[0037] It should be noted that, in order to reduce the working strength of personnel and improve safety, an automatic pushing structure can be installed on one side of the top of the workbench 1. A cylinder can be used to cooperate with a push plate. The push plate is installed on the driving end of the cylinder. Then the cylinder is installed on the top of the workbench 1. When the cylinder is opened, the driving end of the cylinder is elongated to drive the push plate to move the heat-conducting gasket, so that the automatic pushing effect is realized. Since the cylinder and the push plate are prior art, they will not be described in detail in the specification.

[0038] In addition, if it is necessary to cut the heat-conducting gasket in different positions, the electric push rod 17 and the driving end thereof can be slidingly arranged on the top of the L-shaped plate 2 to drive the protective cover 3 to adjust the position. Then, the electric push rod 17 which has completed the sliding is positioned by cooperating with the positioning structure. The heat-conducting gasket in different positions can be conveniently cut. Since the electric push rod 17 is not required to slide according to the background technology, and this technology is also a mature technology, it will not be described in detail in the specification.

[0039] Working principle: in use, first, the heat-conducting gasket is placed on the top of the workbench 1. Then, the electric push rod 17 is turned on, the driving end of the electric push rod 17 is elongated to drive the protective cover 3 to move downward and abut against the heat-conducting gasket. Then, the heat-conducting gasket is cut by the blade 4. Then, the electric push rod 17 is continuously turned on, and the blade 4 is lowered into the fixed groove 18. At this time, the rollers 6 abut against the top of the heat-conducting gasket. Since the two rollers 6 are located on both sides of the blade 4 and are close to each other, the rollers 6 can limit the position of the blade 4 when the blade 4 cuts the heat-conducting gasket. Since the rollers 6 can roll on the surface of the heat-conducting gasket when the heat-conducting gasket is pushed, the heat-conducting gasket can be continuously positioned without repositioning.

[0040] In addition, when the cutting of the heat-conducting gasket with different thicknesses is needed, the motor 13 is started to rotate the threaded rod 11, so that the nut 12 drives the connecting rod 10 and the sliding block 8 to slide up and down along the direction in which the guide rail 7 is arranged, that is, the height of the roller 6 is adjusted, so that the cutting of the heat-conducting gasket with different heights can be adapted, and the problems of the suspension of the roller 6 or the motion interference are avoided.
