Detailed Description

In order that those skilled in the art will better understand the technical solutions of the present utility model, preferred embodiments of the present utility model will be described below with reference to specific examples, but it should be understood that these descriptions are only for further illustrating the features and advantages of the present utility model, and are not limiting the patent claims of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model will be further described with reference to the drawings and preferred embodiments.

Example 1

Referring to fig. 1 to 4, an easy-to-attack wood screw according to this embodiment includes a screw head 1 and a screw shaft 2, the screw head 1 is disposed at one end of the screw shaft 2, the other end of the screw shaft 2 has a self-tapping drill 3, and further includes at least one pin hole 4 penetrating the screw head 1 and the screw shaft 2, a pin 5 is inserted into the pin hole 4, the length of the pin 5 is greater than the depth of the pin hole 4, the pin hole 4 has a first hole (not labeled in the drawing) disposed at the screw head 1, a second hole (not labeled in the drawing) disposed at the screw shaft 2, and one end of the pin 5 extends out of the first hole.

Further, the pin 5 is a hollow pin, and an opening 6 for communicating the inside and the outside is formed in the side surface of the pin 5.

Further, a rotating groove 7 is formed on the end face of the screw head 1, and the first orifice is arranged outside the rotating groove 7.

Further, the axis of the pin hole 4 is parallel to the axis of the screw shaft 2, and the second hole is formed in the self-tapping drill.

Example 2

Further, the axis of the pin hole 4 forms an included angle with the axis of the screw rod part 2 in the range of 5-15 degrees, and the second orifice is arranged on the screw rod part 2.

In this embodiment, the wood screw is screwed into the wood screw to realize the function of connecting two wood pieces, and then the hammering tool is taken to hammer the pin 5 exposing the screw head 1, so that the pin 5 slides in the interference fit state in the pin hole 4, the hammered end of the pin 5 extends out of the second hole and is inserted into the wood, and the screw rod 2 is limited to reversely rotate, so that the connected screw cannot be dismounted.

The pin 5 is provided with the opening 6 on the side surface by arranging the pin 5 as a hollow pin, so that the pin 5 has moderate elasticity along the radial direction and can be clamped in the pin hole 4 in a static state, and the sliding in the pin hole 4 is easier to finish when the pin is impacted axially; the machining precision of the pin 5 is also indirectly reduced due to the existence of the elastic allowance, and the machining and the assembly are more facilitated.

The easy-to-attack wood screw cannot be disassembled secondarily after fastening and connection are completed, is compact in connection, safe and reliable to use, complete in overall function and high in practicability.
