[0027] See also Figure 1 , a bolt comprises a nut part 1 and a screw part 2.

[0028] The nut portion 1 is in the shape of a regular polygon, and accordingly, the nut portion 1 has a plurality of planar outer walls 1 a having the same number as the sides of the regular polygon.

[0029] Optionally, the nut portion 1 has four sides or six sides.

[0030] The first end of the screw part 2 is integrally connected to the nut part 1, and the second end of the screw part 2 is provided with a slot 2a. As for the two third ends of the slot 2a, both can penetrate the arc outer wall of the screw part 2, or both can not penetrate the arc outer wall of the screw part 2, or one of them can penetrate the arc outer wall of the screw part 2.

[0031] In this way, the bolt and nut are used together on the workpiece. When tightening or loosening is needed, the bolt can be turned by acting on the nut part 1 with a corresponding wrench, or by acting in the slot 2a with a corresponding flat-blade screwdriver.

[0032] The nut part 1 and the slot 2a are located on both sides of the workpiece, respectively. The wrench needs space in the radial direction of the bolt when it matches the nut part 1, and the slotted screwdriver needs space in the axial direction of the bolt when it matches the slot 2a. Therefore, such a bolt and nut match can be applied to some occasions with certain space restrictions. By selecting a suitable rotation method, the bolt can be tightened or loosened very simply and conveniently.

[0033] See also Figure 4Optionally, the screw portion 2 includes a threaded section 2b and a smooth section 2c, which corresponds to the above description of "the first end of the screw portion 2 is integrally connected to the nut portion 1", and is as follows: one end of the threaded section 2b is integrally connected to the screw portion 2, and the smooth section 2c is integrally connected to the other end of the threaded section 2b. The arc outer wall of the threaded section 2b has external threads, while the arc outer wall of the smooth section 2c does not have external threads, and the smooth section 2c is truncated cone-shaped, that is, the diameter of the end connected to the threaded section 2b is larger. The smooth section 2c is provided so that there can be a certain transition when the screw portion 2 is initially matched with the nut, which facilitates the screw portion 2 to enter the nut at the beginning.

[0034] It can be found that if the two third ends of the slot 2a penetrate the arc outer wall of the screw part 2, then there will be a defect 2e in the external thread at that position. When the screw part 2 is first matched with the nut, due to the defect 2e of the external thread, it is easy to have an unsmooth match, and the screw part 2 is not easy to screw into the nut.

[0035] Combined with the above-mentioned setting that "the screw portion 2 includes a threaded section 2b and a smooth section 2c", further, the depth of the slot 2a only passes through a portion of the smooth section 2c.

[0036] In this way, by utilizing the arrangement of the smooth section 2c and arranging the slot 2a on the smooth section 2c, even if the third end penetrates the arc outer wall of the screw portion 2, the threaded section 2b will not have the above-mentioned defective portion 2e of the external thread. This can also avoid the situation that the screw portion 2 and the nut do not fit smoothly at the beginning.

[0037] In addition, after the bolt is processed by thread rolling to complete the external thread, the slot 2a is processed, and the slot 2a is set on the smooth section 2c, which makes the processing of the slot 2a more convenient and labor-saving.

[0038] See also Figure 1 , Figure 2 and Figure 3 Optionally, the two third ends of the slot 2a penetrate the arc outer wall of the screw portion 2, and at least one of the multiple planar outer walls 1a is parallel to the slot 2a. If the nut portion 1 is four-sided or six-sided, two planar outer walls 1a are parallel to the slot 2a.

[0039] Matched to the corresponding first placement part 3, specifically, the cross section of the first placement part 3 is L-shaped, and the vertical part is provided with a horizontal first insertion strip 3a. When the bolt is placed, it can be horizontal, and the slot 2a is inserted into the first insertion strip 3a; the plane outer wall 1a parallel to the slot 2a just fits the horizontal part of the first placement part 3.

[0040] If an ordinary bolt is placed vertically with the nut part 1 at the bottom, it is easy to fall over. Therefore, ordinary bolts are generally placed horizontally, and accordingly, the second end of the screw part 2 will contact the placement plane and tilt, and the plane outer wall 1a will only contact the placement plane at the edge close to the screw part 2. It can be seen that ordinary bolts are not stable enough when placed in this way, and it is also easy to wear the external thread of the screw part 2 that contacts the placement plane, affecting the matching between the screw part 2 and the nut. With the help of the straight groove 2a, which is matched with the first placement part 3, the bolt can be placed very stably, and this design can also be applied to the packaging box of bolts.

[0041] See also Figure 5 and Figure 6 Optionally, the two third ends of the slot 2a penetrate the arc outer wall of the screw portion 2, and the two third ends also correspond to the middle positions of the two planar outer walls 1a respectively.

[0042] Matched to the corresponding second placement part 4, specifically, the cross section of the second placement part 4 is L-shaped, and the vertical part is provided with a vertical first insertion strip 3a. When the bolt is placed, it can be horizontal, the slot 2a is inserted into the second insertion strip 4a, and the inner wall of the slot 2a is pressed against the second insertion strip 4a from the axial direction of the bolt; through the two plane outer walls 1a corresponding to the slot 2a, the bolts are stacked in sequence on the horizontal part of the second placement part 4.

[0043] Similarly, by means of the slot 2a, which is matched with the second placement portion 4, the bolt can be placed very stably. This design can also be applied to the packaging box of the bolt.

[0044] See also Figure 7 In addition, it can be found that when the nut portion 1 has four sides, both the first placement portion 3 and the second placement portion 4 can be used.
