The invention concerns a motor vehicle comprising a structure with a first floor (10), the first floor (10) including a substantially flat raised first zone (11) and a low zone (12) adjacent the first zone (11). The low zone (12) is surrounded by a raising frame (14), a second floor (15) being mechanically fixed on the frame (14) in a plane aligned with that of the first zone (11).

The invention provides a device for shoveling fallen leaves on a community lawn with deformable local parts and a using method, and relates to the field of garden equipment. The device for shoveling the fallen leaves on the community lawn with the deformable local parts comprises a leaf fishing treatment box, wherein side boxes are bonded to the side walls of the leaf fishing treatment box, a lever lifting mechanism is arranged at the top of the leaf fishing treatment box, a top fixing plate is arranged above the leaf fishing treatment box, side feet are welded to the four corners of the bottom of the top fixing plate, side bottom rods are bonded to the bottoms of the side feet, and the bottoms of the side bottom rods are inserted into the tops of side bottom cylinders. According to the device for shoveling the fallen leaves on the community lawn with the deformable local parts, when an end arc rod makes contact with a heavy object, a close connecting rod making contact with the heavy object is bent in the clockwise direction, meanwhile, the end arc rod and the close connecting rod can also be bent, the fallen leaves are shoveled by other parts not making contact with the heavy object normally, therefore, by means of the device, heavy objects such as stones and the like can be removed, operation of the device is prevented from being affected, and meanwhile, the fallen leaves in some narrow positions can be conveniently fished out.

The invention relates to the field of lung capacity training equipment, in particular to a medical lung capacity training equipment and its working method, comprising an air blowing mechanism, a lung capacity detection mechanism, a booster mechanism and an anti-suckback device, the anti-suckback device includes a branch pipe, a standpipe, an oxygen tank, a horizontal pressing mechanism, an opening and closing mechanism, two lifting mechanisms and a connecting mechanism, and the two connecting mechanisms are respectively fixedly installed on both sides of the branch pipe. Oxygen undergoes transitional pollution. When the patient is inhaling, the anti-suckback device can allow the patient to inhale the oxygen in the oxygen tank in time, and the patient's mouth does not need to be removed from the flat mouthpiece during the inhalation process. , and the blown gas will not return to the patient's lungs, preventing germs from returning to the patient's lungs along the blown gas, reducing the possibility of the patient's illness and improving the enthusiasm of the patient.
