The conventional auger bit structure 1 includes a rod body 11, a screw head 12 provided on one end of the rod body 11, a drill tail 13 provided on the other end of the rod body 11, and a plurality of threads 14 arranged around the rod body 11; Wherein, the periphery of the drill tail 13 defines a parting line 15, and the parting line 15 makes the drill tail 13 symmetrically divided into a side 131 and a side 132, and a cutting end 133 is formed at the junction of the end of the side 131 and the end of the side 132, respectively. The cutting end 133 is concavely provided with a quarter-turn chip flute 134 in the same direction of the helix, and the edge 132 continues the chip flute 134 and has a quarter-turn chip flute 135 with different helical curvatures. , using the chip groove 134 and the chip groove 135 to be connected by different helical curvatures, so that the drill tail 13 can form a symmetrical and complete chip groove of 190 degrees.
Spring mattresses and spring seat cushions are modern and commonly used furniture products with better performance, and their cushion cores are composed of springs. It makes full use of the advantages of good spring elasticity, good support, strong air permeability and durability. The traditional spring pad is a spring with a thicker wire diameter, which is connected and fixed by steel wires, and has high hardness. Most of the elders of the older generation often use linked spring beds, but if they sleep in a fixed position for a long time or are accustomed to sitting on the side and corners of the bed, or flip the mattress irregularly, it is easy to cause depression and elastic fatigue.
