Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily.
It should be clear that structure, ratio, size etc. depicted in this specification institute attached drawing, only to cooperate specification to be taken off
The content shown is not intended to limit the invention enforceable qualifications so that those skilled in the art understands and reads, therefore
Do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the present invention
Under the effect of can be generated and the purpose that can reach, the model that disclosed technology contents can be covered should all be still fallen in
In enclosing.Meanwhile cited such as "upper" in this specification, "lower", "left", "right", " centre " and " one " term, be also only
Convenient for being illustrated for narration, rather than to limit the scope of the invention, relativeness is altered or modified, in no essence
It changes under technology contents, when being also considered as the enforceable scope of the present invention.
As shown in Figure 1, the present invention provides a kind of telescoping cylinder piston rod thread spanner, comprising:
Handle 1, handle 1 have a first end and a second end in the longitudinal direction；
Hook 2 is held, the arc-shaped plate of hook 2 is held, hook 2 is held and has a first end and a second end in a circumferential direction, hold
The first end of hook 2 is connect with the first end of handle 1, holds the radius of curvature r of 2 internal perisporium of hook and the radius of flexible cylinder piston rod 4
It is adapted；
Make to hold hook 2 and the circumferentially fixed holding screw 3 of flexible cylinder piston rod 4, holding screw 3 is along the radial direction for holding hook 2
Screw thread is threaded through in the second end for holding hook 2.
In the present invention, the space as locating for flexible cylinder piston rod 4 is very narrow (for example, locating for end trimming shears oil cylinder
Space is very long and narrow, can not clamp the piston rod of end trimming shears oil cylinder, with conventional pipe wrench to fasten piston rod and other zero
Helicitic texture between part), it holds the arc-shaped plate of hook 2 and 3 screw thread of holding screw is threaded through in the second end for holding hook 2,
So that the overall dimensions for holding hook 2 are small and exquisite, staff can will hold hook 2 deeply to space locating for flexible cylinder piston rod 4
It is interior and by holding screw 3 that gripping hook 2 is circumferentially fixed on flexible cylinder piston rod 4, in this way, swing handle 1 can make to stretch
