Such manual wrenches, pneumatic wrenches or electric wrenches include a handle and a work head, and the handle and the tool head can be combined and separated. In order to work in a narrow space, an extension rod is often provided between the handle of the hand wrench and the tool head. But the hand = wrench is not fast enough; the pneumatic wrench or the electric wrench, but no extension rod, it is difficult to work in a narrow space. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a power torque wrench that can operate in a narrow space. The car can be turned by the wheel. - the material is pressed against the second ratchet member and the two-spindle torque adjusting mechanism can be operated to adjust the degree of compression of the spring relative to the first, that is, the one and two ratchet members are sprayed The degree of contraction is the first torque. The private degree, that is, the dynamic torque wrench can be transmitted. The invention relates to a dynamic torsion wrench comprising a handle. - Connect the handle inside. - The lancet spits the helical gear. An extension rod '(4) can be rotated simultaneously. - The shaft is located in the handle. - The person comprises a first ratchet member and a second ratchet member and the two can be connected to the extension rod. The second ratchet member is relatively movable but not relatively rotatable. A barrel connection 200944336 Next, with the diagram, the explanation can be made to familiarize yourself with the technology. The following is a more detailed understanding of the explanation. It is not intended that the preferred embodiment of the invention be construed as limiting the invention. Therefore, 'everything should still belong to the invention's intention to protect = can be form of modification or change, [Embodiment] 坷Ο ❹ hand shell 34 Tuoli TM one shell 4 has - closed end 6, _ ^ = 8, and Combined by screwing. Each closed end 6. Open end 8, - hole 10. The hole 10 is rotatable adjacent to the gear 12 and an oblique. The outer sides of the two sub-angles are brought into close contact so that the = 2 helical gear 14 and the rotor 12 are rotatably placed in the handle 2 so that the sub- 12 is seen from the hole 1 . τμΓΓΓΓΓ力杨扳手 There are also women16. The worm 16 is rotatably placed in the hex 9 1 16 with a hexagon _. 1_#16###胄14, the rod is rotatably placed into the handle 2 by a bearing '. The extension rod 18 has a hexagonal end and a quadrangular end. The hexagonal end of the extension rod 18 is in close contact with the hexagonal inner side of the volute 16 so that the two can be rotated together. The clutch is rotatably placed in the handle 2. The disengager includes a first ratchet member 2G and a second ratchet member. Available - the tubular member covers the first 200944336 ratchet member 20 and the second ratchet member 22. The first ratchet member 20 can engage the second ratchet member 22 to transmit torque. If the torque exceeds a set value, the first ratchet member 20 is disengaged from the second ratchet member 22. The first ratchet member 20 has a quadrangular inner side that is in close contact with the quadrangular end of the extension rod 18 so that they can rotate together. The second ratchet member 22 has a plurality of longitudinal grooves 24 on the inside. A shaft 26 has a rounded end 27 and a hexagonal end 29 and a plurality of longitudinal grooves 28 at the rounded end 27. A plurality of clusters of steel balls 30 are placed into the grooves 28 of the shaft 26 and the grooves 24 of the second ratchet member 22 so that they can be rotated together. More specifically, each of the steel balls 30 has a portion in one of the grooves 28 of the shaft 26 and another portion in a groove 24 of the second ratchet member 22. A ring 32, a spring 34 and a disk 36 are placed over the shaft 26 such that the ring 32 and the disk 36 press against the spring 34. Ring 32 blocks steel ball 30. The disc 36 has a hexagonal inner side that is in close contact with the hexagonal end of the shaft 26 so that the two can be rotated together. The disk 36 has a plurality of recesses 38 at one end. A cylinder 40 has a hexagonal hole 41 and a plurality of recesses 42 at one end and a square hole 43 at the other end. The hexagonal bore 41 of the barrel 40 receives the six-corner end 29 of the shaft 26 so that the barrel 40 and the shaft 26 can be rotated together. The square aperture 43 of the barrel 40 can accommodate a portion of a tool head. A plurality of steel balls 44 are placed in the recess 42 of the cylinder 40 and the recess 38 of the disk 36. More specifically, each of the steel balls 44 has a portion in a recess 42 of the barrel 40 and another portion in a recess 38 of the disk 36. A torque setting mechanism is placed in the handle 2 and connected to the barrel 40. The torque setting mechanism includes a hollow bolt 46, a first nut 48, and a second nut 50. The hollow bolt 46 engages the first nut 48 and the second nut 50. The hollow bolt 46 encloses a section of the barrel 40 and abuts against the other end of the barrel 40. The first nut 200944336 48 is non-rotatably placed in the handle 2. The second nut 50 is placed outside the handle 2. If the power torsion wrench of the present invention is an air wrench, an air compressor is connected to a transmission mechanism during use, and the transmission mechanism is coupled to the air wrench. The air compressor provides high pressure air to rotate the transmission mechanism, and the transmission mechanism rotates the pneumatic wrench. If the power torsion wrench of the present invention is an electric wrench, the motor is connected to a transmission mechanism during use, and the transmission mechanism is connected to the electric wrench. The motor can rotate the transmission mechanism, and the transmission mechanism rotates the electric wrench. Referring to Figure 4, the transmission mechanism rotates the rotor 12. The rotor 12 rotates, and the gear 14 is rotated. The helical gear 14 rotates the worm 16. The worm 16 rotates the extension rod _ k to extend the first ratchet member 2 转动. The first ratchet member 2 turns the two ratchet members 22. The second ratchet member 22 rotates the shaft 26 by means of the steel ball 30. Shaft, moving barrel 4G. The barrel 4G can rotate the head of the guard. The tool head can be rotated by a screw or nut. ® Force a Refer to Figure 5 'When the torque required to turn the bolt or nut is greater than the torque that the dynamic screw can provide, the second ratchet 22 follows the bolt or the self-moving, first ratchet 2〇 Rotate due to the transmission mechanism. In other words, force. The first ratchet member 20 is rotated relative to the second ratchet member 22 and cannot be twisted. Referring to Figure 6, the torque provided by the dynamic torque wrench is adjustable =, . First, the tightness of the second nut 50 and the hollow bolt 46 is released. It is not necessary to completely separate the two. Next, the hollow bolt 46 is rotated and moved relative to the first cap 48. Therefore, the cartridge 40 moves. The spring 34 is pressed ',' to a varying extent. The first ratchet member 20 engages the second ratchet member 22 with a change of degree of 200944336. In other words, the torque provided by the dynamic torque wrench changes. Accordingly, it can be understood that the present invention is an innovative invention, which not only effectively solves the problems faced by the practitioner, but also greatly enhances the efficacy, and does not see the same or similar product invention or public use in the same technical field. At the same time, it has the effect of improving the efficiency. Therefore, the present invention has met the requirements for "novelty" and "progressiveness" of the invention patent, and is filed for patent application according to law. 〇 9 200944336 [Simple description of the drawings] Fig. 1 is a perspective view of the dynamic torsion wrench of the present invention.
