Example three:

referring to fig. 1-4, in the above embodiment, two guard rails 500 are installed on the top of the moving cart 110, and the two guard rails 500 are respectively located at the front and rear sides of the sliding rail 450, and the guard rails 500 are provided to guarantee safety of workers.

The working principle and the using process of the invention are as follows: when the invention is put into practical use, after a worker stands on the platform 230, the electric push rod 220 drives the platform 230 to move upwards through the rectangular block, in the process, the first magnet 251 attracts the second magnet 252, then the support plate 240 moves towards the outer side of the moving trolley along the platform 230 until the first magnet 251 and the second magnet 252 are attached to each other, at the moment, the support plate 240 and the vertical plate 210 are abutted against each other, the stability of the platform is improved, meanwhile, the pressure born by the electric push rod 220 is also reduced, the probability of damage of the electric push rod 220 is reduced, the service life of the electric push rod 220 is prolonged, then the sector plate 420 and the tool table 310 are separated from clamping connection, the spring 360 struts the tool table 310, then the worker pulls the cover body 440 along the tool table 310, the cover body 440 releases the rope body 430, and then the inner end of the stay bar 320 connected with the rope body 430 drops downwards, the support rods 320 collide with the plate body 341, the plate body 341 drives the rotating shaft 330 to rotate until the top of the tool table 310 and the top of the platform 230 are located on the same horizontal plane, at the moment, the plate body 341 limits the support rods 320, then when a worker stands on the tool table 310, the weight of the worker and the weight of the tool table 310 are completely pressed on the two support rods 320, the force is transmitted to the tray body 342 through the plate body 341 by the support rods 320, the tray body 342 is clamped with the clamping piece 351, and the sleeve plate 353 limits the clamping piece 351, so that the rotating shaft 330 cannot rotate, the support rods 320 can firmly support the tool table 310, then the sliding plate 460 is moved along the sliding rail 450, the sliding plate 460 is clamped with the cover body 440, when the tool table 310 is folded, the cover body 440 only needs to be restored to the original position, the support rods 320 can be folded, the structure is simple, and the use is convenient.

In the present invention, the term "plurality" means two or more unless explicitly defined otherwise. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. The terms "mounted," "connected," "fixed," and the like are to be construed broadly, and for example, "connected" may be a fixed connection, a removable connection, or an integral connection; "coupled" may be direct or indirect through an intermediary. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

It will be understood that when an element is referred to as being "mounted to," "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.

In the description herein, the description of the terms "one embodiment," "some embodiments," "specific embodiments," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
