Detailed description of the invention
Below in conjunction with Figure of description, the technical solution of the utility model is described in further detail。
As shown in Figure 1, spring penetrating cable clamp moment nut twists into two parts the device that comes off, de-bar 1 is twisted including with moment nut matches, it is sheathed on the circular gripping sleeve 2 twisting de-bar 1 front portion, it is sheathed on the annular retaining ring 3 twisting de-bar 1 rear portion, twist the de-bar 1 position between gripping sleeve 2 and annular retaining ring 3 and be provided with spring 4, annular retaining ring is affixed with the stubborn de-bar 1 passing through central hole, the postmedian twisting de-bar 1 is straight circular cylinder type, the front portion twisting de-bar 1 is circular cone shape, frustum of a cone external diameter is pre-large post-small, perforation is sheathed on by axial center and twists de-bar 1 middle front part by gripping sleeve 2, the front end of perforation is provided with and the tapering twisting the anterior frustum of a cone laminating of de-bar 1 by the center of gripping sleeve 2, twist de-bar 1 be provided with the axial springhole 101 corresponding with moment nut and extend radially through the elastic groove 103 twisting de-bar 1, springhole 101, elastic groove 103 opening is forward, after spring 4 holds out against forward gripping sleeve 2, elastic groove 103 narrows with clamping torque nut, the rear portion twisting de-bar 1 is provided with opening electric tool interface holes 106 backward。
