- 13 are arranged vertically, and the tips and bent portions of adjacent long pieces are prevented from coming off by E-rings 27.
5, the short piece 18 of the first L-shaped arm 11 is provided with a mounting bracket 16, which is a mounting part, and the table 17 is connected.
is fixed, the lamp 8 is provided at the tip of the long piece of the third L-shaped arm 13, and the first L-shaped arm 11 to the third L-shaped arm 13 are fixed.
The power supply wire 28 is passed through the L-shaped arm 13 of. A flexible resin pulley 21 is supported by a knurled screw 22 on the short pieces 18 to 20 of each L-shaped arm 11 to 13, the upper end of the wire 23 is attached to the upper end of the third arm 13, and the wire is passed through each pulley 21. , a coil spring 24 serving as a balancer is passed through the lower end, one end of the coil spring 24 is locked to the short piece 18, and a thumbscrew 25 is screwed into the threaded rod 26 connected to the lower end of the wire 23 to secure the other end of the spring 24. Support it and adjust the spring by tightening the thumbscrew 25.
