Abstract
Description
Technical Field
[0001] The present application relates to the technical field of tightening tools, and in particular to a tightening tool for a fan. Background Art
[0002] During the installation and maintenance of fans, it is often necessary to tighten nuts of different sizes. Traditional tightening tools usually adopt a fixed design, and the clamping size of the pliers is limited, which cannot adapt to nuts of various sizes. This causes the workers to carry a variety of tightening tools of different sizes during operation, which increases the complexity and inconvenience of the work. Utility Model Content
[0003] The problem to be solved by the present application is that, due to the limited clamping size of the pliers head of the existing tightening tools, it is necessary to carry a variety of tightening tools of different sizes during the fan installation process, which increases the complexity and inconvenience of the work.
[0004] In order to solve the above-mentioned technical problems, the present application provides a tightening tool for a fan, comprising two pliers handles hinged by rivets, and pliers heads for clamping operations are arranged at the ends of the pliers handles. A straight slot for the rivet to slide inside the slot is provided at a hinged position on the upper part of one of the pliers heads, and the clamping distance between the pliers heads is expanded by sliding the rivet inside the straight slot.
[0005] Since the tightening tool of the present application is designed with a pliers head having a straight slot, the clamping distance between the two pliers heads can be expanded by sliding the rivet inside the straight slot, thereby solving the problem of the tightening tools in the prior art that, due to the limited clamping size of the pliers head, a variety of tightening tools of different sizes need to be carried during the fan installation process, increasing the complexity and inconvenience of the work.

[0013] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example
[0014] The present application relates to a tightening tool for a fan, such as Figure 1-6 As shown, the tightening tool includes two clamp handles 1 hinged by rivets 4, and the ends of the clamp handles 1 are arranged with clamp heads 2 for clamping operation. In order to expand the clamping size of the clamp heads 2, a straight slot 5 for sliding the rivet 4 inside is provided at a hinged position on the upper part of one of the clamp heads 2, so that the clamping spacing between the two clamp heads 2 can be changed by adjusting the relative position between the straight slot 5 and the rivet 4. In order to avoid the clamp heads 2 shaking during the clamping operation due to the arrangement of the straight slot 5, so that an effective torque force cannot be applied to the nut, a plurality of racks 6 for spacing positioning operation are evenly and spacedly arranged on both sides of the straight slot 5, and a clamp ring 8 adapted to the rack 6 is arranged on the upper part of the other clamp head 2, so that by sliding the clamp ring 8 between the racks 6, relative displacement can no longer occur between the straight slot 5 and the rivet 4, and then a relatively stable hinged state is formed between the clamp heads 2, so that an effective torque force can be applied to the nut.
[0015] In order to reduce the slipping of the pliers head 2 during the clamping process, pliers teeth 7 with anti-slip function are evenly arranged on the upper part of the pliers head 2.
[0016] In order to fully exert the torque effect of the pliers handle 1, a contact 3 protruding outward is formed at one end of the upper part of the pliers handle 1. The position of the contact 3 is the closest position for holding the pliers handle 1. When the pliers handle 1 is held beyond the contact 3, the torque force required for clamping the pliers head 2 will be greatly increased. On the other side of the contact 3, the required torque force can be effectively reduced by increasing the torque length.
[0017] When in use, according to the size of the nut to be clamped, the two pliers handles 1 are rotated to separate the rack 6 on the upper part of the pliers head 2 from the clamp ring 8, and then the rivet 4 is slid along the straight slot 5 of one of the pliers heads 2 until the clamping distance between the pliers heads 2 can be adapted to the nut. At this time, the two pliers handles 1 are rotated in the opposite direction so that the clamp ring 8 can slide into the gap between the two racks 6, and the hinged fixing operation between the pliers heads 2 is realized, so that the rivet 4 can no longer reciprocate along the straight slot 5, and then effective abutment is formed between the pliers teeth 7 on the upper part of the pliers head 2 and the side wall of the nut, and then nuts of different sizes can be clamped and driven.
[0018] In general, terms should be understood, at least in part, by the context in which they are used. For example, the term "one or more" as used herein may be used to describe any feature, structure, or characteristic in a singular sense, or may be used to describe a combination of features, structures, or characteristics in a plural sense, depending, at least in part, on the context. Similarly, terms such as "a," "an," or "the" may also be understood to convey singular usage or to convey plural usage, depending, at least in part, on the context.
[0019] It should be easily understood that “on,” “above,” and “over” in the present disclosure should be interpreted in the broadest manner, so that “on” not only means “directly on something,” but also includes the meaning of “on something” with intervening features or layers therebetween, and “above” or “over” not only includes the meaning of “above” or “over,” but also may include the meaning of “above” or “over something” with no intervening features or layers therebetween (i.e., directly on something).
[0020] In addition, spatially relative terms, such as "below," "below," "beneath," "above," "above," etc., may be used herein for ease of description to describe the relationship of one element or feature relative to other elements or features as shown in the figures.

The device may have other orientations (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein may likewise be interpreted accordingly.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
