[0011] It should be noted that the shape and size of the top plate and the supporting base are limited in the present invention because within the limited range, they can better cooperate with the actual workpiece to be processed and perform subsequent operations. If it is not within the limited range or shape of the present invention, it is very likely that the size of the workpiece to be processed will not meet the standard.

[0012] As a preferred technical solution of the utility model, at least four support bases are provided.

[0013] It should be noted that the present invention does not impose any special restrictions on the specific material of the support base, and technical personnel in this field can make adaptive adjustments based on actual conditions. Among them, limiting the number of support bases to at least four compared to two will provide better stability and make the size of the workpiece to be processed more precise.

[0014] As a preferred technical solution of the utility model, the bottom of the top plate is connected to the support base via bolts, and the top of the top plate is connected to the workpiece to be processed via bolts.

[0015] It should be noted that the present invention does not impose any special restrictions on the bolt models used in bolt connections, and those skilled in the art can make adaptive selections based on actual conditions.

[0016] As a preferred technical solution of the utility model, the top plate is a steel plate or an aluminum plate.

[0017] It should be noted that the top plate in the present invention is a steel plate or an aluminum plate because the material is not easily deformed and has a longer service life.

[0018] As a preferred technical solution of the utility model, the height of the top plate is 35-36 mm, for example, it can be 35 mm, 35.1 mm, 35.2 mm, 35.3 mm, 35.4 mm, 35.5 mm, 35.6 mm, 35.7 mm, 35.8 mm, 35.9 mm, 36 mm, etc., but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0019] Preferably, the length of the top plate is 483-484 mm, for example, it can be 483 mm, 483.1 mm, 483.2 mm, 483.3 mm, 483.4 mm, 483.5 mm, 483.6 mm, 483.7 mm, 483.8 mm, 483.9 mm, 484 mm, etc., but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0020] Preferably, the width of the top plate is 170-180 mm, for example, it can be 170 mm, 170.1 mm, 170.2 mm, 170.3 mm, 170.4 mm, 170.5 mm, 170.6 mm, 170.7 mm, 170.8 mm, 170.9 mm, 180 mm, etc., but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0021] The height of the top plate is limited to 35-36 mm, the length of the top plate is 483-484 mm, and the width of the top plate is 170-180 mm in the utility model. This is because within this size range, the weight of the product can be better borne. If it is not within this range, if it is too large, it will cause material waste and the cutter will easily collide; if it is too small, the service life will be short and it will not be easy to withstand product quality.

[0022] As a preferred technical solution of the utility model, the support base is integrally formed, and each of the support bases includes a vertical column and a horizontal column, and one end of the vertical column and one end of the horizontal column are connected to form an L-shaped structure.

[0023] As a preferred technical solution of the utility model, the upright column is provided with a slot at one end perpendicular to the horizontal column, and the surface of the top plate is provided with a through slot, and the slot and the through slot are detachably connected by bolts.

[0024] It should be noted that the specific dimensions of the slot and the through slot are not specifically limited in the present invention, and the two can be connected by the same bolt, and those skilled in the art can make adaptive adjustments according to actual conditions.

[0027] The height of the column is limited to 110-120 mm, and the width of the column is limited to 40-50 mm, because within this size range, the processing efficiency can be higher. If it is not within this range, if it is too small, the tool handle will hit the workbench and the machine spindle will hit it during processing, and if it is too high, it will cause insufficient strength and affect the processing effect.

[0028] As a preferred technical solution of the utility model, the horizontal column is provided with an opening in a direction parallel to the vertical column, and the opening is used for bolting the machine tool.

[0029] It should be noted that the specific size of the opening is not particularly limited in the present invention, and the opening and the fixing hole on the machine tool can be connected by the same bolt, and those skilled in the art can make adaptive adjustments according to actual conditions.

[0030] As a preferred technical solution of the present invention, the length of the horizontal column is 120-130 mm, for example, it can be 120 mm, 120.1 mm, 120.2 mm, 120.3 mm, 120.4 mm, 120.5 mm, 120.6 mm, 120.7 mm, 120.8 mm, 120.9 mm, 130 mm, etc., but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0031] Preferably, the height of the horizontal column is 48-50 mm, for example, it can be 48 mm, 48.2 mm, 48.4 mm, 48.6 mm, 48.8 mm, 49 mm, 49.2 mm, 49.4 mm, 49.6 mm, 49.8 mm, 50 mm, etc., but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0032] The utility model limits the length of the horizontal column to 120-130 mm and the height of the horizontal column to 48-50 mm, because installation is more convenient within this size range. Too large a size will cause material waste and the risk of collision during processing, while too small a size will have poor load-bearing capacity.

[0033] Compared with the prior art, the beneficial effects of the utility model are:
