion 121 of self-organizing wireless module 12 into the first fixing groove 111, and insert screw 131 with spring 132 installed into fixing protrusion 121. Rotate screw 131 to fix screw 131 onto handheld device 11. Since there is a pull ring 1311 on the top of screw 131, the user can pinch pull ring 1311 and rotate to fix screw 131 into the first fixing groove 111, thereby fixing fixing protrusion 121 onto handheld device 11. When it is necessary to disassemble self-organizing wireless module 12, rotate pull ring 1311 to rotate screw 131 out of handheld device 11 to disassemble self-organizing wireless module 12. Self-organizing wireless module 12 can be installed on handheld device 11 or disassembled from handheld device 11, which is convenient for later replacement or maintenance of self-organizing wireless module 12.

[0031] The pull ring 1311 is rotatably connected to the screw 131. The top side of the screw 131 is provided with an arc-shaped groove 1315 for receiving the pull ring 1311. The arc-shaped groove 1315 is used to receive the pull ring 1311. When the screw 131 is not in use, the pull ring 1311 is stored in the arc-shaped groove 1315, which can effectively reduce the volume of the screw 131 and at the same time prevent the pull ring 1311 from protruding and causing damage to the pull ring 1311.

[0032] The end of the screw 131 away from the pull ring 1311 is also provided with a thread 1312. The diameter of the thread 1312 is larger than the diameter of the spring 132. The end of the handheld device 11 connected to the screw 131 is provided with a thread that is threaded to the thread 131. The thread 1312 is used to limit the spring 132 and prevent the spring 132 from separating from the screw 131. The screw 131 is fixed to the handheld device 11 by the thread, thereby fixing the self-organizing wireless module 12 to the handheld device 11, which facilitates the installation and removal of the screw 131.

[0033] Please refer to Figure 2 , Figure 2 This is a perspective view of the quick-release device of the handheld terminal with a quick-release structure according to this utility model. The fixing protrusion 121 is provided with a first placement groove 122 for placing the top of the screw 131, a second placement groove 123 located within the first placement groove 122 for placing the spring 132, and a through hole 124 located within the second placement groove 123 for the screw 131 to pass through. The diameter of the first placement groove 122 is larger than the diameter of the second placement groove 123. The first placement groove 122 is used to place the head of the screw 131, thereby reducing the volume of the screw 131 connected to the self-organizing wireless module 12. The second placement groove 123 is used to place the spring 131. 2. When the screw 131 is connected to the handheld device 11, the screw 131 and the second placement groove 123 compress the spring 132, thereby limiting the spring 132 within the second placement groove 123. On the one hand, when fixing the screw 131, if the thread 1312 of the screw 131 slips and compresses the spring 132, the spring 132 can compress the screw 131 in the opposite direction, thereby observing whether the screw 131 is fixed. On the other hand, when disassembling the screw 131, when the screw 131 is separated from the handheld device 11, the spring 132 compresses the screw 131 in the opposite direction, which can clearly show whether the screw 131 is separated from the handheld device 11.

[0034] The fixing protrusion 121 is provided in three triangular shapes. The triangular arrangement of the fixing protrusion 121 can effectively fix the self-organizing wireless module 12 to the handheld device 11, preventing the self-organizing wireless module 12 from becoming loose on the handheld device 11.

[0035] A through groove 125 communicating with the through hole 124 is also provided on the side of the fixed protrusion 121 away from the first placement groove 122. The width of the through groove 125 is greater than the diameter of the thread 1312, which makes it convenient to install the spring 132 in the screw 131.

[0036] The top of the screw 131 is also provided with a groove 1313 for connecting to a screwdriver. The groove 1313 is used to facilitate the rotation of the screw 131 with a screwdriver. In the event that the pull ring 1311 is broken, the screw 131 can also be disassembled with a screwdriver, making it more convenient to use.

[0037] The side wall of the pull ring 1311 is also provided with a second fixing groove 1314. When the pull ring 1311 is stored, a finger can be inserted into the second fixing groove 1314 to pull the pull ring 1311 in the unfolding direction, so as to unfold the pull ring 1311.

[0038] Working principle:

[0039] When installing the self-organizing wireless module 12, firstly, the spring 132 is fitted into the screw 131, with the spring 132 positioned between the head of the screw 131 and the thread 1312. Since the diameter of both the thread 1312 and the head of the screw 131 is larger than that of the spring 132, the spring 132 is thus limited between the thread 1312 and the head of the screw 131. Then, the screw 131 with the spring 132 installed is installed into the fixing protrusion 121, with the thread 1312 of the screw 131 passing through the through hole 124 of the fixing protrusion 121. The thread 1312 of the screw 131 is positioned within the fixing protrusion 121. On one side of the through groove 125 of the protrusion 121, the fixing protrusion 121 of the self-organizing wireless module 12 is further inserted into the first fixing groove 111. The pull ring 1311 is rotated, causing the screw 131 to rotate. The screw 131 extends into the internal thread of the handheld device 11. Simultaneously, the head of the screw 131 compresses the spring 132, causing the spring 132 to deform within the second placement groove 123. When the head of the screw 131 is located within the first placement groove 122, the rotation of the pull ring 1311 is stopped, and the pull ring 1311 is pressed down from the direction of the arc-shaped groove 1315, thereby... The pull ring 1311 is housed in the arc-shaped groove 1315. Due to the action of the spring 132, if the screw 131 is not fixed in the handheld device 11 or the screw thread 1312 slips with the handheld device 11, the spring 132 will press the head of the screw 131 in the opposite direction, making it easy for the user to know whether the screw 131 is locked in the handheld device 11. Furthermore, when replacing or repairing the self-organizing wireless module 12, a finger can be inserted into the second fixing groove 1314 and pulled in the unfolding direction of the pull ring 1311, so that the pull ring 1311 is in the screw head. The device unfolds and the pull ring 1311 is rotated. The pull ring 13 drives the screw 131 to rotate, causing the screw 131 to separate from the handheld device 11. When the screw 131 separates from the handheld device 11, the spring 132 loses its squeezing force and squeezes the head of the screw 131 in the opposite direction. The user can clearly observe whether the screw 131 has separated from the handheld device 11. With the above structure, the self-organizing network wireless module 12 can be quickly installed on the handheld device 11 or disassembled from the handheld device 11, which is convenient for self-organizing network maintenance or replacement of the self-organizing network wireless module 12 and makes it more convenient to use.

[0040] This preferred embodiment of the handheld terminal with a quick-release structure allows for rapid disassembly of the self-organizing network wireless module when it needs to be removed from the handheld device. The rotating pull ring causes the screw to rotate, and when the screw separates from the handheld device, the spring, having lost its compressive force, reverses and presses the screw. This allows the user to easily observe whether the screw has separated from the handheld device, enabling quick disassembly of the self-organizing network wireless module. This facilitates the repair or replacement of the self-organizing network wireless module and makes it more convenient to use.

[0041] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
