[Prior Art] It is known that a torque wrench is a wrench for protecting a bolt or a nut _ tool. When the reaction force of the wrench turning the bolt or the nut exceeds a preset torque value, the ferrule unit can be formed to escape and idling. In order to prevent the bolts or snails from being bitten, disintegrating or slipping due to the force applied, and preventing the problem of being unable to be removed in the future, the existing torque wrench is mainly as shown in the first and second figures. The utility model is provided with a torque device (2〇) in a hollow shank (1〇) with a ferrule unit (15) at one end, the torsion device (2〇) comprising a push rod (21) connecting the ferrule unit (15) And a compressible compression 15 compression spring (22), and the compression spring (22) is provided on the handle (1〇) with a button (23) for adjusting its force, and in order to maintain • push The rod (21) acts to stabilize and verify the compression spring (22). A toggle structure (24) is usually provided between the rods (21), and the dialing structure (24) is attached to the upper end of the end surface of the push rod (21). There is a rolling ball (25 20 ) and a wheel seat (26) on the compression spring (22). The wheel base (26) is pivotally provided with a roller (28) at the corresponding end surface by the cymbal shaft (27). At the same time, in order to maintain the smoothness of the sliding of the wheel base (26), a synchronous offset is provided on the lower side wall of the wheel base (26). The bead (29) of the circumference of the roller (28) and the inner wall of the shank (10), and in order to maintain the balance of the wheel base (26), the bead (29) is generally disposed at the vertical center of the roller (28) 1300740

One side of the toggle structure is disposed on the end surface of the corresponding compression spring of the push rod adjacent to the upper edge and is provided with a rollable ball which is in contact with the circumference of the roller; 10 The specific representation of the technical means allows the torsion force of the torque wrench of the present invention to exceed the set value of the compression spring, and when the push rod is pressed against the roller to push the compression magazine by the ball, the support of the wheel base corresponding to the push rod can be supported to make the wheel base It can maintain parallel movement and improve the problem of adjustment error caused by uneven force of the compression magazine. It can further extend its life span by 15 and increase its added value, while improving the competitiveness and economic benefits of the product. The present invention will be further described in conjunction with the drawings and the drawings, and the present invention will be described in more detail, but the following description is only for explaining the preferred embodiment of the present invention. The embodiment 20 is not intended to limit the scope of the invention, and any modifications or alterations of the invention are intended to be included in the scope of the invention. [Embodiment] The present invention is a torque wrench structure, as shown in the fifth and sixth figures. The torque wrench is provided with a torsion device in a hollow stem 1300740 (1〇) with a ferrule unit (15) at one end ( 20) The torsion device (20) comprises a push rod (2〇 and a compressible compression magazine (22) connected to the sleeve unit (15), and the compression spring (22) is terminated on the handle (295) There is a knob (23) for adjusting its force, and a pusher 5 (2) is provided with a toggle structure (50) between the compression spring (22). The structure and operation principle described above are The same, and not the features of the present invention, will not be described again; for a preferred embodiment of the characteristic structure of the present invention, please refer to the sixth and seventh figures, the toggle structure (5〇) The end of the compression magazine 1〇(22) is provided with a wheel seat (51), and the wheel base (51) corresponding to the push rod ^21) has an accommodation space (52) formed at one end thereof, and the wheel base (51) is placed in the valley A roller (54) is pivotally disposed in the space (52) by a pivot, and the circumference of the roller (54) can slightly protrude from the aforementioned accommodation space. (52), the bottom side wall of the wheel base (51) is formed with a bead hole (55), the bead 15 (55) is internally provided with a bead body (56), and the circumference of the bead body (56) can be synchronized with the roller (54). The edge and the inner wall of the shank (1 〇) are abutted, and the vertical center line of the bead (56) is located on the side of the vertical center line of the roller (54) relative to the push rod (21) (on the same side as the push rod). The bottom of the wheel base (51) is supported, and the structure (5 〇) is pivoted to the end of the push rod (21) corresponding to the end face of the compression 20 spring (22). A rolling ball (57) is pivoted adjacent to the upper edge. 'The ball (57) is in contact with the circumference of the roller; thereby, when the torque wrench is pulled downward, the roller (57) of the push rod (21) can be pressed against the roller (54) of the compression spring (22) Further compressing the aforementioned compression spring (22) by the wheel base (51), so that the ferrule 25 has a single π (15) trip space, and the group constitutes a force-averaged, and can extend the 1300740 using the wrecking torque wrench structure. As for the practical application of the present invention, as shown in the sixth and eighth figures, when the torque wrench turns the screw or the nut, the reaction force exceeds the compression elastic yellow (22). At the preset value, the push rod (21) will move slightly downwards and backwards 5, at this time by the ball (57) rotating the wheel base (51) roller (54), so that the wheel base (51) further compresses the aforementioned compression spring ( μ), let the ferrule (15) jump off and idling, then when the ball (57) presses the roller (54), the wheel base (51) corresponds to the bottom edge of the ball (57) on the same side to the bead (56) The support allows the wheel base (51) to maintain its parallelism, because when the wheel base (51) presses the compression spring (22), the compression spring (22) can be subjected to an average force without affecting The reaction of the compression spring (22) can effectively maintain the accuracy of the torque adjustment, further prolonging its service life, and improving the competitiveness and economic benefits of the product. In summary, it can be understood that the present invention is an innovative creation 15 which can greatly improve the efficacy, and the same or similar product creation or public use is not seen in the same technical field, and the efficiency is improved. The purpose of this article is to express the requirements for "novelty" and "progressiveness" of the invention patents. It is to file an invention patent application in accordance with the law, and pray for the early grant of the invention patent. 1300740 [Simple description of the diagram] The first picture: the appearance of the torque wrench.
