After the large-scale thick circuit board to be electroplated is fixed through the fixation clamp, the sliding slide tube is slid, the upper fixation plate descends, the circuit board descends along with the upper fixation plate, the bottom of the circuit board is placed on the support rod, the support plate is pushed to move through the spring to fix the bottom of the circuit board, the slide tube and the slide rod are fixed after the bottom of the circuit board is supported through the support rod, after the circuit board is fixed on the fixation clamp and the support rod, the circuit board is immersed into the electroplating bath for electroplating after the fixation block and the hoisting equipment are fixed, the circuit board to be electroplated can be fixed through the device, the electroplating fixation requirements of circuit boards with different sizes can be met, and the bottom of the circuit board is supported through the support rod, so that the circuit board is prevented from being damaged due to sliding from the fixation clamp when the circuit board moves.

Preferably, limiting blocks are fixed at the tail ends of the supporting rods.

Preferably, the fixing device comprises a threaded pipe fixed on the sliding pipe, and a threaded rod in threaded connection with the threaded pipe is arranged on the threaded pipe. When the sliding tube is fixed, the threaded rod is rotated, and the bottom of the threaded rod is extruded by the sliding rod to fix the sliding tube with the sliding rod due to the threaded connection of the threaded rod and the threaded tube.

Preferably, the lower fixing plate is also fixed with a limiting plate. Because the limiting plate is of a trapezoid structure, the supporting plate can be automatically pushed away by contacting with the limiting plate when the circuit board descends.

Compared with the prior art, the utility model has the following advantages:

the circuit board to be electroplated can be fixed through the device, the electroplating fixed requirements of circuit boards with different sizes can be met, the bottom of the circuit board is supported through the supporting rod, and the circuit board can be prevented from being damaged due to the fact that the circuit board slides from the fixing clamp when moving.
