[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 5 A handheld lithium-ion wrench with a shock-absorbing structure comprises a wrench body 1, wherein the wrench is powered by lithium battery to realize overall operation, wherein the lithium-ion wrench generally drives a sleeve 5 to rotate through a motor to realize the rotation of a bolt.

[0021] The body 1 is provided with a connecting member 2, which is used to cooperate with the sleeve 5. By replacing different sleeves 5, different bolts can be operated. The connecting member 2 includes a transmission part 3 and a mounting part 4, wherein the mounting part 4 has a circular cross section, which is intended to ensure that the sleeve 5 cannot rotate when the sleeve 5 is embedded. The transmission part 3 has a polygonal cross section. In this embodiment, the cross section of the transmission part 3 is a hexagon. When the sleeve 5 is embedded in the transmission part 3, the connecting member drives the sleeve 5 to rotate to ensure effective power transmission.

[0022] A movable control plate 6 is provided in the connector 2, and the control plate 6 is connected to the inside of the body 1 by a first spring 7. When the first spring 7 is in a stationary state, the control plate 6 is in the mounting portion 4 and cannot drive the sleeve 5 to move. Therefore, when it is required to work, the sleeve 5 needs to be located in the transmission portion 3, that is, during operation, force needs to be applied to overcome the spring resistance, and the sleeve 5 moves to the transmission portion 3 to complete the work. In this way, during the operation, it is ensured that the bolt completely enters the sleeve 5, ensuring safety during rotation.

[0023] Furthermore, a marking assembly is also provided in the body 1. The marking assembly includes a housing 8 and a marking member 9, the marking member 9 slides in the housing 8, and the second spring 10 is located between the housing 8 and the marking member 9, while fixing the housing 8 to one side of the control board 6. A slide bar 11 is provided at the bottom of the marking member 9, the slide bar 11 is slidably provided in the housing 8, a limit block 12 is provided on the slide bar 11, and the limit block 12 protrudes from the housing 8, that is, the limit block 12 will resist the housing 8 to restrain the movement of the marking member 9.

[0024] Furthermore, in order to realize automatic marking of the marking member 9 after completing the work, an electromagnet is arranged on the control panel 6, and a magnet is arranged on the limit block 12, and the two groups of magnetic poles are opposite to each other. Therefore, when the electromagnet is energized, the limit block 12 drives the mark to move toward the side of the bolt and overcomes the second spring 10 in the process.

[0025] Since the mark needs to be reset, the control electromagnet needs to be disconnected in time. Therefore, the power supply of the electromagnet is a battery, and a connection point is set on the body 1. When the control board 6 moves to abut the release point on the body 1, the battery is powered off and charged. When the sleeve 5 leaves the bolt, the control board 6 will be separated from the contact point 13, the electromagnet will be energized, consuming the power of the battery, and the marking member 9 moves toward the bolt and marks it.

[0026] Furthermore, the marking member 9 can be a marking pen, and the shape of the mark can be special and have a shape. When it is found that the shape of the mark of the screw and the bolt is deformed, it can be known that the bolt has been rotated, thereby strengthening safety management and facilitating tracking and verification.

[0027] Finally, the body 1 is provided with a hand-held portion 14, which is covered with shock-absorbing rubber to enhance the grip, reduce fatigue caused by long-term operation, and improve overall comfort, thereby optimizing the use experience of hand-held tools.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
