[0024] In this embodiment, the supporting mechanism 2 includes a mounting frame 13 which is mounted on the inner wall of the supporting ring 10 and is centrally symmetrical along the axis of the supporting ring 10. A mounting groove 2 14 is provided in the mounting frame 13. A rotating rod 15 is rotatably connected to the mounting frame 13 at a position in the middle and close to one side. One end of the rotating rod 15 is rotatably connected to the side wall of the mounting groove 2 14. A knob 16 is installed on the upper end of the rotating rod 15. A gear 17 is installed on the rotating rod 15 located in the mounting groove 2 14. The gear 17 is meshed and connected with a rack 18. A through groove 19 connecting the mounting groove 2 14 is provided on one side of the mounting frame 13. A guide groove 20 is provided on the upper end of the side of the mounting frame 13 away from the through groove 19. The rack 18 is slidably connected to the mounting groove 2 14 located on the side of the through groove 19. A supporting plate 21 sliding in the through groove 19 is installed on the rack 18. A lower end of one side of the supporting plate 21 is slidably connected to the guide groove 20. The support plate 21 is located at the guide groove 20 and is provided with a protrusion that slides in the guide groove 20, and the lower bottom side of the protrusion abuts against the inner wall of the guide groove 20. At the same time, the support plate 21 is located at the through groove 19 and is provided with a connecting block connected to the rack 18, and the connecting block is slidably connected in the through groove 19.

[0025] In this embodiment, a support frame 22 is installed near the middle of the support plate 21, a bolt column 23 is rotatably connected to the upper end of the support frame 22 near the middle, a clamping plate 24 is installed at the lower end of the bolt column 23, a guide rod 25 is installed at the upper end of the clamping plate 24 symmetrical to the position of the bolt column 23, the guide rod 25 is slidably connected to the upper end of the support frame 22, and a knob 26 is installed at the upper end of the bolt column 23.

The bolt column 23 is threadedly matched with the support frame 22, and one end of the bolt column 23 is rotatably connected to the clamping plate 24.

[0026] In this embodiment, the locking mechanism 3 includes a support frame 27 installed on the upper side of the rotating ring 7, a locking rod 28 is slidably connected to the upper end of the support frame 27, a shift block 29 is installed at one end of the locking rod 28, a spring 30 is sleeved on one side of the shift block 29, and the two ends of the spring 30 are respectively connected to the side of the support frame 27 and the shift block 29, and a locking frame 31 is installed on the upper and lower end surfaces of the supporting ring 10 close to the support frame 27, and a plug hole 32 is provided on the locking frame 31, and the locking rod 28 is inserted into the plug hole 32. When the supporting ring 10 rotates 180°, the locking rod 28 is inserted into the plug hole 32, thereby limiting the supporting ring 10 and ensuring that the supporting ring 10 is in a horizontal position.

[0027] In this embodiment, a switch 33 for controlling the conduction of the electromagnet 6 is installed on one side of the base 1. The electromagnet 6 is electrically connected to the on-site power supply, and the switch 33 drives the electromagnet 6 to be turned on and off, thereby controlling the electromagnet 6 to generate or eliminate magnetic force.

[0028] In this embodiment, the two ends of the main board 12 are clamped by the clamping plate 24 on the opposite side and the supporting plate 21. The clamping plate 2 is rotated by the bolt column 23 and moved upward or downward by the guide rod 25.

[0029] The working principle of the utility model is as follows: manually rotate the knobs 26 on both sides and drive the bolt column 23 to move upward, so that the clamping plate 24 moves upward under the action of the guide rod 25, then manually rotate the knob 16 on one side and rotate the rotating rod 15 to drive the gear 17 to rotate, the gear 17 drives the rack 18 to move along the installation groove 14, and the support plate 21 on one side moves under the guidance of the through groove 19 and the guide groove 20, and the two support plates 21 are separated, and then one end of the main board 12 is overlapped on the support plate 21 on the fixed side (if the main board 12 is long, rotate the knob 16 on the fixed side to rotate the rotating rod 15 to rotate the rotating rod 15 to rotate the gear 17, and the gear 17 drives the rack 18 to move along the installation groove 14. The rod 15 drives the gear 17 to rotate and adjusts the distance between the two supporting plates 21 so that the main board 12 can be supported on the two supporting plates 21) and then reverses the knob 16 on the movable side to drive the gear 17 to reverse, so that the rack 18 moves in the opposite direction, thereby making the supporting plate 21 on the movable side move toward the supporting plate 21 on the fixed side, and making the supporting plate 21 on the movable side abut against the other side of the main board 12, and then manually rotates the knobs 26 on both sides and drives the bolt column 23 to move downward, so that the clamping plate 24 moves downward under the action of the guide rod 25, so that the clamping plate 24 cooperates with the supporting plate 21 to clamp the main board 12.

[0030] When the main board 12 is reversed 180°, the locking rod 28 is manually pulled outward through the shift block 29, so that the locking rod 28 is pulled out of the socket 32 ​​and the spring 30 is stretched. Then the supporting ring 10 is rotated 180° around the supporting groove 9 through the supporting column 11, and the locking frame 31 originally located on the lower side of the supporting ring 10 is reversed 180° and located on the upper side of the supporting ring 10. Then the shift block 29 is released, and the locking rod 28 is reset under the action of the elastic force of the spring 30, and the locking rod 28 is inserted into the socket 32 ​​to limit the supporting ring 10 and prevent the supporting ring 10 from rotating.

[0031] When adjusting the horizontal angle of the main board 12, the power supply of the electromagnet 6 is turned off through the switch 32 to demagnetize the electromagnet 6, and then the rotating ring 7 is manually rotated, and the rotating ring 7 rotates along the groove 4. When it is rotated to a suitable position, the power supply of the electromagnet 6 is turned on through the switch 32, so that the electromagnet 6 generates magnetism, and the magnetism generated by the electromagnet 6 adsorbs the iron ring 8 to limit the rotation of the rotating ring 7.

[0032] The utility model clamps the two sides of the main board 12 by the clamping plate 24 and the supporting plate 21 of the supporting mechanism 2, and limits the rotation of the supporting ring 10 by the locking mechanism 3, so as to ensure that the main board 12 is in a horizontal position, and the supporting ring 10 rotates along the groove 4 of the base 1 through the rotating ring 7, so as to facilitate the adjustment of the angle of the main board 12. At the same time, the switch 33 starts the electromagnet 6 to generate magnetic force, and attracts the iron ring 8 installed on the lower side of the rotating ring 7 through the magnetic force, so as to ensure that when the main board 12 is repaired, the rotating ring 7 is prevented from rotating, and the entire device is prevented from rotating by rotating the supporting ring 10, so as to facilitate operation. At the same time, the base 1 adopts a hollow design, and the main board 12 is suspended. When the main board 12 is heated by using an air gun, heat is prevented from being transferred from the bottom side to the table top of the workbench, resulting in insufficient temperature at the heated end of the main board 12, making it inconvenient to disassemble electronic components.

[0033] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
