DETAILED DESCRIPTION
[0023] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0024] like Figure 1 and Figure 6 As shown, the cutting head structure of the tile cutting machine of this embodiment at least includes a guide rail 1, on which a cutting head 100 is slidably connected, and a cutter wheel 101 is connected to the bottom of the cutting head 100. The cutting head 100 includes a head front shell assembly 3, a handle 6, and left and right shell assemblies 2 located at the front end of the handle 6 and rotatably connected to the head front shell assembly 3. The head front shell assembly 3 is slidably connected to the guide rail 1, and an elastic reset member is provided between the head front shell assembly 3 and the left and right shell assemblies 2, and the cutter wheel 101 is provided at the bottom of the left and right shell assemblies 2. The elastic reset member of this embodiment is preferably a torsion spring 4.
[0025] like Figure 2 As shown, grooves 11 are respectively provided on the left and right sides of the guide rail 1 , and the groove 11 is provided with an upper inclined surface 12 and a lower inclined surface 13 .
[0026] like Figure 5 As shown, the torsion spring 4 includes a spiral body 41 and a first torsion arm 42 and a second torsion arm 43 extending from two sides of the spiral body 41 .
[0027] like Figure 3 As shown, the left and right housing components 2 are provided with a first torque arm hole 21 adapted to the first torque arm 42 and a first receiving groove 22 for receiving the spiral body 41 .
[0028] like Figure 4As shown, the front housing assembly 3 of the machine head is provided with a second torque arm hole 31 adapted to the second torque arm 43 and a second receiving groove 32 for accommodating the spiral body 41, and a bearing mounting hole 33 for mounting a bearing is also provided in the second receiving groove 32.
[0029] like Figure 6 As shown, the spiral body 41 of the torsion spring 4 is installed in the first receiving groove 22 and the second receiving groove 32. The second torsion arm 43 is installed in the second torsion arm hole 31 and is fixed. The first torsion arm 42 is installed in the first torsion arm hole 21 and rotates with the movement of the left and right housing components 2.

The front housing assembly 3 of the machine head is provided with a second screw 35, the nut of the second screw 35 is located outside the front housing assembly 3 of the machine head, and a rubber member 36 is arranged between the threaded end of the second screw 35 and the adjustment block 34.
[0032] When it is necessary to adjust the contact tightness between the lower bearing 37 and the lower inclined surface 13, it is only necessary to rotate the nut part of the second screw 35 exposed outside the front shell assembly 3 of the machine head to drive the adjustment block 34 to move closer to or away from the lower inclined surface 13, thereby adjusting the contact tightness between the lower bearing 37 and the lower inclined surface 13, which is convenient and quick.
[0033] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
