是以，上述即為本創作一較佳實施例所提供複合式量測裝置1之各部構件及其組合方式之介紹，接著再將其使用特點介紹如下：
當欲由本創作對一實心圓桿901進行真圓度之量測以判別其真直度時，如第十圖至第十二圖所示。首先，將該實心圓桿901一端之圓心頂掣在該第二支撐器200之第二尖部622上（如第十圖所示），並扳動該第一支撐器100之扳桿57，使由該從動件56扳動該受力軸54而壓縮該彈簧55，而由該受力軸54帶動該第一柱套51與第一頂柱52往內縮回（如第十圖所示），接著再釋放該扳桿57，使由該彈簧55回復之彈力帶動該受力軸54、第一柱套51及第一頂柱52向外位移，以將該第一頂柱52之第一尖部522推出於該第一基座10之前端外，進而頂掣在該實心圓桿901另一端之圓心上（如第十一圖所示）。如此一來，便能將一量錶904接觸於該實心圓桿901之表面上（如第十二圖所示），並旋轉該實心圓桿901以量測出真圓度，及水平軸向地移動該量錶904以量測實心圓桿901其它位置之真圓度，藉此以判別實心圓桿901之真直度。
另外，當欲由本創作對一同一外徑之空心圓管902進行真圓度與真直度之量測時，如第十三圖至第十六圖所示。首先，如欲量測之空心圓管902之管徑較大時，可將該第一轉座30及第二轉座40上之第一定位螺栓34與第二定位螺栓44稍加旋鬆，使該第一定位螺栓34與該第二定位螺栓44分別脫離該第一鎖孔314與該第二鎖孔414，而能轉動該第一轉盤32與該第二轉盤42，使由較大尺寸之第一軸承組33與較大尺寸之第二軸承組43朝上，再重新將該第一定位螺栓34與該第二定位螺栓44分別伸入於該第一鎖孔314與該第二鎖孔414內。如此一來，便能由較大尺寸之第一軸承組33與第二軸承組43共同供較大管徑之空心圓管902進行承靠（如第十三圖及第十四圖所示），以利進行空心圓管902各個位置之真圓度以判別空心圓管之真直度。當欲量測之空心圓管902之管徑較小時，則依相同方法旋轉該第一轉盤32與該第二轉盤42，使由較小尺寸之第一軸承組33與較小尺寸之第二軸承組43朝上，以利供較小管徑之空心圓管902承靠（如第十五圖及第十六圖所示）。
其次，於本創作中，該第一定位螺栓34前端為受一第一彈簧341所頂推之第一鋼珠342，與該第二定位螺栓44前端為受一第二彈簧441所頂推之第二鋼珠442（如第十四圖至第十七圖所示）。藉此，當該第一轉盤32及第二轉盤42做轉動調整時，係先將該第一定位螺栓34及該第二定位螺栓44稍微調鬆，使該第一轉盤32及第二轉盤42在轉動時，該第一定位螺栓34及第二定位螺栓44的第一、二鋼珠342、442會受壓迫而內縮，當轉至第一鎖孔314及第二鎖孔414時，該第一、二鋼珠342、442會分別被第一、二彈簧341、441推出而抵壓於第一鎖孔314及第二鎖孔414中。如此一來，操作者便能確定已調整至所欲到達的位置，然後再令第一定位螺栓34及第二定位螺栓44更朝第一鎖孔314及第二鎖孔414中鎖入而使第一定位螺栓34及第二定位螺栓44之底端直接抵壓於第一鎖孔314及第二鎖孔414，而該各第一、二鋼珠342、442則會稍微內縮至第一定位螺栓34及第二定位螺栓44中。以達到操作便利及輕易定位之功效。
接著，當欲由本創作對一具有不同外徑之空心圓管903進行真圓度與真直度之量測時，先將該第一支撐器100上之第一轉盤32進行旋轉，以將較大尺寸之第一軸承組33朝上，並將該第二支撐器200上之第二轉盤42進行旋轉，以將較小尺寸之第二軸承組43朝上（如第十七圖所示）。然後，將該空心圓管903較大外徑之一端放置在該第一軸承組33上，再旋轉該升降調整單元23之驅動盤233，以由該驅動盤233帶動該螺桿231旋轉，而利由該外螺紋身部236與該調整螺孔212之螺接，及該導引柱211與該導引孔之導引，而使該螺桿231在旋轉之同時，能帶動該第二座體21進行上下之升降（如第十八圖所示），直至讓該空心圓管903較小外徑之一端能放置在該第二軸承組43上，並保持在水平狀態為止。藉此，便能達到對具有不同外徑之空心圓管903進行不同位置之真圓度量測，以判別空心圓管903之真直度。
是以，本創作不僅能對具有不同外徑之空心圓管進行真圓度與真直度之量測，並能對單一外徑之空心圓管及實心圓桿進行真圓度與真直度之量測，而讓使用範圍更加廣泛、便利性更佳，以減少使用者之支出。
另外，雖然上述實施例中，該第一支撐器100與該第二支撐器200係固定在檯面90上。但，實際上，該檯面90可具有至少一滑軌91（如第九圖所示）；該第一支撐器100之第一基座10更具有至少一第一滑塊13（如第六圖所示），該第一滑塊13係固接於該第一座體11之底面，並與該滑軌91滑接，而可受外力作用於該滑軌91上進行往復之直線位移；該第二支撐器200之第二基座20更具有至少一第二滑塊24（如第八圖所示），該第二滑塊24係固接於該底座22之底面，並與該滑軌91滑接，而可受外力作用於該滑軌91上進行往復之直線位移。藉此，可輕易地滑動該第一支撐器100與該第二支撐器200，使該第一支撐器100與該第二支撐器200間之距離得以輕易調整，以利適用不同長度之被量測物。
以上所揭，僅為本創作所提供之較佳實施例而已，並非用以限制本創作之實施範圍，凡本技術領域內之相關技藝者根據本創作所為之均等變化，皆應屬本創作所涵蓋之範圍。

Therefore, the above is an introduction to the various components and their combinations of the composite measuring device 1 provided by a preferred embodiment of this creation, and then the characteristics of its use are introduced as follows:
When it is desired to measure the roundness of a solid round rod 901 by this creation to determine its straightness, as shown in the tenth to twelfth figures. First, pin the center of one end of the solid round rod 901 on the second tip 622 of the second support 200 (as shown in the tenth figure), and pull the lever 57 of the first support 100, The driven member 56 pulls the force shaft 54 to compress the spring 55, and the force shaft 54 drives the first column sleeve 51 and the first top column 52 to retract inward (as shown in the tenth figure). Show), and then release the lever 57, so that the elastic force restored by the spring 55 drives the force-bearing shaft 54, the first column sleeve 51 and the first top column 52 to move outwards, so that the first top column 52 The first tip 522 is pushed out of the front end of the first base 10, and then is pressed on the center of the other end of the solid round rod 901 (as shown in the eleventh figure). In this way, a gauge 904 can be contacted on the surface of the solid round rod 901 (as shown in Figure 12), and the solid round rod 901 can be rotated to measure the roundness and horizontal axis The scale 904 is moved to measure the roundness of other positions of the solid round rod 901, so as to determine the true straightness of the solid round rod 901.
In addition, when the roundness and straightness of a hollow tube 902 of the same outer diameter are to be measured by this creation, as shown in the thirteenth to sixteenth figures. First, if the diameter of the hollow tube 902 to be measured is relatively large, the first positioning bolt 34 and the second positioning bolt 44 on the first rotating seat 30 and the second rotating seat 40 can be slightly loosened. The first positioning bolt 34 and the second positioning bolt 44 are separated from the first locking hole 314 and the second locking hole 414, respectively, so that the first turntable 32 and the second turntable 42 can be rotated to make the larger size The first bearing set 33 and the larger-sized second bearing set 43 face upwards, and then the first positioning bolt 34 and the second positioning bolt 44 are extended into the first lock hole 314 and the second lock, respectively. Inside the hole 414. In this way, the larger-sized first bearing set 33 and the second bearing set 43 can jointly support the hollow round tube 902 with a larger pipe diameter (as shown in Figures 13 and 14) , In order to facilitate the roundness of each position of the hollow circular tube 902 to determine the straightness of the hollow circular tube. When the diameter of the hollow tube 902 to be measured is small, the first turntable 32 and the second turntable 42 are rotated in the same way, so that the smaller-sized first bearing set 33 and the smaller-sized second The second bearing set 43 faces upwards to facilitate the support of the hollow round tube 902 with a smaller diameter (as shown in the fifteenth and sixteenth figures).
Secondly, in this creation, the front end of the first positioning bolt 34 is a first steel ball 342 pushed by a first spring 341, and the front end of the second positioning bolt 44 is a first steel ball pushed by a second spring 441. Two steel balls 442 (as shown in Figures 14 to 17). Therefore, when the first turntable 32 and the second turntable 42 are rotated and adjusted, the first positioning bolt 34 and the second positioning bolt 44 are slightly loosened to make the first turntable 32 and the second turntable 42 When rotating, the first and second steel balls 342, 442 of the first positioning bolt 34 and the second positioning bolt 44 will be compressed and contracted. The first and second steel balls 342 and 442 are respectively pushed out by the first and second springs 341 and 441 to be pressed into the first lock hole 314 and the second lock hole 414. In this way, the operator can confirm that the position has been adjusted to the desired position, and then the first positioning bolt 34 and the second positioning bolt 44 are locked into the first locking hole 314 and the second locking hole 414. The bottom ends of the first positioning bolt 34 and the second positioning bolt 44 directly press against the first locking hole 314 and the second locking hole 414, and the first and second steel balls 342, 442 are slightly retracted to the first positioning Bolt 34 and the second positioning bolt 44. In order to achieve the effect of convenient operation and easy positioning.
Then, when it is desired to measure the roundness and straightness of a hollow tube 903 with different outer diameters by this creation, first rotate the first turntable 32 on the first support 100 to remove the larger The first bearing set 33 of the size faces upwards, and the second turntable 42 on the second support 200 is rotated to turn the second bearing set 43 of the smaller size upwards (as shown in Figure 17). Then, one end of the larger outer diameter of the hollow tube 903 is placed on the first bearing set 33, and then the driving disc 233 of the lifting adjustment unit 23 is rotated, so that the driving disc 233 drives the screw 231 to rotate, which is advantageous By the screw connection of the external threaded body 236 and the adjusting screw hole 212, and the guiding of the guide post 211 and the guide hole, the screw 231 can drive the second seat body 21 while rotating Lift up and down (as shown in the eighteenth figure) until one end of the smaller outer diameter of the hollow tube 903 can be placed on the second bearing set 43 and kept in a horizontal state. In this way, it is possible to measure the true circle of the hollow tube 903 with different outer diameters at different positions to determine the straightness of the hollow tube 903.
Therefore, this creation can not only measure the roundness and straightness of hollow tubes with different outer diameters, but also measure the roundness and straightness of hollow tubes and solid rods with a single outer diameter. It can be used in a wider range and more convenient, so as to reduce the user’s expenditure.
In addition, although in the above embodiment, the first supporter 100 and the second supporter 200 are fixed on the table 90. However, in fact, the table 90 may have at least one sliding rail 91 (as shown in the ninth figure); the first base 10 of the first support 100 further has at least one first sliding block 13 (as shown in the sixth figure). (Shown), the first sliding block 13 is fixedly connected to the bottom surface of the first base 11 and slidably connected to the sliding rail 91, and can be subjected to external force to act on the sliding rail 91 for reciprocating linear displacement; the The second base 20 of the second support 200 further has at least one second sliding block 24 (as shown in the eighth figure). The second sliding block 24 is fixedly connected to the bottom surface of the base 22 and is connected to the sliding rail. 91 is slidingly connected, and can be subjected to external force on the sliding rail 91 for reciprocating linear displacement. Thereby, the first supporter 100 and the second supporter 200 can be easily slid, so that the distance between the first supporter 100 and the second supporter 200 can be easily adjusted, so as to be suitable for quilts of different lengths. Measured object.
