Embodiment
The present invention is more fully illustrated below with embodiment.The present invention can be presented as a variety of multi-forms,
It is not construed as the exemplary embodiment for being confined to describe here.
For ease of explanation, the space relative terms such as " on ", " under ", "left", "right" can be used herein, are used for
The element or feature shown in explanation figure is relative to another element or the relation of feature.It should be understood that except figure
In outside the orientation that shows, spatial terminology is intended to include the different azimuth of device in use or operation.If for example, in figure
Device be squeezed, be stated as being located at other elements or feature " under " element will be located into other elements or feature " on ".
Therefore, exemplary term " under " can be both comprising upper and lower orientation.Device can be positioned otherwise（It is rotated by 90 ° or position
In other orientation）, can correspondingly be explained used herein of the relative explanation in space.
Hydraulic vibration fishing device as shown in Figure 1 includes：The vibration recurring structure and the fisher 6 of bottom on top.
Vibration recurring structure includes：Main element 1, sliding block 2, sealing shroud 3, back-moving spring 4 and connector 5.Main element 1
Upper water inlet 1.1, upper pod apertures 1.2 and lower pod apertures 1.4 with pressure fluid, sliding block 2 are bottom-up by the envelope of water inlet 1.1
Stifled, sliding block 2 blocks upper pod apertures 1.2 while water inlet 1.1 are blocked, and pressure fluid promotes sliding block 2 to remove block-up position
Afterwards, water inlet 1.1 is realized with upper pod apertures 1.2 and turned on, and the lower section of sliding block 2 is provided with back-moving spring 4 and connector 5, back-moving spring 4
One end is acted against on sliding block 2, and the other end is acted against on connector 5, and balance is encircled into by sliding block 2, main element 1 and connector 5
