A fixed jaw member is provided at the distal end of the torque wrench, and the fixed jaw member is provided with a curved elongated hole to support a movable jaw member having a pin that is loosely fitted into the elongated hole, and further fixes the movable jaw member. A torque wrench with a ratchet has been developed in which a spring means is interposed between the jaw member and the movable jaw member for biasing the movable jaw member in a direction in which the distance between the jaws of both jaw members is narrowed. According to this torque wrench with a ratchet, the distance between the jaws of both jaw members can be changed by changing the position of the pin provided on the movable jaw member along the elongated hole provided on the fixed jaw member. This makes it easy to tighten bolts and nuts of different sizes.
以下に本考案を図面に示す実施例に基いて詳細に説明す
る。The present invention will be explained in detail below based on embodiments shown in the drawings.
１はトルクレンチレバーであって、このレバー１の先端
には支持ピン２を介して固定顎部材３の一端部３ａが枢
支されている。1 is a torque wrench lever, and one end 3a of a fixed jaw member 3 is pivotally supported at the tip of this lever 1 via a support pin 2.
またこの固定顎部材３の他端は顎部３ｂに形成されて訃
り、更に該固定顎部材３の中途には湾曲する長孔４が穿
設されている。The other end of the fixed jaw member 3 is formed into a jaw portion 3b, and a curved elongated hole 4 is bored in the middle of the fixed jaw member 3.
５は略鈎状に形成された可動顎部材で、この可動顎部材
５の一端５ａには上記長孔４内に遊嵌されるピン６が固
定されており、その可動顎部材５の他端には顎部５ｂに
形成されている。Reference numeral 5 denotes a movable jaw member formed approximately in the shape of a hook. A pin 6 that is loosely fitted into the elongated hole 4 is fixed to one end 5a of the movable jaw member 5, and the other end of the movable jaw member 5 is formed in the jaw portion 5b.
７は固定顎部材の側面に形成した有底穴８内に入れ込ま
れているスプリングであって、このスプリング７の先端
には突子９が連結されており、更にとの突子９の先端は
可動顎部材５に形成した段部１０に当接されているもの
で、このスプリングＴの弾圧力で固定顎部材３と可動顎
部材５の顎部３ｂと５ｂとの相互間が狭められる方向に
作用されている。A spring 7 is inserted into a bottomed hole 8 formed on the side surface of the fixed jaw member, and a protrusion 9 is connected to the tip of the spring 7. is in contact with a stepped portion 10 formed on the movable jaw member 5, and the elastic force of this spring T narrows the distance between the fixed jaw member 3 and the jaw portions 3b and 5b of the movable jaw member 5. is being affected.
１１は固定顎部材に固定したストップピンであって、こ
のストップピン１１は可動顎部材５に形成した楕円孔１
２内に位置され、その可動顎部材５がスプリング７の弾
性力で異状に開かないように位置規制するものである。11 is a stop pin fixed to the fixed jaw member, and this stop pin 11 is inserted into the oval hole 1 formed in the movable jaw member 5.
2, and the position of the movable jaw member 5 is restricted by the elastic force of the spring 7 so that it does not open abnormally.
以上が本実施例の構造であるが、次にその作用について
述べると、可動顎部材５はピン６を介して固定顎部材３
に連結されているが、そのピン６は固定顎部材３に設け
た長孔４に遊嵌されているため、そのピン６を長孔４の
一端４ａに位置せしめた時は、双方顎部材３と５の顎部
３ｂと５ｂとの相互間が比較的狭められ、小型のボルト
・ナツトＡをくわえるのに有利である。The structure of this embodiment has been described above. Next, the operation will be described. The movable jaw member 5 is connected to the fixed jaw member 3 via the pin 6.
However, since the pin 6 is loosely fitted into the elongated hole 4 provided in the fixed jaw member 3, when the pin 6 is positioned at one end 4a of the elongated hole 4, both jaw members 3 The spacing between the jaws 3b and 5b of 5 and 5 is relatively narrow, which is advantageous for gripping small bolts and nuts A.
′ｉ！たピン６を長孔４の他端４ｂに位置せしめた時は
双方顎部材３と５の顎部３ｂと５ｂとの相互間が比較的
に広げられるので大型のボルト・ナツトＡ′をくわえる
ことができる（第３図参照）。'i! When the pin 6 is positioned at the other end 4b of the elongated hole 4, the distance between the jaws 3b and 5b of the double-jaw members 3 and 5 is relatively widened, making it easier to hold a large bolt/nut A'. (See Figure 3).
またスプリング７の弾圧力で、双方顎部材３と５がボル
ト・ナツトに弾圧的に挾持される作用があるために、ボ
ルト・ナツトの挾持が迅速かつ容易になされる効果があ
る。Further, since the elastic force of the spring 7 has the effect of elastically clamping the jaw members 3 and 5 to the bolt/nut, the bolt/nut can be clamped quickly and easily.
かくして双方顎部材３と５がボルトナツトに挾持された
後にレバー１を締付方向に回動すればレンチ作用によっ
て双方の顎部材３，５とボルト・ナツトとの挟持力は高
められ、該ボルト・ナツトを確実に締着することができ
るものである。In this way, when the lever 1 is rotated in the tightening direction after the jaw members 3 and 5 are clamped by the bolt/nut, the clamping force between the jaw members 3, 5 and the bolt/nut is increased by the wrench action, and the bolt/nut is clamped. This allows the nut to be securely tightened.
以上述べたように本考案は、略中央部に湾曲した長孔を
