Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. In the embodiment of the utility model, the section lines of different types in the drawing are not marked according to national standards, do not require the material of the element, and distinguish the section view of the element in the drawing.
Referring to fig. 1-2, a pair of pneumatic retractable garden shears is shown, which is a device consisting of a retractable rod and shears. When the switch is opened, the length of the telescopic rod is adjusted through the telescopic switch, and the branches are cut through the scissors under the control of the cutting switch. Specifically, a pneumatic scalable gardens are cut, including telescopic link 1, scissors 2 and dwang 6, its characterized in that: telescopic link 1 includes first pars contractilis 11 and second pars contractilis 13, first pars contractilis 11 and second pars contractilis 13 are through first cylinder 12 fixed connection, 1 lower extreme of telescopic link is provided with control switch 5, control switch 5 includes switch 51, telescopic switch 52 and shear switch 53 one end are connected with the power, be connected with the tribit five-way solenoid valve through the power, later even return to the other end of switch, can control the tribit five-way solenoid valve through control telescopic switch 52 like this, thereby change the length of telescopic link 1 and prune not the branch of co-altitude. The upper end of the telescopic rod 1 is rotatably connected with a rotating rod 6 through a nylon rotating shaft 4, and the angle of the rotating rod can be changed in such a connecting mode, so that the shearing process is more convenient. 1 dwang 6 of telescopic link is hollow pole, dwang 6 right-hand member outside symmetry is provided with support frame 9, dwang 6 passes through support frame 9 and 23 fixed connection of axis of rotation, the fixed second cylinder 7 that is provided with on dwang 6, piston 71 on the second cylinder 7 is connected with handle of a knife 22 through connecting rod 8, connecting rod 8 is connected for rotating with the connected mode of piston 71 and handle of a knife 22, thereby control second cylinder 7 through control shear switch 53, the motion that can control scissors 2 through piston 71 on the second cylinder 7 is used for pruning the branch, make operating personnel more laborsaving at the shearing in-process. The speed regulating valve 3 is arranged at the air inlet and outlet of the second air cylinder 7, and the cutting speed can be changed by regulating the speed regulating valve 3.
