[0001] The utility model belongs to the technical field of pruning devices, and in particular relates to a portable kiwifruit pruning device. Background Art

[0002] In order to promote the healthy growth of kiwifruit trees and increase fruit yield, the branches of kiwifruit trees need to be pruned regularly. This work is generally done with pruning shears. However, the handle lengths of existing kiwifruit pruning shears are fixed, and the handle lengths cannot be adjusted according to pruning requirements, making it difficult to meet usage requirements. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a portable kiwifruit pruner, which can conveniently extend and fold the handle part and conveniently disassemble the telescopic handle to meet different usage requirements.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: a portable kiwifruit pruner comprises a first shearing body and a second shearing body, the first shearing body and the second shearing body are connected by a pin shaft, a first spring is connected between the first shearing body and the second shearing body, one end of the first shearing body and the second shearing body are connected to a main grip, a first spring accommodating cavity is provided on the inner side of the main grip, an insertion groove is provided on one side of the main grip, the insertion groove is inserted and connected with a limiting arc plate, a telescopic grip is slidably inserted into the inner side of the main grip, a limiting plate is provided on one end side of the telescopic grip, a second spring accommodating cavity is provided on one end of the telescopic grip, a second spring is provided on the inner sides of the first spring accommodating cavity and the second spring accommodating cavity, one end of the telescopic grip is connected to a terminal grip, a sliding groove is provided on the inner sides of the terminal grip and the telescopic grip, a slidable connecting rod is provided on the inner side of the sliding groove, two ends of the connecting rod are respectively connected to a dial button and a limiting block, and a third spring is provided on the inner side of the sliding groove.

[0005] The beneficial effects of the utility model are as follows: when it is necessary to cut branches that are higher or farther away, the dial button is turned to drive the connecting rod and the limit block to slide, so that the limit block is separated from the limit between the limit arc plate. At this time, under the elastic force of the second spring, the telescopic grip rod automatically extends outward along the inner side of the main grip rod until the limit plate and the limit arc plate abut against each other, thereby effectively extending the gripping part of the device. At this time, the end grip handle is held, and the higher and farther branches can be conveniently pruned. After pruning is completed, the telescopic grip rod can be retracted and folded again, and the telescopic grip rod can be pressed into the inside of the main grip rod again. When the inclined surface on the limit block contacts the side surface of the limit arc plate, the inclined surface is used to make the telescopic grip rod extend outward along the inner side of the main grip rod. The limit block is pressed into the inner side of the telescopic grip and compresses the third spring. When the limit block passes over the limit arc plate, the limit block pops out again under the action of the rebound force of the third spring, and cooperates with the limit arc plate to limit the telescopic grip, so that the telescopic grip will not be popped out. At this time, the entire grip part maintains a shorter length, which is convenient for carrying and pruning lower and closer branches. When the telescopic grip needs to be disassembled, unscrew the locking screw, remove the limit arc plate, the telescopic grip can be taken out, and the first spring can be taken out. The operation is very convenient. In summary, the device can conveniently extend and fold the grip part, and facilitate the disassembly of the telescopic grip to meet different usage requirements.

[0007] As a further improvement of the above technical solution: a first spring sleeve rod is provided inside the first spring accommodating cavity, a second spring sleeve rod is provided inside the second spring accommodating cavity, and the second spring is sleeved outside the first spring sleeve rod and the second spring sleeve rod.

[0008] The beneficial effect of this improvement is that the first spring sleeve rod and the second spring sleeve rod are used to assist in fixing the two ends of the second spring.

[0009] In order to fix the insertion slot and the limiting arc plate:

[0010] As a further improvement of the above technical solution: a locking screw is threadedly connected between the insertion groove and the limiting arc plate.

[0011] The beneficial effect of this improvement is that the locking screw is used to fix the insertion slot and the limiting arc plate.

[0012] To facilitate the toggle button:

[0013] As a further improvement of the above technical solution: the top of the dial button is provided with anti-slip grooves.

[0014] The beneficial effect of this improvement is that the anti-slip pattern is used to increase the friction between the dial button and the user's fingers, thereby making it easier to turn the dial button.

[0015] To make it easier to refold the telescopic handle:

[0016] As a further improvement of the above technical solution: one side surface of the limit block is an inclined surface.

[0017] The beneficial effect of this improvement is as follows: in the process of pressing the telescopic grip rod back into the main grip rod, when the inclined surface on the limit block contacts the side surface of the limit arc plate, the limit block is pressed into the inner side of the telescopic grip rod through the inclined surface and compresses the third spring; when the limit block passes over the limit arc plate, the limit block pops out again under the action of the rebound force of the third spring, and cooperates with the limit arc plate to limit the telescopic grip rod, thereby improving the convenience of folding the telescopic grip rod again.

A limit plate 11 is provided on the side of one end of the telescopic grip 10, a second spring accommodating chamber 12 is provided at one end of the telescopic grip 10, a second spring 14 is provided inside the first spring accommodating chamber 5 and the second spring accommodating chamber 12, one end of the telescopic grip 10 is connected to the end handle 15, a sliding groove 16 is provided inside the end handle 15 and the telescopic grip 10, a slidable connecting rod 18 is provided inside the sliding groove 16, both ends of the connecting rod 18 are respectively connected to a dial button 17 and a limit block 19, and a third spring 20 is provided inside the sliding groove 16.

[0027] When it is necessary to cut branches that are higher and farther away, the dial button 17 is turned to drive the connecting rod 18 and the limit block 19 to slide, so that the limit block 19 is separated from the limit between the limit arc plate 8. At this time, under the elastic force of the second spring 14, the telescopic grip 10 automatically extends outward along the inner side of the main grip 4 until the limit plate 11 and the limit arc plate 8 are against each other, thereby effectively extending the gripping part of the device. At this time, holding the end handle 15, it is convenient to trim higher and farther branches. After trimming is completed, the telescopic grip 10 can be retracted and folded again, and the telescopic grip 10 can be pressed into the inside of the main grip 4 again. When the inclined surface on the limit block 19 When it contacts the side of the limiting arc plate 8, the limiting block 19 is pressed into the inner side of the telescopic grip 10 through the inclined surface and compresses the third spring 20. When the limiting block 19 passes over the limiting arc plate 8, under the action of the rebound force of the third spring 20, the limiting block 19 pops out again and cooperates with the limiting arc plate 8 to limit the telescopic grip 10, so that the telescopic grip 10 will not be popped out. At this time, the entire grip part maintains a shorter length, which is convenient for carrying and pruning lower and closer branches. When the telescopic grip 10 needs to be disassembled, unscrew the locking screw 9, remove the limiting arc plate 8, and then the telescopic grip 10 can be taken out and the first spring 3 can be taken out. The operation is very convenient.

[0028] A first spring sleeve rod 6 is disposed inside the first spring accommodating chamber 5 , a second spring sleeve rod 13 is disposed inside the second spring accommodating chamber 12 , and the second spring 14 is sleeved outside the first spring sleeve rod 6 and the second spring sleeve rod 13 .

[0029] The first spring sleeve rod 6 and the second spring sleeve rod 13 are used to assist in fixing the two ends of the second spring 14 .

[0030] A locking screw 9 is threadedly connected between the insertion groove 7 and the limiting arc plate 8.

[0031] The locking screw 9 is used to fix the insertion slot 7 and the limiting arc plate 8.

[0032] The top of the dial button 17 is provided with anti-slip grooves.

[0033] The anti-slip pattern is used to increase the friction between the dial button 17 and the user's fingers, thereby facilitating the movement of the dial button 17 .

[0034] One side surface of the limiting block 19 is an inclined surface.

[0035] During the process of pressing the telescopic grip 10 back into the main grip 4, when the inclined surface on the limit block 19 contacts the side of the limit arc plate 8, the limit block 19 is pressed into the inner side of the telescopic grip 10 through the inclined surface and compresses the third spring 20. When the limit block 19 passes over the limit arc plate 8, under the action of the rebound force of the third spring 20, the limit block 19 pops out again and cooperates with the limit arc plate 8 to limit the telescopic grip 10, thereby improving the convenience of folding the telescopic grip 10 again.

[0036] The working principle and use process of the utility model are as follows: when the device is used, the main grip 4 is held, and the first shear body 1 and the second shear body 2 can be driven to perform shearing action by pressing the main grip 4 inwardly, and the pressure on the main grip 4 is released. Under the action of the rebound force of the first spring 3, the first shear body 1 and the second shear body 2 can be automatically reset to the open state. When it is necessary to shear branches at higher and farther positions, the dial button 17 is turned to drive the connecting rod 18 and the limit block 19 to slide, so that the limit block 19 is separated from the limit between the limit arc plate 8. At this time, under the elastic force of the second spring 14, the telescopic grip 10 automatically extends outward along the inner side of the main grip 4 until the limit plate 11 and the limit arc plate 8 are against each other, thereby effectively extending the gripping part of the device. At this time, the end grip 15 is held, and higher and farther branches can be conveniently pruned. After pruning is completed, the telescopic grip 10 can be retracted and folded again, and the telescopic grip 10 can be pressed into the inside of the main grip 4 again. When the inclined surface on the limit block 19 contacts the side of the limit arc plate 8, the limit block 19 is pressed into the inner side of the telescopic grip 10 through the inclined surface and compresses the third spring 20. When the limit block 19 passes over the limit arc plate 8, under the action of the rebound force of the third spring 20, the limit block 19 pops out again, and cooperates with the limit arc plate 8 to limit the telescopic grip 10, so that the telescopic grip 10 will not be popped out. At this time, the entire grip part maintains a shorter length, which is convenient for carrying and pruning lower and closer branches. When the telescopic grip 10 needs to be disassembled, unscrew the locking screw 9, remove the limit arc plate 8, and then the telescopic grip 10 can be taken out and the first spring 3 can be taken out. The operation is very convenient.
