Description of the Invention: [Technical Field of the Invention] The present invention relates to a mattress for preventing acne or for helping a patient to turn over, and more particularly to a medical mattress that is mechanically undulating. [Prior Art] The present invention relates to a mattress for preventing acne or for helping a patient to turn over, and more particularly to a medical mattress that mechanically adjusts undulation. SUMMARY OF THE INVENTION An object of the present invention is to provide a mechanically adjustable undulating medical mattress in which a plurality of retractable arms are disposed in a pad body, and the retractable devices are pulled by a rope to perform telescopic movement, thereby adjusting the pad body. ups and downs. In order to achieve the above objective, the medical mattress comprises a pad body and a plurality of retractable devices, and the retractor includes a base, a push column, an elastic member and a rope. One end of the column penetrates the base and the elastic member is disposed outside the push column. The two ends of the elastic member respectively abut the push column and the base, and the elastic member pushes against the push column to displace the pad body, so that the push column The other end abuts the pad body, and the rope is connected to the end of the push column penetrating the base. Pulling the rope can interlock the displacement of the push column relative to the base and simultaneously compress the elastic member, and loosening the rope can make the push The column is reset by the restoring force of the elastic member, thereby controlling the extension or retraction of the retractor to adjust the undulation of the pad body; the mechanically controlled retractor is low in cost and controlled Pulling the distance of the rope can also be micro-201102054. Adjusting the distance between the extension and retraction of the retractor [Embodiment] The mechanical adjustment of the undulating medical bed of the present invention is carried out, for example, as shown in the figure below, 'the patient lies on the medical bed _ The schematic is shown in Figure 2, including Pad body ίο '内具-容室u' The carcass 1G is used for the patient to lie; the plurality of retractors 20 are disposed in the chamber η of the pad body 1 , and the retractors 20 are as shown in Figures 3 and 4 As shown, it comprises a base 2, a push rod 22, an elastic member 23 and a rope 24. The one end 221 of the push rod 22 penetrates into the base 2, and the push rod 22 is formed at another end-supporting piece 222. 23 sets are disposed outside the push column 22, in this embodiment, the elastic member 23 is a spring 'may be a metal or _ elastic piece, elastic rubber block and the like which are deformable and elastically resilient, and the elastic member 23 (four) respectively The top of the base 2 and the frame 22 is moved, and the elastic member 23 is pushed against the push rod 22 to be displaced toward the body 10, so that the striker 222 of the push column 22 abuts the (four) 10, and the expanders 2G and the work piece is moved to the same side of the top body 1'. The 24th end of the rope is connected to the 蚝22 of the push column 22, and the rope f24 can interlock the displacement of the push column 22 relative to the base 21 and At the same time, the elastic member 23 is compressed to retract the push column 22, and the relaxation cable 24 can push the push rod by the restoring force of the elastic member 23. 201102054 is reset to extend the push column 22; and the plurality of drawstring sets 30, as shown in Figures 3 and 4, the number of the drawstring sets 30 is the same as the number of the stretchers 20, and the drawstring sets 30 Each of the cable sets 30 includes a steering shaft 31 and a cable pulling mechanism 32. The middle portion of the steering shaft 31 is radially recessed to form a turning portion 311. The rope 24 is wound around the cable shaft 24. The steering portion 311 of the steering shaft 31 can change the extending direction of the two ends of the rope 24. The cable pulling mechanism 32 includes a limiting plate 321 , a rotating shaft 322 and a turntable 323 . The limiting plate 321 has a pivot hole A and a notch B, the shaft 322 has a protrusion C at one end thereof, and the protrusion C is disposed in the bore A of the limiting plate 321 , and the other end of the rotating shaft 322 is connected to the turntable 323 , and the rope 24 passes through the The notch B of the limiting plate 321 and the other end are fixed on the rotating shaft 322, and the rotating plate 323 has a grip D. Controlling the turntable 323 and the rotating shaft 322 to pivot relative to the limiting plate 321 by the grip D, the notch B of the limiting plate 321 can be moved and the rotating shaft 322 is pivoted relative to the notch B, since the rope 24 passes through The notch B is fixed to the rotating shaft 322. Therefore, when the notch B is not moved and the rotating shaft 322 is pivoted, as shown in FIG. 5, the rope 24 is gradually wound around the rotating shaft 322, and the retractor is gradually pulled. The push column 22 of the 20 is retracted. If the turntable 323 and the rotating shaft 322 are pivoted in the opposite direction, the rope 24 can be gradually detached from the rotating shaft 322, and the push column 22 of the retractor 20 can be subjected to the elastic member of the 201102054. The restoring force of 23 is extended to extend, thereby adjusting the body (4) undulation;
