Further, the supporting device includes baffles on both sides, and a chute is provided on the inside of the baffle, a support plate is provided between the two sets of chute, and a pulley is provided in the chute, and the pulley passes through the pin The shaft is rotatably connected with the support plate.

Further, there are four sets of positioning pins, and the area formed by the positioning pins is rectangular.

Further, a pull ring is installed in front of the support device.

Further, a through hole is provided above the cover plate.

Further, a circuit board positioning member is arranged on the support plate.

Further, a ring of strong magnetic strips surrounds the edge of the cover.

Further, a stopper is provided on the positioning pin, the stopper is arranged under the cover plate, and a spring is arranged between the stopper and the cover plate.

Compared with the prior art, the present invention has the following beneficial effects: the circuit board patch fixture can accurately position and install the circuit board through the design of the support plate; through the design of the chute and the pulley, the circuit board can be It is faster to install and take the board; through the design of the electromagnet and the cover plate, the circuit board can be fixed and controlled by the switch, which is more convenient and time-saving; through the design of the through hole, since the through hole is set above the welding position , which makes it easier to compare the position during welding; through the design of the spring, after the power is cut off, the cover plate can be bounced up, so that the support plate can slide out of the chute, and avoid bumping the circuit board. The circuit board patch fixture has the advantages of reasonable structural design, simple welding, etc., and at the same time, the design of the pulley makes the installation and taking of the circuit board easier and faster, and can be widely used.
