Description of the Invention: [Technical Field of the Invention] The present invention pertains to the technical field of torque measurement, and more particularly to a measuring mechanism suitable for a ratchet wrench. [Prior Art] An existing ratchet wrench, like the U.S. Patent No. 4,87,879, the exposed wrenches are connected through a torque output structure to one end of the pipe and the other end of the pipe. Put and install a torque adjustment device between the handles. ', This torque adjustment device includes a set of adjustments on the handlebar. The adjustment knob displays a number of scales next to the edge of the handlebar. These scales are separated by an appropriate distance and can only measure the metric unit N_m (Newton-meter), imperial units. The approximate value of ib-ft (crush-suction) or the unit system kg_m (kg-meter) cannot measure the exact torque value. Similar torque measurement techniques include US 2,2〇5,5ι〇 m '% 4,248,107 #u . % 7,044,036 % > % 7,631,583 • and D257,626. However, there are still the following shortcomings: First, the torque measurement of these patent cases: by means of the hand to rotate the opposite pipe, to visually measure the edge of the handle to the surface of the tool, which is easy to cause some error in the measured value due to the angle. Second, the aforementioned measurements are accurate to the hundred or ten digits, but the single digits are rather vague. Especially in the US Patent No. 7,631,583, the measured torque value is compared with the electronic measuring instrument to confirm the adjustment result. 201204512 3. In the US Patent No. 7,631,583, it is necessary to dial each disk to adjust the torque value of the wrench. The operation is quite cumbersome and very inconvenient for the user. In view of this, the present inventors have intensively studied the problems of the prior art, and actively sought a solution to the experience of R&D and manufacturing of related industries in the eve of the year, and finally developed a torque measuring mechanism for the wrench to improve the problem of the conventional invention. SUMMARY OF THE INVENTION Therefore, one of the objects of the present invention is to convert a linear displacement into a self-rotating motion, and precisely measure the torque value and transmit it to; a window presents the measurement result to avoid the error of the line of sight angle, thereby helping The user can easily identify the adjusted wrench torque value. For the above purposes, the wrench of the present invention comprises: a wrench, including a head; a handle for holding; a tube member, the tube body is provided with an elongated hole, one of the two ends is coupled with the handle, and the other is The end is connected to the head through a torque output configuration; the one-twist, adjusting device 'includes an adjustment knob assembled on the handlebar; and a latch mounted between the official member and the handlebar, movable in the elongated shape in response to the rotation of the adjustment knob a torque measuring mechanism mounted on the wrench, comprising: a set of measuring cylinders outside the tubular member, having a spiral track trapped in the inner wall of the measuring cylinder, the rail wall surface contacting the plug; a plurality of scales displayed on the outer surface of the measuring cylinder; A woman's fixing ring for the official part, with the handlebar restricting the measuring cylinder to rotate outside the pipe but not to be displaced along the length of the pipe; 201204512 A casing located outside the measuring cylinder, having a window disposed on the sleeve facing the scale . Wherein the torque measuring mechanism further comprises a first ring body, which is sleeved outside the measuring cylinder according to the concave and convex fitting means, and displays the required scale on the surface of the first ring body. In addition, a scale is attached to the outer surface of the first ring to display the desired scale on the surface of the scale. The torque measuring mechanism further comprises a second ring body, which is placed on the position of the adjustment button and penetrates the handlebar according to the concave and convex fit, and displays the required fine adjustment scale on the surface of the second ring body; the handle has a fine adjustment window, Located on the part of the handle that faces the fine adjustment scale. In particular, the second ring surface is attached to a fine-tuning scale to display the desired scale on the surface of the fine-tuning scale. Of course, these scales or fine-tuning scales should be replaced by one of numbers or symbols. The window of the casing is fixed with a transparent cover, and an index is set on the inner surface of the transparent cover; and the fine adjustment window of the handle is fixed to a transparent member. In this way, the latch will linearly reciprocate along the wall of the elongated hole with the rotation of the adjusting knob, and drive the measuring cylinder to rotate outside the official member, and the second ring will also follow the adjusting button. Rotate in the same direction, and the torque value can be instantly known from the two windows. In addition, the transparent cover or transparent member can prevent foreign objects from intruding into the two windows, protecting the scale from the fouling, and the index can avoid the error of the line of sight angle and the accuracy of the weight measurement. With regard to the techniques, means and functions of the present invention, the following examples of the mussels are described in detail with reference to the drawings, and it is believed that the above objects, structures and features of the present invention can be obtained from an in-depth and specific To understanding. 5 201204512 {Embodiment] The following is a detailed description of related embodiments based on the drawings. Referring to Figures 1 to 3, it is disclosed that the wrench 1 is connected to the head 12 at one end of the pipe member u, and the handle member 9 is coupled to the handle 13 at the other end, and the elongated hole 14 is formed in the pipe body. With the head 12 of the wrench 10 acting as a fulcrum, an external force is applied to the handlebar 13, and the swinging pipe member u reciprocates; *, the torque can be transmitted to the workpiece through the head 12. Here, the pipe member 11 is coupled to the head 12 through the torque wheeling structure 2''. The torque output structure 2 includes a magazine 2 placed inside the tube member 11. For the rest of the structure, please refer to the US Patent No. 4, 87, 879, which is not the focus of the case, and therefore will not be described. A torque adjusting device and a torque measuring mechanism 5G are installed between the official member 11 and the handlebar 13, and the torque value is displayed at any time by the torque measuring mechanism %. The torque adjustment device 3 includes at least a button 3 and a pin 32, and the adjustment button 31 is assembled at the end of the handlebar 13, and the torque outputted by the head 12 performs an adjustment operation, and (4) 32 is rotated according to the button 31. It is possible to move in the elongated hole 4 θ. Regarding the connection relationship between the adjusting knob 31 and the latch 32, the following is stated as follows: 1. From the structural point of view, the adjusting button 31 is sleeved on the outer periphery 1434 of an inner button 33, and the second twist has a concave-convex relationship and can be placed together. = + U end α. The inner magical 3-axis portion is locked and pushed, and the screw 35' has no connection with the handle 13, but can guide the outer button 34 to slidably catch the handle 13 and cannot rotate. The pusher screw 35 is placed in the core of the pipe, and one end of the small rod diameter branch 36' passes through the Palin 40 positioned in the pipe member 11, and 201204512 1缟. [5 screwed to the center of the inner button 33; the push screw % is further terminated as an i-thread ^37, which is screwed together with a pusher tube 38 incorporated in the pipe member 11, and is held by the nozzle of the pusher pipe 38. The spring 21 causes the pusher cup 35 to be pressed toward the Palin 40. In addition to the coma of the push tube %, the latch 32 is fixed by the pressing means, and the latch 32 is partially inserted into the elongated hole 14. As for the Palin 40, it consists of a fixed seat 41, a plurality of steel balls 42 and a Huashi 43. The fixing base 41 is a ring body and is positioned in the tubular member by means of a latch. The washer 43 abuts against the wall surface of the middle portion of the screw 35, and the steel seat 42 is sandwiched by the fixing seat 41 to provide a low friction rate to the propeller screw 35. From the point of view of the effect, the outer button 34 is pulled out until the engagement range of the handle 13 is released, and the outer button 34 is rotated, and the inner button 33 is rotated in the same direction as the push screw 35. The pusher screw 35, under the structure of the Palin 4 and the support section 36, drives the propulsion tube 38 to be displaced by the spinning thread section 37. Since the latch 32 is constrained to the wall surface of the elongated hole 14, the pusher tube 38 does not rotate with the threaded section 37, and the spring 21 can only be deformed along the length of the tubular member 11 to adjust the torque. Looking back, 'see the torque measuring mechanism 5〇 of Figures 1 and 4, including the window 51 and the fine-tuning window 56, each window being covered by a transparent cover 52, a transparent member 57 or a lens, protecting the scale 54 or the number 55 from contamination Damage to objects and grease. Wherein, the transparent cover 52 is provided with an index 53 on the surface facing the scale 54 or the number 55. The index 53 is a line in the embodiment, but does not exclude the possibility of the symbol 'such as a triangle opening ^, a circle, a dot, and the like. . These scales 54 or 55 are displaced according to the rotation of the 201204512 adjustment button 31. By the index 53 of the window 51 plus the scale 54 or the number 55 of the fine adjustment window 56, the torque value of the wrench 10 can be easily interpreted, and the single digits are accurately measured. Or the value after the decimal point, in the technical field of mechanical torque measurement, it is apparent that the measurement effect of the prior art is superior. As for the technical content of the torque measuring mechanism 50 moving the scale 54 or the numeral 55, it can be detailed as follows through the second, third, and fifth figures: In the present embodiment, the torque measuring mechanism 5 is composed of the measuring cylinder 6〇 and the fixing ring 70. And the sleeve 80 is composed. ° 罝 罝 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 One. The circumference of the first ring body 63 is adhered to the scale 64, and the scale 5 4 or the number 5 5 is required to be brushed on the scale. The measuring cylinder 6 is sleeved on the outside of the piece 11 so that the first ring body 63 or the scale 64 is located in the window amount 2 and the fixed ring 7 is matched with the handle 13 to limit the measuring door * the official piece / 1 external rotation, but Can not be in the direction of the tube length " one to maintain the contradiction:: face 'still with the local protruding tube in more detail, the test; ^ help measuring tube ^ white end each close to one of the Palin 40, Fixed = from:: Reduce the friction rate. The two priests 43 are sandwiched by _42.23 instead of the fixed seat 41' with the ^1 Lin 4〇 structure installed by the Huajin screw h, which is the same as the above-mentioned push ^ peripheral adjacent Changguan Γ 4=; the Palin 4G is positioned together in the pipe fittings Put in the handlebar 13 inside. The core is assembled with the partial measuring cylinder 60 201204512. The sleeve 80 is sleeved on the fixing ring 7〇, and the two are positioned by a pair of screws 81 at the periphery of the tubular member U adjacent to the elongated hole 14. The sleeve 80 is formed at the other end by a step portion 82, which is placed inside the handle 13 and has a resisting relationship. Further, the tube body forms a ridge portion 83 through which a desired window 51 is inserted in the middle portion of the ridge portion 83. The button 31 is deep into the portion of the handle 13, and the second ring body 84 is sleeved by the concave-convex fitting means. The toroidal surface faces the portion of the fine adjustment window 56, and the desired scale or number is created by the printing means to serve as the fine adjustment scale 85. Of course, these fine adjustment scales 85 can also be printed on the fine adjustment scale and attached to the periphery of the second ring body 84. The torque measuring mechanism 5 of the present embodiment operates in synchronization with the torque adjusting device 30. Wherein, the second ring body 84 rotates synchronously according to the adjusting knob 31, and the rotation speed ratio of the two rings 84 is about 1:1, so the fine adjustment scale 85 of the fine adjustment window % is quickly changed. As for the advancement screw 35, although it is also rotated synchronously with the adjustment knob 31, it is converted into a stroke of the screw pitch by the threaded section 37 in conjunction with the advancement 38; and the bolt 32 pushes the wall of the spiral square rail 61 to drive the measuring cylinder 6 to rotate. The ratio of the inclination of the spiral track 61 to the pitch of the thread segment 37 directly affects the rotational speed of the first ring body 63, causing the speed of the scale 54 of the window 51 to be lower than the fine adjustment scale 85, such as Figures 2, 0, and 7. Briefly, the knob 31 is rotated once, and the second ring body 84 is also rotated once, but the first ring body 63 can only be rotated by about 1 to 3 scales. Therefore, the torque measuring mechanism 5〇 of the present embodiment has the following advantages: 1. In response to the rotation of the adjusting button 31, the latch 32 linearly reciprocates in the elongated hole ' 'with the wall of the touching spiral trajectory 61, and drives the test 201204512 measuring cylinder 60 Rotating outside the tube member 11; in addition, the second ring body 84 is also rotated in the same direction with the adjustment 31, and the torque value can be instantly obtained from the two windows 51, 56. 2. The transparent cover 52 or the transparent member 57 can prevent foreign objects from intruding into the two windows 51 and 56, protect the scale 54 and fine-tune the scale 85 from the fouling, and the index 53 can avoid the error of the line of sight angle and improve the accuracy of the weight measurement. degree. 3. The transparent cover 52 or the transparent member 57 can be replaced by a lens having a magnifying effect to facilitate the user's interpretation of the torque value. The above-described embodiments are merely illustrative of the invention and are not intended to limit the invention. Various changes, modifications, and applications derived from the above-described embodiments are apparent to those skilled in the art.
