It can make the entire exhaust system flexibly connected, thereby reducing vibration and noise, facilitating installation, and extending the life of the exhaust and muffler system. Generally speaking, the exhaust pipe of a forklift can be straight or curved. The straight exhaust pipe is simple in design and easy to install and maintain, but in some cases it may not optimize the exhaust flow as well as the curved pipe design. During production, both straight and curved exhaust pipes need to be positioned and fixed, and then welded and polished. However, most existing fixing devices can only fix straight pipes, and when fixing curved pipes, they often cannot adapt to the curvature of the curved pipes and can only fix the local position of the curved pipe. The fixing effect is poor and easily affects subsequent processing. Therefore, in order to solve the above problems, it is urgent to propose a new positioning and fixing device for the production of forklift exhaust pipes. Utility Model Content
