The circuit board placement structure includes a number of circuit board brackets 4 that are overlapped in sequence from bottom to top, and the circuit board brackets are vertically slid on the side of the support column. When in use, the circuit board brackets 5 filled with circuit handles are overlapped in sequence and slid and fixed on the support column, so that the circuit board brackets can be detached, and additional manual arrangement is required, thereby improving production efficiency.

[0023] In this embodiment, in order to realize that the circuit board bracket can be used to install the circuit board, the circuit board bracket includes a support plate 6, and a plurality of transverse partitions 7 are arranged on the support plate at intervals along the width direction. The transverse partitions divide the support plate into a plurality of mounting grooves 8, and the circuit boards are placed in the mounting grooves at intervals, that is, the support plate is divided into a plurality of mounting grooves by the transverse partitions to realize the orderly arrangement of the circuit boards. More specifically, in order to realize the fixation of the circuit board: a plurality of limiting rubber blocks 9 are arranged in the mounting grooves at intervals along the length direction, and the limiting rubber blocks in each mounting groove correspond to each other one by one. Several limit rods 10 are provided in the partition, and the transverse partition is perpendicular to the limit rod. The limit rod is installed on the transverse partition, and the limit rod corresponds one-to-one to the limit rubber block in the same mounting groove. The limit rod is located directly above the corresponding rubber block, that is, when in use, the circuit board is tilted in the mounting groove, the tilted lower end of the circuit board abuts against the side of the limit rubber block, and the tilted upper end of the circuit board abuts against the limit rod on the limit rubber block on the side, so as to realize the placement of the circuit board. At the same time, by setting the spacing between the limit rubber blocks and the spacing between the limit rods, the device can adapt to circuit boards of various lengths.

[0024] In this embodiment, in order to specifically realize the adjustable spacing between the limit rods, a number of clearance installation grooves 11 are provided on the transverse partitions corresponding to the limit rods. The clearance installation grooves on each transverse partition correspond to each other one by one, and the limit rods are clamped in the corresponding clearance installation grooves, that is, the limit rods can be installed in the clearance installation grooves with different intervals, so that the spacing between the limit rods can be adjusted.

That is, when the upper and lower circuit board brackets are overlapped, it is necessary to cooperate with the ladder-shaped slide groove on the support column and the ladder-shaped slider on the support plate to slide to achieve stability.

[0028] In this embodiment, in order to enable the overlapped circuit board bracket group to slide as needed, the sliding base includes a sliding support plate 19, a sliding armrest 20 is provided on the rear side of the sliding support plate, and existing walking wheels 21 with brakes are installed under the four corners of the sliding base.
