[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0042] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0043] Reference Figure 1-3A wireless communication terminal with an external antenna includes a body 1, two mounting feet 11 are symmetrically arranged on the body 1, and the two mounting feet 11 are respectively provided with threaded holes, and the wireless communication terminal is detachably installed by the cooperation of bolts, a control panel 12 and a display panel 13 are respectively arranged on both sides of the body 1, and the control panel 12 and the display panel 13 are electrically connected to the internal components of the terminal, and a storage groove 14 and a storage groove 15 are respectively opened on the upper surface of the body 1, and an arc groove 16 is opened on the upper surface of the body 1, and the arc groove 16 is arranged at the end of the storage groove 15 away from the antenna 4, and two guard plates 17 are arranged on the upper surface of the body 1, and the two guard plates 17 is arranged on both sides of the storage slot 15, and the length of the two guard plates 17 is equal to the length of the storage slot 15. Furthermore, when the antenna 4 is stored, a part of the antenna 4 is located in the storage slot 15, and the top of the antenna 4 is in the corresponding arc groove 16, which cooperates with the guard plates 17 arranged on both sides. At the same time, the support plate 5 installed on one side of the antenna 4 contacts with the guard plate 17, thereby providing a more comprehensive protection for the antenna 4, avoiding damage to the antenna 4 caused by squeezing or collision during the carrying or storage of the wireless communication terminal. When the antenna 4 needs to be used again, the top of the antenna 4 can be lifted more conveniently through the opened arc groove 16.

[0044] Reference Figure 4 and Figure 5 A countersunk hole is opened on the upper surface of the body 1, and an assembly seat 2 is fixedly installed in the countersunk hole, and an internal thread is set on the assembly seat 2. A mounting rod 21 is threadedly connected to the assembly seat 2. The mounting rod 21 is screwed into the assembly seat 2 until the bottom of the mounting rod 21 contacts the interface inside the terminal to ensure that the antenna 4 can communicate stably. The antenna 4 is installed on the upper end of the mounting rod 21 through an adjustment mechanism 3. The adjustment mechanism 3 includes a lower sleeve 32 and an upper sleeve 33. A sphere 31 is embedded between the lower sleeve 32 and the upper sleeve 33. The lower sleeve 32 is fixedly connected to the top of the mounting rod 21, and the upper sleeve 33 is fixedly connected to the bottom of the antenna 4.

[0045] The two ends of the sphere 31 are respectively arranged as a flat portion 311 and an arc portion 312. The flat portion 311 is fixedly connected to the top of the mounting rod 21. The arc portion 312 extends into the upper sleeve 33. The sphere 31 is symmetrically provided with cutting portions 313. It should be noted that, through the arranged sphere 31, the upper sleeve 33 and the lower sleeve 32 can be rotated. When relative movement occurs between the upper sleeve 33 and the sphere 31, it is specifically manifested as the rotation of the antenna 4 and the support plate 5 with the sphere 31 as the axis. At the same time, due to the limiting effect of the cutting portions 313 on both sides of the sphere 31, the antenna 4 can only swing in the direction of the storage slot 15, thereby ensuring that the antenna 4 accurately enters the storage slot 15.

[0046] A support plate 5 is installed on one side of the antenna 4, and the bottom of the support plate 5 is connected to the antenna 4 through an L-shaped plate. The support plate 5 and the antenna 4 remain parallel to ensure that the antenna 4 is firmly installed to avoid shaking or shifting during use. Two limit rods 51 are arranged on the side wall of the support plate 5. It should be noted that the two limit rods 51 are made of rubber material, have a certain curvature and can be deformed. When the antenna 4 is received in the storage slot 15, the support plate 5 is kept horizontally above the antenna 4, and the two limit rods 51 on the support plate 5 are erected upwards. At this time, the electronic device can be placed in the storage slot 15. The amplifier 92 is moved to the limit rod 51, so that the two limit rods 51 are inserted into the electronic amplifier 92, thereby fixing the electronic amplifier 92 to prevent the electronic amplifier 92 from shaking and colliding with other objects after the storage is completed. Furthermore, through the fixing effect of the two limit rods 51, the electronic amplifier 92 is located above one end of the antenna 4 interface. When located in a small space, the antenna 4 cannot be opened and remain vertical, and the signal strength received by the wireless communication terminal can be directly improved through the gain effect of the electronic amplifier 92, thereby maintaining the normal use of the wireless communication terminal.

[0047] Reference Figure 6 A transmission mechanism 6 is provided in the storage groove 14, and the transmission mechanism 6 includes a threaded rod 61, and a nut 64 is threadedly connected on the threaded rod 61. One end of the threaded rod 61 is rotatably connected to the inner wall of the storage groove 14 through a bearing seat, and the other end of the threaded rod 61 is fixedly connected to an extension rod 62, and the extension rod 62 is connected to the body 1 through and through, and the end of the extension rod 62 away from the threaded rod 61 is fixedly connected to a knob 63, and a slider 65 is fixedly connected to the nut 64. The upper end of the slider 65 is connected to a connecting plate 7 through a rotating seat 66. The width of the connecting plate 7 is equal to the width of the storage groove 14. When the electronic amplifier 92 is retracted after use, the connecting plate 7 is connected to the electronic amplifier 92. The plate 7 is fitted with the upper opening of the storage groove 14 to close it, which can protect the components inside the storage groove 14. The bottom of the slider 65 is embedded in the storage groove 14, and the top of the slider 65 extends to the outside of the storage groove 14. Furthermore, under the support of the bearing seat and the extension rod 62, turning the knob 63 can drive the threaded rod 61 to rotate synchronously. Since the side wall of the slider 65 is against the inner wall of the storage groove 14, it can limit the nut 64, and finally the nut 64 moves with the slider 65 along the direction set by the threaded rod 61, driving one end of the connecting plate 7 to move, thereby adjusting the angle and position of the connecting plate 7.

[0048] Reference Figure 7, a support seat 81 is installed on one side of the movable block 72 through a connecting rod 8, the connecting rod 8 passes through the support seat 81, and the connecting rod 8 is fixedly connected to the support seat 81, the top of the connecting rod 8 is coaxially fixedly connected to the combining pin 71, a through slot 82 is provided on the support seat 81, the support seat 81 is slidably sleeved on the support plate 5, and the end of the connecting plate 7 away from the rotating seat 66 is connected to the movable block 72 through the combining pin 71, the combining pin 71 is arranged between the connecting plate 7 and the movable block 72, and the connecting plate 7 is rotatably connected to the combining pin 71, and the movable block 72 is fixedly connected to the combining pin 71. It should be noted that when When the nut 64 drives one end of the connecting plate 7 to move, the connecting plate 7 swings with the rotating seat 66 as the axis, and the other end of the connecting plate 7 rotates with the combining pin 71. Since the inner wall of the through groove 82 abuts against the side wall of the support plate 5, the angle and position of the connecting plate 7 can be fixed by relying on the friction between them and the position of the nut 64. Furthermore, when the wireless communication terminal is in use, the support seat 81 and the support plate 5 contact each other, and finally the electrostatic charge free on the antenna 4 can be guided to the outer shell of the body 1 to avoid the generation of an electrostatic field that affects the signal reception quality of the antenna 4.

[0049] An electronic amplifier 92 is installed on the movable block 72, and the electronic amplifier 92 is sleeved on the antenna 4. A contact ball 91 is fixedly connected to the electronic amplifier 92, and a plug rod 9 is fixedly connected to the lower end of the contact ball 91. A slot 73 is provided on the movable block 72, and the size of the slot 73 corresponds to the size of the plug rod 9. By inserting the plug rod 9 into the slot 73 provided on the movable block 72 and cooperating with the limiting function of the contact ball 91, the installation of the electronic amplifier 92 can be quickly completed.

[0050] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
