[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] The following describes an embodiment of the present invention based on its overall structure.

[0020] See also Figure 1-4A cable for machine tools includes a main conductor 1, an outer layer of the main conductor 1 is provided with an insulating layer 2, an outer layer of the insulating layer 2 is provided with a guiding conductor 3, an outer layer of the guiding conductor 3 is provided with a metal sleeve 4, the main conductor 1 is tightly fitted with the insulating layer 2, and the guiding conductors 3 are distributed in a ring array with the main conductor 1. In the device, one main conductor 1 and multiple guiding conductors 3 can maintain the smooth use of the entire cable and the stability of the power supply when the machine tool is used. The outer layer of the metal sleeve 4 is provided with an oxygen-insulating and fire-resistant layer 5, which is made of a calcium silicate board material, and the outer wall of the oxygen-insulating and fire-resistant layer 5 is provided with a metal copper mesh. The outer layer of the oxygen-isolating and fire-resistant layer 5 installed in the middle is covered with a metal copper mesh, which can better maintain the connection of the oxygen-isolating and fire-resistant layer 5, and at the same time improve the oxygen-isolating and fire-resistant and high-temperature resistant effects of the entire cable during use. The outer layer of the oxygen-isolating and fire-resistant layer 5 is covered with an outer sheath 6, and a fixing hole 7 is opened on the surface of the outer sheath 6. The limit frame 11 is made of insulating rubber material for the outer sheath 6, and the outer sheath 6 is a "cross" structure design. The outer end of the "cross"-shaped outer sheath 6 installed in the device is provided with a fixing hole 7, which can be used to place and fix the cable in different positions during use, thereby improving the safety of cable use.

[0021] Working principle: When in use, the cable is fixed or hung in different positions through the fixing holes 7 opened on the surface of the cross-shaped outer sheath 6 at the outermost end of the cable, which can maintain the diversity of cable use positions and at the same time maintain the safety of cable use. When the cable is in use, the oxygen-isolating and fire-resistant layer 5 in the device is made of calcium silicate board material, so that the entire machine tool cable can improve the oxygen isolation and high temperature resistance when used in the workshop, which can improve the safety of cable use and make the cable safer and more convenient when used on the machine tool.
