An apparatus for controlling the direction of drill bit within a wellbore. The apparatus comprises a first housing with a first housing axis therein, and wherein the first housing has a first threaded opening having a first threaded opening axis. The first housing has a helical end. A second housing is included, and the second housing contains a second housing axis, and a second threaded opening having a second threaded opening axis configured to engage with the first threaded opening. A collar is included that has a helical collar end that engages the helical collar end and wherein the helical collar end is configured reciprocal to the helical end, and rotational displacement of the first housing relative to the collar will angularly displace the drill bit axis. The apparatus may further include spline members for locking the collar in place relative to the first and second housing.

The invention discloses a mineral exploitation underground cable quick height adjusting support. The support comprises a supporting platform, a first fixing device, a second fixing device, a supporting vertical plate, a rotary base and a rotary disk. The rotary base is fixedly arranged on the upper surface of the middle of the supporting platform. The rotary disk is rotatably arranged on the upper surface of the rotary base. Two vertical supporting rods are fixedly mounted on the upper surface of the rotary disk. The first fixing device and the second fixing device are arranged on the upper portions of the two supporting rods correspondingly. The supporting vertical plate arranged in the vertical direction is fixedly mounted on the upper surface of the supporting platform. The mineral exploitation underground cable quick height adjusting support is simple in structure, convenient to operate, capable of realizing quick adjustment of the height and angle of cables and saving time and labor and high in practicality.

The invention discloses the application method of the cutter used for cleaning the inner wall of pipe fittings. When the central axis rotates the arc-shaped blade and contacts the solder residue and protrusions on the inner wall of the steel pipe, the interaction force on the arc-shaped blade produces a relatively large impact on itself , the stopper can provide support for the arc-shaped blade when the angle between the arc-shaped blade and the central axis reaches the maximum and also when the arc-shaped large piece is impacted the most, so as to avoid damage to the arc-shaped blade.

The invention discloses a removing mechanism for burrs in straight welded steel pipes. The removing mechanism comprises a support barrel and blade angle adjusting mechanisms. An end of the support barrel is connected with an external core rod, a plurality of rollers are arranged on the support barrel, a driving motor is arranged in the support barrel, an output end of the driving motor is connected with a cutter, the cutter comprises a center shaft, a plurality of arc-shaped blades are arranged on the center shaft, are hinged to the center shaft and are annularly arrayed and distributed on the outer wall of the center shaft, fixing plates are mounted at the upper end and the lower end of the center shaft, the arc-shaped blades are arranged between the two fixing plates, and the blade angle adjusting mechanisms are arranged among the arc-shaped blades. The removing mechanism has the advantages that the blade angle adjusting mechanisms are flexible in connection mode and simple in structure, accordingly, included angles among the arc-shaped blades and the center shaft can be quickly adjusted while the arc-shaped blades are assuredly firmly fixed, the abnormal machining time can be shortened, the efficiency can be improved when welding flux residues and protrusions on the inner walls of the steel pipes are cleaned, and the service performance of the steel pipes can be guaranteed.

The invention relates to a multi-pointer controller for controlling the time and the direction of curve flight. The controller comprises a B shaft gear system which is provided with spiral spring strips to be used as the rotating power, a C shaft gear system and a D shaft gear system which are respectively provided with three transmission gears, a E shaft gear system and an F shaft gear system which are respectively provided with two transmission gears, and a pointer system which is provided with five concentric center shafts sheathed together, wherein one end of each center shaft is provided with a transmission gear, and the other end of each center shaft is provided with a heavy pointer. The controller is characterized in that rotary spiral spring rotating discs of the B shaft gear system enable the spiral spring strips to tightly rotate around B shafts, thereby forming the restoring force of the spiral spring strips, i.e. the power to drive the spiral spring rotating discs; the tighter the spiral spring strips rotate, the bigger the restoring force of the spiral spring strips is; the faster the rotating speed of the spiral spring rotating discs in an anti-clockwise direction is, the less the time for rotating one circle for the spiral spring rotating discs; a timing control rotating disc is limited by a limit rod of the timing control rotating disc to only rotate one circle with 360 degrees.

The invention discloses a tool for removing burrs inside a steel tube. The tool comprises a center shaft, three arc-shaped blades are arranged on the center shaft, hinged to the center shaft, and located on the one-third outer walls of the center shaft respectively, the upper end and the lower end of the center shaft are respectively provided with a fixing plate, the arc-shaped blades are arranged between the two fixing plates, check blocks are arranged on the fixing plates, one side of each check block is an arc-shaped concave surface, the arc-shaped concave surfaces make contact with arc outer side lines of the arc-shaped blades. The tool further comprises blade angle adjusting mechanisms arranged between every two adjacent arc-shaped blades. According to the tool, removing efficiency of welding flux residues and protrusions on the inner wall of the steel tube is improved, when the center shaft rotates and the arc-shaped blades make contact with the welding flux residues and the protrusions on the inner wall of the steel tube, the arc-shaped blades are greatly impacted by interaction force exerted on the arc-shaped blades, the check blocks can support the arc-shaped blades when the included angle between the arc-shaped blades and the center shaft is maximum and the arc-shaped blades are impacted to the maximum degree, and therefore the arc-shaped blades are prevented from damage.
