Description

One kind visualization penknife

Technical field

The present invention relates to the technical field of penknife structure, specially a kind of visualization penknife.

Background technology

Existing penknife, is shown in Fig. 1, when needs are cut, first pulls open a mechanism 1 ' is pinched, until gag lever post 2 ' is blocked, behaviour Make to pinch a mechanism 1 ', pen is put into, and clamp pen, hold handle 3 ', and rotate, hob head 4 ' excites gag lever post 2 ', makes folder Song Bi mechanisms 1 can inside deliver in the case where extension spring 5 ', pull bar 6 ' are acted on, and the now rotation of handle also drives hob head 4 ' to rotate, Hobboing cutter 7 ' is fixed on hob head 4 ', and the tooth on hobboing cutter 7 ' is engaged with the tooth on hob head fixed block, forms planetary gear, makes hobboing cutter 7 ' reverse, and so as to the blade on hobboing cutter 7 ' starts sharpening pencil, after having cut, also need operation to pinch a mechanism 1 ', take out pencil, its The position of people's multi-pass operation pen with means for holding it in right position is needed when cutting, so that it is guaranteed that enter pen can be smoothed out so that the operation of penknife is numerous It is trivial, reduce and cut an efficiency, and a situation is cut due to cannot see internal pencil, typically will please correct to into inner casing most Marginal position is guaranteeing that cutting pen completes so that waste the available part of pencil.

The content of the invention

For the problems referred to above, the invention provides a kind of visualization penknife, when it causes to cut in enter automatically pen, until Cut pen to terminate to take out pencil so that it is simple to cut a step, and cut during pen, cut a position and can be arrived with real-time monitored so that cut To length available so that the available partial variable-length of pencil, pencil has been saved.

One kind visualization penknife, it is characterised in that include：

One shell, it has the first wall portion and the second wall portion positioned opposite, and first wall portion is provided with pass through aperture；

Specific embodiment

The manual penknife of one kind visualization, is shown in Fig. 2～Fig. 8, including：One shell 1, it has one first wall positioned opposite The wall portion 3 of portion 2 and 1 second, the first wall portion 2 is provided with pass through aperture 4；

One knife rest 5, it is arranged on inside shell 2, knife rest 5 can in the space between the first wall portion 3 and the second wall portion 3 to And moved along a straight line on close/direction away from through hole 4；

One Flexible element, it is arranged on the inside of shell 1, to provide the elastic force for promoting the homing of knife rest 5；

One cutter module, it is arranged in knife rest 5, and cutter 7 is provided with cutter module；And

One visual window 22, it is arranged on the shell 1, and the visual window 22 is relative to the window inside shell 1 Cover the cutter under cutting pen state.

Visual window 22 is located at the position directly above of the cutter 7 under cutting pen state；Through can window can observe it is described Cutter 7 inside shell 1 cuts a situation；

Visual window is located at the upper surface position of the shell 1 for closing on second wall portion 3；

It also includes a pencil holding mechanism 8, and pencil holding mechanism 8 is arranged in shell 1 and neighbouring through hole 4, and pencil holding mechanism 8 sets It is equipped with one and enters pen mouth 9 corresponding to through hole 4；

The work centre axis 20 of pencil holding mechanism 8 and knife rest 5 is in same straight line；The center of the visual window is located at institute State the surface of work centre axis 20；

Cutter module includes a tool rest 6, and cutter 7 is arranged in tool rest 6, and tool rest 6 is arranged in knife rest 5；

Flexible element includes multiple springs 10；

The bracing frame of knife rest 5 including both sides, front support stand 11 respectively near pencil holding mechanism 8, away from pencil holding mechanism 8 Rear support stand 12, is connected between supported on both sides frame by three connecting rods 13, and rear support stand 12 and three connecting rods 13 are one Overall, spring 10 is set in after corresponding connecting rod 13, and front support stand 11 is fixedly connected the connecting rod of correspondence position by screw 13, so as to form frame structure；

The proximal location of the close connecting rod 13 inside shell 1 is provided with position guiding groove 15, and position guiding groove 15 corresponds to connecting rod 13 arrangements, the end of position guiding groove 15 is located in the medium position of the knife rest 5 under cutting pen state, and the end of position guiding groove 15 is bullet The positioning end face 16 of one end of spring；

A spring 10 is set with every connecting rod 13, the two ends of each spring 10 are mounted on respectively inside shell 1 The positioning end face 16 of position guiding groove 15, the inwall of the front support stand 11 of knife rest 5, the telescopic direction of spring 10 is parallel to knife rest 5 Work centre axis；

Front support stand 11 corresponds to the orthographic projection position into pen mouth 9 and is provided with orthographic projection through hole 17, and pen runs through into pen mouth 9th, press cutter 7 after orthographic projection through hole 17, until drive whole knife rest 5 along position guiding groove 15 toward its position the straight line of end face 16 to After move, until needing the length for cutting pen all to stretch into inside shell 1.

The manual penknife also includes bits collecting box 14, and the lower section of shell 1 is provided with bits collecting box 14, the bottom connection of shell 1 To the internal cavity of bits collecting box 14, bits collecting box 14 is collected pen and is considered to be worth doing, and detachably；

The Power Drive Unit of manual penknife is handle construction 18, and the second wall portion 3 of shell 1 is disposed with the handle of evagination Structure 18, handle construction 18 connects the input of tool rest 6 by connecting rod 19, when the length of connecting rod 19 guarantees that knife rest 5 moves along a straight line The connection of the input of connecting rod 19 and tool rest 6 is effective.

Preferably, knife rest 5 is hob arbor carriage, and tool rest 6 is hob holder, and cutter 7 is hobboing cutter.

In specific embodiment, when penknife is electro-motion pencil sharpener, Power Drive Unit (is not drawn for motor configuration in figure Go out, belong to existing mature technology), the output end of motor configuration connects the input of connecting rod, and the length of connecting rod guarantees knife rest straight line The connection of the input of connecting rod and tool rest is effective during motion.

Concrete operating principle is as follows：

Pencil holding mechanism 8 is put in pen 21 under open mode, and pen 21 promotes the leading in rear support stand 12 of whole knife rest 2 Backward (position guiding groove quantity is not limited) is moved in the groove 10 of position, length need to be cut and fully entered after housing, pencil holding mechanism 8 is locked；Pen 21 Position to be cut now can see that cutter 7, pencil 21 corresponding to the cutter of cutter module through visual window 22, now drive knife The band 7 pairs of pens 21 of cutter of seat 6 carry out cutting pen, in the presence of spring 9, the cutting of the side of tool rest 6, and side supplements and machines away the remaining of pencil Amount, is slowly moved along, and whole penknife structure is automatically replenished the cutting output of the sharpening pencil of cutter 7, until cut pen completing, pen clip machine Structure 8 and enter a structure automatically and complete to separate, when it causes to cut only need to that pen 21 is put in penknife, then can be cut Pen, terminate to take out pencil until cutting pen so that cut that a step is simple, the convenience for cutting pen is good, and due to visual window 22 relative to Visual range inside shell 1 covers the cutter 7 under cutting pen state so that cutting a position can be arrived with real-time monitored, Pencil sharper is to length available so that the available partial variable-length of pencil, has saved pencil.

The specific embodiment of the present invention has been described in detail above, but content is only the preferable enforcement of the invention Example, it is impossible to be considered as the practical range for limiting the invention.All impartial changes made according to the invention application range Change and improve etc., all should still belong within this patent covering scope.
