Description

adjustable wrench

This creation is about a hand tool, especially an adjustable wrench that saves time and is easier to handle.

The wrench is a hand tool that uses a lever principle to turn a bolt, a nut, and other objects that are difficult to rotate by hand. The wrench usually has an opening at either end or both ends of the handle portion to hold the object, and the user is at the other end of the handle portion. The object can be rotated by applying an external force in the direction of rotation. There are quite a few types of wrenches, one of which is a spanner wrench, and the use of a spanner wrench is quite high, because it can freely adjust the size of the opening to accommodate multiple sizes of objects, without having to switch to different sizes of objects. Various open end wrenches. For the user, only one adjustable wrench can replace multiple single-size open-end wrenches, which brings great convenience and applicability.

A typical adjustable wrench, such as the U.S. Patent No. 8,136,429, includes a handle portion, a head portion, a sliding jaw, a shaft and a turbine. The head portion is formed at one end of the handle portion and includes a fixed jaw. a sliding rail and a receiving slot, the sliding rod of the sliding jaw is slidably disposed on the sliding rail, the shaft and the worm wheel are accommodated in the pocket, and the worm wheel and the sliding rod are mutually engaged to control the sliding jaw relative to the fixed jaw Thereby, the size of the opening formed between the sliding jaw and the fixed jaw is adjusted to hold the objects of various sizes. However, it is really a nuisance to always mobilize the worm gear and the sliding rod until the opening size is appropriate.

For example, in U.S. Patent No. 2,687,662, the structure includes a body, a movable block and an adjustment member. The movable block is slidably disposed on the body, and the adjusting member is pivotally disposed on the body, and the adjusting member is provided with teeth and meshes with the teeth of the movable block, and the movable block is displaced on the body by rotating the adjusting member. In this way, the opening size of the adjustable wrench can be adjusted to rotate the screw. Furthermore, the system of the present invention has a certain length. When the grip is held by the hand, the adjustment member is away from the grip, so the hand needs to be displaced a large distance on the body, and the thumb of the hand rotates the adjustment member, and the same The adjustment of the adjustment piece for a long time can adjust the opening size, and the operation is quite unsatisfactory.

In another example, the patent includes a body, a movable block, an adjusting member, a belt, a moving member, a first clamping port and a second clamping port. The movable block is slidably disposed on the body. The adjusting member is pivoted on the body. The adjustment member is provided with teeth to mesh with the teeth of the movable block. One end of the belt is sleeved on the adjusting member. The moving parts are fixed at appropriate positions on the belt. When the moving part is displaced, the belt will be driven to move, and the belt will then drive the adjusting member to rotate, and the adjusting member controls the displacement of the movable block relative to the body. The first jaw and the second jaw are relatively close to or away from each other to adjust the relative position to rotate the screw. Furthermore, in this case, the size of the jaw can be adjusted by moving the moving piece for a long time to rotate the screw.

In addition, the Patent No. 101118686 of the Republic of China has a structure including a fixed cymbal, a movable cymbal and a handle, wherein the movable cymbal is slidably disposed on the fixed cymbal, and the handle is rotatably fixed to the fixed cymbal by a latch, and the handle is fixed. The end has a dialing member relative to the movable jaw, and when the handle is rotated relative to the fixed jaw, the movable jaw is slid by the dialing member to slide relative to the fixed jaw, and at this time, the movable jaw is disposed to compress the slot of the spring, and an abutment member is restrained The size of the opening between the fixed raft and the movable raft. Therefore, when the dial member is no longer linked to the movable jaw, the size of the opening between the fixed jaw and the movable jaw can be fixed, and when the dial member is interlocked with the movable jaw, the fixed jaw and the movable jaw can be fitted together.

In summary, the conventional spanner wrench structure must rotatably mobilize its worm wheel and sliding rod, adjusting member, moving member or handle, and these components need to be adjusted in order to make the opening size correspond to the radial length of the nut. The proper position for a long time is neither convenient nor time consuming.

The purpose of this creation is to provide a monkey wrench for adjusting the position of the movable element after adjusting the position of the movable element, so that it can be rotated and locked, even using the key tooth and the movable 颚. The teeth of the teeth are mutually engaged, and the size of the opening can be fixed, which increases the convenience of adjustment.

In order to achieve the above object, the present invention provides a movable wrench including a fixed jaw body and a movable jaw, a fixed jaw body having a fixed jaw, and a chamber formed under the fixed jaw, the chamber including a slide rail and a slide rail The end has an abutting end; the movable element is clamped in the chamber, and the movable chamber is exposed to the movable jaw, opposite to the fixed jaw, and the movable jaw further comprises a shaft and a compression spring sleeved on the shaft, and the shaft Corresponding to the slide, and one end of the compression spring abuts against the flange of the shaft, and the other end abuts against the abutment end, so that the compression spring is compressed when the movable jaw is pushed away from the fixed jaw along the slide.

Of course, in order to enable the wrench to more securely hold the hex nut, the first rack can be disposed on the shaft, and the second rack is disposed on the positioning block of the inner chamber of the wrench, and the second rack corresponds to the first one. The tooth profiles of the racks correspond to each other and can be engaged with each other. Therefore, the hex nut can be held more firmly.

One of the fixed jaws of this creation is further provided with a handle to increase the radius of rotation of the wrench when the hex nut is turned, thereby saving a lot of effort.
