Description

  The present invention relates to a coating stripper which removes a coating of a coated wire terminal portion in a desired range and exposes a core wire of the coated wire.

  The covering stripper is generally a saddle type with a handle (see, for example, Patent Document 1). When both the pair of clipped portions opened and closed by the pair of handles are closed, One pair or a plurality of pairs of cutting blades having different diameters for forming ripped holes are provided. After one end of the coated wire is sandwiched between the cutting blades of the clip part by closing the pair of handles, the cutting blade is cut into the cover to make it close to or in a state close to it. By pulling to one end side, the coating on one end side is peeled off from the core wire from the position where the cutting blade cuts, and the end portion of the core wire can be exposed.

On the other hand, as another type of stripping stripper, it has a pair of operating levers whose bases are connected by a shaft and can be opened and closed on the tip side, and the stripping hole forming part is opposed to both tip parts of these operating levers A wire guide is attached to the tip end side of one stripping forming part, and a covered wire is inserted between the stripping hole forming parts along the wire guide from the tip side and attached to the opening side by a spring. By gripping the biased operating lever and closing it, the stripping hole forming part abuts and the stripping hole part slightly larger than the diameter of the core wire formed between the two parts is covered with the coated wire. After cutting and making it close to the cut state, pull the pair of control levers as they are toward the base side of the covered wire, and cover it Peeled off the covering of the tip end of the coated wire from the core wire position so the cut is also known that so as to expose the end portion of the core wire (e.g., see Patent Document 2.).

  However, the one disclosed in Patent Document 1 has a simple configuration and can be provided at low cost. However, after the handle is gripped and a cutting blade for forming a stripping hole is cut by a closing operation, the coating stripper is parallelized. Since it is moved to peel off the coating, even if there is no problem in stripping the thin and soft coating, it is difficult to apply force to stripping the thick and tough coating and the workability is poor.

  On the other hand, what is disclosed in Patent Document 2 is a cutting blade in which upper-side stripping hole forming portions provided at the distal ends of a pair of operating levers connected so that bases can be opened and closed by a shaft come into contact with each other. Since each stripping hole forming part is separated from each other with the opening and closing of each operation lever, it is perpendicular from the posture inclined with respect to the axis of the covered wire from before cutting into the coating until the end of cutting. Changes to a proper posture. For this reason, the cutting trajectory of the cutting blade tip into the coating becomes an arc shape, and the cutting edge moves and pushes away the opposite tip side at the cutting position of the coating as the cutting progresses. However, it requires more work force, and the thicker and stronger the coating, the more problematic it becomes. At the same time, the stripped end of the coating may become thick and the shape may be disturbed, and it may interfere with subsequent work. Further, the stripping hole forming portions wear away with time due to contact with each other, unlike the shearing shearing type described in Patent Document 1, so that the stripping holes formed between them are separated as the wear progresses. Since it decreases in the contact direction and the cut into the coating becomes excessive, there arises a problem of cutting into the core wire relatively early. Furthermore, since the stripping direction of the coating is directed to the base side where a pair of operating levers are connected by a shaft, the operating lever pair is a grip in which the thumb and index finger of the gripping hand are directed to their free ends, The cutting force mainly depends on the pinching force between the thumb and the index finger, and it becomes difficult to work on a coating having a large cutting resistance, and the catch on the pulling side as seen in Patent Document 2 is applied to the thumb and the index finger. Even if it is provided, there is a problem that the pulling operation while maintaining the incision state is highly dependent on the pinching force between the thumb and the index finger and the thumb and index finger are easy to show off.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a coating stripper which can cut off the coating while satisfying the notch perpendicular to the axis of the coating of the cutting blade by the operating lever pair and the catch on the entire gripping hand without complication of the structure. .

  The coated stripper of the present invention is a coated stripper that removes the coating of the coated wire terminal portion to expose the core wire, and a main body in which an insertion hole for inserting the target coated wire from one end to the other end is formed, and the main body A pair of operating levers whose bases are pivotally supported on both sides of one end of the main body and the free end side extending to the other end of the main body can be opened and closed, and a stopper for restricting the most opened position of these operating levers on the main body, It is provided in the middle of the insertion hole of the main body so as to enter and exit from the operation lever side in the direction perpendicular to the axis of the insertion hole through the slit of the main body. A pair of cutting blades that leave the core wire and make cuts in the coating, and press each cutting blade against the corresponding operating lever. So as to enter and exit, it is characterized by comprising a spring biasing between the main body.

  In such a configuration, extreme bending can be corrected by inserting a covering wire into an insertion hole opened on at least one end side of the main body, and when the pair of operation levers are gripped and closed, each of the open positions is biased. The insertion holes are moved by pushing the cutting blades, which have been separated from both sides of the insertion hole by following the operating lever, to the proximity side based on a guide that allows the insertion holes of the main body to enter and exit from both sides in a direction perpendicular to the axis. The coating of the covered wire inserted into the insertion hole and corrected for extreme bending is cut without receiving unnecessary resistance in the direction perpendicular to the axis while forming a stripping hole. By this cutting, the coating can be peeled from the cutting position to the tip side of the coated wire. Therefore, by pulling the operation lever to the free end side and the front end side of the coated wire while holding it in a closed state with respect to the coated wire, the portion on the front end side of the coated wire is peeled off from the coated wire from the cut position of the coated wire. The tip of the wire can be exposed. Further, from the pulling direction of the operating lever pair with respect to such a covered wire, the operating lever pair is guided so as to be in a gripping state toward the pivoted base side where the thumb and index finger of the gripper are tapered, and the thumb and The gripping force that does not depend on the pinching force by the index finger can give a large cutting force by the cutting blade facing the middle of the operation lever pair in the longitudinal direction, and it does not depend on the pinching force by the thumb and index finger in the gripping state If necessary, the front end of the coated wire can be easily and quickly removed from the coated wire from the cut position of the coated wire by using the hook by the opening angle to the free end of the control lever pair. Can be stripped off.

  In the above, it is possible to further include a regulating means for regulating the closest position between the cutting blades to a close position where they do not contact each other.

  In such a configuration, in addition to the above, each cutting blade is regulated by the restricting means at the closest position at the time of cutting, so that a cutting depth that is not excessive or insufficient with respect to the coating is guaranteed without contacting each other. can do.

  In the above, the diameter of the stripper hole formed by each cutting blade at the closest position may be larger than the diameter of the core wire.

  In such a configuration, in addition to the above, the cutting depth can be made uniform around the core wire.

  In the above, further, the other end side of the main body is provided with a position indication that allows the difference in distance from the cutting blade to be verified through the insertion hole through the tip position of the covered wire inserted from the one end side of the main body. It can be.

  In such a configuration, in addition to the above, the tip position of the covered wire inserted into the insertion hole from one end side of the main body is aligned with a predetermined position display provided on the other end side of the main body while seeing through. Thus, the distance from the tip of the covered wire to the cutting position of the cutting blade can always be set constant in accordance with the position display.

  In the above, the see-through part may be a transparent part or a slit part of the main body.

  In such a configuration, in addition to the above, the see-through part can see the tip of the covered wire inserted into the insertion hole as the transparent part or the slit part of the main body from the outside, and the slit part is displayed as the position as it is. Can do.

  In the above, the transparent part is a transparent pipe connected to the metal part from one end of the main body to the other end side of the cutting blade, and the position indication is provided at a plurality of positions in the axial direction of the transparent pipe. Can be a feature.

    In addition to the above, in addition to connecting the transparent pipe to the metal part of the main body, the transparent part is provided on the other end side of the main body of the insertion hole, and the tip of the inserted transparent pipe is provided for the streaky display provided on the transparent part. , Including the progress of arrival, the position can be visually recognized from the outside.

  In the above description, the operation levers can be provided so as to have an opening angle between them toward the free end corresponding to the closest position of the cutting blade.

  In such a configuration, in addition to the above, the pair of operating levers opens to the free end side at the closing end position where the cutting blade is set to the closest position and a stripping hole is formed and a predetermined depth is cut into the coating. It is regulated to have a corner, and when the coating is peeled off from the distal end side of the coated wire, it is possible to catch the gripping hand holding the operating lever pair.

  In the above, the both-side operation lever may be supported on the main body by an individual shaft that is distributed from the central position of the operation lever shaft support surface of the main body to the both-side vibration operation lever side.

  In such a configuration, in addition to the above, the operating lever pair is individually pivotally supported, so that the maximum opening angle that secures the maximum separation position of the cutting blade as compared with the case where it is pivotally supported by a common shaft. Can be prevented from becoming excessive.

  In the above, it is further characterized in that at least one of the both-side operation levers is provided with a shutter that closes at least a half of the opening on the other end side of the main body of the insertion hole immediately in the final cutting operation position by the cutting blade. Can do.

  In such a configuration, in addition to the above, after cutting the covered wire into the covering to peel off the coated portion on the front end side of the coated wire, if the tapering side of the coated stripper is tilted upward, it will be peeled off. By securing the removed covering portion in the insertion hole and opening the operation lever pair, the shutter is retracted from the opening on the other end side of the main body facing below the insertion hole.

  According to the coated stripper of the present invention, the cutting blade is cut into the tip end covering of the covered wire by closing the pair of operating levers, and the operating lever pair is pulled out in the longitudinal direction toward the tip end of the covered wire to peel off the covering. In order to expose the end of the core wire, the cutting blade is cut in a direction perpendicular to the axis with respect to the coating corrected by the insertion hole, and it is cut lightly and properly without being disturbed or wasted. The stripped end of the coating is finished stably and beautifully. In addition, the control lever pair guides the gripping direction toward the base side where the thumb and forefinger taper from the pulling direction with respect to the covering wire to peel off the covering, and the gripping force that does not depend on the pinching force by the thumb and forefinger Therefore, even if it is necessary, the operation lever can be operated while maintaining the cutting state without depending on the pinching force between the thumb and the index finger. The covering can be easily and quickly peeled off to the front end side of the coated wire by utilizing the catch by the opening angle to the free end side of the pair.

  In addition to the above, each cutting blade is regulated in the closest position at the time of cutting, avoiding wear due to contact with each other, ensuring a cutting depth that is not excessive or insufficient with respect to the coating, and improving the durability of the cutting blade. While improving, it is possible to prevent unreasonable peeling without damaging the core wire.

  In addition to the above, since the stripping hole diameter formed by each cutting blade is slightly larger than the core wire diameter, the depth of cut into the coating is uniform, that is, concentric around the core wire. Also, it is possible to prevent the core wire from being scratched or made difficult to peel off.

  In addition to the above, while aligning the tip position of the covered wire inserted into the insertion hole with a predetermined position indication provided on the other end side of the main body while seeing through, until the cut position from the tip of the covered wire Since the distance can be always set constant in accordance with the position display, it is possible to prevent the stripping length of the coating from varying from time to time.

  In addition to the above, the transparent portion or the slit portion of the main body can be used as a see-through portion, and the tip of the covered wire can be seen through from the outside, and the slit portion can be omitted as a position display and a special position display can be omitted.

  In addition to the above, in addition to connecting the transparent pipe to the metal part of the main body, the transparent part is provided on the other end side of the main body of the insertion hole, and the tip of the inserted covered wire is provided for the streaky display provided on the transparent part. Since the position can be visually recognized from the outside including the progress of the alignment, the alignment work is easy and appropriate, and the number of position indications is removed to reduce the stability of the stripping length of the coating. A plurality of lengths can be selected.

  In addition to the above, the control lever pair is further regulated to have an opening angle toward the free end at the closing end position where the cutting blade is moved to the closest position and a stripping hole is formed to cut the coating into a predetermined depth. Thus, when the coating is peeled off from the front end side of the coated wire, a sufficient catching with respect to the gripping hand holding the operation lever pair is given without a special catching portion, and the ease of stripping of the coating can be ensured.

  In addition to the above, the pair of operation levers is individually supported, so that the maximum opening angle that secures the maximum separation position of the cutting blade is excessive as compared with the case where the operation lever is supported by a common shaft. It is easy to grip and close by gripping.

  In addition to the above, it is also possible to secure the stripped-off coating portion in the insertion hole by the action of the shutter that responds to the operation lever, only by stripping off the tip-side coating portion of the coated wire and considering the direction of the coating stripper. By carrying it to the position and opening the control lever pair at the predetermined position, the secured covering portion can be discarded without any problem.

  Embodiments of the coating stripper according to the present invention will be described with reference to FIGS. 1 to 3 for the understanding of the present invention. However, the following description is a specific example of the present invention and does not limit the description of the scope of claims.

  The covering stripper 100 shown in FIGS. 1 and 2 removes the covering 2 at the end of the covering wire 1 to expose the core wire 3. A main body 5 in which an insertion hole 4 for inserting a target covered wire 1 from one end to the other end is formed, and bases 6a and 6a are pivotally supported on both sides of one end of the main body 5 and extend to the other end of the main body 5. A pair of operating levers 6 and 6 that can be opened and closed on the free ends 6b and 6b side, the most open position of these operating levers 6 and 6 shown in FIGS. 1 and 2, that is, the angle β shown in FIG. A stopper 7 that is restricted on the main body 5 and a slit 9 of the main body 5 are provided in the middle of the insertion hole 4 of the main body 5 so as to enter and exit from the operation levers 6 and 6 in a direction perpendicular to the axis 11 of the insertion hole 4. The pair of cutting blades 12 and 12, each of which forms a stripping hole facing each other at the closest position, leaving the core wire 3 of the coated wire 1 and making a cut into the coating 2, and the cutting blades 12 and 12 on the corresponding side Press the operation levers 6 and 6 to So as to enter and exit from both sides into the insertion hole 4 in conjunction with the opening and closing centered on the shaft support of over 6,6, a spring 13, for urging between the main body 5.

  Thereby, the extreme bending can be corrected by inserting the covered wire 1 into the insertion hole 4 opened on at least one end side of the main body 5 in FIGS. 1 and 2, and the pair of operation levers 6 and 6 can be grasped. When the closing operation shown in the phantom line in FIG. 1 is performed, the cutting blades 12 and 12 that are separated from both sides of the insertion hole 4 by being driven by the operating levers 6 and 6 at the opening position by urging are moved to the main body 5. 2 is formed between the meniscus blades 12b by pushing into the insertion side and entering the insertion hole based on a guide that allows the insertion hole to enter and exit from both sides in a direction perpendicular to the axis of the insertion hole. In this manner, the sheath 2 of the sheathed wire 1 inserted into the insertion hole 4 and whose extreme bending is corrected is cut in a direction perpendicular to the axis 11 without receiving unnecessary resistance. By this cutting, the covering 2 is in a state where it can be peeled off from the cutting position to the tip side of the covering wire 1.

  Accordingly, the operating levers 6 and 6 are held in a closed state with respect to the covered wire 1 and pulled out in the direction of arrow A shown in FIG. 1 is peeled off from the covered wire 1 and the tip of the covered wire 1 is exposed at a length L.

  As a result, the cutting blades 12 and 12 are cut into the tip end covering 2 of the covered wire 1 by closing the pair of operating levers 6 and 6, and the pair of operating levers 6 and 6 are extended in the longitudinal direction of the tip of the covered wire 1. The cutting blades 12, 12 are coated with an extreme bend corrected by the insertion hole 4, so that the end 2 of the core wire 3 is exposed at the length L. 2 is cut in a direction perpendicular to the axis 11, and is appropriately cut lightly and appropriately without being disturbed or wasteful resistance, and the stripped end of the coating 2 is stably and beautifully finished.

  Further, from the pulling direction of the operation levers 6 and 6 pairs with respect to the coated wire 1, the operation levers 6 and 6 are gripped toward the pivoted bases 6a and 6a where the thumb and index finger of the gripper are tapered. The gripping force that does not depend on the pinching force between the thumb and the index finger can give a large cutting force by the cutting blades 12 and 12 facing the middle of the operation levers 6 and 6 in the longitudinal direction. In addition, the opening angle shown in FIG. 1 toward the free ends 6b and 6b of the pair of operating levers 6 and 6 if necessary while maintaining the incision state without depending on the pinching force between the thumb and the index finger in the grip state. The portion 2a having a length L on the front end side of the covered wire 1 can be easily and quickly peeled off from the covered wire 1 from the cutting position of the covered 2 by using the catch by α.

  As a result, the control levers 6 and 6 are guided by the gripping direction toward the bases 6a and 6a where the thumb and the index finger are tapered from the pulling direction with respect to the coating wire 1 for stripping the coating 2, and are sandwiched between the thumb and the index finger. Since the gripping force that does not depend on the force becomes a large cutting force by the cutting blade, the coating 2 having a high cutting resistance can be easily and instantaneously cut, and the cutting state is not dependent on the pinching force between the thumb and forefinger. If necessary, it is possible to easily peel off the covering 2 to the front end side of the covered wire 1 by using the catch by the opening angle α to the free ends 6b and 6b of the pair of operating levers 6 and 6 if necessary. Can be done quickly.

  Here, the main body 5 has a quadrangular cross section as shown in FIG. 2 and is easily opened and closed by pivotally supporting a pair of operating levers 6 and 6 on both side surfaces thereof. The same guide width is secured so that the guide can be stably guided, and the insertion hole 4 has a circular cross section similar to that of the covered wire 1 so that it can be positioned by uniform play in any direction around the axis 11. is there. The spring 13 acting on the cutting blades 12, 12 is disposed in the window 12 c of the cutting blades 12, 12, and the recess 5 a formed on the surface corresponding to the operation levers 6, 6 of the main body 5 and the cutting blades 12, 12. Each of the windows 12c and 12c is positioned and operated with respect to the projection 12d provided on the window edge on the operation lever 6 and 6 side of the windows 12c and 12c so as not to be displaced or dropped out. Further, the springs 13 and 13 work so as to avoid contact with the operation levers 6 and 6 as a conical coil spring having a diameter that decreases from the main body 5 to the operation levers 6 and 6.

  Each of the cutting blades 12 and 12 is provided with a restricting means 14 for restricting the closest position where they form the stripping hole 12a to a close position where the gap S shown in phantom lines in FIG. It is. For this reason, the cutting blades 12 and 12 are regulated by the restricting means 14 at the closest position at the time of cutting, so that wear due to contact with each other is avoided and a cutting depth with respect to the covering 2 is ensured. It is possible to improve the durability of the cutting blades 12 and 12 without undue damage to the core wire 3 without damaging the core wire 3. The restriction of the closest position of the cutting blades 12 and 12 is that the operation levers 6 and 6 cannot be operated beyond that, and the closest position of the operation levers 6 and 6 or the minimum opening angle α is restricted. I mean.

  The operation levers 6 and 6 pairs are parallel to each other or do not taper toward the free ends 6b and 6b, and by securing such a minimum opening angle α, the cutting blades 12 and 12 cut into the coating 2 after the cutting. Thus, it is possible to secure a catch on the hand grip during the pull-out operation. Therefore, it is not necessary to provide a special catch structure. However, a catching portion such as a non-slip or protrusion such as irregularities may be provided as necessary.

  The regulating means 14 may be formed in any way, but in the present embodiment, as shown in FIGS. 2 and 3, the slits opened on both side surfaces of the main body 5 on which the operation levers 6 and 6 are pivotally supported. Both side plates 16 and 16 are formed as regulating members integrated with the main body 5 by screwing them with a countersunk screw 15 so as to close 9. The side plates 16 are formed so as to correspond to the slits 9 of the main body 5 and to extend the slits 12 or 12 for receiving the slits or grooves 16a for receiving the side edges. Then, the cutting edges 12 and 12 are received at the close position where the gap S is left at the lower end of the receiving portion 16a to restrict the closest position. Further, the side plates 16 and 16 project toward the operation levers 6 and 6 side of the main body 5 to enlarge the guide area for the cutting blades 12 and 12 so that the cutting blades 12 and 12 are smoothly separated and connected. It can be operated.

  Further, the diameter of the stripper hole 12a formed by each of the cutting blades 12 and 12 at the closest position regulated in this way is larger than the diameter of the core wire 3 as shown by an imaginary line in FIG. Slightly larger and the cutting depth is uniform around the core wire 3, that is, concentric, thus preventing the core wire 3 from being scratched at the peripheral portion in the circumferential direction and preventing the coating 2 from forming a portion that is difficult to peel off. be able to.

  Further, on the other end side of the main body 5, a position indication that allows the difference in the distance L from the cutting blades 12, 12 to be verified by seeing through the distal end position of the covered wire 1 inserted from the one end side of the main body 5 into the insertion hole 4. 21 is provided. Thereby, by aligning the tip position of the covered wire 1 inserted into the insertion hole 4 from one end side of the main body 5 with a predetermined position indication provided on the other end side of the main body 5, the covered wire 1 Since the distance L from the tip of 1 to the cutting position of the cutting blade is always set in accordance with the position display 21, it is possible to prevent the stripping length L of the coating 2 from varying from time to time. it can.

  Such a see-through part is a transparent part or slit part of the main body 5, and the tip of the covered wire 1 inserted into the insertion hole 4 can be seen through from the outside, and the slit part can be used as the position display 21 as it is. In the embodiment, a transparent portion is adopted and formed by a transparent pipe 53 connected to a metal portion extending from one end of the book 5 to the other end side of the cutting blade, and the position indication 21 is in the direction of the axis 11 of the transparent pipe 22. It is provided in a plurality of places, specifically three places, in the circumferential direction. Specifically, it is provided on the entire circumference of the transparent pipe 53 and is formed by a recess. As a result, by simply connecting the transparent pipe 53 to the metal portion of the main body 5, the transparent portion is provided on the other end side of the main body of the insertion hole 4, and the inserted transparent pipe 53 has a streak-like position provided at the transparent portion. The display 21 is visually recognized from the outside including the progress of the covered wire 1 and is aligned so that the alignment work can be performed easily and appropriately, and the stability of the stripping length L of the coating 2 is not impaired. Further, a plurality of stripping lengths L can be selected as many as the number of position indications.

  As shown in FIGS. 1 and 3, the metal portion to which the transparent pipe 53 of the main body 5 is connected is formed by a metal block 51 on one end side of the main body 5 and a metal block 52 on the other end side. The metal blocks 51 and 52 are integrally connected by using the caulking of the side plates 16 and 16 to the main body 5 at four places so that the gaps 52 form the slits 9. However, both the metal blocks 51 and 52 are integrally formed, and the slit 9 can be cut into the single metal block or continuous with the receiving portions 16a and 16a located on both sides of the slit 9.

  Further, the both-side operation levers 6 and 6 are individually arranged from the center position of the operation lever shaft support surface of the main body 5 to the both-side vibration operation levers 6 and 6 side as shown in FIGS. The main body 5 is pivotally supported by rivets 41 and 41 as shafts. As described above, the operation levers 6 and 6 are individually pivotally supported, so that the maximum opening angle β that secures the maximum separation position of the cutting blades 12 and 12 can be obtained as compared with the case where the operation levers 6 and 6 are pivotally supported. Since it can suppress that it becomes excessive, it is easy to hold and the closing operation by grip becomes easy.

  Here, the stopper 7 is provided between the base portions 6a, 6a of the both operation levers 6, 6 by using the fact that the both operation levers 6, 6 are individually supported. The levers 6 and 6 are operated. Specifically, a screw 42 screwed and fixed slightly between the shaft support positions of the operation lever shaft support surface of the main body 5 by the rivet 41 and slightly closer to one end side of the main body 5 is provided. 6, the two side operation levers 6 and 6 are positioned between the bases 6a and 6a so as to be received at a symmetrical opening position with the axis 11 having the maximum opening angle β as a boundary.

  Finally, a shutter 43 as shown in FIG. 1 is welded to one of the two operating levers 6 and 6, and both the operating levers 6 and 6 place the cutting blades 12 and 12 on the cover 2. When the minimum opening angle α to be fixed is cut, as shown in FIG. 1, the opening 53a of the transparent pipe 53 is positioned so as to close at least half of the opening 53a. Thus, after the cutting operation of the covering wire 1 into the covering 2 is performed and the tip side covering portion 2a of the covering wire 1 is peeled off, when the tapering side of the covering stripper 100 is inclined upward, the stripped covering portion is peeled off. 2a is secured in the insertion hole 4, and the shutter 43 is retracted from the opening 4a on the other end side of the main body 4 which faces the lower side of the insertion hole 4 by opening the operation levers 6 and 6 pairs. 2a can be discarded. Therefore, the covering portion 2a peeled off by the action of the shutter 43 that responds to the operation lever 6 can be put into the insertion hole 4 only by peeling off the tip side covering portion 2a of the covering wire 1 and considering the direction of the covering stripper 100. By securing and carrying it to a predetermined position and opening the pair of operating levers 6 and 6 at the predetermined position, the secured covering portion 2a can be discarded without any problem. Further, as shown in FIG. 1, the metal part 52 and the transparent pipe 53 are connected by fitting the transparent pipe 53 into the concave part 52 a of the metal part 52 and fixing with the screw 61. However, any connection structure or fixed structure may be used.

  The present invention has a simple structure, obtains a beautiful peeled-off end by cutting perpendicular to the axis of the cutting blade cover, and is easy to be satisfied with the catch on the entire grip of the operating lever on both sides without complicating the structure. And the coating can be removed quickly.
