Detailed Description

The present invention will be described in further detail with reference to the following specific examples, which should not be construed as limiting the invention.

As shown in fig. 1, the present embodiment provides a PCB fixing device, which includes a PCB chute baffle 1 disposed on a working platform 7, a PCB baffle 2, a moving bracket 3 configured to slide in the PCB chute baffle 1, and a fixing component 4 configured to abut against the moving bracket 3.

The PCB chute baffle 1 and the PCB baffle 2 are connected to form an L shape.

The side wall of the PCB baffle 2 is provided with a groove 21 for clamping the side edge of the PCB.

Referring to fig. 2, a chute 11 for sliding the movable support 3 is formed in the bottom of the PCB chute baffle 1, a sliding block 31 is arranged at the top of the movable support 3, the sliding block 31 is welded to the movable support 3, the sliding block 31 is located in the chute 11 and abuts against the chute 11, the cross sections of the chute 11 and the sliding block 31 are in an inverted T shape, and the sliding block is prevented from falling out of the chute; the bottom of the mobile bracket 3 abuts against the fixed component 4.
