New description: [New technical field] This creation is related to the torque wrench, and more specifically refers to a digital display torque wrench. [Prior Art] According to the conventional digital position type torque wrench, there is mainly a tool head, a handle, a sensing component and a display panel, and the handle is connected to the tool head at one end and is The handle is for the user to hold the force. The sensing component is attached to the outside of the handle adjacent to the tool head for sensing the torque value fed back by the tool head. The display panel is disposed on the handle. The handle is electrically connected to the sensing component to display the torque value measured by the sensing component for the user to know. However, since the above-mentioned torque wrench is too close to the tool head, the torque value sensed and the torque actually applied by the user to the handle are large, and the sensing is close to the tool head. The rigidity of the grip of the component is too large, and it is easy to have an error value in the measurement. ® [New Content] In view of this, the purpose of this creation is to provide a torque wrench with a digital display that senses the torque value more accurately.

Another opposite side of the sensing component platform M341585 is formed with at least a plane; at least - sensing components, for the sense Measuring the torque applied by the user and rotating the telecommunication signal, the sensing component is fixed on the plane of the sensing component platform; the handle is sleeved on the sensing bar for use by the user; The digital display panel is disposed on the handle and electrically connected to the sensing component, and is converted into a torque value by the telecommunication signal outputted by the component. [Embodiment] In order to enable your review committee to have a better understanding and recognition of the features and characteristics of this creation, the following preferred embodiments are described below with reference to the following figures: Please refer to the first to fifth figures. A preferred embodiment provides a digital display torque wrench (100) including a tool head (1〇), a sensing cup (20), a sensing component (30), and a handle (4). 〇) and a digital display panel (5〇). The tool head (10)' is used to fit the object to be turned. The sensing rod (20) has an extension rod (21) and a sensing element platform (22); the extension rod (21) is a rod body having a predetermined length, one end of which is integrally connected to the tool head ( 10) - the side position, and the extension rod (21) is adjacent to the position of the tool head and is controlled to be provided with a positioning shaft (23), and the sensing element platform (22) is sleeved and fixed at one end thereof The free end of the extension rod (21) is such that the sensing element platform (22) has a length distance from the length of the extension rod (21) from the tool head (1), and a through hole is formed on the sensing element platform (22). Two opposite side through holes (221) (in the present embodiment, the through hole has a double tangent circular shape, similar to a figure of eight), and is located on the sensing element platform (22) and the through hole ( 221) A plane (222) is formed on each of the opposite sides of the vertical. The two sensing elements (30) are respectively a strain gauge, and are capable of generating different torsional deformation amounts by different torque values of the M341585, and then outputting the torque value of the telecommunication signal, the second sense The measuring elements (30) are attached to the respective planes (222) of the sensing rods (20). The handle (4〇) has a sleeve (41), a grip member 02), a battery compartment (43) and a cover (44); the sleeve (41) is worn over the sleeve One end of the measuring rod (2〇) is fixed to the extension rod (21) by the positioning shaft (23), and one end of the holding member (42) is locked to the sleeve (41) for the user. For holding, the battery compartment (43) is disposed inside the holding member (42) for accommodating a battery (not shown), and the sealing device (44) is used for closing the grip. Hold the other end of the piece (42) to prevent the battery from falling out. The digital display panel (5〇) is disposed on the holding member (42) and electrically connected to the sensing component (30) and the battery compartment (43) for the battery compartment (43) The battery in the battery is supplied with power, and receives the telecommunication signal from the sensing component (3〇) to display the telecommunication signal (torque value) on the digital display panel (5〇) for the user to know, of course, The digital display panel (5〇) has other setting functions, such as receiving sound from the sensing element (30) when the torque value is too large.疋The above is the description of each component of the digital display of the torque wrench (100) and its related connection methods. Then, the characteristics of its use are introduced as follows: First, because the sensing component (30) is attached Attached to the plane (222) adjacent to the through hole (221), so when the user puts the tool head (10) on the object to be turned, and holds it on the holding member (42) by the human hand When moving, the through hole (221) is deformed by stress concentration, and the sensing element (30) close to the through hole (221) can directly sense the user directly applied thereto. The torque value makes the measured torque value more accurate. In addition, since the sensing element (30) has a predetermined distance from the tool head (10), the torque value measured by the sensing element can be closer to the torque value applied by the user than the torque generated by the tool head. The value can be used to more accurately display the torque value for the user to know. In particular, although the through hole of the above embodiment adopts a two-tangential circle, that is, a figure-like shape, it can actually be presented in other types of holes, such as a circular hole, a square hole, and a triangle. Holes, diamond holes, etc. In addition, although the sensing element platform and the extension rod are two independent members in the above embodiment, in fact, the two can be integrally formed, and the creative purpose of the creation can still be achieved.
