Execute mode
Deferring to technique scheme, as shown in Figures 1 to 5, this utility model provides a kind of protection formula cutter, including
Hollow handle of a knife 1, offers outlet 2 on the upper surface of handle of a knife 1, and handle of a knife 1 mounted inside has the cutter head that can stretch out from outlet 2
11；Being equipped with handle 5 by rotating shaft 3 on the outer wall of described handle of a knife 1, handle 5 passes through depression bar 10 and is arranged within handle of a knife 1
Drive mechanism connects；During by lower handle 5, under the effect of drive mechanism, cutter head 11 stretches out in outlet 2.
Design ultimate principle of the present utility model is, when needs use cutter, by the cutter head 11 of cutter from handle of a knife 1
In stretch out, and during without using, cutter head 11 then remains in the state within handle of a knife 1, thus can be effectively prevented not
During use, people is damaged by cutter head 11.
The basic structure of these cutter includes a hollow handle of a knife 1, and handle of a knife 1 can be various shape, for example, cylinder
Shape.Handle of a knife 1 internal activity formula is provided with cutter head 11, has a handle 5 on handle of a knife 1 outer wall.As depicted in figs. 1 and 2, handle 5
One end tilts, generally arc-shaped structure, more conforms to the gripping custom of people.It addition, it is circumferentially square on the outer wall of handle of a knife 1
To offering groove 6, groove 6 is provided with finger ring 4；During use, by finger through finger ring 4, after passing, make the front end of finger
Holding handle 5, now finger tip is firmly, and by handle 5 near the pressing of the direction of handle of a knife 1, then depression bar 10 extend into handle of a knife 1 inside,
Under the effect of drive mechanism, cutter head 11 stretches out in outlet 2；And when not in use, cutter head 11 remains within handle of a knife 1
State, thereby ensures that the use safety of these cutter.
As in figure 2 it is shown, be provided with the first spring 9 between the outer wall of handle 5 and handle of a knife 1, handle of a knife 1 is set with spacing collar
7, part handle 5 is overlapped therein by spacing collar 7；During the effect of the first spring 9, assist handle 5 resets, time i.e. without using, and hands
Handle 5 rains in the effect of the first spring 9 and maintains a certain distance between handle of a knife 1.During the effect of spacing collar 7, when needs make for a long time
During with cutter head 11, always relatively elaborate according to handle 5, therefore spacing collar 7 can be made to be enclosed within handle 5 spacing collar 7 slide downward
One end of upper tilting, so can keep the handle 5 pressed state to depression bar 10, then cutter head 11 is just outside always situated in handle of a knife 1.
When cancelling this state, then have only to move up spacing collar 7.Guide groove 8 is offered vertically on handle of a knife 1 outer wall, described
Spacing collar 7 be connected with the guide pad being assemblied in guide groove 8.Guide groove 8 plays the effect limiting spacing collar 7, is also used for fixing limit
Position circle 7.
As in figure 2 it is shown, handle of a knife 1 internal symmetry is provided with slide rail 14, slide rail 14 is equipped with slide block 13, described cutter head
11 are connected on slide block 13 by knife bar 12, are provided with the second spring 15 between slide block 13 and handle of a knife 1 inner bottom surface.In transmission
Under the effect of mechanism, promote slide block 13 to move upward, cutter head 11 is released handle of a knife 1.And after losing motive force, then at the second spring
Under the effect of 15, cutter head 11 is retracted in handle of a knife 1, restPoses.
This programme proposes the structure of two kinds of drive mechanisms, the first as shown in Figure 4:
Drive mechanism includes that the first tooth bar 18, the first tooth bar 18 are connected with described depression bar 10, the first tooth bar 18 and one
The first travelling gear 17 being assemblied on the first bull stick 19 engages；It is set with the first conical gear on the first described bull stick 19
20, and it is set with the second conical gear 23 and the second travelling gear on second bull stick 16 being perpendicular to the first bull stick 19
21, wherein the second conical gear 23 engages with the first conical gear 20, the second travelling gear 21 be arranged on bottom slide block 13
Second tooth bar 22 engages.
Owing to by lower handle 5, extending above from handle of a knife 1 with cutter head 11 is the linear motion in two vertical direction, in order to
Realize the conversion that the two side moves upward, be provided with rack-and-pinion matching mechanism, including a pair travelling gear, a pair circular cone tooth
Wheel and a pair tooth bar, a pair bull stick.Wherein first conical gear the 20, second conical gear 23 is for converting on different directions
Motion, the cooperation of the first travelling gear 17 and the cooperation of the first tooth bar 18, second travelling gear the 21, second tooth bar 22 then will circle
Week, conversion of motion was for moving along a straight line, and was achieved in, by lower handle 5, cutter head 11 being released the purpose of handle of a knife 1.
The second drive mechanism is as it is shown in figure 5, drive mechanism includes a U-tube 25, and the two ends of U-tube 25 are provided with
Piston, is full of hydraulic oil between piston；One of them piston is connected with described depression bar 10, another piston by push rod 24 with
Slide block 13 connects.This structure is then to utilize the hydraulic oil flowed to realize the transmission of power on different directions, and structure is simpler.
