[0047] For reference Figures 1 to 4 As shown in the drawings, according to the embodiments of the present application, an independent drive type hedge trimmer, comprising a shell 1 and two staggered blades 4 extending out of the front end of the shell 1,

[0048] The shell 1 is internally provided with a rotating shaft 7, two crankshaft segments 72 are arranged on the rotating shaft 7, and the rear ends of the two staggered blades 4 are respectively hinged to the two crankshaft segments 72.

[0049] The two crankshaft segments 72 are different in the rotating phase of the rotating shaft 7, so that the two staggered blades 4 form a shearing mechanism during the rotation of the rotating shaft 7.

[0050] The other end of the rotating shaft 7 is engaged with one end of a transmission rod 6, and the other end of the transmission rod 6 extends out of the rear end of the shell 1 and is used for abutting a driving mechanism.

[0051] The utility model discloses a rotating shaft 7 is arranged in the shell 1, and the two staggered blades 4 are driven by the crankshaft, so that the two staggered blades 4 can trim the hedge, one end of the rotating shaft 7 is engaged with the transmission rod 6, and the part of the transmission rod 6 extending out of the shell 1 can be abutted with the driving mechanism, so that the driving mechanism does not need to be arranged in the shell 1, the structure in the shell 1 is simplified, the trimming part and the driving part of the hedge trimmer are arranged in a split mode, and the cost is saved.

[0052] The two staggered blades 4 arranged on the crankshaft segments 72 are staggered during reciprocating motion due to the different phases, so that the two staggered blades 4 constitute a scissors action and shear the hedge, and the effect of trimming the hedge is greatly improved.

[0053] Therefore, the independent driving type hedge trimmer belongs to the hedge trimmer without a driving part and needs external power to operate, the traditional hedge trimmer occupies the driving mechanism in the inapplicable state and wastes resources, the utility model is only abutted with the driving assembly such as the electric drill 9 during use, and the electric drill 9 can be used for other purposes when the independent driving type hedge trimmer is not used.

[0054] In some embodiments,

[0055] The axial direction of the transmission rod 6 and the axial direction of the rotating shaft 7 are perpendicular to each other and are engaged through bevel gears.

[0056] For the transmission structure of the hedge trimmer, a speed change structure usually needs to be additionally arranged, and straight-tooth speed change transmission is often used in the traditional hedge trimmer structure, and the utility model uses bevel gears to realize speed change transmission, the bevel gears are arranged on the abutting ends of the transmission rod 6 and the rotating shaft 7 and are engaged to complete bevel gear speed change transmission, the bevel gears have a large contact area, high transmission efficiency, small loss and long service life.

[0057] The bevel gear speed change can use bevel gears of various shapes to be engaged with each other, for example, two obtuse-angle bevel gears, so that the included angle between the transmission rod 6 and the rotating shaft 7 is also obtuse, and the utility model uses the perpendicular arrangement of the two, and the transmission effect is the best.

[0058] In some embodiments,

[0059] The hedge trimmer driving assembly further comprises a fixed rod 5, one end of which is fixed to the housing 1; the two staggered blades 4 are arranged on one side of the fixed rod 5 and reciprocate along the extension direction of the fixed rod 5.

[0060] The two staggered blades 4 are arranged on one side of the fixed rod 5 and reciprocate along the extension direction of the fixed rod 5, so that the stability of the movement of the two is enhanced; one end of the fixed rod 5 is fixed to the housing 1, so that the two staggered blades 4 will not be bent sideways when trimming the hedge.

[0061] In some embodiments,

[0062] The hedge trimmer blade 4 comprises a blade body, the two sides of which are provided with teeth; the blade body is provided with an avoiding hole 42 at the center, the fixed rod 5 is provided with a screw hole and a matching screw 8, and the screw 8 is connected to the avoiding hole 42 and the screw hole.

[0063] For the specific structure of the hedge trimmer blade 4, a straight blade can be used, the two sides of which are provided with teeth, and the center of which is provided with an avoiding hole 42, which is fixed to the fixed rod 5 by a screw 8.

[0064] The avoiding hole 42 is in the shape of a long strip in the extension direction of the fixed rod 5, so as to ensure the smooth completion of the reciprocating movement of the blade and the blade itself is limited by the screw 8.

[0065] In some embodiments,

[0066] One of the two staggered blades 4 is in sliding contact with the fixed rod 5.

[0067] The sliding contact between one staggered blade 4 and the fixed rod 5 can be achieved by providing a sliding groove on the fixed rod 5 and a corresponding protrusion on the staggered blade 4, and then combining the limiting of the screw 8 to prevent the staggered blade 4 from being dislocated during trimming and improve the stability of operation.

[0068] In some embodiments,

[0069] The two crankshaft segments 72 are arranged oppositely in the rotation phase of the rotating shaft 7.

[0070] The opposite arrangement of the two crankshaft segments 72 allows the two staggered blades 4 to reach the maximum displacement state and trim the hedge with good effect.

[0071] In some embodiments,

[0072] The housing 1 is provided with a handle 2 for holding the independent driving type hedge trimmer.

[0073] A handle 2 is arranged on the shell 1, facilitating hand-held operation; the shell 1 has few internal components, only transmission components, and is light in weight, facilitating hand-held operation and reducing the load on the operator.

[0074] In some embodiments,

[0075] A baffle 3 is arranged on the shell 1 between the two staggered blades 4 and the handle 2, for shielding the hedge cut by the two staggered blades 4.

[0076] The baffle 3 is arranged on the shell 1 between the two staggered blades 4 and the handle 2, and can shield the splashing hedge when the two staggered blades 4 move quickly to trim the hedge, reducing the injury to the operator.

[0077] According to another aspect of the present application, a hedge trimmer device set is provided, comprising the independently driven hedge trimmer and the driving mechanism as described above, and the driving mechanism is used for connecting the end of the transmission rod 6 extending out of the shell 1.

[0078] The part of the transmission rod 6 extending out of the shell 1 in the independently driven hedge trimmer is used for connecting the driving mechanism, and the connection and disconnection are convenient.

[0079] In some embodiments,

[0080] The driving mechanism is a hand drill 9, and the end of the transmission rod 6 extending out of the shell 1 is arranged in a drill bit clamp 91 of the hand drill 9.

[0081] The driving mechanism adopts the hand drill 9, the end of the transmission rod 6 extending out of the shell 1 is clamped in the drill bit clamp 91 of the hand drill 9, and the hand drill 9 is started, so that the two staggered blades 4 move and the hedge trimming is completed.

[0082] The hand drill 9 is used as the power source of the hedge trimmer, and is separately arranged, so that the function of the hand drill 9 is not affected, and the operation is simple, only the drill bit of the hand drill 9 is replaced, the transmission rod 6 is clamped by the drill bit clamp 91, and fastening can drive the two staggered blades 4 to complete the trimming operation.

[0083] It is easy for those skilled in the art to understand that the above-mentioned embodiments can be freely combined and superimposed without conflict.

[0084] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
