[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0032] Refer to Figure 1The utility model provides a kind of embodiment provided by the utility model: a dwarf ginkgo planting pruning device, the shape of positioning ring 1 is half annular, the middle part of positioning ring 1 is equipped with the slot 7 of passing in, the slot 7 is divided into two by positioning ring 1, and the outside of positioning ring 1 is provided with the protrusion of connecting its half annular two parts, the outer arc surface of positioning ring 1 is fixedly connected with control rod 2, the rear end of control rod 2 is rotatably connected with rotating rod 3, and the shape and length of rotating rod 3 are consistent with control rod 2, the rear end of control rod 2 and the front end of rotating rod 3 are in the same plane, control rod 2 and rotating rod 3 are cross-shaped, one end of control rod 2 away from positioning ring 1 is fixedly connected with hand ring 4, the shape of hand ring 4 is half cylinder, and the inside of hand ring 4 is provided with hollow, the number of hand ring 4 is provided with two, the outer wall of another hand ring 4 is fixedly connected with the end of rotating rod 3, one end of rotating rod 3 away from hand ring 4 is fixedly connected with pruning ring 5, when the plane position of two hand rings 4 is adhered, the area of the region formed by pruning ring 5 and the inner arc surface of positioning ring 1 is exactly zero, the depth of the slot 7 is deeper than the thickness of pruning ring 5, by the setting of the slot 7, it is guaranteed that pruning ring 5 can enter the slot 7.

[0033] With reference to Figure 2 - Figure 4 The inside of pruning ring 5 is provided with pruning mechanism 6, and the front and rear ends of sprocket 61 are rotatably connected with the inner wall of pruning ring 5, the number of sprocket 61 is provided with two, the outside of sprocket 61 is provided with chain 62, and the front and rear ends of chain 62 are fixedly connected with positioning rod 63.

[0034] With reference to Figure 2 、 Figure 4 and Figure 5The inner wall of the trimming ring 5 is provided with a positioning groove 64. The shape of the positioning groove 64 ensures that the shape of the chain 62 is consistent with it. The front and rear ends of the positioning rod 63 are arranged in the inner part of the positioning groove 64. The shape of the positioning rod 63 is a cylinder. The width of the positioning groove 64 is consistent with the diameter of the positioning rod 63. The arrangement of the positioning groove 64 and the positioning rod 63 ensures that the chain 62 can maintain an arc shape and will not be straightened or in a loose state. The outer wall of the chain 62 is fixedly connected with a trimming block 65. The shape of the positioning groove 64 is an arc slot. The shape of the trimming block 65 is a cone. The shape of the trimming block 65 ensures that the trimming block 65 has the ability to cut ginkgo branches. The front end of the trimming ring 5 is fixedly connected with a mounting block 66. The inner wall of the positioning ring 1 at the front end of the penetrating groove 7 is provided with a moving groove 8. The shape of the moving groove 8 is a circle formed by the intersection of the positioning ring 1 and the moving groove 8, with the intersection point of the rotating rod 3 and the control rod 2 as the center and the farthest distance between the mounting block 66 and the control rod 2 as the side length. The depth of the moving groove 8 is deeper than the length of the mounting block 66. The inner wall of the mounting block 66 is fixedly connected with a motor 67. The output shaft of the motor 67 penetrates the inner wall of the trimming ring 5 and is fixedly connected with the front end of the sprocket 61. The shape of the trimming ring 5 is a half ring shape consistent with the inner and outer diameters of the positioning ring 1. The inner arc surface of the trimming ring 5 and the inner arc surface of the positioning ring 1 are located at one end close to each other. The shape and position of the trimming ring 5 and the positioning ring 1 ensure that the ginkgo branches can be fixed in the area formed by the inner arc surfaces of the trimming ring 5 and the positioning ring 1 during cutting.

[0035] Working principle: in use, the user first moves the two hand-held rings 4 away from each other, so that the two hand-held rings 4 drive the lower ends of the control rod 2 and the rotating rod 3 to move away from each other, so that the upper ends of the control rod 2 and the rotating rod 3 also move away from each other, so that the positioning ring 1 and the trimming ring 5 are separated.

[0036] After separation, the user moves the device until the ginkgo branches to be trimmed are located between the positioning ring 1 and the trimming ring 5. Then, the user moves the hand-held ring 4 towards each other, so that the positioning ring 1 and the trimming ring 5 are close to each other.

[0037] When the positioning ring 1 and the trimming ring 5 are in contact with the outer wall of the ginkgo branches and cannot continue to move, the user continues to force the hand-held ring 4 towards each other on the basis of starting the motor 67.

[0038] At this time, the motor 67 drives the lower sprocket 61 to rotate, so that the sprocket 61 drives the chain 62 to move, so that the chain 62 drives the trimming block 65 to move in the process of moving, so that the tip of the trimming block 65 can cut the ginkgo branches in the process of moving due to contact with the ginkgo branches, and the trimming block 65 can cut the ginkgo branches. At the same time, because the shape of the trimming block 65 is conical, the left side of the trimming block 65 can smoothly move towards the direction of the cut after cutting. At this time, the user is in a force state at the hand holding ring 4, so when the left side of the ginkgo tree produces a cut, the trimming ring 5 can immediately displace relative to the positioning ring 1, thereby driving the trimming block 65 to move towards the position where no cut is produced, until the branch is cut off.

[0039] Because the trimming block 65 is always in the middle position of the trimming ring 5 during trimming, it is not easy to contact the user, so as to ensure the safety of the user during use.

[0040] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
