The specific embodiment:

Preferred embodiment of this utility model is: referring to Fig. 1, Fig. 2 and Fig. 4, this endoscope detecting automatic intervention device, the endoscope 1 that includes housing 2 and pass through housing 2, housing 2 upper fixed are settled dc motor 8 and endoscope's propulsive mechanism 15 of inner chamber arrangement dc motor 8 drivings, and move distance testing agency of endoscope 14 is settled on housing 2 right sides.The structure of above-mentioned endoscope's propulsive mechanism 15 is: the two pairs of synchronizing jugged

belt wheels

3,10,19,21 in front and back mesh former and later two waists of suit respectively just as step profile of tooth band 11,20, and former and later two constitute clamp mechanism with profile of tooth band 11,20 clamping endoscopies 1; Dc motor 8 stretches into pinion 7 of fixed installation on the output shaft in the housing 2, this pinion 7 and gear wheel 6 engagements, gear wheel 6 with last to a profile of tooth belt wheel 3 coaxial installations in the synchronizing jugged

belt wheel

3,10, a gear 26 engagements of installing in the rotating shaft of a profile of tooth belt wheel 19 of this middle part fixed installation gear 4 and a pair of synchronizing jugged belt wheel 19,21 in back constitute speed adjusting gear.

Referring to Fig. 3, housing 2 constitutes by two halves cavity 23,25 is involutory, joining realization by four pins 24 that are fixed in preceding half cavity 23 with the pin-and-hole cunning of later half cavity 25 is connected, before synchronizing jugged

belt wheel

3,10 is installed in preceding half cavity 23, then synchronizing jugged belt wheel 19,21 is installed in the later half cavity 25, the screw mandrel 17 of an outer end band handle 16 passes later half cavity 25 and spins with preceding half cavity 23, and screw mandrel 17 constitutes clamp mechanism at spring 22 of later half cavity 25 inner chamber section suits.
