[0012] Preferably, two movable grooves are provided in the middle of the top of the base, and the two movable grooves are slidably connected to the two movable blocks respectively. The two movable grooves and the two movable blocks are matched to facilitate the stable movement of the two clamping bars.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] The first cylinder pushes the fixed block downward, thereby driving the test probe and the abutment ring to move downward synchronously. The abutment ring will first contact the PC motherboard, and as the fixed block continues to move downward, the two support rods will retract into the two mounting sleeves until the test probe contacts the PC motherboard.
