Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

Example one

As shown in fig. 1 to 8, the forklift front fork device includes a cylinder 1, a head pipe 2, a hydraulic rod 3, a plate bracket 4, and a front fork 5. The cylinder body 1 is provided with a motor (the motor is not shown), and the motor is used for pumping oil to realize the lifting of the hydraulic rod 3. The push pipe 2 is installed in the cylinder body 1 and fixed on the cylinder body 1 through the push cap 9, the hydraulic rod 3 is movably inserted into the push pipe 2, the push pipe 2 is also fixedly connected with a fork shaft 56 of the front fork 5, a bearing hole 41 is formed in the flat plate support 4, a thrust ball bearing 7 is installed in the bearing hole 41, the cylinder body 1 is pressed on the thrust ball bearing 7, and the cylinder body 1, the push pipe 2 and the front fork 5 synchronously rotate. The bottom of the cylinder body 1 is provided with a first wire passing groove 11, a second wire passing groove 52 is arranged on a fork shaft 56 of the front fork 5, the second wire passing groove 52 is positioned in a first shaft hole 53, a third wire passing groove 51 is also arranged on the front fork 5, the third wire passing groove 51 is positioned on one side of the fork shaft 56, the second wire passing groove 52 and the third wire passing groove 51 are positioned on the same side of the front fork 5, the second wire passing groove 52 is communicated with the third wire passing groove 51, the second wire passing groove 52 is also communicated with the first wire passing groove 11, a lead of the motor sequentially passes through the first wire passing groove 11, the second wire passing groove 52 and the third wire passing groove 51, and the lead is not contacted with the flat support 4, so that friction between the lead and the flat support 4 is avoided, the lead is in a hidden state, the lead is effectively protected, unified wiring, convenience and high safety are achieved.
