Problems solved by technology

[0003] However, after use, it is found that the screw 1 of the prior art can only use the locking part 13 to enter the lock 2 in a gradual and squeezed manner during the locking process, until the thread 14 continues the locking Part 13 enters the lock 2, so that the thread 13 can be screwed into the locking action. Therefore, during the relocking process, only the thread 14 can be used to cut the fibers of the lock 2 As a result, at the initial stage of locking, the locking part 13 is still subjected to the subsequent screw-in action driven by the screw head 11 to squeeze the lock 2, so not only the lock cannot be effectively locked. The fibers of the object 2 are cut off, and at the same time, the fibers of the object 2 will be wound on the rod body 12, thereby greatly increasing the locking torque, which will not only affect the actual locking efficiency, but also cause the chips generated by the subsequent screwing to fail. It is easy to discharge outward through the chip removal groove 141 formed between the screw teeth 14, so that the chips are easy to accumulate in the lock 2, if the screw 1 continues to be driven by the tool and the lock If the lock 2 produces a twist-lock effect, it will not only be relatively labor-intensive, but also cause too many chips in the lock 2 to form a compression phenomenon inside the lock 2, which will easily cause the lock 2 to have The lack of cracked wood occurs, and it needs to be improved

Embodiment Construction

[0053] The foregoing and other technical contents, features and effects of the present invention will be clearly understood in the following detailed description of preferred embodiments with reference to the drawings.

[0054] refer to figure 2 , the first preferred embodiment of the present invention, the screw 3 includes a screw head 31, a rod body 32 extending outwards from the screw head 31, a lock opposite to the screw head 31 and formed at the other end of the rod body 32 part 33, a helical ring set on the rod body 32 and a first thread 34 extending from the screw head 31 to the lock part 33, and a screw ring set on the rod body 32 near the lock part 33 and toward The guide tooth 35 extending in the direction of the screw head 31, and one end of the aforementioned first thread 34 and the corresponding end of the guide tooth 35 are not in contact with each other, so that the first thread 34 and the guide tooth 35 are not in contact with each other. A toothless section ...

Abstract

The present invention provides a screw, which mainly forms a threadless section between the first thread and the guide tooth of the rod body, and at the same time, a threadless section is provided at the threadless section, which is respectively connected to the first thread and the guide tooth. The cutting edge connected with the end, so that when the locking operation is performed, the guide tooth can be used to assist the locking part to lock and enter, and then the toothless section can be used to accommodate the chips generated during the locking process, and the cutting edge It can also assist in chopping the uncut wood fiber during the entry process of the twistlock, which can effectively reduce the locking resistance and accelerate the improvement of locking efficiency.

Description

technical field [0001] The invention relates to a screw design, in particular to a screw that accelerates and improves locking efficiency. Background technique [0002] refer to figure 1 , the screw 1 of the prior art includes a screw head 11, a rod body 12 extending outward from the screw head 11, a locking portion 13 opposite the screw head 11 and formed at the other end of the rod body 12, and a helical ring The thread 14 provided on the rod body 12; therefore, when performing the locking operation, a tool (not shown) can be used to drive the screw head 11 to drill into a lock 2, and at the same time the screw The teeth 14 will continue to be screwed into the lock 13 together with the guide of the lock part 13 when the lock part 13 is driven by the rotation of the tool, thereby achieving the effect of locking and positioning. [0003] However, after use, it is found that the screw 1 of the prior art can only use the locking part 13 to enter the lock 2 in a gradual and s...
