Abstract

The utility model relates to a manual cutting tool, particularly a pair of manual rotary scissors for cutting cloth, paper, artificial leather, plastic cloth and other thin soft materials. The scissors are composed of handles, an outer shell, a bracket, an elevating arc, a driving gear, circular knife blades, etc. The utility model is capable of continuously and smoothly cutting articles, with high speed and flexible turning, and is safe and labor-saving during use. The utility model is particularly suitable for cutting long-distance articles and is applicable to family sewing, tailoring, shops, factories, etc. where cutting needs to be carried out. The utility model has the advantages of simple structure and convenient manufacture, and can be produced by general processing plants of plastic products, township enterprises or individuals.

Description

Rotary shears

The utility model relates to a kind of hand cutting instrument, particularly a kind of manual rotation scissors that is suitable for cutting cloth, paper, artificial leather, Polypropylence Sheet and thin softwood matter thereof.

The common scissors that uses is when the cutting article at present, and what take is the interrupted cutting mode that article are provoked in short distance, and cutting speed is slow, and sanction line error is big, and during operation, labour intensity is big, and it is time-consuming to require great effort, and the cutting time one is long, and wrist and arm easily cause fatigue.

The purpose of this utility model provides a kind of novel manual rotation scissors, its can continuously smooth ground cutting article, it is little to cut out the line error, speed is fast, safety labor-saving, the not enough aspect when having overcome common scissors use.

Principle of the present utility model is cut according to point and is cut laborsaving, rolling cut than line and design than vertical cut is laborsaving, adopts break bar to carry out rolling cut sheet material.

The utility model is achieved in that this scissors is made of last lower handle, shell, support, sector gear, travelling gear, two disc cutters.It is characterized in that: upper handle and shell are integral, and lower handle is movably connected on the upper handle by bearing pin, and sector gear and travelling gear are fixed on a side of shell by support, are connected by steel wire rope between lower handle and the sector gear.The disc cutter gear fixedly is assemblied on the same bearing pin with the active disc cutter.Initiatively disc cutter and passive disc cutter are fixed within the shell by the bearing pin at disc cutter center, and disc cutter is parallel to each other and is close to and can rotates, and the parallel tangent part of blade of active disc cutter and passive disc cutter is coincide, and reach clipping function.

Below with drawings and Examples the utility model is illustrated in detail

Fig. 1 is the structural representation of the manual rotation scissors that the utility model proposed.

Among the figure: 1. upper handle 2. lower handles 3. bearing pins 4. steel wire ropes 5. sector gears 6. travelling gears 7. gear shafts 8. sliding trays 9. disc cutter gears 10. disc cutters 11. passive disc cutter 12. back-moving springs 13. supports 14. shells 15. bearing pins 16. bearing pins initiatively

As shown in Figure 1: manually rotate scissors by last lower handle (1) (2), shell (14), support (13), sector gear (5), travelling gear (6), initiatively disc cutter (10) and passive disc cutter (11) constitute, it is characterized in that upper handle (1) and shell (14) are integral, lower handle (2) is movably connected on the upper handle (1) by bearing pin (3), sector gear (5) and travelling gear (6) are fixed on a side of shell (14) by support (13), be connected by steel wire rope (4) between lower handle (2) and the sector gear (5), disc cutter gear (9) fixedly is assemblied on the same bearing pin (15) with disc cutter (10) initiatively.Initiatively disc cutter (10) and passive disc cutter (11) are fixed within the shell (14) by the bearing pin (15) (16) at disc cutter center, initiatively disc cutter (10) and passive disc cutter (11) are parallel to each other and are close to and can rotate, the parallel tangent part of blade is coincide, and reaches clipping function.Disc cutter (10) (11), disc cutter gear (9), gear shaft (7) adopt steel to make, and handle (1) (2), shell (14), gear (5) (6) and support (13) can adopt aluminium alloy, engineering plastics or nylon material.

When manually the rotation scissors is worked, when holding handle (1) (2), affect sector gear (5) by steel wire rope (4), sector gear (5) clockwise rotates, rotate counterclockwise with its meshing travelling gear (6), driving initiatively by disc cutter gear (9) again, disc cutter (10) turns clockwise, when the article of wanting cutting are delivered to the tangent anastomosis of disc cutter (10) (11) and contacted blade, rotation along with active disc cutter (10), passive disc cutter (11) is also along with rotating counterclockwise, the rolling cut order is progressive, has finished the cutting of article.When release handle (1) (2), back-moving spring (12) resets sector gear (5) and lower handle (2), rotating counterclockwise of sector gear (5), the gear shaft (7) of travelling gear (6) is moved to the left along sliding tray (8), broken away from disc cutter gear (9), therefore initiatively disc cutter (10) can not reverse.When the handle of holding with a firm grip once more (1) (2), carry out next cutting process again.

Model machine by the utility model provides carries out practical operation, shows laborsaving the saving time of its energy, uses flexibly, and safe and reliable, it is level and smooth to cut out line, has reduced shearing error, is particularly suitable for the cutting cloth, paper, artificial leather, Polypropylence Sheet and other thin softwood matter.This scissor construction is simple, and is easy to make, suitable promoting the use of.

Claims

1, a kind of manual rotation scissors, by last lower handle (1) (2), shell (14), support (13), sector gear (5), travelling gear (6), initiatively disc cutter (10) and passive disc cutter (11) constitute, it is characterized in that upper handle (1) and shell (14) are integral, lower handle (2) is movably connected on the upper handle (1) by bearing pin (3), sector gear (5) and travelling gear (6) are fixed on a side of shell (14) by support (13), be connected by steel wire rope (4) between lower handle (2) and the sector gear (5), disc cutter gear (9) fixedly is assemblied on the same bearing pin (15) with active disc cutter (10), and initiatively disc cutter (10) and passive disc cutter (11) are fixed within the shell (14) by the bearing pin (15) (16) at disc cutter center.
