Specific embodiment

The utility model embodiment is described further referring to figs. 1 to Fig. 2.

A kind of screw, including rivet nut, the rivet nut includes rotary fixed head 401 and rotating handles 101, the rotating handles 101 oval in shape, the rotary fixed head 401 is cylindrical, the longest diameter of the rotating handles 101 and rotary fixed head The ratio of 401 diameters is the ratio 2.9- of 4.5-4.7, the most short diameter of the rotating handles 101 and the diameter of rotary fixed head 401 3.1, boss 201 is additionally provided with the rotating handles 101, the both sides of the boss 201 are provided with support block 301, the support Block 301 and the integrally connected of boss 201, the rectangular triangle in the section of the support block 301, the He of the rotary fixed head 401 Connector is provided between rotating handles 101, the connector includes contiguous block 501 and scattered power block 601, the contiguous block 501 1 End and one end integrally connected of scattered power block 601, the contiguous block 501 is cylindrical, and the scattered power block 601 is described to dissipate in round table-like The diameter of the minimum end face of power block 601 is identical with the diameter of rotary fixed head 401, the scattered other end of power block 601 and rotary fixed head 401。

By adopting above-mentioned technical proposal, rotary fixed head 401 and rotating handles 101, rotating handles are included by rivet nut 101 oval in shape, the rotary fixed head 401 is cylindrical, the longest diameter of the rotating handles 101 and rotary fixed head The ratio of 401 diameters is 4.5-4.7, is less than with the ratio of the diameter of rotary fixed head 401 by the longest diameter of rotating handles 101 When 4.5, rotary fixed head 401 is placed in center, causes the both sides finger of rotary fixed head 401 to be not easy to place, and is not easy to rotation, rotation The longest diameter of handle hand 101 is more than 4.7 with the ratio of the diameter of rotary fixed head 401, is easily caused extension too greatly, is not easy to place Screw, the ratio of the longest diameter of rotating handles 101 and the diameter of rotary fixed head 401 can be good at using when 4.6, Two fingers are respectively placed on one side to be screwed, and thumb is put on rotating handles 101 carries out three finger rotations, protects The ratio 2.9-3.1 of the convenience of card rotation, the most short diameter of the rotating handles 101 and the diameter of rotary fixed head 401, by this The setting of sample, can enable handle end face sufficiently large, and the placement for being easy to thumb is had an effect, consequently facilitating rotation, using rotation Boss 201 is additionally provided with handle hand 101, the intensity of rotating handles 101 is improved, the both sides of the boss 201 are provided with support block 301, it is supported in both sides by support block 301, the supported on both sides of boss 201 is strengthened, so as to ensure bulk strength, support Block 301 and the integrally connected of boss 201, the further intensity for ensureing connection, the rectangular triangle in the section of the support block 301 Shape, the intensity and holding strength of its own, the rotary fixed head 401 and rotation handle are ensured using the stability of triangle Be provided with connector between hand 101, the connector includes contiguous block 501 and scattered power block 601, the one end of the contiguous block 501 with dissipate One end integrally connected of power block 601, the contiguous block 501 is cylindrical, and the scattered power block 601 is in round table-like, the scattered power block 601 The diameter of minimum end face is identical with the diameter of rotary fixed head 401, the scattered other end of power block 601 and rotary fixed head 401, utilizes Contiguous block 501 serves connection reinforcement, and by round table-like scattered power block 601, it is inclined-plane to dissipate the side of power block 601, works as finger Firmly rotation produces shearing force, carries out oblique transmission by inclined side and offsets and consumption, it is ensured that the shearing force of transmission subtracts It is few, so as to ensure bearing capacity, so as to improve overall bearing strength.
