[0024] The central axes of the connecting cylinder I, the connecting cylinder II, the connecting cylinder III, and the connecting cylinder IV coincide with the central axis of the central axis assembly.

[0025] A top end shaft sleeve is provided at the top of the connecting cylinder I; a spring is provided between the top end shaft sleeve and the central locking shaft. The spring shaft is located in the connecting cylinder I and is at the top of the central locking shaft; the spring between the top end shaft sleeve and the central locking shaft is sleeved on the spring shaft.

[0026] A set screw I penetrates through the connecting cylinder I from the side and is connected to the top end shaft sleeve (4).

[0027] The anti-rotation plugging structure includes an anti-rotation plugging block and an anti-rotation plugging groove; the anti-rotation plugging block is located at the bottom of the adjusting seat and is integrally designed with the adjusting seat; the anti-rotation plugging groove is provided on the angle adjusting block; the anti-rotation plugging block is located in the anti-rotation plugging groove.

[0028] The bottom shaft penetrates through the connecting cylinder IV and the connecting cylinder III; the set screw II penetrates through the side wall of the connecting cylinder IV and is connected to the bottom shaft inside it.

[0029] It further includes a spring shaft; the spring shaft is located in the connecting cylinder I and is at the top of the central locking shaft; the spring between the top end shaft sleeve and the central locking shaft is sleeved on the spring shaft.

[0030] Refer to Figures 1 to 3, this embodiment includes a hinge fixing structure A, a hinge fixing structure B, a central locking shaft, a top shaft sleeve, a spring, an adjusting seat, an angle adjusting block, a bottom shaft, a set screw, etc.;

[0031] The hinge fixing structure is an installation structure on both sides of the hinge. The fixing structure A is installed on the platform by screws. The hinge fixing structure B is used to install devices such as antennas. Angle markings are engraved circumferentially at its shaft installation position to facilitate setting the locking angle.

[0032] The central locking shaft is located at its central installation position and has multiple functions. One is to achieve relative rest with the hinge fixing structure A through the plane on the shaft surface. The second is that a round hole is opened at its top, and quick unlocking is achieved through a pull ring. The third is that during the locking process, the bottom boss slides into the angle adjusting block to achieve locking.

[0033] The working principle of the spring and the adjusting seat is that the adjusting seat compresses the spring to create space for the angle adjusting block to change the locking angle. Usually, the spring presses the adjusting block and the angle adjusting block.

[0034] The hinge fixing structure B is used to install devices, and angle groove sequences are installed or machined inside it for realizing the locking fit of the locking pins.

[0035] The angle adjusting block cooperates with the hinge fixing structure B, and different angle lockings are achieved by rotating the angle adjusting block to change the position of the notch.

[0036] Inner columns are provided in both insertion arm boxes, and a radio frequency line and a power line are respectively wound around the two inner columns.

[0037] First, insert the spring 5 from the middle of the hinge fixing structure A into its upper part, then insert the angle adjusting block 7 from the middle of the hinge fixing structure B into its lower part. Subsequently, install the adjusting seat 6 into the middle of the chain fixing structure B. Then align the axes of the hinge fixing structure A and the hinge fixing structure B. Then insert the central locking shaft from the upper part of the hinge fixing structure A. Then pass the spring 5 through the upper part of the central locking shaft. Then pass the top shaft sleeve through the upper part of the central locking shaft and compress the spring 5. Subsequently, tighten with the set screw 9 from the side of the hinge fixing structure A. Pass the bottom shaft through the lower part of the hinge locking structure and tighten it with the set screw 9. Thus, the hinge structure assembly is completed. The adjustment process of the locking structure is as follows: First, squeeze the spring upward with the adjusting seat 6, lift the angle adjusting block 7 and rotate it so that its arrow aligns with the required angle on the hinge fixing structure B, and then drop it to complete the setting of the required angle. The working process is that when the hinge fixing structure 2 is rotated to the required scale, the central locking shaft automatically completes the locking. The unlocking process is to pull up the central locking shaft 3 to complete the unlocking, and rotate the device to the initial position to complete the storage.

[0038] Obviously, those skilled in the art should understand that the various modules or steps of the present application described above can be implemented by a general-purpose computing device. They can be concentrated on a single computing device or distributed over a network composed of multiple computing devices. Optionally, they can be implemented with executable program code, so that they can be stored in a computing device with a storage device for execution, or they can be separately fabricated into individual integrated circuit modules, or multiple modules or steps among them can be fabricated into a single integrated circuit module for implementation. In this way, the present application is not limited to any specific combination of hardware and software.
