The device comprises a handle, a spring, a rotation shaft, a moving circle, a fixed circle, a gear, a rack, a servo motor and a micro direct current motor, wherein the spring is firmly installed on the handle; the server motor drives rotation of the gear; the gear is meshed with the rack; the rack moves so as to drive the moving circle to be fixed on a branch of a pomelo tree; the handle is divided into two parts; the fixed circle is installed on the handle; two parts of the fixed circle are buckled into a whole circle; when the handle is opened or closed, the fixed circle will also be opened and closed under driving; a groove is formed in the fixed circle; a roller is embedded into the groove and rolls in the groove; a linkage rod passes through a center hole of the roller; the roller is rotated circumferentially; two pomelo tree girdling devices are connected by the linkage rod; a girdling handle is fixed on the linkage rod; a girdling cutter is disposed on one end of the girdling handle, and a linkage plate is disposed on the other end; and under manual assistance, the girdling cutter makes circular motion with a fixation point of the handle and the linkage rod as the circle center and with the distance from the fixation point to the girdling cutter tip as the radius so as to conduct girdling of the pomelo tree.

The invention relates to a braking energy feedback system. The braking energy feedback system comprises an industrial personal computer, an electro-hydraulic hybrid braking device and an energy feedback device, the industrial personal computer and the energy feedback device are both connected with the electro-hydraulic hybrid braking device. According to the braking energy feedback system, the electro-hydraulic hybrid braking device and the energy feedback device share the same motor structure, the reasonable distribution of braking force is completed, the distribution and utilization rate ofthe braking force is increased, and then the energy feedback benefit is increased; moreover, the electro-hydraulic hybrid braking device is adopted, the braking force distribution proportion can be optimized while the driving stability of an unmanned vehicle is improved, the electro-hydraulic hybrid braking device and the energy feedback device can obtain the optimal braking force distribution result, and then the electric energy conversion rate can be increased.
