DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1 to 4 The utility model provides a technical solution: a landscaping pruning device, including a reciprocating drive mechanism, the reciprocating drive mechanism includes a drive housing 1, such as Figure 4 As shown, a driving motor 15 with a rotating shaft vertically downward is provided at one end of the driving housing 1, and the bottom of the rotating shaft is vertically connected to the middle of the swing arm 26. A connecting shaft 27 is vertically rotatably installed at one end of the swing arm 26. The connecting shaft 27 is specifically installed inside one end of the swing arm 26 through a bearing. The bottom of the connecting shaft 27 is vertically rotatably connected to one end of the driving arm 28. The bottom of the connecting shaft 27 is specifically installed in the end of the driving arm 28 through a bearing. The driving arm 28 is horizontally arranged, and the end of the driving arm 28 away from the connecting shaft 27 is rotatably connected to the end of the movable shaft 29.

[0029] The movable shaft 29 is movably arranged in the guide seat 30, and the guide seat 30 is fixed to the bottom of the driving housing 1, so when the driving motor 15 rotates, it can drive the swing arm 26 to rotate, and the swing arm 26 will drive the driving arm 28 through the connecting shaft 27 to push the movable shaft 29 to reciprocate in the guide seat 30. Figure 4As shown, one end of the movable shaft 29 away from the driving arm 28 extends to the outside of the driving housing 1, and the other end of the movable shaft 29 away from the driving arm 28 is connected to a mounting shaft 6 extending vertically upward, so that the mounting shaft 6 can also reciprocate outside the driving housing 1.

[0030] like Figure 4 As shown, a control board 4 and a rechargeable battery pack 25 connected to the control board 4 are further provided in the drive housing 1. The control board 4 is connected to the drive motor 15. The control board 4 is also connected to a switch 24. The switch can be set on the surface of the drive housing 1 for easy control by the operator. The charging port of the rechargeable battery pack 25 is also set on the surface of the drive housing 1 for easy charging. The charging port is connected to the control board. The control board 4 is a PCB control circuit board.

[0031] like Figure 1 and Figure 2 As shown, the drive housing 1 is provided with a second handle 5 at one end close to the bar seat 10. The second handle 5 is in a "C" shape. A first handle 2 is provided at the end of the top of the drive housing 1 away from the second handle 5. The first handle 2 is in an "L" shape. In order to meet the height matching between the first handle 2 and the second handle 5, a groove 3 is provided at the end of the top of the drive housing 1 away from the second handle 5. The first handle 2 is located in the groove 3. The operator holds the first handle 2 with one hand and the second handle 5 with the other hand to facilitate lifting the drive housing 1. When in use, as shown in FIG. Figure 4 As shown, the switch 24 can also be arranged on the first handle 2, which is convenient for the operator to touch directly with a finger.

[0032] Furthermore, a strip seat 10 is horizontally connected to the bottom of one end of the drive housing 1 close to the drive motor 15, and a first saw blade 12 and a second saw blade 19 are sequentially arranged above the strip seat 10;

[0033] The top of the strip seat 10 is provided with at least two linearly arranged supports 17 ( Figure 1 and Figure 2 There are three supports 17 in the figure. First fixing holes 18 are defined on the surface of the first saw blade 12, corresponding to the positions of the supports 17. The first saw blade 12 is placed on the strip-shaped support 10, with the supports 17 placed within the first fixing holes 18. A second saw blade 19 is defined on its surface, corresponding to the positions of the supports 17. The second saw blade 19 is placed on top of the first saw blade 12, with the supports 17 placed within the strip openings 21. The strip openings 21 and the first fixing holes 18 are clearance-matched with the supports 17 (the tolerance can be zero).

[0034] It should be noted that after the first fixing hole 18 is buckled onto the strip seat 10, the first saw blade 12 is fixed above the strip seat 10, that is, the first saw blade 12 is stationary; and the second saw blade 19 can move in a straight line along the support 17 through the strip opening 21. The size of the strip opening 21 allows the second saw blade 19 to and can only move in a straight line along the support 17.

[0035] like Figure 3 As shown, a connecting piece 13 is provided at one end of the second saw blade 19 close to the reciprocating drive device, and a mounting hole 14 is provided at the end of the connecting piece 13. The mounting hole 14 is connected to the reciprocating drive device. Figure 4 As shown, the movable shaft 29 extends to the bottom of the connecting piece 13. When the second saw blade 19 is placed on the top of the first saw blade 12, the mounting hole 14 is sleeved on the mounting shaft 6, so that the reciprocating mounting shaft 6 can drive the second saw blade 19 to reciprocate along the support 17. Figure 1 and Figure 2 As shown, the saw teeth 11 on both sides of the first saw blade 12 and the second saw blade 19 are arranged at intervals, and the saw teeth 11 are located outside the two sides of the bar seat 10, so when the second saw blade 19 reciprocates, the saw teeth 11 of the upper and lower layers are continuously separated and engaged, so that the upper and lower layers can shear the objects located between the saw teeth 11.

[0036] In this application, in order to limit the top of the second saw blade 19 to prevent the second saw blade 19 from falling, as shown in FIG. Figure 1 and Figure 3 As shown, a strip plate 7 is provided above the second saw blade 19, and the strip plate 7 is detachably connected to the top of the support 17. Figure 1 and Figure 3 As shown, a first mounting seat 9 is provided on the top of the end of the strip seat 10 away from the drive housing 1, and second mounting seats 23 are provided on both sides of the end of the strip seat 10 close to the drive housing 1. The second mounting seats 23 are located on both sides of the connecting piece 13. Threaded holes 8 are provided on the tops of the support 17, the second mounting seat 23 and the first mounting seat 9, respectively. A second fixing hole 20 is provided on the top of the strip plate 7 at a position corresponding to the threaded hole 8. The second fixing hole 20 is fastened to the threaded hole 8 by bolts.

[0037] The sum of the thicknesses of the second saw blade 19 and the first saw blade 12 matches the height of the support 17, so that the clearance between the strip plate 7 and the second saw blade 19 is matched (the matching tolerance can be zero), so when the second saw blade 19 reciprocates, the second saw blade 19 can reciprocate stably above the strip plate 7 and the first saw blade 12.

[0038] Based on the above embodiment, further optimization can be performed by providing a counterweight 16 at one end of the swing arm 26 away from the connecting shaft 27. The counterweight 16 can keep the swing arm 26 balanced when rotating rapidly, thereby preventing the entire trimming device from shaking.

[0039] Based on the above embodiment, it can be further optimized that a fan is provided on the rotating shaft of the driving motor 15 (as shown by the arrow A in 4). Figure 1 As shown, a ventilation window is provided on the surface of the drive housing 1 corresponding to the drive motor 15 .

[0040] Based on the above embodiment, it can be further optimized to provide a battery compartment (such as Figure 4 The rechargeable battery pack 25 is placed in the battery compartment, and an end cover 22 is provided at the end of the drive housing 1 away from the drive motor 15. The rechargeable battery pack 25 can be taken out after opening the end cover 22. In this way, multiple rechargeable battery packs 25 can be prepared for use. After the first rechargeable battery pack 25 is used up, another rechargeable battery pack 25 can be replaced.
