A lifting connecting rod assembly 6 for adjusting the height of the workbench 1 is also provided between the support columns 2. The lifting connecting rod assembly 6 is provided in two groups, which are respectively located between the two support columns 2 on the front side and between the two support columns 2 on the rear side.

[0030] like Figure 2 and Figure 3 As shown, the lifting link assembly 6 includes a guide rod 63 fixed between the left and right support columns 2, the left end of the guide rod 63 is fixed to the right side of the left support column 2, and the right end of the guide rod 63 is fixed to the left side of the right support column 2. A bidirectional threaded rod 61 is arranged above the guide rod 63, the left end of the bidirectional threaded rod 61 is rotatably connected to the right side of the left support column 2, and the right end of the bidirectional threaded rod 61 is rotatably connected to the left side of the right support column 2. A sliding block 62 is respectively sleeved in two intervals with opposite thread directions on the bidirectional threaded rod 61, and the two sliding blocks 62 move in opposite directions when the bidirectional threaded rod 61 rotates. A sliding sleeve 66 is transversely arranged at the lower part of each sliding block 62, and the guide rod 63 runs through the sliding sleeve 66 to realize the sliding connection between the sliding block 62 and the guide rod 63. A transmission strip plate 64 is hinged on the top of each sliding block 62, and a fixed block 65 is hinged on the other end of the transmission strip plate 64, and the fixed block 65 is fixed to the bottom of the workbench 1.

[0031] The lifting link assembly 6 located between the two front support columns 2 is also provided with a driving device. The driving device is specifically a hand wheel 5 arranged at the right end of the front two-way threaded rod 61, the driving end (right end) of the two-way threaded rod 61 passes through the support column 2 on the right side thereof, and the hand wheel 5 is located outside the support column 2.

[0035] The utility model discloses a device for clamping an experimental circuit board, and its use method is as follows:

[0036] The experimenter holds the crank 4 and turns the hand wheel 5 according to his own height, so that the bidirectional threaded rod 61 starts to rotate, driving the two sliding blocks 62 on the bidirectional threaded rod 61 to start to move in the opposite direction, so that the transmission strip 64 rotates with the sliding block 62 as the axis, driving the height of the fixed block 65 to change synchronously. At the same time, the rotation of the bidirectional threaded rod 61 drives the pulley 71 to start rotating, and under the action of the transmission belt 72, the pulley 71 on the other side also rotates synchronously, driving the entire lifting link assembly 6 on the rear side to move synchronously with the lifting link assembly 6 on the front side. In this way, the height of the workbench 1 is adjusted longitudinally, driving the top of the guide column 9 in the support column 2 to move synchronously in the up and down directions.

[0038] After the experiment is completed, the screw 83 is loosened and the circuit board is taken out from the clamping plate 82. The crank 4 is held again to rotate the hand wheel 5 in the opposite direction to restore the workbench 1 to its original height.
