Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Example 1:

referring to fig. 1-8, a tow hook device with cone protection threads comprises a connection fork 5, a connection pin 7 for fixing is arranged on the connection fork 5, the connection fork 5 is fixedly connected with one end of a connection pipe 4, the other end of the connection pipe 4 is fixedly connected with a fixing portion 9, the fixing portion 9 comprises a transition section 901, a conical section 902 and a stud section 903, the transition section 901, the conical section 902 and the stud section 903 are sequentially arranged, the transition section 901 is fixedly connected with the connection pipe 4, and the fixing portion 9 is connected with a pipe sleeve 1 fixed on a frame through the stud section 903. The pipe sleeve 1 is fixed on the frame through a mounting plate 2. The mounting plate 2 is provided with a plurality of mounting holes 3. Two mounting holes 3 are respectively arranged on two sides of the mounting plate 2. The connecting fork 5 is U-shaped. The connecting fork 5 is provided with a first connecting hole 6, the first connecting hole 6 is provided with a connecting pin 7, and the connecting pin 7 is provided with a limiting pin 8 for limiting the axial movement of the connecting pin 7.
