Description

Technical Field

[0001] The utility model belongs to the technical field of high-precision cutting, and in particular relates to a high-precision cutting device for a hidden bottom rail. Background Art

[0002] Hidden support rails are a common engineering structure design principle, commonly used in furniture, mechanical equipment and other fields. Its design concept is to hide the rails inside the structure so that they will not be exposed during daily use, thereby maintaining the overall beauty and simplicity. The working principle of hidden support rails mainly relies on the friction between the slider and the guide rail. Applying a certain amount of lubricant on the guide rail at the bottom of the slider can reduce the friction during sliding, thereby making the sliding smoother. In addition, the design of the slide rail also needs to take into account the stability and load-bearing capacity of the structure to ensure that no accidents occur during use.

[0003] The prior art discloses a high-precision cutting device with a patent announcement number of CN218476073U. The above patent uses an operating adjustment mechanism to enable the cutting motor to drive the mounting shaft to drive the cutting blade to rotate and make cuts. By comparing the screw mounting activity with the scale position, the movement amount is more accurate, thereby improving the cutting accuracy. However, in actual use, the following shortcomings still exist: when the device is operated, the operation is more labor-intensive and involves more manual work, which poses a greater safety hazard, and the height of the cutting blade cannot be adjusted.

[0004] Therefore, a high-precision cutting device with a hidden bottom rail is needed to solve the problems in the prior art that the operation of the device is labor-intensive, involves a lot of manual work, poses a major safety hazard, and cannot adjust the height of the cutting blade.
