The ratio between radius of three gear 213c is 2:1:2.When the rack gear 212 drives first gear 213a to turn around, second tooth
Wheel 213b also rotates a circle, since the second gear 213b is meshed with the third gear 213c, the third tooth at this time
213c rotation is taken turns less than a circle.Assuming that needing one circle of first gear 213a rotation can be by institute when second, third gear 213c is not added
Grip block 2111 is stated to open to 90 °；After it joined second, third gear 213c, then one circle of first gear 213a rotation, described
The angle that grip block 2111 is opened is less than 90 °.At the same time, longer before the length ratio that the elastic component 214 stretches, thus
The tensile elongation of elastic component 214 is increased, so that the elastic restoring force that elastic component 214 gives rack gear 212 is increased, so that two folders
The dynamics for holding the clamping capture apparatus of plate 2111 is stronger, and then increases the clamping stability of clamping device 10.
Herein it should be noted that, between the setting quantity and several gears 213 of said gear 213 radius relationship as just
Citing, it is of course possible to which more than three gears 213 are set, and the size of third gear 213c and first gear 213 can not phase
Deng specific setting can be according to the size of the substrate 21, and required chucking power etc. is comprehensive to be designed.Also, it is above-mentioned
Enumerating the embodiment that three gears match not is exclusive embodiment, any mutual cooperation by big pinion gear, to change
