Background
Most of the traditional telescopic mechanisms are pneumatic telescopic mechanisms and hydraulic telescopic mechanisms, the telescopic mechanisms are pushed by air pressure and hydraulic pressure to realize telescopic operation, and air (or liquid) is input and drawn back into the telescopic sleeve by an air pump (or a liquid pump) at high pressure to push the telescopic rod to extend and retract. In practical operation, because of the more junction, high pressure work, the frequent emergence gas leakage (or weeping) causes the pressure insufficient, and the dynamics and the duration change of extension, withdrawal are up to standard, and probably directly produce the defective products, influence normal production, exist inefficiency, fault rate height, even objective inadequacies such as economic loss.
Meanwhile, because the integral structural parts comprise parts such as an air pump (or a liquid pump), gas (or liquid), a telescopic tube and the like, the structure is complex, the parts are numerous, and the sealing requirement is high, so that the production cost is increased.

Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Specific examples:
in this embodiment, as shown in fig. 1 and 2, a profile wheel driving telescopic mechanism comprises a driving shaft 1, a profile wheel, a telescopic rod, a spring 5 and a pair of positioning sleeves 6;
the special-shaped wheel is arranged as a horizontal round wheel 3, and a special-shaped protruding block 2 formed by connecting an elliptical arc edge 21, an arc edge 22 and a straight line edge 23 end to end is fixedly arranged in the center of the top surface of the round wheel 3; the peripheral wall of the special-shaped protruding block 2 and the top surface of the round wheel 3 form a circle of steps;
