Before in detail explaining any structure of the present utility model, should be understood that the utility model is not limited to set forth in the following description in its application or accompanying drawing below shown in the structure of parts and the details of layout.The utility model can have other structure and can be put into practice or realize in every way.
Detailed description of the invention
Referring now to Fig. 1, show the metal scissors 10 according to an embodiment of the present utility model.Scissors 10 is between open and close state, to be operated the hand-operated tools for the workpiece of cutting metal and other materials by user.Those skilled in the art will recognize that according to hand-operated tools of the present utility model can also be the instrument for other purposes, for example sew scissors or the scissors for food materials.
As shown in Figure 1, scissors 10 has the first cutting out section and second cutting out section pivotally connected with the first cutting out section substantially.The first cutting out section comprises the first jaw member 102, first handle 116, first handle pivot pin 124, the first hand grip portion 120, the first blade portion 106 and the first extension 108.The second cutting out section comprises the second jaw member 104, the second blade portion 110, second handle 118, the second hand grip portion 122, second handle pivot pin 126 and the second extension 112.Scissors 10 also comprises clamp pintle assembly 114, central pivot pin 128, torsion spring 130 and locking mechanism 132.
Should be understood that the above basic structure of only describing scissors.Those skilled in the art can easily understand, is not departing from spiritual scope of the present utility model, and scissors can have different designs or in conjunction with further feature.
Fig. 2 illustrates the exploded view of the locking mechanism of scissors.Locking mechanism 132 comprises actuator 134, spring 136 and lockplate 138.Actuator 134 has the base portion 140, the first protuberance 142 and the second protuberance 144 that arrange vertically.Wherein, the cross-sectional area of described base portion 140 is large compared with the cross-sectional area of the first protuberance 142, and the cross-sectional area of described the first protuberance 142 is large compared with the cross-sectional area of the second protuberance 144.Actuator 134 also comprises the groove 146 of the one end 148 for receiving lockplate 138.Spring 136 is enclosed within on the end 148 of lockplate 138.When end 148 is received in groove 146 when interior, the bottom surface 150 of actuator 134 is near spring 136, and spring 136 is near the edge 152 of lockplate 138.Lockplate 138 comprises that part edge open the first opening 154 and edge seal the second opening 156 completely.The first opening 154 and the second opening 156 are for receiving the first locking pivot pin 158 and the second locking pivot pin 160.Wherein, lockplate 138 is pivotally connected to handle 116 regularly by the first opening 154 and the first locking pivot pin 158.
Torsion spring 130 is called again the second biasing device in this embodiment, and described the second biasing device is suitable for carrying out lockplate 138 to carry out bias voltage along second direction, thereby makes in the time of lock-out state lockplate 138 in the position shown in Fig. 4.Spring 136 is called again the first biasing device, and described the first biasing device is suitable for carrying out actuator 134 to carry out bias voltage along first direction, thereby makes in the time of lock-out state lockplate 138 in the position shown in Fig. 5 A and 5B.
Fig. 3 illustrates the part side view of scissors handle.On handle 116, have and also there is opening 162, thereby actuator 134 makes user can contact and operate this actuator from opening 162 is outwards outstanding.
Configuration when Fig. 4 to 5D shows scissors and is in the lock state.Under this state, the second locking pivot pin 160 is received in the second opening 156, and therefore lockplate 138 is connected in handle 116 and handle 118 simultaneously, thereby makes handle 116 and the handle 118 can not be relative to each other pivoted.Spring 136 is along first direction bias voltage actuator 134.So, base portion 140 surfaces of actuator 134 are against the inner surface of handle and the first protuberance 142 of actuator 134 coordinates with opening 162.
Fig. 6 to 7B shows the configuration of scissors in the time of released state.At this state, lockplate 138 is along direction B pivotable, and the second opening 156 leaves the second locking pivot pin 160.Torsion spring 130 bias voltage lockplates 138.In addition, the first protuberance 142 surfaces of actuator 134 are against the inner surface of handle and the second protuberance 144 coordinates with opening 162.
In the time of operation, if user wants to move to unlocked position from latched position, first user will press hydraulic actuator 134 along the direction A in Fig. 4 (opposite direction of described first direction), to overcome the bias voltage of spring 136 and to make the first protuberance 142 of actuator 134 depart from and coordinate with handle openings 162.Then user along direction B actuated actuators 134 to make lockplate 138 along direction B pivotable, thereby be biased in released state by torsion spring 130.
In claim below, set forth various feature of the present utility model.
