Description

Technical Field

[0001] This utility model relates to the field of hand tool technology, and more specifically to a quick-turning wrench. Background Technology

[0002] Socket wrenches on the market are generally divided into ratchet wrenches, cross wrenches, and rotary handle wrenches. When using these tools, they are either used with a socket or directly placed on workpieces such as screws. Tightening or loosening the screw or workpiece is achieved by pushing the handle, requiring repeated operations to complete the task. This process is physically demanding and time-consuming, lacks flexibility, and cannot meet the requirements of emergency situations or overly tight workpieces. To solve this problem, a quick-acting wrench has been developed. When used with a socket, turning the handwheel tightens or loosens the workpiece a second time by sliding the handwheel within its helical groove. This tool saves time and effort, is flexible in operation, and better meets usage requirements. Summary of the Invention

[0003] The purpose of this utility model is to provide a quick-acting wrench to solve the above-mentioned technical defects, and to provide a screwing tool that can be used to screw workpieces by rotating a handwheel and in conjunction with a socket, with a novel structure, simple and convenient use, and easy production and processing.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a quick-acting wrench, including a steel ball, a connecting rod, a handwheel, a screw, a nut, a limit nut, a handle, a pin, a sleeve, and a grip. The connecting rod has a countersunk hole at its head and a threaded countersunk hole at its tail, with a spiral groove on the side of the tail. The steel ball is disposed in the countersunk hole at the head of the connecting rod. The handwheel has a through hole in its middle and a threaded through hole on the side of the through hole. The tail of the connecting rod passes through the through hole of the handwheel. The nut is screwed onto the screw and screwed into the threaded through hole of the handwheel, passing through the threaded through hole and protruding for a certain length. Within the spiral groove at the tail of the connecting rod, the connecting rod and the handwheel are movably connected via a screw. The limiting nut has a second threaded through hole in its center. The handle has a threaded head and an annular groove at its tail. Its head passes through the second threaded through hole of the limiting nut and is screwed into the countersunk hole at the tail of the connecting rod. The connecting rod, the limiting nut, and the handle are fixedly connected. The sleeve is a hollow structure with a second through hole on one side of its tail. The pin passes through the through hole on the side of the sleeve and is positioned within the groove at the tail of the handle. The sleeve and the handle are movably connected, and the handle is fixedly connected to the outside of the sleeve. During operation, the head of the connecting rod is inserted into the sleeve, and the handwheel is close to the limiting nut. When the sleeve is fitted onto the workpiece, the handwheel is quickly rotated. The handwheel moves along the spiral groove from the side of the limiting nut to its limit position, generating an impact force that causes the workpiece to rotate rapidly. Then, the handwheel is manually rotated, causing the connecting rod to rotate synchronously, generating a second force, thereby achieving the purpose of tightening or loosening the workpiece.

[0005] The positive effects of this utility model are: a novel structure for a quick-turning wrench, simple and convenient to use, easy to manufacture and process, and through the setting of the spiral groove and handwheel, two-stage force can be generated, which reduces working time and physical exertion after being applied to the workpiece.

[0014] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The following describes a quick-release wrench: It includes a steel ball 1, a connecting rod 2, a handwheel 3, a screw 4, a nut 5, a limiting nut 6, a handle 7, a pin 8, a sleeve 9, and a handle 10. The connecting rod 2 has a countersunk hole 21 at its head and a threaded countersunk hole 22 at its tail. A spiral groove 23 is also provided on the side of the tail. The steel ball 1 is disposed within the countersunk hole at the head of the connecting rod 2. The handwheel 3 has a through hole 31 in its middle and a threaded through hole 32 on the side of the through hole. The tail of the connecting rod 2 passes through the through hole 31 of the handwheel 3. The nut 4 is screwed onto the screw 5 and screwed into the threaded through hole 32 of the handwheel 3, passing through the threaded through hole 32 and protruding for a length. A spiral groove 23 is provided at the tail of the connecting rod 2. Within the groove 23, the connecting rod 2 and the handwheel 3 are movably connected by the screw 4. The limiting nut 6 has a threaded through hole 61 in the middle. The handle 7 has a thread 71 at the head and an annular groove 72 at the tail. Its head passes through the threaded through hole 61 of the limiting nut 6 and is screwed into the threaded countersunk hole 22 at the tail of the connecting rod 2. The connecting rod 2, the limiting nut 6, and the handle 7 are fixedly connected. The sleeve 9 is a hollow structure with a through hole 91 on one side of its tail. The pin 8 passes through the through hole 91 on the side of the sleeve 9 and is set in the groove 72 at the tail of the handle 7. The sleeve 9 and the handle 7 are movably connected. The handle 10 is fixedly connected to the outside of the sleeve 9. During operation, the head of the connecting rod 2 is inserted into the sleeve, and the handwheel 3 is close to the limiting nut 6. When the sleeve is fitted onto the workpiece, the handwheel 3 is rotated quickly. The handwheel 3 moves from one side of the limiting nut 6 to the limit position along with the spiral groove 23. At this time, an impact force is generated, which can drive the workpiece to rotate rapidly. Then, the handwheel 3 is rotated manually, which drives the connecting rod 2 to rotate synchronously, generating a second force, thereby achieving the purpose of tightening or loosening the workpiece.
