The plate material is placed on the platform on the base of the cutting machine, and the cutting machine is started to cut through the movement of the cutting tool. However, the existing plate clamping tool generally uses a positioning pin to fix the material, which is not convenient to operate. Moreover, the automaticity of the movement for cutting, clamping or clamping is low because the material is generally moved manually.

[0003] For example, Chinese patent CN201510018420.7 relates to a vertical band saw cutting machine, which mainly consists of a frame, an electric motor, a transmission mechanism, a band saw, and a reinforcing mechanism. The frame provides connection support for various devices. The frame support surface is provided with a material conveying mechanism on both sides. The electric motor provides cutting power. The transmission mechanism includes a drive belt pulley, a transmission belt pulley, and a band saw. The reinforcing mechanism includes a band saw upper tightening mechanism, a pressure stabilizing block, and a pressure stabilizing spring. The vertical band saw cutting machine drives the band saw perpendicular to the support surface to rotate for cutting. The small cutting edge has high cutting precision. By setting the annular band saw, the cutting diameter and thickness can be greatly lengthened, and the cutting efficiency and speed can be improved.

[0004] For another example, CN201821644457.6 discloses a band saw cutting machine, which belongs to the field of cutting machines. The cutting machine has high working efficiency, is convenient to use, and has high cutting precision. The technical solution comprises an upper machine box and a lower machine box. The upper machine box and the lower machine box are both hinged with a door. The lower machine box is provided with a base at the bottom. The upper machine box and the lower machine box are connected through a frame. The upper machine box is rotatably provided with an upper belt pulley. The lower machine box is rotatably provided with a lower belt pulley. The upper belt pulley and the lower belt pulley are sleeved with an annular saw blade. The base is provided with a driving motor for driving the lower belt pulley to rotate. The driving motor and the lower belt pulley are provided with a transmission assembly. The top surface of the lower machine box is provided with a placing plate. The placing plate and the lower machine box are connected through a sliding assembly. The placing plate is provided with a saw slot for passing through the annular saw blade. The side of the placing plate perpendicular to the sliding direction is provided with a top frame. The cutting machine cuts concrete blocks in an automatic manner, has high cutting speed, and high cutting efficiency.

[0005] The above cutting machines are not convenient for fixing the plate material before cutting. UTILITY MODEL CONTENTS
