Wherein, the fixed block 120 is disposed on the first substrate 110, the fixed block 120 is provided with an adjusting slot 121 and an adjusting hole 122, and the adjusting hole 122 is communicated with the adjusting slot 121. The fork handle 130 is disposed at a side of the fixed block 120, and the fork handle 130 is provided with an assembly hole 131, and the assembly hole 131 corresponds to the adjustment groove 121. The connecting piece 140 is inserted between the adjusting groove 121 and the assembling hole 131, the connecting piece 140 is provided with a threaded hole 143 corresponding to the adjusting hole 122, the adjusting piece 150 is arranged on the fixed block 120 and is in spiral fit with the threaded hole 143, and when the adjusting piece 150 is rotated, the connecting piece 140 is forced to lift in the adjusting groove 121, so that the fork handle 130 is driven to lift.

The positioning nut cap 154 cooperates with the adjusting block 153 to position the adjusting member 150, and the diameter of the positioning nut cap 154 is larger than that of the adjusting hole 122, so that when the screw 152 rotates downward in the adjusting hole 122, the positioning nut cap 154 cannot enter the adjusting hole 122, and the screw 152 can be positioned and fixed on the fixing block 120. The positioning nut cap 154 has a larger diameter than the positioning hole 1531 of the adjustment positioning block 153, so that when the screw 152 rotates upward in the adjustment hole 122, the positioning nut cap 154 cannot enter the positioning hole 1531, so that the screw 152 can be positioned and fixed on the adjustment positioning block 153. The adjusting hole 122 is coaxially corresponding to the threaded hole 143, the screw 152 passes through the adjusting hole 122 and can be in screw fit with the threaded hole 143, when the adjusting cap 151 is rotated, the screw 152 is positioned and fixed, and only rotation can be performed, and up-and-down movement cannot be performed, so that the connecting piece 140 in threaded connection with the screw 152 is forced to perform up-and-down movement in the adjusting groove 121. The fork handle 130 is horizontally fixed to the fixing block 120 through the connection member 140, and the fixing block 120 is fixed to the first substrate 110 through screws, but the fork handle 130 is not fixed to the first substrate 110 (that is, the fork handle 130 can move up and down). When the adjustment cap 151 is rotated clockwise, the screw thread of the screw 152 is engaged with the screw thread depth of the screw hole 143, so that the connection member 140 makes an ascending motion in the adjustment groove 121, thereby driving the fork handle 130 to ascend.

In summary, as will be readily understood by those skilled in the art, when the adjusting member 150 is rotated on the fork assembly 100, the connecting member 140 is forced to lift in the adjusting slot 121, so as to drive the fork handle 130 to lift and adjust, so that when the fork truck including the fork assembly 100 is used for loading and unloading materials, the material tray placed on the fork handle 130 is kept stable, so that the materials on the tray are not easy to topple, and meanwhile, the rocking wheel 260 is rotated on the fork mechanism 10 to drive the first screw 250 connected with the rocking wheel 260, so that the first screw 240 in spiral fit with the first screw 250 can move along the left-right direction, and when the position of the fork mechanism 10 of the fork truck 1 is not aligned with the position of the materials, the rocking wheel 260 can be adjusted to position the left-right position of the fork mechanism 10, so that the fork truck 1 can more accurately feed materials from the processing station, without waiting for the materials to cool down, the production efficiency is effectively improved, and the transportation requirements of ceramic filter materials under different environments are satisfied.
The foregoing is only the embodiments of the present application, and therefore, the patent scope of the application is not limited thereto, and all equivalent structures or equivalent processes using the descriptions of the present application and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the application.
