Description

Technical Field

[0001] This utility model relates to the field of wrench technology, and in particular to a novel resetting movable wrench. Background Technology

[0002] An adjustable wrench, also known as a variable wrench, is characterized by its ability to change the opening size by adjusting the nut, thus accommodating bolts or nuts of different sizes. This flexibility makes it a common tool in fields such as mechanical repair, automotive repair, and construction.

[0003] Adjustable wrenches in the current technology are generally non-resettable, and after use, they need to be removed and tightened again with the bolt, which is relatively complicated and causes some trouble for people using adjustable wrenches. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology. By using multiple pawls in cooperation with the ratchet, the pawls restrict the position of the ratchet. When force is applied to the handle, the handle will drive the main body to rotate, thereby realizing the rotation of the wrench. This invention proposes a novel resettable movable wrench.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel resettable adjustable wrench includes a main body, a movable groove at the front end of the main body, a movable block slidably connected in the movable groove, a movable head at the upper end of the movable block, an operating groove at the upper end of the main body, an adjusting roller rotatably connected in the operating groove, the adjusting roller cooperating with the movable block, a groove at the rear end of the main body, an adjusting mechanism in the groove, and a limiting mechanism in the groove.

[0007] Preferably, the adjustment mechanism includes a rotating shaft rotatably connected in the groove, a fixed plate on the outer wall of the rotating shaft, and a handle on the side wall of the fixed plate.

[0008] Preferably, the limiting mechanism includes multiple fixing posts disposed in the groove, and each of the multiple fixing posts has a pawl on its outer wall.

[0009] Preferably, the outer wall of the fixed disc is provided with a ratchet, and the plurality of pawls cooperate with the ratchet.

[0010] Preferably, both ends of the plurality of fixing posts are rotatably connected to the upper and lower ends of the groove, and the rotatable connections between the fixing posts and the groove are all elastically connected by torsion springs.

[0011] Preferably, the number of the plurality of fixing columns is five, and the five fixing columns are arranged circumferentially.

[0012] The beneficial effects of this utility model are:

[0013] 1. By using multiple pawls in conjunction with the ratchet, the pawls restrict the position of the ratchet. When force is applied to the handle, the handle will drive the main body to rotate, thereby achieving the rotation of the wrench.

[0014] 2. By causing the ratchet to push multiple pawls to move, the handle is returned to its starting position, thus resetting the handle and making it more convenient for people to use the wrench. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Reference Figure 1-3 A novel resetting adjustable wrench includes a main body 1. A movable groove 4 is provided at the front end of the main body 1, and a movable block 5 is slidably connected in the movable groove 4. A movable head 6 is provided at the upper end of the movable block 5. An operating groove 2 is provided at the upper end of the main body 1, and an adjusting roller 3 is rotatably connected in the operating groove 2. The adjusting roller 3 cooperates with the movable block 5. A groove 7 is provided at the rear end of the main body 1, and an adjusting mechanism is provided in the groove 7. The adjusting mechanism includes a rotating shaft 10 rotatably connected in the groove 7. A fixed plate 9 is provided on the outer wall of the rotating shaft 10, and a handle 8 is provided on the side wall of the fixed plate 9.

[0022] The groove 7 is provided with a limiting mechanism, which includes multiple fixed posts 12 disposed in the groove 7. Each fixed post 12 has a pawl 13 on its outer wall. By causing the ratchet 11 to push the multiple pawls 13 to move, the handle 8 is returned to the starting position, thereby resetting the handle 8 and bringing certain convenience to people in using the wrench.

[0023] The outer wall of the fixed plate 9 is provided with a ratchet 11, and multiple pawls 13 are engaged with the ratchet 11. By engaging multiple pawls 13 with the ratchet 11, the position of the ratchet 11 is restricted by the pawls 13. When force is applied to the handle 8, the handle 8 will drive the main body 1 to rotate together, thereby realizing the rotation of the wrench.

[0024] Multiple fixed posts 12 are rotatably connected at both ends to the upper and lower ends of the groove 7, and the rotatable connection between the fixed posts 12 and the groove 7 is elastically connected by torsion springs 14.

[0025] The number of fixed posts 12 is five, and the five fixed posts 12 are arranged circumferentially.

[0026] When this utility model is used, the multiple pawls 13 cooperate with the ratchet 11 to restrict the position of the ratchet 11. When force is applied to the handle 8, the handle 8 will drive the main body 1 to rotate, thereby rotating the wrench. At this time, when the handle is rotated back, the ratchet 11 pushes the multiple pawls 13 to move under the rotational connection of the multiple fixings 12 and the groove 7, and the elastic action of the torsion spring 14 between the fixings 12 and the groove 7, thereby returning the handle 8 to the starting position and realizing the reset of the handle 8, which brings certain convenience to people in using the wrench.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
