Further, a buffer spring is arranged between the upper part 61 and the lower part 62 to prevent misjudgment caused by small vibration.
Wherein, in this embodiment, have pressure sensor in the hinge driver 2 to control left hinge 3, with the clamping force of right hinge 4 in reasonable within range, can not the clamping force not be enough, also can not the clamping force too high. And in addition, corresponding rubber buffer pads are arranged on the positions of the left hinge 3 and the right hinge 4 corresponding to the clamped burette.
the device provided by the embodiment of the present invention has the same implementation principle and technical effect as those of the embodiment 1, and for the sake of brief description, reference may be made to the corresponding contents in the embodiment 1 without reference to the embodiment.
In this embodiment, the difference from embodiment 1 is that the touch sensor of embodiment 1 is replaced by an infrared sensor 7, and the infrared sensor 7 is disposed on a surface of the hinge actuator 2 away from the frame body 1. An infrared sensor 7 is used to sense whether the burette is near the clamping area of the hinge actuator 2.
Further, for protecting infrared inductor 7 from being worn, hinge driver 2 is equipped with recess 8 corresponding to the one side of infrared inductor 7, infrared inductor 7 is located in recess 8.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
