Description

Technical Field

[0001] The utility model relates to the field of fruit tree pruning, in particular to a fruit tree pruning device with an adjusting function. Background Art

[0002] Fruit trees, trees with edible fruits, refer to perennial plants and their rootstocks that can provide edible fruits and seeds. Fruit tree pruning refers to the technical measures of cutting off part of the vegetative organs of fruit trees to adjust the crown structure and renew the branch composition;

[0003] Fruit tree pruning is conducive to regulating the reasonable distribution of branches and leaves, growth and fruiting, and the proportion of branch composition. It can also balance the growth potential between groups of plants and between the main branches on a plant, so as to achieve balanced yield and facilitate management. In addition, it is also a means to coordinate the growth of the aboveground part and the root system. After searching, the Chinese patent announcement number: CN218184163U discloses a fruit tree pruning device. The front end of the fixed rod is equipped with a sickle head, and the rear end of the fixed rod is provided with a handle. A buckle plate is hinged in the handle. A telescopic spring is connected between the handle and the buckle plate. The rotating column at the top of the buckle plate is provided with multiple tooth grooves along the cylindrical surface. A tooth row, a connecting rod and a cutting knife are installed in the long slot hole on one side of the fixed rod. The tooth row is connected to the cutting knife through the connecting rod. The tooth row and the tooth groove are in conflict and mesh, and a certain distance is maintained between the cutting knife and the sickle head. The pruning device can be operated by holding the handle, and the tooth row can be driven to move forward by depressing the buckle plate. The cutting knife moves forward and approaches the sickle head. The cutting knife and the sickle head can be used to cut off the branches of the fruit tree. Compared with the existing compact pruning pliers, the fixing rod of the pruning device of the utility model has a certain length. When pruning branches while standing on the ladder, there is no need to move the ladder frequently, which can effectively improve the efficiency of pruning branches.
