Linear cutting tool for ratchet wheel machining

The utility model relates to the technical field of machining, in particular to a ratchet wheel machining linear cutting tool which comprises a moving table and a moving assembly connected with the moving table, and the moving assembly can drive the moving table to move transversely and longitudinally in the horizontal direction. A ratchet wheel fixing seat is erected on the transfer table; a hollow ratchet wheel containing cavity is formed in the ratchet wheel fixing base in the vertical direction, and the ratchet wheel containing cavity is used for suspending a ratchet wheel to be machined. A plurality of ratchet wheel fixing pieces connected with the ratchet wheel are arranged on the ratchet wheel fixing base in the radial direction. The ratchet fixing piece is used for fixing the ratchet in a suspended mode, it is guaranteed that an enough wire cutting gap is formed between the ratchet element and the inner wall of the ratchet containing cavity of the ratchet fixing base, it can be guaranteed that after a
