This type of screw 900 includes a rod 91, a head 90, and a thread 92 wound on the outside of the rod 91. The thread 92 of this type of screw 900 , The pitch of each thread is the same, and when this kind of screw 900 is screwed into the workpiece 95, the rod 91 and the thread 92 are very laborious due to the friction between the workpiece 95 and the workpiece 95, especially when used in harder ones. On wooden workpieces, it is often difficult for users to lock the screw 900 into the workpiece 95 with great effort.

本發明係在提供一種省力螺絲，可以解決先前技術中，傳統螺絲在旋入工件時很費力的問題。 The invention is to provide a labor-saving screw, which can solve the problem that the traditional screw is very laborious when screwing into the workpiece in the prior art.

為使 貴審查委員能對本發明之特徵與其特點有更進一步之了解，現列舉以下較佳之實施例並配合圖式說明如下： In order to enable your reviewer to have a better understanding of the features and characteristics of the present invention, the following preferred embodiments are listed and illustrated as follows:

請參閱第1圖所示，依據本發明一較佳實施例所提供的一種省力螺絲100，包含有一桿體10及一螺紋部20。 Please refer to FIG. 1, a labor-saving screw 100 provided according to a preferred embodiment of the present invention includes a rod 10 and a threaded portion 20.

在一實施例中，該桿體10的前端具有一漸縮部11，該漸縮部11則具有一尖端12，在該桿體10的後端則具有一頭部13，在該頭部13上具有一施力槽14，該施力槽14可以採用現行的結構，例如典型的一字型或十字型。 In an embodiment, the front end of the rod 10 has a tapered portion 11, the tapered portion 11 has a tip 12, and the rear end of the rod 10 has a head 13 on the head 13 There is a force applying groove 14 on the upper part, and the force applying groove 14 can adopt an existing structure, such as a typical inline or cross shape.

在一實施例中，該螺紋部20包含有一第一螺紋21及一第二螺紋22，該第一螺紋21係圍繞在桿體10的外部表面上，該第二螺紋22係由第一螺紋21末端所延伸並螺繞在漸縮部11的外部表面上，因此，第一螺紋21及第二螺紋22係連接在一起，其中，該第一螺紋21的每一螺牙具有相同的間距a，而該第二螺紋22的每一螺牙的間距不同，且第二螺紋22的螺牙間距小於第一螺紋21的螺牙間距，實施例中，該第二螺紋22的每一螺牙間距由第一螺紋21往尖端12的方向漸減，例如，在第1圖中所示，該第一螺紋21的每一螺牙的間距為a，而該第二螺紋22的每一螺牙間距往前漸減的順序為a-n1， a-2n1，....a-yn1，其中，該第一螺紋21的間距a可以自定，該y為第二螺紋22的螺牙數，其數可以自定，n1為第二螺紋22的螺牙間距係數。 In one embodiment, the threaded portion 20 includes a first thread 21 and a second thread 22. The first thread 21 surrounds the outer surface of the rod 10, and the second thread 22 is formed by the first thread 21. The end extends and spirals on the outer surface of the tapered portion 11. Therefore, the first thread 21 and the second thread 22 are connected together, wherein each thread of the first thread 21 has the same pitch a, The pitch of each thread of the second thread 22 is different, and the pitch of the second thread 22 is smaller than the pitch of the first thread 21. In an embodiment, the pitch of each thread of the second thread 22 is The first thread 21 gradually decreases toward the tip 12. For example, as shown in Figure 1, the pitch of each thread of the first thread 21 is a, and the pitch of each thread of the second thread 22 is forward The descending order is a-n1, a-2n1,...a-yn1, where the pitch a of the first thread 21 can be customized, the y is the number of threads of the second thread 22, and the number can be customized, n1 is the second thread 22 Thread spacing coefficient.

第二螺紋22的螺牙間距係數n1的求取方式為：(y×a)-P1=(a-n1)+(a-2n1)+(a-3n1)+...(a-yn1)求得

Figure 109105441-A0305-02-0006-1
其中，P1為第二螺紋22部位的漸縮部11要縮減的長度，為自定值，而P1的值主要是考量到第二螺紋22的螺牙間距已縮小，而第二螺紋22部位的螺桿漸縮部11必然也要減短，也就是比原來具有正常螺牙間距的漸縮部要短，而要減多少的長度，可以自定。 The method of obtaining the pitch coefficient n1 of the second thread 22 is: (y×a)-P1=(a-n1)+(a-2n1)+(a-3n1)+...(a-yn1) Get
Figure 109105441-A0305-02-0006-1
Among them, P1 is the length of the tapered portion 11 of the second thread 22 to be reduced, which is a self-determined value, and the value of P1 mainly takes into account that the pitch of the second thread 22 has been reduced, and the second thread 22 The screw taper 11 must also be shortened, that is, it is shorter than the original taper with a normal thread pitch, and the length to be reduced can be customized.

以下舉一實施例做為說明： The following is an example for illustration:

設定第一螺紋21的螺牙間距a=2；設定第二螺紋22部位的漸縮部欲縮減的長度

Figure 109105441-A0305-02-0006-3
，將a=2代入前式，取得P1=1；設定第二螺紋22的螺牙數y=4；求取第二螺紋22的螺牙間距係數
Figure 109105441-A0305-02-0006-2
，其中，將P1=1，y=4代入該式中，得到n1=0.1。 Set the thread pitch of the first thread 21 a=2; set the length of the tapered portion of the second thread 22 to be reduced
Figure 109105441-A0305-02-0006-3
, Substitute a=2 into the previous formula to obtain P1=1; set the number of threads of the second thread 22 y=4; obtain the coefficient of the pitch of the second thread 22
Figure 109105441-A0305-02-0006-2
, Where, substituting P1=1 and y=4 into the formula, n1=0.1.

求取第二螺紋22的每一螺牙間距：其中第二螺紋22的螺牙數y=4，因此，第二螺紋22的螺牙間距為a-n1，a-2n1，a-3n1，a-4n1，將a=2，P1=1，n1=0.1代入前式中，得到第二螺紋22的螺牙間距往前漸減的順序為1.9，1.8， 1.7，1.6。因此，該螺絲的第一螺紋21的螺牙間距a=2，第二螺紋22具有四個螺牙數，每一螺牙間距順序為1.9，1.8，1.7，1.6。 Find the pitch of each thread of the second thread 22: the number of threads of the second thread 22 is y=4, so the pitch of the second thread 22 is a-n1, a-2n1, a-3n1, a -4n1, substituting a=2, P1=1, n1=0.1 into the previous formula, the order of the thread pitch of the second thread 22 is 1.9, 1.8, 1.7, 1.6. Therefore, the first thread 21 of the screw has a thread pitch a=2, the second thread 22 has four threads, and the sequence of each thread pitch is 1.9, 1.8, 1.7, 1.6.

上述即為本發明一較佳實施例所提供之一種省力螺絲100之各部構件及其組成方式介紹，接著再將其使用特點說明如下： The foregoing is an introduction to the various components and composition methods of a labor-saving screw 100 provided by a preferred embodiment of the present invention, and then its use characteristics are described as follows:

本發明的省力螺絲100，其結構中的第二螺紋22的螺牙間距小於第一螺紋21的螺牙間距，且第二螺紋22的每一螺牙間距往前遞減，當螺絲轉一圈時，第二螺紋22位置的直線方向移動的行程小於第一螺紋21位置的直線方向移動的行程，因此，當螺絲100在進入工件30時較為容易(請參第2圖)，且螺絲100在旋鎖入工件30時也較省力(請參第3圖)。 In the labor-saving screw 100 of the present invention, the pitch of the second thread 22 is smaller than the pitch of the first thread 21, and the pitch of each thread of the second thread 22 decreases forward, when the screw rotates one turn The linear movement stroke of the second thread 22 position is less than the linear movement stroke of the first thread 21 position. Therefore, it is easier when the screw 100 enters the workpiece 30 (please refer to Figure 2), and the screw 100 is rotating It also saves effort when locking the workpiece 30 (please refer to Figure 3).

以上所揭，僅為本發明所提供之較佳實施例而已，並非用以限制本發明之實施範圍，凡本技術領域內之相關技藝者根據本發明所為之均等變化，皆應屬本發明所涵蓋之範圍。 The above disclosures are only the preferred embodiments provided by the present invention, and are not intended to limit the scope of implementation of the present invention.
