This design is to facilitate the movement of the movable block 4.

[0024] A telescopic spring 5 is fixedly connected to the connection between the movable block 4 and the first outer frame 1, and a connecting rod 6 is slidably connected to the outer wall of the movable block 4 and the side of the telescopic spring 5. The movable block 4 lifts up the printing jig 2, so that it is not easy to touch the solder paste on the printed circuit board.

[0025] Specifically, the outer wall of the first outer frame 1 is symmetrically provided with slots 102 , the inside of the movable block 4 and at the bottom of the slot 102 is provided with a mounting slot 401 , and the outer wall of the connecting rod 6 and the inside of the mounting slot 401 are slidably interlaced and connected.

[0026] It should be noted that the connection rod 6 is designed to facilitate the movement of the movable block 4 so that the printing top block 3 lifts up the movable block 4 and thus lifts up the printing jig 2 .

[0027] Furthermore, a mounting block 7 for connecting the first outer frame 1 and the movable block 4 is disposed inside the slot 102, a supporting block 9 for supporting the connecting rod 6 is disposed inside the mounting groove 401, and the top of the connecting rod 6 and the middle of the mounting block 7 are interlaced and connected.
