The two second insertion openings 231 each extend through the second clamping plate 23 in a direction perpendicular to the second clamping plate 23 and are connected to the bottom. The two second insertion openings 231 are arranged at the two ends of the top side edge of the second clamping plate 23, and the sum of the lengths of the first insertion openings 221 and the second insertion openings 231 is equal to the height of the first clamping plate 22 and the second clamping plate 23. When assembled, the two first clamping plates 22 are inserted into the four second clamping plates 23 through the four first insertion openings 221 and the one second insertion opening 231 to form a cross shape, and finally all the first clamping plates 22 and the second clamping plates 23 are inserted into each other to form the inner packaging part 2 and enclose the three placement cavities 24. The number of the first clamping plates 22 and the second clamping plates 23 is not limited to the embodiment, and other numbers of the first clamping plates 22 and the second clamping plates 23 can also be used, but it is necessary to ensure that the first clamping plates 22 and the second clamping plates 23 are provided as at least two pieces, so as to ensure that at least one placement cavity 24 can be enclosed. The top and bottom of the first clamping plates 22 and the second clamping plates 23 after being inserted into each other through the first insertion openings 221 and the second insertion openings 231 are flush. The side on which the first clamping plates 22 are arranged is the width of the placement cavity 24, the side on which the second clamping plates 23 are arranged is the length of the placement cavity 24, and the placement cavity 24 is a rectangular cuboid. The placement cavity 24 needs to be adapted to the cylinder head, so that the side wall of the cylinder head fits the inner wall of the placement cavity 24, thereby preventing the cylinder head from rolling.

[0033] In the embodiment, in order to avoid the impact of the surrounding plate 13 on the cylinder head in the placement cavity 24 due to collision with the shell during transportation, end plates 25 are formed at the two ends of each of the first clamping plates 22 and the second clamping plates 23 after being inserted into each other in a straight line, and are located outside each of the placement cavities 24, i.e., outside the inner packaging part 2. The end plates 25 abut the inner side of the surrounding plate 13 of the outer packaging layer 1 when the surrounding plate 13 encloses the inner packaging part 2. The end plates 25 form a support between the surrounding plate 13 and the inner packaging part 2, and at the same time form the anti-collision space 26 between the inner packaging part 2 and the outer packaging layer 1, so that the surrounding plate 13 and the parts of the first clamping plates 22 and the second clamping plates 23 other than the end plates 25 are spaced apart, thereby greatly reducing the impact on the cylinder head when the surrounding plate 13 is collided.

[0034] In the embodiment, the auxiliary hoisting part 3 comprises two limiting blocks 31 which are arranged on the bottom of the placing cavity 24 at both sides of the width direction of the placing cavity 24, and the two limiting blocks 31 are located at the middle part of the placing cavity 24 along the length direction of the placing cavity 24. When the cylinder head is installed in the placing cavity 24, the bottom of the cylinder head is supported on the top of the limiting blocks 31 to support the cylinder head. After the support, the top of the cylinder head is flush with the top of the placing cavity 24, so that the upper cover 14 or other inner packaging part 2 cover arranged on the top of the placing cavity 24 can press the cylinder head. The hoisting space 33 for the hoisting rope to pass through is arranged between the two limiting blocks 31, so that the hoisting rope can be conveniently operated after the cylinder head is installed in the packaging box, and the hoisting rope is pulled to pass through the hoisting space 33. The auxiliary hoisting part 3 is formed by folding a rectangular base plate to have two layers. The folded side 311 of the base plate is fixedly connected to the bottom of the placing cavity 24, i.e. the layer plate 21 by pasting or other methods. In order to improve the stability of the limiting block 31, the folded side 311 of the limiting block 31 is abutted against the side wall of the placing cavity 24, i.e. the second clamping plate 23. The limiting block 31 can also be formed by pasting two wooden strips, which is not limited to the embodiment. In another embodiment, corresponding to part of the cylinder head, the limiting block 31 in each placing cavity 24 can be provided as one, so that the two sides of the cylinder head are in a high-low shape. Correspondingly, the depth of the placing cavity 24 should be such that the upper cover 14 can press on the cylinder head after the cylinder head is placed in a high-low shape, so as to prevent the cylinder head from jumping, and at the same time, the hoisting space 33 is also left at the bottom of the cylinder head.

[0035] Please refer to Figure 5 In another embodiment, the auxiliary hoisting part 3 comprises a pulling part 32 in addition to the limiting block 31. The pulling part 32 comprises a partition 321 arranged in the anti-collision space 26, a pull rod 322 fixedly connected to one end of the partition 321, and a pull hook 323 fixedly formed on the other end of the pull rod 322. The first clamping plate 22 is provided with a through hole which communicates with the placing cavity 24 at the position opposite to each placing cavity 24. The pull rod 322 is movably arranged through the through hole, and one end of the pull hook 323 is arranged in the placing cavity 24. The through hole is opposite to the hoisting space 33, and the pull rod 322 and the pull hook 323 are arranged in the hoisting space 33. The diameter of the partition 321 is greater than that of the through hole. When the partition 321 is abutted against the first clamping plate 22, the pull hook 323 is close to or abutted against the other first clamping plate 22. When the cylinder head is removed, the hoisting rope can be hooked on the pull hook 323. By pulling the partition 321 outward, the pull hook 323 drives the hoisting rope to move to the other end of the hoisting space 33, so as to bypass the bottom of the cylinder head, thereby facilitating hoisting of the cylinder head, and assisting assembly of the hoisting rope.
