Another three inner T-shaped brackets 15 are also fixedly arranged on the second inner platform 4. The upper ends of the inner T-shaped brackets 15 are fixedly connected to a first inner platform 2. A lifting sleeve 13 is fixedly connected between the first inner platform 2 and the second inner platform 4. A lifting mechanism for driving the lifting sleeve 13, the first inner platform 2 and the second inner platform 4 to lift is arranged on the lower side of the third platform 5. A rotatable support platform mechanism is connected to the upper side of the first inner platform 2.
