The specific embodiment
Below be the utility model preferred embodiment, but therefore do not limit protection domain of the present utility model.
With reference to Fig. 1, Fig. 2, Fig. 5, shown in Figure 6, monkey wrench, mainly comprise movable jaw 1 and fixing trigger piece spanner, fixedly the trigger piece spanner is made up of the fixedly spanner 2 of upper end and the fixedly trigger piece 3 of lower end, described movable jaw 1 and fixedly be provided with adjusting device between the spanner 2, the screw plate of described movable jaw 1 is made up of first screw plate 11 and second screw plate 12, and fixedly the screw plate of spanner 2 is made up of the 3rd screw plate 21 and the 4th screw plate 22; First screw plate 11 and second screw plate 12 are 106 °～110 ° angles, and the 3rd screw plate 21 and the 4th screw plate 22 are 106 °～110 ° angles. and second screw plate 11 and the 4th screw plate 22 are 106 °～110 ° angles.As preferably, choose first screw plate 11 and second screw plate 12 is 108 ° of angles, the 3rd screw plate 21 and the 4th screw plate 22 are 108 ° of angles, and second screw plate 12 and the 4th screw plate 22 are 108 ° of angles; The length of second screw plate 12 equals the length of the 4th screw plate 22.
Wherein first screw plate 11, second screw plate 12, the 3rd screw plate 21 and the 4th screw plate 22 identical length etc.Make the utility model movable jaw 1 and fixedly can form on one side untight regular pentagon between the spanner 2 and pull mouth.State as shown in Figure 1.
Described adjusting device is meant: fixedly spanner 2 is provided with locating shaft 13, activity is with outer tooth nut 32 on the locating shaft 13, and movable jaw 1 is provided with and screws mutually with outer tooth nut 32 outer pitch threads and tooth nut 32 rotations outside drive and drive half screw rod 13 that movable jaw 1 moves as straight line down.The rotation of the outer tooth nut 32 of the utility model drives the translation of half screw rod 13, moves with respect to fixing spanner 2 straight lines thereby drive movable jaw 1.The adjusting device here is the same with the adjusting device in the prior art monkey wrench, is not giving unnecessary details.
Regulate movable jaw 1 and the fixing spacing between the spanner 2, thereby the size that control is pulled mouthful adapts to the nut of various different sizes.In addition, the utility model only is fit to be useful on just outer five jiaos of nuts.Because the exterior angle of just outer five jiaos of nuts is 108 °, the interior angle of pulling mouth of the present utility model also is 108 °, matches with just outer five jiaos of nuts.In operating process, the mouth of pulling that is equivalent to monkey wrench formation of the present utility model all wraps in the inside with whole just outer five jiaos of nuts, turns in the process, and it is stressed in five angles of nut four angles being arranged.And the screw plate of monkey wrench of the prior art is parallel design, and it is stressed having only two angles in operating process on the nut.By contrast, the utility model is difficult for skidding in operating process and between the nut.In addition, monkey wrench of the present utility model all wraps in the inside, difficult drop-off between monkey wrench and the nut when turning with nut.
As shown in Figure 1, in the utility model operating process, the maximum when turning nut is pulled a mouthful state.
Embodiment as shown in Figure 4 is meant: the outer tooth nut 32 of turn drives half screw rod 13, thereby drives moving of movable jaw 1.Conveniently pull muzzle outside nut, and then the outer tooth nut 32 of rotation, adjustment movable jaw 1 and fixedly the spacing between the spanner 2 adapt to the size of nut.
Embodiment as shown in Figure 3, when in operating process, when the nut that need turn is pulled mouthful less than the maximum of the utility model monkey wrench, only need the outer tooth nut 31 of turn adjust movable jaw 1 and fixedly the spacing between the spanner 2 adapt to the size of nut.
