The direction of second knife group 300 rotating out of the second knife mouth 107 is opposite to the direction of first knife group 200 rotating out of the first knife mouth 106. Specifically, first knife group 200 rotates out of the accommodation cavity 105 along the clockwise direction, and second knife group 300 rotates out of the accommodation cavity 105 along the counterclockwise direction, and this layout makes the compact structure of cutting tool, and the operation is convenient.

Rotation stop body 402 includes rotation stop main body 404 and two rotation stop pins 405 suitable for cooperating locking groove 403. First pivot 103 includes first pivot cavity 108 and guide groove 109, and a limiting partition plate 110 is arranged in first pivot cavity 108, and the limiting partition plate 110 is perpendicular to the first pivot 103, and the limiting partition plate 110 divides first pivot cavity 108 into unlocking cavity 111 and locking cavity 112, and the rotation stop main body 404 is arranged in the locking cavity 112, and the locking spring is abutted between the rotation stop main body 404 and the locking cavity 112, and the rotation stop pin 405 extends through the guide groove 109. When locking groove 403 rotates to align with guide groove 109, first knife group 200 is in the storage state or the unfolded state, and the locking spring is suitable for driving and keeping the rotation stop pin 405 to extend into the locking groove 403, so as to limit the rotation of first knife group 200 relative to casing 100 and realize locking, and unlocking button 401 is suitable for driving rotation stop body 402 to exit locking groove 403 to release the locking.That is, the first knife group 200 rotates 180° to switch between the storage state and the unfolded state, and the locking assembly can keep the first knife group 200 in the storage state or the unfolded state.

[0032] In the embodiment, the locking spring drives the rotation-stopping pin 405 to extend into the locking groove 403 and the guide groove 109 at the same time, and the guide groove 109 limits the rotation-stopping pin 405 in the circumferential direction. The center of the limiting partition plate 110 extends to form a guide column 113 toward the locking cavity 112, the guide column 113 is arranged parallel to the axial direction of the first rotating shaft 103, the rotation-stopping body 404 has an open-end cylindrical structure, the rotation-stopping body 404 includes an end plate 406, the end plate 406 is in sliding fit with the guide column 113 in the axial direction, the locking spring is sleeved on the guide column 113, and one end of the locking spring extends into the rotation-stopping body 404 and abuts against the end plate 406. In some other embodiments, the guide column 113 limits the end plate 406 in the circumferential direction, and the first rotating shaft 103 limits the rotation-stopping body 402 in the circumferential direction.

[0033] In the embodiment, the unlocking button 401 includes two contact feet 407, the limiting partition plate 110 includes two through holes 114, the contact feet 407 extend into the locking cavity 112 through the through holes 114, and the unlocking button 401 drives the rotation-stopping body 404 to move in the axial direction of the first rotating shaft 103 through the contact feet 407. The unlocking button 401 is in sliding fit with the unlocking cavity 111, the contact feet 407 include two barb portions 408, the two barb portions 408 are arranged opposite to each other, and the barb portions 408 abut against the limiting partition plate 110 to limit the unlocking button 401 from being pulled out.

[0034] The components of the unlocking assembly, such as the rotation-stopping body 404 and the locking spring, are accommodated in the specific cavities (the locking cavity 112 and the unlocking cavity 111) in the first rotating shaft 103, and the first rotating shaft 103 is a part of the shell 100. The cooperation of the components integrates the unlocking assembly inside the shell 100, which not only makes the overall structure of the knife more compact, but also protects the unlocking assembly from being damaged by external impact, wear and tear, and the like, thereby improving the reliability and service life of the unlocking assembly.

[0035] In the embodiment, the first rotating seat 203 is connected with a wrench portion 204, the wrench portion 204 is arranged in the radial direction of the first rotating seat 203, and the wrench portion 204 is arranged on the side where the first knife outlet 106 is located. When the user needs to rotate the first knife group 200 out of the accommodating cavity 105 to the unfolded state or rotate it back to the accommodating cavity from the unfolded state, the wrench portion 204 arranged in the radial direction can provide a longer force arm, so that the user can operate more easily and labor-savingly. The outer surface of the unlocking button 401 is provided with an unlocking mark to prompt the user to operate. The longitudinal end of the shell 100 is provided with a hanging hole 205 connected to the first rotating seat 203.

[0036] It is worth noting that the locking assembly designed in the patent, its working principle and structural features are also applicable to limiting the second knife group 300. Specifically, although the foregoing mainly takes the first knife group 200 as an example to explain the function of the locking assembly, that is, through the cooperation of the unlocking button 401, the locking spring, the rotation-stopping body 402 and the locking slot 403 arranged on the first knife holder 201, the locking and unlocking of the first knife group 200 are realized. However, if the second knife holder 301 is arranged with similar structural features as the first knife holder 201, such as corresponding locking slots 403 arranged on the second knife holder 301, and the structure of the rotation-stopping body 402 is adaptively adjusted so that it can cooperate with the locking slots 403 on the second knife holder 301, the locking assembly can also realize the limitation of the rotation of the second knife group 300 relative to the shell 100. Based on the principle that the above-mentioned locking assembly can also exert the limiting effect on the second knife group 300, in actual application, setting a group of locking assemblies acting on the first knife group 200 or setting two groups of locking assemblies acting on the first knife group 200 and the second knife group 300 respectively does not essentially change the core working principle and technical solution of the locking assembly involved in the patent, and the difference in the number of locking assemblies should not constitute a limitation on the protection scope of the patent.

[0037] The above embodiments are only used to illustrate the technical solutions of the utility model and not to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the utility model.
