In order to avoid interference between the first push rod 130 and the second push rod 140 during the left-right translation, the first pushing portion 132 is disposed higher than the second pushing portion 142. The first push rod 130 and the second push rod 140 are both disposed at the right end of the rack, so that the distance between the first push rod 130 and the second push rod 140 can be reduced, the size of the housing 100 can be further reduced, and the grooving lengths of the first and second grooves 103 and 104 can be reduced, so that the bottom plate of the housing 100 has better strength.

As shown in fig. 2 to 5, the support frame assembly includes rotatable legs disposed on left and right sides of the bottom of the housing 100, a first connection shaft 210 extending vertically downward is disposed on the right side of the bottom of the housing 100, the first connection shaft 210 is disposed between the first bar-shaped groove 103 and the second bar-shaped groove 104, and a first leg 230 and a second leg 240 capable of rotating relatively are sleeved on the first connection shaft 210; two second connecting shafts 270 extending downwards and vertically are arranged on the left side of the bottom of the shell 100, the two second connecting shafts 270 are arranged along the width direction of the shell 100, and a rotatable third supporting leg 280 is sleeved on each second connecting shaft 270; an accommodating space for the first push rod 130 and the second push rod 140 to move is provided between the upper end surface of the support leg and the bottom of the housing 100, i.e. the first push rod 130 and the second push rod 140 are disposed between the upper end surface of the support leg and the bottom of the housing 100 when viewed from the height direction.

Specifically, as shown in fig. 5, the first connecting shaft 210 is sleeved with a first stop collar 220, a first supporting leg 230, a second supporting leg 240, a gasket 250 and a nut 260 from top to bottom, wherein the supporting legs comprise a rotating part for sleeving the first connecting shaft 210 and a supporting part extending downwards obliquely from the outer edge of the rotating part, and the nut 260 is fastened with the connecting shaft 210 to press the first rotating part 231 of the first supporting leg 230 and the second rotating part 241 of the second supporting leg 240 on the bottom of the shell 100; the upper surface of the second rotating portion 241 is provided with a positioning bead 242 supported by a spring, the lower surface of the first rotating portion 231 is provided with a plurality of positioning grooves corresponding to the positioning bead 242, and the plurality of positioning grooves are circumferentially arranged on the lower surface of the first rotating portion 231 along the axis of the first connecting shaft 210, so that when the first supporting leg 230 and the second supporting leg 240 rotate, the rotating portions of the supporting legs abut against elastic pieces formed by the spring, the positioning bead 242, and can smoothly rotate to different angles under the action of the elastic force and are positioned in the corresponding positioning grooves. The second connecting shaft 270 is sleeved with a second limiting sleeve 290, a third supporting leg 280, a gasket 250 and a nut 260 from top to bottom, the third supporting leg 280 also comprises a rotating part and a supporting part extending downwards obliquely from the outer edge of the rotating part, and a positioning bead 242 supported by a spring is also arranged between the third supporting leg 280 and the second limiting sleeve 290 to enable the third supporting leg 280 to smoothly rotate.

In other embodiments, the positioning groove is not required, so that the support leg rotates at any angle; in other embodiments, the elastic member may also replace the positioning bead and the positioning groove with a wave spring washer, and after the nut and the connecting shaft are fastened with a certain pretightening force, the supporting leg is shifted, and after overcoming the friction force of the wave spring washer, the supporting leg may also rotate relative to the connecting shaft. Preferably, the structure of the positioning beads and the positioning grooves is adopted, so that the supporting legs can be positioned after rotating to different positions, and the pressing assembly can be supported more stably.

Further, as shown in fig. 6, the first leg 230 and the second leg 240 are configured to be capable of being stacked up and down, that is, when the first leg 230 and the second leg 240 are selected to be at the same angle, the first leg 230 is integrally stacked above the second leg 240, so that a plurality of legs can be better stored together.

The support frame assembly of the embodiment lifts the height of the pressing assembly and the height of the air bag, and when in actual use, the pressing assembly and the air bag can be lifted to the upper part of the body of a patient, so that only the support frame assembly needs to occupy the position of a sickbed, the support legs of the support frame assembly are rotatable, the directions of the support legs can be adjusted according to the actual space of the sickbed, the use is flexible, and the occupied space of the automatic pressing device is greatly reduced; the support legs are provided with the support parts extending obliquely, so that a stable conical structure can be formed to support the pressing assembly at the upper part when the support legs are unfolded to different angles; in addition, when the support leg is rotated to the inner side of the housing 100, the storage space can be reduced, and the support leg is convenient to place.

Further, the first leg 230, the second leg 240 and the third leg 280 may be configured to be telescopic, so that the height of the pressing assembly is adjustable, and the use is more convenient.
