[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a single-blade hedge trimmer, including a drive box 1 and a blade holder 2. The drive box 1 and the blade holder 2 are fixedly connected. The drive box 1 is used to drive the moving blade 9. The drive box 1 has a drive gear 11 and a driven gear 12 inside. The drive gear 11 and the driven gear 12 mesh and transmit power. The driven gear 12 is provided with a protrusion 13. The end of the moving blade 9 near the driven gear 12 is provided with a connecting seat 91. The connecting seat 91 is provided with a guide groove 92. The protrusion 13 is located in the guide groove 92. The blade holder 2 includes a fixed blade 21. The drive box 1 is connected to a first handle 6 through a telescopic rod 5. The drive gear 11 is driven by a motor 3. The first handle 6 is provided with a switch 61. The moving blade 9 and the blade holder 2 are slidably connected.

[0023] The telescopic pole 5 is extendable. In daily use, the telescopic pole 5 is folded together, and the single-blade hedge trimmer can meet the needs of daily use. When it is necessary to trim hedges at high places or in distant places, the telescopic pole 5 is unfolded to extend the total length of the hedge trimmer, increase the coverage area of ​​the hedge trimmer, realize long-distance trimming, solve the problem of limited working radius, improve the flexibility of the hedge trimmer, and meet different usage needs.

[0024] When the motor 3 is working, it drives the drive gear 11 to rotate. Through the meshing transmission between the teeth, it drives the driven gear 12 to rotate. The driven gear 12 drives the upper protrusion 13 to move. The protrusion 13 drives the connecting seat 91 to move. The connecting seat 91 drives the moving blade 9 at one end to move. The moving blade 9 moves relative to the fixed blade 21, converting the rotational motion of the motor 3 into the linear reciprocating motion of the moving blade 9. When the moving blade 9 moves forward, it forms a closed shearing surface with the fixed blade 21, cutting the branches. When the moving blade 9 retracts, the fixed blade 21 remains stationary, preparing for the next cut. Through high-frequency reciprocating motion, continuous pruning of the hedge is achieved.

[0025] The telescopic rod 5 includes a first sleeve 51, a second sleeve 52 and a third sleeve 53, which can extend and retract in multiple stages.

[0026] The first sleeve 51 is fixedly connected to the drive box 1, one end of the second sleeve 52 is slidably embedded in the first sleeve 51, and the first sleeve 51 and the second sleeve 52 are fixedly connected by the first tightening screw 54.

[0027] Loosen the first tightening screw 54, and the second sleeve 52 can slide relative to the first sleeve 51. At this time, the extension length of the second sleeve 52 can be adjusted. After the adjustment is completed, tighten the first tightening screw 54 to fix it.

[0028] One end of the third sleeve 53 is slidably embedded in the second sleeve 52, and the second sleeve 52 and the third sleeve 53 are fixedly connected by the second tightening screw 55.

[0029] Loosen the second tightening screw 55, and the third sleeve 53 can slide relative to the second sleeve 52. At this time, the extension length of the third sleeve 53 can be adjusted. After the adjustment is completed, tighten the second tightening screw 55 to fix it.

[0030] One end of the first handrail 6 is slidably embedded in the third sleeve 53, and the third sleeve 53 and the first handrail 6 are fixedly connected by the third tightening screw 56.

[0031] Loosen the third tightening screw 56, and one end of the first handrail 6 can slide relative to the third sleeve 53. At this time, the extension length of the first handrail 6 can be adjusted. After the adjustment is completed, tighten the third tightening screw 56 to fix it.

[0032] The drive box 1 is equipped with a battery compartment 4, which contains a power bank.

[0033] A power interface 41 is provided on one side of the battery compartment 4.

[0034] The hedge trimmer is powered by electricity, emits no harmful gases during operation, and has low noise. It is lighter than gasoline-powered models and can be started and stopped with a single button via switch 61, making it easy to operate. The battery compartment 4 supports quick replacement with a mobile power source, making battery swapping convenient. It can also be connected to an extension cord via power interface 41 to connect to a power source.

[0035] The tool holder 2 has multiple sets of connection holes 22. A baffle 8 is installed on the tool holder 2. The baffle 8 is fixedly connected to the tool holder 2 by screws. The installation and removal of the baffle 8 is convenient, and it is easy to replace and maintain. The baffle 8 is used to prevent splashing injuries.

[0036] The knife holder 2 is equipped with a second handrail 7. Both the first handrail 6 and the second handrail 7 are covered with memory foam and non-slip rubber. The ergonomic handles distribute pressure and reduce local fatigue.

[0037] Working principle: When in use, it is powered by a mobile power supply or an extension cord. Hold the first handle 6 and the second handle 7 with both hands respectively to operate. Turn it on and off via switch 61. When starting, the rotational motion of the motor 3 is converted into the linear reciprocating motion of the moving blade 9. When the moving blade 9 moves forward, it forms a closed cutting surface with the fixed blade 21 to cut the branches. When the moving blade 9 retracts, the fixed blade 21 remains stationary, preparing for the next cut. Through high-frequency reciprocating motion, continuous trimming of hedges is achieved. In daily use, the telescopic pole 5 is folded together, and the single-blade hedge trimmer can meet the needs of daily use. When it is necessary to trim hedges at high places or in distant places, the telescopic pole 5 is unfolded to extend the total length of the hedge trimmer, increase the coverage area of ​​the hedge trimmer, and achieve long-distance trimming.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
