The present invention relates to a chan- nel cutting apparatus characterized by a cutting module that can optimize various types of chan- nels for their respective forms to facilitate cutting quickly.

Instead of using hanger or separate furniture to make the interior clean and beautiful at a clothing or shoe store, a channel is attached to the wall, and a shelf and a shelf are installed in the groove of the channel to display various clothes and shoes to attract the attention of the guests . In addition, many households can use chanel as a bookcase or a shelf to minimize the space occupied by furniture, thus providing a spacious and comfortable living space.

In order to use the chanel, it needs to be cut to a proper length according to the height of the inside of the building. The chanel is produced in a long length and the shape and size of the channel are different for each manufacturer. Therefore, there has been a great deal of difficulty in providing or manufacturing a cutter dedicated to the channel, which is quick and easy to cut the channel to an appropriate length at the worksite.

For this reason, high speed cutters and hacksaws are mainly used for cutting channels in the field, and when using a high speed cutter, the working time is saved and a large number of channels can be cut at a time. However, when cutting a channel made of metal with a high-speed cutter, the cut surfaces were not uniform, and some parts were squashed. In addition, pollution and noise occurred during cutting, and the operator was exposed to the cutting blade at the cutting blade of the cutting machine, and metal debris and dust generated at the cutting occurred, resulting in various safety and health problems for the operator.

In order to solve such a problem, as a conventional technique, there has been proposed a duct-dedicated cutting apparatus which can easily cut a wiring duct to a desired length.

For example, in Patent Publication No. 10-0966103 (Registration Date: Jun. 17, 2010), through holes (hereinafter referred to as " holes " 21) are formed in the duct cutting apparatus (10). However, it is impossible to insert all the ducts according to the manufacturing characteristics of each manufacturer into the cutting unit 20, so that cutting is not possible. In addition, the cutting unit 20, in which the duct cutting device 10 and the duct 30 are located, is integrated so that when a part is worn out or broken, only the failed part can not be replaced, There are difficulties such as.
