Circumferential one end of equal semicircular in shape, the small end is connected to the big end by interconnecting piece；
The circumferential other end of the small end forms small flange portion, and the other end of the big end circumferential direction is formed with big method
Blue portion, described small its thickness direction of flange portion upper edge offer left through-hole, and the large flange portion its thickness direction of upper edge offers
Right through-hole, left screw pass through the left through-hole of the left through-hole and lower link portion in the upper connecting rod portion, right screw to pass through the upper connecting rod
The right through-hole in portion and the right through-hole in lower link portion, the upper connecting rod portion and lower link portion are fixed together.
Optionally, middle through-hole is offered on the interconnecting piece, middle screw passes through the middle through-hole in the upper connecting rod portion and lower company
The upper connecting rod portion and lower link portion are fixed together by the middle through-hole of bar portion.
Optionally, upper edge its width direction in the upper connecting rod portion is formed with multiple strips protrusion, in the lower link portion
It is formed with the groove of the multiple strip protrusion of correspondence, when the upper connecting rod portion and lower link portion are fixed together, to grow
Strip bulge is located in the groove.
The present invention has the advantages that：The connecting rod of the present invention, by the way that connecting rod is divided into upper connecting rod portion and lower link portion,
And upper connecting rod portion and lower link portion are fixed together by screw so that the present invention connecting rod can bear it is larger
Pulling force needs the occasion for bearing pulling force suitable for connecting rod.
