Referring to FIG. 23, FIG. 24 and FIG. 26, it is a schematic view of the appearance of the fourth embodiment of the present invention. The difference between this embodiment and the foregoing embodiment is that the center base 5 and the first base 3 have an oblique groove structure which is generally in the shape of a font (a gourd shape). Here, each central oblique groove 54 of the center base 5 includes a central outer expansion region 541 formed by the outward direction of the center of the outer base, a central connection region 542, and a central inner expansion region 543, as a whole, the central oblique groove 54 is a generalized 8 font (goose shape) in a plan view. In other words, the central connecting region 542 of the central oblique groove 54 is an intermediate tapered portion having a width smaller than the width of the central outer expanded region 541 and the central inner expanded region 543 at both ends. The central outer expansion zone 541 may be substantially equal to or smaller than the width of the central inner expansion zone 543. In addition, the central outer expansion region 541 is in an open configuration, and the outer rod is inserted into the central oblique groove 54 from the central outer expansion region 541.

Referring to FIGS. 23 and 26, the oblique joint portion 39 of each of the first pedestals 3 includes a joint outer expansion region 391 formed by the outward direction of the center of the susceptor, a joint connection region 392, and a joint inner expansion region 393. . Here, the joint outer expansion region 391, the joint connection region 392, and the joint inner expansion region 393 are the same as the aforementioned central outer expansion region 541, the central connection region 542, and the central inner expansion region 543, and will not be described herein.

Referring to FIG. 23, FIG. 24 and FIG. 26, one end of the slanting rod 29 is inserted into the central oblique groove 54 through the central outer expansion region 541 during assembly, and the slanting rod 29 is abutted by the central connecting portion 542. So that the slanting rod 29 can rotate in the space of the central outer expansion region 541 and the central inner expansion region 543 centering on the central connection region 542; the other end of the diagonal rod 29 passes through the outer expansion region of the joint portion 391 is inserted into the oblique joint portion 39, and the joint portion 392 is abutted against the slanting rod 29, so that the slant rod 29 can be rotated in the space of the joint outer expansion region 391 and the joint inner expansion region 393 centering on the joint portion 392. (As shown in Fig. 29), the angle between the slanting rod 29 and the straight rod 21 is changed from θ 1 to θ 1 '.

Referring again to Figures 23 to 28, when the slanting rod 29 is rotated in the central oblique groove 54 and the oblique joint portion 39, the angle between the slanting rod 29 and the straight rod 21 (or the cross rod 22) is made. The pallet frame 2 of different shapes, such as different sizes or squares, elongated shapes, etc., can be constructed. This part is further described with reference to the drawings as follows: Referring to Figures 24 and 27, the overall length L1 of the combined pallet 1 (i.e., the distance between the two longitudinal sides of the first pedestal 3) is the same as the overall width L2. (ie, the lateral distance between the two first pedestals 3 in the lateral direction), for example, the overall length L1 and the overall width L2 of the combined pallet 1 are 1100 cm, and the angle between the slanting rod 29, the straight rod 21 and the crossbar 22 is θ 1 is 45 degrees, the included angle θ 2 is 90 degrees, and the included angle θ 3 is 45 degrees. At this time, both ends of the slanting rod 29 can be sandwiched by the joint connecting portion 39225 and the central connecting portion 542, respectively. Referring to Figures 24 and 28, if the overall length L1' of the pallet (e.g., the distance between the two first bases 3 in the longitudinal direction) is 1000 cm, and the overall width L2' (such as the two first bases in the lateral direction) When the distance between the seat 3 and the outer side is 1200 cm, the angle θ 1 ′ between the slanting rod 29 , the straight rod 21 and the cross rod 22 is 52 degrees, the angle θ 2 is 90 degrees, and the angle θ 3 ′ is 38 degrees. At this time, the entire combined pallet 1 of FIG. 27 and the angle between the angle θ 1 and the angle θ 3 are different from the angle of the entire combined pallet 1 of FIG. 28 and the angle θ 1 ′ and the angle θ 3 ′, respectively. However, the two ends of the slanting rod 29 can also be sandwiched by the joint connecting portion 392 and the central connecting portion 542, respectively. That is, the central outer expansion region 541 and the central inner expansion region 543 allow one end of the diagonal rod 29 to be clamped by the central connection portion 542 after changing the angle, and the other end of the diagonal rod 29 is also expanded outside the joint portion. The angle is changed in the region 391 and the expansion region 393 in the joint portion It can be held by the joint connection area 392. Therefore, regardless of the change in the size of the pallet frame 2 or the shape of the pallet frame 2 being square or elongated, the same central base 5 and the first base 3 can be applied (shared).

In addition, each of the bases may further be provided with a bead structure. As shown in FIG. 30, the first base 3 and the second base 4 may extend on one side thereof with a bead 7A, wherein the bead 7A is a protruding structure. It can be used to buffer the external impact and can be used to position the pallet frame 2, and the sides of each of the strips 7A abut against the sides of the straight rod 21 and the cross rod 22, respectively.

As shown in FIG. 11 , FIG. 13 and FIG. 14 , it is particularly noted that the straight rod 21 and the cross rod 22 can be connected to only the connecting rod 24, or only the positioning portion 214/224 can be used (eg, As shown in Fig. 21, or alternatively, the connecting rod 24 is used together with the positioning portion 214/224. For example, the use of the connecting rod 24 on the straight rod 21 and the cross rod 22 can be used as an example, that is, the assembling straight rod 21 and the cross rod 22 and the first base 3 can be connected to each other and stably fixed. In this case, it can be omitted. The structure of the positioning portions 214/224 is set to reduce the structural cost.
