如此提供2種不同尺寸的螺帽使用的結構，為求施工的方便，通常會以提供連續尺寸螺帽為其套筒設計，亦即該套筒會以9mm、11mm或11mm、13mm或13mm、15mm或15mm、17mm…等等連續級距尺寸設計，當外套筒1的第一內六角套合段13(HEX1)的內徑為15mm時，該內套筒2的第二內六角套合段21(HEX2)的內徑則為13mm，所以，該內套筒2的壁厚T厚度取決於內套筒2的第二內六角套合段21(HEX2)的內徑與外套筒1的第一內六角套合段13(HEX1)的內徑的尺寸差距，亦即T=HEX1-HEX2，所以，此時內套筒2的單邊壁厚T為(HEX1-HEX2)÷2=1mm，如此1mm的壁 厚T為承受內套筒2受力時的扭力，顯然不足，而容易產生變形的情況，而為使其達到承受扭力且不致產生變形所需的強度，所以需使內套筒組2具有比如2mm的壁厚T，使得該套筒僅可提供諸如13mm、17mm或15mm、19mm…等不連續尺寸級距的套筒，而無法提供連續尺寸級距的套筒，使得使用者無法大約判斷螺帽的尺寸(如13mm或15mm)，即可拿取連續級距尺寸13-15mm的套筒使用，而需正確判斷螺帽的尺寸約為13mm或15mm後，再找到有正確尺寸的套筒始可動作，因而增加工作上的困擾。 The structure for providing two different sizes of nuts is provided for the convenience of construction, and the sleeve is usually designed with a continuous size nut, that is, the sleeve will be 9mm, 11mm or 11mm, 13mm or 13mm, 15mm or 15mm, 17mm, etc. continuous step size design, when the inner diameter of the first inner hexagonal sleeve 13 (HEX1) of the outer sleeve 1 is 15mm, the second inner hexagon sleeve of the inner sleeve 2 The inner diameter of the segment 21 (HEX2) is 13 mm, so the thickness T of the inner sleeve 2 depends on the inner diameter of the second inner hexagonal sleeve 21 (HEX2) of the inner sleeve 2 and the outer sleeve 1 The difference in the inner diameter of the first hexagonal ferrule 13 (HEX1), that is, T=HEX1-HEX2, so that the single-wall thickness T of the inner sleeve 2 is (HEX1-HEX2) ÷ 2= 1mm, such a 1mm wall The thickness T is a torsion force when the inner sleeve 2 is subjected to a force, which is obviously insufficient, and is easily deformed, and in order to achieve the strength required to withstand the torsion without causing deformation, it is necessary to make the inner sleeve group 2 have The wall thickness T of 2mm makes the sleeve only provide a sleeve of discontinuous size such as 13mm, 17mm or 15mm, 19mm..., and cannot provide a sleeve of continuous size step, so that the user cannot judge the snail. Cap size (such as 13mm or 15mm), you can take the sleeve with a continuous step size of 13-15mm, and you need to correctly judge the size of the nut is about 13mm or 15mm, then find the sleeve with the correct size It can move, thus increasing the trouble of work.

再請參閱第八圖所示，其係為其實施示意一，該內套筒2內亦可套設一第二內套筒3或更多的活動套筒，但使該套筒可提供3種或3種不同但連續尺寸的螺帽使用，但相同的其壁厚T的厚度顯然不足，而容易產生變形的情況。 Referring to FIG. 8 again, it is shown in FIG. 1 that the inner sleeve 2 can also be sleeved with a second inner sleeve 3 or more movable sleeves, but the sleeve can provide 3 Kinds or three different but continuous size nuts are used, but the same thickness of the wall thickness T is obviously insufficient, and deformation is likely to occur.

本套筒的優點是在於： The advantages of this sleeve are:

(1)藉由第一活動套筒的限位座套合限位於外套筒的限位槽，當外套筒的施力座(HEX3)的內徑為與習用第一內六角套合段(HEX1)同為15mm時，該第一活動套筒的施力面(HEX4)的內徑與習用第二內六角套合段(HEX2)相同為13mm時，此時，該第一活動套筒的壁厚T為厚度為取決於施力座(HEX3)的內徑與施力面(HEX4)的內徑差(與習用者相同的1mm)加上限位座(T1)的厚度，亦即T=HEX3-HEX4+T1，如此，第一活動套筒的壁厚T與習用者相較厚度增加了T1的厚度，如此即增加了第一活動套筒的施力強 度。 (1) The limit sleeve of the first movable sleeve is limited to the limit groove of the outer sleeve, and the inner diameter of the outer sleeve of the outer sleeve (HEX3) is the same as the conventional first hexagon socket (HEX1) When the same size is 15mm, the inner diameter of the force applying surface (HEX4) of the first movable sleeve is the same as the conventional second hexagonal socket (HEX2) of 13mm, at this time, the first movable sleeve The thickness T of the wall is determined by the thickness of the inner diameter of the force applying seat (HEX3) and the inner diameter of the force applying surface (HEX4) (the same 1 mm as the conventional one) plus the thickness of the upper seat (T1), that is, T =HEX3-HEX4+T1, such that the wall thickness T of the first movable sleeve increases the thickness of T1 compared with the conventional one, thus increasing the force of the first movable sleeve degree.

(2)藉由第一活動套筒的限位座套合限位於外套筒的限位槽，當此時T1的厚度足以支撐活動套筒的受力，使原本為13mm才可夠支撐厚度的的施力面(HEX4)，可縮小其與施力座(HEX3)間的差距，亦即原本為13mm的施力面(HEX4)可做為13.5mm、14mm或14.5mm…的尺寸，以符合多重尺寸變化的套筒使用者。 (2) The limit seat sleeve of the first movable sleeve is limited to the limit groove of the outer sleeve. When the thickness of the T1 is sufficient to support the force of the movable sleeve, the original thickness of 13 mm can support the thickness. The force-applying surface (HEX4) can reduce the gap between it and the force-applying seat (HEX3), that is, the original force-applying surface (HEX4) can be made into the size of 13.5mm, 14mm or 14.5mm... A sleeve user that meets multiple dimensional changes.

(3)藉由第一活動套筒的限位座套合限位於外套筒的限位槽，可縮小施力面(HEX4)與施力座(HEX3)間至些微的差距，亦即當施力座(HEX3)為15mm，而施力面(HEX4)可為9/16〞，以提供一為公制一為英制，且尺寸差距微小的二種尺寸套筒的使用，且該施力面(HEX4)可受限位座的支撐，而無損壞之虞。 (3) By limiting the limit sleeve of the first movable sleeve to the limit groove of the outer sleeve, the slight difference between the force applying surface (HEX4) and the force applying seat (HEX3) can be reduced, that is, when The force-applied seat (HEX3) is 15mm, and the force-applying surface (HEX4) can be 9/16〞, to provide a two-size sleeve that is metric and has a small size difference, and the force-applying surface ( HEX4) can support the limited seat without damage.
