Description
Technical Field
[0001] The utility model relates to the technical field of trimmers, in particular to a trimming tool for thinning fruits of apricot plum trees which is convenient to operate. Background Technique
[0002] In the cultivation and management of apricot plum, fruit thinning is a crucial step. It helps to promote the growth and development of fruits, improve the quality, and at the same time prevent biennial bearing, achieving high and stable yields. Compared with flower thinning, the effect of fruit thinning is more significant. Generally, a trimmer consists of a rotating rod, an upper scissor, a lower scissor, and a spring. Generally, the upper scissor and the lower scissor are held, and the two are squeezed through the rotating rod to trim the branches of some apricot plums among a large number of apricot plums.
[0003] The above-mentioned and existing related technologies often have the following defects: During the process of thinning fruits of apricot plum trees, there are many fruits on a single branch. Personnel need to trim some of the apricot plums to reduce the number of apricot plums on a single branch for fruit thinning. When trimming the branches, generally, the upper scissor and the lower scissor are held, and the two are squeezed through the rotating rod to trim the branches of some apricot plums among a large number of apricot plums. After trimming, the upper scissor and the lower scissor are reset by means of a compression spring. Therefore, personnel need to insert the blade into the space between multiple apricot plums to trim the branches. However, when using the way of holding the upper scissor and the lower scissor, for some people with smaller palms, the opening angle of the compression spring is too large. Therefore, it is difficult for personnel to hold the upper scissor and the lower scissor as a whole. This not only causes the lower scissor to fall off from the hand during the trimming process, but also makes it difficult to squeeze the lower scissor due to the elastic force of the compression spring itself, and it is difficult to accurately move to the position of the branch inside the apricot plum for trimming, which is not conducive to the fine operation of workers and may lead to the problem that the branches cannot be trimmed.
[0004] Therefore, we propose a trimming tool for thinning fruits of apricot plum trees which is convenient to operate. Content of the Utility Model

[0029] 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 in 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.
[0030] Please refer to Figure 1 , the present utility model provides a technical solution: a pruning tool for thinning fruits of apricot-plum trees that is easy to operate, including a rotating rod 1. The arc surface of the rotating rod 1 is rotatably connected to an upper scissor 2. The position of the arc surface of the rotating rod 1 relative to the upper scissor 2 is rotatably connected to a lower scissor 3. The surface of the lower scissor 3 is fixedly connected to a spring 4, and the other end of the spring 4 is fixedly connected to the upper scissor 2. A limiting structure 5 is provided on the surface of the lower scissor 3, achieving the effect of limiting between the upper scissor 2 and the lower scissor 3 for thinning branches of apricot-plum trees and the human hand, thereby minimizing the problem that the opening and closing angle between the upper scissor 2 and the lower scissor 3 is too large, making it difficult for people with small palms to hold and apply force to prune branches. A protective structure 6 is provided on one side of the lower scissor 3. The effects achieved by the above components are: achieving the effect of protecting the position of the tool head, so that the tool head is wrapped inside during the process of taking the pruning tool, avoiding accidental contact with people or objects and causing certain damage, thereby improving the service life of the device.
[0031] Next, the specific settings and functions of its limiting structure 5 and protective structure 6 will be specifically described.
[0032] As Figure 2 and Figure 3 and Figure 4As shown, the limit structure 5 includes two circular sleeves 501. The arc surfaces of the two circular sleeves 501 are fixedly connected to the lower scissors 3. A fixed frame 502 is fixedly connected to the arc surfaces of the two circular sleeves 501. A long rod 503 is slidably connected to the inner wall of the fixed frame 502. A sliding hole 504 is formed in the surface of the lower scissors 3 at a position between the two circular sleeves 501. The arc surface of the long rod 503 is slidably connected to the inner wall of the sliding hole 504. An enlarged hole 505 is formed in the surface of the upper scissors 2. The arc surface of the long rod 503 is slidably connected to the inner wall of the enlarged hole 505. A screw rod 506 is threadedly penetrated through one side of the upper scissors 2 at a position relative to the enlarged hole 505. A limit hole 507 is formed in the arc surface of the long rod 503. The arc surface of the screw rod 506 is slidably connected to the inner wall of the limit hole 507. By rotating the screw rod 506, it is inserted into the limit hole 507 through the upper scissors 2, and the screw rod 506 plays a role in temporarily limiting the closing of the lower scissors 3. The upper end of the long rod 503 is rotatably connected to a placement plate 508. The placement plate 508 is an arc plate. When the palm is placed on the placement plate 508, a better fit between the person and the long rod 503 is achieved through the rotatable placement plate 508. Limit blocks 509 are fixedly connected to the inner walls of the two circular sleeves 501. The limit blocks 509 are silicone blocks. When the fingers are inserted into the circular sleeves 501 and fit with the limit blocks 509, the limit blocks 509 play a role in further holding for thin-fingered personnel. A circular block 510 is fixedly connected to the lower end of the long rod 503. The arc surface of the circular block 510 is slidably connected to the inner wall of the sliding hole 504. The long rod 503 drives the circular block 510 to slide from the inner wall of the sliding hole 504, and the circular block 510 achieves the effect of assisting the long rod 503 to be guided into the sliding hole 504.
[0033] As Figure 3 and Figure 5 shown, the protection structure 6 includes a fixed rod 61. One end of the fixed rod 61 is fixedly connected to the lower scissors 3. A circular plate 62 is fixedly connected to the end of the fixed rod 61 away from the lower scissors 3. A rotating ring 63 is rotatably connected to the arc surface of the fixed rod 61. A connecting rope 64 is fixedly connected to the arc surface of the rotating ring 63. The other end of the connecting rope 64 is fixedly connected to a protective sleeve 65. The connecting rope 64 is a pull rope, and the protective sleeve 65 is a rubber sleeve. The rubber sleeve-like protective sleeve 65 plays a role in preventing hard contact with the blade tip of the upper scissors 2.
[0034] Working principle: When pruning and thinning the branches and fruits of apricot plum trees, first remove the protective structure 6 and disengage it from the cutting edges of the upper scissors 2 and the lower scissors 3. Then, rotate the screw rod 506 through the upper scissors 2 to the side away from the long rod 503. The screw rod 506 disengages from the inner wall of the arc surface limit hole 507 of the long rod 503. The screw rod 506 plays a role in temporarily limiting the retraction of the lower scissors 3. At this time, the spring 4 is in an open state. Drive the lower scissors 3 to rotate and unfold through the upper scissors 2 with the help of the rotating rod 1. At this time, the upper scissors 2 and the lower scissors 3 are opened. Then, the person inserts their finger into the round sleeve 501 and fits it with the limit block 509. The limit block 509 plays a role in further holding the person with thinner fingers. The palm fits with the inner wall of the placement plate 508. By means of the rotatable placement plate 508, a better fit between the person and the long rod 503 is achieved. Then, drive the lower scissors 3 to move into multiple apricot plum fruits on a single branch through the round sleeve 501. After positioning the pruning position of the branch of the inferior apricot plum fruits, pull the round sleeve 501. The lower scissors 3 drive the upper scissors 2 to lift through the round sleeve 501 with the help of the rotating rod 1. The long rod 503 slides from the inner wall of the enlarged hole 505. At this time, the upper scissors 2 fit with the lower surface of the placement plate 508. After continuously pulling the round sleeve 501, the fixed frame 502 slides from the arc surface of the long rod 503, and then slides through the round block 510 from the inner wall of the sliding hole 504. The round block 510 achieves the effect of assisting the long rod 503 to guide into the sliding hole 504, making the upper scissors 2 and the lower scissors 3 approach each other. As a result, the spring 4 is in a compressed state at this time. The approaching upper scissors 2 and lower scissors 3 use the rotating rod 1 to make the cutting edges prune the branches and fruits of the apricot plum tree, thereby reducing the number of apricot plum fruits on a single branch. After the pruning is completed, loosen the finger slightly. At this time, the spring 4 is in an open state. Drive the lower scissors 3 to move away from each other through the upper scissors 2. The round sleeve 501 drives the fixed frame 502 to slide from the arc surface of the long rod 503 through the lower scissors 3. The long rod 503 drives the round block 510 to disengage from the inner wall of the sliding hole 504, thus completing the pruning of the branch. Repeating the above operations can continue to prune other branches. And through the mutual extrusion and approach of the round sleeve 501 and the placement plate 508, people with smaller hands can also hold the upper scissors 2 and the lower scissors 3 as a whole, facilitating the pruning operation of the fruit-thinning branches of apricot plum trees by different people.
[0035] When it is necessary to disengage the protective sleeve 65 from the cutting edges of the upper scissors 2 and the lower scissors 3, pull the protective sleeve 65 to disengage it from the cutting edge of the upper scissors 2. The protective sleeve 65, which is a rubber sleeve, plays a role in avoiding hard contact with the cutting edge of the upper scissors 2. At this time, the connecting rope 64 is in a stretched state due to the movement of the protective sleeve 65. After the protective sleeve 65 is disengaged from the cutting edge of the upper scissors 2 and then released, the connecting rope 64 is in a contracted state. Straighten the protective sleeve 65 below the lower scissors 3 with the help of the rotating ring 63. The rotating ring 63 rotates from one side of the round plate 62 on the arc surface of the fixed rod 61, so that pruning of the branch can be carried out through the upper scissors 2 and the lower scissors 3.
