In order to achieve the above object, the utility model is achieved through the following technical solutions: a branch pruning device, including a telescopic support and a cutting mechanism, the support includes an upper and a lower support, and the upper support is arranged on the lower support through a The electric telescopic mechanism can move up and down along the length direction of the lower support, and the cutting mechanism includes a cutting motor arranged on the upper end of the upper support and a cutting disc arranged on the output shaft of the cutting motor.

Further, the electric telescopic mechanism includes driving and driven wheels respectively arranged at both ends of the lower bracket, a transmission member connecting the driving and driven wheels, and a telescopic motor that drives the driving wheel to rotate. The lower end of the upper bracket is connected to the The connecting piece on the transmission part is connected, and a guide groove is provided on the upper end of the lower bracket, and the upper bracket is sleeved in the guide groove, and moves up and down driven by the transmission part.

Further, a control switch for controlling the start and stop of the cutting motor and the telescopic motor is arranged on the lower bracket.

Further, it also includes a support sheet hingedly arranged at the lower end of the lower bracket that can be attached to the waist and abdomen of the human body, and shoulder straps that are arranged on both sides of the lower bracket and can be hung on the shoulders of the human body.

Further, the transmission member is a transmission belt.

Further, the telescopic motor is arranged at the lower end of the lower bracket.

Beneficial effects of the utility model: a branch pruning device of the utility model includes a telescopic bracket and a cutting mechanism, the bracket includes an upper bracket and a lower bracket, and the upper bracket can be moved along the The lower bracket moves up and down in the length direction, and the cutting mechanism includes a cutting motor arranged on the upper end of the upper bracket and a cutting disk arranged on the output shaft of the cutting motor. The branch pruning device of the structure has the advantages of being able to safely, conveniently and easily prune high branches.

detailed description

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

Please refer to Fig. 1-3, the utility model provides a kind of technical solution: a kind of branch pruning device, comprises telescopic support 1 and cutting mechanism 3, and described support 1 comprises upper and lower support 12, 11, and described upper support 12 The electric telescopic mechanism 2 arranged on the lower bracket 11 can move up and down along the length direction of the lower bracket 11. Specifically, the electric telescopic mechanism 2 includes driving and driven wheels 22, 24 respectively arranged at both ends of the lower bracket 11, connecting the The transmission part 23 of the main and driven wheels 22, 24 and the telescopic motor 21 that drives the rotation of the driving wheel 22, the transmission part 23 can be a transmission chain or a transmission belt or other transmission components, in order to reduce the weight of the electric telescopic mechanism 2, the transmission The part 23 adopts a transmission belt. In order to save effort when using, the telescopic motor 21 is arranged on the lower end of the lower bracket 11, and the lower end of the upper bracket 12 is connected with the connecting piece 4 arranged on the transmission part 23. Guide groove 111, upper support 12 is sleeved in described guide groove 111, and moves up and down under the drive of transmission member 23, described cutting mechanism 3 comprises the cutting motor 31 that is arranged on the upper end of upper support 12 and is arranged on described cutting motor Cutting disc 32 on the 31 output shaft. When using the branch pruning device of this structure, the operator first starts the telescopic motor 21, adjusts the support 1 to a suitable length, and after closing the telescopic motor 21, starts the cutting motor 31 again, so as to trim the high branches. It is only necessary for the operator to hold the branch pruning device, which is safe and convenient. Of course, in order to control the start and stop of the cutting motor 31 and the telescopic motor 21 conveniently, a control switch 5 is provided on the lower bracket 11 .

As a further improvement of the above scheme, it also includes a support piece 6 that is hingedly arranged at the lower end of the lower bracket 11 and can be fitted to the waist and abdomen of the human body and a shoulder strap 7 that can be hung on the shoulders of the human body on both sides of the lower bracket 11. The weight of the device is relatively heavy, and if it is held by hand for a long time, the operator will feel very tired. Therefore, the weight of the branch pruning device is distributed to the operator's shoulders by the shoulder strap 7. At the same time, the support sheet 6 is attached to the operator's shoulders. The waist and abdomen provide a comfortable support point for wearing the branch pruning device.

The basic principles and main features of the utility model and the advantages of the utility model have been shown and described above. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the utility model The present utility model can be realized in other specific forms without the spirit or essential features. Therefore, no matter from all points of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to fall within the scope of the claims All changes within the meaning and range of equivalents of the required elements are included in the present invention. Any reference sign in a claim should not be construed as limiting the claim concerned.
