Detailed description of the invention
The utility model is made with reference to Fig. 1, Fig. 2, Fig. 3.This narrow space nut loading and unloading clamp, comprise handle 1 and cylindrical shell 2, the middle part of handle 1 is fixed on the upper end of cylindrical shell 2, and the axes normal of handle 1 and cylindrical shell 2, it is characterized in that: the end opening elasticity of described cylindrical shell 2 connects the outer inclined tab 3 of 3 equidistant arrangements, the lower end inner wall composition nut jaws of the outer inclined tab 3 of 3 equidistant arrangements, because the perisporium of nut is all made up of hexagon, so the nut jaws consisted of 3 outer inclined tab 3 can clamp the limit at 3 intervals of nut, it is made to accommodate power homogeneous; Be folding gap 4 between adjacent outer inclined tab 3, the width adjusting opened by folding gap 4, can clamp the nut of different size; The outer surface of 3 outer inclined tab 3 is cambered surface, the cross section of the outer surface of 3 outer inclined tab 3 is on same circular arc, cambered surface is provided with the screw thread 5 be connected, the sheathed oblique threaded screw 6 in the outside of 3 outer inclined tab 3, the internal thread gradient of oblique threaded screw 6 coordinates with the screw thread 5 of 3 outer inclined tab 3 outer surfaces, rotated by the screw thread 5 of oblique threaded screw 6 along 3 outer inclined tab 3 outer surfaces, the nut jaws that 3 outer inclined tab 3 can be made to form reduces, thus can binding nut; Otherwise, upwards rotated by the screw thread 5 of oblique threaded screw 6 along 3 outer inclined tab 3 outer surfaces, automatically open large under the reset response that the nut jaws that 3 outer inclined tab 3 can be made to form connects in elasticity, thus can loosen nut, or reconcile and clamp larger nut.
As improvement of the present utility model: the upper end of described oblique threaded screw 6 is provided with 4 connecting rods 7 of symmetric arrays, the upper end of 4 connecting rods 7 and the plane perpendicular of change 8 are fixed, change 8 is set in the upper end of cylindrical shell 2, by the rotation of change 8, the rotation of oblique threaded screw 6 can be driven, to be conducive to going deep into position rotating operation at narrow.
The upper end of the end opening of described cylindrical shell 2 and the outer inclined tab 3 of 3 equidistant arrangements connects as one, its connecting portion is stretch section, this elasticity is realized by processing technology process, the hypomere of outer inclined tab 3 does not possess bending elasticity, thus keep enough grip strength, that is, when strengthening clamping force or the torsion of clamping nut, the nut jaws of 3 outer inclined tab 3 compositions can not be out of shape, distortion.
The medial surface of described 3 outer inclined tab 3 is plane, the medial surface lower end of inclined tab 3 is provided with nut clamping limiting stand 9 outside, limit clamped nut by nut clamping limiting stand 9 and be in position in the nut jaws of 3 outer inclined tab 3 compositions, comparatively deep location in clamped nut can be prevented to be in nut jaws that 3 outer inclined tab 3 form, can prevent again the clamped nut when pressing rotation and installing from moving up, cause and install unsuccessfully, meanwhile, be also conducive to fast clamp nut.
The lower end of described oblique threaded screw 6 is provided with LED lamp bead 10, LED lamp bead 10 connects button cell 11 by wire, and button cell 11 is embedded in change 8, and its gauge tap 12 is located in change 8, when installing nut place insufficient light, LED lamp bead 10 can be opened and throw light on.
The overall diameter of described cylindrical shell 2 is 5-10mm, slightly larger than the overall diameter of the minimum nut that will clamp; The length of cylindrical shell 2 can be determined according to the degree of depth of narrow installation position.
When using the utility model, the nut that will install is placed on flat board, on the nut that what the nut jaws 3 outer inclined tab 3 of the present utility model formed again was vertical be enclosed within will install, rotate change 8, oblique threaded screw 6 is rotated, the nut jaws formed to 3 outer inclined tab 3 clamps the nut that will install, now can pick up the nut that will install, aim at the screw rod end of stenosis or narrow depths again, by turning handle 1, make the cap rotation that will install, the nut that will install can be arranged on the screw rod that will install, to tightening.
