[0010] Preferably, in order to improve the clamping effect, the surface of the arc-shaped clamping groove and the outer arc surface of the arc-shaped pressing block are both wrapped with rubber pads.

[0011] Preferably, a guide rail is vertically fixed on the base plate corresponding to the first cylinder, a slider is slidably mounted on the guide rail, and the tailstock of the second cylinder is fixed on the slider.

[0012] By fixing the tailstock of the second cylinder on the slide block, the guide rail can support the second cylinder, thereby ensuring that the arc-shaped pressing block at the end of the second cylinder has a good pressing effect on the turbocharger housing.

[0013] Preferably, a protection rod is fixed on the second cylinder, a guide sleeve is fixed on the protection rod, and the piston rod of the second cylinder is movably arranged in the guide sleeve.

[0014] By adopting the above technical solution, the guide sleeve can provide guiding support for the piston rod of the second cylinder, reduce the influence of the clamping reaction force on the piston rod of the second cylinder, and thus increase the service life of the second cylinder.
