When the person is transferred to the bed, the armrest sets upwards lift the human body to the position over the bed, the two armrests of each armrest set alternately go down and retreat until the person is placed on the bed. Accordingly, a patient can be automatically transferred between the bed and the armchair.

Improved structure of shoes for jumping
The invention relates to an improved structure for a bouncing shoe, which comprises at least one arched leaf spring; one side of a concave surface of the leaf spring is provided with a connecting support; the upper end of the connecting support is rotationally connected with the upper end of the leaf spring and the lower end of the connecting support is rotationally connected with a foot treadle; the bottom surface of the feet treadle is rotationally connected with one end of a stand bar the other end of which is directly rotationally connected with one side of the concave surface on the lower middle part of the leaf spring; the width and the thickness of the leaf spring are gradually widened and thickened from both ends to the middle part; and the widest position and the thickest position of the leaf spring are positioned on a joint of the other end of the stand bar and the leaf spring. In the structure, the stand bar is directly rotationally connected with the leaf spring, a bottom provided with a U-shaped groove is saved and a pivot point is increased, so that the structure makes the whole section of the leaf spring generate elastic deformation and be capable of being fully deformed to store energy, thereby improving the elasticity of the leaf spring and strengthening the entertainment. Moreover, the maximum stress point of the whole leaf spring is dropped on the maximum stress surface during the use process, so the structure strengthens the stability and the safety of products.

Novel backhoe loader
PendingCN110397103ASolve functionSolve efficiency problemsMechanical machines/dredgersState of artEngineering
The invention provides a novel backhoe loader. The novel backhoe loader solves the problem that in the prior art, an engineering machine only has a single function and is low in construction efficiency. The novel backhoe loader comprises a movable vehicle body. A loading portion is arranged at one end of the vehicle body, and an excavation portion is arranged at the other end of the vehicle body.A cab is further arranged on the vehicle body and located between the loading portion and the excavation portion. The loading portion is located on the center line in the front-back direction of the vehicle body. The cab is located on one side of the center line. One side of the cab is further provided with a standby platform used for storing accessories. The excavation portion comprises a first rotating base and an excavation big arm installed on the first rotating base. The first rotating base drives the excavation big arm to rotate by 360 degrees in the horizontal plane. When the excavationbig arm rotates to be in the same direction with the front-back direction of the vehicle body, the excavation big arm is located on one side of the cab, and the tail end of the excavation big arm islocated on the standby platform. The novel backhoe loader is simple in structure and convenient to use, has multiple functions, can cooperate to complete multiple different operations, greatly improves the construction efficiency and has good practicability.
