[0020] Example: Figures 1-5 As shown, this utility model provides a multi-functional manual pruning shear for fruit trees, including pruning shears 1 and two extension rods 2. The pruning shears 1 are existing multi-functional manual pruning shears for fruit trees, used for pruning branches and grafting branches. Each of the two extension rods 2 includes a fixed rod 201, a sliding rod 202, and a handle 203. The two sliding rods 202 are slidably inserted into the corresponding fixed rods 201. The two handles 203 are fixedly installed at one end of the corresponding fixed rods 201. A threaded rod 9 is fixedly installed at one end of the handle of each pruning shear 1. The ends of the two sliding rods 202 away from the fixed rods 201 are provided with threaded holes 10, and the threaded rods 9 on the pruning shears 1 can be threaded into the threaded rods 202 of the corresponding sliding rods 202. Inside the perforated hole 10, one end of each of the two fixed rods 201 is threaded with a limiting bolt 3, and each of the two sliding rods 202 has a limiting hole 4. The bottom end of the limiting bolt 3 can be inserted into the corresponding limiting hole 4. When it is necessary to prune the branches at a high position, the extension rod 2 can be threaded onto the handle of the pruning shears 1 through the threaded hole 10 and the threaded rod 9. Then, depending on the height of the branches to be pruned, the position of the fixed rod 201 is slidably adjusted to adjust the length of the extension rod 2, and the limiting bolt 3 is tightened so that the bottom end of the limiting bolt 3 is inserted into the corresponding limiting hole 4 on the sliding rod 202 to fix the length of the extension rod 2, thereby achieving the purpose of facilitating the pruning of branches at a high position.
[0021] A clamp 7 is hinged to one handle of the pruning shears 1, and the clamp 7 can be fitted onto the other handle of the pruning shears 1. A slot 8 is provided on the handle of the pruning shears 1 without the clamp 7, and the clamp 7 can be locked into the slot 8.
[0022] By adopting the above technical solution, when the pruning shears 1 are not in use, the clamp 7 can be inserted into the groove 8 on the shear handle to limit the cutting edge of the pruning shears 1, preventing the cutting edge from opening and accidentally injuring the user.
[0023] The rotating rod 5 and the clamping block 6 are respectively hingedly installed on the two fixing rods 201.
[0024] By adopting the above technical scheme, when the pruning shears 1 are temporarily used after the extension rod 2 is installed, the rotating rod 5 can be clamped in the clamping block 6.
[0025] The sliding slot 12 is formed in the rotating rod 5, and the sliding block 13 is slidably installed in the sliding slot 12.
[0026] By adopting the above technical scheme, the sliding block 13 slides in the sliding slot 12.
[0027] The limiting rod 14 is fixedly installed at the top end of the sliding block 13, the limiting slot 11 is formed in the clamping block 6, and the limiting rod 14 can be clamped in the limiting slot 11.
[0028] By adopting the above technical scheme, the sliding block 13 drives the limiting rod 14 to slide along the sliding slot 12, and the limiting rod 14 is clamped into the limiting slot 11, thereby limiting the rotating rod 5.
[0029] The guide rod 15 is fixedly installed in the sliding slot 12, and the guide rod 15 penetrates and is inserted into the sliding block 13, the spring 16 is sleeved on the guide rod 15, and one end of the spring 16 is in contact with one side of the sliding block 13.
[0030] By adopting the above technical scheme, the limiting rod 14 is driven to slide along the guide rod 15 in the sliding slot 12, and the spring 16 is pressed, the limiting rod 14 is loosened, and the spring 16 is used to make the limiting rod 14 slide and be clamped into the limiting slot 11, thereby limiting the rotating rod 5.
[0031] Working principle: when the pruning shears 1 are used to prune trees and graft branches, when the pruning shears 1 are not used, the clamping block 7 is clamped into the clamping slot 8 on the handle of the pruning shears 1 to limit the blades of the pruning shears 1, prevent the blades from being opened and hurting the user, when it is necessary to prune the branches at a high position, the extension rod 2 is screwed on the handle of the pruning shears 1 through the threaded hole 10 and the threaded rod 9, then the position of the fixing rod 201 is adjusted according to the height of the branch to be pruned, the length of the extension rod 2 is adjusted, the limiting bolt 3 is tightened, the bottom end of the limiting bolt 3 is inserted into the corresponding limiting hole 4 in the sliding rod 202, and the length of the extension rod 2 is fixed, thereby achieving the purpose of conveniently pruning the branches at a high position.
[0032] When the extension rod 2 is temporarily used and the pruning shears 1 is installed, the limiting rod 14 is pulled to drive the sliding block 13 to slide along the guide rod 15 in the sliding groove 12 and press the spring 16, then the rotating rod 5 is rotated and clamped in the clamping block 6, then the limiting rod 14 is released, the spring 16 is rebounded to make the limiting rod 14 slide and clamp into the limiting groove 11, the rotating rod 5 is limited, the pruning shears 1 is closed and limited, the cutting blades are prevented from opening and hurting the user.
[0033] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
