Description

Technical Field

[0001] The invention discloses a novel adjustable universal spanner, and relates to the technical field of spanners. Background Art

[0002] In the process of mechanical processing, equipment maintenance and assembly operations, wrenches are the most common installation and disassembly tools. They are convenient for tightening bolts, screws and other threaded fastening bolts. Wrenches usually apply external force on the handle to tighten bolts, screws and other threaded fastening bolts. However, traditional wrenches have relatively single functions. One wrench can only correspond to one nut. Even for adjustable wrenches, the size of the pliers head needs to be adjusted. At the same time, the pliers head is easy to loosen in the working state, which not only causes slippage and nut twisting, but also reduces work efficiency. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a new adjustable universal wrench, and the specific technical solution is as follows:

[0004] A novel adjustable universal wrench comprises a handle, one end of which is provided with a gear, both sides of which are rotatably connected to a movable head of the wrench via a connecting shaft, one side of which is provided with a fixed pliers head, the gear is simultaneously meshed and connected with a rack movable rod, one side of which is fixedly connected to the movable pliers head, and the rack movable rod is slidably connected to the movable head of the wrench.

[0005] Preferably, the movable head of the wrench includes a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are respectively rotatably connected to both sides of the gear, a fixed pliers head is provided on one end side of the first connecting plate and the second connecting plate, and symmetrically arranged sliders are provided at the ends of the first connecting plate and the second connecting plate, and the movable head of the wrench is slidably connected to the movable rack rod through the slider; the fixed pliers head, the first connecting plate, the second connecting plate and the slider are integrally formed.

[0006] Furthermore, two upper and lower sliding grooves are formed at the connection between the rack movable rod and the movable clamp head for sliding connection with the sliding block.

[0007] Preferably, the fixed clamp head and the movable clamp head are arranged opposite to each other, and their inner surfaces are both smooth planes to facilitate tightening of bolts or screws.

[0008] Preferably, the handle is provided with an anti-slip portion.

[0009] The present invention can twist bolts, screws and other threaded fastening bolts of various specifications by adjusting the movable pliers head, and the bolts or nuts can be rotated by rotating the clamping screw through the handle. During the twisting process, the force direction of the handle is opposite to the direction of the clamping force of the jaws, thereby ensuring the reliability of the twisting.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1-4 As shown, a new type of adjustable universal wrench includes a handle 1, one end of the handle 1 is provided with a gear 2, both sides of the gear 2 are rotatably connected to a wrench movable head 3 through a connecting shaft 7, one side of the wrench movable head 3 is provided with a fixed pliers head 6, the gear 2 is also meshed and connected with a rack movable rod 4, one side of the rack movable rod 4 is fixedly connected to an movable pliers head 5, and the rack movable rod 4 is slidably connected to the wrench movable head 3. The fixed pliers head 6 and the movable pliers head 5 are arranged opposite to each other, and their inner surfaces are both smooth planes for convenient tightening or loosening of bolts, screws and other threaded fastening bolts. The handle 1 is provided with an anti-slip portion 10, and the anti-slip portion 10 is an anti-slip rubber sleeve.

[0017] The movable head 3 of the wrench includes a first connecting plate 301 and a second connecting plate 302, which are rotatably connected to the two sides of the gear 2, and a fixed pliers 6 is provided on one end side of the first connecting plate 301 and the second connecting plate 302, and a symmetrically arranged slider 8 is provided at the ends of the first connecting plate 301 and the second connecting plate 302, and the movable head 3 of the wrench is slidably connected to the rack movable rod 4 through the slider 8; the fixed pliers 6, the first connecting plate 301, the second connecting plate 302 and the slider 8 are integrally formed. The connection between the rack movable rod 4 and the movable pliers 5 forms two upper and lower slide grooves 9 for slidably connecting with the slider 8.

[0018] Through the cooperation of the slider 8 and the slide groove 9, the rack movable rod 4 and the movable pliers head 5 can slide on the wrench movable head 3, and the gear 2 can rotate on the rack movable rod 4. The rotation angle of the handle 1 is adjusted to drive the gear 2 to rotate, so that the rack movable rod 4 and the movable pliers head 5 can move on the wrench movable head 3, thereby adjusting the size of the wrench opening, and can clamp and loosen bolts, screws and other threaded tightening bolts of various specifications.

[0019] During the twisting process, the handle 1 rotates clockwise, driving the gear 2 to rotate clockwise, driving the rack movable rod 4 and the movable clamp head 5 to perform clamping movement. Through the coordination of the gear and rack, the force direction of the handle 1 is opposite to the direction of the clamping force of the jaws, which can ensure the reliability during twisting. At this time, the nut is clamped very firmly and stably, and the wrench will not be detached from the nut.

[0020] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
