Drive the roller frame II7-3 and gear II7-5 to move to the left, the gear II7-5 and the rack II2-7 are meshed and connected to drive the gear II7-5 to rotate, the gear II7-5 drives the wheel frame shaft II7-2 to rotate, and the gear II7-5 rotates. The frame rotating shaft II7-2 drives the roller frame II7-3 and the two rollers II7-4 to the vertical state, and the two rollers II7-4 are in contact with the ground and slide, which is convenient for the movement of the device. When the retractable roller mechanism I6 and the retractable roller mechanism II7 are respectively accommodated at the lower ends of the fixed frame body 1 and the movable frame body 2, when the fixed frame body 1 or the movable frame body 2 is moved under the patient, the rollers I6-4 The roller II 7-4 is in contact with the ground and slides on the ground, reducing friction to facilitate the movement of the fixed frame body 1 and the movable frame body 2 on the ground so as to conveniently move under the patient.

The working principle of a nursing and medical stretcher of the present invention: when the present invention is in use, when two hand grips 3 are held, the thumbs of both hands press the two linkage control mechanisms 4 to control the two clamping mechanisms 5 and the fixing frame When the body 1 is separated, the movable frame body 2 can slide in the fixed frame body 1, so as to adjust the overall length of the fixed frame body 1 and the movable frame body 2, which is suitable for patients of different heights. After the thumb on the upper part, the two locking mechanisms 5 are stuck on the fixed frame body 1, and the overall length of the movable frame body 2 and the fixed frame body 1 is fixed, and the two linkage control mechanisms 4 are pressed all the time and the movable frame body 2 is pulled outward. The movable frame body 2 can be pulled out from the fixed frame body 1 to realize the separation of the movable frame body 2 and the fixed frame body 1, and it is convenient to adjust the overall length of the movable frame body 2 and the fixed frame body 1 when holding the forehand and the backhand. Or control the movable frame body 2 to be separated from the fixed frame body 1. When the medical staff is inconvenient to lift the patient as a whole, the lower body of the patient can be lifted to the fixed frame body 1 alone, and the upper body of the patient can be lifted to the movable frame body 2. , and fasten the fixed frame body 1 and the movable frame body 2. When necessary, manually adjust the retractable roller mechanism I6 and the retractable roller mechanism II7 to the vertical state, which is convenient for the movement of the device and saves the physical strength of medical staff. When the mechanism I6 and the retractable roller mechanism II7 are respectively accommodated at the lower ends of the fixed frame body 1 and the movable frame body 2, when the fixed frame body 1 or the movable frame body 2 is moved under the patient, the roller mechanism I6 and the retractable roller mechanism can be accommodated. The mechanism II7 is in contact with the ground and slides on the ground, reducing friction to facilitate the movement of the fixed frame body 1 and the movable frame body 2 on the ground.

Of course, the above description does not limit the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the essential scope of the present invention also belong to the present invention. protected range.
