[0010] The utility model will be further described below in combination with the drawings and specific embodiments.

[0011] As shown in the accompanying Figure 1 -attached Figure 3 The embodiment includes: outer cavity mounting seat 1, scraper swing arm 2, piston rod 3, rotating shaft 4, air inlet hole 5, bolt 6, pressure knife plate 7, blade 8 and sealing ring 9.

[0012] The upper and lower end faces of outer cavity mounting seat 1 have a through rectangular cavity, and a pair of coaxial through holes are arranged at the front and rear respectively, the front side is a bolt hole, and the rear side is a cylindrical hole, for installing the rotating shaft 4, the rotating shaft 4 is arranged in the outer cavity mounting seat 1, and the outer cavity mounting seat 1 is provided with symmetrical cylinder bodies on the left and right sides, the piston rod 3 can move left and right in the corresponding cylinder bodies and install the air inlet hole 5 outside the cylinder body, and four threaded holes are arranged at the rear side for installing the device. The rotating shaft 4 is a cylindrical structure, and one end is provided with an external thread. The scraper swing arm 2 is provided with through holes at the front and rear, and four through bolt holes are arranged on the left and right sides, and the blade 8 is clamped by four bolts 6 pressing the pressure knife plate 7, and the pressure knife plate 7 is a rectangular structure, and four through holes are arranged on the left and right sides. One end of the piston rod 3 is provided with a sealing groove, and the sealing ring 9 is embedded in the sealing groove.

[0013] The working principle of the embodiment is described in detail as follows:

[0014] In the working process, the gas with appropriate pressure is input through the air inlet hole 5, and the gas directly enters each cylinder body, so that each piston rod 3 is completely stretched out and abuts against the scraper swing arm 2 at the same time, the scraper swing arm 2 is centered, the device is moved, the blade 8 is moved along the burr to be processed, and at the same time, the piston rod 3 is pushed, because the gas pressure is constant, the processing force is also kept unchanged, the processing quality is guaranteed, and the tool is protected, automatic batch processing is realized, manual labor is saved, and production cost is effectively reduced.

[0015] The above embodiment is only preferred and exemplary, and those skilled in the art can make equivalent technical improvements according to the spirit of the patent, and these are covered by the protection scope of the patent.
