Description

Technical Field

[0001] This utility model relates to the field of pruning shears, and in particular to a device for harvesting branches and leaves of the yew tree. Background Technology

[0002] The yew (also known as the purple yew) is a valuable medicinal plant. Its branches and leaves contain paclitaxel, an important raw material for anticancer drugs. However, the yew plant itself is poisonous. Care must be taken when harvesting branches and leaves. Clean, sharp pruning shears or cutting shears should be used to avoid pulling or damaging the trunk. Select healthy, disease-free branches and cut them to no more than one-third of their length, retaining enough leaves to sustain the tree's growth. Apply a plant wound sealant to the cut to prevent infection.

[0003] Currently, the scissors or pruning shears used in existing technologies have relatively simple structures, generally as shown in the instruction manual. Figure 1 As shown, the pruning shears include a first pruning assembly 01 and a second pruning assembly 02 arranged in a cutting manner. The first pruning assembly 01 includes a blade head 011 and a first handle 012, and the second pruning assembly 02 includes a bottom blade 021 and a second handle 022. However, this type of prior art cannot prevent sap splashing when pruning yew branches and leaves. Gloves, masks, and goggles need to be worn throughout the operation, but there are still blind spots in protection. Therefore, the existing pruning shears are not safe enough when used for picking yew branches and leaves.

[0004] In response to this, this application provides a yew branch and leaf harvesting device to solve the above-mentioned technical problems. Utility Model Content

The blade and the bottom blade cooperate to form a cutting mechanism, and the first handle and the second handle cooperate to form an operating handle mechanism. A protective cover is fixed in the middle of the first handle to separate the blade, and the bottom of the protective cover extends to the middle of the second handle, separating the second handle from the bottom blade.

[0008] Optionally, the bottom of the protective cover has a vertical movable groove, and the middle part of the second handle passes through the movable groove.

[0009] Optionally, a fixing cylinder for the first grip to pass through is fixed in the middle of the protective cover, and a plurality of fastening bolts are provided on the fixing cylinder.

[0010] Optionally, the fastening bolt passes through the fixing cylinder and the first handle, and is secured with a nut.

[0011] Optionally, a detachable cutting edge is inserted and installed at the end of the blade head, and a fixing pin is provided on the top back of the blade head to fix the detachable cutting edge.

[0012] Optionally, one end of the detachable cutting head is fixed with a plug block for insertion into the end of the cutting head, and the plug block has a fixing hole for the fixing pin to pass through vertically.

[0013] Optionally, the top end of the fixing pin is located outside the top back of the cutter head and is fixed with a screw cap.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above solution, thanks to the protective cover, the cutting mechanism and the operating handle mechanism can be separated, which can avoid the problem of sap splashing onto the skin of workers' hands when cutting yew branches and leaves to a certain extent. Compared with the existing technology, this device is safer to use.

[0016] In the above solution, thanks to the detachable cutting head, the cutting efficiency can be quickly maintained by replacing the detachable cutting head when the cutting head wears out after long-term use, making it convenient to use.

[0017] In summary, this device not only provides some protection against sap splashing from yew branches and leaves, but also facilitates blade replacement, ensuring cutting efficiency and overall good performance. Attached Figure Description
