Furthermore, a plurality of clamping blocks are arranged on the outer side wall of the column body below the convex part.
Furthermore, the edge of the opening at the front end of the through hole is chamfered.
Furthermore, the edge of the hole opening at the rear end of the through hole is chamfered.
Furthermore, a groove communicated with the front end orifices of the two through holes is formed in the front end face of the cylinder.
Further, the cross section of the cylinder is oblong.
Furthermore, the cylinder is made of nylon.
Further, the convex part is in a conical shape with a narrow front part and a wide back part.
Further, the convex part is in a conical shape with a wide front part and a narrow back part.
Furthermore, when the column body is inserted into the threading hole of the ball frame, the plane of the two through holes is vertical to the plane of the ball frame.
Further, the wall thickness of the through hole is 0.4 mm.
Compared with the prior art, the utility model discloses following beneficial effect has: this device is provided with the primary and secondary diplopore on a protective wire pipe, avoids the defect that exists in the original diplopore use, reduces tearing to the protective wire pipe, improves the protection dynamics of noble thread hole and net twine, and the threading also no longer need repeated via hole, and the longitude and latitude line is automatic staggers during the wiring simultaneously, no longer need stagger the longitude and latitude line like original diplopore hole wantonly, makes racket net twine overall arrangement reasonable more pleasing to the eye, simple structure, long service life.
In order to make the aforementioned and other objects, features and advantages of the invention more comprehensible, preferred embodiments accompanied with figures are described in detail below.
