Description

Technical Field

[0001] The present application relates to the technical field of garden power tools, and in particular to a gasoline hedge trimmer blade assembly. Background Art

[0002] At present, hedge trimmers are mainly used for garden construction and tea harvesting. They usually include a handle, a driving mechanism, a transmission mechanism and a blade mechanism. The driving mechanism provides power to drive the blade mechanism to work through the transmission mechanism. The common blade mechanism includes two blades connected by bolts. The gears are rotated by the work of an electric motor, and the eccentric plates on the gears rotate together with the gears, driving the two blades to perform relative reciprocating motion to achieve pruning operations.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] The present application embodiment discloses a gasoline hedge trimmer blade assembly. Figure 1 A gasoline hedge trimmer blade set comprises a first blade 1, a second blade 2 and a telescopic component 3, wherein the first blade 1 and the second blade 2 are both provided with the telescopic component 3.

[0035] Reference Figure 1 and Figure 2The first blade 1 and the second blade 2 abut against each other. Assuming that the end at which the first blade 1 abuts against the second blade 2 is the lower end of the first blade 1, the end at which the second blade 2 abuts against the first blade 1 is the upper end of the second blade 2. Second tooth pieces 11 are integrally formed at the front and rear side walls of the first blade 1 and the second blade 2, and the second tooth piece 11 arranged on the front side wall is staggered with the second tooth piece 11 arranged on the rear side wall, that is, a second tooth piece 11 arranged on the front side wall is aligned with a position between two adjacent second tooth pieces 11 arranged on the rear side wall.

[0036] Reference Figure 1 and Figure 2 A mounting groove 12 is provided at the lower end of the first blade 1 and the upper end of the second blade 2. The mounting grooves 12 provided on the first blade 1 and the second blade 2 are connected. The telescopic component 3 is arranged in the mounting groove 12, and a first opening 121 is provided at the front end of the mounting groove 12.

[0037] Reference Figure 2 and Figure 3 The telescopic assembly 3 includes a telescopic rod 31 and a plurality of first teeth 32. The telescopic rod 31 is located in the mounting groove 12. A pair of first slide grooves 122 are provided at the bottom of the mounting groove 12. The first slide grooves 122 are provided along the direction of the first opening 121, and the first slide grooves 122 are communicated with the first opening 121. A pair of sliding rods 311 are provided at one end of the telescopic rod 31 abutting against the bottom of the mounting groove 12. The sliding rods 311 correspond one-to-one to the first slide grooves 122, so that the telescopic rod 31 can be extended and retracted toward the direction of the first opening 121.

[0038] Reference Figure 2 , Figure 4 and Figure 5 A limiting block 312 is welded at the front side wall and the rear side wall near the rear end of the telescopic rod 31. In order to ensure that the protruding limiting block 312 does not affect the extension and retraction of the telescopic rod 31 in the mounting groove 12, a lending groove 123 is opened at the front and rear side walls of the mounting groove 12. The lending groove 123 is opened in the direction of the first opening 121. The limiting block 312 is located in the lending groove 123. A second limiting plate 124 is integrally formed at the front end of the lending groove 123, so that the telescopic rod 31 is not easy to escape from the mounting groove 12 when extending and retracting.

[0039] Reference Figure 3 , Figure 4 and Figure 5In order to fix the telescopic rod 31 in the installation slot 12 when the telescopic rod 31 is not in use, a pair of snap-in balls 313 are provided at the rear end of the telescopic rod 31, and a pair of snap-in slots 125 are opened at corresponding positions of the installation slot 12. The snap-in balls 313 correspond to the snap-in slots 125 one by one. In order to prevent the snap-in balls 313 from getting stuck at the slot of the snap-in slot 125 when being inserted into the snap-in slot 125, a flared portion 1251 is provided at the slot wall of the snap-in slot 125 near the slot. In order to pull the telescopic rod 31 out of the installation slot 12, a handle 314 is welded at the front end of the telescopic rod 31.

[0040] Reference Figure 3 A plurality of equally spaced storage slots 315 are provided on the front and rear side walls of the telescopic rod 31, and the storage slots 315 provided on the front side wall are staggered with the storage slots 315 provided on the rear side wall, that is, one storage slot 315 provided on the front side wall is aligned with the position between two adjacent storage slots 315 provided on the rear side wall. In this embodiment, according to the size of the telescopic rod 31, eight storage slots 315 are preferably provided on the telescopic rod 31, and the eight storage slots 315 are divided into two groups, four storage slots 315 being one group, and the two groups of storage slots 315 are respectively provided on the front and rear side walls of the telescopic rod 31.

[0041] Reference Figure 3 The first tooth piece 32 is located in the storage slot 315. Therefore, in this embodiment, there are eight first tooth pieces 32, and the eight first tooth pieces 32 correspond to the eight storage slots 315 one by one. The front end of the storage slot 315 located on the front side wall is provided with a second opening 3151, and the rear end of the storage slot 315 located on the rear side wall is also provided with a second opening 3151.

[0042] Reference Figure 3 and Figure 6 A second slide groove 3152 is provided at the front and rear groove walls of the storage groove 315, and the second slide groove 3152 is opened in the direction of the second opening 3151. Slide blocks 321 are welded at the left and right side walls of the first tooth piece 32, and the slide block 321 is located in the second slide groove 3152. In order to prevent the first tooth piece 32 from easily falling out of the storage groove 315 when sliding in the storage groove 315 through the cooperation of the slide block 321 and the slide groove, a first limiting plate 3153 is integrally formed at one end of the second slide groove 3152 close to the second opening 3151.

[0043] Reference Figure 3 and Figure 6 A spring 3154 is welded to the groove wall of the second slide groove 3152 away from the first limiting plate 3153 integrally formed therewith, and one end of the spring 3154 away from the second slide groove 3152 is welded to the slider 321, so that the first tooth piece 32 can pop out of the storage groove 315 through the setting of the spring 3154.

[0044] The implementation principle of the blade set of a gasoline hedge trimmer according to the embodiment of the present application is as follows: when a wider hedge wall needs to be trimmed, the telescopic rod 31 is pulled out of the installation slot 12 by the handle 314, and the first tooth piece 32 originally in the storage slot 315 is ejected out of the storage slot 315 under the elastic force of the spring 3154, which is conducive to changing the size of the blade without disassembling the entire hedge trimmer;

[0045] When there is no need to lengthen the size of the blade, push the telescopic rod 31 back into the installation slot 12. When the telescopic rod 31 is pushed back into the installation slot 12, press the first tooth piece 32 back into the storage slot 315. Slowly push the telescopic rod 31 back into the installation slot 12 so that the end of the first tooth piece 32 away from the spring 3154 can abut against the slot wall of the storage slot 315. When the telescopic rod 31 is pushed until the locking ball 313 is locked with the locking slot 125, it is ready.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
