[0002] The utility model patent with application number: CN202222824039.8 discloses an open linear slider milling groove fixture, including a fixed seat, a mounting plate, a clamping assembly and a pressing assembly. The fixed seat and the mounting plate are fixed vertically to each other. The clamping assembly includes a U-shaped clamping frame fixed relatively to the mounting plate. A clamping cavity for adapting to clamping the open linear slider is provided between the mounting plate and the U-shaped clamping frame. An inlet connected to the clamping cavity is provided at one end of the U-shaped clamping frame. A limiting member that forms a limiting match with the open linear slider is provided at the other end of the U-shaped clamping frame. A milling groove opening corresponding to the side of the open linear slider is provided on one side of the U-shaped clamping frame. The U-shaped clamping frame is provided with an arc segment and a straight segment corresponding to the milling groove opening. The milling groove opening includes an arc processing area corresponding to the arc segment and a square processing area corresponding to the straight segment. The arc processing area and the square processing area are connected to each other; the pressing assembly includes a threaded rotating rod threadedly connected to the mounting plate, and the threaded rotating rod forms abutment match with the open linear slider. When the above technical solution is used, the open linear slider to be processed can be directly slid into the clamping cavity through the inlet, and one side end face of the open linear slider abuts against the limiter to form a limit, and the back of the open linear slider is pressed against by the threaded rotating rod to maintain the clamping and locking state.
