[0031] The working principle and use process of the utility model: when the exhaust gas recirculation valve is assembled and fixed, the fixing mechanism body 100 is first placed on the assembly production line through the bottom plate 101 and fixedly installed. Therefore, when the fixing mechanism body 100 is fixedly assembled to the recirculation valve, the position of the clamping plate 1021 is adjusted according to the model of the recirculation valve, and the hand wheel 1023 can be held to drive the threaded rod 1022 to rotate. When the threaded rod 1022 rotates, the adjustment connecting block 1024 is moved, and the two clamping plates 1021 are adjusted to match the clamping arc of the recirculation valve surface by moving the adjustment connecting block 1024, and the clamping plate 1021 is adjusted to match the clamping arc of the recirculation valve surface.

The bidirectional screw rod 105 rotates to move the two moving heads 104 toward each other at the ends of the bidirectional screw rod 105. The movement of the moving head 104 drives the vertical plate 102 and the clamping plate 1021 to move until the clamping plate 1021 is moved, clamped and fixed on the surface of the recirculation valve, and the fixing mechanism body 100 is convenient for the fixed installation and assembly operation of the recirculation valve.

[0033] Finally, when the fixing mechanism body 100 is clamped and fixed, the moving head 104 moves on the outer surface of the two-way screw rod 105 to drive the vertical plate 102 to move, and at the same time, the uniform force support frame 1012 moves on the outer surface of the two-way screw rod 105 at the same speed as the moving head 104, and the uniform force support frame 1012 is supported on the side ends of the vertical plate 102 by the moving head 2 1011 when moving, so as to support the force on both sides of the vertical plate 102 during the tight installation, and the vertical plate 102 is not easily deformed or unstable by external force when the vertical plate 102 is clamped and fixed. The two sides of the vertical plate 102 are uniformly clamped and fixed for installation, which improves the uniform force clamping and fixing effect of the fixing mechanism body 100 on both sides of the vertical plate 102 when the recycling valve is clamped and fixed, and is convenient for better clamping and fixing assembly.
