Description

Technical Field

[0001] This utility model relates to the field of wrench technology, and in particular to a multi-purpose adjustable wrench. Background Technology

[0002] A wrench is a tool used to tighten or loosen bolts. It comes in different sizes and types. Wrenches are made of carbon or alloy structural steel and have openings at one or both ends to hold bolts so as to loosen or tighten them.

[0003] Existing wrenches have limited functionality and cannot assist in loosening operations. For example, it is very difficult to loosen a very tight bolt directly. However, if you first use a hammer to tap the bolt from the side, the vibration generated by the tapping will reduce the bolt's tightening force, making it much easier to loosen with a wrench. Therefore, we propose a multi-purpose adjustable wrench to solve the above problems. Utility Model Content

[0004] This utility model provides a multi-purpose adjustable wrench, which solves the technical problem of the current wrench having only one function.

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-purpose adjustable wrench, including a handle, a fixed head and an adjustable head are provided on the top of the handle, a protrusion is provided between the fixed head and the handle near the fixed head, and a hammer-shaped block is detachably provided on one side of the protrusion.

[0006] Preferably, a threaded hole is provided on one side of the protrusion, and a threaded post is fixed on the side of the hammer block near the threaded hole.

[0007] The above technical solution is adopted: by opening a threaded hole on one side of the protrusion, and fixing a threaded post on the side of the hammer block near the threaded hole, it is convenient to disassemble and install the hammer block and the protrusion, thereby improving the versatility of the wrench.

[0008] Preferably, the end of the hammer-shaped block away from the threaded post is provided with a plurality of anti-slip grooves along the circumference of the hammer-shaped block.

[0009] The above technical solution is adopted: several anti-slip grooves are opened along the circumference of the hammer block at the end away from the threaded column, so that the hammer block can be easily turned by hand when it is threadedly connected to the protrusion.

[0010] Preferably, a first plane is provided on one side of the protrusion, and a second plane is provided on the side of the hammer-shaped block near the threaded post.

[0011] The above technical solution is adopted: a first plane is provided on one side of the protrusion, and a second plane is provided on the side of the hammer block near the threaded column. When the hammer block is fully tightened on the protrusion, the first plane and the second plane are in close contact, which can protect the threaded column and the threaded hole when the hammering function is performed.

[0012] Preferably, the length of the threaded post is the same as the depth of the threaded hole.

[0013] The above technical solution is adopted: by making the length of the threaded post the same as the depth of the threaded hole, the first plane can fit and contact the second plane when the hammer block is tightened, thereby protecting the threaded post and the threaded hole.

[0014] Preferably, the diameter of the threaded post is smaller than the diameter of the end of the hammer block near the threaded post.

[0015] The above technical solution is adopted: the diameter of the threaded post is smaller than the diameter of the end of the hammer block near the threaded post.

[0016] Preferably, the handle is fitted with an anti-slip sleeve, which is made of rubber material.

[0017] The above technical solution is adopted: the handle is covered with an anti-slip sleeve made of rubber material, which makes it easy to hold the handle. The contact between the hand and the anti-slip sleeve makes it easier to use the wrench.

[0018] Preferably, the bottom of the handle is also provided with a round hole.

[0019] The above technical solution is adopted: a round hole is also provided at the bottom of the handle, through which a safety rope can be threaded and attached to the body to prevent the wrench from falling off when used at a height.

[0020] Preferably, the fixing head, the protrusion, and the handle are integrally formed.

[0021] The above technical solution improves the strength of the wrench by integrating the fixing head, protrusion, and handle into a single unit.

[0022] Preferably, the fixed head and the movable head are provided with anti-slip teeth on their corresponding surfaces along the length direction of the fixed head and the movable head.

[0023] The above technical solution is adopted: anti-slip teeth are provided on the corresponding surfaces of the fixed head and the movable head along the length direction of the fixed head, so that the wrench will not slip with the bolt when loosening or tightening the bolt.

[0024] Compared with related technologies, this utility model has the following beneficial effects:

[0025] 1. Compared with traditional wrenches, this utility model features a hammer-shaped block and a handle. The top of the handle has a fixed head and a movable head. A protrusion is located near the fixed head between the fixed head and the handle. The hammer-shaped block is detachably mounted on one side of the protrusion. When loosening a tightly tightened bolt, the hammer-shaped block can be tightened onto the handle by hand first. Then, the bolt's side and circumference can be tapped using the handle and the hammer-shaped block. The vibration generated by tapping the bolt reduces the tightening force. After removing the hammer-shaped block, the bolt can be easily loosened with the wrench, thus improving the wrench's practicality and functional versatility. Attached Figure Description
