[0022] Please refer to Figs. 1-2 The utility model provides a technical scheme: a cassette nut with positioning structure, including nut 1, the middle part of nut 1 is equipped with screw hole 11, nut 1 sets up in cassette shell, the bottom of cassette shell is equipped with bottom plate 12, both sides of bottom plate 12 are fixedly installed with side plate 13, both groups of side plate 13 top are fixedly installed with buckle 14, the elastic support mechanism is installed between bottom plate 12 and nut 1, both sides of elastic support mechanism correspond to both groups of side plate 13 respectively, and elastic support mechanism includes the support plate 2 of nut 1 bottom adhesion installation, the elastic piece 21 of both sides fixed installation of support plate 2, both groups of elastic piece 21 bottom are mutually adhesion with bottom plate 12.

[0023] When cassette nut is not used, nut 1 will be supported by the two groups of elastic pieces 21 at the bottom of support plate 2, and the top of nut 1 is pressed against the bottom of the two buckles 14, which can position nut 1 and prevent it from shaking in the cassette shell. At the same time, as the bolt is threadedly connected with the screw hole 11, the nut 1 in the cassette shell can move towards the workpiece along the direction of the bolt. As the bolt is continuously screwed with the nut 1, the support plate 2 on the bottom side of the nut 1 can be pressed, and the elastic pieces 21 on both sides of the support plate 2 can be continuously extended outward. After the two groups of elastic pieces 21 on the outside are in contact with the two groups of side plates 13, the elastic pieces 21 can be expanded to the maximum value. In combination with the two groups of elastic pieces 21, the nut 1 on the top of the support plate 2 can be supported in the opposite direction, effectively fixing the nut 1 in the cassette shell, increasing the stability and firmness of the nut 1 and the bolt, and preventing the nut 1 from loosening and falling in the cassette shell.

[0024] In this technical scheme, support blocks 3 are welded and installed at both ends of both sides of the bottom plate 12, and the four groups of support blocks 3 correspond to the bottom of the nut 1, which can limit the bottom of the nut 1. Two groups of anti-falling blocks 31 are welded on both sides of the two side plates 13, and the four groups of anti-falling blocks 31 correspond to the top of the nut 1, which can limit the top of the nut 1.

[0025] When the nut 1 is distributed inside the cassette shell, in combination with the support blocks 3 distributed at the four corners of the bottom of the nut 1 and the anti-falling blocks 31 distributed at the four corners of the top of the nut 1, the nut 1 can be supported inside the cassette shell, preventing the cassette nut from falling from the cassette shell when subjected to strong jolts, and ensuring the completeness of the cassette nut.

[0026] In this technical scheme, through holes 22 are formed in the middle of the bottom plate 12 and the support plate 2, and the two groups of through holes 22 correspond to the screw hole 11, which can be connected with the bolt.

[0027] By aligning one of the clamping nuts 14 with one side of the mounting hole and gently pushing it in with your hand or a tool, ensure that both sets of clamping nuts 14 are clamped on the edge of the mounting hole, so that the clamping nut is firmly installed in the mounting hole, and the bottom plate 12 and the through hole 22 in the middle of the support plate 2 can be aligned with the bolt and nut 1 in the middle of the nut 1, and twisted together.

[0028] In use, first align one of the clamping nuts 14 with one side of the mounting hole and gently push it in with your hand or a tool, ensure that both sets of clamping nuts 14 are clamped on the edge of the mounting hole, so that the clamping nut is firmly installed in the mounting hole, and the bolt and nut 1 in the middle of the nut 1 can be aligned and twisted together, as the bolt and the threaded hole 11 are connected, the nut 1 in the clamping shell can move towards the workpiece along the direction of the bolt, as the bolt and the nut 1 are twisted together, the support plate 2 on the bottom side of the nut 1 can be extruded, the elastic members 21 on both sides of the support plate 2 can be continuously expanded outward, after the two sets of elastic members 21 on the outside are in contact with the two sets of side plates 13, the elastic members 21 can be expanded to the maximum value, and the two sets of elastic members 21 can support the nut 1 on the top of the support plate 2 in the opposite direction, effectively fixing the nut 1 in the clamping shell, increasing the stability and firmness of the nut 1 and the bolt, avoiding the nut 1 from falling off in the clamping shell, on the contrary, when the clamping nut is not in use, the nut 1 will be supported by the two sets of elastic members 21 on the bottom of the support plate 2, and the nut 1 on the top and the two sets of clamping nuts 14 on the bottom will be in contact, which can position the nut 1 and avoid the nut 1 from shaking in the clamping shell, at the same time, the support blocks 3 are welded and installed on both sides of the bottom plate 12, and the anti-falling blocks 31 are welded on both sides of the two sets of side plates 13, when the nut 1 is distributed inside the clamping shell, the support blocks 3 distributed at the four corners on the bottom of the nut 1 and the anti-falling blocks 31 distributed at the four corners on the top of the nut 1 can support the nut 1 inside the clamping shell, avoiding the nut 1 from falling off from the clamping shell when the clamping nut is subjected to strong vibration, ensuring the completion of the clamping nut.
