[0012] Preferably: the plug-in is connected to the limiting square member, a spring is sleeved on the cross bar member, and the spring is connected between the block member and the shell member, the shell member is in sliding contact with the block member through a slide groove, the handle sleeve is connected to the threaded rod through a thread, and the end of the operating handle is provided with anti-slip texture.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This kind of branch pruning device for forestry engineering is provided with an operating handle component group. The current branch pruning shears are designed with a long operating handle for labor-saving purpose because they are used to prune thick branches. However, this very long operating handle will make the overall branch pruning shears larger in size, and it will take up a larger volume when carried, which reduces portability. In the corresponding designed operating handle component group, when the branch pruning shears component group and the operating handle component group need to be carried, the pull handle in the operating handle component group can be pulled to move in the direction away from the plug-in. The movement of the pull handle will drive the cross bar and the card block to move, and the spring on the cross bar will accumulate force and contract, and the card block will release the contact with the card slot of the plug-in. At this time, the limit square member and the plug-in can be pulled out of the housing member, and then the separation is completed, which reduces the overall volume and can be carried separately or stacked for carrying, thereby achieving the effect of improving portability, and the control of the operating handle end and With this overall design, the operating handle of the branch pruning shears can be easily disassembled and shortened when not in use, which greatly reduces the space occupied when carrying and improves portability.

[0015] 2. This branch pruning device for forestry engineering is provided with an operating handle component group, and the designed limiting square member is also inserted into the shell member. The limiting square member is used to improve the connection strength between the handle sleeve and the shell member, and ensure the structural strength of the overall operating handle component group when the clamping block is limited by the plug-in groove.

[0024] There are two groups of operating handle component groups 02, and the two groups of operating handle component groups 02 are symmetrically arranged on one side of the scissors blade 11 and the scissors blade 2 12. The connecting disk 21 in one group of operating handle component groups 02 is connected to the scissors blade 11, and the connecting disk 21 in the other group of operating handle component groups 02 is connected to the scissors blade 2 12.

[0025] The housing member 22 contacts the plug-in member 26 via the slot, and the plug-in member 26 contacts the block member 25 via the clamping groove.

[0026] The handle sleeve 28, the threaded rod 29 and the operating handle end 210 are made of stainless steel.
