[0002] A pallet truck is a common, simple and effective loading and unloading and transporting tool used in the process of cargo handling. The fork is an important part of a manual pallet truck. One end of the fork is used to weld the triangular box, and the lower part is equipped with rollers. The upper part is used to support the fork, and then the goods are dragged away by rolling the rollers.

[0003] After searching: Patent No. CN204038989U is a fork structure for a transport truck, including a fork connecting frame and a pair of main forks connected to one side thereof, and also including an auxiliary fork, the auxiliary fork is connected to the fork connecting frame and is located outside the pair of main forks to increase the load-bearing area outside the main forks of the fork structure. The fork structure of the utility model has high balance stability and is not prone to rollover when used to transport large-volume and high-center-of-gravity goods.

[0004] However, the fork structure of the above-mentioned transport truck still has some shortcomings. The distance between the two forks of the transport truck is relatively fixed, which is inconvenient to adjust according to actual conditions, reducing the versatility of the transport truck. In addition, the width of the fork is relatively fixed and inconvenient to widen. When transporting larger goods, the wider goods are easy to tip over from both sides of the fork and cause the goods to be damaged. Therefore, we propose a fork for a transport truck to solve the above problems. Utility Model Content
