when the teaching stick is used, the air bag type handle is held by a hand to press the air bag type handle to enable the air bag type handle to deform inwards, then air pressure is generated in an inner cavity of the air bag type handle, the air pressure is aerodynamic force, the aerodynamic force pushes the inner buckle type expansion joint with the smaller inner diameter to slide in the inner buckle type expansion joint with the larger inner diameter and extend outwards, when the outer ring of the inner buckle type expansion joint with the smaller inner diameter is clamped at the inner buckle ring hole of the inner buckle type expansion joint with the larger inner diameter, the extension is stopped, and when all the inner buckle type expansion joints except the inner buckle type expansion joint with the largest inner diameter extend outwards to the longest position, the automatic extension of the teaching stick is completed; meanwhile, the aerodynamic force pushes the central part of the pneumatic diaphragm or the whole pneumatic diaphragm to move towards the tail end of the tip of the telescopic joint after passing through the inner cavity of the inner buckled telescopic joint so as to enable the contact head to be in contact with one end of the battery, and then the power-on circuit of the illuminator is switched on so as to enable the illuminator to emit light; when light irradiates on the characters or the patterns on the blackboard, the brightness of the characters or the patterns is increased, the brightness can guide the attention of students to be focused on the characters or the patterns with the brightness, and the teaching quality is improved;
when the teaching stick is not used, the deformed air bag type handle is restored to the original state under the driving of the self deformation return function after the air bag type handle is released by hands; at the moment, suction is generated in the inner cavity of the air bag type handle, the stretched inner buckled type expansion joint is pulled to contract towards the inner cavity of the inner buckled type expansion joint with the inner diameter being one type, meanwhile, the suction generated in the inner cavity of the air bag type handle also pulls the contraction joint tip to move towards the inner cavity of the inner buckled type expansion joint with the smallest inner diameter until the inner buckled type expansion joint and the outer ring protrusion of the contraction joint tip are clamped at the inner ring protrusion of the inner buckled type expansion joint with the inner diameter being one type, and the teaching stick is automatically contracted; meanwhile, when the pointer contracts, the pressure pressed on the pneumatic diaphragm disappears, the pneumatic diaphragm moves towards the end part of the end, with the outer ring projection, of the telescopic joint tip under the driving of the self elastic return function, the contact head is driven to move backwards to be separated from one end of the battery, and the power supply circuit of the illuminator is disconnected to stop emitting light.
2. The pneumatic telescopic luminous pointer as claimed in claim 1, wherein: in order to increase the sealing effect between the two inner buckle type expansion joints, a rubber sealing ring can be arranged between the outer ring bulge and the inner ring bulge of the sealing surface of the two inner buckle type expansion joints.
3. The pneumatic telescopic luminous pointer as claimed in claim 1, wherein: in order to increase the sealing effect between the inner buckle type expansion joint and the contraction joint tip, a rubber sealing ring can be arranged between the sealing surface of the inner ring protrusion of the inner buckle type expansion joint and the outer ring protrusion of the contraction joint tip.
