Specifically, as Figure 3 shown, the third displacement mechanism includes a third air cylinder 23 installed on the second sliding seat, a guide block 24 connected to the second sliding seat, and a second guide rail 25 installed on the third sliding seat.

The third displacement mechanism is used to drive the fixed block 5 to descend, so that the first clamping groove 6 presses on the pipe fitting. At the same time, the vacuum generating device 10 evacuates the cavity 7 inside the fixed block 5 to generate negative pressure, so as to adsorb the pipe fitting through the first clamping groove 6. Then the third displacement mechanism drives the fixed block 5 to rise, so as to lift the pipe fitting. Then the first cylinder 14 extends to drive the clamping mechanism to descend until it reaches below the horizontal plane where the fixed block 5 is located. Then the fourth displacement mechanism is used to drive the clamping mechanism to move towards the pipe fitting and reach below the pipe fitting. Then the first cylinder 14 contracts to drive the clamping mechanism to rise, so as to clamp the pipe fitting. Thus, through the dual actions of adsorption and clamping, the pipe fitting is kept stable, and at the same time, the pipe fitting can be fully covered to prevent it from falling.
