Active wrench's active shifting structure

This creation is about an adjustable wrench, especially an active 颚 shifting structure of an adjustable wrench that can be easily and quickly adjusted.

Hand tools are needed for factory production and maintenance, car group decoration and home, personal DIY and daily maintenance. The adjustable wrench is one of the most commonly used hand tools in the field of hand tools. It has fixed and movable jaws for clamping on one end of the parts to be driven (such as screws, nuts, etc.), while the main part of the adjustable wrench The technical feature is that the distance between the fixed cymbal and the movable cymbal can be adjusted according to the size of the member to be driven to be clamped, and the driven member is detached when the reverse is pulled; and the driven member is locked when the directional pull is performed. Therefore, compared with a socket wrench or a composite wrench of a size to be driven corresponding to a single-size hand tool, the adjustable wrench capable of adjusting the clamping size range according to the size of the member to be driven is undoubtedly suitable for driving in various sizes and sizes. Pieces.

The conventional adjustable wrench structure generally includes a handle, a worm and a movable cymbal. One end of the handle has a fixed cymbal, and at a position adjacent to the fixed cymbal of the handle, a chute is connected a grooving groove is arranged on the surface of the worm, and the worm is disposed in the accommodating groove, and is rotatable relative to the handle in the accommodating groove, and one end of the movable raft is movably disposed in the sliding groove of the handle, and One end corresponds to the fixed cymbal, and the movable cymbal is disposed at one end of the chute has a plurality of racks, and the rib of the worm is engaged in the rack of the movable cymbal in the accommodating groove, therefore, When the worm rotates in the accommodating groove, the rack can be driven by the rib to drive the movable cymbal to move toward or away from the fixed cymbal, thereby adjusting the distance between the movable cymbal and the fixed cymbal.

However, the above-mentioned setting method of the adjustable wrench has many disadvantages in use, for example, by rotating the worm to move the movable cymbal, because the contact area between the rib of the worm and the movable cymbal is small, and the spiral The arrangement of the tooth pattern is easy to cause the rotation path to be long, and the movement of the activity in the sliding groove is slow, which causes the user to spend a considerable amount of time on the movable 颚 relative fixed 颚 distance, and the use efficiency is obviously poor. In addition, since the user must push the worm by the friction between the finger and the rib of the worm, the operation is not only unsatisfactory, and the user's finger is easily injured, so that it is necessary to improve.

The creator has the shortcomings of the use of the adjustable wrench structure, which has the disadvantages of inefficient use and unsatisfactory operation. It is the idea of creating and testing the sample, and after many revisions and improvements, creation.

The present invention provides an activity 颚 shifting structure of a movable wrench, wherein the adjustable wrench comprises: a handle, a movable cymbal, a top cymbal group, an adjustment group and a cover, wherein the handle has a driving head at one end, The driving head is provided with a fixing cymbal, a sliding slot extending through the fixing cymbal and a slot chamber communicating with the sliding slot, and the movable cymbal end is provided with a slider with a plurality of ratchets slidingly disposed in the sliding slot of the handle driving head The top set includes a top member and a first elastic member. The top member is coupled to the first elastic member and disposed in the slot of the handle. In the normal state, the top jaw is movable to the ratchet, so that the movable jaw is movable. The adjustment group includes a trigger rod, a torsion spring, a dialing member and a second elastic member. The trigger rod is coupled to the torsion spring pivot group on the grip driving head, and the trigger rod is disposed at one end. An actuating portion is placed in the slot chamber of the handle driving head, and the other end is provided with a turning portion extending from the grip The handle is driven outside the slot of the handle, and the dial member is coupled to the second elastic member and disposed on the actuating portion of the trigger rod for driving through the trigger lever to move the movable jaw to the fixed jaw direction to adjust the movable jaw and fix. The distance between the jaws covers the slot of the handle.

The main purpose of this creation is that when it is used, it only needs to force the lever of the adjustment group to quickly adjust the movement of the activity to the fixed direction, thereby effectively improving the use efficiency.

The second purpose of the creation is that when it is used, the force is set to pull the wrench set on the grip driving head, and the driving member moves the movable jaw to the fixed 颚 direction, so that the operation is convenient and convenient. Hand operation, easy to use, and will not cause injury to the user's fingers.
