Description

Adjustable wrench structure

The invention relates to the structure of the adjustable wrench, in particular to a movable wrench structure which is provided with a first adjusting member, a second adjusting member and a moving member to adjust the size of the jaw.

As is known in the prior art, a conventional spanner wrench structure, such as U.S. Patent No. 2,687, 662, which is provided with a body 10; a movable block 13 which is slidably disposed on the body 10; an adjusting member 17, the adjustment The member 17 is pivotally disposed on the body 10, and the adjusting member 17 is provided with teeth to mesh with the teeth of the movable block 13; by rotating the adjusting member 17, the movable block 13 is displaced on the body 10, thereby adjusting the adjustable wrench. Rotate the screw with the size of the jaws.

However, the lack of this patent is that the body 10 is provided with a certain length. When the grip is held by the hand, the adjusting member 13 is away from the grip, and the hand needs to be displaced by a large distance on the body 10, the hand The thumb can be rotated to the adjustment member 17, which is quite unsatisfactory during operation, and only the adjustment member 17 can be adjusted to adjust the size of the jaw. Only one size adjustment structure is adjusted without expansion.

For example, in U.S. Patent No. 3,386,432, the structure of the patent system is provided with a body 10; a movable block 16 which is slidably disposed on the body 10; an adjusting member 19 which is pivotally mounted on the body 10, The adjusting member 19 is provided with teeth to mesh with the teeth of the movable block 16; a belt 25, the belt One end of the 25 sleeve is sleeved on the adjusting member 19; a moving member 33 is fixed at a proper position of the belt 25; when the moving member 33 is displaced, the belt 25 is driven to move, and the belt 25 drives the adjusting member 19 to rotate. The adjusting member 19 then controls the movable block 16 to be displaced relative to the body 10. The first jaw 12 and the second jaw 16 are relatively close to or away from each other to adjust the relative position to rotate the screw.

The advantage of the adjustable wrench is that the movable wrench of the patent can rotate the screw by adjusting the size of the jaw by moving the moving member 33. When the hand is held by the grip of the body 10, the moving member 33 The position is closer to the thumb of the hand, and the size of the jaw can be adjusted after the hand is slightly displaced by a small distance. The adjustment is more ergonomic, and the system is 3,348,432 with respect to the progress of 2,687,663.

However, the lack of structure of this patent is based on:

1. The conventional adjustable wrench is the same as the rotary adjustment member 17 of the U.S. Patent No. 2,687,663. However, the U.S. Patent No. 3,348,432 can only displace the moving member 33, and the U.S. Patent No. 3,386,432 is incapable of having the operational mode of the conventional adjustable wrench.

2. U.S. Patent No. 3,348,432 is only an adjustment structure for shifting the moving member 33 and rotating the adjusting member 19 sealed inside the body, and the use is less expandable.

3. The main body 10 is provided with a first notch 21 for accommodating the adjusting member 19, and a second notch 26 for receiving the belt 25, and the first notch 21 and the second notch 26 are in communication with each other. In this way, the first notch 21 and the second notch 26 are in communication, that is, the connection between the belt 25 and the adjusting member 19 is a knot. At the weakest point, when the movable wrench rotates the screw, the body 10 is easily broken there.

In view of the above-mentioned conventional adjustable wrench structure, the inventors have years of experience in related industries, and finally have a product that can solve the drawbacks of the active wrench structure.

The problem to be solved by the invention is that the movable wrench structure of the present invention is provided with a first adjusting member, a second adjusting member and a moving member, and has a plurality of adjustments, in view of the fact that the conventional adjustable wrench has only one adjustable size of the movable wrench. The size of the jaws.

Technical means for solving the problem: a movable wrench structure, comprising: a system having a sliding groove, a first receiving groove, a second receiving groove, a third receiving groove, a first pivoting groove and a second pivoting groove; The block is provided with a sliding portion, and the sliding portion is sleeved in the sliding groove, the sliding portion is provided with a first tooth portion; a first adjusting member is pivotally disposed in the first receiving groove, and the first adjusting member is peripherally The second tooth portion is provided to be engaged with the first tooth portion; a second adjusting member is pivotally disposed in the second receiving groove; a linking member is received in the third receiving groove; and a moving member is coupled On the linking member, the moving member is disposed on the upper side of the body; a first coupling member is pivotally disposed at the first pivoting slot, and the first coupling member is respectively coupled to the first adjusting member and one end of the linking member; The second coupling member is pivotally disposed at the second pivoting groove, and the second coupling member is coupled to the second adjusting member and the other end of the linking member.

Compared with the effect of the prior art: when the position of the movable member is adjusted, the second adjusting member is rotated to drive the second coupling member to rotate, and the linking member is actuated to rotate the first coupling member and the first adjusting member, and the adjusting member can control the movable member. Displace the body, adjust the size of the jaw and rotate the screw of the same specification. Similarly, move the moving part provided on the body. The moving part drives the linkage to move, so the jaw can be adjusted. Dimensions, of course, the first adjustment member can be directly rotated to adjust the size of the jaws. The present invention has a plurality of adjustment jaws at the size structure, and is operated more. The position of the second adjusting member is quite close to the grip of the body. When the hand is held at the grip, the hand does not need to move or only needs to move a minimum distance to contact the second adjusting member and rotate the second adjusting member. The operation is more convenient.
