[0001] The utility model relates to a forklift accessory technical field more specifically, relate to a forklift operating handle and forklift. BACKGROUND

[0002] Forklift, as a common handling tool, plays an important role in the field of logistics, warehousing and so on. In the existing forklift design, the handle main body and the support are usually fixedly connected, wherein the support is rotatably connected with the manual hydraulic cylinder through a pin shaft. The support is usually a U-shaped structure in cross section, and one end of the handle main body is located in the U-shaped groove and fixedly connected with the support. In order to realize flexible rotation, holes adapted to the pin shaft are provided on the two side walls of the support. However, in the existing design, the axial length of the hole is equal to the wall thickness of the support, resulting in a short contact surface. This design will cause local stress concentration due to the insufficient contact area of the hole and the pin shaft in actual use, thereby accelerating the wear rate of the hole, shortening the service life of the whole assembly and increasing the maintenance cost.
