[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the overall idea of ​​the technical solution in the embodiment of the present application is as follows:

[0023] In response to the problems existing in the prior art, the utility model provides a highly practical small bolt, including a bolt 1, a bolt rod 11 is fixedly installed below the bolt 1, a threaded groove 16 is opened above the bolt 1, two slots 15 are fixedly installed above the bolt 1 on both sides of the threaded groove 16, and a second bolt 14 can be installed above the bolt 1. The user can insert the first insertion rod 19 and the two second insertion rods 2 at the end of the bolt head 17 into the threaded groove 16 and the two slots 15 opened in the bolt 1, and then rotate the bolt head 17 with a screwdriver. The rotation of the bolt head 17 will drive the bolt 1 to rotate, so that the bolt 1 can be removed or installed. By designing the bolt 1 to be connected with multiple bolts 1 and the second bolt 14, a variety of installation methods can be achieved. A bolt head 17 can also be installed above the bolt 1.

[0024] A plug joint 13 is fixedly installed below the bolt rod 11. The end of the plug joint 13 is tapered. An annular groove 12 is provided on the outer ring of the lower end of the bolt rod 11 above the plug joint 13. The second bolt 14 has the same overall structure as the bolt 1. When the second bolt 14 is connected to the bolt 1, the bolt rod 11 at the lower end of the second bolt 14 is threadedly installed in the thread groove 16 opened in the bolt 1. The plug joint 13 is tapered and can enter the thread groove well. At the same time, the annular groove 12 is provided at the end of the bolt rod 11, which can make the plug joint 13 transition well with the bolt rod 11, which can facilitate the installation of the bolt 1. A cross groove 18 is provided above the bolt head 17. A first plug rod 19 is fixedly installed below the bolt head 17. Two second plug rods 2 are fixedly installed below the bolt head 17 on both sides of the first plug rod 19. An anti-slip pad 22 is fixedly installed on the upper end of the bolt 1. At least two stress grooves 23 are provided on the surface of the bolt rod 11, and at least two auxiliary cross grooves 21 are provided on the side wall of the bolt 1.

[0025] Working principle:

[0026] In the first step, when installing the bolt 1, the user can insert the plug connector 13 at the end of the bolt 1 into the threaded hole, rotate the bolt 1, and the bolt rod 11 at the end of the bolt 1 can be rotated and matched with the threaded hole. When the two plates are fixed horizontally and the second plate has no fixing point, the user can pass the bolt rod 11 at the end of the second bolt 14 through the plate and then insert the bolt rod 11 into the threaded groove 16 opened by the bolt 1. At this time, the second bolt 14 and the bolt 1 are fixed, and the plate is fixed by the bolt 1 and the second bolt 14. When the user encounters difficulty in removing the bolt 1 with a wrench, the user can insert the first insertion rod 19 and the two second insertion rods 2 at the end of the bolt head 17 into the threaded groove 16 and the two slots 15 opened in the bolt 1. When the bolt head 17 is rotated with a screwdriver, the rotation of the bolt head 17 will drive the bolt 1 to rotate, so that the bolt 1 can be removed or installed. By designing the bolt 1 to be connected with multiple bolts 1 and the second bolt 14, a variety of installation methods can be achieved. At the same time, the bolt head 17 can assist in the installation or removal of the bolt 1, changing the installation method, thereby improving the convenience of use.

[0027] In the second step, the plug connector 13 is tapered and can be well inserted into the thread groove. At the same time, the end of the bolt rod 11 is provided with an annular groove 12 to make the plug connector 13 transition well with the bolt rod 11, which can facilitate the installation of the bolt 1.

[0028] By providing auxiliary cross grooves 21 on the side walls of the bolt 1, the second bolt 14 and the bolt head 17, a cross tool can be inserted into the auxiliary cross groove 21 in some narrow spaces, and the cross tool can be directly rotated horizontally to complete the disassembly of the bolt 1, the second bolt 14 and the bolt head 17, which greatly improves the operability in a narrow space. At the same time, the stress groove 23 provided on the surface of the bolt rod 11 can help disperse the pressure on the bolt rod 11 during rotation, reduce the probability of the bolt rod 11 breaking, and improve the overall operability. The anti-slip pad 23 can improve the airtightness when the multiple bolts 1, the second bolt 14 and the bolt head 17 are connected, and improve the anti-slip ability.
