The electric chisel comprises an electric drill, a casing, a push rod and chisel head mechanism and a groove cam mechanism. The top of the casing is provided with an oil hole, and a rubber plug is arranged on the oil hole to be used for preventing dust; the two ends of the groove cam mechanism are provided with a first bearing and a second bearing respectively, and a first groove and a second groove are formed below the first bearing and the second bearing respectively and positioned in the inner wall of the casing. The groove cam mechanism is provided with a groove, and the push rod and chisel head mechanism is connected with the groove cam mechanism and performs reciprocating motion up and down in the groove of the groove cam mechanism.

Abstract: This invention provides a small molecule oligonucleotide aptamer binding to T-2 toxin specifically, and the sequence of the ssDNA aptamer is SEQ ID NO: 1. Through the graphene oxide separation-based Systematic Evolution of Ligands by Exponential Enrichment, single-stranded oligonucleotide aptamer with high affinity and specific identification of T-2 toxin was obtained in vitro selection. The aptamer has a broad application prospect, which can be used for separation and enrichment of trace T-2 toxin in the sample. It can also be used as a reporter aptamer for the detection of T-2 toxin in food by means of functional groups labeling and other means.

Abstract: The present invention discloses a 3D diffraction coating process, the operation is simple, due to the principle of newton's rings of single light sources, superimposition of optical wave-wavlet vibration during wave transmission of light and diffraction, refraction, reflection, transmission, transmission increase and reflection increase of the light, slit diffraction generated by a round hole, a rectangular hole and a line in a pattern internally coated in the product is conducted to an outer glass layer to form a diffraction layer, and finally, a muitilayered 3D visual effect is generated, and the manufactured finished product has a good 3D effect, and is very exquisite and high-class.

Abstract: The present invention discloses an atomizing aroma diffuser which comprises an outer cover, a hollow diffuser body and a base, wherein the outer cover covers the outside of the hollow diffuser body; the upper surface of the outer cover is provided with a vent hole; the base is connected with the lower end of the hollow diffuser body; the base is provided with a fan which is electrically connected with a circuit board; a light-emitting diode (LED) light sheet is further integrated on the circuit board; a plastic partition plate with the hollow middle is arranged in the hollow diffuser body and divides the hollow diffuser body into an upper part and a lower part; a ceramic atomizing sheet is installed on the middle hollow part of the plastic partition plate and connected with the circuit board; one side wall of the hollow diffuser body is provided with an exhaust channel, and the exhaust channel penetrates the plastic partition plate; and a cover with a vent hole is further arranged above the hollow diffuser bo
