description The utility model discloses a drilling and tapping device capable of guaranteeing coaxiality. The drilling and tapping device comprises a clamping device, a spring, a sleeve, a connecting rod and a check block. The clamping device penetrates through the stop block; the stop block is fixed on the table top; a drilling drill bit or a tapping drill bit is detachably mounted at the lower end of the clamping device; the spring is arranged on the clamping device in a sleeving manner; wherein the sleeve is sleeved on the clamping device, one end of the connecting rod is connected to the upper end ofthe clamping device, and the other end of the connecting rod is supported on a supporting point; the device is further connected with a control device for controlling the drilling drill bit or the tapping drill bit to rotate at a high speed; and the sleeve and the clamping device are coaxial and are in sliding friction with each other. The drilling and tapping device can guarantee that drilling and tapping meet the requir
