A workbench 15 is fixedly connected to the bottom of the L-shaped plate 1, and a pair of slide grooves 16 are opened on the top of the workbench 15. A clamping plate 17 is movably connected inside the two slide grooves 16, so that the clamping plate 17 can slide inside the slide grooves 16. An electric telescopic rod 18 is fixedly connected to one side of the workbench 15. A connecting plate 24 fixedly connected to the electric telescopic rod 18 is penetrated on one side of the workbench 15. The connecting plate 24 and a screw rod 19 movably connected to the connecting plate 24 are driven to move by the electric telescopic rod 18. Screw rods 19 movably connected to the connecting plate 24 are penetrated on both sides of the clamping plate 17. The threads on both sides of the screw rod 19 rotate in opposite directions, so that the clamping plate 17 moves inward or outward at the same time. A rotating handle 20 is fixedly connected to one side of the screw rod 19. The screw rod 19 fixedly connected to it is driven to rotate by rotating the rotating handle 20. Four supporting legs 23 are fixedly connected to the four corners of the bottom of the workbench 15, and the device as a whole can be supported by the supporting legs 23.

[0023] When it is necessary to process and tap the mechanical parts, the screw rod 19 fixedly connected to it is rotated by rotating the rotating handle 20, and the rotation of the screw rod 19 drives the clamping plate 17 threadedly connected to it to move inward, and the electric telescopic rod 18 drives the connecting plate 24 fixedly connected to it to move, and the movement of the connecting plate 24 drives the screw rod 19 movably connected to it to move, and the movement of the screw rod 19 drives the clamping plate 17 and the rotating handle 20 to move;

[0024] As a further implementation of this embodiment, Figure 1-Figure 5 As shown, a cylinder 2 is fixedly connected to the top of the L-shaped plate 1, a fixed frame 3 fixedly connected to the cylinder 2 is penetrated on the top of the L-shaped plate 1, and the fixed frame 3 is driven to move up and down by the cylinder 2, and fixed plates 4 are fixedly connected to the two sides of the fixed frame 3, and guide columns 5 movably connected to the tops of the two fixed plates 4 are penetrated, and a protective frame 6 is fixedly connected to the bottoms of the two guide columns 5, and the guide columns 5 and the limit plate 7 are driven to move by squeezing the protective frame 6, and the tops of the two guide columns 5 are fixedly connected to the limit plate 7, and the protective frame 6 can be limited and moved by the limit plate 7, and the outer sides of the two guide columns 5 are sleeved with a spring 8 located between the fixed plate 4 and the protective frame 6, and the spring 8 is compressed by moving the protective frame 6, and the interior of the fixed frame 3 is fixedly connected to a driving motor 12, and a connecting ring 13 fixedly connected to the rotating end of the driving motor 12 is penetrated on the bottom of the fixed frame 3, and a tap 14 is fixedly connected to the bottom of the connecting ring 13, and the tap 14 is driven to rotate by the driving motor 12;

[0025] When it is necessary to process and tap a mechanical part, the driving motor 12 drives the tap 14 fixedly connected thereto to rotate, and the cylinder 2 drives the fixed frame 3 fixedly connected thereto to move, and the movement of the fixed frame 3 drives the guide column 5 movably connected thereto and the protective frame 6 fixedly connected to the guide column 5 to move, so that the protective frame 6 contacts the surface of the mechanical part, and the cylinder 2 moves downward to make the tap 14 tap the mechanical part, and the protective frame 6 moves due to being squeezed, and the movement of the protective frame 6 drives the guide column 5 to move, so that the spring 8 is compressed, to ensure that when the tap 14 moves downward, the protective frame 6 is always in contact with the surface of the mechanical part;

[0026] As a further implementation of this embodiment, Figure 1-Figure 5 As shown, movable grooves 9 are provided on both sides of the fixed frame 3 and the fixed plate 4, and a pair of movable blocks 10 are movably connected inside the two movable grooves 9. The movable blocks 10 are limitedly moved through the movable grooves 9. The internal threads of the two movable blocks 10 are connected with bolts 11, and the movable blocks 10 can be fixed by the bolts 11.

[0027] When the tap 14 needs to be replaced, the bolt 11 is turned to stop fixing the movable block 10, and the movable block 10 is moved away from the fixed plate 4 so that the movable block 10 no longer supports the fixed plate 4. The fixed plate 4 is removed and the tap 14 is replaced. When the tap 14 is replaced, the fixed plate 4 is placed back to its original position, and the movable block 10 is moved between the fixed frame 3 and the fixed plate 4.

[0028] Specific working principle:

[0029] When it is necessary to process and tap a mechanical part, the mechanical part to be tapped is placed on the workbench 15, and the screw rod 19 is rotated by turning the rotating handle 20, and the rotation of the screw rod 19 drives the clamping plate 17 to move inward, and the mechanical part is tightened and fixed by the clamping plate 17, and the tap 14 is driven to rotate by starting the driving motor 12, and the fixed frame 3 driven by the starting cylinder 2 is moved, and the movement of the fixed frame 3 drives the guide column 5 and the protective frame 6 fixedly connected to the guide column 5 to move, so that the protective frame 6 contacts the surface of the mechanical part, and the tap 14 is driven to rotate by the cylinder 2. 4 pairs of mechanical parts are tapped, and the connecting plate 24 fixedly connected thereto is driven to move by the electric telescopic rod 18. The movement of the connecting plate 24 drives the screw rod 19, the clamping plate 17 and the rotating handle 20 to move. The mechanical parts are driven to move by the clamping plate 17, so as to perform tapping processing on other positions of the mechanical parts. When the tap 14 needs to be replaced, the bolt 11 is rotated to stop the fixation of the movable block 10 by the bolt 11, and the movable block 10 is moved away from the fixed plate 4 so that the movable block 10 no longer supports the fixed plate 4, and the fixed plate 4 is removed, and the tap 14 is replaced at this time.
