The invention discloses a high-efficiency wood cutting device for building furniture, which includes a base, a straightening assembly, a conveying assembly, a cutting assembly and a receiving assembly, wherein a power box is fixed on the top of the base to provide power for the device, and the power Side plate 1 is fixed on one side of the box, and side plate 2 is fixed on the side of the top of the base far away from the power box. A plurality of rollers 1 are rotatably arranged between the side plate 1 and side plate 2. The first roller is slidably provided with a centering assembly, which can prevent the wood from skewing during cutting, resulting in an uneven cutting surface. The conveying assembly is arranged between the first side plate and the second side plate. The cutting assembly is fixed at one end close to the conveying assembly, and the receiving assembly is fixed at one side of the base, which can collect the cut wood and allow wood chips to fall into the bottom of the collecting assembly.

The present application discloses a calibration and detection device for a nitrogen-oxygen sensor, which includes a main engine, on which an exhaust module for discharging exhaust gas and a detection module for receiving a detection signal of a probe and displaying a numerical value of nitrogen oxide content are arranged. The exhaust module is electrically connected with the detection module, and the present application has the effect of being able to detect the inductive performance of the probe.
