[0002] Coffee shade trees in the tableland refer to a type of trees specially configured and planted in coffee plantations in the tableland to provide moderate shade for the growth of coffee trees. The main purpose is to regulate the microenvironment of the coffee plantation and ensure the healthy growth and fruit quality of the coffee trees. The fixing device for shaping and pruning of coffee shade trees in the tableland is a special agricultural tool designed for the shaping and pruning of shade trees in coffee plantations. Its core function is to fix the angle of branches and support the posture of the trunk during pruning, thereby assisting in shaping and controlling the growth of the tree. It mainly creates a suitable shade and ventilation environment for the coffee trees below, ensuring the yield and quality of coffee. For example, in the prior art 1 (Chinese patent with application number CN202323296941.8 and application date of December 5, 2023), a beech tree trunk shaping device is installed with a beech tree trunk locking rope on each set of sliding grooves. This design can better fix the beech tree trunk, allowing it to remain stable during growth. The adjustable support is connected between the rotating top seat and the rotating clamping seat installed on the top, allowing the inclination angle of the beech tree trunk shaping horizontal frame to be adjusted. The adjustable support has a plurality of evenly spaced vertical limiting insertion holes on its outer wall, which can easily adjust the height of the beech tree trunk shaping horizontal frame. The limiting pin can limit the adjustable support, improving stability. In the prior art 2 (Chinese patent with application number CN202022738650.X and application date of November 24, 2020), a milk fruit tree shaping device is provided. The bottom rod with clamping jaws can fix the left and right supports from top to bottom. The bottom rod has an angle-adjustable connecting rod and a fixed rod on the upper side. The first and second fixed rings and the fixed hole can be used to fix the traction rope. The traction rope can be used to pull the branches of the fruit tree from different directions, thereby completing the shaping work of the fruit tree.
