In order to achieve the above-mentioned purpose, the application provides a spanner, including vertical holding rod the upper end of vertical holding rod is connected with even board, lower extreme is connected with the adjustable spanner, just adjustable spanner and even board all set up along the horizontal direction, the adjustable spanner is used for using with corresponding nut cooperation be equipped with the through-hole along the vertical direction on the even board, the loose axle passes the through-hole, and relative the through-hole can reciprocate and rotate the top of loose axle is equipped with horizontal holding rod along the horizontal direction be connected with the socket spanner, works as when loose axle and socket spanner are in connected state, the socket spanner is in the below of even board, the socket spanner is used for using with corresponding nut cooperation, the external diameter of socket spanner is greater than the diameter of through-hole under the condition that loose axle and socket spanner are assembled together, when the loose axle is moved up and down can not break away from even the board.

In some embodiments, the vertical grip is sleeved with a non-slip insulating sleeve, and the horizontal grip is sleeved with a non-slip insulating sleeve.

In some embodiments, the movable shaft is detachably connected with the socket wrench by magnetic attraction.

In some embodiments, the inner wall of the through hole is smooth.

The beneficial effect of this scheme of this application lies in above-mentioned spanner, and it can be controlled by single, loosens or fastening operation to the top nut when fixing low pressure side copper bar below nut.

Detailed Description

The following describes the embodiments of the present application further with reference to the accompanying drawings.

In the description of the present application, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate an orientation or a positional relationship based on that shown in the drawings, merely for convenience of description and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application.

As shown in fig. 1, the spanner that this application relates to includes vertical holding rod 1, the cover has anti-skidding insulating cover on the vertical holding rod 1 the upper end of vertical holding rod 1 is connected with even board 3, lower extreme is connected with adjustable spanner 2, just adjustable spanner 2 and even board 3 all set up along the horizontal direction, adjustable spanner 2 is used for using with corresponding nut cooperation, for example with the below nut 10 cooperation of copper bar be used be equipped with through-hole 4 along the vertical direction (being the upper and lower direction) on even board 3 loose axle 5 pass through-hole 4 and relative through-hole 4 can reciprocate and rotate the top of loose axle 5 is equipped with horizontal holding rod 6 along the horizontal direction, the cover has anti-skidding insulating cover 7 on the horizontal holding rod 6, the bottom detachable of loose axle 5 is connected with socket spanner 8, for example axle 5 adopts the mode of magnetic attraction to dismantle with socket spanner 8, when being in connected state, socket spanner 8 is in the below of even board 3 is used for using with corresponding socket 8, the socket 8 is used for using down the cooperation of socket spanner 5, can not be in the diameter by the diameter is in the big way of socket spanner 8 when the loose axle 5 is equipped with the socket 8.

In this embodiment, the inner wall of the through-hole 4 is polished to make the inner wall smooth, so that the friction force with the inner wall of the through-hole 4 when the movable shaft 5 moves in the up-down direction can be reduced.

In a specific use process, as shown in fig. 2, a worker holds the vertical holding rod 1 with one hand, fixes the lower nut 10 of the copper bar 9 by using the loose end wrench 2, then moves the movable shaft 5 by manipulating the horizontal holding rod 6 with the other hand, aligns the socket wrench 8 with the upper nut 11 of the copper bar 9, and then rotates the horizontal holding rod 6 to complete loosening or fastening operation on the upper nut 11.

The spanner that this application relates to can be controlled by single, loosens or fastening operation is carried out to the top nut when fixing low pressure side copper bar below nut, convenient operation makes the process that the transformer low pressure side copper bar traded and adorns current transformer become easy to operate.

The foregoing is only a preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art, within the scope of the present application, should make equivalent substitutions or modifications according to the technical solution and the concept of the present application, and should be covered by the scope of the present application.
