That is, the vertical plate 310 and the upper coupling part 333 press the vertical plate 310 and the upper coupling part 333 overlapped with each other laterally to press the center of the upper coupling part 333 and the vertical plate 310 in contact with it. ) part is fixed to each other by protruding and deforming the two vertical plates 310 inward, and the vertical plate 310 and the lower coupling part 334 are overlapped with each other by the vertical plate 310 and the lower coupling part 334. ) is pressed to the side, and the center of the lower coupling part 334 and a part of the vertical plate 310 in contact with it are fixed to each other by protruding and deforming the two vertical plates 310 inward.

According to the crossbar fixing part 300 configured as described above, the crossbar 100 is a front formed on the static support 330 in a state in which the front supporter 330 and the rear supporter 320 are installed on the two vertical plates 310 . It enters between the two vertical plates 310 through the insertion hole 331 and is inserted into the rear insertion hole 321 formed in the rear support body 320 .

At this time, the crossbar 100 is vertically angled about the rotational shaft 340 by the rotational shaft 340 installed to laterally penetrate the front ends of the two vertical plates 310 , the front support 330 and the crosspiece 100 . installed to be adjustable. And thus, between the rear insertion hole 321 and the crosspiece 100, a clearance in the vertical direction is provided so that the end of the crosspiece 100 inserted into the rear insertion hole 321 can flow up and down.

Here, the rotation shaft 340 may be formed of a hexagonal bolt that passes through the front ends of the two vertical plates 310 , the front support 330 and the crossbar 100 laterally and is fastened with a nut. And at this time, on the outside of the front end of any one of the two vertical plates 310 , the heads of hexagonal bolts extending along the vertical direction of the vertical plate 310 to form the rotation shaft 340 are installed from both sides, respectively. Two outer locking jaws 313 to support may be formed. The two outer locking projections 313 are in contact with both sides of the head of the hexagonal bolt constituting the rotation shaft 340 to support the rotation shaft 340 not to rotate, thereby facilitating the fastening of the nut when the rotation shaft 340 is assembled.

In addition, an upper female screw 325 and a lower female screw 326 respectively penetrating through the upper and lower surfaces of the rear body 322 are formed in the rear support 320 to communicate with the rear insertion hole 321, and the upper female screw The upper support bolt 350 and the lower support bolt 360 are respectively fastened to the 325 and the lower female screw 326 . At this time, the upper support bolt 350 and the lower support bolt 360 are fastened so as to be in contact with the upper and lower surfaces of the crossbar 100 fitted in the rear insertion hole 321 , respectively. Therefore, by rotating the upper support bolt 350 and the lower support bolt 360 to adjust the depth fastened to the upper female screw 325 and the lower female screw 326, respectively, by adjusting the vertical angle of the crosspiece 100, the crosspiece ( 100) can be fixed.

In addition, as shown, the crossbar fixing part 300 further includes a fixing pin 370 installed to laterally penetrate the rear end of the two vertical plates 310 , the rear support 320 and the crosspiece 100 . can The fixing pin 370 may be formed of a bolt that penetrates the rear end of the two vertical plates 310 , the rear support 320 , and the crossbar 100 and is fastened with a nut. In addition, a long hole 110 is formed at an end of the crosspiece 100 to be vertically elongated and into which the fixing pin 370 is inserted. According to the fixing pin 370 and the long hole 110 , the end of the crosspiece 100 fitted in the rear insertion hole 321 is fixed to be movable up and down, so that the crosspiece 100 can be more stably fixed.
