Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

Please refer to fig. 1-4. It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions under which the present invention can be implemented, so that the present invention has no technical significance, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

The first embodiment is as follows:

a multi-purpose bolt comprises a bolt body and a connecting block detachably connected with the bolt body,

wherein the bolt body comprises a head 1 and a screw rod 2, the screw rod 2 is provided with a thread 3 for connecting to other components, meanwhile, in the embodiment, the connecting block is a square 6,

the head part 1 is of a circular structure, and the head part 1 is connected with a square block 6 through a connecting mechanism.

In this embodiment, the head 1 includes a connecting portion 4 connected to the screw rod 2 and a protrusion 5 protruding from the connecting portion 4, the surface area of the connecting portion 4 is larger than the surface area of the screw rod 2, the surface area of the protrusion 5 is equal to the surface area of the screw rod 2, and the connecting portion 4 is provided with a plurality of threaded holes 9,

a through hole 8 is arranged in the middle of the square 6, the surface area of the through hole 8 is equal to that of the convex part 5, so that the square 6 is just clamped outside the convex part 5 and is blocked by the connecting part 4,
