[0028] In this embodiment, a storage mechanism 102 is provided at the bottom of the front frame 1. The storage mechanism 102 includes two rotating plates 13. The two rotating plates 13 are arranged on the front of the front frame 1. A rotating rod 14 is fixedly installed through the inside of the rotating plate 13, and the rotating rod 14 penetrates through the inside of the front fork plate 19. A tooth groove 15 is opened on the outer side of the rotating plate 13. A positive and negative motor 16 is provided at the bottom of the front frame 1. A gear 17 is fixedly installed on the outer side of the output end of the positive and negative motor 16, and the gear 17 meshes with the tooth groove 15. The storage mechanism 102 further includes a fixed seat 8. The fixed seat 8 is fixedly installed at the bottom of the front frame 1 through a plurality of bolts, and the fixed seat 8 is located at the center position of the bottom of the front frame 1. Two machine bases 9 are fixedly installed at the bottom of the front frame 1 through a plurality of bolts, and the two machine bases 9 are respectively located on both sides of the fixed seat 8. Fixed blocks 10 are respectively fixedly installed at the bottoms of the machine base 9 and the fixed seat 8. Two fixed rods 11 are fixedly installed between the three fixed blocks 10, and the two fixed rods 11 are respectively located on both sides of the fixed seat 8.

When the positive and negative motor 16 rotates, the positive and negative motor 16 drives the gear 17 to rotate, so that the gear 17 drives the rotating plate 13 to rotate by using the meshing action with the tooth groove 15. The rotating plate 13 drives the rotating rod 14 to rotate around the center plate 12. The rotating rod 14 drives the front fork plate 19 to rotate, so that the front fork plate 19 rotates around the fixed rod 11 under the drive of the rotating rod 14. The front fork plate 19 rotates through the support of the side plate 18 and the fixed rod 11.

[0030] In this embodiment, an adjusting component 101 is arranged inside the front frame 1. The adjusting component 101 drives the lead screw 4 to rotate through a double-headed motor 3 arranged inside the front frame 1, thereby driving the two front fork arms 5 to move left and right. There is a cross plate at the middle position of the front frame 1. A chute 2 is opened at the top of the cross plate. The double-headed motor 3 is fixedly installed at the middle position of the cross plate. The two lead screws 4 are fixedly installed at the two output ends of the double-headed motor 3, and the other end of the lead screw 4 is installed through the inner walls on both sides of the front frame 1 through bearings. The thread directions of the two lead screws 4 are opposite. There is a downward protruding part inside the front fork arm 5. The protruding part is located inside the chute 2, and the lead screw 4 threadedly penetrates the inside of the protruding part.

[0031] Specifically, the front frame 1 can provide a space for opening the chute 2. The chute 2 can provide a sliding space for the protruding part of the front fork arm 5. The front frame 1 can provide a stable support for the double-headed motor 3. The double-headed motor 3 can provide a rotational power for the two lead screws 4. When the double-headed motor 3 drives the lead screw 4 to rotate, the lead screw 4 drives the front fork plate 19 to move by means of the threaded action with the front fork arm 5, so that the two front fork plates 19 move in the direction of moving away from or approaching each other, and the distance between the two front fork plates 19 is adjusted.

[0032] Working principle: The staff first installs the front frame 1 on the front of the forklift. Before use, start the double-headed motor 3 to drive the lead screw 4 to rotate first, so that the lead screw 4 drives the two front fork arms 5 to move away from or approach each other by means of the threaded action with the front fork arm 5. After adjusting the two front fork plates 19 to a suitable distance through the front fork arms 5, then use it. After use, the staff starts the two forward and reverse motors 16 to rotate synchronously, so that the forward and reverse motors 16 drive the gear 17 to rotate. The gear 17 drives the rotating plate 13 to rotate 90° towards the front by means of the meshing action with the tooth groove 15, so that the rotating plate 13 drives the rotating rod 14 to rotate 90° with the center plate 12 as the center. The rotating rod 14 drives the side plate 18 and the front fork plate 19 to rotate with the fixed rod 11 as the center, so that the front fork plate 19 rotates 90° from the horizontal state to the vertical state, and the front fork plate 19 fits with the front fork arm 5, realizing the storage of the front fork plate 19.
