Cylindrical nail body structures are respectively arranged on both side surfaces of a connecting plate, so that two objects to be butted can be connected.

[0004] However, the sizes of the nail bodies on both sides of its connecting plate are the same, resulting in problems of more manufacturing consumables, high manufacturing cost, and inability to be disassembled and separated. Summary of the Utility Model

[0005] In view of the problems pointed out in the background art, the utility model provides a double-headed screw to solve the above technical problems.

[0006] The technical solution of the utility model is realized as follows:

[0007] A double-headed screw includes a first nail head and a first nail rod. The first nail rod is connected to one side surface of the first nail head, and two second screws are arranged on the other side surface of the first nail head.

[0008] The utility model is further arranged such that the second screw includes a second nail head and a second nail rod, and the second nail rod is connected to one side surface of the second nail head.

[0009] The utility model is further arranged such that the second nail head is fixedly welded to the first nail head.

[0010] The utility model is further arranged such that a connection hole corresponding to the second nail rod is provided on the first nail head, and the second nail rod is connected to the connection hole.

[0011] The utility model is further arranged such that the connection hole penetrates through both sides of the first nail head.

[0012] The utility model is further arranged to further include an annular gasket. The gasket is sleeved on the first nail rod, and the second nail head is located between the gasket and the first nail head.

[0013] The utility model is further arranged such that the gasket and the first nail rod are detachably connected.

[0014] The utility model is further configured such that the gasket is fixedly connected to the first nail rod, the distance between the gasket and the first nail head is greater than or equal to the thickness of the second nail head, a slot is provided at the edge of the first nail head, the slot is communicated with the connection hole, and the width of the slot is smaller than the diameter of the second nail rod.

[0015] By adopting the above technical solutions, the beneficial effects of the utility model are as follows:

[0016] (1) The second screw is small in size, so that the consumables for manufacturing the double-headed screw are less, achieving the purpose of reducing the manufacturing cost.

[0017] (2) The second screw is detachably arranged, making the use of the double-headed screw more convenient and more applicable. Description of the Drawings
