Description

Socket wrench

This creation is about a socket wrench that can be directly interchangeable between an opening and a socket.

A wrench is a hand tool that uses the lever principle to turn bolts, nuts and other workpieces that are difficult to turn by hand. A wrench usually has an opening at one or both ends of the handle to clamp the workpiece. The user can turn the workpiece by applying external force in the direction of rotation at the other end of the handle. Among them, adjustable wrenches are widely used because the opening size can be adjusted.

The commonly used adjustable wrench, as shown in FIGS. 1, 2, and 3, mainly comprises a handle 10, a fixed jaw 20, and a movable jaw 30. The fixed jaw 20 is integrally formed at the top of the handle 10, and a rotatable screw rod 40 is disposed transversely. The movable jaw 30 is movably disposed at the top of the handle 10 and can be moved closer to or farther from the fixed jaw 20, thereby adjusting the distance between the movable jaw 30 and the fixed jaw 20. That is, the movable jaw 30 is provided with a tooth bar 31 engaged with the screw rod 40 at the bottom, thereby allowing the user to adjust the distance _W1 between the movable jaw 30 and the fixed jaw 20 by rotating the screw rod 40. , so as to clamp a fixed workpiece 50 such as a nut or a bolt to perform a locking or loosening operation; since the distance _W1 is greater than the clamping edge width _W2 of the workpiece 50, the gaps _S1 and _S2 therein exist, as shown in Figures 3, 4, and 5. When the wrench turns the workpiece 50, the margin (fit tolerance) of the engagement between the movable jaw 30 tooth 31 and the screw rod 40 will enlarge the distance _W1 by a "pushing" action. In this way, the fixed jaw 20 and the movable jaw 30 clamp the workpiece 50 on opposite sides, and the clamped edge of the workpiece 50 receives the force of the fixed jaw 20 and the movable jaw 30 in the form of line contact at the corner 51. When the workpiece 50 is disassembled or locked with force, it is easy to cause the corner 51 to be worn due to slipping. As shown in FIG6, the workpiece 50A with excessively worn corner 51 , which will inevitably affect the twisting firmness or feel of the subsequent wrench tool operation; the most common way to solve this problem is to change the socket wrench and use the socket to forcefully disassemble or tighten the workpiece. However, this way of changing tools requires not only the preparation of different wrench tools, but also the interchangeable use of different tools makes the workpiece disassembly or tightening work a little inconvenient or inconvenient in operation.

The main purpose of this invention is to provide a socket wrench, which is a wrench, including:

A wrench body, with a first jaw at one end of a handle and a second jaw at the other end, a wheel groove is formed through the first jaw and a sliding surface is formed at a front end, a track groove tangent to the wheel groove is formed on the sliding surface and a fixed jaw is formed at one end, the fixed jaw has a first clamping surface perpendicular to the sliding surface, and the second jaw has a U-shaped notch;

A wheel screw is pivotally mounted on the wheel groove;

A movable jaw has a guide plate portion embedded in the track groove, one end of the guide plate portion is formed with a jaw body extending from the sliding surface toward the distal end, and the other end, relative to the gear screw, is formed with a gear row engaged with the gear screw, and the gear screw can be rotated to drive the jaw body along the sliding surface to approach or move away from the fixed jaw; the jaw body has a second clamping surface relative to the first clamping surface and can form a jaw opening with the first clamping surface;

A sleeve joint is pivoted on the U-shaped notch, one end of which has a pivoting portion pivoted with the U-shaped notch and capable of swinging, and the other end of which has a sleeve engaging portion extending outside the U-shaped notch;

Generally, the opening size of the jaw is adjusted by rotating the wheel screw, and the first clamping surface and the second clamping surface of the fixed jaw and the movable jaw clamp the two sides of the hexagonal bolt or nut workpiece, and the handle can be swung to twist the workpiece in a non-forceful manner; when the workpiece is to be disassembled or locked by force, the second jaw end only needs to engage the sleeve that meets the specifications on the sleeve engaging portion of the sleeve joint, and the workpiece can be disassembled or locked by swinging the handle in the manner of using a socket wrench; the overall structure has the convenience or convenience of a single wrench, and the opening and the sleeve can be directly interchanged.

The second purpose of the invention is to provide a socket wrench, wherein the second jaw is horseshoe-shaped, has a pair of bearing arms, and the U-shaped notch is formed by the pair of bearing arms, and a pivot hole is formed on the pair of bearing arms to penetrate each other, and a through-axis hole is provided on the pivot part of the sleeve joint relative to the pivot hole, and a pivot member penetrates the through-axis hole on the pivot hole, and the sleeve joint is pivoted on the U-shaped notch, and the sleeve joint can be swung with the pivot member as the axis, so that the sleeve engaging portion extends outside the U-shaped notch, and can be engaged with the sleeve within a 180-degree swing range; and A deep hole is provided at the bottom of the U-shaped notch formed by the pair of bearing arms, and an elastic member and a steel ball are successively assembled in the deep hole. The pivoting part of the sleeve joint is pivoted on the U-shaped notch, and the bottom end relative to the U-shaped notch is formed into an arc surface. On the arc surface, relative to the deep hole, at least one concave arc groove is provided to form a locking position with the steel ball. The elastic member pushes the steel ball to lock the concave arc groove to limit the free swing of the sleeve joint, so that when the sleeve engaging part is not engaged with the sleeve, the sleeve engaging part can be used in a positioning state of extending flatly out of the U-shaped notch, which is conducive to the flat storage of the wrench.
