Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated portable portable ultrasonic probe supporting structure of the present utility model.
As shown in Figure 2, portable portable ultrasonic probe supporting structure of the present utility model be in original portable portable ultrasonic probe supporting structure, pop one's head in 2 ' the basis on probe bracket is installed.This probe bracket includes the probe that is connected with ultraoscilloscope, this probe bracket also includes shell body 6, in shell body 6, be with inner housing 7, at shell body 6, inner housing 7 corresponding down either side are respectively equipped with perforation, the perforation of inner housing 7 is a threaded hole, forcing screw 4 inserts from two side perforations of shell body 6, and be screwed into successively respectively and be located at shell body 6, the holding nut 5 between the inner housing 7 and the threaded hole of inner housing 7, at shell body 6, the top center place of inner housing 7 is provided with perforation respectively, adjust screw 1 and at first be screwed into nut 2, insert shell body 6 then successively, the overp0unch of inner housing 7, between the overp0unch of shell body 6 and inner housing 7, be provided with spring 3, described probe 9 is fixed on the end of adjusting screw 1, and four jiaos of places are provided with roller 8 respectively in shell body 6 bottoms.
