Described second screw thread revolves direction contrary with described first screw thread revolving direction, described second screw thread is provided with multiple thread two, and the tooth of described thread two is apart from the tooth than described thread one apart from large.
Described thread one is provided with the first cutting face and the second cutting face, the angle of described first cutting face and a horizontal axis is between 15-25 degree, the angle of described second cutting face and described horizontal axis is between 5-15 degree, and the skew direction that described tail cutting slot upwards extends is identical with described first screw thread revolving direction.
The beneficial effect of technique scheme of the present utility model is as follows:
The screw of wood furniture of the present utility model, first, outside due to hypomere is provided with one first screw thread, first screw thread is provided with multiple thread one and thread one is asymmetric thread, and the outside of epimere is provided with one second screw thread, and it is contrary with the first screw thread revolving direction the second screw thread to revolve direction, second screw thread is provided with multiple thread two, the tooth of thread two, apart from the tooth than thread one apart from large, so be conducive to the speed improving DRIVE SCREWS, is increased work efficiency; In addition, because hypomere is provided with the tail cutting slot extended towards direction, termination from insertion end, bearing of trend and the longitudinal axis shape of tail cutting slot have angle, angle is between 3-9 degree, and the horizontal section of hypomere is equilateral triangle, is conducive to chip to be discharged in time, reduce resistance, thus increase work efficiency; In addition, when the epimere of screw screws in timber, screw thread two has the effect having reaming, hypomere successfully can be screwed in timber and make epimere completely closely to go deep in timber, reach the object of firm timber and timber, the asymmetric thread one of the first screw thread has easily to be locked and the effect not easily exited, and can improve the combination force of screw.

Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Fig. 1 to Fig. 3, the utility model embodiment provides a kind of screw 20 of wood furniture, screw 20 is provided with a body of rod 22, the body of rod 22 is provided with insertion end 24, straight section and termination 26 at y direction, straight section is located between insertion end 24 and termination 26, insertion end 24 is in drill-bit type, the upper surface of termination 26 has one turn of hole 28 and rotates with inserting for bottle opener instrument, straight section is provided with the hypomere 30 of contiguous insertion end 24 and the epimere 32 of contiguous head end 26, wherein the horizontal section of hypomere 30 is equilateral triangle, and epimere 32 has circular horizontal section.Screw 20 is provided with a tail cutting slot 34, and tail cutting slot 34 is located at the hypomere 30 of the body of rod 22 and the segment length extended towards direction, termination 26 from insertion end 24, and the bearing of trend of tail cutting slot 34 and longitudinal axis form an included angle A, and included angle A is between 3-9 degree.
Second screw thread 38 is towards upper left to curl up extension clockwise, and the first screw thread 36 curls up extension towards upper right with counterclockwise, and the tooth of thread 2 46 is larger apart from S1 than the tooth of thread 40 1 apart from S2, and the quick spiral shell being conducive to screw 20 enters
As shown in Figure 4, screw 20 is provided with the first screw thread 36 and the second screw thread 38, first screw thread 36 is spirally located at the outside of the hypomere 30 of the body of rod 22 and is provided with multiple thread 1, and thread 1 is asymmetric thread; Thread 1 is provided with the first cutting face 42 and one second cutting face 44, and wherein the included angle B 1 of the first cutting face 42 and a horizontal axis is between 15-25 degree, and the included angle B 2 of the second cutting face 44 and horizontal axis is between 5-15 degree.Second screw thread 38 be spirally located at the epimere 32 of the body of rod 22 outside and be provided with multiple thread 2 46, second screw thread 38 on to revolve direction contrary with the first screw thread 36 revolving direction.
As shown in Figure 5, after implementing construction, insertion end 24 is locked in two objects 48,50 of plank.First screw thread 36 of the skew direction upwards extended due to tail cutting slot 34 and hypomere 30 upwards curl up direction in the same way, so when the insertion end 24 of screw 20 screws in object 48, the first screw thread 36 and tail cutting slot 34 can cutting workpieces 48 and spiral advances simultaneously; Owing to being provided with triangular section, the first screw thread 36 and object 48,50 comprehensively to contact, so can reduce the surface friction drag of advance for non-; In addition, the chip that cutting object produces will be clamp-oned in tail cutting slot 34 and holds and discharge along the outside of the hypomere 30 of triangular section, makes screw 20 lock the drag reduction in direction, thus can further improve screw-in speed; In addition, when the epimere 32 of screw 20 screws in object 48, the spiral of the second screw thread 38 advances and can produce reaming effect, the hypomere 30 of screw 20 can successfully be screwed in object 50, and make the epimere 32 of screw 20 to go deep in object 48 completely and closely, reach the object of firm connecting object 48,50; Finally, the asymmetric thread 1 of the first screw thread 36 has easily to be locked and the effect not easily exited, and can improve the combination force of screw 20.
It is more than preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
