[0027] On one side of the base 1, a guiding bracket 7 is vertically fixed. On the front side of the guiding bracket 7, two slide rails 71 are vertically fixed. The lifting bracket 6 is slidably connected to the corresponding slide rail 71 through a slider 72. The lifting bracket 6 can reciprocate vertically relative to the guiding bracket 7.

[0028] On the back side of the guiding bracket 7, there are a first lateral bracket 73 and a second lateral bracket 74. Two first guiding shafts 75 are horizontally installed on the first lateral bracket 73. One end of the first guiding shaft 75 is rotatably installed with a first guiding wheel 76.

The lifting bracket 6 slides linearly upward along the two slide rails 71, and the guiding frame 21 moves linearly upward relative to the first guide wheel 76 and the second guide wheel 78. When the outlet height of the spring bar supply device needs to be decreased, the driving motor 3 drives in reverse, the driving wheel 31 drives the driven wheel, the intermediate shaft 41, the worm wheel, and the worm 52 to rotate. The worm 52 rotates in reverse and moves downward relative to the base 1. The lifting bracket 6 and the outlet end of the entire supply device descend. The transmission shaft 63 moves within the first strip-shaped frame 61 and the second strip-shaped frame 62. The lifting bracket 6 slides linearly downward along the two slide rails 71, and the guiding frame 21 moves linearly downward relative to the first guide wheel 76 and the second guide wheel 78.
