Description

  The present invention relates to a gardening hair clipper, for example, a hand-held garden hair clipper that can be used by exchanging two kinds of blade assemblies as necessary when cutting a lawn, a hedge, or the like.

  Patent Document 1 discloses a gardening hair clipper. The horticultural hair clipper includes a hedge blade assembly, a lawn blade assembly, and a body to which one of these two types of blade assemblies can be attached. When trimming various standing trees, hedges and other outdoor plants, the user attaches the blade blade assembly to the main body and uses the clippers as hedge clippers. When mowing the lawn, the user attaches the blade assembly to the body and uses the clipper as a lawn clipper.

  The hedge clipper is preferably provided with a structure for preventing the user's hand from being injured by the hedge. For example, according to the Chinese national compulsory standard << Handheld Power Tools Safety Part 2: Special Pruning Request >> (GB3883.15-2007), the distance from the cutter blade to the grip should not be less than 120 mm. It is requested. If it is less than 120 mm, a guard plate (chip guard described later) must be provided between the grip and the cutter blade. When the distance from the cutter blade to the grip is maintained at 120 mm or more, the clipper becomes large. As a result, the hand-held hair clipper may not meet the requirements for downsizing. Therefore, a tip guard is usually attached to the main body of the hedge clipper on the side where the blade assembly is located. Moreover, in order to ensure safety, the chip guard is usually attached to the main body with bolts or the like.

  On the other hand, there is no such requirement for lawn hair clippers. However, lawn hair clippers can break the blade or damage the wall or other obstacles when the tip of the blade assembly hits the wall or other obstacles. In order to avoid such a situation, it is desired that the blade protector be installed in the vicinity of the blade assembly in the body of the lawn clipper.

  Therefore, when using the gardening hair clipper of Patent Document 1, the following operation must be performed. That is, when using a garden clipper as a hedge clipper, the hedge blade assembly must be attached to the main body, and the tip guard must be attached to the main body with a tool such as a screwdriver. When using a garden clipper as a lawn clipper, replace the hedge blade assembly with a lawn blade assembly. In this case, it is necessary to remove the tip guard from the main body with a tool such as a screwdriver and attach the protector to the main body.

Chinese Utility Model No. 2010182668 Specification

  As described above, when the horticultural clippers are used by switching between the hedge clippers and the lawn clippers, the tip guard and the blade protector must be attached and detached by complicated work, which is inconvenient for the user. Moreover, the replaced chip guard or blade protector must be accommodated, increasing the burden of storage, and parts such as bolts are easily lost. If the blade guard is attached to the main body and the tip guard or the blade protector is exchanged for the main body, there is a risk that safety concerns may increase. Therefore, there has been a need for a gardening hair clipper that is convenient and safe to use.

  In one aspect, the horticultural hair clipper of the present invention includes a main body that houses a prime mover, a blade assembly that extends forward from the front surface of the main body, and a grip that is disposed on the main body and is gripped by a user. The grip includes a front grip disposed on the front portion of the main body and a rear grip disposed on the rear side of the front grip. Alternatively, the grip includes a rear grip and does not include a front grip. The blade assembly includes two blades in which at least one blade can reciprocate, and is driven so that at least one blade reciprocates in a prime mover. If the grip includes a front grip and a rear grip, a tip guard is located between the front grip and the blade assembly. If the grip includes a rear grip and does not include a front grip, a tip guard is located between the body and the blade assembly. A blade protector is disposed on the main body or the tip guard. The blade protector covers at least a portion of the blade assembly in a plan view projection.

  Therefore, the tip guard and the blade protector can be provided at the same time on the clipper. The blade protector is directly attached to the main body without removing the tip guard. Thus, the blade protector can be removed with a simple operation. In addition, safety can be enhanced by providing a tip guard and a blade protector at the same time.

  In other features, the blade assembly includes a first type of blade assembly in which at least one blade reciprocates in the longitudinal direction of the body, and a second type in which at least one blade reciprocates in the width direction perpendicular to the longitudinal direction of the body. A seed blade assembly. A first type blade assembly and a second type blade assembly are interchangeably attached to the body.

  Therefore, by attaching the first type blade assembly to the main body, the clipper can be used as a hedge clipper, for example. By attaching the second type blade assembly to the main body, the clipper can be used as a lawn clipper, for example.

  In another feature, when the second type blade assembly is attached to the main body, the front end of the blade protector is positioned in front of the front end of the second type blade assembly in a plan view. Therefore, the blade protector can hit the wall or the like before the second type blade assembly. Therefore, damage to the front end of the blade or damage to the object caused by the second type blade assembly hitting the object such as a wall can be prevented.

  In another feature, the blade protector is a member independent of the main body and the tip guard, and is detachably attached to the main body or the tip guard. Therefore, a blade protector can be used as needed. For example, when the blade assembly is used as a lawn blade assembly, the blade protector is attached to the main body or the tip guard. This prevents damage to the blade or walls, etc. by the blade protector. When using the blade assembly as a hedge blade assembly, the blade protector is removed from the main body or the tip guard. Thereby, it is possible to prevent the effective length of the blade from being shortened by the blade protector.

  In another feature, the blade protector includes a plate-shaped protection plate having a through-hole at the center. The blade protector is disposed on the main body with the tip guard penetrating the penetrating portion. Therefore, the blade protector is disposed on the main body so as not to interfere with the tip guard. The blade protector is disposed on the main body and is held by the main body. Therefore, the force received by the blade protector can be held by the main body.

  In other features, the blade protector has a locking portion and the body has a locking groove engageable with the locking portion. By sliding the locking portion along the locking groove, the locking portion and the locking groove are engaged, and the blade protector is attached to the main body. Therefore, the blade protector can be easily and reliably attached to the main body.

  In other features, locking grooves are formed on both sides of the body. The blade protector has two locking portions that engage with the locking grooves and a gripping portion that protrudes from the upper surface of the protection plate. The blade protector is deformed so as to increase the distance between the two locking portions by applying a force to the gripping portion. Therefore, for example, when the user applies a force to the gripping portion with one hand, the space between the two locking portions is widened. Thereby, a blade protector can be easily attached or detached with respect to a main body.

  In another feature, the blade protector includes a plate-shaped protection plate and a locking portion. Locked portions that engage with the locking portions are provided on both sides of the chip guard or both sides of the main body. Therefore, the blade protector can be easily and reliably attached to the tip guard or the main body.

  In other features, the blade protector constitutes a blade protection cover for the second type of blade assembly. Therefore, the blade protector can also be used as a blade protect cover, and the number of parts can be saved.

  In other features, a reinforcing rib is provided at the front end of the blade protector. Therefore, the strength of the blade protector can be ensured. For this reason, the blade protector can withstand the external force received during trimming when used as a blade protection cover.

  In other features, the horticultural hair clipper has a body that houses a prime mover, a blade assembly, a tip guard, and a blade protector. The blade assembly includes two blades that extend from the front surface of the main body to the front side and that reciprocate relatively by the output of the prime mover. The tip guard extends from the main body and shields between the front surface of the main body and the blade assembly. The blade protector is detachably attached to the main body or the tip guard, and covers at least a part of the blade assembly in front or side of the tip guard in a plan view projection. For example, the width of the blade protector is wider than the tip guard and wider than or substantially the same as the width of the blade assembly. Thus, the blade protector covers at least a part of the blade assembly on the side of the tip guard.

  First, main features of the embodiment are listed. The clipper of this embodiment includes two types of blade assemblies. The first type of blade assembly is a hedge blade assembly mainly used for cutting a hedge. The second type of blade assembly is a lawn blade assembly mainly used for mowing grass. The hedge blade assembly can be used not only for cutting hedges but also for cutting various standing trees, shrubs and other outdoor plants. The lawn blade assembly can be used not only for cutting the lawn but also for cutting other flowers.

  The clipper of the present embodiment further includes two types of safety protectors. One type is a tip guard that is always attached to the front of the main body and prevents the user's hand from being injured by a hedge or the like. The other type is a blade protector, which is attached to the front part of the body or the tip guard. The blade protector prevents the blade from hitting and damaging hard objects such as walls, flower beds and pipes when the second type blade assembly (lawn blade assembly) is attached to the clipper and the clipper is used. Prevents damage to wooden walls, hoses, etc.

  A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an exploded view of a clipper 10 to which a hedge blade assembly 100 (first type blade assembly) is attached. FIG. 2 is an exploded view of the clipper 10 to which the lawn blade assembly 200 (second type blade assembly) is attached.

  The hair clipper 10 includes a main body 12 shown in FIGS. 1 and 2, a hedge blade assembly 100 shown in FIG. 1, and a lawn blade assembly 200 shown in FIG. In the clipper 10, the blade assemblies 100 and 200 can be replaced according to work. The hedge blade assembly 100 can be used when cutting a hedge. The lawn blade assembly 200 can be used when mowing the lawn. The clipper 10 further includes a grass collector 17 (see FIG. 4) shown in FIG. 4 as an accessory.

  In this specification, for the sake of convenience, the longitudinal direction of the clippers is defined as the front-rear direction, and the width direction of the clippers is defined as the left-right direction. The side where the blade assembly extends from the main body is the front side, the opposite side of the front side is the rear side, the side where the blade assembly of the main body is located is the lower side, and the side where the main body is located is the upper side.

  The blade assemblies 100 and 200 will be described with reference to FIGS. As shown in FIG. 1, the hedge blade assembly 100 includes a pair of shear blades 110, a first lower plate 120 and an upper plate 130 for holding the pair of shear blades 110. The pair of shear blades 110 are sandwiched between the first lower plate 120 and the upper plate 130 and are slidably supported. Each shear blade 110 is formed with cutting edges 112 arranged in a comb shape along the sliding direction. The pair of shear blades 110 cut the hedge branches and leaves with the cutting edges 112 as they reciprocate relatively.

  As shown in FIG. 2, the lawn blade assembly 200 includes a pair of shear blades 210, a second lower plate 220 that holds the pair of shear blades 210, and support pins 230. The pair of shear blades 210 are fixed to the second lower plate 120 by the support pins 230 and supported so as to be swingable. Each shear blade 210 is formed with a cutting edge 212 arranged in a comb shape along the swing direction. The pair of shear blades 210 mow the lawn with their cutting edges 212 as they reciprocate relatively.

  Each blade assembly 100, 200 is attached to the main body 12 by the pressing force of the screw member or the bottom cover 30.

  Next, the main body 12 will be described with reference to FIGS. As shown in FIGS. 1 and 2, the main body 12 includes a housing 14 and a bottom cover 30. The housing 14 has a trigger 16 as a start switch, a rear grip 18 and a front grip 19 for gripping by the user, a battery case 20 as a power source, and prevents the user's hand from being injured by the hedge when trimming the hedge. A tip guard 300 is provided, and a blade protector 500 (see FIG. 4) is provided to prevent damage to blades, walls, etc. when mowing the lawn. The rear grip 18 and the front grip 19 each constitute a grip. The main body 12 may or may not include the front grip 19. When the front grip 19 is not provided, the grip is constituted only by the rear grip 18.

  An opening 24 for attaching the blade assemblies 100 and 200 is provided at the bottom of the housing 14. One of the hedge blade assembly 100 and the lawn blade assembly 200 is mounted in the opening 24 of the housing 14. After attaching any one of the blade assemblies 100, 200, the bottom cover 30 is attached to the opening 24 of the housing 14. The hedge blade assembly 100 is fastened to the housing 14 by fixing bolts 140 before the bottom cover 30 is attached.

  Next, the internal structure of the main body 12 and the operation process of the clipper 10 will be described with reference to FIG. FIG. 3 shows the clipper 10 with the hedge blade assembly 100 attached thereto. The structure of the main body 12 when the lawn blade assembly 200 is attached is the same as the structure of the main body 12 when the hedge blade assembly 100 is attached. Therefore, illustration and description thereof are omitted.

  As shown in FIG. 3, the main body 12 includes a motor 40 as a motor of the clipper 10, a motor pinion 42 provided in the motor 40, a two-stage gear 44 that meshes with the motor pinion 42, and a final gear 50 that meshes with the two-stage gear 44. Prepare. A recess 52 is formed on the lower end surface of the final gear 50, and a part of the cam member 60 (see FIG. 2) is accommodated in the recess 52.

  The motor 40 is electrically connected to the battery case 20 via the trigger 16. When the user operates the trigger 16, the motor 40 is rotated by the electric power supplied from the battery case 20. When the motor 40 rotates, the final gear 50 rotates via the motor pinion 42 and the two-stage gear 44. The final gear 50 is supported by the shaft 70 and rotates around the shaft 70. The final gear 50 is a rotating member that is driven and rotated by the motor 40.

  A cam member 60 is fixed to the lower end surface of the final gear 50 so as not to rotate with respect to the final gear 50. The cam member 60 is fixed coaxially with the final gear 50 and rotates around the shaft 70 together with the final gear 50. Therefore, the cam member 60 is driven and rotated by the motor 40 together with the final gear 50. As shown in FIG. 1, two connecting pins 54 are provided on the lower end surface of the final gear 50 (not shown in FIG. 3). The connecting pin 54 holds the cam member 60 so as not to rotate with respect to the final gear 50. The cam member 60 is detachable from the final gear 50, and is removed from the final gear 50 by removing the blade assemblies 100 and 200 from the main body 12.

  By attaching the blade assemblies 100, 200 to the main body 12, the pair of shear blades 110, 210 of the blade assemblies 100, 200 are connected to the cam member 60. As the cam member 60 rotates, the pair of shear blades 110 and 210 reciprocate in conjunction with the cam member 60. The pair of shear blades 110 and 210 reciprocate between each other with a phase difference of 180 degrees. When the hedge blade assembly 100 is attached to the main body 12, the cam member 60 is attached to the main body 12 such that the first surface faces the final gear 50. When the lawn blade assembly 200 is attached to the main body 12, the cam member 60 is attached to the main body 12 so that the second surface, which is the back surface of the first surface, faces the final gear 50.

  The chip guard 300 and the blade protector 500 will be described in detail with reference to FIGS. FIG. 4 is a perspective view in the middle of assembling the clipper of the first embodiment to which the grass blade assembly is attached. FIG. 5 is a perspective view of the blade protector in the first embodiment. FIG. 6 is a side view in the middle of assembling the clipper of the first embodiment to which the grass blade assembly is attached. FIG. 7 is a plan view in the middle of assembling the clipper of the first embodiment to which the grass blade assembly is attached.

  A structure for attaching the tip guard 300 and the blade protector 500 to the housing 14 will be described below. As shown in FIG. 4, an extension port 13 is provided between the lower end of the front surface of the housing 14 and the bottom cover 30 (see FIG. 2). When the blade assemblies 100 and 200 are attached to the main body 12, the blade assemblies 100 and 200 extend forward from the extension port 13 of the main body 12. Therefore, the hedge or lawn can be trimmed by the blade assemblies 100 and 200. A tip guard attaching portion 15 is provided at a front portion of the main body 12 slightly above the extension port 13. The tip guard mounting portion 15 is provided along the lower end of the front surface of the housing 14.

  The housing 14 is provided with a pair of locking grooves 191 for mounting the blade protector slightly above the tip guard mounting portion 15. The pair of locking grooves (locked portions) 191 are provided symmetrically on the left and right sides of the front portion of the housing 14. The pair of locking grooves 191 extends obliquely rearward and downward from the front side of the housing 14. In each of the pair of locking grooves 191, a recessed groove portion 193 that is further depressed is provided.

  Next, a specific structure of the chip guard 300 will be described. The chip guard 300 is made of a hard resin, and is formed by resin molding or the like, and the material and manufacturing method thereof are not particularly limited as long as the chip guard 300 acts so as to block a hedge or the like. The chip guard 300 includes a fixing portion 310 for fixing to the main body 12 and a shield plate 320 for blocking the hedge. The fixing portion 310 is provided with a screw hole portion through which the bolt 340 shown in FIG. The chip guard mounting portion 15 of the housing 14 is also provided with a through hole portion corresponding to the screw hole portion of the fixing portion 310. The fixing part 310 is fixed to the chip guard attaching part 15 by screwing the bolt 340 into the screw hole part of the fixing part 310 and the through hole part of the housing 14.

  As shown in FIG. 4, the shield plate 320 integrally extends obliquely upward from the fixed portion 310 toward the blade side. The shield plate 320 preferably has a plate shape that is smoothly recessed toward the side with the blade. Needless to say, the shield plate 320 is not particularly limited in its specific shape as long as it acts so as to block a hedge or the like. Moreover, as long as the shield plate 320 can firmly fix the chip guard 300 to the housing 14, the specific attachment method is not limited to the attachment using the screw member. The tip guard 300 is disposed at a position above the blade assembly 200 on the front surface of the main body 12. The tip guard 300 extends from the front surface of the main body 12 and shields between the front surface of the main body 12 and the blade assembly 200.

  Next, a specific structure of the blade protector 500 will be described. As shown in FIGS. 4 to 7, the blade protector 500 is attached to the clipper 10 to which the lawn blade assembly 200 is attached. The material and manufacturing method of the blade protector 500 are not limited, and the same material as the tip guard 300 can be employed.

  The blade protector 500 includes a protective plate 550 that protects and a pair of leg portions 511 for attachment to the main body 12 as shown in FIG. The protection plate 550 has a fan plate shape, and a through portion 520 having a size capable of penetrating the chip guard 300 is provided at the center of the protection plate 550. 6 and 7, when the blade protector 500 is attached to the main body 12, the protection plate 550 is substantially parallel to the extending plane of the blade assembly 200. The protection plate 550 covers a part of the blade assembly 200 in the projected state, and the front end of the blade protector 500 is located in front of the blade assembly 200. The both side ends of the blade protector 500 are the same as the both side ends of the blade assembly 200 or are located outside the both side ends of the blade assembly 200.

  The protection plate 550 does not necessarily have to be substantially parallel to the plane in which the blade assembly 200 extends, and may be oblique with an angle in the extending direction of the blade assembly 200. The blade protector 500 may be positioned outside the blade assembly 200 in only one direction, that is, forward, backward, left, and right. This can prevent blade or wall damage in at least one direction.

  The protection plate 550 is provided with a reinforcing portion (reinforcing rib) 560 along the front edge, and the strength of the blade protector 500 is increased by the reinforcing portion 560. A pair of gripping parts 531 for attaching / detaching the blade protector 500 is provided at the rear part of the protective plate 550. The pair of gripping portions 531 are apart from each other by a certain distance, and each have a rib shape protruding upward from the surface of the protective plate 550. The pair of gripping portions 531 are arranged side by side in the width direction of the clipper 10, but are not limited to this, and the specific shape is not limited as long as the effects described below can be realized. For example, the gripping portion may be a single U-shaped protrusion when viewed from the front. Or the some protrusion form etc. which were intermittently arranged in the longitudinal direction of the clipper 10 may be sufficient.

  Each of the pair of leg portions 511 extends obliquely downward from the rear end of the protection plate 550. Protruding portions (locking portions) 513 that match the recessed groove portions 193 of the locking grooves 191 are provided on the opposing inner portions of the pair of leg portions 511. The distance between the pair of leg portions 511 matches the distance between the locking grooves 191 located on both sides of the housing 14.

  Next, a procedure for the user to attach the blade protector 500 to the main body 12 will be described. When the user attaches the blade protector 500 to the main body 12, a force is applied from the outside to the pair of gripping parts 531 with the thumb and forefinger in such a direction that the distance between the pair of gripping parts 531 decreases. At this time, elastic deformation occurs between the pair of gripping portions 531 and the leg portions 511 open outward. While maintaining this state, the user moves the blade protector 500 from above to below. As a result, the tip guard 300 penetrates through the penetrating portion 520 of the blade protector 500 from the bottom to the top. At the same time, the blade protector 500 is moved from the front to the rear, and the leg portion 511 is slid along the locking groove 191. When the front end of the leg portion 511 reaches the end of the locking groove 191, the force applied to the grip portion 531 is relaxed. As a result, the protruding portion 513 of the leg portion 511 and the recessed groove portion 193 in the locking groove 191 are engaged with each other. Thus, the blade protector 500 can be easily attached to the main body 12.

  When it is desired to remove the blade protector 500 from the main body 12, a force is applied from the outside to the pair of gripping parts 531 with the thumb and forefinger in such a direction that the distance between the pair of gripping parts 531 decreases. At this time, elastic deformation occurs between the pair of gripping portions 531 and the leg portions 511 open outward. As a result, the engagement between the protruding portion 513 of the leg portion 511 and the recessed groove portion 193 in the locking groove 191 is released. While maintaining this state, the user moves the blade protector 500 from below to above. As a result, the tip guard 300 is detached downward from above with respect to the penetrating portion 520 of the blade protector 500. At the same time, the leg protector 511 slides along the locking groove 191 by moving the blade protector 500 from the rear to the front. After the leg portion 511 is completely detached from the locking groove 191, the force applied to the grip portion 531 is loosened. Thus, the blade protector 500 is easily removed from the main body 12.

  The penetrating portion 520 of the protective plate 550 can be set as large as possible within a range in which the strength necessary for the protective plate 550 is ensured. By enlarging the penetration part 520, the protection plate 550 is easily deformed, and the protection plate 550 is easily attached to and detached from the main body 12. Moreover, the protective plate 550 can be reduced in weight.

  In the first embodiment, the user can directly attach the blade protector 500 to the main body 12 without removing the tip guard 300 when using the clipper 10 as a lawn clipper. Therefore, the parts replacement work necessary for changing the application of the clipper 10 is simplified, and safety in each application is sufficiently obtained. In addition, the user can attach / detach the blade protector 500 to / from the main body 12 with one hand. Therefore, parts replacement can be simplified.

  According to the clipper 10 of this embodiment, it is not necessary to remove the chip guard 300 when cutting the lawn or hedge. By adding the blade protector 500 when mowing the lawn, the lawn mowing work can be performed more safely. Therefore, the clipper 10 can be used conveniently and has a simple structure. Moreover, it is safe, and it is possible to achieve the effects of eliminating the addition of screws and losing parts and reducing the fear of safety.

  The first embodiment has been described above. However, the first embodiment is not limited to the above description, and various modifications can be made.

  As a modification, the blade protector 500 is provided with only one leg portion. One locking groove extending downward is provided in the front portion of the main body 12. The blade protector 500 is attached to the main body 12 only by engagement of one leg portion and one locking groove.

  The blade protector 500 has a fan-shaped plate protection plate 550 and a through portion 520 formed in the protection plate 550. The size and shape of the penetrating part 520 can be set such that the outer peripheral edge of the penetrating part 520 engages with the outer end of the chip guard 300. Alternatively, the tip guard 300 is configured not to interfere with the blade protector 500 when the blade protector 500 is attached to the main body 12. The size and shape of the blade protector 500 can be freely changed as long as these configurations can be achieved.

  Subsequently, a second embodiment will be described. The difference between the second embodiment and the first embodiment is that the blade protector 600 is directly attached to the tip guard 300 instead of the blade protector 500 being attached to the main body 12. Other structures are the same as those of the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 8-10, the blade protector 600 includes a U-shaped plate protection plate 630 and a leg portion 611 extending as if bent from both ends of the protection plate 630. The leg portion 611 is attached to the tip guard 300, and the protective plate 630 provides a protective action.

  The protection plate 630 is a plate shape curved in a two-dimensional plane, and the curve is smoothly recessed in a direction away from the main body 12 (front). The protective plate 630 follows the outline of the front end of the clipper 10 along the width direction of the clipper 10. A reinforcing portion (reinforcing rib) 660 is formed at the end (front end) of the protective plate 630 far from the main body 12 along the end.

  When the protection plate 630 is attached to the chip guard 300, the entire protection plate 630 is positioned on the front side of the chip guard 300. The protection plate 630 is substantially parallel to the extending plane of the blade assembly 200, and the front end of the blade protector 600 is located in front of the front end of the blade assembly 200. The both side ends of the blade protector 600 are the same as the both side ends of the blade assembly 200 or are located outside the both side ends of the blade assembly 200.

  The pair of leg portions 611 extends rearward and downward from both end portions of the protective plate 630 in the clipper width direction. An insertion groove 621 is provided in each of the opposed inner portions of the leg portion 611. Insert strips 321 that can be engaged with the insertion groove 621 are provided on both side edges (both sides) of the chip guard 300 corresponding to the insertion groove 621. The connection method between the leg portion 611 and the chip guard 300 is not limited to the connection method between the insertion groove 621 and the insertion strip 321, as long as the leg portion 611 and the chip guard 300 are engaged with each other. The leg portion 611 of the blade protector 600 and the insertion strip 321 of the tip guard 300 constitute a locking portion and a locked portion.

  When the blade protector 600 is attached to the chip guard 300, the pair of insertion grooves 621 of the blade protector 600 are aligned with the pair of insertion strips 321. Thereafter, the blade protector 600 is moved downward, and both ends of the blade protector 600 are inserted into both sides of the chip guard 300. When removing the blade protector 600, an upward external force is applied to the blade protector 600 to remove the blade protector 600 from the tip guard 300.

  As a modification, insertion strips that engage with the insertion grooves of the leg portions of the blade protector can be provided on both side portions of the main body 12 instead of the tip guard. Therefore, the blade protector can be attached to the main body 12 by the engagement between the insertion groove and the insertion strip.

  When the second embodiment is adopted, it is not necessary to process the locking groove in the main body 12 in addition to providing the effects provided by the first embodiment. Therefore, the structure of the main body 12 is simplified, and the cost can be reduced. It is also possible to reduce the weight.

  The first embodiment and the second embodiment have been described in detail above. Needless to say, however, those skilled in the art can make modifications based on the above disclosure.

  For example, the blade protector 600 may be configured as a blade protect cover for the blade assembly 200. That is, the blade protector 600 and the blade assembly 200 may be configured as a single member. Thus, by sharing the blade protect cover and the blade protector, the structure can be simplified and the loss of parts can be prevented.

  In the first embodiment and the second embodiment, the blade protector 500 and the blade protector 600 are detachably attached to the main body 12 or the tip guard 300. Instead of this configuration, the blade protector 500 and the blade protector 600 may be formed integrally with the main body 12 or the chip guard 300. The blade protector 500 and the blade protector 600 are provided on the body of the clipper so as not to interfere with the blade assembly. Therefore, when replacing the blade assembly, there is no need to remove the blade protector and the tip guard from the main body.

  As a power source, an external power source may be used. In this case, a power line is provided at the rear of the main body, the power line is connected to the commercial power network, and power from the commercial power network can be supplied to the clippers.

  What has been described above are merely preferred specific embodiments of the present invention. Therefore, the protection scope of the present invention is not limited to this, and includes those in which those skilled in the art can easily conceive changes or substitutions within the technical scope disclosed in the present invention.

  INDUSTRIAL APPLICABILITY The present invention can be used for a hand-held clipper that can be used by exchanging two kinds of blade assemblies as necessary when cutting a lawn, a hedge, or the like.
