Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware tool technology, and in particular to a wrench with a rotating handle. Background Technology
[0002] A wrench is a common hardware tool used for removing and installing nuts. It generally includes a long, narrow handle with a locking slot at one end for engaging the nut. This slot may have a hexagonal groove with a side length matching the nut, or claws with a spacing matching the nut. To use it, the locking slot is engaged with the nut, and the handle is rotated continuously to remove or install the nut.
[0003] However, the removal and installation of nuts often require rotating the handle multiple times. Since the human wrist has a limited rotation angle, the removal and installation of nuts often requires the operator to repeatedly loosen and re-grip the handle to change the grip angle. In actual use, this is time-consuming, laborious, and inefficient. Therefore, it is necessary to develop a new type of wrench. Utility Model Content
[0004] The purpose of this invention is to overcome the technical problems of existing wrenches requiring operators to repeatedly adjust the grip angle, which is time-consuming, laborious, and inefficient when disassembling and assembling nuts, and to provide a wrench with a rotating handle.
[0005] In a first aspect, the present invention provides a wrench with a rotating handle, including a handle, one end of which is provided with a locking slot for engaging a nut, and further comprising:
[0006] A swing base, one end of which is swayingly connected to a handle, and the swing base has a gap between itself and the bayonet along the length of the handle;
[0007] The grip is rotatably connected to the end of the swing base away from the handle, and the rotation axis of the grip is set along the length of the grip.
[0008] The swing base can cause the grip to swing relative to the handle, so that the length direction of the grip is parallel to or perpendicular to the length direction of the handle.
[0009] When using the wrench with a rotating handle in this solution, the jaws are first engaged with the nut. Then, the operator holds the handle and adjusts its length direction to be perpendicular to the length direction of the handle by using the swing base. This makes the handle's axis of rotation perpendicular to the handle's length direction, and the handle rotates the handle to remove or install the nut. Since the handle's axis of rotation is parallel to the axis of rotation required for the handle to remove or install the nut, the relative rotation between the handle and the operator's hand can be converted into a relative rotation between the handle and the handle. This allows the operator's hand to remain stationary relative to the handle, eliminating the need to frequently loosen and re-grip the handle to change the grip angle, as is required in existing technologies. This results in more efficient and faster nut removal and installation, while reducing the operator's physical exertion.
[0010] When not using a wrench with a rotating handle according to this solution, the length of the handle can be adjusted to be parallel to the length of the handle by swinging the base. This reduces the space occupied by the handle along the length of the entire solution, making it easier to carry and store.
[0011] Preferably, the handle is provided with a storage groove, the shape and size of which match the shape and size of the grip, and the swing base can swing to cause the grip to retract into or out of the storage groove.
[0012] When not in use, this design allows the grip to be stored in the storage slot, further reducing the space occupied by the grip along the length perpendicular to the handle, making the design more convenient to carry and store.
[0013] Preferably, the bayonet includes at least two hexagonal slots with different side lengths.
[0014] This solution recommends one specific bayonet structure that can directly engage with nuts of corresponding sizes via hexagonal slots. Compared to other forms, such as adjustable wrenches, this solution eliminates the need for adjusting the bayonet size, making it faster and more convenient to use. Furthermore, this solution has at least two hexagonal slots with different side lengths, thus enabling the assembly and disassembly of nuts of at least two different sizes, demonstrating excellent versatility.
[0015] Preferably, the side length of the hexagonal slot away from the swing base is greater than the side length of the hexagonal slot close to the swing base.
[0016] Since larger nuts often require greater torque for disassembly and assembly, this design places the hexagonal slot with a larger side length further away from the swing base. This allows for a larger lever arm when disassembling and assembling nuts of the corresponding size, enabling workers to disassemble and assemble nuts more effortlessly.
[0017] Preferably, the jaw includes two jaws, at least one of which is slidably connected to the handle; the two jaws can move closer or further apart to clamp or release the nut.
[0018] This solution recommends one specific bayonet structure. Compared to other forms, such as open-end wrenches with fixed bayonet sizes, this solution can be adapted to nuts of different sizes by adjusting the distance between the two jaws, thus having greater versatility.
[0019] Preferably, a worm gear is rotatably connected to the handle, and a pawl slidably connected to the handle is provided with worm teeth. The worm gear and worm teeth mesh with each other, and rotating the worm gear can drive the pawl to move closer to or away from the other pawl.
[0020] This solution recommends using a worm gear to drive the movement of the chuck, which utilizes the self-locking characteristic of the worm gear transmission to prevent the chuck from spontaneously changing position under external force, thus preventing the chuck from accidentally loosening the nut.
[0021] Preferably, a hammer head is provided at the end of the handle away from the swing base, and the hammer head and the bayonet are located on opposite sides of the handle.
[0022] This solution adds a hammer head to the wrench, enabling it to function as a hammer in addition to assembling and disassembling nuts. This achieves multi-purpose functionality, eliminating the need for workers to carry a separate hammer, thus reducing their workload and the cost of purchasing maintenance tools.
[0023] Preferably, the end of the hammer head furthest from the handle has an arc-shaped striking surface.
[0024] This solution recommends one specific hammer head shape, which allows workers to hammer workpieces at various angles and reduces the risk of the hammer head damaging the workpiece.
[0025] Preferably, a hammering pad is provided at one end of the handle near the swing base, and the hammering pad protrudes from the surface of the handle.
[0026] This solution adds a hammering pad to the wrench, enabling it to function as a hammering pad in addition to its function of removing and installing nuts, thus achieving multiple uses for the wrench. When it is necessary to hammer fragile or sensitive workpieces, place the end of the wrench with the hammering pad on the workpiece and then strike the wrench. The impact from the wrench will be evenly transmitted to the workpiece through the hammering pad, thereby reducing the risk of workpiece damage.
[0027] Preferably, the number of hammering pads is at least two, and the hammering pads are distributed on opposite sides of the handle.
[0028] This design incorporates hammering pads on both sides of the wrench. When it is necessary to hammer fragile or sensitive workpieces, place the hammering pad on one side of the wrench onto the workpiece and then strike the hammering pad on the other side of the wrench. This allows the impact to be evenly transmitted to the wrench first and then evenly to the workpiece, thereby reducing the risk of damage to both the wrench and the workpiece.
[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0030] This invention provides a wrench with a rotating handle. By connecting a swing base and a handle to the wrench, the relative rotation between the handle and the operator's hand can be converted into relative rotation between the handle and the handle when installing or removing nuts. This allows the operator's hand to remain stationary relative to the handle, eliminating the need to frequently loosen and re-grip the handle to change the grip angle, as is the case with existing technologies. This enables more efficient and faster installation and removal of nuts, while reducing the operator's physical exertion.
[0031] When not using a wrench with a rotating handle according to this solution, the length of the handle can be adjusted to be parallel to the length of the handle by swinging the base. This reduces the space occupied by the handle along the length of the entire solution, making it easier to carry and store. Attached Figure Description

[0045] Example 1
[0046] like Figures 1 to 4 As shown, a wrench with a rotating handle includes a handle 1, a swing base 2, and a handle 3. One end of the handle 1 is provided with a latch for engaging a nut. One end of the swing base 2 is swayably connected to the other end of the handle 1, so that there is a gap between it and the latch along the length direction of the handle 1 as a lever arm, and the axis of the swing base 2 is along the width direction of the handle 1. The handle 3 is rotatably connected to the end of the swing base 2 away from the handle 1, and the axis of rotation of the handle 3 is set along the length direction of the handle 3. The swing of the swing base 2 can drive the handle 3 to swing relative to the handle 1, so that the length direction of the handle 3 is parallel to or perpendicular to the length direction of the handle 1.
[0047] exist Figures 2 to 4 In the diagram, the directions indicated by arrows X, Y, and Z are mutually perpendicular; and the direction indicated by arrow X represents the length direction of handle 1, the direction indicated by arrow Y represents the width direction of handle 1, and the direction indicated by arrow Z represents the thickness direction of handle 1.
[0048] In an optional embodiment, the handle 1 is provided with a storage groove 11, the shape and size of which match the shape and size of the grip 3, thereby enabling it to store at least a portion of the grip 3; the swing base 2 swings to cause the grip 3 to retract into or out of the storage groove 11, for example in Figure 1 In the middle, the length direction of the grip 3 is parallel to the length direction of the handle 1, so that its entire length is located within the storage slot 11; while Figure 2 In the middle, the length direction of the grip 3 is perpendicular to the length direction of the handle 1, so that the entire grip is located outside the storage slot 11, which makes it convenient for the operator to hold.
[0049] In an optional embodiment, the storage slot 11 is a through slot that passes through the handle 1, allowing the grip 3 to swing to both sides of the handle 1 via the storage slot 11, thus facilitating more flexible use of the grip 3 from both sides of the handle 1 by the operator. If only one side of the handle 1 needs to be used for the grip 3, the storage slot 11 can also be a blind slot.
[0050] In an optional embodiment, the swing base 2 and the handle 1 can be connected by a positioning hinge, thereby locking the grip 3 in a position parallel or perpendicular to the length direction of the handle 1, preventing the grip 3 from swinging unrestricted; the positioning hinge can be an existing product.
[0051] In an optional implementation, the bayonet includes at least two hexagonal slots 12 with different side lengths. For example... Figures 1 to 3 As shown, four hexagonal slots 12 are arranged sequentially along the length of the handle 1, and the side lengths of the four hexagonal slots 12 are all different, so that they can be adapted to four different sizes of nuts. The hexagonal slots 12 can be either through slots or blind slots.
[0052] In an optional embodiment, the side length of the hexagonal slot 12 furthest from the swing base 2 is greater than the side length of the hexagonal slot 12 closest to the swing base 2. For example... Figures 1 to 3 As shown, the hexagonal slot 12 closer to the right has a larger side length.
[0053] In an optional embodiment, the edges of the hexagonal slot 12 are chamfered to facilitate guiding the nut when it is engaged with the nut.
[0054] In an optional embodiment, the latch includes two jaws 4, at least one of which is slidably connected to the handle 1, thereby allowing the two jaws 4 to move closer or further apart, thus clamping or releasing the nut. For example Figure 1 As shown, the two jaws 4 are spaced apart, allowing the nut to be loosened or fitted to a larger nut; while Figure 2 The two jaws 4 shown are brought close together, allowing them to clamp the nut or fit a smaller nut. Specific sliding connections include, but are not limited to, hole-shaft clearance fits, slide rail-slider mechanisms, or lead screw-slider mechanisms.
[0055] In an optional embodiment, a worm gear 5 is rotatably connected to the handle 1, and a chuck 4 slidably connected to the handle 1 is provided with worm teeth. The worm gear 5 and the worm teeth mesh with each other, and rotating the worm gear 5 can cause the chuck 4 to move closer to or away from another chuck 4. The specific design of the worm gear 5 and the worm teeth can refer to existing adjustable wrenches.
[0056] In an optional embodiment, a hammer head 13 is also provided at the end of the handle 1 away from the swing base 2, and the hammer head 13 and the bayonet are respectively located on opposite sides of the handle 1 along its width direction. The specific shape of the hammer head 13 includes, but is not limited to, prism, cylinder or frustum shape.
[0057] In an optional embodiment, the end of the hammer head 13 away from the handle 1 is provided with an arc-shaped striking surface. The specific shape of the arc-shaped striking surface includes, but is not limited to, a sphere, a parabola, or a hyperboloid.
[0058] In an optional embodiment, a hammering pad 14 is also provided at one end of the handle 1 near the swing base 2, and the hammering pad 14 protrudes from the surface of the handle 1. The material of the hammering pad 14 includes, but is not limited to, rubber, plastic, wood or copper.
[0059] In an optional embodiment, the number of hammering pads 14 is at least two, and the hammering pads 14 are distributed on opposite sides of the handle 1. For example Figure 3 As shown, a hammering pad 14 is provided on each side of the handle 1 along its width direction.
[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
