The tool joint 10 includes a support rod 11, a working head 12 and a limiting structure 13, which One end of the support rod 11 is provided with a polygonal spherical head 111 and an annular side 112, and the other end is provided with a driving portion 113 for connecting the driving device. A hole is radially opened at a maximum diameter of the polygonal spherical head 111 for loading. The abutting member 114 is pushed up by the elastic member so that the abutting member 114 can move toward the opening of the hole at any time; the working head 12 has a polygonal receiving groove 121 at one end and the other end. The mounting tool is provided with a limiting groove 122 and an annular groove 123 at a suitable position in the receiving groove 121, and a ring-shaped yoke which can be engaged with the annular side 112 of the support rod 11 is provided at the opening of the receiving groove 121. The top edge 124, after the polygonal spherical head 111 of the support rod 11 is fitted into the receiving groove 121 of the working head 12, is supported by the limiting structure 13 disposed in the annular groove 123. The polygonal spherical head 111 of the strut 11 is limited to the receiving groove 121 of the working head 12, and the polygonal spherical head 111 of the supporting rod 11 is movable between the first position and the second position; please refer to FIG. 2 When the support rod 11 is pressed down to be in the first position, since the annular edge 112 of the support rod 11 is fitted to the annular abutting edge 124 of the working head 12, the support rod 11 and the working head 12 are linearly connected to facilitate driving. The device directly drives the operation; as shown in Fig. 3, when the support rod 11 is slightly pulled out and is in the second position, since the annular edge 112 of the support rod 11 is separated from the annular abutment edge 124 of the working head 12, the support rod is 11 can use the polygonal ball head 111 as a pivot point to pivot the operating angle with respect to the working head 12, and can be operated in a space-constrained condition; however, the tool joint 10 still has the following disadvantages in use:
1．該工具接頭10為因應不同的帶動操作方式，必須繁瑣的將支撐桿11下壓至第一位置或拉出至第二位置，而此須透過下壓或拉出支撐桿11位移至第一位置或第二位置，才能夠選擇所需操作模式的方式，於操作上相當不方便。 1. The tool joint 10 is cumbersome to press the support rod 11 to the first position or to the second position in response to different driving operations, and this must be displaced to the first position by pressing down or pulling out the support rod 11. Or the second position, the way to select the desired mode of operation is quite inconvenient in operation.
2．該工具接頭10之支撐桿11位於第一位置時，其雖可利用支撐桿11之環形邊112套合於作業頭12之環形抵頂緣124，以限制支撐桿11與作業頭12作直線銜接，然而，當工具接頭10之支撐桿11位於第二位置，使支撐桿11與作業頭12樞擺一操作角度使用時，由於支撐桿11與作業頭12間並無穩固的定位作用，而於操作過程中，只要稍加施力，該支撐桿11極易縮入位移至第一位置，使支撐桿11之環形邊112套合於作業頭12之環形抵頂緣124，而限制樞擺操作角度的作用，當以氣動工具驅動作業頭12而帶動支撐桿11高速旋轉時，一旦發生支撐桿11由第一位置縮入位移至第二位置而限制樞擺操作角度的情況下，將可能對使用者產生 極大的危險，而於使用安全性上造成相當大的隱憂。 2. When the support rod 11 of the tool joint 10 is in the first position, the annular edge 112 of the support rod 11 can be fitted to the annular abutment edge 124 of the working head 12 to limit the straight connection between the support rod 11 and the working head 12. However, when the support rod 11 of the tool joint 10 is in the second position, when the support rod 11 is pivoted at an operating angle with the working head 12, since there is no stable positioning between the support rod 11 and the working head 12, During operation, the support rod 11 is easily retracted into the first position by a slight application of force, so that the annular edge 112 of the support rod 11 fits over the annular abutment edge 124 of the working head 12, and the pivoting operation is restricted. The role of the angle, when the working head 12 is driven by the pneumatic tool to drive the support rod 11 to rotate at a high speed, once the support rod 11 is retracted from the first position to the second position to limit the pivoting operation angle, it may be User generated There is a great danger, and there is considerable concern about the safety of use.
