The internal structure can ensure the sealing during connection by setting the sealing matching groove, and by setting the guide connection groove, it can ensure that the operation of the center position structure during installation and fitting is more convenient. After the installation groove is fastened as a whole, it can be associated and combined with other mechanical components at a later time. It has greater flexibility in use and occupies less space as a whole.

[0004] The technical solution of the utility model is as follows:

[0005] The cam is secured to a location where the cam is secured to a position where the cam is in contact with the outer surface of the cam, and the cam has a central locking mechanism which allows the cam to be locked without interfering with the movement of the cam.

[0006] Furthermore, a side surface of the outer side of the fastening and fitting installation groove away from the central axis of the main body fastening combination column is a cylindrical structural surface and coincides with the cylindrical surface of the sealing combination fitting groove.

[0007] Furthermore, the fastening fitting groove intersects with the central fitting connection hole.

[0008] Beneficial effects of the utility model:

[0009] The utility model is used for overall fastening combination through the built-in installation groove and the fastening tool during fastening. Its center position can be matched with the mechanical component, and the overall fastening connection is performed through the outer threaded groove. The internal structure can ensure the sealing during connection by arranging the sealing matching groove, and the guide connection groove can ensure that the operation of the center position structure during installation is more convenient. After the installation groove is fastened as a whole, it can be associated with other mechanical components at a later time, which has greater flexibility during use and smaller overall space occupied.

[0018] like Figures 1 to 7As shown, an embedded fastening nut includes a cylindrical main body fastening combination column 1, the upper end of the main body fastening combination column 1 is provided with an integrally formed mating stable connecting seat 2, and the outer cylindrical surface of the main body fastening combination column 1 is provided with an integral fastening thread groove 3, through which the connection combination of the mechanical components is performed when fastening and mating. The outer side of the mating stable connecting seat 2 is a cylindrical structural surface, which makes the outer side have a smaller volume. A mating guide connecting groove 4 is respectively provided at the upper end center position of the mating stable connecting seat 2 and the lower end center position of the main body fastening combination column 1, to ensure that the center position structure has more space for installation and mating, and the assembly operation is more convenient. A conical avoidance combination guide groove 5 is provided at the lower end position of the upper end mating guide connecting groove 4, which has a reliable avoidance function and at the same time has a guiding function when placing the clamping tool when mating. A sealing combination matching groove is provided between the upper end of the avoidance combination guide groove 5 and the matching guide connection groove 4, which can be more tightly combined with the sealing ring when it is matched with the mechanical component in the later stage after tightening, so that the matching stability of the sealing ring is better, and the connection sealing during the combination is guaranteed to be better. The lower end of the avoidance combination guide groove 5 is provided with a cylindrical center matching connection hole 6 that is in communication with the avoidance combination guide groove 5 at the lower end, which can be stably matched with the mechanical structure in the later stage, and can achieve the installation matching effect of double matching inside and outside. The upper end position of the avoidance combination guide groove 5 is provided with a fastening matching installation groove 7 that is evenly distributed around the circumference, which can be matched with the tool during tightening to perform the fastening operation at the outer fastening position, and ensure that the operation during tightening is more stable. The fastening matching installation groove 7 does not penetrate the lower end surface of the main fastening combination column 1, and ensures better tightness of the center position during the later matching. When tightening, it is combined with the fastening tool through the embedded installation groove to perform the overall fastening combination. Its center position can be matched with the mechanical components, and the overall fastening connection is performed through the outer threaded groove. The internal structure can ensure the sealing during connection by setting the sealing matching groove, and by setting the guide connection groove, it can ensure that the center position structure is more convenient to operate during installation and matching. After the installation groove is tightened as a whole, it can be associated and combined with other mechanical components at a later time. It is more flexible in use and occupies less space overall.

[0019] Preferably, the outer side of the fastening fitting installation groove 7 away from the central axis of the main body fastening combination column 1 is a cylindrical structural surface and coincides with the cylindrical surface of the sealing combination fitting groove, so that the overall structural support strength is better, the service life during use is longer, and the combination stability during fitting is better.

[0020] Preferably, the fastening fitting installation groove 7 intersects with the central fitting connection hole 6, which provides better fitting security and stronger bearing capacity when the clamping tool is used for fastening operations.

[0021] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
