Description

  The present invention relates to a function kite in which a function capable of cutting according to the application is added to a conventional kite.

  In general, a kite is a tool that allows a pair of cutting blades to cross each other and simply sever the sandwiched object, and has a history of improving sharpness and ease of cutting just like a knife. There are many types of cutting blades that are characterized by their shape, size, and cutting method. However, there is a need for a kite that is not only sharp and easy to cut, but also has functions that are useful for adapting to the application, and that pursues improved convenience and work efficiency.

  In the conventional paper bag, there was no improvement made by taking a step forward from the functional aspect, such as cutting two sheets of paper into different shapes by cutting once and preventing the paper from slipping. For example, when opening a drug bag, it is difficult to open with fingers because the cuts are aligned, and it is difficult to drink. It was easy to escape, and it was difficult to cut due to slipping on the heel, and skill was required to cut well.

  Furthermore, as a problem associated with the cocoon, for example, the laminate pack used for retort food could not be stored hygienically when opened, and in gardening pruning work, For the purpose of preventing infection, it is necessary to replace the vines for each tree or to disinfect them later, which is a costly and troublesome work.

  An object of the present invention is to solve such a problem by adding a function suited to the application to a conventional scissors, and to provide a function scissors that can improve the convenience and efficiency of cutting work.

  In order to achieve the above object, according to a first aspect of the present invention, a pair of cutting blades that are pivotally mounted so as to be able to open and close and intersect each other are positioned in front of the cutting edge of at least one of the pair of cutting blades. A friction rod is arranged parallel to the workpiece, and a means for sliding and friction with the workpiece prior to cutting is provided, and one end of the friction rod is pivotally attached to the cutting blade together with the cutting blade. It can be moved and locked between the sliding contact position and the non-sliding position. As a result, when the workpieces are stacked in two, the friction rod slides and rubs against one of the overlapping ones prior to cutting, resulting in a force to pull the one between the intersecting cutting edges. As a result, the direction in which they are cut slightly changes, so that the cuts do not overlap even if they are cut once, and it is possible to cut them in a shifted shape. Moreover, it can be used also as a general scissors by moving the said friction rod from the front of a blade edge to the vicinity of the peak of the other cutting blade, and latching.

  According to a second aspect of the present invention, a pipe-shaped cover for adjusting friction is attached to the friction rod. Thereby, the friction at the time of sliding contact with a to-be-cut object can be adjusted with the material, shape, and length of this pipe, and a cut shape and a cutting gap width can be set as needed. Incidentally, when the object to be cut is in a bag shape, the cut ends can be cut into a concave shape and a convex shape since the end portions at the start and end of the cut are closed.

  According to a third aspect of the present invention, the friction rod is provided with a coiled cover for preventing cutting and escape. As a result, this coil is interposed between the friction rod and the cutting blade, and serves as a partition and presser for the object to be cut. Therefore, it is possible to prevent wrinkles caused by the escape of the workpiece.

  According to a fourth aspect of the present invention, a pipe heater for hot welding is attached to the friction rod. Accordingly, prior to cutting, the heater comes into sliding contact with the object to be cut, and when the object to be cut is a laminate pack or the like, it is possible to seal while pressing the cut edge on the side to be cut off simultaneously with the cutting.

  In claim 5, a pipe-like shower nozzle for spraying is attached to the friction rod. Accordingly, it is possible to pump the vapor or liquid to the nozzle and spray the vapor or liquid around the cutting edge or the cut edge simultaneously with the cutting.

  The function bag of the present invention has the effects as described below.

  In the case where two workpieces are stacked, the cut edge can be shifted and separated by the friction rod that comes in sliding contact with each other. Further, the friction rod can be used as a general scissors by being locked at a position where it does not slide against the object to be cut.

  Furthermore, in the case of a medicine bag or the like, it is possible to cut the cut into a concave shape and a convex shape by attaching a pipe-like cover to the friction rod and adjusting the friction during sliding contact. Since the cut surface is slanted when opened in a cylindrical shape, it is not necessary to warp the head backward by tilting the medicine bag and hitting the convex side against the mouth, even in elderly people It becomes easy to drink up.

  Next, even when the object to be cut is curled and bundled like hair or thick cloth, by attaching a coiled cover to the friction rod, it can be cut easily without slipping Is possible. In addition, the crossing of both cutting edges is in the most dangerous cage, and the present invention is highly safe because at least one of the cutting edges is covered by the friction rod. For example, when used for cutting a pet, It is safe because there is little risk of injury even if you move a little.

  Next, when opening a laminate pack used in retort foods, etc., by attaching a pipe heater to the friction rod, for example, if you want to leave half, the contents are distributed to both ends beforehand and the center is cut By doing so, the pipe-shaped heater rubs against the pack and can handle the contents that are left at the same time as cutting and heat-seal while pressing the cut, thus preventing seal leakage due to the pinching of the contents and air It becomes possible to complete the seal hygienically without contact and continue to store it. Moreover, if this is used in horticulture or the like, thermal sterilization of the cutting edge and cut edge can be performed simultaneously with cutting, so that infection can be effectively prevented.

  Next, when using in the pruning operation, a pipe-shaped shower nozzle is attached to the friction rod, and a high-temperature steam or a disinfecting liquid that has been pressurized is sent to and sprayed to the pruning operation and the cutting edge of the cutting edge or branch. Since the surrounding sterilization work can proceed simultaneously, an efficient work can be performed.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  FIG. 1 is an exploded perspective view showing an embodiment of the present invention, which is composed of a pair of cutting blades 1 and 2 with a handle, a friction rod 3, an eccentric collar 4, and an adjustment knob 5 fitted to this, The shaft bolt 6 and the shaft nut 7 are assembled in the respective rotation shaft holes and disassembled so as to be assembled. These are pivotally mounted around a fulcrum. Incidentally, in the case of a function rod, the friction rod handle 3d is pinched to lock the locking portion 3c into the locked hole 2c of the cutting blade 2, and the friction rod rod-shaped portion 3a is moved in front of the cutting edge of the cutting blade 2. To use. Similarly, by moving the locking portion 3c to the locked hole 1c of the cutting blade 1 this time, the friction rod rod-shaped portion 3a stays in the vicinity of the peak of the cutting blade 1, so that it does not come into sliding contact with the object to be cut. It becomes possible to use it as a bag. The friction rod 3 is a material excellent in elasticity and wear resistance, and a material with a rough surface is suitable. For example, a stainless steel spring material is used to improve the friction effect by using a hairline finish. May be.

  FIG. 2 is an enlarged cross-sectional view of a rotating shaft portion that is a fulcrum of this function rod. A loop portion 3b of the friction rod 3 is arranged on the side surface of the cutting blade 2 that is in sliding contact with the cutting blade 1, and this is shown as an eccentric collar. While being pressed by the adjusting knob 5 fitted with 4, the shaft bolt 6 and the shaft nut 7 are tightened from both sides, and the friction rod bar 3a is always urged in the direction of pressing toward the cutting blade 1 side.

  The fulcrum portion can be adjusted so that the cutting edge and the friction rod are kept parallel even if there is a difference in the thickness of the pipe or coil attached to the friction rod-like portion 3a, and the adjustment knob 5 is turned. As a result, the loop portion 3b around the eccentric collar 4 having the rotation shaft hole at a position shifted from the center moves the rotation shaft, and the distance from the fulcrum of the friction rod is determined according to the thickness of the object to be mounted. It becomes possible to adjust. Further, since one surface of the eccentric collar 4 of the rotating shaft adjusting mechanism forms a swash plate, the adjusting knob 5 fitted therewith restricts the clearance in which the loop portion 3b is accommodated according to the rotation of the knob. The sliding contact pressure between the friction rod and the object to be cut can also be adjusted.

  The eccentric collar 4 and the adjustment knob 5 of the rotating shaft adjustment mechanism may be combined and integrated, and in this case, the flange portion serving as the pressure contact surface with the loop portion 3b is inclined, or a projection in place of it is used as a part. There is also a method of attaching. The plurality of functions that can be selected by the present invention may be a dedicated bag having each function independently. In this case, the rotating shaft adjusting mechanism is unnecessary, so that the friction rod simply having a rotating shaft hole is provided. May be made by press working or the like. Further, friction rods may be axially attached from both sides of the scissors and arranged in front of both blade edges. In addition, a washer having the same diameter as the loop portion 3 b may be inserted between the cutting blade 2 and the eccentric collar 4 in order to improve the sliding feeling as a general ridge.

  FIG. 3 is a cross-sectional view immediately before the pipe cover 31 is attached to the friction rod 3 and the medicine bag 8 is cut, and the pipe cover 31 placed on the outer periphery of the friction rod 3 is positioned in front of the cutting edge 2 a of the cutting blade 2. FIG. 2 shows a state in which the upper side of the bag 8a is gradually rubbed in sliding contact with the medicine bag prior to cutting.

  FIG. 4 is a cross-sectional view when the medicine bag 8 is started to be cut, and the friction-adjusting pipe-shaped cover 31 further rubs the single bag upper side 8a and drags it between the blade edges just before the intersection, and then continues to the cutting blade. A state in which the upper side and the lower side of the bag are cut off by crossing 1 and 2 is shown.

  FIG. 5 is an upper side view when the medicine bag 8 has been cut and shows that the bag upper side 8a and the bag lower side 8b are cut into a concave shape and a convex shape, respectively, and cut into easy-to-drink cuts. Moreover, since the last part by which the medicine bag 8 was cut | disconnected is pinched | interposed and hold | maintained between the cutting blade 1 and the pipe-shaped cover 31, it does not scatter. The effect of this pipe-shaped cover can be enhanced by selecting a material with good friction compatibility in accordance with the material of the object to be cut, such as a resin pipe such as silicone or synthetic rubber, or a metal pipe processed by knurling. it can.

  FIG. 6 is a lower side view of the friction rod 3 with the coiled cover 32 attached thereto, and the coiled cover 32 and the cutting blade 1 are partitioned by the height of the coil wire and the pitch width of the spiral. Since the space is secured, in the case of hair etc., this partition prevents the movement of the object to be cut, and in the case of fabric etc., the coil itself acts as a presser to stop the fabric escape. Therefore, cutting becomes easy. The coiled cover 32 is suitably fitted with a slightly larger inner diameter than the friction rod using a stainless steel coil spring or the like. It is better to reduce the diameter of the part.

  FIG. 7 is a perspective view of a state in which the pipe-shaped heater 33 is attached to the friction rod 3. This heater is fixed with a screw or the like from the tip of the friction rod 3, and then the set temperature can be maintained by passing electricity. Yes, in the case of a laminate pack or the like, the heater comes into sliding contact prior to cutting, and it is possible to perform welding on the side that is heated while pressing the cut and is left simultaneously with cutting. In addition, this heater can be used for heat sterilization of the cutting edge and cut edge of pruning shears in horticulture and the like, and it becomes easier to handle if the shape of the cutting edge is changed to that for horticulture and the heater is matched to it.

  FIG. 8 is a perspective view of a state in which the pipe-shaped shower nozzle 34 is attached to the friction rod 3, which is different from the normal function use in that the friction rod engagement portion 3 c is engaged with the engagement hole 1 c of the cutting blade 1. The state where the nozzle is moved and locked is shown with the nozzle facing upward. This nozzle is composed of an inner and outer double pipe, and the inner diameter of the inner pipe is slightly larger than that of the friction rod 3, and is inserted from the tip of the friction rod 3 so as to be rotatable. A plurality of nozzles are provided, and pressurized high-temperature steam, disinfectant, or the like can be fed into the space of the inner and outer pipes and sprayed in a shower shape toward the cutting edges 1a and 2a. In some cases, the friction rod locking portion 3c can be moved to the locked hole 2c to rotate the nozzle downward for use. Moreover, it becomes easier to handle if the shape of the cutting edge is changed to gardening.
