[0025] like Figure 1-Figure 5 As shown, a universal tool for board rework and fixing includes: two first fixing bars 1 arranged opposite to each other, and a preset number of second fixing bars 2 erected between the two first fixing bars 1;

[0026] Each first fixing bar 1 is provided with a first through groove 3 along the length direction of the fixing bar, and each second fixing bar 2 is provided with a second through groove 4 along the length direction of the fixing bar. A first stud 5 is provided between the corresponding second through groove 4 and the first through groove 3 to realize the detachable connection between the second fixing bar 2 and the first fixing bar 1. A second stud 6 is detachably installed in each second through groove 4, and each second stud 6 cooperates with a through hole 7 on the board 8 to realize the support and fixation of the board 8.

[0027] It should be noted that Figure 1 For example, the following orientation is only for the convenience of description and is not specifically limited. The two first fixing bars 1 are parallel to each other and symmetrically arranged, respectively located on the upper and lower sides, and the second fixing bars 2 are parallel to each other and are arranged between the two first fixing bars 1 (the second fixing bars 2 are perpendicular to the first fixing bars 1). The number of the second fixing bars 2 is set according to actual needs and is not limited. The more the number of the second fixing bars 2, the further reinforcement of the board 8 can be achieved, and the higher the flatness of the board 8 (such as Figure 5As shown, it is a style in which four second fixing bars 2 are installed); the first through slot 3 is along the left-right direction, the second through slot 4 is along the up-down direction, the second fixing bar 2 is fixed to the first fixing bar 1 by the first stud 5, and the second fixing bar 2 is fixed at each contact point with the first fixing bar 1 by the first stud 5, the second stud 6 is detachably installed in the second through slot 4, the number of the second stud 6 is not limited, and can be set according to actual needs, each second stud 6 cooperates with the through hole 7 on the board 8 to achieve support and fixation of the board 8, at this time, the steel mesh of the card rework workbench is located at the bottom of the tooling to achieve preheating of the board 8, and the heating fan is located above the board 8 to achieve local heating and welding of the board 8. The contact position between the first fixing bar 1 and the second fixing bar 2 is adjusted according to the size of the board 8, and then fixed by the first stud 5, which has strong versatility.

[0028] In one embodiment, each stud comprises a first column 9 and a second column 10 connected to each other, a screw hole 11 is formed at one end of the first column 9 away from the second column 10, and an outer wall of the second column 10 is provided with an external thread.

[0029] It should be noted that each stud includes a first column 9 and a second column 10 that are fixedly connected, the second column 10 is located above the first column 9, and the screw hole 11 is located at the bottom of the first column 9; the first column 9 on the first stud 5 is inserted between the corresponding first through groove 3 and the second through groove 4, and the first column 9 on the second stud 6 is inserted into the corresponding second through groove 4.

[0030] In one embodiment, each stud also includes a screw 12. After the first column 9 on each stud is inserted into the corresponding through slot, the positioning of each stud is achieved by cooperating between the screw 12 and the screw hole 11 on the corresponding first column 9, and the first column 9 is slidably connected to each through slot.

[0031] It should be noted that the screw hole 11 at the bottom of each first column 9 is threadedly connected to the screw 12 to fix each stud (the screw 12 on the first stud 5 passes through the first through slot 3 to the screw hole 11, and the screw 12 is tightened to fix it; the screw 12 on the second stud 6 passes through the second through slot 4 to the screw hole 11, and the screw 12 is tightened to fix it); before tightening the screw 12, the first stud 5 can slide alone in the first through slot 3 or the second through slot 4, and the position between the first through slot 3 and the second through slot 4 (that is, the position between the first fixing bar 1 and the second fixing bar 2) is adjusted according to the size of the board 8, and the second stud 6 can slide in the second through slot 4, and the position of each second stud 6 is adjusted according to the specific position of the through hole 7 on the board 8.
