Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, "and / or" or "and / or" appearing throughout the text means that the three parallel schemes are included, taking "A and / or B" as an example, including A scheme, or B scheme, or A and B scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skill in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0036] The knife switch plays a vital role in the power system, especially in the application of high-voltage electrical cabinet. By manually operating the opening and closing of the knife switch, the on-off of the circuit can be accurately controlled. During the maintenance or repair stage of the high-voltage equipment, the knife switch plays the role of a safety guardian. When necessary maintenance work needs to be carried out on the high-voltage equipment, the ground knife switch is closed by operating the handle. This step is crucial because it can reliably ground the high-voltage equipment, making it at zero potential, thereby effectively preventing accidental electric shock accidents caused by residual voltage of the high-voltage equipment, and providing a safe working environment for maintenance personnel.

[0037] However, according to the applicant's observation and research, it is found that Figure 1 , the conventional operating handle 400 for the opening and closing operation of the knife switch 300 is often designed as a "Z" shape to facilitate the staff to hold. When this setting is adopted, on the one hand, the conventional operating handle 400 occupies a relatively large space when rotating, and if the closing needs to be completed, the conventional operating handle 400 needs to rotate a large arc. If the space around the electrical cabinet 200 is insufficient, the conventional operating handle 400 may collide with the wall or other equipment during the rotation process, and the opening or closing cannot be smoothly completed. On the other hand, the volume and mass of the conventional operating handle 400 are relatively large, and the staff has to make a large amplitude action when using it. When the opening or closing process is not smooth, the conventional operating handle 400 needs to be pulled out and adjusted multiple times, which not only increases the difficulty of operation, but also reduces the work efficiency.

[0038] In view of this, the utility model provides an electrical operating handle to solve the above technical problems.

[0039] Please refer to Figures 2 to 4 In an embodiment of the utility model, the electrical operating handle 100 includes an operating rod 1, a ratchet wrench assembly 2, a sleeve (not shown in the figure) and a rotating rod 3. The ratchet wrench assembly 2 is installed at one end of the operating rod 1. The ratchet wrench assembly 2 includes a gear mechanism and a square head 21. The gear mechanism includes a ratchet wheel and a pawl, the pawl can engage or disengage with the ratchet wheel, and the square head 21 is installed on the ratchet wheel and rotates synchronously with the ratchet wheel. The sleeve includes a tool end and a connecting end, and the connecting end is installed at one end of the square head 21 away from the ratchet wheel. The rotating rod 3 includes an installation end 311 and an operating end 321. The installation end 311 is installed on the tool end, and the operating end 321 is used for inserting into the driver of the ground knife switch 300 and driving the driver to rotate.

[0040] Specifically, the ratchet wrench assembly 2 comprises a ratchet head, which is the part of the conventional ratchet wrench except the handle. The ratchet head is the core component of the ratchet wrench, which comprises a gear mechanism and a square head 21 for connection with an external nut or sleeve. The gear assembly mainly comprises a ratchet and a pawl, which engages with the ratchet in a specific direction, thereby allowing the ratchet head to rotate freely in one direction and be locked in the other direction. At the same time, the ratchet head also comprises a direction switching switch for adjusting the engagement direction of the pawl and the ratchet, and switching the rotation direction of the ratchet head. The ratchet head has the characteristic of one-way rotation, i.e. the pawl engages with the ratchet in one direction, so that the ratchet head can only rotate in one direction, while being locked in the other direction. This one-way rotation characteristic enables the user to swing the handle back and forth in a narrow space for work without frequent repositioning. The ratchet head is installed on the operating rod 1, so that the operating rod 1 serves as a handle for conveniently rotating the ratchet head, for the convenience of the worker holding. In this embodiment, the operating rod 1 is detachably connected with the ratchet head through a threaded structure, so as to replace the operating rod 1 of different lengths, thereby adapting to the torque required for rotating the knife switch 300 of different models. In this embodiment, the sleeve is used to connect the rotating rod 3 with the square head 21. According to different models of the knife switch 300, there are various models of the rotating rod 3. In order to make the square head 21 of one model adapt to various models of the rotating rod 3, the sleeve is arranged between the square head 21 and the rotating rod 3. The connecting end of the sleeve is adapted to the model of the square head 21, and by replacing the sleeve of different models, the tool end of the sleeve is adapted to various models of the rotating rod 3. In this embodiment, the operating rod 1 drives the ratchet wrench assembly 2 to rotate, the square head 21 drives the sleeve to rotate in one direction, so that the sleeve drives the rotating rod 3 to rotate in one direction. The operating end 321 of the rotating rod 3 is inserted into the driver of the knife switch 300, and the rotation of the rotating rod 3 drives the internal structure of the driver to change, thereby realizing the operation of opening and closing the knife switch 300.

[0041] The technical scheme provided in this embodiment combines the ratchet wrench assembly 2, i.e. the ratchet head, with the operating rod 1, and combines the ratchet head with the rotating rod 3 through the sleeve, so that the square head 21 can drive the rotating rod 3 to rotate in one direction. Due to the characteristics of the ratchet head, the square head 21 can be rotated within a limited angle range without completely reversing the wrist, thereby effectively reducing the movement amplitude of the worker when opening and closing the knife switch 300. Even in a small space, by repeatedly rotating the operating rod 1, i.e. the square head 21 can be rotated in the clockwise or counterclockwise direction for multiple times, so that the rotating rod 3 can be rotated in the clockwise or counterclockwise direction for multiple times, and finally the opening and closing operation can be completed in a small space.

[0042] More specifically, in an embodiment of the present application, the connecting end of the sleeve is provided with a first groove, and the square head 21 is inserted into the first groove to enable the sleeve and the square head 21 to rotate synchronously; the tool end of the sleeve is provided with a second groove, and the mounting end 311 of the rotating rod 3 is inserted into the second groove to enable the sleeve and the rotating rod 3 to rotate synchronously. The inner wall of the first groove is enclosed to form a shape identical to that of the square head 21 extending into the interior of the first groove, and the sizes of the two are matched to enable the square head 21 to stably drive the sleeve to rotate. Similarly, the inner wall of the second groove is enclosed to form a shape identical to that of the rotating rod 3 extending into the interior of the second groove, and the size of the second groove is matched with the gear of the rotating rod 3 extending into the interior of the second groove to enable the sleeve to stably drive the rotating rod 3 to rotate.

[0043] In an embodiment of the present application, the rotating rod 3 comprises a mounting cylinder 31 and a switch sub-rod 32, the switch sub-rod 32 is detachably connected with the mounting cylinder 31, the operating end 321 is arranged at one end of the switch sub-rod 32 away from the mounting cylinder 31, and the mounting end 311 is arranged at one end of the mounting cylinder 31 away from the operating end 321. Please refer to Figure 4 , the switch sub-rod 32 and the mounting cylinder 31 are connected through threads or magnetic attraction. The switch sub-rod 32 and the mounting cylinder 31 are one-to-one corresponding, each switch sub-rod 32 corresponds to one mounting cylinder 31, by setting the switch sub-rod 32 and the mounting cylinder 31 as detachable connection, on the one hand, when one of the switch sub-rod 32 and the mounting cylinder 31 is damaged, only the damaged part needs to be re-customized, without replacing the whole rotating rod 3, thereby reducing the maintenance cost; on the other hand, the size of the mounting end 311 of the mounting cylinder 31 is larger than that of the switch sub-rod 32, so that the mounting end 311 is adapted to the tool end of the sleeve, and increasing the size of the mounting end 311 is conducive to the accurate positioning connection of the sleeve and the mounting cylinder 31.

[0044] In an embodiment of the present application, the operating rod 1 is provided with a holding part 11 at one end away from the wrench assembly, and the holding part 11 is sleeved with an anti-skid sleeve 12. The design of the anti-skid sleeve 12 cooperating with the holding part 11 enables the worker to hold the operating rod 1 more conveniently and comfortably when using the electrical operating handle 100, the anti-skid sleeve 12 can increase the friction between the hand and the operating rod 1 to prevent operation failure or accident caused by hand slipping in the use process. At the same time, the anti-skid sleeve 12 is made of a material with certain elasticity, and the manufacturing materials include rubber, modified rubber, nylon and silica gel materials.

[0045] In an embodiment of the present application, please refer to Figure 4In any plane perpendicular to the central axis of the operating rod 1, the projection of the anti-skid sleeve 12 is a circular ring, and the diameter of the projection gradually increases from the two ends of the anti-skid sleeve 12 to the middle part of the anti-skid sleeve 12. The surface of the anti-skid sleeve 12 is provided with anti-skid lines. The anti-skid sleeve 12 has a structure of large in the middle and small at both ends, which is more in line with the palm structure of the human hand. When the user's hand holds the operating rod 1, the fingers and palms can more naturally fit on the surface of the anti-skid sleeve 12, increasing the stability and firmness of holding. Since the middle part of the anti-skid sleeve 12 has a larger diameter, when the user's hand contacts the anti-skid sleeve 12, the contact area increases accordingly. This helps to increase the friction between the hand and the anti-skid sleeve 12, improves the anti-skid performance, and reduces the risk of operation failure caused by the hand slipping off during use. Through the design of the anti-skid lines, the anti-skid performance can be further improved.

[0046] In an embodiment of the present application, the anti-skid sleeve 12 is provided with a hanging hole at the end away from the wrench assembly, and the hanging hole is used for the hook to pass through. The design of the hanging hole allows the user to hang the wrench (with the anti-skid sleeve 12) composed of the operating rod 1 and the ratchet wrench assembly 2 on the hook, rope or any hanging object. This not only saves storage space, but also allows the electrical operating handle 100 to be neatly hung up when not in use, avoiding damage or loss caused by random placement. At the same time, for users who need to carry the electrical operating handle 100 for outdoor work or mobile work frequently, the hanging hole design makes it more convenient to carry.

[0047] Please refer to Figure 5 In an embodiment of the present application, the operating rod 1 includes a connecting sub-rod 13 and a sliding sub-rod 14, and the sliding sub-rod 14 is provided with a sliding cavity 141 along its axial direction, and the connecting sub-rod 13 is slidingly installed in the sliding cavity 141, and the end of the connecting sub-rod 13 away from the sliding cavity 141 is connected with the wrench assembly. Through this arrangement, the operating rod 1 can change its length to change the length of the force arm of the electrical operating handle 100 to adapt to the working conditions in different scenarios.

[0048] In the embodiment of the utility model, the one end of the connecting sub pole 13 that stretches into the sliding sub pole 14 is provided with accommodating cavity 131 and the first through -hole that communicates with accommodating cavity 131, the connecting sub pole 13 still includes spring 132 and the clamping column 133, spring 132 is set in accommodating cavity 131, and the one end of spring 132 is in abutment with the inner wall of accommodating cavity 131, and the other end of spring 132 is set towards the first through -hole, and the clamping column 133 is threaded in the first through -hole, and the one end of the clamping column 133 that is set in accommodating cavity 131 is connected with the one end of spring 132 towards the first through -hole, and the clamping column 133 can slide in the first through -hole;The sidewall of sliding sub pole 14 is provided with multiple second through -holes 142 that are arranged along the axial direction of sliding sub pole 14, and the second through -hole 142 communicates with sliding cavity 141, and the one end of clamping column 133 away from spring 132 sequentially passes through the first through -hole and one of second through -holes 142 to fix the length that the connecting sub pole 13 stretches out of sliding sub pole 14.By pressing the clamping column 133, the clamping column 133 is disengaged with the second through -hole 142, at this time, the connecting sub pole 13 can slide relative to the sliding sub pole 14, thereby adjusting the length that the connecting sub pole 13 stretches out of the sliding sub pole 14, and when the clamping column 133 moves to the adjacent second through -hole 142, it is automatically popped out, at this time, the length that the connecting sub pole 13 stretches out of the sliding sub pole 14 is fixed, if still need to adjust the length, then repeat the above steps until the sliding sub pole 14 is adjusted to the appropriate position.By the setting of the embodiment, the telescopic process of operating rod 1 is more stable, controllable, and the overall length of operating rod 1 can be adjusted step by step to change the force arm of electrical operating handle 100 step by step.

[0049] In the embodiment of the utility model, the ratchet wrench assembly 2 includes a housing 22, the housing 22 is provided with an installation space inside, the gear mechanism is arranged in the installation space, and the housing 22 and the connecting sub pole are an integral molding piece. By integrally molding the housing 22 and the connecting sub pole, there is no connecting gap between the two, so that the torque can be transmitted more effectively, the stress concentration points generated due to splicing are reduced, and the risk of damage of the components due to stress concentration is reduced. The integral molding piece can be molded at one time by processes such as injection molding, casting or 3D printing, without subsequent assembly and debugging work, thereby significantly improving the production efficiency.

[0050] In the embodiment of the utility model, the operating rod 1, the ratchet wrench assembly 2 and the sleeve are coated with an electroplated layer.
