The side panels 2 are sleeved on both side surfaces of the circuit board body 1, and stabilizing blocks 3 are movably embedded on the upper surface of the side panels 2 near both ends. A pushing piece 4 is movably embedded inside the side panels 2, and a connecting rod 5 is fixedly installed on the front surface of the pushing piece 4.

The groove 202 is connected; the pushing member 4 includes a pull rod 401, a pull block 402, a stop ring 403, and a support block 404. The pull rod 401 passes through the stop groove 201 and the movable groove 202. The front end surface of the pull rod 401 is fixedly installed with the pull block 402, and the connecting rod 5 is fixed to the pull block 402; the surface of the pull rod 401 and the fixed sleeves near the two ends are provided with stop rings 403, and the surface of the pull rod 401 inside the movable groove 202 is fixedly installed with a support block 404, which can push the stabilizing block 3 upward; the upper end of the pull-down spring 206 is fixed to the sleeve block 301, and the lower end of the pull-down spring 206 is fixed to the inner lower surface of the lifting groove 204.
