[0028] The movable fixture 6 is slidably connected to the inner wall of the movable rod 3 , and the translation fixture 7 is slidably connected to the outer wall of the outer frame 101 .
[0029] The technical solution provided by this embodiment is: first, several positioning pins are pulled out, and then the PCB board is placed on the upper side of the device, and the moving rod 3 is moved so that it is roughly the same size as the PCB board, and then the PCB board is placed on the platform protruding from the moving fixture 6 and the translation fixture 7, and then the positioning pins are inserted into the inside of the platform through the through holes opened on the PCB board. After the PCB board is roughly fixed, first rotate the first positioning screw 4. The rotation of the first positioning screw 4 causes the positioning block 5 to move upward so that it is clamped and fixed on the surface of the outer frame 101, fixing the position of the moving rod 3. Then, rotate the second top positioning screw 604. The rotation of the second positioning screw 604 causes the upper positioning block 601 and the first moving block 602 to move relative to each other, and clamp the moving rod 3 to fix the position of the moving fixture 6. Finally, rotate the third positioning screw 703 to fix the position of the translation fixture 7.
[0030] Furthermore, the end of the first positioning screw 4 is threadedly connected to the end of the positioning block 5 , and the first positioning screw 4 passes through the through slot 102 .
[0031] Specifically, the provision of the through slot 102 enables the moving rod 3 to be fixed no matter where it is located on the outer frame 101 .
[0032] Furthermore, the movable clamp 6 includes a first movable block 602, an upper positioning block 601 is arranged above the first movable block 602, the interior of the upper positioning block 601 is rotatably connected to a second positioning screw 603, the end of the second positioning screw 603 is threadedly connected to the interior of the first movable block 602, and a first positioning pin 604 is inserted into the interior of the first movable block 602.
[0033] Specifically, the arrangement of the upper positioning block 601 and the first moving block 602 enables the movable fixture 6 to be fixed quickly and more precisely.
[0034] Furthermore, the translation clamp 7 includes a fixed body 701, the outer wall of the fixed body 701 is slidingly connected to the second moving block 702, the interior of the fixed body 701 is rotatably connected to the third positioning screw 703, the end of the third positioning screw 703 is threadedly connected to the inner wall of the second moving block 702, the fixed body 701 and the second moving block 702 jointly clamp the outer frame 101, the third positioning screw 703 passes through the through slot 102, and the interior of the fixed body 701 is inserted with a second positioning pin 704.
[0035] Specifically, the arrangement of the translation fixture 7 enables the device to accurately fix different PCB boards.
[0036] Furthermore, the two moving rods 3 are symmetrically arranged.
[0037] Specifically, the two moving rods 3 are symmetrically arranged so that the moving rods 3 divide the outer frame 101 into two areas, so that the device can fix two or more PCB boards at the same time.
[0038] Furthermore, four fixing rings 2 are fixedly connected to the outer wall of the fixing frame 1 .
[0039] Specifically, the setting of the fixing ring 2 provides a specific positioning point for fixing the fixing frame 1 as a whole.
[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
