[0003] When blueberries are planted, it is usually necessary to prune the blueberry branches. Currently, when pruning blueberry branches during growth, scissors are generally used to directional prune the branches. Although the fulcrums of some scissors have the effect of convenient operation when used, due to the overall low height of the blueberry tree, when pruning the blueberry branches with scissors, the operator needs to bend over or squat to operate. Therefore, when the operator prunes the blueberry branches, the two arms need to be crossed to exert force, which makes it relatively laborious for the operator to control the scissors to prune the branches to a certain extent, resulting in low efficiency of blueberry branch pruning.

[0030] See also Figure 1-5 The utility model provides a technical solution: a blueberry pruning device, comprising an outer bracket body 1, a power sleeve rod 2 is slidably installed on the surface of the outer bracket body 1, a limiting slide groove 3 is arranged on the inner side of the outer bracket body 1, a limiting slide plate 4 is slidably installed on the inner wall of the limiting slide groove 3, the surface of the limiting slide plate 4 is fixedly installed on the inner side of the power sleeve rod 2, an inner sliding rod 5 is fixedly installed on the surface of the limiting slide plate 4, the surface of the inner sliding rod 5 is slidably installed on the inner side of the outer bracket body 1, and a pruning knife 8 is arranged on the end of the inner sliding rod 5 away from the limiting slide plate 4.
[0031] Specifically, when the pruning knife 8 needs to be used, the operator only needs to control the power sleeve rod 2 to slide on the surface of the outer bracket body 1, and then the power sleeve rod 2 drives the pruning knife 8 to slide out on the inner side of the outer bracket body 1 through the inner sliding rod 5 on the limiting slide plate 4 to prune the blueberry branches.
[0032] Furthermore, an external screw ring 9 is threadedly installed on the surface of the external bracket body 1, and a positioning cap 10 is rotatably installed on the surface of the external screw ring 9. A guide groove 11 is opened on the inner side of the positioning cap 10, and the surface of the pruning knife 8 is slidably installed on the inner wall of the guide groove 11 on the positioning cap 10. When the pruning knife 8 needs to be replaced, the operator controls the external screw ring 9 to adjust the thread on the surface of the external bracket body 1, and then the external screw ring 9 rotates between the positioning cap 10 to make the pruning knife 8 slide out from the inner side of the positioning cap 10. At this time, the pruning knife 8 can be conveniently replaced.
[0033] Furthermore, a positioning bracket 12 is fixedly installed on the surface of the positioning cap 10, and the positioning bracket 12 is in a J-shape. A through groove 13 is opened on the surface of the positioning bracket 12, and a first elastic component 14 is slidably installed on the surface of the outer bracket body 1. The two ends of the first elastic component 14 are respectively fixedly installed on the surface of the outer bracket body 1 and the surface of the power sleeve rod 2. When the operator needs to prune the blueberry branches, the operator only needs to control the positioning bracket 12 on the outer bracket body 1 to dock with the branches to be pruned, and use the J-shape of the positioning bracket 12 to form a limiting hook for the blueberry branch. At this time, the operator controls the power sleeve rod 2 to slide on the surface of the outer bracket body 1, and the power sleeve rod 2 pushes the pruning knife 8 to dock with the positioning bracket 12, and then the pruning knife 8 performs a pruning operation on the limited branches at the through groove 13.
[0034] Furthermore, an auxiliary ring 17 is welded on the surface of the power sleeve rod 2, and a rubber pad 18 is bonded and installed on the surface of the auxiliary ring 17. The auxiliary ring 17 is provided on the surface of the power sleeve rod 2 to assist the operator in controlling the movement of the power sleeve rod 2, and the rubber pad 18 on the auxiliary ring 17 assists the contact between the operator and the auxiliary ring 17, thereby protecting the operator's hands to a certain extent and reducing the disadvantage of the auxiliary ring 17 being damaged by direct contact with the operator's hands.
[0035] Furthermore, a limit ring 16 is threadedly installed on the surface of the outer bracket body 1, and the shape of the limit ring 16 is an I-shaped one. The I-shaped shape of the limit ring 16 can enable the operator's hand to form an effective control limit on the outer bracket body 1, so that the operator can control the pruning device to form convenient movement, and through the thread adjustment between the limit ring 16 and the outer bracket body 1, the device can be flexibly adjusted to a range of use, and the device ensures the ease of pruning blueberry branches, improves the disadvantage of the traditional blueberry branch pruning with scissors, thereby improving the speed of the blueberry branch pruning operation and ensuring the ease of operation when pruning the blueberry branches.
[0036] Furthermore, a positioning support plate 6 is fixedly installed on the surface of the inner sliding rod 5, a positioning support groove 7 is opened on the inner side of the positioning support plate 6, the surface of the pruning knife 8 is slidably installed on the inner wall of the positioning support groove 7, a fixing groove 19 is opened on the surface of the pruning knife 8, a fixing rod 20 is slidably installed on the inner side of the positioning support plate 6, and a second elastic component 15 is slidably sleeved on the surface of the fixing rod 20, and both ends of the second elastic component 15 are respectively fixedly installed on the surface of the fixing rod 20 and the inner side of the positioning support plate 6, and the surface of the positioning support plate 6 is slidably installed on the inner side of the outer bracket body 1.
[0037] Specifically, when the pruning knife 8 needs to be replaced, the operator controls the external screw ring 9 to drive the positioning cap 10 to separate from the pruning knife 8. At this time, since the positioning cap 10 no longer blocks the positioning support plate 6, the operator takes out the pruning knife 8 from the inner side of the positioning support plate 6, and then replaces the new pruning knife 8 until the pruning knife 8 reaches the predetermined position. At this time, the fixing rod 20 is driven by the pulling force of the stretched second elastic component 15 to enter the inner wall of the fixing groove 19 to limit the pruning knife 8 until the positioning cap 10 and the external bracket body 1 are installed, so the pruning knife 8 can be replaced and positioned.
[0038] Working principle: A blueberry pruning device. When an operator needs to prune blueberry branches, the operator only needs to control the positioning bracket 12 on the outer bracket body 1 to dock with the branches to be pruned, and use the J-shape of the positioning bracket 12 to form a limiting hook for the blueberry branches. At this time, the operator controls the power sleeve rod 2 to slide on the surface of the outer bracket body 1, and the power sleeve rod 2 pushes the pruning knife 8 to dock with the positioning bracket 12, and then the pruning knife 8 prunes the limited branches at the through groove 13.
[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
