The power cylinder of this embodiment adopts a cylinder 1, and the power cylinder of other embodiments can adopt a hydraulic cylinder, etc. The upper end surface of the support 3 is installed with a slide rail 5, and the slide rail 5 is slidably connected with the slider 4. The slider 4 is closely connected with the suspension rubber positioning block 8 through the connecting seat 7 to ensure that the suspension rubber positioning block 8 can move with the movement of the slider 4. A limit block 6 is set at the other end of the support 3, and the limit block 6 can limit the maximum stroke of the slider 4, control the stroke range of the installation device, and prevent the device from exceeding the specified range and causing a safety accident. In addition, the bottom end of the suspension rubber positioning block 8 should be higher than the limit block 6 to avoid interference.

[0024] In this embodiment, the original positioning groove of the suspension rubber positioning block 8 that matches the muffler suspension rubber 9 is improved to a positioning hole 8-3 that penetrates the suspension rubber positioning block 8. This design ensures that the muffler suspension rubber 9 can be accurately aligned during the installation process, improving the accuracy and efficiency of the installation. At the same time, the opening of the positioning hole 8-3 is provided with a chamfer on the side facing the muffler bracket 10, which helps the smooth installation of the suspension rubber and reduces the resistance during the installation process. On the side of the suspension rubber positioning block 8 facing away from the muffler bracket 10, a buffer block 11 is installed. The buffer block 11 is a key component to protect the suspension rubber from damage. In this embodiment, the buffer block 11 uses a rubber piece with a thickness of 8 to 15 mm. This thickness range can ensure that the buffer block 11 has sufficient elasticity and buffering performance, and can avoid the problem of insufficient installation space caused by excessive thickness. The rubber buffer block 11 has good elasticity and wear resistance, can effectively reduce impact force and vibration during installation, and protect the suspension rubber from damage. The buffer block 11 is clamped between the suspension rubber positioning block 8 and the pressure plate 12 by fasteners. In this embodiment, the fasteners are bolts, and the tight connection between the buffer block 11 and the suspension rubber positioning block 8 and the pressure plate 12 is ensured by the tightening effect of the bolts. This connection method is simple and reliable, and can ensure the stability and reliability of the buffer block 11 during the installation process.
