The sterile state of the needle head before each use is ensured, the infection risk is effectively reduced, and meanwhile, the use convenience is improved.

The utility model relates to the technical field of warning lamps, in particular to a warning lamp device for a road, which comprises a warning lamp device body for the road, the warning lamp device body comprises a foundation plate, universal wheels and a stabilizing component are mounted at the bottom of the foundation plate, a mounting cylinder is fixedly mounted on the side edge of the foundation plate, and an anti-collision component is arranged on the mounting cylinder. Lifting rods are fixedly installed on the upper side of the foundation plate, jacking columns are fixedly installed at the upper ends of the lifting rods, and supporting rods are fixedly installed on the side edges of the jacking columns. The anti-collision assembly is arranged, a protective net in the anti-collision assembly provides a protective barrier for the periphery of the whole device, the sponge sleeves arranged on the stand columns in a sleeving mode can absorb energy generated by collision when collision occurs, damage caused by collision is prevented, and meanwhile the anti-collision reflective stickers arranged on the outer side of the stable top frame also play an anti-collision warning role; and accidental impact caused by insufficient light at night is prevented, the service life of the device is prolonged, and meanwhile the use safety is enhanced.

The utility model relates to the technical field of landscaping, and discloses a landscaping pruning device which comprises pruning shears, connecting cylinders and screws are fixedly mounted at the two ends of the bottom of the pruning shears, connecting columns are slidably mounted at the bottoms of the connecting cylinders, first sliding grooves are formed in the two sides of an inner cavity of each connecting cylinder, and the first sliding grooves are communicated with the first sliding grooves. First sliding blocks are installed in the two first sliding grooves in a sliding mode. Through the connecting cylinder and the connecting column, the length of the pruning shears can be automatically adjusted, branches of different heights can be pruned, a ladder or a climbing tool is not needed for approaching the branches, time and labor are saved, the requirement for high-altitude operation can be reduced, therefore, the working risk is reduced, and the safety of a user is protected; according to the pruning shears, the two ends of the pruning shears can be fixed together, the cutting edge of the pruning shears is prevented from accidentally injuring others or themselves, meanwhile, the cutting edge is prevented from being accidentally impacted or scratched, the service life of the pruning shears is prolonged, and a user can conveniently carry the pruning shears.

The utility model relates to a working platform, in particular to a high-safety aerial working platform which comprises a base, a plurality of lifting rods are arranged above the base, a third motor drives a connecting plate to rotate to a horizontal angle, and a fourth motor drives a third connecting rod and a fourth connecting rod to rotate to a proper angle. The lower ends of a third connecting rod and a fourth connecting rod are attached to the ground, a fifth motor drives a step plate to rotate to a horizontal angle so that operators can better get on and off the platform more safely, and a first hydraulic rod drives an illuminating lamp to ascend to a proper height so that the illuminating lamp can be better suitable for the operators with different heights.
