    • A composite drill bit with a bit body configured at its upper extend for connection into a drillstring, comprising: a bit body (1) with at least one bit leg (3), at least one scraping-wheel (2) set with a cutter-row (4), and a set of cutters fixed thereon. The scraping-wheel (2) is mounted for rotation on the corresponding bit leg (3) with a large angular deflection α in the range of 20°≦|α|≦90°. The cutters on the scraping-wheel break rock by means of successive scraping, forming a cross-cutting area on the bottomhole accompanied by the cutters on the fixed cutting unit, thus achieving high rock-breaking efficiency, even wear, high cooling performance, and a longer service life for the cutters, bearings and the drill bit.

    • A cutting mat comprises: a baseboard defined with an assembling hole and at least one notch on a side of the assembling hole, a positioning member detachably disposed in the assembling hole, and a cutting board. The positioning member includes a circular body and at least one positioning protrusion formed on a side of the circular body and located in a corresponding position to the notch of the baseboard. The cutting board is formed at the bottom thereof with a circular recess for engaging the circular body of the positioning member, so that the cutting board is rotatably superposed on the baseboard. When the positioning member is inversely disposed with the positioning protrusion being protruded from the top surface of the baseboard, and the circular body and the positioning protrusion are partially received in the assembling hole and the notch of the baseboard, the circular recess and the positioning notch of the cutting board will be engaged with the positioning member and a part of the positioning protrusions; as a result, the cutting board is unrotatably positioned on the baseboard.
    • 切割垫包括:限定有组装孔的基座和在组装孔的一侧上的至少一个切口,可拆卸地设置在组装孔中的定位构件和切割板。 定位构件包括圆形体和形成在圆形体的侧面上的至少一个定位突起,并且位于与基板的凹口相对应的位置。 切割板在其底部形成有用于接合定位构件的圆形体的圆形凹部,使得切割板可旋转地重叠在基板上。 当定位构件相反地设置有定位突起从基板的顶表面突出时,并且圆形体和定位突起部分地容纳在基板的组装孔和凹口中,圆形凹槽和定位凹口 的切割板将与定位构件和定位突起的一部分接合; 结果,切割板不能旋转地定位在基板上。

    • A collapsible spiral-tube escape way includes a plurality of spiral-tube units supported on tube-supporting frames. In a first embodiment of the escape way, the tube-supporting frames in a standby position are elevated and collapsed to sit on a crane mounted on a roof of a building. In an emergency, the whole escape way is vertically lowered to locate in front of and connect to exits of the building, so that users may easily enter into the spiral-tube units via the exits at different floors and slide all the way down to the ground. In a second embodiment, the tube-supporting frames in the standby position are separately pivotally lifted to flatly attach to the exterior wall of the building outside the exits. In an emergency, users need only to open the exits and the tube-supporting frames automatically tilt down to a horizontal position to pull open the spiral-tube units for use.
    • 可折叠的螺旋管逃逸方式包括支撑在管支撑框架上的多个螺旋管单元。 在逃生方式的第一实施例中,备用位置的管支撑架被升高并折叠以坐在安装在建筑物屋顶上的起重机上。 在紧急情况下,整个逃生方式垂直降低,位于建筑物前面并连接到建筑物的出口处,使用户可以通过不同楼层的出口轻松进入螺旋管单元,并一直向下滑动到 地面。 在第二实施例中,处于备用位置的管支撑框架分别枢转地提升以平坦地附接到出口外部的建筑物的外壁。 在紧急情况下,用户只需要打开出口,并且管支撑框架自动向下倾斜到水平位置,以拉开螺旋管单元以供使用。

    • An adjustable rotary structure comprises a first restricting assembly, a second restricting assembly, a rotary member and a positioning seat. The rotary member is formed with a restricting hole and a shift hole. The positioning seat is formed with a positioning groove, a restricting circular groove and a restricting elliptic groove. The first restricting assembly is positioned on the positioning groove by the restricting hole in such a manner that the restricting hole of the rotary member abuts against the positioning groove and is restricted on the positioning seat. The second restricting assembly is selectively positioned in the restricting circular groove or the restricting elliptic groove via the shift hole, so that the rotary member is forced to rotate along a circular path or an elliptic path.
    • 可调节的旋转结构包括第一限制组件,第二限制组件,旋转构件和定位座。 旋转构件形成有限制孔和换档孔。 定位座形成有定位槽,限制圆形槽和限制椭圆槽。 第一限制组件通过限制孔定位在定位槽上,使得旋转构件的限制孔抵靠定位槽并限制在定位座上。 第二限制组件通过移动孔选择性地定位在限制圆形槽或限制椭圆形槽中,使得旋转构件被迫沿着圆形路径或椭圆形路径旋转。
