The movable rectangular cylinder 1001 is fixedly arranged at the bottom of the workbench 306, the movable ladder 1003 is fixedly arranged on the movable rectangular cylinder 1001, the L-shaped block 1006 is symmetrically fixedly arranged on the movable rectangular cylinder 1001, the vertical plate 1005 is fixedly arranged on the rectangular box 601, the movable rectangular cylinder 1002 is slidably arranged on the vertical plate 1005, the movable ladder 1004 is fixedly arranged on the movable rectangular cylinder 1002, and the slot 1007 is symmetrically fixedly arranged on the movable rectangular cylinder 1002.

[0029] like Figure 1 , Figure 2 , Figure 8 , Fig. 9 , Fig.10 As shown, the fixed lifting assembly 9 includes a fixed column 901 , a stopper 902 and a fixed ladder 903 . The fixed column 901 is fixedly arranged on the top of the rectangular box 601 , the stopper 902 is symmetrically arranged on both sides of the fixed column 901 , and the fixed ladder 903 is fixedly arranged on the fixed column 901 .

[0030] When in use, after the staff enters the workbench 306, they can lift the workbench 306 and start the motor 602. The motor 602 drives the circular plate 603 to rotate. The circular plate 603 drives the connecting rod 604 to reciprocate back and forth. The connecting rod 604 drives the rubber block 605 to reciprocate back and forth. When the rubber block 605 moves backward, it generates suction on the convex column 704 and the one-way plate 608. The convex column 704 is forced to move backward along the U-shaped frame 702. The spring 1 703 is compressed. When the top of the convex column 704 moves to the columnar tube 7 01, the outside of the device is connected with the inside of the columnar tube 701 through the rectangular opening 705, so that the air outside the device is sucked into the rectangular box 601 through the columnar tube 701, and the one-way plate 608 remains motionless under the limit of the rectangular box 601. When the rubber block 605 moves forward, it generates a thrust on the convex column 704 and the one-way plate 608. The convex column 704 is automatically reset by the force, and the one-way plate 608 is forced to open upward, so that the movable tube 2 304 is connected with the rectangular box 601, and the internal air is pushed into the movable tube 2 304. The rubber block 605 is as shown in FIG. This reciprocating motion causes the movable cylinder 2 304 to gradually move upward under the action of air pressure, and the movable cylinder 2 304 drives the limiting ring 2 305 and the working platform 306 to move upward together, until the limiting ring 2 305 contacts the top inner wall of the movable cylinder 1 302, and the movable cylinder 2 304 can drive the movable cylinder 1 302 and the limiting ring 1 303 to continue to move upward together, until the limiting ring 1 303 contacts the top inner wall of the fixed cylinder 301, that is, the working platform 306 reaches the maximum limit that can be raised. When it needs to be lowered, the electric telescopic rod 802 is controlled to drive the column The block 803 moves outward, the columnar block 803 drives the wedge plate 804 to move outward, the wedge plate 804 drives the longitudinal slide plate 806 to move upward along the limit plate 805, and the longitudinal slide plate 806 lifts the one-way plate 608, so that the interior of the multi-stage lifting mechanism 3 is connected with the rectangular box 601. When the columnar block 803 is completely moved out of the air outlet 607, the gas inside the multi-stage lifting mechanism 3 gradually flows out of the air outlet 607 through the rectangular box 601, thereby causing the movable cylinder 1 302 and the movable cylinder 2 304 to gradually descend, that is, driving the workbench 306 to gradually descend.

[0031] When the workbench 306 rises, it will also drive the movable rectangular cylinder 1001 and the movable ladder 1003 to rise together. The movable rectangular cylinder drives the L-shaped block 1006 to rise together. When the L-shaped block 1006 is completely inserted into the slot 1007, the movable rectangular cylinder 1001 drives the movable rectangular cylinder 2 1002 and the movable ladder 2 1004 to rise along the vertical plate 1005 through the L-shaped block 1006. When the workbench 306 rises to the highest point, the fault auxiliary rescue mechanism 5 is also deployed.

[0032] When moving horizontally, in order to ensure a safe distance between the workbench 306 and the machine body and prevent the workbench 306 from colliding with the machine body, an anti-collision automatic alarm mechanism 4 is set. When the distance from the machine body exceeds the safe range, the cross plate 1108 will first come into contact with the machine body, and the machine body will squeeze the cross plate 1108. The cross plate 1108 is forced to move backward, and the cross plate 1108 drives the short tube 1107 to move backward. The short tube 1107 drives the sliding block 1103, the connecting block 1109 and the trapezoidal plate 1110 to move backward together. The spring three 1102 and the spring four 1104 are both compressed. When the trapezoidal plate 1110 moves backward, the movable block 1206 is squeezed, and the movable block 1206 gradually moves downward. 06 drives the triangular block 1207 and the limit block 1208 to move downward. When the triangular block 1207 moves to the bottom of the truncated cone block 1105, the elasticity of the spring four 1104 is released, and the truncated cone block 1105 drives the trigger rod 1106 to eject backward. When the truncated cone block 1105 moves to the bottom of the connecting tube 1101, the trigger rod 1106 is squeezed with the pressure sensor 1203, and the pressure sensor 1203 transmits the signal to the buzzer 1204, and the buzzer 1204 can alarm to remind the operator. To cancel the alarm, just move the trigger rod 1106 to the left, so that the trigger rod 1106 drives the truncated cone block 1105 to move to the left side of the triangular block 1207, and the alarm can be canceled and the anti-collision automatic alarm mechanism 4 can be automatically reset.
