DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] Example 1:

[0025] A blueberry flower-promoting pruning device comprises a knife bar 1 and a movable plate 2. An adjustment mechanism 3 is provided on one side of the knife bar 1. The adjustment mechanism 3 comprises a movable plate 301, a connecting plate 302, a gripping rod 303, a movable groove 304, and a spring 305. One side of the movable plate 301 is connected to one side of the connecting plate 302, and one end of the connecting plate 302 is connected to one end of the gripping rod 303. A movable groove 304 is provided on the inner side of the knife bar 1. A spring 305 is fixedly installed between the inner side of the knife bar 1 and one end of the connecting plate 302. A fixed plate 306 is installed on one side of the knife bar 1. A limiting rod 307 is slidably connected to the inner side of the fixed plate 306. A blade 310 is installed on one end of the knife bar 1. A compression spring 311 is installed on one side of the knife bar 1.

[0026] In this embodiment, there are two movable plates 301, which are symmetrically distributed on both sides of the connecting plate 302. One side of the movable plate 301 is slidably connected to the inner wall of the movable groove 304. There are two gripping rods 303, which are symmetrically distributed on one end of the two knife rods 1. One end of the limiting rod 1 307 is plugged into one end of the limiting hole 308. A spring 2 309 is fixedly installed between one side of the limiting rod 1 307 and the inner side of the fixed plate 306, so that the blueberry flowers can be pruned quickly and conveniently, and the connecting plate 302 can be locked and unlocked quickly and conveniently.

[0027] Furthermore, there are two springs 305, which are symmetrically distributed on one end of the two connecting plates 302. The fixing plate 306 is U-shaped. A limiting hole 308 is provided on one side of the connecting plate 302. There are seven limiting holes 308, which are sequentially distributed on one side of the connecting plate 302. This allows for quick and convenient adjustment of the position of the grip 303, thereby enabling better adjustment of the length of the pruning device, and thus enabling better pruning of different blueberry flowers.

[0028] Furthermore, one side of the knife rod 1 is connected to one side of the movable plate 2, a movable plate 301 is provided inside the knife rod 1, and one end of the gripping rod 303 is connected to one end of the mounting plate 402.

[0029] When in use, when it is necessary to use it, the operator holds the entire device in hand to prune the blueberry flowers. When pruning, the operator holds the handle 303 and applies force at the same time to rotate the knife bar 1, so that the two blades 310 are close to each other, so that the blueberry flowers can be pruned. When the knife bar 1 rotates, the compression spring 311 can be squeezed, so that the pruning work can be performed better and more labor-saving. When it is necessary to prune blueberry flowers according to different lengths, the operator pulls the limit rod 1 307 to slide on the fixed plate 306, thereby squeezing the spring 2 309, and as the limit rod 1 307 slides, it can be drawn out of the limit hole 308 on one side of the connecting plate 302. The limit fixation of the connecting plate 302 can be cancelled. At this time, the connecting plate 302 is driven to move by pulling the handle 303, and the connecting plate 302 is driven to slide on the moving groove 304 by the movement of the connecting plate 302, thereby increasing the stability of the connecting plate 302 when moving. As the connecting plate 302 moves, the spring 1 305 can be stretched. When the adjustment is completed, the limit rod 1 307 is released, and the limit rod 1 307 can be reset by the elastic force of the spring 2 309, and then the limit rod 1 307 can be inserted into the limit hole 308 to complete the limit fixation of the connecting plate 302, thereby adjusting the distance between the handle 303 and the knife rod 1, thereby increasing the length of the pruning knife, and then being able to prune different blueberry flowers, which is more convenient for the operator to use.

[0030] Example 2:

[0031] On the basis of the first embodiment, a protection mechanism 4 is provided at one end of the knife bar 1;

[0032] The protection mechanism 4 includes a mounting rod 401, a mounting plate 402, a sliding plate 403, an adjustment rod 404, and an adjustment plate 405. One end of the gripping rod 303 is connected to one end of the mounting rod 401. The inner side of the mounting plate 402 is slidably connected to both ends of the sliding plate 403. One end of the sliding plate 403 is connected to one end of the adjustment rod 404. The other end of the adjustment rod 404 is mounted with the adjustment plate 405. A second limit rod 406 is mounted on one side of the sliding plate 403.

[0033] In this embodiment, the mounting rod 401 is L-shaped, with a fixing hole formed on one side of the mounting rod 401 and a mounting hole formed on one side of the mounting plate 402. One end of the second limiting rod 406 is plugged into the fixing hole, so that the second limiting rod 406 can be quickly and conveniently inserted into the mounting rod 401, thereby better locking and unlocking the trimming device.

[0034] Furthermore, a spring 407 is fixedly installed between one side of the sliding plate 403 and the inner side of the mounting plate 402. An adjustment slot is provided on one side of the mounting plate 402, and both sides of the adjustment rod 404 are slidably connected to the inside of the adjustment slot, so that the mounting rod 401 can be locked and unlocked quickly and conveniently, and can be better stored and used.

[0035] When in use, when it is necessary to use it, the operator can hold the entire device to prune the blueberry flowers, and can quickly and conveniently adjust the length of the pruning knife through the adjustment mechanism 3, so that different blueberry flowers can be pruned better. At this time, when pruning is not needed, the operator presses the two grips 303 to make them move toward the middle, and then the mounting rod 401 can be driven to move toward the mounting plate 402, so that the mounting rod 401 can be inserted into the mounting hole on one side of the mounting plate 402. When the mounting rod 401 is inserted into the mounting hole, it can squeeze the limiting rod 2 406 to move, and the movement of the limiting rod 2 406 drives the sliding plate 403 to slide. The sliding of the sliding plate 403 can squeeze the spring 3 407, and drive the adjusting rod 404 and the adjusting rod 404 to move. The plate 405 moves, and as the mounting rod 401 continues to move, the squeezing of the second limit rod 406 can be cancelled, and the second limit rod 406 can be reset and inserted into the fixing hole provided on one side of the mounting rod 401 by the elastic force of the third spring 407, so that the mounting rod 401 can be limited and fixed, and the two grip rods 303 can be limited and fixed, and the entire pruning knife can be limited and fixed. When the pruning knife needs to be opened, the adjustment plate 405 is pulled to move the adjustment rod 404, and the adjustment rod 404 moves to move the sliding plate 403, and the sliding plate 403 moves to move the second limit rod 406, so that the second limit rod 406 can be pulled out of the fixing hole, canceling the limit fixation of the mounting rod 401, and the pruning knife can be opened to perform pruning work.
