The invention provides a manpower-assisted handheld electric pomelo tree girdling device for clamping branches with different diameters. The device comprises hand grips, a spring, a rotary shaft, clamping blocks, a steady circle and a direct current micro-motor. The spring is fixedly arranged on the hand grips, during the work, the acting force of the spring makes the clamping blocks firmly fixed to a branch of a pomelo tree so as to prevent the branch from rotating along with a girdling knife, the hand grips are divided into two parts, the steady circle installed on the hand grips, the two parts of the steady circle are buckled together to form a whole circle, and the steady circle is opened and closed along with the opening and closing of the hand grips. Grooves are formed in the steady circle, idler wheels are embedded into the grooves and rotate in the grooves, a link bar penetrates through center holes of the idler wheels and the idler wheels do circular movement. Two pomelo tree girdling devices are connected together through the link bar, a girdling handle is fixed to the link bar, one end of the girdling handle is provided with the girdling knife, and the other end of the girdling handle is provided with a link plate. Under the manpower assistance, the girdling knife does circular movement with the fixed point of the hand grips and the link bar as the center and the distance from the fixed point to the point of the girdling knife as the radius so as to conduct girdling on the pomelo tree.

The invention provides an artificial auxiliary handheld electric persimmon tree girdling device for clamping a variable-diameter branch. The artificial auxiliary handheld electric persimmon tree girdling device for clamping the variable-diameter branch comprises a handle, a spring, a rotation shaft, a clamping block, a fixed circle and a minitype direct current motor. The handle is fixedly provided with the spring. In the operation process, the clamping block is fixed on the branch of the persimmon tree by the acting force of the spring, and is prevented to be rotated along with a girdling blade. The handle is divided to two parts. The fixed circle is installed on the handle. Two parts of the fixed circle are closed to form a whole circle. The fixed circle is opened and closed along with the open and close of the handle. The fixed circle is provided with a groove. A roller is embedded in the groove and is rolled in the groove. A linkage rod passes through the central hole of the roller. The roller is rotated around the circumference. Two persimmon tree girdling devices are connected by the linkage rod. A girdling handle is fixed on the linkage rod. One end of the girdling handle is provided with the girdling blade, and the other end is provided with a linkage plate. Under the drive of the power, the girdling blade is circumferentially moved by using the fixed point of the handle and the linkage rod as the center, and using the distance from the fixed point to the point of the girdling blade as the radius, for girdling the persimmon tree.

The invention provides a manually assisted hand-held electric winter jujube girdler for clamping branches with variable diameters, including a handle, a spring, a rotating shaft, a clamping block, a fixed circle and a micro DC motor, and a spring is fixedly installed on the handle. During operation, the spring The force will fix the clamping block on the branch of Dongzao to prevent it from rotating with the ringing knife. The handle is divided into two parts. The fixed circle is installed on the handle. The two parts of the fixed circle are buckled together to form a complete circle. The handle When it opens and closes, the fixed circle also opens and closes accordingly. There is a groove on the fixed circle, and the roller is embedded in the groove and rolls in the groove. The link passes through the center hole of the roller, and the roller rotates in a circle. Connect two winter jujube girdling devices together, the girdling handle is fixed on the connecting rod, one end of the girdling handle is provided with a girdling knife, and the other end is provided with a connecting plate, driven by power, the girdling knife is connected with the handle and The fixed point of the connecting rod is the center of the circle, and the radius of the knife tip from the fixed point to the girdling knife is used as a circular motion to girdling the winter jujube.
