Description

Technical Field

[0001] This application belongs to the field of garden tool technology, specifically relating to a hedge trimmer. Background Technology

[0002] A hedge trimmer is a gardening power tool specifically designed for pruning and shaping hedges and shrubs. It uses an electric motor or gasoline engine to drive a set of sharp blades in a high-speed reciprocating motion, replacing traditional hand shears and significantly improving pruning efficiency and uniformity. Users can easily cut branches and leaves by hand, creating smooth walls, regular geometric shapes, or flowing curves. It is widely used in parks, street greenbelts, and courtyard landscaping maintenance, and is an indispensable professional piece of equipment for achieving large-area, high-precision hedge designs.

[0003] Hedge trimmers are typically equipped with upper and lower shearing blades for trimming. Under the influence of gravity, the upper and lower shearing blades remain almost in contact with each other, resulting in continuous friction between them during operation. This not only reduces the lifespan of the hedge trimmer but also increases power consumption.

[0004] Therefore, it is necessary to provide a hedge-raising machine to address the aforementioned technical problems. Utility Model Content

[0005] The purpose of this application is to provide a hedge trimmer that can solve the problem of shortened lifespan and increased power consumption caused by mutual friction between the upper and lower shearing blades of the hedge trimmer.

[0006] To achieve the above objectives, a specific embodiment of this application provides the following technical solution:

[0007] A hedge trimmer includes a housing, a drive unit, a transmission assembly, a first blade, and a second blade. The drive unit is installed inside the housing. The transmission assembly is connected to the output end of the drive unit. The drive unit drives the first blade to reciprocate. The drive unit also drives the second blade to reciprocate. The first blade has a first magnetic portion, and the second blade has a second magnetic portion. The adjacent surfaces of the first and second magnetic portions have opposite magnetic poles.

[0008] In one or more embodiments of this application, the hedge trimmer further includes fasteners, supports, and bushings;

[0009] The fastener and the support member cooperate to form the mounting space of the bushing. The bushing passes through the first blade and the second blade, and the height of the bushing is greater than the total thickness of the first blade and the second blade.

[0010] In one or more embodiments of this application, the fastener includes a column portion and a cap portion, the column portion passing through the support member and the bushing, and the cap portion forming the mounting space between the support member and the cap portion.

[0011] In one or more embodiments of this application, the hedge trimmer further includes a first abrasion-reducing plate located at the end of the bushing away from the support member.

[0012] In one or more embodiments of this application, the first anti-friction sheet has a third magnetic portion, and the third magnetic portion is disposed opposite to the adjacent magnetic poles of the first magnetic portion.

[0013] In one or more embodiments of this application, the mutual repulsion between the first abrasion reducing plate and the first blade is greater than the mutual repulsion between the first blade and the second blade.

[0014] In one or more embodiments of this application, the hedge trimmer further includes a second abrasion-reducing plate located between the bushing and the support member.

[0015] In one or more embodiments of this application, the second anti-friction sheet has a fourth magnetic portion, and the fourth magnetic portion is disposed opposite to the adjacent magnetic poles of the second magnetic portion.

[0016] In one or more embodiments of this application, the first blade is provided with a plurality of first waist-shaped holes, the second blade is provided with a plurality of second waist-shaped holes, and the first waist-shaped holes and the second waist-shaped holes correspond one to one. The fastener passes through the first waist-shaped holes and the second waist-shaped holes, and the bushing is at least partially disposed in the first waist-shaped holes and the second waist-shaped holes. The bushing is provided in a plurality of locations along the extension direction of the first blade or the second blade.

[0017] In one or more embodiments of this application, the first blade and / or the second blade are configured as magnetic blades formed by magnetization.

[0018] Compared with the prior art, the hedge trimmer of this application drives the transmission assembly through a drive component, causing the first and second blades to reciprocate to trim branches. The first magnetic part of the first blade and the second magnetic part of the second blade are arranged with their magnetic poles facing each other, so that the first blade and the second blade repel each other to reduce the normal force between them, thereby reducing friction between them, extending the service life of the hedge trimmer and improving its endurance.

[0026] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0027] Reference Figure 1 The hedge trimmer in one embodiment of this application includes a housing 1, a drive unit, a transmission assembly, a first blade 2, and a second blade 3.

[0028] Reference Figure 1 and Figure 2The drive component is installed inside the housing 1, and the transmission assembly is connected to the output end of the drive component. The drive component drives the first blade 2 and the second blade 3 to reciprocate. In this application, the drive component can be a motor, which is connected to the transmission assembly. The transmission assembly may include a transmission gear connected to the output end of the drive component, an eccentric shaft mounted on the transmission gear, and a rocker arm movably connected to the eccentric shaft. The rocker arm is movably connected to the first blade 2 and the second blade 3. The above is only an exemplary description of the transmission assembly in this embodiment. In other embodiments, other transmission structures may be used, and this application does not limit them. The drive component, the first blade 2, and the second blade 3 are connected by the transmission assembly, so that the drive component drives the first blade 2 and the second blade 3 to reciprocate to prune branches. The drive component and the transmission assembly are hidden inside the housing 1 and are not shown in the accompanying drawings of this embodiment.

[0029] Reference Figures 2 to 4 The first blade 2 has a first magnetic portion, and the second blade 3 has a second magnetic portion, with the adjacent surfaces of the first and second magnetic portions having magnetic poles of the same polarity facing each other. Specifically, the first and second magnetic portions can be magnets, or they can generate magnetism through magnetization. The first magnetic portion can be a portion or the entirety of the first blade 2. Similarly, the second magnetic portion can be a portion or the entirety of the second blade 3. This embodiment uses the example of the first blade 2 and / or the second blade 3 being magnetized magnetic blades for illustrative purposes, and this is not a limitation on the formation of the first and second magnetic portions.

[0030] Reference Figure 4 Because the first blade 2 has a first magnetic part and the second blade 3 has a second magnetic part, and the adjacent surfaces of the first magnetic part and the second magnetic part are arranged with the same magnetic poles facing each other, when the driving member drives the first blade 2 and the second blade 3 to reciprocate, the normal pressure between the first blade 2 and the second blade 3 is reduced under the action of like poles repelling each other, thereby reducing the friction between them, extending the service life of the hedge trimmer and improving its endurance.

[0031] Reference Figure 2 and Figure 4 The hedge trimmer of this application also includes fasteners 4, support members 5, and bushings 6.

[0032] Reference Figure 2 and Figure 4The first blade 2 has multiple first oblong holes 21, and the second blade 3 has multiple second oblong holes 31, with each first oblong hole 21 and second oblong hole 31 corresponding to the previous one. A fastener 4 passes through the first oblong holes 21 and second oblong holes 31. A bushing 6 is at least partially disposed within the first oblong holes 21 and second oblong holes 31, and multiple bushings 6 are provided along the extending direction of either the first blade 2 or the second blade 3. The first oblong holes 21 and second oblong holes 31 restrict the movement direction of the first blade 2 and the second blade 3, thereby driving them to perform relative shearing motion for pruning branches.

[0033] Reference Figure 3 and Figure 4 The fastener 4 and the support member 5 cooperate to form an installation space for the bushing 6. The bushing 6 passes through the first blade 2 and the second blade 3, and the height of the bushing 6 is greater than the total thickness of the first blade 2 and the second blade 3. The fastener 4 includes a column portion 41 and a cap portion 42. The column portion 41 passes through the support member 5 and the bushing 6, and the cap portion 42 forms an installation space with the support member 5. The fastener 4 can be a bolt, and can be used with washers and nuts to install the first blade 2, the second blade 3, and the bushing 6. The height of the bushing 6 is set to maintain a gap between the first blade 2 and the second blade 3.

[0034] Reference Figure 2 and Figure 4 In one optional embodiment, the hedge trimmer further includes a first abrasion-reducing plate 7, which is located at the end of the bushing 6 away from the support member 5. The first abrasion-reducing plate 7 can reduce the frictional wear of the first blade 2, thereby extending the service life of the hedge trimmer.

[0035] Reference Figure 2 and Figure 4 In one optional embodiment, the first abrasion-reducing plate 7 further includes a third magnetic portion, and the adjacent surfaces of the third magnetic portion and the first magnetic portion are arranged with the same magnetic poles facing each other. The mutual repulsion between the first abrasion-reducing plate 7 and the first blade 2 is greater than the mutual repulsion between the first blade 2 and the second blade 3. Therefore, under the action of like poles repulsion, in addition to reducing the normal pressure between the first blade 2 and the second blade 3, the normal pressure between the first blade 2 and the first abrasion-reducing plate 7 can also be reduced, thereby reducing the friction between the first abrasion-reducing plate 7, the first blade 2, and the second blade 3, extending the service life of the hedge trimmer and improving its endurance. The third magnetic portion can be a part of the first abrasion-reducing plate 7 or the entire area of ​​the first abrasion-reducing plate 7.

[0036] Reference Figure 2 and Figure 4In one optional embodiment, the hedge trimmer further includes a second friction-reducing plate 8, which is located between the bushing 6 and the support member 5. The second friction-reducing plate 8 can reduce the frictional wear of the second blade 3, thereby extending the service life of the hedge trimmer.

[0037] Reference Figure 2 and Figure 4 In one optional embodiment, the second abrasion-reducing plate 8 further includes a fourth magnetic portion, and the fourth magnetic portion and the adjacent surfaces of the second magnetic portion are arranged with their same magnetic poles facing each other. Therefore, under the repulsive effect of like poles, in addition to reducing the normal pressure between the first blade 2 and the second blade 3, the normal pressure between the second blade 3 and the second abrasion-reducing plate 8 can also be reduced, thereby reducing the friction between the second abrasion-reducing plate 8, the first blade 2, and the second blade 3, extending the service life of the hedge trimmer and improving its endurance. The fourth magnetic portion can be a part of the second abrasion-reducing plate 8 or the entire area of ​​the second abrasion-reducing plate 8.

[0038] Understandably, in one specific embodiment, the first abrasion-reducing plate 7 and the second abrasion-reducing plate 8 can be simultaneously provided to reduce the frictional wear of the first blade 2 and the second blade 3. Further, in another specific embodiment, the first abrasion-reducing plate 7 and the second abrasion-reducing plate 8 can also be simultaneously provided, with the first abrasion-reducing plate 7 having a third magnetic portion and the second abrasion-reducing plate 8 having a fourth magnetic portion, to reduce the mutual friction between the first abrasion-reducing plate 7, the first blade 2, the second blade 3, and the second abrasion-reducing plate 8, thereby extending the service life of the hedge trimmer and improving its endurance. The aforementioned first abrasion-reducing plate 7 and the second abrasion-reducing plate 8, as well as the corresponding third and fourth magnetic portions, can be partially or fully combined according to actual needs; this application will not provide specific examples of each combination.

[0039] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
