The invention relates to the technical field of agricultural automatic picking equipment, and discloses a tail end grabbing mechanism for picking fruits and vegetables, the tail end grabbing mechanism for picking fruits and vegetables comprises a tail end grabbing mechanism body arranged on a picking mechanical arm, and the tail end grabbing mechanism for picking fruits and vegetables utilizes the arrangement of a movable assembly and the cooperation of bevel gear transmission and thread adjustment to grab the fruits and vegetables. When the flexible fingers clamp fruits and vegetables, a driving block is triggered to slide, a bevel gear is driven by a sliding rod and a rotating shaft to perform transmission, and finally the transmission is converted into lifting motion of a threaded rod and the abutting disc, so that an adaptive clamping space can be provided for picking the fruits and the vegetables, and the abutting disc can be attached to the tops of the fruits and the vegetables during placement to buffer fruit and vegetable falling rebound force; meanwhile, the driving block can be automatically reset through the reset spring, the cyclic operation efficiency of the mechanism is improved, the picking and placing safety is guaranteed, and the risk that fruits and vegetables are damaged is reduced.

The utility model relates to power grounding detection technical field, concretely relates to a kind of for low-voltage power system grounding detection mechanism, including detection check appearance body, two connecting jacks are opened in the front of detection check appearance body, connecting plug is inserted in connecting jack, connecting plug is installed with connecting wire, the outside of two connecting jacks is provided with anti-drop positioning mechanism, anti-drop positioning mechanism includes two mounting blocks fixedly installed in the front of detection check appearance body, first guide rod is connected with the transverse sliding of mounting block and is penetrated, the end of first guide rod away from connecting plug is fixedly connected with limit block, the other end of first guide rod is fixedly connected with arc anti-drop block, two arc anti-drop block top are fixedly connected with fixed block, spring is fixedly connected between arc anti-drop block and mounting block;The present application can limit connecting plug, prevent the end part of connecting plug from separating from inside connecting jack, facilitate the normal use of detection check appearance body.

The utility model discloses a heavy -duty cable protection pipe orifice sealing locking device is constituted by split type elastic sealing sleeve and detachable locking assembly, wherein elastic sealing sleeve adopts two symmetrical axial division's half casing structure, has the circular cylindrical inner contour passageway of through axial with truncated cone shape outer contour, and the interference seal is formed to the smaller inside diameter than cable outside diameter. The sleeve outer surface is equipped with annular groove, realizes radial pressure fixed through the locking assembly of throat clamp. Elastic sealing sleeve adopts natural rubber material, and the exposed portion accounts for 1 / 4 of the overall length when installing. The device realizes multiple sealing between cable and protection pipe through the elastic deformation of rubber sleeve, and effectively blocks the invasion of moisture and foreign matters, and the conical structure cooperates with the exposed length to significantly reduce the pulling resistance, and the annular groove and the throat clamp size match to ensure that the locking force is evenly distributed, and the device has the convenience of installation, sealing reliability and maintenance economy, and is especially suitable for the pipe orifice sealing protection of cable bridge lower bending pass.

The utility model relates to the technical field of traditional Chinese medicine cleaning, in particular to cleaning equipment for traditional Chinese medicine decoction piece production, which comprises a support, an arched protective cover is arranged above a support body, and a plurality of water spray pipes are arranged on the inner wall of the top end of the protective cover; a driving shaft and a driven shaft are symmetrically arranged on the two sides of the top of the support through bearing seats respectively, a first rolling ring and a second rolling ring are arranged at the front end and the rear end of a driving shaft body and the front end and the rear end of a driven shaft body respectively, U-shaped grooves are formed in the first rolling ring and the second rolling ring, and rotating wheels matched with the U-shaped grooves are arranged on the driving shaft and the driven shaft in a penetrating mode. A plurality of brush plates are arranged between the first rolling ring and the second rolling ring, bristles are arranged on the inner surfaces of brush plate bodies, and the bristles brush traditional Chinese medicinal materials through rotation; the cleaning equipment can avoid damage to skins of rhizome traditional Chinese medicinal materials caused by collision or extrusion, and meanwhile, continuous cleaning can be realized, so that the labor intensity of workers is reduced.

The utility model discloses an adjustable multifunctional protective restraint appliance for psychiatry department in the technical field of medical nursing instruments, which comprises a restraint strap and a fixing strap, an adjusting component is arranged on one side of the restraint strap, one side of the adjusting component far away from the restraint strap is fixedly connected with the fixing strap, and the other end of the fixing strap is connected with a nursing bed; the adjusting assembly comprises an adjusting sleeve part axially and fixedly connected to one side of the restraint strap in a sleeving mode, an adjusting shaft is rotationally connected to the center of the adjusting sleeve part, the adjusting shaft perpendicularly penetrates through the adjusting sleeve part and the restraint strap and is rotationally connected with the inner walls of the two sides of the adjusting sleeve part, and the adjusting shaft located in the adjusting sleeve part is meshed with a toothed belt assembly. The fixing device is novel and perfect, unlocking is achieved by pressing the knob, the adjusting shaft is rotated to drive the toothed belt assembly to collect or loosen the restraint strap, the knob is loosened to be locked again, limbs of a patient are wrapped under the appropriate tightness of the adjusting strap, and the length of the fixing strap is adjusted through the length adjuster to restrain the limbs of the patient from swinging. Therefore, the convenience and the safety of the adjustment operation are enhanced.
