INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to the use of the principle of levers to adjust the structure of a sound wheel of a torque wrench by means of a lever, a nut, or a nut The wrench heart is enough to set the pressing force. 'When the pressing force reaches the preset, the wrench sounds. The invention is designed to match the sound wheel that produces the sound. Unique design/production [previous technique] Press, screw and nut in operation Chasing or loosening is mostly done with a force wrench. The use of a wrench is to provide a force 1 by providing a screw or nut at one end and a lever 1 for extending the extension rod at the other end. The size of the force of the turning cannot be known, so it is usually turned to the tightest state according to the force of the turning person, but the workpiece and the machine j are not suitable for the tightening. The force of the screw and the nut must be locked. Within a circle, the 'Taisong structure is easy to loosen and loose, and if it is too tight, it is easy to cause structural damage'. Therefore, there is a wrench that can control and adjust the locking force. Raw, the torque wrench includes: a wrench body, a sleeve, a social pin, a sound wheel and a top abutting element 'where the wrench body, the casing:: the pin and the top member can be referred to the i As shown in the figure, the sound wheel 7 () please refer to the ninth, the pin shows that the wrench body has a tool head and has a tool bar extending along the end, and the tool bar has a matching groove at one end. The sleeve is sleeved on the tool post of the wrench body, and the handle body is combined with the 1337920 sleeve by the joint pin. The sound wheel 70 is received at one end of the sleeve and is combined by the top member. At one end of the sleeve, the acoustic wheel 70 is simultaneously pushed against, and the sound wheel 70 simultaneously contacts the mating groove of the tool bar, and the force generated by the abutting member transmits a limiting force to the tool rod through the sound wheel 70. When the wrench is turned, when the force of the turning is greater than the limiting force of the abutting component, the wrench body will instantaneously generate a displacement, and the tool bar strikes the inner surface of the casing to make a sound, thereby reminding the user that the wrench's turning force The preset has been reached. At present, the structure of the acoustic wheel 70, as shown in FIG. 9, is composed of a wheel housing 71, a roller 72 and a wearing rod 73. The sound wheel housing 71 is completed by punching.

The shell 71 rolls on. The aforementioned acoustic wheel structure uses the following drawbacks: the acoustic wheel housing 71 of the acoustic wheel 70 is of a cover-like design, so that the machining must be completed by stamping, and the stamping of the acoustic wheel housing 71 must limit the thickness of the metal plate. If the use of the metal plate is too thick, it will cause processing difficulties and reduce the yield of the process. However, if the metal plate is too thin, there will be a disadvantage that the sound wheel 70 is inferior in strength and easy to be damaged, and the cover design of the sound wheel 71 has -+, The setting of the cymbal and the wearing rod 73 is also a paste, which is not only disadvantageous to the roller mode.
