     Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. 
     In addition, it is clarified in advance that the panel below has a plate shape of a certain thickness, and the material of the panel may include any one of wood, cardboard, and synthetic resin materials. 
       FIG. 1  is a perspective view illustrating a panel cutting jig according to an embodiment of the present disclosure.  FIG. 2  is an exploded perspective view illustrating a panel cutting jig according to an embodiment of the present disclosure. 
     As illustrated in  FIGS. 1 to 2 , the panel cutting jig according to an embodiment of the present disclosure includes a main body  100  and a holder  200 . Overall, the main body  100  serves to accommodate the panel  10 , and the holder  200  applies elastic force to press the panel  10  inserted into the main body  100 , thereby serving to fix the panel inserted into the main body  100  to the main body  100 . Accordingly, a user can cut the panel  10  while the panel  10  inserted into the main body  100  is fixed by the elastic force of the holder  200 . The cutting of the panel  10  may be made with an electric saw or a manual saw. 
     The main body  100  is formed with an insertion channel  130  into which the panel  10  is inserted. This main body  100  may be formed in a rectangular frame shape as a whole. A cutting guide  102  formed perpendicular to the length direction of the main body  100  and guiding the cutting of the panel  10  inserted into the insertion channel  130  may be provided at one end of the main body  100 . In addition, the other end of the main body  100  may be provided with a panel insertion hole  101  formed to be inclined in a length direction of the main body  100  to guide the insertion into the insertion channel  130  of the panel  10 . 
     The material of the main body  100  is not particularly limited, but may be formed of, for example, High Density Polyethylene (HDPE). 
     The main body  100  may be separated into a first body  110  covering one side of the insertion channel  130  and a second body  120  covering the other side of the insertion panel. Specifically, the first body  110  and the second body  120  are stacked side by side, and in this way, the insertion channel  130  may be formed between the stacked first body  110  and the second body  120 . 
     Furthermore, the first body  110  and the second body  120  may be coupled to each other in a separable manner. 
     For example, as a fixing hole  112  is formed in one side of the first body  110  and a fixing protrusion  122  inserted into the fixing hole  112  is formed in one side of the second body  120 . Accordingly, one side of the first body  110  and one side of the second body  120  may be detachably coupled. The fixing hole  112  may be formed in a plate shape, and the fixing protrusion  122  may be formed in a hook shape. Accordingly, after the fixing protrusion  122  is inserted into the fixing hole  112 , the fixing projection  122  may be locked and fixed in the fixing hole  112  by the hook shape of the fixing projection  122 . 
     In addition, as a support wall  113  is formed in the other side of the first body  110  and the bearing wall  123  borne by the support wall  113  is formed in the other side of the second body  120 , the other side of the first body  110  and the other side of the second body  120  may be detachably coupled in a manner such that the support wall  113  is borne by the bearing wall  123 . The support wall  113  may be vertically bent and extended from the other edge of the first body  110 , and the bearing wall  123  may be vertically bent and extended from the other edge of the second body  120 . 
     Moreover, a locking projection  114  may be formed on the support wall  113 , and a locking hole  124  through which the locking protrusion  114  may be locked and fixed may be formed on the bearing wall  123 . Accordingly, when the support wall  113  is borne by the bearing wall  123 , as the locking protrusion  114  of the support wall  113  is locked and fixed to the locking hole  124  of the support wall  123 , the support wall  113  and the bearing wall  123  may be prevented from being separated. 
     A scale may be marked in at least one side of the first body  110  and the second body  120  in a length direction of the main body  100 . When scales are displayed in each of one side of the first body  110  and in one side of the second body  120 , the scales displayed in one side of the first body  110  and the scales displayed in one side of the second body  120  may be displayed in each different unit. For example, a scale marked in one side of the first body  110  may be displayed in centimeter units, and a scale marked in one side of the second body  120  may be displayed in inches. 
     A stepped unit  140  may be formed in one side of the first body  110  and one side of the second body  120 . Accordingly, a user may check and display the cut dimensions and cut portions of the panel  10  while the panel  10  is stably mounted on the stepped unit  140 . 
     A first opening  111  in which the holder  200  is disposed may be formed in any one of the first body  110  and the second body  120 , and a second opening  121  facing the holder  200  may be formed in the other of the first body  110  and the second body  120 . The first opening  111  may be formed in a plate shape, and the second opening  121  may be formed in a circular shape. The holder  200  penetrates into the insertion channel  130  between the first body  110  and the second body  120 . Accordingly, when the panel  10  is inserted into the insertion channel  130 , interference may occur between the holder  200  and the panel  10 . Therefore, before the panel  10  is inserted into the insertion channel  130 , it is preferred that force for discharging the holder  200  from the insertion channel  130  through the second opening  121  is applied to discharge the holder  200  from the insertion channel  130 . As such, when the holder  200  is discharged from the insertion channel  130 , it is possible to prevent interference between the holder  200  and the panel  10  from occurring when the panel  10  is inserted into the insertion channel  130 . 
     The holder  200  is elastically deformable and supports the main body  100 , and elastic force is generated toward the insertion channel  130 . In addition, the holder  200  applies elastic force to press the panel  10  inserted into the insertion channel  130 . The holder  200  may be supported on the inner surface of the first opening  111  of the first body  110 . 
     One end of the holder  200  may be provided with a stress dispersion unit  210  that is supports the main body  100  and is formed in parallel with the insertion channel  130  to disperse the stress caused by the elastic deformation of the holder  200 . For example, the stress dispersion unit  210  may be formed in the form of a plate parallel to the insertion channel  130 , and serves to prevent the holder  200  from breaking by dispersing stress due to elastic deformation of the holder  200 . 
     There is provided a holder separation unit  220  capable of applying force for discharging the holder  200  from the insertion channel  130  while the holder  200  applies elastic force to the panel  10  inserted into the insertion channel  130  to the other end of the holder  200 . For example, the holder separation unit  220  may be formed in a plate shape bent in a direction spaced apart from the insertion channel  130 . Accordingly, in a state in which the holder  200  applies elastic force to the panel  10  inserted into the insertion channel  130 , a user puts a hand between the holder separation unit  220  and the panel  10  so as to apply the force to discharge the holder  200  from the insertion channel  130 , so that the state in which the holder  200  applies the elastic force to the panel  10  may be released. 
     The holder main body  230  between the stress dispersion unit  210  and the holder separation unit  220  may have a pair of bending plates, and the bent portions of the pair of bending plates are in contact with the panel  10  to apply elastic force. 
     Hereinafter, an operation example of the present disclosure will be described. 
       FIGS. 3 to 7  are operational views of the panel cutting jig according to an embodiment of the present disclosure. 
     Referring back to  FIG. 1 , the holder  200  is bent toward the insertion channel  130  of the main body  100  to penetrate the insertion channel  130  of the main body  100 . Accordingly, only when the holder  200  is discharged from the insertion channel  130  of the main body  100 , it is possible to prevent interference between the holder  200  and the panel  10  when the panel  10  is inserted into the insertion channel  130  of the main body  100 . 
     Accordingly, as illustrated in  FIG. 3 , first, a user applies force for discharging the holder  200  from the insertion channel  130  of the main body  100  through the second opening  121  to discharge the holder  200  from the insertion channel  130  of the main body  100 . 
     Next, the user inserts the panel  10  into the insertion channel  130  of the main body  100  while maintaining the state in which the holder  200  is discharged from the insertion channel  130  of the main body  100 . The panel  10  may be easily inserted through the panel insertion hole  101  of the main body  100 . Thereafter, when the panel  10  reaches the holder  200  while being continuously inserted into the insertion channel  130 , the user releases the state in which the holder  200  is discharged from the insertion channel  130  of the main body  100 . As a result, the holder  200  may apply elastic force to press the panel  10  inserted into the insertion channel  130 . 
     Next, the user completely passes the panel  10  through the insertion channel  130  to dispose the cut portion of the panel  10  on the cutting guide  102  of the main body  100 . 
     Next, as illustrated in  FIGS. 4 to 5 , as the holder  200  applies elastic force to press the panel  10  inserted into the insertion channel  130 , the panel  10  inserted into the insertion channel  130  is fixed. The user may cut the panel  10  based on the cutting portion of the panel  10  disposed on the cutting guide  102  of the main body  100  using a cutting mechanism  20 . The user additionally applies pressing force to the main body  100  or the holder  200  while disposing the main body  100  into which the panel  10  is inserted on a workbench  30  to firmly fix the panel  10 . After fixing, the cutting portion of the panel  10  may be cut. A stationery knife, a chainsaw, and a hacksaw may be used as the cutting mechanism  20 . 
     Next, as illustrated in  FIGS. 6 to 7 , after the user turns over the main body  100 , the panel  10  may be cut based on the cutting portion of the panel  10  disposed on the cutting guide  102  of the main body  100 . The user additionally applies pressing force to the main body  100  or the holder  200  while disposing the main body  100  into which the panel  10  is inserted on the workbench  30  to firmly fix the panel  10 . After fixing, the cutting portion of the panel  10  may be cut. 
     Next, the user applies force for discharging the holder  200  from the insertion channel  130  through the holder separation unit  220  to discharge the holder  200  from the insertion channel  130  and release the elastic force applied to a wooden channel by the holder  200 . 
     Finally, the user discharges the panel  10  from the insertion channel  130 . 
     Accordingly, according to the present disclosure, the panel cutting jig according to an embodiment of the present disclosure has the advantage of stably fixing and cutting the panel  10  and making the cutting surface of the panel  10  even. 
       FIG. 8  is a perspective view illustrating a panel cutting jig according to another embodiment of the present disclosure. 
     As illustrated in  FIG. 8 , the panel cutting jig according to another embodiment of the present disclosure may further include a surface roughness adjustment unit  300  that may change the surface roughness of the cutting portion of the panel  10 , unlike the panel cutting jig according to an embodiment of the present disclosure. 
     The surface roughness adjustment unit  300  may be sandpaper provided on an outer surface of the main body  100 , and a user may change the surface roughness of the cutting portion of the panel  10  by using the sandpaper. 
       FIG. 9  is another operational view of the panel cutting jig according to an embodiment of the present disclosure. 
     As illustrated in  FIG. 9 , a user may cut the panel  10  using the cutting mechanism  20  based on the cutting portion of the panel  10  disposed in the panel insertion hole  101  of the main body  100 . Since the panel insertion hole  101  is an inclined surface, the cutting portion of the panel  10  may be formed as an inclined surface. 
     The panel cutting jig according to the present disclosure may be applied to cutting a plate having a predetermined thickness, and a panel for blind curtains. 
     Hereinbefore, the present disclosure has been described with reference to the embodiments shown in the accompanying drawings. It will be understood by those skilled in the technical field to which the present disclosure pertains that the present disclosure may be embodied in various other specific forms without departing from the technical ideas or essential characteristics of the present disclosure. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive perspective in all aspects.
