In order to solve the technical problems, the utility model adopts a technical scheme that: the utility model provides a appurtenance is prevented changeing in installation of core top screw, this appurtenance is prevented changeing in installation of core top screw includes handle, fixed nut thimble assembly and movable nut thimble assembly, handle upper portion is provided with circular mounting hole and rectangular type waist type hole, and fixed nut thimble assembly is installed to circular mounting hole department, and movable nut thimble assembly is installed to rectangular type waist type hole department, fixed nut thimble assembly includes nut sleeve, gasket and locking screw, the nut sleeve is the tubulose, nut sleeve axial is provided with installation screw hole and core nut dodges the hole, and locking screw passes behind gasket and the handle lock and attaches in the installation screw hole.
Preferably, the upper portion of the nut sleeve is provided with an anti-rotation boss which is long, and the bottom surface of the handle is provided with an anti-rotation sliding groove matched with the anti-rotation boss.
Preferably, the structure of the movable nut sleeve assembly is the same as that of the fixed nut sleeve assembly, and the distance between the movable nut sleeve assembly and the fixed nut sleeve assembly can be adjusted, so that the movable nut sleeve assembly is suitable for top structures of cores with different diameters.
Preferably, the handle afterbody extension design has handheld portion, utilizes lever principle, can easily block the core top.
Compared with the prior art, the utility model has the beneficial effects that:
design benefit can cooperate the spanner to use, blocks the core, keeps the core not to take place to twist reverse, and nut sleeve pipe position is adjustable, is applicable to different diameter core top structural installation, avoids producing the core distortion at core assembling process, reduces the human cost, improves the packaging efficiency.
