The spindle base 20 is connected to the machine base 10 in a manner of being capable of moving up and down relative to the machine base 10; a displacement adjusting device 15 may be disposed between the spindle base 20 and the machine base 10, where the displacement adjusting device 15 includes a rack 151 and a gear 152 meshed with each other and respectively disposed on the spindle base 20 and the machine base 10, and an operating member 153 connected to the gear 152, where the rack 151 is disposed on the spindle base 20, the gear 152 is disposed on the machine base 10, and the operating member 153 may be in the form of a handle or an operating disc, and a user may rotate the operating member 153 to drive the spindle base 20 to move up and down relative to the machine base 10; further, a control button 70 for controlling the spindle of the tapping machine to perform tapping machining may be mounted on the control member 153, and the control button 70 is electrically connected to a controller, when the user rotates the control member 153 to adjust the spindle seat 20 to move down to make the tool contact with the workpiece, the control button 70 on the control member 153 may be directly pressed to control the tapping machine to perform tapping machining, and the workpiece is reversely withdrawn.

The pulley block 30 comprises a disc 31 and a connecting cable 33, wherein the disc 31 is rotatably disposed on the base 10 relative to the base 10 and above the spindle base 20, the connecting cable 33 is wound around the disc 31 and has a first connecting section and a second connecting section respectively extending downward from opposite radial sides of the disc 31, and the first connecting section is connected with the spindle base 20. The two ends of the extension spring member 40 are respectively connected to the base 10 and the second connecting section of the connecting cable 33.

Preferably, referring to fig. 4 and 5, the disc 31 is provided with a first channel 312 and a second channel 314, the connecting cable 33 includes a first cable 331 and a second cable 332, one end of the first cable 331 is fixed to the disc 31, and the first cable 331 is wound around the disc 31 along the first channel 312 and extends downward to form the first connecting section connected to the spindle base 20; one end of the second cable 332 is fixed to the disc 31, and is wound around the disc 31 along the second channel 314, and extends downward to form the second connecting section connected to the extension spring member 40; the first cable 331 and the second cable 332 can be steel cables.
