Cheng Kaiguan 12, there is circuit connection between travel switch 12 and motor 54 and electronic reel 44.When fixed block 801 moves up
And when touching the travel switch 12 of top, travel switch 12 controls electronic reel 44 to close, and now pupil has lifted
To peak, it is impossible to continue to rise, ensure that the safety of pupil and the stabilization of whole device, when fixed block 801 is to moving down
When moving and touching the travel switch 12 of lower section, electronic reel 44 and motor 54 simultaneously close off, and now pupil can be from stepping on
Get off on plate 7, eliminate the trouble of manual control.
Because also including valve 13, aqueduct 85 is provided with valve 13.Valve 13 can enter to the water-carrying capacity of aqueduct 85
Row control, can more preferably maintain stabilization of the pupil in raising and lowering.
Embodiment described above only expresses the preferred embodiment of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, some deformations can also be made, improves and substitutes, these belong to this hair
Bright protection domain.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
