[0017] like Figure 1 As shown, the present invention is a butterfly fork, comprising a fork body 1, with drive motors 2 symmetrically mounted on both sides of the fork body 1, the output shaft of the drive motor 2 facing outward, and the output shaft of the drive motor 2 connected to the butterfly finger 3. The butterfly finger 3 is an arc-shaped structure.

[0018] like Figure 2-4 As shown, a butterfly fork mounting structure includes an upper fork body 4, a middle fork body 5 is connected to the lower part of the upper fork body 4, and a butterfly fork is connected to the lower part of the middle fork body 5.

[0019] like Figure 2 As shown, a sprocket mounting seat 4-1 is mounted on the upper portion of the upper fork body 4, a drive sprocket shaft 4-2 is rotatably mounted in the sprocket mounting seat 4-1, a drive sprocket 4-3 is provided in the middle of the drive sprocket shaft 4-2, and a drive motor 4-4 is connected to one side of the drive sprocket shaft 4-2. A driven sprocket mounting seat 4-5 is mounted on the lower portion of the upper fork body 4, and a left driven sprocket 4-6 and a right driven sprocket 4-7 are symmetrically rotatably mounted in the driven sprocket mounting seat 4-5. A chain notch is formed in the upper fork body 4 above the driven sprocket mounting seat 4-5.

[0020] like Figure 3-4 As shown, the middle fork body 5 is provided with a left-shift chain groove and a right-shift chain groove. The left-shift chain groove is divided into an upper left chain groove 5-1 and a lower left chain groove 5-2, while the right-shift chain groove is divided into an upper right chain groove 5-3 and a lower right chain groove 5-4. The upper left chain groove 5-1 and the upper right chain groove 5-3 are located at the upper portion of the middle fork body 5, while the lower left chain groove 5-2 and the lower right chain groove 5-4 are located at the lower portion of the middle fork body 5. As shown in the figure, a middle fork drive chain 5-5 is disposed between the upper left chain groove 5-1 and the upper right chain groove 5-3. One end of the middle fork drive chain 5-5 is located on the left side of the middle fork body 5. The middle fork drive chain 5-5 engages with the bottom of the left driven sprocket 4-6, passes upward through the chain gap, engages with the upper end of the drive sprocket 4-3, then passes downward through the chain gap, engages with the bottom of the right driven sprocket 4-7, and is finally fixed to the right side of the middle fork body 5.

[0021] like Figure 4 As described, a right-shift sprocket 4-8 is set at the bottom left side of the upper fork body 4, a right-shift fixed block 5-6 is set in the lower right chain groove 5-4, the right end of the right-shift fixed block 5-6 is connected to the lower end of the right-shift chain 5-7, and the right-shift chain 5-7 bypasses the right end of the middle fork body 5 and enters the upper right chain groove 5-1, and then bypasses the right-shift sprocket 4-8 and is fixed to the middle part of the middle fork body 5.

[0022] A left-shift sprocket is provided at the bottom right side of the upper fork body 4, and a left-shift fixed block is provided in the lower left chain groove 5-2.

[0023] The rightward moving fixed block 5 - 6 and the leftward moving fixed block are both connected to the fork body 1 .

[0024] The working process of the present invention is as follows:

[0025] Drive motor 2 rotates 45° clockwise and counterclockwise, transmitting this rotation to butterfly fingers 3, similar to the movement of a butterfly spreading its wings. This allows for the clamping of boxed cargo. The retraction process is the same as the removal of cargo. The storage process is the opposite of this.

[0026] The upper fork body 4 is fixed on the equipment, the drive motor 4-4 is started, the drive motor 4-4 rotates clockwise, and the middle fork drive chain 5-5 drives the middle fork body 5 to move right. At the same time, the middle fork body 5 pushes the middle part of the right shift chain 5-7 to the right, so that the right shift fixed block 5-6 drives the fork body 1 to move right.

[0027] If the fork body 1 needs to move to the left, the driving motor 4-4 is rotated counterclockwise.
