前記ねじ軸９４の一部が前記第２本体９１の外から凸状に露出され、前記ねじ軸９４に第２螺合部９４１が設けられ、前記第２螺合部９４１と前記第１螺合部９２１とが互いに螺合し、前記第２螺合部９４１が前記第１螺合部９２１箇所に螺進変位され、前記ねじ軸９４の一端に第２頭部９４２が設けられ、
前記第３本体９６は前記第２本体９１と互いに組み付けられ、前記第３本体９６が前記第２本体９１に対して回転変位され、前記第３本体９６と前記ねじ軸９４を互いにスリーブ設置し、前記第３本体９６を回転させて変位すると、前記ねじ軸９４が前記第１螺合部９２１箇所に螺進変位するように連動することにより、前記第２本体９１内のばねの圧縮程度を調整して前記トルクレンチ構造のトルク値を調整するように構成されたものである。 In the conventional torque wrench structure, as shown in FIGS. 16 and 17, the torque wrench 90 includes a second main body 91, a first seat body 92, two connecting members 93, a screw shaft 94, and a third main body.

It is configured to adjust the torque value of the torque wrench structure.

しかし、この従来のトルクレンチ構造の欠点は以下の通りである。
１．使用者が前記第３本体９６を回転させることにより、前記第３本体９６を前記第２本体９１上に旋転変位させる場合に、前記第３本体９６は前記ねじ軸９４の前記第２螺合部９４１が前記第１螺合部９２１箇所に螺進変位するように同時に連動し、前記第２螺合部９４１をその端部箇所まで回動させる時に、前記第２頭部９４２が前記第１座体９２の端部と互いに寄せ当てられることにより両者の間がぶつかって摩損をもたらす。
２．仮に、前記ねじ軸９４を既に前記第２頭部９４２と前記第１座体９２を互いに寄せ当てる箇所まで回転したところ、即ち、前記ねじ軸９４を再び回転させる時に、使用者はトルクを調整する動作が既に極限に至ったことを気づかない時に、操作者が前記第３本体９６を再び持続的に回転させる場合、または一部の人がたとえ既に極限まで回転させた後でも、依然として前記第３本体９６を再び継続的に回転させる場合があり、仮に力が少しても過大に加えられると、前記第３本体９６は前記ねじ軸９４上に力を加えてから、前記ねじ軸９４は前記第１座体９２上に力を加え、前記第１座体９２に力を受けた後に、前記第１座体９２は前記２つの結合部材９３による制動のため、一般的に空間上の制限を受けるに従って、前記結合部材９３の外直径が余り大きくなってはならず、前記結合部材９３はその回転する力度合いを受けられずに断裂してしまうおそれがあり、前記第１座体９２は前記第２収容スリット９１２外から脱出する可能性があり、トルクレンチ構造に損害をもたらすことになる。
以上の観点から解決策が求められてきた。 However, the drawbacks of this conventional torque wrench structure are as follows.
1. 1. When the user rotates and displaces the third main body 96 on the second main body 91 by rotating the third main body 96, the third main body 96 is the second screwed portion of the screw shaft 94. The second head 942 is the first seat when the 941 is simultaneously interlocked so as to be screwed and displaced to the first screwed portion 921 and the second screwed portion 941 is rotated to the end portion thereof. When they are brought close to each other with the end of the body 92, they collide with each other and cause wear.
2. 2. Assuming that the screw shaft 94 has already been rotated to a point where the second head 942 and the first seat 92 are brought into contact with each other, that is, when the screw shaft 94 is rotated again, the user adjusts the torque. If the operator continuously rotates the third body 96 again without noticing that the movement has already reached the limit, or even after some people have already rotated the third body 96 to the limit, the third body still remains. The main body 96 may be continuously rotated again, and if a force is applied even a little excessively, the third main body 96 applies a force on the screw shaft 94, and then the screw shaft 94 is the first. After applying a force on the one seat 92 and receiving the force on the first seat 92, the first seat 92 is generally spatially restricted due to braking by the two coupling members 93. Therefore, the outer diameter of the connecting member 93 should not be too large, and the connecting member 93 may be torn without receiving the degree of rotational force, and the first seat 92 is the first seat. 2 There is a possibility of escaping from the outside of the accommodating slit 912, which causes damage to the torque wrench structure.
From the above viewpoints, solutions have been sought.

従って、本発明が解決しようとする課題は、従来のトルクレンチ構造において、前記第２螺合部をその端部箇所まで回動させる時に、前記第２頭部が前記第１座体の端部と互いに寄せ当てられ、両者の間がぶつかってぶつかり損傷をもたらすことを防止することが可能なトルクレンチ構造を提供することにある。 Therefore, the problem to be solved by the present invention is that in the conventional torque wrench structure, when the second screwed portion is rotated to the end portion thereof, the second head portion is the end portion of the first seat body. It is intended to provide a torque wrench structure that can be brought close to each other and prevented from colliding with each other and causing damage.

そこで、本発明者は、本発明の前記課題を解決するため鋭意検討を重ねたところ、前記トルクレンチ構造中に緩衝効果を提供するための第１ワッシャが設けられることにより、前記調整部材の第１頭部を前記固定座と直接ぶつかり合わせてぶつかり損傷を生じることを防止できる点に着目し、かかる知見に基づいて、本発明に想到するに至った。

1. 1. At least one first washer 50 is provided in the torque wrench structure, the first washer 50 is housed in the ring slit 45, and the second thread portion 41 of the adjusting member 40 is the fixed seat 20. When the first head 42 and the fixed seat 20 are rotationally displaced in the first screw thread portion 21 to a position where the fixed seat 20 is attracted to each other, the first washer 50 can provide a cushioning effect, so that the first head 42 can be moved to the first head 42. It collides directly with the fixed washer 20 and does not cause any damage, as shown in FIG.
2. 2. The first washer 50 can provide a cushioning effect when the torque is adjusted to the limit, i.e., when the first head 42 is already in close proximity to the fixed seat 20, even if the adjusting member 40 is rotated again. The first washer 50 can prevent the rotational force of the first head 42 from directly applying a force on the fixed seat 20, and also causes the fixing member 30 to receive a force and rupture. It can be avoided, and the first washer 50 does not directly collide the first head 42 with the fixed seat 20.
3. 3. As shown in FIGS. 3, 13 and 15, the first washer 50 is made of an elastic soft material, and the cross-sectional shape of the first washer 50 is circular, square, X-shaped or various shapes. There may be.
4. The tight structure between the first washer 50 and the ring slit 45 makes it difficult for the first washer 50 to escape from the outside of the ring slit 45 of the adjusting member 40, and the ring slit 45 and the ring slit 45 are described. It is most preferable to have a smaller outer diameter between the second thread portion 41 and the valley bottom, and it is possible to further prevent the first washer 50 from escaping from the outside of the ring slit 45 of the adjusting member 40. can.
5. The grip 60 is assembled with the first main body 10 and is rotated with respect to the first main body 10, so that the grip 60 can be displaced back and forth within the range of the lock slit 14. When the sleeve fitting end 46 is sleeve-installed at the end portion of the grip 60 and the grip 60 is rotated to displace it, the second thread portion of the adjusting member 40 is provided via the grip 60. By simultaneously interlocking the 41 so as to be rotationally displaced in the first thread portion 21, the degree of compression of the torsion spring 17 in the first main body 10 is adjusted to adjust the torque value of the torque wrench structure. ..
6. As shown in FIG. 15, a second washer 70 is provided, the second washer 70 is placed in the ring slit 45 of the adjusting member 40, and the outer diameter of the second washer 70 is the said of the first main body 10. The second washer 70 can increase the support structure between the adjusting member 40 and the first accommodating slit 12, and in particular, said. The greater the distance the first head 42 of the adjusting member 40 from the fixed washer 20, that is, the larger the torque value of the torque wrench structure, the greater the elastic repulsive force in the torsion spring 17. The more it acts on the first head 42, the more important the support structure of the second washer 70 becomes.
7. It is most preferable to have a rotational effect between the second washer 70 and the ring slit 45, and the frictional wear between the second washer 70 and the ring slit 45 is further reduced so that the second washer 70 has a smaller frictional wear. It is most preferable to have a rotational effect between the first accommodating slit 12 and the first accommodating slit 12, and the frictional wear is further reduced between the second washer 70 and the first accommodating slit 12.
