A channel is provided at the vertical center of the workbench. The channel is threadedly connected to a screw rod. Rectangular grooves are symmetrically provided on the upper and lower sides of the workbench. A second pull rod is placed on each of the left and right sides of the screw rod in each rectangular groove. The second pull rod is connected to the screw rod by a rope. The second pull rod is connected to a first pull rod. The first pull rod is connected to the clamping block.

[0006] Preferably, the first pull rod is provided with a number of first round holes, and the second pull rod is provided with a second round hole.

[0007] Preferably, the first round hole and the second round hole are the same size and are corresponding in the upper and lower positions.

[0008] Preferably, a bolt is provided in the second round hole.

[0009] The technical effect and advantage of the utility model: By using the provided bolt, first round holes and second round holes, the total lengths of the first pull rod and the second pull rod can be adjusted according to the size of the circuit board, so that the clamping block approaches the circuit board, and then the screw rod is rotated for clamping, reducing the number of turns of rotating the screw rod and improving the work efficiency.
