[0030] The workbench 3 is a continuous structure, and placement slots 4 are provided on both sides of the top of the workbench 3. The placement slots 4 are rectangular in structure. Positioning strips 11 are installed on the bottom ends of both sides of the processing jig 5 by bolts. The positioning strips 11 are rectangular in structure. In this way, the processing jig 5 is placed on the upper end of the workbench 3, and the bottom end of the processing jig 5 is contacted and squeezed with the upper end of the fixed suction cup 12 installed in the installation slot 13. When the processing jig 5 is fixed, the vacuum pump 8 is started to extract the air inside the fixed suction cup 12 through the multi-head connecting pipe 9, and the fixed suction cups are all Negative pressure is generated inside 12, so that the processing jig 5 is fixed by the fixed suction cup 12, increasing the firmness of the processing jig 5 during use. When different processing jigs 5 are replaced as needed, the vacuum pump 8 is directly turned off to make the fixed suction cup 12 lose suction, so that the processing jig 5 never loses its restraint, and the processing jig 5 can be replaced.

The fixing grooves 17 are rectangular in structure, and the fixing electromagnetic blocks 16 are located directly below the positioning strip 11, so that the fixing electromagnetic blocks 16 are installed and fixed by the fixing grooves 17;

[0033] A trigger mechanism 7 is installed on the right side of the top of the fixed bottom frame 1. The trigger mechanism 7 includes a trigger tube 701, a movable plate 702, a mounting spring 703, a movable contact ring 704 and a fixed contact ring 705. The trigger tube 701 is installed on the right side of the top of the fixed bottom frame 1 by bolts. The left end of the trigger tube 701 and the right side of the multi-head connecting tube 9 are installed with a connecting air pipe 10 by bolts.

The movable contact ring 704 is installed on the left side of the movable plate 702 by screwing. The fixed contact ring 705 is installed on the left side of the inner cavity of the trigger tube 701 by bolts. The movable contact ring 704 and the fixed contact ring 705 are electrically connected to the fixed electromagnetic block 16 through a wire. In this way, when the vacuum pump 8 is started, the inside of the trigger tube 701 is connected through the connecting air pipe 10. The air on the left side is sucked away, so that the left side of the trigger tube 701 is in a negative pressure state, and the movable plate 702 moves to the left side. When the movable plate 702 moves to the left side of the trigger tube 701, the movable contact ring 704 and the fixed contact ring 705 are in contact, and the fixed electromagnetic block 16 is activated to generate magnetism and magnetically attract the positioning strip 11, thereby increasing the firmness of the processing jig 5 when it is replaced and installed, and preventing the processing jig 5 from loosening and deviating due to insufficient firmness during processing, thereby affecting the normal processing efficiency. When the movable plate 702 moves to the left side of the trigger tube 701, the installation spring 703 is stretched, so that the stretched installation spring 703 can drive the movable plate 702 to reset later, so that the movable contact ring 704 is separated from the fixed contact ring 705, and the power supply of the fixed electromagnetic block 16 is disconnected, so that the fixed electromagnetic block 16 loses its magnetism.

[0034] The mounting spring 703 is made of spring steel, the outer periphery of the movable plate 702 and the inner periphery of the trigger tube 701 are polished, the middle of both sides of the fixed bottom frame 1 are movably mounted with a placement plate 2, and blocks are equidistantly mounted around the upper end of the placement plate 2. The placement plate 2 is a rectangular structure, and the middle of both sides of the trigger tube 701 are provided with connecting through holes.

The cross-sections of the fixed sleeve plates 14 are inverted U-shaped structures. The fixed sleeve plates 14 are installed with support rods on the side away from the fixed bottom frame 1 and the bottom ends of the placement plates 2 by bolts. In this way, when the placement plates 2 are installed to the middle of the two sides of the fixed bottom frame 1, the fixed sleeve plates 14 are installed to the outside of the fixed embedded plates 15 through the placement plates 2. Then, by using the fixed sleeve plates 14 and the fixed embedded plates 15 in combination, the placement plates 2 can be directly fixed, and it is faster to disassemble and install.

[0036] Working principle: The present invention places the processing jig 5 on the upper end of the workbench 3, and makes the bottom end of the processing jig 5 contact and squeeze with the upper end of the fixed suction cup 12 installed in the installation groove 13. When the processing jig 5 is fixed, the vacuum pump 8 is started to extract the air inside the fixed suction cup 12 through the multi-head connecting pipe 9, and a negative pressure is generated inside the fixed suction cup 12, so that the processing jig 5 is fixed by the fixed suction cup 12, and the firmness of the processing jig 5 during use is increased. When different processing jigs 5 are replaced as needed, the vacuum pump 8 is directly turned off to make the fixed suction cup 12 lose suction, and the processing jig 5 never loses its restraint force, and the processing jig 5 can be replaced. The replacement, installation and fixing are faster, and the operation can be completed without any tools. The unused materials can be processed and replaced with the corresponding processing jig 5, which increases the compatibility during processing and use.

[0037] At the same time, when the vacuum pump 8 is started, the air on the left side of the trigger tube 701 is sucked away through the connecting air pipe 10, so that the left side of the trigger tube 701 is in a negative pressure state, and the movable plate 702 moves to the left side. When the movable plate 702 moves to the left side of the trigger tube 701, the movable contact ring 704 and the fixed contact ring 705 are in contact, and the fixed electromagnetic block 16 is started to generate magnetism and magnetically attract the positioning strip 11, thereby increasing the firmness of the processing jig 5 when it is replaced and installed, and preventing the processing jig 5 from loosening and deviating due to insufficient firmness during processing, thereby affecting the normal processing efficiency. When the movable plate 702 moves to the left side of the trigger tube 701, the installation spring 703 is stretched, so that the movable plate 702 can be reset by the stretched installation spring 703 later, so that the movable contact ring 704 is separated from the fixed contact ring 705, and the power supply of the fixed electromagnetic block 16 is disconnected, so that the fixed electromagnetic block 16 loses its magnetism and the processing jig 5 loses its restraint force.
