Detailed description of the invention

By specific embodiment, the invention will be further described below in conjunction with the accompanying drawings.

As it is shown on figure 3, the pencil holding mechanism of described a kind of penknife, including be provided with chuck 6, jump ring 7, The pen clip device of claw 8 and the actuation button 1 being connected with chuck 6, described actuation button 1 includes on one Button 2, described upper button 2 is cylinder, and the bottom face of upper button 2 is evenly distributed with six around circular edge The upper sawtooth 21 being connected, the crown of described six upper sawtooth 21 is in and is perpendicular to button axially direction epirelief Go out its face of cylinder；The underface of described upper button 2 is a lower button 3, as shown in Figure 6, described lower button 3 are provided with a circle positive stop lug boss 31, the upper surface of lower button 3 for cylinder and bottom around the outer ring on the face of cylinder Being evenly distributed with six connected lower sawtooth 32 around circular edge, under described each two, sawtooth 32 is under being perpendicular to A sliver 33 protruding its face of cylinder, described every sliver 33 upper it is provided with in button 3 axially direction Holding and laminating concordant with one of them toothed surface of corresponding lower sawtooth 32, lower end extends to positive stop lug boss 31, institute State sliver 33 to be evenly distributed on the face of cylinder of lower button 3；Described upper sawtooth 21 and the profile of tooth of lower sawtooth 32 Matching and conflict, described upper button 2 is arranged with a fairlead 4, such as figure jointly with the outer ring of lower button 3 Shown in 4, the inwall of described fairlead 4 matches with the face of cylinder of upper button 2 and lower button 3, described guiding Uniformly offering six grooves 41 on the inwall of set 4, the top of groove 41 up to fairlead 4, down to guiding The set bottom face of 4 and concordant with bottom face, described groove 41 just matches with sliver 33, thus, leads Inwall to set 4 is uniformly divided into six projections 42 by six grooves 41, and the bottom of these six projections 42 is all provided with It is calculated as the inclined-plane matched with sliver 33 upper surface, in described six grooves 41 in a groove 41 The most within it being provided with a fixture block 43 parallel with groove 41 on wall, the bottom of described fixture block 43 is one The inclined-plane matched with sliver 33 upper surface, the bottom of described fixture block 43 is higher than the bottom of projection 42, such as figure Shown in 5；The top of described upper button 2 is provided with a pressure cap 5, and the diameter of described pressure cap 5 is more than fairlead The diameter of 4, the described bottom of lower button 3 is connected with the chuck 6 of pen clip device.
