[0023] During use, through the cooperation of the dust collection module 7 and the blowing module 10, the larger debris on the top surface of the jig body 1 and the placement groove 2 can be effectively cleaned to prevent the larger debris attached to the top surface of the jig body 1 from affecting the PCB board processing, thereby improving the accuracy of PCB board processing. When it is necessary to clean the larger debris on the top surface of the jig body 1 and the placement groove 2, the electric slide rail 4 can be started, and the electric slide rail 4 will drive the installation frame 6 to move on the top surface of the jig body 1. At this time, the blowing module 10 will blow up the larger debris with an angle and stubbornness, so that the dust collection module 7 will suck the larger debris into the collection box 12 through the discharge hose 8 for collection. At the same time, the electric slide rail 4 can drive the installation frame 6 to move horizontally on the top surface of the jig body 1, so that the installation frame 6 can drive the dust collection module 7 and the blowing module 10 to stably clean the top surface of the jig body 1.

[0024] like Figure 1-Figure 4As shown, the bottom surface of the mounting frame 6 is rotatably connected to two rollers 13, and the top surface of the fixture body 1 is provided with two slide grooves 14.
