[0045] 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.

[0046] Please refer to Figures 1 to 6 As shown, an embodiment of the present invention provides an electric installation tool, which at least includes a tool body 100, a drive sleeve 200, a stop wrench 300 and an electric drive mechanism. The drive sleeve 200 is rotatably arranged on the tool body 100, and the drive sleeve 200 is used to disassemble and assemble the nut 20; the stop wrench 300 is movably inserted in the drive sleeve 200, the stop wrench 300 can move along the axial direction of the drive sleeve 200 and be limited circumferentially with the tool body 100, and the stop wrench 300 is used to fix the bolt 10; the electric drive mechanism is arranged on the tool body 100, the electric drive mechanism can be transmission-connected to the drive sleeve 200, and the electric drive mechanism is used to drive the drive sleeve 200 to rotate.

[0047] In general, when the electric installation tool is used, the drive sleeve 200, the stop wrench 300 and the electric drive mechanism are arranged on the tool body 100, and the drive sleeve 200 can be driven to rotate by the electric drive mechanism, so that no external air source power is required, which helps to improve the integration of the electric installation tool. In addition, since the electric installation tool does not need to be connected to the air source pipeline, the electric installation tool is also more portable, so that it can be better used in complex places or small spaces, and has better flexibility of use.

[0048] Specifically, Figure 5 and Figure 6 In the embodiment shown, when disassembling and assembling the high-locking bolt 10 and the matching nut 20, the drive sleeve 200 is sleeved on the periphery of the nut 20, and the stop wrench 300 is inserted into the tail wrench groove of the bolt 10, and then the drive sleeve 200 is driven to rotate by the electric drive mechanism, and then the nut 20 is rotated by the drive sleeve 200 to realize the disassembly and assembly operation.

[0049] The stop wrench 300 and the tool body 100 are circumferentially limited, and the stop wrench 300 will not rotate with the drive sleeve 200, thereby preventing the bolt 10 from rotating, and only the nut 20 can rotate during the disassembly process. In addition, the stop wrench 300 can move along the axial direction of the drive sleeve 200, and then when the relative position of the nut 20 and the bolt 10 changes, the stop wrench 300 can be dynamically adjusted along the axial direction of the drive sleeve 200, so that the stop wrench 300 will not interfere with the bolt 10, and has a better use effect.

[0050] In the embodiment of the present invention, the designer can adjust the specific shape and structure of the driving sleeve 200 according to the use requirements, and no specific limitation is made here.

[0051] Preferably, an adjustment through hole is formed on the drive sleeve 200, and a nut slot is provided at one end of the adjustment through hole away from the tool body 100, and the cross-section of the nut slot matches the shape of the nut 20 to be disassembled and assembled, so that the drive sleeve 200 can drive the nut 20 to rotate.

[0052] In an embodiment of the present invention, Figure 2 and Figure 3 In the illustrated embodiment, the electric drive mechanism includes a power unit 400 , a transmission mechanism and an energy storage battery 600 arranged on the tool body 100 , the energy storage battery 600 is electrically connected to the power unit 400 , and the transmission mechanism can transmission-connect the power unit 400 and the drive sleeve 200 .

[0053] By integrating the power unit 400, the transmission mechanism and the energy storage battery 600 on the tool body 100, the energy storage battery 600 can provide a continuous and stable power supply for the power unit 400. In addition, the energy storage battery 600 can move with the electric installation tool, thereby eliminating the need for external gas power and providing greater flexibility of use.

[0054] Furthermore, the power generated by the power unit 400 can be efficiently transmitted to the drive sleeve 200 through the transmission mechanism, thereby reducing energy loss during the transmission process and improving the transmission efficiency. By arranging the power unit 400 on the tool body 100, the power unit 400 can provide stable power to drive the drive sleeve 200 to rotate, thereby improving the disassembly and assembly efficiency of the high-locking bolt 10 and the matching nut 20.

[0055] The designer can adjust the shape of the tool body 100 according to the use requirements, and no specific limitation is imposed here. Preferably, the tool body 100 is configured in a rod shape.

[0056] The rod-shaped tool body 100 is convenient for sequentially installing various functional components, which helps to improve integration. In addition, the radial dimension of the rod-shaped tool body 100 is small, which is convenient for operators to grasp the tool body 100, so that it can be better used in complex places or narrow spaces, improving operational flexibility.

[0057] In an embodiment of the present invention, Figure 3 In the illustrated embodiment, the power unit 400 includes a motor, the rotating shaft of the motor is arranged along the extension direction of the tool body 100; the transmission mechanism includes a transmission member 510 connected to the rotating shaft of the motor, and a power converter 520 transmission-connected to the transmission member 510, and the power converter 520 is transmission-connected to the drive sleeve 200.

[0058] Preferably, the axis of the drive sleeve 200 is perpendicular to the rotating shaft of the motor. By making the axis of the drive sleeve 200 perpendicular to the rotating shaft of the motor, the overall structure of the electric installation tool is more compact, effectively reducing the size of the electric installation tool, making it easier to carry and operate, and particularly suitable for use in small spaces or complex working conditions.

[0059] Of course, in other feasible embodiments, designers can adjust the angle between the axis of the drive sleeve 200 and the rotating shaft of the motor according to usage requirements, and no specific limitation is made here.

[0060] Furthermore, since the motor and the power converter 520 are respectively installed at different positions of the tool body 100, the rotating shaft of the motor cannot be directly connected to the power converter 520 for transmission. At this time, a transmission member 510 is arranged between the rotating shaft of the motor and the power converter 520, and the transmission member 510 is used to play a transmission role.

[0061] Designers can adjust the specific structure of the transmission member 510 according to the use requirements, and no specific limitation is made here. Preferably, the transmission member 510 is a gear transmission structure, which has efficient power conversion and precise torque transmission, thereby helping to control the rotation angle of the drive sleeve 200.

[0062] In an embodiment of the present invention, Figure 4 In the illustrated embodiment, the power converter 520 includes a first bevel gear 521 connected to the transmission member 510 , and a second bevel gear 522 meshing with the first bevel gear 521 , and the second bevel gear 522 is used to connect to the drive sleeve 200 .

[0063] The first bevel gear 521 and the second bevel gear 522 cooperate with each other to achieve a transmission function, and have efficient power conversion and precise torque transmission, thereby improving the overall performance and reliability of the electric installation tool.

[0064] Furthermore, the bevel gear transmission can realize the transmission of power in different planes, so that the power is converted from the horizontal rotation axis of the motor to the vertical rotation axis of the drive sleeve 200, thereby optimizing the spatial layout. Furthermore, by controlling the matching angle between the first bevel gear 521 and the second bevel gear 522, the transmission direction can also be converted, which has better flexibility of use.

[0065] The designer can adjust the shape of the first bevel gear 521 and the second bevel gear 522 according to the use requirements, and no specific restrictions are imposed here. Specifically, the second bevel gear 522 is provided with a through hole for the stop wrench 320 to pass through.

[0066] Of course, in other feasible embodiments, the rotating shaft of the motor may be directly connected to the first bevel gear 521 , thereby achieving a direct rotation effect, which is not specifically limited herein.

[0067] In an embodiment of the present invention, Figure 1 and Figure 2 In the embodiment shown, an elbow 110 is provided at one end of the tool body 100, and a power converter 520 is arranged in the elbow 110. An adjustment through hole is provided on the elbow 110 for a stop wrench 300 to pass through, and the stop wrench 300 can be movably inserted in the adjustment through hole; the electric installation tool also includes a circumferential limiting structure arranged between the elbow 110 and the stop wrench 300.

[0068] By setting an elbow 110 at one end of the tool body 100, the elbow 110 can accommodate the power converter 520, and the elbow 110 can also protect the power converter 520 to prevent foreign matter from entering the power converter 520 and affecting the normal use of the power converter 520.

[0069] Furthermore, by providing an adjustment hole on the elbow 110, the stop wrench 300 can be freely adjusted along the adjustment hole during use so as to be better inserted into the tail wrench groove of the bolt 10, and the circumferential limiting structure can play a circumferential limiting role on the stop wrench 300, thereby preventing the stop wrench 300 and the bolt 10 from rotating during the disassembly and assembly process.

[0070] Specifically, Figure 5 and Figure 6 In the illustrated embodiment, the circumferential limiting structure includes a guide groove disposed in the adjustment through hole and a guide key disposed on the stop wrench 300, and the guide key is matched and connected with the guide groove.

[0071] By utilizing the guide key in conjunction with the guide groove, a circumferential limiting function can be achieved between the adjustment through hole and the stop wrench 300 to prevent the stop wrench 300 from rotating, so that the stop wrench 300 can better fix the bolt 10 .

[0072] The designer can adjust the specific shape of the guide key on the stop wrench 300 according to the use requirements, and no specific restrictions are made here. For example, the guide key is constructed in any form such as a hexagonal head, a five-flowered groove, a spline, etc., and the guide groove is matched with the guide key.

[0073] The designer can adjust the specific structure of the stop wrench 300 according to the use requirements, and no specific limitation is made here. Preferably, the stop wrench 300 includes a rod body 310 and a stop wrench head 320 arranged at one end of the rod body 310, and the stop wrench head 320 is used to be inserted into the tail end wrench groove of the bolt 10. The stop wrench head 320 is matched with the tail end wrench groove of the bolt 10.

[0074] In an embodiment of the present invention, Figure 1 and Figure 2 In the illustrated embodiment, the electric installation tool further includes a direction regulator 720 disposed on the tool body 100 . The direction regulator 720 is electrically connected to the power unit 400 . The direction regulator 720 is used to control the rotation direction of the power unit 400 .

[0075] The power unit 400 can be rotated in both positive and negative directions by the direction regulator 720, so as to realize disassembly or installation operations, which greatly expands the application scope of the electric installation tool and improves the flexibility of the use of the electric installation tool. The user can select the appropriate rotation direction according to actual needs, and no specific restrictions are made here.

[0076] In a feasible embodiment, the direction regulator 720 can change the positive and negative poles of the connected power source by rotating, thereby controlling the power unit 400 to realize forward and reverse rotation.

[0077] The designer can adjust the specific model of the direction regulator 720 according to the use requirements, and no specific limitation is made here. Preferably, the direction regulator 720 includes a direction ring arranged on the tool body 100, and the direction ring has two gears. The direction ring can be switched between the two gears by rotating, thereby controlling the power unit 400 to rotate forward and reverse.

[0078] In an embodiment of the present invention, the electric installation tool further includes a sensor module 730 , and the sensor module 730 is used to obtain angle data and / or torque data of the power unit 400 .

[0079] Preferably, Figure 3 In the illustrated embodiment, the sensing module 730 includes a torque sensor 731 and an angle encoder 732 . The torque sensor 731 is used to obtain torque data of the power unit 400 , and the angle encoder 732 is used to obtain angle data of the power unit 400 .

[0080] The torque sensor 731 can obtain the torque data of the power unit 400 in real time, ensuring accurate monitoring of the working state of the electric installation tool, making the output torque of the power unit 400 controllable, so that the installation torque of the high-locking bolt 10 and the matching nut 20 can be more accurately controlled, thereby improving the installation accuracy. The angle encoder 732 can obtain the angle data of the power unit 400 in real time, providing detailed rotation angle information, so that the user can accurately control the rotation angle of the electric installation tool, improving the accuracy of the operation.

[0081] Furthermore, through the torque and angle data provided by the torque sensor 731 and the angle encoder 732, the user can optimize the operation process and reduce unnecessary repeated operations, thereby improving the overall work efficiency.

[0082] In an embodiment of the present invention, Figure 3 In the embodiment shown, the electric installation tool also includes a control module 700, which is electrically connected to the power unit 400, the sensor module 730 and the direction regulator 720. The control module 700 is provided with a control switch 710, which is used to start or shut down the electric installation tool.

[0083] By electrically connecting the control module 700 to the power unit 400, the sensor module 730 and the direction regulator 720, the control module 700 can monitor and adjust the working status of each component in real time to ensure efficient, safe and stable operation of the electric installation tool. The setting of the control switch 710 simplifies the user's operation, makes the start and stop of the tool more convenient, and improves the user experience.

[0084] Designers may adjust the specific structure of the control module 700 according to usage requirements. For example, the control module 700 includes a chip board disposed in the tool body 100, which is not specifically limited here.

[0085] Furthermore, the electric installation tool also includes a memory card module 760 , which is disposed in the tool body 100 and is electrically connected to the control module 700 .
