[0059] Then, the cam 5 is driven to rotate by the pressure rod 51 on the cam 5. Since the contour line of the arc-shaped edge on the cam 5 is a Fibonacci arc, the cam 5 abuts against the bottom surface of the sliding support 43. The cam 5 can drive the sliding support 43 to move upward through its rotation, thereby driving the punching device 2 set on the sliding support 43 to move upward and punch holes upward on the high-altitude ceiling.

[0060] Compared with the prior art, the high-altitude roof upward punching device provided by the utility model has the following advantages:

[0061] (1) A cam and a pressure rod are used as a force-adding mechanism. The pressure rod drives the cam to rotate, pushing the sliding support to move upward, thereby driving the punching device set on the sliding support to move upward to punch holes. The cam and the pressure rod cooperate to change the direction of the worker's force-adding operation, reduce the size of the operating force required when operating the force-adding mechanism, and improve the control accuracy and operation convenience of the force-adding mechanism;

[0062] (2) The lifting mechanism includes inner and outer columns, and a screw and screw drive mechanism disposed in the inner and outer columns. The lifting of the inner column is controlled by a screw, which improves the control convenience and control accuracy of the lifting of the inner column and the lifting stability of the inner column relative to the outer column. A crank and a meshing crank gear and screw gear are used as the screw drive mechanism, which improves the operation convenience and control accuracy of the screw drive control.

[0063] (3) The cam is provided with an arc portion whose contour line is a Fibonacci arc. The arc portion is pressed against the bottom surface of the sliding support. The cam is driven to rotate by pressing the pressure rod downward, and the drilling device is pushed to drill, which has good drilling stability.
