Fig. 1 shows a schematic structural diagram of a torque transfer tool according to an embodiment of the present invention.

As shown in fig. 1-2, an embodiment of the present invention provides a torque transfer tool, wherein the tool includes a C-shaped torque transfer connecting rod 21, a positioning transfer screw 22 and a screw connector 3, an adapter is provided at an upper end of the C-shaped torque transfer connecting rod 21, the adapter includes a first falcon opening 4 and a second falcon opening 5, the C-shaped torque transfer connecting rod 21 is connected to a standard torque wrench 1 through the first falcon opening 4, the C-shaped torque transfer connecting rod 21 is connected to the positioning transfer screw 22 through the second falcon opening 5, and the screw connector 3 is disposed at a lower end of the C-shaped torque transfer connecting rod 21 and is used for being connected to a screw.

Wherein, through falcon mouth connected mode, can make the connection more nimble. When torque does not need to be applied, the standard torque wrench is taken down from the first falcon opening; similarly, the positioning adapter screw can also be detached from the second falcon opening.

Through above-mentioned technical scheme, can provide a switching frock for the moment of fastener is applyed in narrow and small installation space, be convenient for with the butt joint of traditional moment spanner, make the application of screwing up moment nimble more convenient, solved among the prior art common moment spanner switching frock and be difficult to the problem that the direction was applyed to the conversion moment.

According to one embodiment of the utility model, the C-shaped torque transfer link 21 is formed by machining in one machine.

According to an embodiment of the present invention, the screw connector 3 is disposed to protrude from a surface of a lower end of the C-shaped torque transfer link 21, and the screw connector 3 is coupled to a head of a screw in a fitting manner.

For example, the screw connector may be inserted into the head of a screw to make a connection.

According to one embodiment of the utility model, the screw connection head 3 is a hexagonal prism.

In the case that the screw connector is a hexagonal prism, the screw connector can be matched and connected with the hexagon socket head cap screw, namely, the hexagonal prism is inserted into the hexagon socket head cap head of the hexagon socket head cap screw.

It will be appreciated by persons skilled in the art that the above description is illustrative only and not intended to limit the utility model.

According to an embodiment of the present invention, the central axis of the screw connector 3 is coaxial with the central axis of the adapter.

The process of applying torque to the transfer tool according to the present invention will be described with reference to fig. 2.

In this example, the screw 8 is a socket head cap screw, which is merely exemplary and not intended to limit the present invention.

When the switching tool is used for connecting a first connected piece 6 and a second connected piece 7 (wherein the first connected piece 6 is provided with a common hole, and the second connected piece 7 is provided with a threaded hole), firstly, an inner hexagonal screw is screwed into the first connected piece 6 and the second connected piece 7 (not screwed), a positioning switching screw 22 is screwed into the second connected piece 7 (not screwed), then, the positioning switching screw 22 is adjusted to be matched with a square tenon groove (a second tenon opening 5) on the side surface of a moment switching connecting rod 21 to form connection, meanwhile, a screw connector 3 at one end of the moment switching connecting rod 21 is inserted into a nail head of the inner hexagonal screw, and the connection of the moment switching tool, the screw and the connected pieces is completed at the moment. Subsequently with standard torque wrench 1 and moment switching connecting rod 21 upward rotate the first falcon mouth 4 of joint and be connected, can carry out moment and apply. When the torque switching device is used, the positioning switching screw rod 22 is screwed into a threaded hole of the second connected piece 7 to play a role in fastening axial positioning, the rotation direction of the torque wrench after the reversing is ensured to be coaxial with the screw, a common right-handed thread is taken as an example, the standard torque wrench transmits torque (Z direction) to the torque switching connecting rod 21 through the first rabbet 4, and then the torque is transmitted to the screw through the screw connector 3. When the torque tool is not used, the torque tool needs to be screwed clockwise from the top surface of the torque wrench, and when the torque tool is used, the torque tool needs to be screwed anticlockwise, namely the torque tool can turn the screwing direction of a standard torque wrench by 180 degrees to apply torque, so that the problem that the torque is inconvenient to apply due to the fact that the original position space is narrow is solved.

Under the same working condition, the torque is directly applied by using a standard torque wrench without using the torque switching tool, and because the adapter of the standard torque wrench 1 is longer, after the socket head cap screw is screwed into the first connected piece and the second connected piece, because the space between the frame bodies of the first connected piece and the second connected piece is narrow, the head of the socket head cap screw 2 cannot be inserted into the standard torque wrench 1, and the interference occurs between the head of the socket head cap screw 1 and the frame body of the first connected piece.

Therefore, the torque switching tool solves the problem that the torque application direction is difficult to switch by a common torque wrench switching tool in the prior art.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … … surface," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of the present invention should not be construed as being limited.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
