[0015] The principles and features of the utility model are described below, and the examples are only used to explain the utility model, and are not used to limit the scope of the utility model.

[0016] It should be noted that when a part or component is considered to be "connected", "located", "assembled" on another part or component, it can be directly arranged on another part and component or there can be a middle part and component. The terms "left", "right", "up", "down" and similar expressions used herein are only for the purpose of illustration.

[0017] In a specific embodiment, as shown in Figs. 1-2 :

[0018] A labor-saving operating rod, including hoisting equipment 1, the operating end of the hoisting equipment 1 is fixedly installed with connecting piece 2, the connecting piece 2 is rotatably connected with operating rod 3, the connecting piece 2 is fixedly installed with ratchet wheel 23, the operating rod 3 is rotatably connected with pawl 42 matched with the ratchet wheel 23, the pawl 42 is clamped into the ratchet wheel 23 to limit the operating rod 3 from rotating to the ground.

[0019] The lifting device 1 can be a telescopic rod, a cylinder, an oil cylinder, or a winch, etc. The output end of the lifting device 1 is fixedly installed with a clamping device to clamp a workpiece to be moved. The connecting piece 2 is fixedly installed at the output end of the lifting device 1 to prevent the lifting device 1 from being stuck by the connecting piece 2 during telescoping.

[0020] In the embodiment, two installation grooves 21 are formed on the same side of the connecting piece 2. A first shaft rod 22 is fixedly installed on the connecting piece 2 and passes through the two installation grooves 21. A connecting plate 4 is rotatably connected in the installation groove 21 by the first shaft rod 22. The two connecting plates 4 are fixedly connected with the operating rod 3. The side of the installation groove 21 close to the operating rod 3 and the upper and lower sides are all open, so that the connecting plate 4 will not be stuck during rotation.

[0021] Further, the ratchet wheel 23 is fixedly installed between the two installation grooves 21. A second shaft rod 41 is fixedly installed between the two connecting plates 4. The pawl 42 is sleeved on the second shaft rod 41 to realize rotation.

[0022] In the embodiment, the ratchet wheel 23 is provided with ratchet teeth only on the side close to the operating rod 3. The end of the pawl 42 away from the second shaft rod 41 extends to the outside between the two connecting plates 4, facilitating manual operation of the pawl 42 to adjust the height of the end of the operating rod 3.

[0023] The labor-saving operating rod can be further optimized or / and improved according to actual needs:

[0024] The elastic member 43 is fixedly installed between the two connecting plates 4. The output end of the elastic member 43 abuts against the pawl 42 to drive the pawl 42 to be clamped with the ratchet wheel 23, so that when the operating rod 3 needs to be rotated upward, the pawl 42 can be clamped into the ratchet teeth above the current position without manual operation. The operating rod 3 can be directly pulled upward to make the pawl 42 clamped into the ratchet teeth above the current position, and the operation is more convenient. When the operating rod 3 needs to be rotated downward, the pawl 42 can be pulled away from the ratchet wheel 23 to rotate the operating rod 3 downward. After rotating to the specified position, the pawl 42 is released, and the elastic force of the elastic member 43 recovering from deformation can re-clamp the pawl 42 into the ratchet wheel 23.

[0025] In the embodiment, the elastic member 43 is a torsion spring. In other embodiments, the elastic member 43 can also be a spiral spring, a plate spring, or other workpieces that can apply a pushing force to the pawl 42.

[0026] In summary: by clamping the pawl 42 into the ratchet 23, the operating rod 3 is kept at a fixed height, even if unmanned, the operating rod 3 will not fall, and when the operator uses it, he does not need to bear part of the weight of the operating rod 3, and only needs to operate by pushing, pulling, etc. The operation can be completed, and the worker does not need to hold the operating rod 3, so that the worker is more labor-saving when working, and even after long-time work, the muscles will not be tired, and the height of the operating end of the operating rod 3 can be adjusted according to different heights or environments to adapt, so that different people can operate in a more comfortable posture.

[0027] The above is only a preferred embodiment of the present application, and does not limit the present application in any form; any person skilled in the art can implement the present application according to the drawings and the above; however, any equivalent changes, modifications and evolution made by those skilled in the art within the scope of the technical scheme of the present application, using the above disclosed technical content, are equivalent embodiments of the present application; at the same time, any equivalent changes, modifications and evolution of the above embodiments according to the essential technology of the present application are still within the protection scope of the technical scheme of the present application.
