Abstract

An open-end wrench comprises a fixed jaw, a handle pivotably secured to the fixed jaw, and a moveable jaw. An inclined hole is through the fixed jaw. A spring biased hollow cylinder extends from the moveable jaw into the inclined hole. A pin is inserted through a through hole and a slot into the hollow cylinder. Thus, the moveable jaw can move relatively to the fixed jaw by disposing the pin from one position of the slot to another position thereof. The moveable jaw has two force exertion angles to cooperate with three surfaces of the fixed jaw, thereby fastening a fastener.

Description

 Open end wrench  

The invention provides a technical field of a wrench, in particular to an open-end wrench, which is easy to slide between a movable clamp and a fixed clamp with a cylindrical tube and a circular hole, and the cylindrical tube has to be assembled first, which is still easy. Set the spring bolts.

According to U.S. Patent No. 6,202,516, "UNIVERSAL SELF-ADJUSTING WRENCH" patent, which uses a fixed block to hold a spring, and then the screw is inserted through the head of the wrench and the spring to lock it. Block, the head of the wrench is provided with a slot for the fixed block to slip therebetween, and a U-shaped bracket is arranged to frame the inactive opening portion of the slot, but because of the U-shaped bracket, the components are quite large. Complex, its electroplating after processing also makes it difficult to control or control the assembly tolerance between multiple components, and the action surface of the fixed block and the action surface of the wrench head only surround the screw head end or one half of the nut Therefore, if the slippage condition often causes the screw head end or the nut corner to collapse, the conventional US patent case still has room for improvement.

In addition, the invention patent of the "opening wrench" of the national patent application No. 096130113, although there are not many components, the sliding groove and the pivot ear are both parts of finishing, so the electroplating after processing also makes it more The assembly tolerances between components are difficult to control or control, so there are two problems that cannot be assembled or the clearance tolerance is too large. The biggest problem is that the elastic element is placed in the long perforation, and the movable clamp is placed on both sides. The insertion of the chute covers the elastic element, on the one hand, although the elastic element can be restricted, on the other hand, the pivot is difficult to assemble, because the hole is small and it is difficult to operate the tool to compact the elastic element, and the active surface of the movable clamp and the retaining clip颚The action surface only surrounds the screw head end or one half of the nut. Therefore, if the slip condition often causes the screw head end or the nut corner to collapse, the conventional invention patent is still improved. space.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, the consumers are eagerly awaiting, and the relevant industry must strive to develop the goal and direction of breakthrough.

In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the inventor has finally obtained the practical invention.

The main object of the present invention is to provide an open-end wrench, which is arranged with a cylindrical tube and a circular hole between the movable clamp and the fixed clamp, and is easy to be slidably assembled. The cylindrical tube is first assembled with a bolt and the pin is fixed to the fixed clamp. After that, the screw hole at the bottom end of the cylindrical tube is still easy to set the spring bolt, and the fixed clamp and the movable clamp have the action range of two angles and three faces, which can make the operation more stable and avoid the slip condition. .

In order to achieve the above object, the present invention provides an open-end wrench, comprising: a fixed clamp, wherein a fixed hole is obliquely disposed through a circular hole, a movable clamp, and a cylindrical tube is obliquely disposed at a bottom side of the movable clamp; The cylindrical tube is inserted into the circular hole, and the cylindrical tube is radially disposed through the long slot. The radial position of the fixed clip is aligned with the circular hole. A pin hole is formed through the circular hole, and the pin hole is also aligned with the cylindrical tube. Long slot, a pin is worn when the cylindrical tube group enters the round hole, and is inserted through the pin hole and the long slot hole to fix the movable clamp, which can only slide and not swing, and the cylindrical tube forms a bottom end. Screw hole, and after the pin is fixed, it can be easily filled into the spring and locked into the screw hole to fix the position of the spring. The fixed clamp and the top of the movable clamp are provided with an arc hook to make each The clamps have a range of two angles and three faces to avoid slippage.

The above-mentioned objects, structures and features of the present invention will be described in detail with reference to the preferred embodiments of the present invention. .

The present invention provides a designer of an open ended wrench.

In order to enable the reviewing committee to have a better understanding and understanding of the purpose, features and functions of the present invention, the embodiments and the drawings are described in detail as follows: Referring to the first to fifth figures, the present invention provides an open end wrench. The utility model comprises: a fixed clamp 10, a movable clamp 20 and a handle 30; the main component is: a circular hole 11 obliquely disposed through the fixed clamp 10, and the bottom side of the movable clamp 20 is obliquely arranged a cylindrical tube 21, the cylindrical tube 21 is inserted and slidably inserted into the circular hole 11, the cylindrical tube 21 is radially disposed through a long slot 211, and the fixed clamp 10 is arranged to align with the radial position of the circular hole 11 a pin hole 12 of the circular hole 11 , the pin hole 12 is also aligned with the long slot hole 211 of the cylindrical tube 21 , and a latch 40 . The plug pin 40 is worn when the cylindrical tube 21 is assembled into the circular hole 11 . And passing through the pin hole 12 and the long slot 211 to be fixed, so as to restrict the movable clip 20 from sliding only without swinging, the cylindrical tube 21 forms a screw hole 212 at the bottom end, and is able to be inserted into the pin. 40 After the fixing is completed, it is easy to fill in a spring 50 and lock it into one.
