Description

Technical Field

[0001] This utility model relates to the field of dual-purpose wrench technology, and in particular to a measuring type dual-purpose wrench with a scale. Background Technology

[0002] A dual-purpose wrench is a tool that combines the functions of an open-end wrench and a box wrench. Because one end is the same as a single-ended open-end wrench and the other end is the same as a box wrench, it has two different functions. Both ends can be used to install and remove screws, except that one end is open and the other end is closed. Wrenches designed in this way, which combine the advantages of two types of wrenches, have great advantages in handling some parts. They can be used for nuts and bolts of different shapes and can quickly switch between open-end and box-end wrenches. Existing dual-purpose wrenches have relatively limited functionality, only suitable for tightening two types of nuts or bolts. Some wrenches have embedded scales in their straight handles for combined use, increasing their functionality. However, the wrenches at both ends of the handle affect the range of the scale, which is quite limiting. Furthermore, due to the wrench length limitation, the corresponding measurement distance is also short, resulting in poor auxiliary measurement. In addition, adding scales also affects the comfort of holding the handle and the operating feel. Utility Model Content

[0003] The purpose of this utility model is to provide a measuring dual-purpose wrench with a scale, which can realize long-distance measurement operations, and the pulled-out measuring strip can be used for free measurement without being affected by the wrench. It can also automatically retract and rewind after being released, improving its auxiliary measurement range and flexibility. In addition, it can effectively reduce the foreign object feeling when holding it and maintain stable operation.

[0004] To achieve the above objectives, a measuring type dual-purpose wrench with a scale is provided, comprising: a handle; a wrench head fixedly connected to the left side of the handle; a curved plate fixedly connected to the right side of the handle; a wrench head fixedly connected to the right side of the curved plate; a mounting groove on the top left side of the handle; a spool embedded in the mounting groove; the spool engaging and fixedly engaged with the handle downwards; a spring mounted inside the spool; a measuring belt fixedly connected to the outer edge of the spring; the measuring belt being wound in layers within the spool and sliding out to the right from the front side of the spool accordingly; and the measuring... The right end of the tape slides through the handle and the curved plate, and a locking rod is fixedly connected to it. An arc-shaped locking plate is fixedly connected to the front side of the locking rod, and a push bar is fixedly connected to the left front end of the arc-shaped locking plate. By setting an internal drum and cooperating with a spring to automatically wind up the measuring tape, long-distance measurement operations can be achieved. The pulled-out measuring tape can be freely measured without being affected by the wrench, and can automatically retract and wind up after being released, improving its auxiliary measurement range and flexibility. In addition, the internal sliding design can maintain the relative integrity of the wrench handle, effectively reducing the foreign object feeling when holding it and maintaining stable operation.

[0005] According to the aforementioned measuring type dual-purpose wrench with a scale, the arc-shaped locking plate, together with the insert rod, slides to the left and embeds into the inner wall of the curved plate and the handle. This ensures that, in its idle state, all parts except the push bar are fully engaged with the handle and curved plate, maintaining its overall appearance and ensuring a comfortable grip.

[0006] According to the aforementioned measuring and adjustable wrench with a scale, the push bar is in the shape of an elliptical cross-section cylindrical tube, and an anti-slip rubber pad is fixedly attached to its left side. This facilitates the easy removal and use of the measuring tape by pressing the push bar from left to right.

[0007] According to the aforementioned measuring wrench with a graduated scale, the front side of the measuring band is respectively equipped with millimeter-level and centimeter-level graduations. Different sides can be selected for flexible measurement operations based on the required measurement accuracy.

[0008] According to the aforementioned measuring dual-purpose wrench with a scale, a damping cap is slidably embedded in the top of the mounting groove corresponding to the handle. This seals and isolates the roll, preventing moisture from entering and causing corrosion of its internal structure, which would affect the pulling out and winding of the measuring tape.

[0009] According to the aforementioned measuring and dual-purpose wrench with a scale, the top of the damping cover has several symmetrically arranged cross-shaped disassembly slots. This facilitates the quick removal of the damping cover using a hook tool for inspection or replacement of the drum.

[0010] The above-mentioned solution has the following beneficial effects: In this invention, a built-in drum combined with a spring-loaded automatic winding measuring belt enables long-distance measurement operations. The pulled-out measuring belt can be used for free measurement without being affected by the wrench, and it can automatically retract and rewind after being released, improving the range and flexibility of its auxiliary measurement. In addition, the built-in sliding design can maintain the relative integrity of the wrench handle, effectively reducing the foreign object feeling when holding it and maintaining stable operation.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
