Examples

Referring to fig. 1-3, a length-adjustable branch pruning device comprises a grab handle 1 and an electric scissor head 4, wherein one end of the grab handle 1 is fixedly connected with a first pipe body 2, a second pipe body 3 is inserted into the first pipe body 2, the second pipe body 3 is slidably connected with the inner side wall of the first pipe body 2, the electric scissor head 4 is fixedly arranged at one end, far away from the grab handle 1, of the second pipe body 3, and the inner side of the grab handle 1 is fixedly provided with

The portion fixed mounting has motor 5, motor 5's output shaft fixedly connected with screw rod 6, the 5 terminal of screw rod 6 runs through the lateral wall of grab handle 1 and extends to the inside of second body 3, the one end that second body 3 is close to grab handle 1 is fixed to be provided with fixed block 7, screw rod 6 runs through fixed block 7 and with fixed block 7 threaded connection, be provided with limit structure between the lateral wall of first body 2 and second body 3, limit structure is including seting up the spacing spout 8 on the lateral wall of second body 3, the fixed spacing chimb 9 that is provided with on the inside wall of first body 2, spacing chimb 9 sliding connection is on the inside wall of spacing spout 0 8. The length direction of the limiting chute 8 and the limiting convex edge 9 is parallel to the central axes of the first pipe body 2 and the second pipe body 3.

The outer side wall of the grab handle 1 is also provided with an integrated switch 11 for controlling the start and stop of the electric scissor head 4 and the forward and reverse rotation of the motor 5. The side wall of the electric scissor head 4 is fixedly connected with a wire 10 with a certain length, the tail end of the wire 10 is fixedly connected to the side wall of the grab handle 1, the inner 5 part of the grab handle 1 is provided with a storage battery 12 for supplying power to the electric scissor head 4 and the motor 5, and the electric scissor head 4 can be powered through the wire 10.

Referring to fig. 1 and 4, a jack 13 is provided on a side wall of the end of the second tube body 3 far away from the grab handle 1 in a penetrating way, a plug rod 14 is inserted in the jack 13, and a plug rod 14 is fixed on the side wall of the plug rod 14

A plurality of inclined slide bars 15 are connected, and the slide bars 15 are parallel to each other. The insert rod 14 and the slide rod 15 can be made of light materials, such as plastics or aluminum alloy, so that the overall weight of the device is reduced. And the slide bar 15 can be as much as possible to provide a sufficiently large support surface for the fallen shoots. The cross-sectional shapes of the insertion hole 13 and the insertion rod 14 are rectangular, and the insertion rod 14 is attached to the inner wall of the insertion hole 13.
