[0044] The preferred embodiment of the easy-to-operate intelligent electric screwdriver provided by the utility model is as follows: an easy-to-operate intelligent electric screwdriver comprises a housing 11, a driving mechanism 12, a forward and reverse switch mechanism 13 and a starting mechanism 14; wherein the housing 11 comprises a hand-grip section 111 and a control section 112, the hand-grip section 111 is located below the control section 112; the driving mechanism 12 is arranged in the housing 11, and the bottom end of the driving mechanism 12 passes through the bottom end of the housing 11, and the driving mechanism 12 is used to output torque; the forward and reverse switch mechanism 13 is arranged on one side of the control section 112, and the forward and reverse switch mechanism 13 is arranged along the housing 11 Axial sliding, and the forward and reverse switch mechanism 13 is connected to the driving mechanism 12, and the forward and reverse switch mechanism 13 is controlled by the user's thumb 21, so as to control the driving mechanism 12 to output torque in the positive or reverse direction; the starting mechanism 14 is set on the other side of the control section 112, and the starting mechanism 14 is rotatably connected to the shell 11, and the rotating shaft 144 of the starting mechanism 14 is perpendicular to the axial direction of the shell 11, the starting mechanism 14 is opposite to the forward and reverse switch mechanism 13, and the starting mechanism 14 is connected to the driving mechanism 12, and the starting mechanism 14 is controlled by the user's index finger 22, so as to start the driving mechanism 12.

[0045] Among them, the hand-gripping section 111 includes a first end 1111, an intermediate connecting portion 1112 and a second end 1113; the first end 1111 is located at one end of the hand-gripping section 111 close to the control section 112, and the first end 1111 is used to correspond to the index finger 22 of the user for holding; the intermediate connecting portion is located in the middle of the hand-gripping section 111, the cross-sectional width of the intermediate connecting portion 1112 is greater than the cross-sectional width of the first end 1111, and the cross-sectional width from the intermediate connecting portion 1112 to the first end 1111 gradually decreases, and the intermediate connecting portion 1112 is used to correspond to the middle finger 23 and the ring finger 24 of the user for holding; the second end 1113 is located at one end of the hand-gripping section 111 away from the control section 112, the cross-sectional width of the second end 1113 is less than the cross-sectional width of the intermediate connecting portion 1112, the cross-sectional width from the intermediate connecting portion 1112 to the second end 1113 gradually decreases, and the second end 1113 is used to correspond to the little finger 25 of the user for holding.

[0046] The smart electric screwdriver in this embodiment is designed with a forward and reverse switch mechanism 13 and a starting mechanism 14, so that the user can easily control the torque direction and start the electric screwdriver through the thumb 21 and the index finger 22. This structural design greatly simplifies the operation process, allowing the user to quickly adapt to and efficiently use the smart electric screwdriver. The design of the hand grip section 111 fully considers the structure and holding habits of the human hand. The different cross-sectional widths and gradually changing design of the first end 1111, the middle connecting portion 1112 and the second end 1113 enable the index finger 22, the middle finger 23, the ring finger 24 and the little finger 25 to be comfortably supported and held. This design can reduce hand fatigue and improve the user experience.

[0047] The structure of the intelligent electric batch in this embodiment is described in detail as follows:

[0048] Combination Figure 2 In this embodiment, a limiting portion 1121 is provided at one end of the control section 112 close to the grip section 111 , and the cross-sectional width of the limiting portion 1121 close to the first end 1111 gradually decreases. The limiting portion 1121 is used to limit the position of the thumb 21 .

[0049] The design of the limit portion 1121 can effectively limit the position of the thumb 21, so that when the user operates the smart electric screwdriver (especially when operating the start switch 141), the thumb 21 can be naturally placed on the limit portion 1121. This design helps the user to form a correct holding posture and improves the stability and accuracy of the operation. Since the cross-sectional width of the limit portion 1121 gradually decreases, this gradual design can better adapt to the shape of the thumb 21, which can reduce the risk of accidental sliding of the thumb 21 during operation, thereby avoiding possible safety accidents and improving the safety of operation.

[0050] In this embodiment, a mounting groove 113 is provided on the side of the housing 11, and the mounting groove 113 is located at the limiting portion 1121; the intelligent electric screwdriver further includes a colored sealing ring 114, and the colored sealing ring 114 is embedded in the mounting groove 113. The limiting portion 1121 is provided with a colored sealing ring 114, and the color of the colored sealing ring 114 in this embodiment is different from that of the housing 11, which can serve as an operation guide. The user only needs to place the thumb 21 on the limiting portion 1121 to quickly master the correct holding method, thereby reducing the learning cost.

[0051] The starting mechanism 14 and the forward and reverse switch mechanism 13 in this embodiment are described as follows:

[0052] Combination Figure 3 and Figure 4The starting mechanism 14 in this embodiment includes a starting switch 141, a seesaw shaft 142 and a return spring 143; the starting switch 141 is arranged in the housing 11, and the starting switch 141 is connected to the driving mechanism 12; the seesaw shaft 142 is rotatably connected to the housing 11, and the rotation axis 144 of the seesaw shaft 142 is perpendicular to the axial direction of the housing 11, and the top of the seesaw shaft 142 is movably connected to the starting switch 141, and the seesaw shaft 142 is used to trigger the starting switch 141; the return spring 143 is located below the starting switch 141, one end of the return spring 143 is connected to the housing 11, and the other end of the return spring 143 is connected to the seesaw shaft 142, and the return spring 143 drives the seesaw shaft 142 away from the starting switch 141.

[0053] The design of the seesaw shaft 142 allows the user to trigger the start switch 141 and start or stop the drive mechanism 12 by simply pressing. This operation method is intuitive and easy to understand, and is convenient for users to use. Since the seesaw shaft 142 is directly and movably connected to the start switch 141, when the user presses the seesaw shaft 142, the start switch 141 can respond quickly to ensure that the drive mechanism 12 starts or stops in time. The presence of the return spring 143 ensures that the seesaw shaft 142 can quickly return to its original position after triggering the start switch 141, preparing for the next operation, avoiding safety risks caused by the user forgetting to release or misoperation.

[0054] The seesaw shaft 142 includes a first fixing portion 1421, a second fixing portion 1422, and a third fixing portion 1423. The first fixing portion 1421 is located at the top of the seesaw shaft 142, and the first fixing portion 1421 is movably connected to the start switch 141, ensuring that the user can trigger the start switch 141 by pressing the seesaw shaft 142. The second fixing portion 1422 is located in the middle of the seesaw shaft 142, and the top of the second fixing portion 1422 is rotatably connected to the housing 11 through the rotating shaft 144, and the bottom of the second fixing portion 1422 is connected to the reset spring 143. The second fixing portion 1422, as the main body of the seesaw shaft 142, is rotatably connected to the housing 11 through the rotating shaft 144. When the seesaw shaft 142 is pressed, the reset spring 143 can drive the seesaw shaft 142 back to the initial position, and the seesaw shaft 142 can rotate stably and smoothly, thereby ensuring the triggering of the start switch 141.

[0055] The third fixing portion 1423 is located at the bottom of the rocker shaft 142, and the bottom end of the third fixing portion 1423 extends downward, and the distance between the end of the third fixing portion 1423 away from the second fixing portion 1422 and the housing 11 gradually increases. The design of the third fixing portion 1423 makes the distance between the end of the bottom of the rocker shaft 142 away from the second fixing portion 1422 and the housing 11 gradually increase. This design conforms to the principle of ergonomics, making the user's fingers more comfortable when pressing the rocker shaft 142, reducing hand fatigue.

[0056] In this embodiment, a pressing arc surface 14231 is provided on the side of the third fixing portion 1423 away from the housing 11. The pressing arc surface 14231 corresponds to the position pressed by the index finger 22, and the opening of the pressing arc surface 14231 faces the side away from the housing 11. The pressing arc surface 14231 matches the natural curvature of the index finger 22, so that the index finger 22 of the user can fit more comfortably on the arc surface when operating the smart electric screwdriver. Since the index finger 22 fits tightly against the pressing arc surface 14231, the user can obtain better stability during operation, which helps to reduce false triggering or operating errors caused by improper operation, and improve work quality and safety.

[0057] In this embodiment, a spring positioning groove 14221 is further provided on the side of the second fixing portion 1422 close to the housing 11 , and one end of the return spring 143 is embedded in the spring positioning groove 14221 to prevent the return spring 143 from falling off, thereby improving the stability of the connection between the rocker shaft 142 and the return spring 143 .

[0058] In this embodiment, the forward and reverse switch mechanism 13 includes a forward and reverse switch 131 and a sliding key 132. The forward and reverse switch 131 is arranged in the housing 11 and connected to the driving mechanism 12. The sliding key 132 is slidably connected to the housing 11, and the position of the sliding key 132 corresponds to the position of the second fixing portion 1422. The sliding key 132 is used to trigger the forward and reverse switch 131. The sliding key 132 facilitates the user to control the forward and reverse switch 131 through a simple sliding action, thereby realizing the forward and reverse torque output of the driving mechanism 12. By arranging the forward and reverse switch 131 inside the housing 11 and slidably connecting with the sliding key 132, external space can be saved. The position of the sliding key 132 corresponds to the position of the second fixing portion 1422 on the rocker shaft 142. When the index finger 22 is attached to the third fixing portion 1423 of the rocker shaft 142, the thumb 21 in the vertical state is in the sliding range of the sliding key 132. This structural design conforms to the ergonomic principle, so that the user can operate the smart electric screwdriver more smoothly.

[0059] Combination Figure 3 In this embodiment, the hand grip section 111 is provided with first anti-slip stripes 1114, and the first anti-slip stripes 1114 are provided in a plurality of groups, and the plurality of groups of first anti-slip stripes 1114 are arranged around the circumference of the housing 11. The design of the first anti-slip stripes 1114 increases the friction between the hand grip section 111 and the palm, so that the user can hold the smart electric screwdriver more stably when using it, reducing the risk of slipping, thereby improving the safety and accuracy of the operation.

[0060] Combination Figure 1 and Figure 3A limiting groove 1122 is provided on the side of the control section 112 away from the forward and reverse switch mechanism 13, and the limiting groove 1122 is used to limit the position of the index finger 22. The limiting groove 1122 allows the end of the index finger 22 close to the palm of the user to be placed in the limiting groove 1122 during operation, thereby enhancing the support function of the index finger 22, making the position of the index finger 22 of the user more stable, and being able to more accurately control the start mechanism 14, thereby improving the grip stability of the entire hand.

[0061] Furthermore, in this embodiment, the side of the sliding key 132 away from the starting mechanism 14 is an arched surface, and the arched surface is provided with a second anti-slip stripe 1321, so that it does not slip when it is moved up and down, thereby improving the practicality of the structure. The sliding key 132 is provided with a second anti-slip stripe 1321, and the second anti-slip stripe 1321 is located on the side of the sliding key 132 away from the starting mechanism 14. The design of the second anti-slip stripe 1321 increases the friction between the user's finger and the sliding key 132, so that the user can control the sliding of the sliding key 132 more stably when operating it, reducing the risk of slipping or accidental movement, and improving the accuracy and stability of the operation.

[0062] The working principle of this utility model:

[0063] The easy-to-operate intelligent electric screwdriver mainly includes a housing 11, a driving mechanism 12, a forward and reverse switch mechanism 13 and a starting mechanism 14.

[0064] 1. The housing 11 is composed of a grip section 111 and a control section 112. The grip section 111 is designed to be held by a human hand, and the control section 112 integrates operating controls.

[0065] The middle connecting portion 1112 of the grip section 111 has a larger cross section than the first end 1111 and the second end 1113. The grip section 111 is a raised arc structure that matches the concave shape of the palm. The grip section 111 of the whole electric screwdriver indicates the position of holding. The design of the grip section 111 takes into account the principle of ergonomics. Different cross-sectional widths are designed to adapt to the grip of different fingers. At the same time, the first anti-slip stripe 1114 also enhances the stability of the grip, so that you will not feel tired even after long-term use.

[0066] 2. When holding the device, the third fixing portion 1423 of the starter rocker shaft 142 can be started and stopped when the index finger 22 is extended and retracted. In this lying position, the thumb 21 is erected, and the sliding key 132 can be slid up and down, which is convenient for the hand-held control of the smart electric screwdriver. The first anti-slip stripe 1114 on the hand grip section 111 enhances the grip stability and prevents hand slippage; the limiting groove 1122 on the side of the control section 112 away from the forward and reverse switch mechanism 13 provides a stable placement position for the index finger 22, which is convenient for operation.

[0067] 3. The driving mechanism 12 outputs torque to complete operations such as tightening or loosening the screw.

[0068] The forward and reverse switch mechanism 13 is operated by sliding the slide key 132 with the user's thumb 21, thereby controlling the torque direction output by the drive mechanism 12 to achieve forward or reverse rotation. The forward and reverse switch mechanism 13 adopts an up-and-down sliding type. When the slide key 132 is pushed upward, the electric screwdriver is reversed and the screw is loosened upward; when the slide key 132 is pushed downward, the electric screwdriver is forward rotated and the screw is tightened downward.

[0069] The start mechanism 14 is operated by the user's index finger 22 to start the drive mechanism 12. The start mechanism 14 includes a start switch 141, a seesaw shaft 142, and a return spring 143. When the user presses the third fixing portion 1423 of the seesaw shaft 142 with the index finger 22, the seesaw shaft 142 rotates around its rotation axis 144, thereby triggering the start switch 141 and starting the drive mechanism 12. The return spring 143 ensures that after the index finger 22 is released, the seesaw shaft 142 can automatically return to its original position, and the start switch 141 stops.

[0070] In addition, the operation is convenient: the design of the smart electric screwdriver makes the operation very simple and intuitive. The user only needs to slide the forward and reverse switch mechanism 13 with the thumb 21 to control the torque direction, and press the start mechanism 14 with the index finger 22 to start the drive mechanism 12. This design reduces the operation steps and improves work efficiency.

[0071] This completes the working process of the easy-to-operate intelligent electric screwdriver of the preferred embodiment.

[0072] The electrical connection between the start switch 141 and the forward and reverse switch 131 and the drive mechanism 12, as well as the corresponding driving principle, controls the operation of the drive mechanism 12 through the circuit to realize the start of the tool and the switching of the rotation direction, which belongs to the prior art in the field of intelligent electric screwdrivers and is a relatively conventional design in the industry. The invention of this application does not involve these basic connection structures and driving mechanisms, but the structure of the intelligent electric screwdriver housing 11 is ergonomic. This design not only takes into account the natural gripping posture of the user's hand, but also optimizes the stability and comfort of the grip.

[0073] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
