Referring to Fig. 8, introduce a kind of cantilever arrangement 10000 in this together, including described carrying column 1000 is with that can revolve It is held in the rotation folding arm 2000 on carrying column 1000 with turning, there is preferable levels operation power and operating efficiency for providing Hoisting apparatus.

Wherein, rotation folding arm 2000 includes the first arm 2100 and the second arm 2200, and the first arm 2100 is connected with first respectively Portion 0211, second connecting portion 0311a are fixedly connected, and the one end of the first arm 2100 away from carrying column 1000 is cut with scissors with the second arm 2200 Connect.

Here, the first arm 2100 is rotated integrally with shaft 0200, swivel mount 0310, there is provided the entirety of rotation folding arm 2000 Rotation.Second arm 2200 can rotate around the articulated section of the first arm 2100 and the second arm 2200, make the first arm 2100 and the second arm 2200 stretch or fold.

In other words, rotation folding arm 2000 has two kinds of rotary motions, that is, rotates the integral-rotation and the second arm of folding arm 2000 2200 rotation is overhanging.In the motion process of rotation folding arm 2000, hinder torque that there is fairly obvious change.Particularly second The overhanging process of rotation of arm 2200, acting force arm increases rapidly, and rotation folding arm 2000 occurs fairly obvious under change moment of flexure It is sagging.Due to carrying the carrying compensation of column 1000, movement interference and drift effect are significantly reduced, levels operation power is dropped It is low to arrive ideal range.User only needs to input the levels operation power of as little as several newton, you can driving rotation folding arm 2000 rotates, and makes behaviour Greatly improved as efficiency.

In all examples being illustrated and described herein, any occurrence should be construed as merely exemplary, without It is that therefore, other examples of exemplary embodiment can have different values as limitation.

It should be noted that:Similar label and letter represents similar terms in following accompanying drawing, therefore, once a certain Xiang Yi It is defined in individual accompanying drawing, then it further need not be defined and explained in subsequent accompanying drawing.

Embodiment described above only expresses the several embodiments of the present invention, and it describes more specific and detailed, but simultaneously Therefore limitation of the scope of the invention can not be interpreted as.It should be pointed out that for the person of ordinary skill of the art, Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention Enclose.Therefore, protection scope of the present invention should be determined by the appended claims.
