The entire contents of the case are incorporated herein by reference. FIELD OF THE INVENTION The present invention relates generally to a clamping tool for clamping clamps which can connect various sections of pipes together, and more particularly, to a clamping device for clamping such pipe joints. . Prior art compression fittings are usually a g-shaped sleeve f made of plastic or metal and containing a seal. In order to form a joint between the ends of two pipes, the pipe joints need to be slipped over the ends of the pipes, and then the pipe joints are compressed radially to make a leak-proof joint between the two ends. The joints have considerable mechanical strength and are self-supporting. The pipe joint can be pressed to the end of the pipe using a jaw clamp (such as the < orange clamp tool known in the art). A typical jaw tool includes up to > two arms or jaws. A driving mechanism, such as a hydraulic piston actuated by hydraulic pressure from a pump in the tool, can be used to move the arms. In certain embodiments, at least a portion of the arms may be moved inwardly 'during the clamping operation to directly clamp the pipe joint. In other embodiments, the arm of the rotary driving device can actuate a clamp ring of a clamp pipe joint. ^ ^ The hanging ring consists of two or more clamp ring segments connected together.

Some existing clamp bands can be used for diameters as small as ^ '(P1 2 inches) < diameter, such as the multi-segment clamp bands manufactured by Novopress for use in pipe joint systems. Unfortunately, the tongs tool can not always ideally or nearly ideally clamp the tube. 'This is especially true when the pipe joint has a larger diameter (for example, greater than 2.5 inches). In other words, 'the typical rotary driving device and the jaw ring assembly according to the prior art may not be able to apply the jaw force to the pipe joint uniformly within the piston displacement range. In addition, when used for compression fittings of different sizes, and especially for larger straight pipe joints, the force and displacement distribution of the prior art clamp line is not restrained. Other problems with existing clamp rings include the weight of existing clamp rings, the cost of using existing clamp rings with multiple clamp rings to accommodate different size pipe joints. Some rungs of the prior art are intended to facilitate the rounding of the jaw ring-tube joint closure. For example, U.S. Patent No. 5,598,732 discloses a compression clamp ring that includes a traction band located outside the jaw of a clamp ring. A clamp-light and economical clamp ring. In another-Real Money, No. 6, Wu Guo patent disclosed-compression clamp ring, the compression clamp ring includes a leaf spring located outside the chain of the clamp ring to facilitate the ring Connector. In a re-example, U.S. Patent No. 6,058,755 has also disclosed a compression type clamp ring including a plurality of pressure elements that are connected together in a frame manner or in a chain manner by a splint. The present invention aims to overcome or at least reduce the effects of the above-mentioned problems.

The jaw assembly 200 has an inner surface 202 and an outer surface 204. The inner surface 202 may define an internal dimension for the jaw fitting 12. The clamp assembly 200 includes two sector segments 210a and 210b connected by a connector or pin 230; however, it should be understood that the clamp assembly 2000 may have more than two sector segments. As best shown in the cross-sectional view of FIG. 2A, the sector segments 20a and 21b are connected together by a pivot pin 230 fixed by a stop plate 232. Each of the segments 210a and 210b includes an inner surface 212, and the inner surface 212 may include a flange 214. In FIG. 1, the jaw device 10 also includes a flexible member 150 coupled to the actuating assembly 100 and the jaw assembly 200.

In this alternative embodiment, the flexible member 150 may be, for example, a chain, a plurality of coupling elements, or a metal band, which directly surrounds the pipe joint 12 and defines a pipe joint 12 for clamping. Inner surface. The female-actuating element 1110 & and 11 ^) both receive the ring-shaped end portions 156 & and 156b of the flexible member 150 at the bifurcated ends. The split ends 1183 and 11813 of the actuator elements 11a and 110b move relative to each other. When the bifurcated ends 118a and 118b move closer to each other, a dimension defined by the flexible member 15 will change, thereby closing the jaw assembly 200 around the pipe joint 12. The bifurcated ends 118a and 118b may further define a surface for directly contacting and pinching the pipe joint 12 in a centerline gap formed between the fan-shaped segments 21 & 210b of the jaw assembly 200. The flexible member 150 is coupled to the first actuator element 丨 〇a and is coupled to the second actuator element iiOB. The first annular end portion 156a is positioned in the bifurcated end 118 & and the stopper pin 140a passes therethrough. The first annular end portion 15 is rotatable around the stopper pin 140a and the stopper pin 140a. At least one of the ring ends ι56 & and 156b is detachably coupled to a split end 118 & and n8b. For example, the second annular end portion 1561) may be positioned in the bifurcated end, and the second stopper pin 140b may pass therethrough as described below. It should be noted that a stop pin 140a or 140b attached to one of the actuator elements 11aa411〇b in a rigid manner would prevent the replacement of the flexible member 150 and the pliers used with the rotary drive device 100.

Unlike the continuous seamless belt described above in FIGS. 1 and 2A-B, the ends of the integral strip 151 are joined at 161. For example, as illustrated in Fig. 3b ', by stitching the ends of the integral strip 151 made of fibers (such as KEVlar) together, the end connection at 161 can be achieved. However, end joining can be achieved by several methods known in the art for joining the ends of materials, including but not limited to gluing or riveting. Unlike the continuous belt described above, the flexible member 150 may be a unitary belt having a mechanism or structure for forming a ring-shaped end portion 51. For example, as illustrated in FIG. 4a, a fastener or pressure plate 162 may clamp one end of the strap 51 to form an annular end 158, thereby receiving a stop pin (not shown). Alternatively, as illustrated in FIG. 4B, a ring, ring, or other similar structure 166 may be attached to the end of the integral strip 15 by a fastener or pressure plate 164. The ring 66 can accommodate a stop pin (not shown) to connect the flexible member 150 to a rotary drive arm (not shown). To place the jaw device 10 on the pipe joint 12 in FIG. 1, the jaw assembly 200 needs to be opened so that only the first annular end portion 156a of the flexible member 150 is coupled to the actuation assembly 100. The jaw assembly 200 is wound around the pipe joint 12. Thereafter, the second annular end portion 156b is placed in the forked end of the second actuator element ii0b. As best shown in FIG. 2B, the second or detachable stop pin 14ob is inserted into the stop hole 116b defined in the forked end 118b of the second rotary drive arm 110b. The detachable stopper pin 140b passes through the second annular end portion 156b of the flexible member 150. Therefore, the second annular end portion 156b is detachably coupled to the second actuator element 110b and is movable therewith. As mentioned above, one or both of the stop pins 140a or 140b can be removed from the holes 116a or 116b of the actuator 86146.DOC -12-200400091 element 110a or 110b to allow one of the rings to be released from the end 156a or 156b. coupling. Preferably, both of the stop pins 14 and 14 叽 allow the ring ends 156a and 156b to be decoupled from the ends 118 & and 11813, so that the rotary driving device 100 can be used with jaw assemblies of different sizes. Alternatively, one or both of the 'stop pins 140a or 140b may be contracted. For example, as best shown in Fig. 2B, the stop pins 14o & 1413 may define an axial groove 142. The locking element 170 shown in Fig. 1 can be inserted into the split ends 118 & A locking element 170 disposed in the axial groove 142 allows the pins 140a and 140b to move partially axially in the holes 116a and 116b to remove the pins from the annular ends 156a and 156b of the flexible member 150. The locking elements 170a and 170b can further prevent the pins 14 (^ and 14〇b from rotating in the stopper holes 116 and 116b. However, it is not absolutely necessary to prevent the pins 14 (^ and 14〇1) from rotating. Therefore, another A structure, such as an annular shoulder (not shown) on the pin 14 (^ or 14 0b), can be used with the locking element 17 0, so that the pins are not only retractable but also allow them to rotate. See FIG. 5 Other details of the jaw device 10 will be further explained below. An engaging element 190 is positioned between the rotary driving arm 11 (^ and 1103). The engaging element 190 is a jaw for operating the jaw device 10 Part of a tool (not shown). The mocking element 190 is, for example, a roller bearing including first and second rollers 192a and 192b. The roller bearing 19 is moved by a rotary drive device. The rotary driving device may be, for example, a hydraulic piston (not shown) of a clamping tool. The rollers 192a and 192b engage the cam surfaces 112a and 112b of the rotary driving arms 110a and ii〇b. The roller 192a And 192b apply force to the cam surfaces 86146.DOC -13-200400091 112a and 112b to rotate The booms 110a and i10b rotate around the pivot pins 13 (^ and 130b. When the stop pins 140a and 140b with the flexible member 15o ring ends 156 & and 156b are brought together, a clamping force is generated. For example, If the rotary driving device applies a 32 kilonewton output force to the roller support 190, each roller 192a and 192b will receive a force of 16 kilonewtons. When this 16 kilonewton force is applied to the cam surface At 112 & and 112b, the force N generated on the actuator elements 110a and 110b may be about 92 kilonewtons. This force N is initially applied to a pivot 13 of the actuator element 11 (^ and 11〇b). (^ Is away from 13 Ob by A. At this time, a moment will be generated on the actuator elements 丨 丨 (^ and 丨 丨 b), and these actuator elements 11 (^ and 11〇13 will surround the pivot pin 13 (^ And 13 °] 3. When the stop pins 140a and 140b are moved away from the pivot pins 130a and 130b by B, a clamping force Pi will be generated. This clamping force is applied to the flexible member 15. It should be understood The numerical value given in this article is only an exemplary numerical value, and it depends on several design factors such as size, geometric arrangement, tolerance, etc. The force P2 of the flexible member 150 is indicated. The ground is distributed around the outer surface 204 of the jaw assembly 200. The flexible member 150 will exert a force! ≫ 2 is evenly applied to a large part of the outer surface 204 of the jaw ring 200 surrounding the pipe joint 12. If It is assumed that the force p2 is the yield strength of a pipe joint made of tin bronze. For example, the approximate value of the force p is 1 $ 0 Newton / square millimeter: or about 21,755 releases per square inch. For a 25 inch diameter pipe joint 12, the initial radius of the flexible member 15 may be approximately ^ .604 inches; for a 3 inch diameter pipe joint, the initial radius of the flexible member 15 may be Approximately 1.880 inches; for a 4-inch diameter pipe joint, the initial radius of the flexible member 150 may be approximately 2.382 inches. For a 4-inch diameter pipe joint, the annular end of the flexible member 15o 86146.DOC -14- 200400091 The force Pi at 156a and 156b can be calculated to be approximately 25,909 lbs / inch. Therefore, a flexible band 150 made from KEVLAR for clamping 2.5 to 4 inch pipe joints must withstand a force of at least 26,000 pounds without damage. The general width W! Of such a flexible member 150 is preferably 1.75 inches or more. The above values are merely exemplary values, and the values given are used to clarify certain exemplary dimensions and exemplary forces of a specific embodiment of the jaw device 10. Those skilled in the art can use the present invention to select and design other possible specific embodiments with different structural, geometric, or material constraints. Referring to Fig. 6A, this figure shows the jaw device shown in Fig. 5 and other details and elements of the present invention in a cross-sectional view. As described above, the stopper pin 140 can define a slot 142. The split end 118b may define a hole 172 for receiving a locking element 170b. As shown in FIG. 5, the first stopper pin 14a and the split end 118a may also include a similar locking element 17a. Preferably, the locking element pOa-b is a spring-loaded locking element. As shown in FIG. 6A, one end of the spring-loaded locking element 170b is located in the slot 42. When the locking element 17b is spring-loaded, the pin 140b may be inserted into the furcation end 118 and subsequently engaged by the locking element 17. The spring-loaded locking element 170b prevents the detachable stop pin 14b from rotating in the stop hole 116b. In addition, the frictional force exerted on the pin 14 by the spring-loaded locking element nob can fix the pin 14b in the split end in the axial direction, thereby keeping the pin 140b in the clamping process. A closed position. Alternatively, as shown in Fig. 6B, a hole 172 in the split end 172 can receive a spring-loaded ball lock pin 171. The actuating element 11 ob includes a stop lock device 180 adjacent to the detachable pin 4 cents. For example, the stop lock device 18 includes a bearing and

The stop pin 140b may define a slot or slot 144 for receiving a bearing of the stop lock device 180. The locking device ⑽ fixes the locking device on the foot position § Allows the pin 140b to move out of the locking hole 116b when the locking device 180 is offset. If the spring-loaded ball lock pin 171 shown in Fig. 6B is used in the right hole 172, the stop lock device 18 () can be eliminated. As shown in FIG. 5, the width 1 of the opening defined in the bifurcated end of the actuator element 11 is, for example, about 2.125 inches. The width W2 of the flexible member 150 is, for example, about 2 inches. As described above, the maximum bending stress at the price of the stop pin 14 can be calculated using an exemplary force of approximately 25,909 pounds acting on the flexible member 150. For example, if the diameter 0 of the pin 14b is i inches, the maximum bending stress on the pin 140b is about 140,000 pounds per square inch. If the pin 140b has a diameter of ι · 25 inches, the maximum bending stress is about 71,782 pounds per square inch. The above calculations are only exemplary calculations, and the calculations given are used to clarify certain exemplary dimensions and exemplary forces of a specific embodiment of the jaw device 10. Those skilled in the art can use the present invention to design and analyze other possible specific embodiments with different constraints. Referring to FIGS. 7, 8A-B, and 9, these figures illustrate another specific embodiment of the clamp device 20 of the present invention. In Fig. 7, a top view of an actuator assembly 100, a flexible member 150, and a jaw assembly 200 are explained. In FIG. 8A, a cross-sectional view of a flexible member 15o surrounding one of the sector segments 21a of the jaw assembly 200 is illustrated. In Fig. 8B, a sectional view of a stopper pin 14a and an annular end portion 156b of the flexible member 150 are explained. In Fig. 9, a bifurcated end 118a of an actuator element 110a of the actuator assembly 100 is explained in a perspective view. Referring to FIG. 7, the flexible member 150 surrounds one of the outer surfaces of the jaw assembly 200 204 86146.DOC -16- 200400091. In this specific embodiment, the jaw assembly 200 has three coupling segments 210a- c. In this specific embodiment, each sector 21oa_c is connected together by pivot pins ^ ⑹ and 23 Ob. The pivot pins 230a and 23 Ob may further include a twist pin (not shown) to bias the jaw assembly 200 to a shown closed position. Alternatively, the segments 210a-c may be connected by other structures known in the art that do not use pivot pins. For example, each sector 21 oa_c can be connected together by a slotted joint. In this embodiment, the flexible member 150 is a continuous belt including an inner belt 152 and an outer belt 154 that are continuously connected to form the first and second end portions 156 & and 156b. As best shown in Fig. 7, the coupling 丨 60 & and 16 ribs (such as the coupling described above) secure the flexible member 150 to the clamp assembly 200, but provide sufficient clearance to Relative circular motion is allowed between the flexible member 15 and the sector segments 2103 and 21 Ob. In addition, these couplings 6O & and 6S can be used to maintain the size and shape of the middle ring of the ends 156a and 156b. A fixing pin 164 passes through the flexible member 150 to fix the member to the jaw assembly 2000. As shown in cross-sectional view A in FIG. 8A; as best shown, the fan-shaped segment of the jaw assembly 2000 (such as the fan-shaped segment 210a shown) includes an inner surface 212 with a flange 214 and bounds a groove 2 1 5 Each of the looped ends 15 and 15 of the band 150 includes a stop pin 140a and 140b to accommodate the strips 15 2 and 5 4 of the flexible member 15. The stop pins 14 (14 and 14) are detachably coupled to the actuator elements 110a and 110b.

The rollers 3 10 have a larger diameter and extend beyond the height of the links 320a-b and 330a-b. In this way, the roller 310 can constitute a flange. For example, the width of the roller 3 10 may be about 0.188 inches. Roller 86146 DOC -20-200400091 310 The inner links 32 (^ and 32) on both sides can be approximately 0344 inches wide. The outer links 330a-b may have a width similar to the inner links 32〇a_b The overall width of π rollers 3 10 with links 320a-b and 330a-b may be about 15 inches. Referring back to FIG. 12, the actuating assembly 100 includes a first rotary driving arm u〇a and a second Rotary drive arm U〇b. Rotary drive arm 丨 丨 and 丨 丨 仳 are coupled to the first and second end rollers 35 (^ and 35 叽) of the jaw chain 300. The first end roller 350a is set on the table Removably coupled to the stop pin 340a of the first rotary drive device 110a. The first rotary drive device u0a includes a fishing 114 located on the stop pin 340a, so that the first end roller Removably coupled to the first rotary driving device 11a. The second end roller 350b of the jaw chain 300 is located on a fixed stop pin 340b fixedly connected to the second rotary driving arm u〇b. The radius of the partial rollers 35 (^ and 35〇1) can be larger than the other rollers 3 1 0 in the jaw chain 300. The standard pipe joint is a thin-wall pipe joint. In use-traditional pliers During the operation of the ring, a crease or wrinkle will be formed between the closed segments of the clamp ring and especially between the free ends of the clamp cymbals. By including a sufficient number of chains, the pliers of the present invention The clamp chain 300 can achieve substantially uniform compression of the joint. In addition, since the clamp chain 300 exerts a force substantially perpendicular to the surface of the joint 12, the clamp chain 300 of the present invention can reduce or nearly eliminate wrinkles or folds in the joint. Preferably, the jaw chain 300 can be effectively used for pipe joints of many sizes. To achieve this purpose, the 'jaw chain 300 may have a predetermined pitch. The actuation assembly ι 00 is actuated when fully actuated. There is a centerline gap g between the ends of the actuator elements 34a and 34b, so the clamp chain 300 includes one end gap clamp 86146.DOC -21-200400091 The pitch of the chain 300 can be changed to The end gaps G on the size pipe joints are almost equal, so that a single clamp chain 300 can be effectively used for pipe joints of many sizes by simply connecting to a different pin position on the chain. Interconnect members or links 320 and 330 are identified. An inner link 320 is shown in a side view shown in Fig. 13C. The inner link 32 has an edge 322 defined by a radius ruler. The inner link 32 also has adjacent rollers for clamping the chain The distance between the first and second holes 324 and 326 of the sub-pin (not shown) determines the pitch of the jaw chain. This pitch can be selected so that a single chain can be designed for multiple sizes Pipe joints. This pitch is selected as a compromise among several variables, which mainly include the circumference of various pipe joints to be applied, the centerline clearance of the rotary drive arm, the tool stroke, and other edge amounts. The above-mentioned outer link has a side structure substantially similar to the inner link 32o. C. Clamping device actuated by a rotary drive device Refer to Figures 14-16. In these figures, the same reference numerals indicate the same components. 'These figures illustrate the specific implementation of the clamp device used with a rotary drive device 450. example. The rotary driving device 450 may be, for example, a conventional electric drill with an electric motor, but it should be understood that other rotary tools may be used that can provide rotation to drive a screw. For example, the rotary driving device 450 may be a manual drill, a pneumatic drill, a sleeve, a ratchet, a wrench, or a screwdriver. Referring to FIG. 14, the jaw device 400 is actuated by a rotary driving device or a drilling machine 45. The orange clamp device 400 includes a jaw assembly 410 having a first sector segment 412a and a second sector segment 41213. The first and second sector segments 412 & and 41 holes are connected by a 86146.DOC -22- 200400091 pivot pin 414, and the jaw assembly 410 can define an inner surface 415 to clamp a pipe joint (not shown) . The first sector segment 412a has a first pivot member or trunnion 420a at its end 416a. The second sector segment 412b has a hook 41 8 on its end portion 41 6b. The second pivot member or trunnion 42Ob is rotatably and slidably placed in the fishing 418, and the hook 418 can be opened to receive or remove the trunnion 420b. A drive member or screw 430 is rotatably connected to the first trunnion 42a & through the second trunnion 420b. The driving screw 430 is connected to a transmission mechanism or a gear mechanism 440. A rotary driving device 450 is coupled to the transmission mechanism or gear mechanism 44 to rotate the driving screw 430 and open or close the sector segments 412a and 412b around the pipe joint. The transmission mechanism or gear mechanism 440 allows the rotary driving device 45 to be coupled by one or more ways, as illustrated by the driving devices 450 and 450 in FIG. It may be useful when space is limited. If the clamp device 400 needs to be wrapped around the pipe joint, the driving screw 430 should be pivotally connected to the first trunnion 420a, and the second trunnion 420b should be removed from the hook 418. Thereafter, the first and second sector segments 412a and 412b are rotated and separated, and the clamp assembly 410 is positioned so that the pipe joint is located between the sector segments 412a and 412b. Then, the driving screw 430 is pivoted to the first trunnion 420a again, and the second trunnion 420b is positioned in the hook 418. In a specific embodiment, the transmission mechanism or gear mechanism 440 includes a universal joint (not shown) or a simple set of gears with a transmission ratio of 1: 丨. In another specific embodiment, the 'transmission mechanism or gear mechanism 440 includes a gear having a transmission ratio that increases the output torque of the rotary drive device 450 to the output torque of the drive screw 430. In addition, the transmission ratio of the mechanism 440 can also reduce the rotational driving device 450 86146.DOC -23- 200400091 to output the RpM of the driving screw 430 to better control the cooling device 400. The transmission mechanism or gear mechanism 440 includes a shaft 452 detachably connected to the chuck 454 of the rotary driving device 450. When the driving screw 43o is actuated by the transmission mechanism or the gear mechanism 440, the second trunnion instrument moves along the rotary driving screw 43o that rotates on the fixed first trunnion 420a. When the sector segments 412a and 412b rotate around the pivot point 414, the hook 418 can accommodate its circular motion. The transmission mechanism or gear mechanism 440 can also include a torque clutch for disengaging to the drive when a predetermined torque value is reached. The rotation of the screw 43 is transmitted. The torque clutch prevents the jaw device 400 from passing through the jaw fitting. It should be noted that the clamp device 400 may have a mechanical limiter, so that when the mechanical limiter acts, the torque on the rotation driving device 450 will suddenly increase. Therefore, under this condition, the torque clutch can prevent the rotary drive device 45, the rig motor or other mechanical components from being damaged or overstressed. In addition, the torque clutch can be adjusted so that the transmission " is connected to the second part of the rotary drive 450 according to the type of pipe joint to be clamped on the pipe. The first and second parts can be engaged with each other, so that the first and second parts will be adjustable: a force ^ is transmitted between them, and when the resistance point is exceeded, the first and second parts Part will come off. Full-Select the torque level. For example, torque clutch = use Zhou Yu: Regarding the control of Yan-PEX system, a 2.5-inch pipe joint is placed on the M-type copper pipe, and a 3-inch pipe joint is clamped on the κ-type steel. The pipes are fine. The torque clutch may include the first part coupled to the driving screw 43 ° and those skilled in the art should understand that the design of the clamping device 400 depends on a number of 86146.DOC -24- 200400091 parameters and variables, such as The size of the pipe joint to be used, the torque and speed of the rotary drive device 450, the pitch and thread of the drive screw 430, the friction of the gear mechanism 440, and other parameters and variables. It should be understood that those skilled in the art will be able to select and calculate appropriate values for these parameters and variables to design a particular embodiment of the jaw device 400. In FIG. 15, another specific embodiment of the jaw assembly 402 includes components substantially the same as the assembly 400 shown in FIG. The difference is that the jaw assembly 402 includes an attachment portion 460 for attaching the jaw device 410 to the driving device 450, so that a smaller tool that is easier to handle can be achieved. The jaw device 410 is attached to the top of the driving device 450 (as shown) or may be attached to the side of the driving device 450. The second trunnion 420 b is positioned in a bifurcation groove 419 instead of a hook, and the transmission mechanism 440 has an opposite shaft 452 for coupling the rotary driving device 450. Therefore, a groove, a cavity, a son, a groove, or a bifurcated end may be used instead of fishing. Referring to Fig. 16, this figure illustrates another specific embodiment of the jaw device 470 which is operated by a rotary driving device 450. The jaw device 470 includes a jaw assembly 472, a transmission mechanism or gear mechanism 480, and driving members or screws 485a and 485b. The jaw assembly 472 includes first and second sector segments 474a and 474b, and defines an inner surface 475 to clamp a pipe joint (not shown) therebetween. The segments 474a and 474b are symmetrically arranged in the assembly 472 and connected to each other by driving screws 485a and 485b. The driving screws 485a and 485b are connected to the first sector 474a and pass through holes in the second sector 474b. The transmission mechanism or gear mechanism 480 includes a drive gear 482 which is rotatably attached to the second sector 474b and has a 86146.DOC -25- 200400091 for attachment to the rotation drive 450 Spur gear for shaft 483. The drive gear 482 has gear teeth that mesh with the gear teeth of the first and second spur gears 484a and 484b, which are rotatably attached to the second sector 474b. Each of the first and second spur gears 484a and 484b includes a threaded hole, and one of the driving screws 485a and 485b is screwed into and passed through the threaded hole. The rotation driving device 450 rotates the driving gear 482 to cause the first and second spur gears 484a and 484b to rotate. Therefore, the threaded driving screws 485a and 485b will move in the threaded holes in the spur gears 484a and 484b, and open or close the first sector 474a relative to the second sector 474b. D.

The jaw assembly 500 can be touched by a rotary drive device from many directions. The pinching ring sector 60a and 60b are connected at a pivot point 66, and each sector 60a and 60b defines a pivot port 62a and 62b. The jaw assembly 500 includes a driving member or screw 510, a driving coupling 520, a first coupling member or arm 530a, and a second coupling member or arm 530b. The first coupling arm 530a includes a port end 532a in the pivot port 62a of the first sector 60a. The port end 532a is preferably shaped to prevent adhesion. The second coupling arm 530b includes a port end 532b in the pivot port 62b of the second sector 60b. The driving screw 510 is connected to the first and second coupling arms 530a and 5 30b. The drive coupling 520 is connected to one end of the drive screw 510. In this specific embodiment, the drive coupling 520 is a universal joint, 86146.DOC -26- 200400091, so that the catch drive device can touch the jaw assembly 500 from many angles, sides and ways. A rotary driving device (which may be a drilling rig) is coupled to the universal joint 520, and the rotary motion is transmitted from the rotary driving device to the driving screw 5 10 by the universal joint 52. Under the action of the driving screw 51G, the first and / or the second arm 53a and 530b can move along the rotating driving screw 51o to open or close the clamp ring sector 60a and 60b. As shown in the figure, the driving screw 51o is rotatably attached to the first coupling arm 53〇a at 53 乜, and the driving screw 51o is screwed into and passes through the -thread in the "-no" g 53 0b Hole 534b.
