the conversion bed body (32) comprises a conversion bed body (321), an extension rod (322), a pulley (323), a first air bag (324), a second air bag (325), a first gear (326) and a clamping ring (327); the conversion bed body (321) comprises a first cross rod (3211) and a first connecting column (3212); the number of the first cross rods (3211) is the same as that of the support rods (11), the first cross rods (3211) are all of a hollow revolving body structure, and the first cross rods (3211) form a grid-shaped conversion bed body (321) through a first connecting column (3212); two ends of each first cross rod (3211) are slidably connected with an extension rod (322), and one end of each extension rod (322) can slide in the first cross rod (3211); the other end of the extension bar (322) is connected with a rotatable pulley (323); when the sliding mechanism (31) drives the conversion bed body (321) to ascend, the pulley (323) on the extension rod (322) slides in the wheel sliding groove (a) on the inner side of the support rod (11), and the conversion bed body (321) slides in the rod sliding groove (c) on the inner side of the vertical rod (13); along with the continuous rising of the conversion bed body (321), the extension rod (322) continuously slides towards the first cross rod (3211) so that the length of the conversion bed body (32) is continuously reduced; when the sliding mechanism (31) drives the conversion bed body (321) to descend, the extension rod (322) continuously slides towards the first cross rod (3211) so that the length of the conversion bed body (32) is continuously increased; therefore, the conversion bed body (32) can not only move up and down to adjust the height, but also automatically adjust the length, the first air bag (324) is fixedly connected to the upper surface of the conversion bed body (321), the second air bag (325) is hinged to the left end and the right end of the conversion bed body (321), the second air bag (325) is distributed on the upper surface of the extension rod (322), and the first air bag (324) and the second air bag (325) are both connected with an external air pump; the first air bag (324) is inflated, the conversion bed body (321) can be used as a common bed, and people can feel softer and more comfortable when lying on the first air bag (324) than the common bed; first air bags (324) at two ends of the conversion bed body (321) are inflated, so that the length of the conversion bed body (32) can be increased, and first gears (326) and clamping rings (327) are mounted at four corners of the conversion bed body (321);

the number of the protection devices (4) is two, and the two protection devices (4) are respectively arranged on the front side and the rear side of the conversion bed body (321); the two protection devices (4) respectively comprise a rotating shaft (41), a second gear (42), a first motor (43) and a protection plate (44); the rotating shaft (41) is hinged to a first cross rod (3211) on the outer side of the conversion bed body (321); two ends of the rotating shaft (41) are connected with a second gear (42), and the second gear (42) is meshed with the first gear (326); one end of the rotating shaft (41) is also provided with a first motor (43) which drives a second gear (42) to rotate; a protective plate (44) is welded on the surface of the rotating shaft (41);

the hammock body also comprises hooks (23), the hooks (23) are connected at four corners of the bed cloth (21), and the hooks (23) can be hooked on the clasps (327) of the conversion bed body (32), so that the bed cloth (21) can be used as a hammock, a comforter or a bed sheet; four corners of the bed cloth (21) are connected to the sleeve (142) through ropes (22), and the rotating rod motor (144) works to drive the rotating gear (143) to rotate, so that the connecting rod (141) moves up and down along the outer side wall of the supporting rod (11), and the bed cloth (21) can slide up and down;

the protective plate (44) comprises a second cross rod (441) and a second connecting column (442); the second cross rod (441) and the second connecting column (442) are connected in a staggered manner to form a latticed protective plate (44); when the conversion bed body (32) rises to a high place, the protection plate (44) can be used as a stair;

when the hammock is in work, when people like the hammock to shake and feel comfortable, people can lie on the bed cloth (21), the visual fields at different heights are different, the enjoyable scenery is also different, people can turn on the switch of the rotating rod motor (144), so that the rotating gear (143) drives the connecting rod (141) to slide up and down, the hammock body (2) is adjusted to a proper height according to personal preferences, and then the switch of the rotating rod motor (144) is turned off, so that the bed cloth (21) stays at the most proper height;

when people do not like the shaking feeling of the bed body and want to lie on a stable bed body, people can use the conversion bed body (32), people turn on the switch to enable the sliding mechanism (31) to work, drive the conversion bed body (32) to move upwards, adjust the conversion bed body (32) to a proper height according to personal preference of watching landscapes, and then turn off the switch of the sliding mechanism; at the moment, if people do not want to lie on the first air bag (324) directly, the rotating rod motor (144) can work to drive the connecting rod (141) to move downwards, so that the bed cloth (21) descends to the upper surfaces of the first air bag (324) and the second air bag (325), and then the clamping hook (23) on the hammock body (2) hooks the clamping ring (327) on the conversion bed body (32), so that the bed cloth (21) can be used as a bed sheet; if the outside air temperature is low, people can separate the hook (23) and the snap ring (327), and people directly lie on the first air bag (324), so that the bed cloth (21) is used as a quilt, and the function of keeping out cold is achieved;

when people come close to a beast outdoors, people can open a switch of a first motor (43), a rotating shaft (41) drives a second gear (42) to rotate, so that protective plates (44) connected to the front side and the rear side of a conversion bed body (321) rotate towards a supporting rod (11), when the rotating shaft is rotated to be in contact with the supporting rod (11), a clamping claw (12) starts to work, the protective plates (44) are clamped and fixed on the supporting rod (11) by the clamping claw (12), and therefore people are protected in a hammock, and people are prevented from being attacked by the beast;

the conversion bed body (32) is placed indoors, and the conversion bed body (32) can also be used as a sleeping tool for daily use of people.
