the storage rod (250), the slide way (210) and the swinging block (240) are all arranged on a mounting seat (200), the mounting seat (200) and the slide block (100) form a detachable connection, and the slide way (210) and the contact plate (110) form a detachable connection;
the storage rod (250) and the mounting seat (200) are detachably connected;
slots (201) are formed in two sides of the mounting seat (200), protruding strips (101) matched with the slots (201) are arranged on the inner sides of the two side walls of the sliding block (100), the mounting seat (200) and the sliding block (100) are in insertion fit through the slots (201) and the protruding strips (101), and set screws (102) are arranged on the positions, corresponding to the slots (201), of the side walls of the sliding block (100);
the material storing device is characterized in that a limiting disc (253) is arranged at one end, far away from the slide way (210), of the material storing rod (250), at least two buckles (254) protruding outwards in the radial direction are symmetrically arranged at the edge of the limiting disc (253), a material storing rod mounting hole (203) for the material storing rod (250) to pass through is formed in the mounting seat (200), and a rotary inserting type clamping groove (204) matched with the buckles (254) is formed in the edge of the material storing rod mounting hole (203).
