Since the second transmission frame 23 and the connecting rod 13 are fixedly connected by screws, the connecting rod 13 is driven to perform linear motion. Since the head and tail of the first moving groove 21 are closed, the piston 12 is driven to perform reciprocating linear movement, allowing the water pump to pump water or deliver water.
