Preferably, described first half-shell is provided with draw-in groove, and draw-in groove is arranged at the face of first half-shell and the second half-shell laminating, the Two half-shell are provided with and the projection of card slot fit.

Preferably, the inwall of described first half-shell is provided with two for shape between the pit housing hoodle, two pits Become to have the abutting ridge for preventing hoodle from upspringing.

Preferably, described connection assembly forms a hollow cylinder after including the fillet of screw, first half-shell and the second half-shell split, The fillet of screw is threadeded with hollow cylinder, and the fillet of screw is coaxially disposed with hollow cylinder.

Preferably, the described fillet of screw is connected with the threaded one end of hollow cylinder, and the fillet of screw is provided with two, two fillets of screw It is respectively arranged at the two ends of hollow cylinder.

Preferably, described first half-shell is provided with the first rib, and the first rib is arranged at first half-shell and the second half-shell patch The face closed, the first rib includes transverse part that the axis of rotation of bearing of trend and first half-shell is parallel to each other, bearing of trend and the The orthogonal longitudinal part of axis of rotation of one half-shell, the second half-shell is provided with the second rib being engaged with the first rib.

The beneficial effects of the utility model: a kind of expansion link regulation head of the present utility model, simple in construction, by the first half Shell, the second half-shell and connection assembling components form, and can realize lossless partition, be conveniently replaceable the hoodle within expansion link after partition, Avoid the occurrence of and give up the phenomenon of a whole piece expansion link because hoodle is impaired, reduce the use cost of expansion link.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in detail.

As shown in Fig. 1 ~ 4, a kind of expansion link regulation head of the present utility model, including first half-shell 1 He removably connected Second half-shell 2, also includes the connection assembly for first half-shell 1 and the second half-shell 2 being removably connected, first half-shell 1 and Two half-shell 2 split back walls set formation for the through hole wearing expansion link.A kind of expansion link regulation head of the present utility model, structure letter Single, first half-shell the 1, second half-shell 2 and connection assembling components form, lossless partition can be realized, be conveniently replaceable flexible after partition Hoodle within bar, it is to avoid occur giving up the phenomenon of a whole piece expansion link because hoodle is impaired, reduce expansion link Use cost.

Preferably, described first half-shell 1 is provided with draw-in groove 11, and draw-in groove 11 is arranged at first half-shell 1 and fits with the second half-shell 2 Face, the second half-shell 2 is provided with the projection 21 coordinated with draw-in groove 11.A kind of expansion link regulation head of the present utility model, during assembling, Draw-in groove 11 is plugged in protruding 21, it is to avoid first half-shell 1 misplaces with the second half-shell 2, it is simple to assembly and connection assembly, improves group Dress convenience, improves the stability that first half-shell 1 is connected with the second half-shell 2 simultaneously.

Preferably, the inwall of described first half-shell 1 be provided with two for the pit 12 housing hoodle, two pits 12 it Between be formed with the abutting ridge 13 for preventing hoodle from upspringing.One end of hoodle be connected to the first bar of expansion link and the second bar it Between, the other end of hoodle is connected to abut the ridge 13, it is to avoid the first bar and the second bar slide；Under press regulation of the present utility model During head, pit 12 is slipped into from abutting the ridge 13 in one end of hoodle, thus hoodle can be upspring between the first bar and the second bar, Jin Ershi Now stretch or shrink the function of expansion link.

Preferably, described connection assembly includes the fillet of screw 4, forms a hollow after first half-shell 1 and the second half-shell 2 split Body, the fillet of screw 4 threadeds with hollow cylinder, and the fillet of screw 4 is coaxially disposed with hollow cylinder.A kind of expansion link of the present utility model Regulation head, it is simple to dismounting, and stable connection.Further, the described fillet of screw 4 is connected with the threaded one end of hollow cylinder, screw thread Circle 4 is provided with two, and two fillets of screw 4 are respectively arranged at the two ends of hollow cylinder.

Described first half-shell 1 is provided with the first rib 14, and the first rib 14 is arranged at first half-shell 1 and pastes with the second half-shell 2 The face closed, the first rib 14 includes transverse part 141, the extension side that the axis of rotation of bearing of trend and first half-shell 1 is parallel to each other To longitudinal part 142 orthogonal with the axis of rotation of first half-shell 1, the second half-shell 2 is provided with and is engaged with the first rib 14 Second rib 22.After first rib 14 and the occlusion of the second rib 22, send after first half-shell 1 and the second half-shell 2 split can be avoided The horizontal and vertical changing of the relative positions, further increases assembling convenience.

Understanding this utility model in sum is to have above-described good characteristic, is made it on using, promotes The usefulness that do not has in conventional art and there is practicality, become the product of a great practical value.
