[0026] See also Figure 1-5 , the utility model provides a technical solution:

[0027] The guiding mechanism for a PCB board comprises a fixed base plate 1, a slide groove 2 and a guide block 3. The inner side of the upper end of the fixed base plate 1 is provided with a slide groove 2 for limiting the sliding of the guide block 3. The guide block 3 is slidably connected inside the slide groove 2. An adjusting mechanism 4 is installed inside the guide block 3. The adjusting mechanism 4 comprises a threaded rod 41. A hexagonal prism 42 is fixedly connected to one end of the threaded rod 41 close to the center point of the fixed base plate 1. The hexagonal prism 42 is connected to a connecting piece 44. A bearing 45 is installed outside the connecting piece 44. The connecting piece 44 comprises a cylinder 441. Hexagonal grooves 442 for connecting the hexagonal prism 42 are provided inside both ends of the cylinder 441. A telescopic spring 443 is installed inside the hexagonal groove 442.

[0028] As a further implementation of the present scheme, four threaded rods 41 are provided, wherein one end of two adjacent threaded rods 41 is fixedly connected with a button cap 43, the button cap 43 is exposed outside the fixed base plate 1, a threaded hole 7 is provided inside the bottom end of the guide block 3, the threaded rod 41 and the guide block 3 are spirally connected through the threaded hole 7, and the guide block 3 can be driven to move during the rotation of the threaded rod 41 through the provided threaded hole 7, and at the same time, the button cap 43 exposed outside the fixed base plate 1 is convenient for controlling the rotation of the threaded rod 41;

[0029] As a further implementation of the present solution, the end of the threaded rod 41 away from the center of the fixed base plate 1 is a cylindrical smooth surface, and the end of the threaded rod 41 away from the center of the fixed base plate 1 is installed inside the edge of the fixed base plate 1, and the end of the threaded rod 41 away from the center of the fixed base plate 1 is exposed outside the fixed base plate 1, so that the threaded rod 41 can be stably limited and the stability of the threaded rod 41 during movement can be ensured;

[0030] As a further implementation of this solution, two connecting members 44 are provided, and the connecting members 44 are rotatably connected to the inside of the support tray 5 through a bearing 45. The two connecting members 44 are distributed up and down, and the angle formed between the two connecting members 44 is 90°, which can further limit the threaded rod 41;

[0031] As a further implementation of this solution, the hexagonal prism 42 is slidably connected to the cylinder 441 through the hexagonal groove 442, and the hexagonal prism 42 is fixedly connected to the telescopic spring 443, which can ensure the stability of the threaded rod 41 in the process of driving the guide block 3 to move;

[0032] As a further implementation scheme of the present scheme, a support tray 5 is fixedly connected to the middle of the upper end of the fixed base plate 1, a rubber pad 6 is fixedly connected to the upper end of the support tray 5, a mounting hole 8 is opened on the inner side of the edge of the fixed base plate 1, four guide blocks 3 are provided, and the upper end of the guide block 3 is arc-shaped. Through the above arrangement, the convenience of removing the PCB board from the upper end of the fixed base plate 1 and placing it later is further improved.

[0033] Working process: in the process of adjusting the position of the guide block 3 by means of the button cap 43, rotating the button cap 43 can directly drive one of the threaded rods 41 to rotate. In the process of the rotation of the threaded rod 41, the corresponding threaded rod 41 can be driven to rotate by means of the hexagonal prism 42 and the cylinder 441, and then the two correspondingly set guide blocks 3 are driven to move by means of the threaded rods 41 with two corresponding threads set in opposite directions, so as to complete the clamping and fixing of the corresponding two sides of the PCB board. The clamping and fixing of the other corresponding two sides of the PCB board are also realized by the above method. After the fixing is completed, when the PCB board is placed between the guide blocks 3, the guide block 3 will be slightly squeezed. Since the threaded rod 41 is connected to the cylinder 441 by means of the hexagonal prism 42 and the telescopic spring 443, it can move slightly (the threaded rod 41 is in contact with the fixed base plate 1 through the cylindrical smooth surface setting, so that it can rotate and slide at the same time), so as to ensure that the guide block 3 can move in the above process, which has a good buffering effect and further improves the convenience of taking out the PCB board from the upper end of the fixed base plate 1 and placing it later.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
