In an embodiment of the utility model, as shown in fig. 1-3, provide a five-claw nail, including body 10, body 10 is the cylinder structure, body 10 has relative first end 11 and the second end 12 that sets up, body 10 is provided with and runs through the screw hole 13 of first end 11 and second end 12, the lateral wall of first end 11 is provided with and is used for spacing annular arch 14, a plurality of sand grips 15 have evenly been arranged along its axial direction to the lateral surface of body 10, the one end of sand grip 15 extends to annular arch 14.

Specifically, the during operation, drill the plank, make the plank have the through-hole that is used for installing five-jaw nail, then go into this through-hole with five-jaw nail card, when going into, each sand grip 15 respectively with the lateral wall butt of through-hole, thereby make five-jaw nail chucking in the through-hole, then when fixing another plank and this plank, pass the bolt behind the through-hole of another plank with screw hole 13 threaded connection, the nut of bolt and the protruding 14 cooperation of annular with two plank fixed connection, because sand grip 15 is connected with the lateral wall close-fitting of through-hole, make at five-jaw nail with bolted connection in-process, this through-hole of five-jaw nail relatively is quiescent condition, thereby can improve the gripping power of five-jaw nail in the through-hole, and can not injure the surface of plank, moreover, the steam generator is simple in structure, easy production.

In another embodiment of the present invention, as shown in fig. 1 to 3, the end of the protruding strip 15 facing the second end 12 is provided with a slope. Specifically, sand grip 15 is provided with the inclined plane, and the contact surface between and the mould is bigger in production to when making into sand grip 15 shaping, pressure is less, can rapid prototyping, the degree of difficulty of reduction production.

In another embodiment of the present invention, as shown in fig. 1 to 3, the body 10 includes a fixing portion 16 and a guiding portion 17, the second end 12 is a free end of the guiding portion 17, and the diameter of the fixing portion 16 is larger than that of the guiding portion 17. Specifically, the five-jaw nail is inserted into the through hole of the wood board, and since the diameter of the guide portion 17 is smaller than that of the fixing portion 16, the guide portion 17 plays a role of guiding when inserted into the through hole so that the axial direction of the threaded hole 13 overlaps with the axis of the through hole.

In another embodiment of the present invention, as shown in fig. 1 to 3, an end of the protruding strip 15 facing away from the annular protrusion 14 extends to a joint of the fixing portion 16 and the guiding portion 17. Specifically, when the guide portion 17 is completely inserted into the through hole, each of the ribs 15 is again interference-fitted with the through hole, so that the axial direction of the threaded hole 13 can be further overlapped with the axis of the through hole.

In another embodiment of the present invention, as shown in fig. 1 to 3, a reinforcing rib 18 is disposed between the annular protrusion 14 and the sidewall of the body 10. Specifically, the reinforcing ribs 18 are arranged, so that the strength of the annular protrusion 14 and the side wall of the body 10 is increased, the annular protrusion 14 is not easy to deform when a wood board is fixed, and the stability of the fixed wood board is improved.

In another embodiment of the present invention, as shown in fig. 1 to 3, one end of the bar-shaped protrusion extends to the reinforcing rib 18. In this way, the whole fixing portion 16 and the through hole are kept in interference fit, and the connection stability is improved.

In another embodiment of the present invention, as shown in fig. 1 to 3, the number of the protruding strips 15 is five. Set up five sand grips 15 and can satisfy the condition of fastening, simultaneously, can be convenient for insert five claw nails to the through-hole in.

In another embodiment of the present invention, as shown in fig. 1 to 3, the cross section of each protruding strip 15 is a triangular structure. Specifically, the convex strip 15 of the triangular structure has stronger stability, and when the convex strip is in interference fit with the through hole, the convex strip abuts against the side wall of the through hole, so that the fastening performance of the interference fit is improved.

In another embodiment of the present invention, as shown in fig. 1 to 3, the second end 12 is provided with a chamfer. Thus, when the guide portion 17 is inserted into the through hole, the insertion can be performed quickly, and the interference can be avoided.

In another embodiment of the present invention, as shown in fig. 1 to 3, the five-claw nail is an integrally formed structure, and specifically, the five-claw nail is produced by extrusion forming, and extrusion forming is adopted to improve the efficiency of producing the five-claw nail, thereby improving the competitiveness of enterprises.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
