[0018] The utility model discloses a pneumatic device, which can realize precise cutting after a blade 33 is installed on the pneumatic device, and the blade is not easy to break.

[0019] The utility model discloses a pneumatic device including a handle 6 with an air guide ring 34 installed on the top, a cutter head assembly installed at the bottom of the handle 6, the air guide ring 34, the handle 6, and the cutter head assembly are connected in sequence, the air guide ring 34 is provided with an air inlet joint and an air exhaust joint, the cutter head assembly includes a cutter body 29 with a cylinder shaft 26 installed inside and a sliding block 30 connected to the cylinder shaft 26, a cutter head air inlet joint 13a and a cutter head air exhaust joint 13b are installed on the cutter body 29, and the air entering and exiting the cutter body 29 can drive the cylinder shaft 26 to move up and down, thereby driving the sliding block 30 to move up and down.

[0020] When the equipment works with a two-position three-way solenoid valve, the air intake and exhaust states of the fixed air intake connector 2a and the fixed air exhaust connector 2b are controlled by the two-position three-way solenoid valve. When the fixed air intake connector 2a takes in air, the internal air path of the tool handle 6 connected to the air guide ring 34 will guide the gas to finally reach the cutter head air intake connector 13a. At this time, the cutter head exhaust connector 13b is exhausted through the guidance of the internal air path of the tool handle 6 and the fixed exhaust connector 2b. The power generated by the air intake and exhaust paths drives the cylinder shaft 26 of the cutter head assembly to slide up and down in the cutter body 29, driving the sliding block 30 to move up and down. The sliding block 30 is connected to the blade 33. When the sliding block 30 slides, the blade 33 also slides to enable the blade 33 to be inserted into the material or withdrawn from the material.

[0021] The beveling process performed by the pneumatic device of the utility model is decomposed into two actions: one is cutting, inserting the blade 33 into the material, and the other is cutting. When the power generated by the air intake and exhaust paths of the pneumatic device of the utility model drives the cylinder shaft 26 of the cutter head assembly to slide up and down in the cutter body 29, it will drive the sliding block 30 to move up and down along the sliding shaft 28. The cylinder shaft 26 and the sliding block 30 are fixed as a whole through the connecting plate 25 and the connecting shaft 27. When the cylinder shaft 26 slides in the cutter body 29, the sliding block 30 will also slide with it. The blade 33 is fixed on the sliding block 30 through the mounting plate 31 and the cover plate 32. When the sliding block 30 slides, the blade 33 will also slide with it, so that the blade 33 is inserted into the material or withdrawn from the material. The utility model solves the problem that the traditional cutting speed is easy to break the blade. After the cutting is completed, cutting is performed. The beveling knife is used to open a V-shaped groove on cardboard or pearl cotton, which is then easy to fold into a box shape.
