The invention provides a surgical instrument and a surgical robot adopting the surgical instrument. The surgical instrument comprises a front end, a wrist part, a foundation base, a guide mechanism and a traction unit, wherein the front end is rotatably connected with the wrist part and a first rotation axis is formed, the wrist part is rotatably connected with the foundation base and a second rotation axis is formed, and the first rotation axis and the second rotation axis are non-coplanar and are vertical to each other; the traction unit comprises a first traction body, a second traction body, a third traction body and a fourth traction body; the four traction bodies surround and are partially fixedly connected with the front end, extend, are restrained by the guide mechanism, and then are connected with an external mechanism; the second traction body surrounds the front end in the direction opposite to that of the first traction body, and the fourth traction body surrounds the front end in the direction opposite to that of the third traction body; the first traction body and the second traction body are distributed on one side of the second rotation axis, and the third traction body and the fourth traction body are distributed on the other side of the second rotation axis.

The invention relates to a coating machine, which comprises a casing, a feeding device arranged in the casing and capable of uniformly transporting medicine granules into the casing, a material bearing device arranged in the casing and receiving the medicinal granules, A spray device for spraying coating dressings, a drying device installed in the cabinet and evaporating the solvent in the coating dressing, the material receiving device includes two receiving plates arranged inside the cabinet, and the two receiving plates are installed in the cabinet and drive the two receiving plates to move relative to each other. And the rotating bearing plate driving mechanism, the feeding device includes a feeding pipe that is slidably connected to the inside of the chassis and can extend into between the two bearing plates, a storage box arranged at one end of the feeding tube away from the bearing plate, and a material storage box. And the box vibration mechanism that makes the storage box vibrate, and the feeding tube moving mechanism that is located inside the chassis and drives the feeding tube to move in the direction of the axis of rotation of the receiving plate, has the medicine particles evenly distributed on the receiving plate, so that the medicine particles can be more uniformly distributed. Coating, the effect of improving the uniformity of product coating.

The invention discloses a compressor, an air conditioner and a water heater. The compressor comprises a shell and a compression device, wherein refrigerant oil is arranged at the bottom of the shell; the compression device is arranged in the shell; the compression device comprises a crankshaft, a main bearing, a secondary bearing and a cylinder; the main bearing and the secondary bearing are arranged at the top and the bottom of the cylinder respectively and used together with the cylinder for defining a compression cavity; the lower end of the crankshaft penetrates through the main bearing and stretches into the compression cavity; a ratio of the eccentricity e of an eccentric part of the crankshaft relative to the central axis of the cylinder to the inner diameter Phi of the cylinder satisfies the following expression: e / Phi is more than or equal to 0.05 and less than or equal to 0.12. According to the compressor, the ratio of the eccentricity e to the inner diameter Phi of the cylinder is set as the following expression: e / Phi is more than or equal to 0.05 and less than or equal to 0.12. The degree of wear-out failure of a sliding sheet and the crankshaft in the compression device when the compressor runs at a high pressure and a high temperature can be reduced; the compressor is hardly worn, so that the service life of the compressor can be effectively prolonged, thus the reliability of the compressor can be improved.
