Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-7 shown, an adjustable pruning shear for big tree pruning includes: a connecting rod 1, a soft rubber pad 2, a first connecting block 3, a second connecting block 4 and a positioning bolt 5. There are 2 connecting rods 1. A soft rubber pad 2 is arranged on the side of the connecting rod 1. The two connecting rods 1 are respectively connected with a first connecting block 3 and a second connecting block 4. The first connecting block 3 and the second connecting block 4 are connected by a positioning bolt 5. A quick-release mechanism 6 is arranged on the side of the first connecting block 3 and the second connecting block 4. A protection mechanism 8 is arranged on the side of the quick-release mechanism 6. An adjusting mechanism 7 is arranged inside the connecting rod 1. When the device is in use, first remove the protection mechanism 8, then install the scissors blade 62 through the quick-release mechanism 6, and then the big tree can be pruned. During the use process, the adjusting mechanism 7 can be started for adjustment according to the actual use situation, so that the device is suitable for a variety of occasions.

[0025] The quick-release mechanism 6 includes a clamping block 61, a scissors blade 62 and a first bolt 63. The clamping block 61 is snap-connected to the sides of the first connecting block 3 and the second connecting block 4. The scissors blade 62 is connected to the side of the clamping block 61. The first connecting block 3 and the second connecting block 4 are both threadedly connected with a first bolt 63, and the first bolt 63 is threadedly connected with the clamping block 61. When the device is in use, first snap-insert the scissors blade 62 connected to the clamping block 61 into the sides of the first connecting block 3 and the second connecting block 4, and then position it through the first bolt 63.

[0026] First grooves 64 are symmetrically formed on the sides of the first connecting block 3 and the second connecting block 4. A second bolt 65 is threadedly connected inside the first groove 64, and the second bolt 65 is threadedly connected with the clamping block 61.

[0027] The first connecting block 3 and the side of the second connecting block 4 are symmetrically provided with second grooves 66. A third bolt 67 is threadedly connected to the inner side of the second groove 66, and the third bolt 67 is threadedly connected to the clamping block 61. When the device is in use, after the clamping block 61 is engaged, the second bolt 65, the third bolt 67 and the clamping block 61 are threadedly connected at the same time, so as to assist in positioning the clamping block 61.

[0028] The adjusting mechanism 7 includes a driving motor 71, a threaded rod 72 and a connecting shell 73. The driving motor 71 is embedded in the connecting rod 1, the output shaft of the driving motor 71 is connected to the threaded rod 72, and the connecting shell 73 is threadedly connected to the side of the threaded rod 72.

[0029] Sliding grooves are provided inside the connecting rod 1, and sliding grooves 74 are symmetrically provided inside the sliding grooves. Sliders 75 are symmetrically provided on the side of the connecting shell 73, and the sliders 75 are slidably arranged inside the sliding grooves 74. When the device is in use, when the power arm needs to be adjusted, the driving motor 71 is started, the threaded rod 72 is driven to rotate by the driving motor 71, and the slider 75 on the side of the connecting shell 73 slides inside the sliding groove 74 during the rotation of the threaded rod 72, so that the connecting shell 73 extends out to adjust the power arm.

[0030] The protection mechanism 8 includes a protection shell 81, a magnetic rod 82 and a spring hook 83. The protection shell 81 is provided on the side of the first connecting block 3 and the second connecting block 4. The magnetic rod 82 is symmetrically and slidably connected to the side of the protection shell 81. The magnetic rod 82 is magnetically connected to the first connecting block 3 and the second connecting block 4. Spring hooks 83 are symmetrically provided on the side of the magnetic rod 82, and the other side of the spring hook 83 is connected to the protection shell 81. When the device is in use, the protection shell 81 is engaged on the side of the scissors blade 62 for protection. At the same time, it is clamped by the magnetic connection between the magnetic rod 82 and the first connecting block 3 and the second connecting block 4. At the same time, when the protection shell 81 needs to be removed, by pulling the magnetic rod 82, the magnetic rod 82 and the first connecting block 3 and the second connecting block 4 lose the engagement, and at the same time, the magnetic rod 82 can be pulled by the spring hook 83 to prevent the magnetic rod 82 from falling off.

[0031] When the present utility model is in use, first, the scissors blade 62 connected to the clamping block 61 is engaged and inserted into the sides of the first connecting block 3 and the second connecting block 4, and then positioned by the first bolt 63. After the clamping block 61 is engaged, the second bolt 65, the third bolt 67 and the clamping block 61 are threadedly connected at the same time to assist in positioning the clamping block 61. At the same time, when the scissors blade 62 needs to be replaced during use, the clamping block 61 can be disassembled for replacement;

[0032] When it is necessary to adjust the power arm, start the drive motor 71, drive the threaded rod 72 to rotate through the drive motor 71. During the rotation of the threaded rod 72, drive the slider 75 on the side of the connection shell 73 to slide inside the chute 74, so that the connection shell 73 extends to adjust the power arm;

[0033] After use, snap the protective shell 81 on the side of the scissor blade 62 for protection. At the same time, the magnetic rod 82 is magnetically connected to the first connecting block 3 and the second connecting block 4 for snapping, so as to provide protection. At the same time, when it is necessary to remove the protective shell 81, pull the magnetic rod 82 so that the magnetic rod 82 loses the snap connection with the first connecting block 3 and the second connecting block 4. At the same time, the magnetic rod 82 can be pulled by the spring hook 83 to prevent the magnetic rod 82 from falling off.

[0034] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard 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.
