The working principle is as follows: the operating handle 31 is rotated to drive the second rotating rod 29 and the second bevel gear 28 and the third bevel gear 32 fixedly connected to the second rotating rod 29 to synchronously rotate, because the first bevel gear 27 and the second bevel gear 28 are in a meshed state, the first bevel gear 27 and the second bevel gear 25 rotate around the axis of the first bevel gear 27 to drive the sixth lantern ring 24 sleeved at one end of the second bevel gear 25 far away from the first bevel gear 27 to do circular motion, because the upper end of the fifth connecting rod 23 is fixedly connected to the outer ring surface of the sixth lantern ring 24, the fifth connecting rod 23 moves up and down, so that the end of the rocking handle 17 hinged with the U-shaped block 22 is pulled to move up and down, when the end of the rocking handle 17 hinged with the U-shaped block 22 moves to the highest position, the first rotating pin 18 moves towards the direction close to the disc 11 to drive the end of the first traction rod 19 far away from the first rotating pin 18 to push the cylinder 1111, the disc 11 is rotated counterclockwise, the second rotating pin 20 moves in the direction far away from the disc 11, the end of the second draw bar 21 far away from the second rotating pin 20 is no longer clamped with the cylinder 1111 and is overlapped on the cylinder 1111 under the action of gravity, when the end of the crank 17 hinged with the U-shaped block 22 moves from the highest position to the lowest position, the first rotating pin 18 moves in the direction far away from the disc 11, the end of the first draw bar 19 far away from the first rotating pin 18 is no longer clamped with the cylinder 1111 and is overlapped on the cylinder 1111 under the action of gravity, and the second rotating pin 20 moves in the direction close to the disc 11, so that the end of the second draw bar 21 far away from the second rotating pin 20 pushes the cylinder 1111 to drive the disc 11 to rotate counterclockwise, that is, during the up-and-down reciprocating motion of the end of the crank 17 close to the U-shaped block 22, the disc 11 is in the state of clockwise rotation, the inverted hook groove arranged at one side of the disc 11 far from the cylinder 1111 continuously pushes the block 14, and due to the action of the torsion spring 15, the block 14 is always in the state of abutting against the disc 11, because the two ends of the rotating shaft 9 are respectively connected with one fixed seat 10, at this time, the rotating shaft 9 rotates counterclockwise, the upper end of the traction wire 8 is continuously wound on the outer ring surface of the rotating shaft 9, the counterweight block 6 is pulled to move upwards until the third movable rod 413 slides into the second movable rod 412 and the second movable rod 412 slides into the first movable rod 411, at this time, the telescopic rod 4 is in the shortest state, i.e., the lamp body 518 reaches the highest position, after the lamp body 518 is raised to an appropriate height position, the rotation of the operating handle 31 is stopped, because one end of the second traction rod 21 far away from the second rotating pin 20 is in a clamping state with the cylinder 1111, the disc 11 cannot rotate reversely, and the height of the lamp body 518 is fixed;

when the height position of the lamp body 518 needs to be lowered, the operating handle 31 is pushed until the third bevel gear 32 comes into engagement with the first bevel gear 27 of the second group of traction mechanisms, at which time the second bevel gear 28 no longer engages with the first bevel gear 27 of the first group of traction mechanisms, because the two groups of traction mechanisms are arranged at 180 degrees, the operating handle 31 is rotated at the moment, the disc 11 of the second group of traction mechanisms and the disc 11 of the first group of traction mechanisms rotate in opposite directions, thereby driving the rotating shaft 9 to rotate reversely, shortening the length of the traction wire 8 wound on the outer ring surface of the rotating shaft 9, lengthening the telescopic rod 4 by the counterweight block 6 under the action of gravity, reducing the height position of the lamp body 518, meanwhile, after the height position of the lamp body 518 is lowered to a proper height position, the operation handle 31 stops rotating, the second group of second traction rods 21 limit the disc 11 to rotate reversely, and the height position of the lamp body 518 is fixed;

when any group of traction mechanism operates, because the two disks 11 rotate in opposite directions, the inclined surface of the inverted hook groove of the other group of disks 11 can push the fixture block 14 to rotate in a direction close to the rotating shaft 9 by the axis of the connecting shaft 13, after the disks 11 rotate at the position angle of one inverted hook groove, the fixture block 14 is under the elastic action of the torsion spring 15, and the fixture block 14 is continuously abutted against the next inverted hook groove, so that the rotating shaft 9 cannot rotate.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
