Because the nitrogen cylinder has two balance points, namely heavy load balance and no load balance, the balance can be broken by applying a small external force. The scheme adopts the first nitrogen cylinder 15 and the second nitrogen cylinder 22 to realize power balance, so that the position of the end head 30 is quickly and freely adjusted or the lower body is lifted, the operation is simple, and time and labor are saved.

The utility model discloses a theory of operation is: the smoke cage is first secured to the end 30. When the position of the smoke cage, i.e., the end 30, including the angle and height adjustment, needs to be adjusted, the position of the end 30 can be flexibly and quickly adjusted by grasping the end 30 with a hand and applying a little force. When the grip tip 30 is moved forward by hand, the second nitrogen cylinder 22 is extended; the first nitrogen cylinder 15 is extended when the head 30 is moved upward. Similarly, when the grip 30 is moved backward or downward by hand, the second nitrogen cylinder 22 and the first nitrogen cylinder 15 are contracted accordingly. The position of the end 30 in the horizontal direction can be adjusted by adjusting the first rotating mechanism and the second rotating mechanism.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
