The magnetic plate 2 is slidably connected to the workbench 1 through two fixing blocks 7 fixed thereon, and the two handles 14 are pulled inward to drive the limit blocks 16 fixed thereto to move simultaneously. The overall disassembly and assembly is convenient, which is convenient for later cleaning and maintenance.

The overall idea is as follows:

[0026] The lower surfaces of the two clamping blocks 12 are movably connected with sliders 11, and the two sliders 11 are slidably connected with the clamping slot 10. A group of clamping slots 18 are provided on the rear surface of the connecting plate 17, and the group of clamping slots 18 are movably connected with two limit blocks 19 respectively. The magnetic suction plate 2 is slidably connected to the workbench 1 through the two fixed blocks 7 fixed thereon. The limit blocks 16 fixed thereto are driven to move simultaneously by pulling the two handles 14 inward, and the two springs 15 are compressed. At this time, the two limit blocks 16 are separated from the two fixed blocks 7, and the limit is opened. The magnetic suction plate 2 can be disassembled, and the overall disassembly and assembly are convenient, which is convenient for later cleaning and maintenance.

[0027] The rear surfaces of the two limit blocks 19 are fixedly connected with springs 20, and the two springs 20 are fixedly connected with the two card blocks 12 respectively.

[0028] Working principle:

[0029] The chip board 3 to be brazed is placed between the two pairs of fixing columns 8 for fixing. The two pairs of fixing columns 8 can be firmly adsorbed on the magnetic suction plate 2 through their magnetic bases, providing a stable support point for welding and ensuring that the chip board 3 will not shift during the welding process. The magnetic suction plate 2 is slidably connected to the workbench 1 through the two fixing blocks 7 fixed thereon. The two handles 14 are pulled inward to drive the limit blocks 16 fixed thereto to move at the same time, compressing the two springs 15. At this time, the two limit blocks 16 are separated from the two fixing blocks 7, the limit is opened, and the magnetic suction plate 2 can be disassembled. The overall disassembly and assembly are convenient, which is convenient for later cleaning and maintenance. When the chip board 3 is clamped, the clamp 4 is needed to clamp the chip board 3. The two universal tubes 5 allow free adjustment in different directions, so that the welding point can be easily positioned within the operator's most comfortable line of sight and operating range, reducing adjustment time and improving work efficiency. Pressing the pressing block 21 backward drives the limit block 2 19 fixed thereto to move together, compressing the spring 20.
