The specific working process of the invention is as follows:

(1) support for farmer roof

First, the support frame 18 is snapped to the lower surface of the support base 1, the whole device is placed on the ground, then, under the automatic action of the whole device, the driving block 19 slides downwards in the supporting frame 18, so that the connecting block 20 drives the driving gear 22 to rotate, the driving block 19 presses the return spring 27, the whole device is automatically leveled, then, the fixing cap 29 is rotated to screw the fixing cap 29 into the engaging groove 28, and at this time, the support shaft 21 cannot be rotated, and the return spring 27 is not deformed further by the external gravity, so that the whole device is safer to use, and when the driving gear 22 rotates, under the driving action of the driving belt 24, the rotating shaft 13 can drive the supporting rod 25 to unfold, further, people can rotate the extension rod 26 according to actual needs, so that the contact area of the whole device and the ground is relatively increased, and the stability of the whole device is improved.

(2) Use of different vehicles

When the length of the bearing block 12 can not contact the girder of the vehicle chassis, the bearing block 12 is pulled, so that the bearing block 12 slides on the fixing block 11 and the supporting block 10, at the moment, the clamping block 17 rotates under the blocking of the supporting block 10, because of the blocking block 16, the clamping block 17 can only rotate in a single direction, and further the bearing block 12 can only extend in a single direction, so that the whole device can support different vehicles, and meanwhile, the operation of people is convenient, after the whole device is used, the screwing rod 14 is rotated, the clamping block 17 is separated from the contact of the supporting block 10, then the bearing block 12 is pushed back to the initial position, and then the screwing rod 14 is rotated in a reverse direction.

(3) Limiting of the plug-in block 7

When using the farmer's top, will restrict the piece 5 and twist and move to going upward in piece 3 and the grafting piece 7, repeatedly push down and lift handrail 6 on, under the rotation of turning block 8, can make the piece 3 that goes upward, simultaneously under the drive of grafting piece 7, down piece 9 also goes upward to make people's volume when the limited piece 4 is touched in the mistake, grafting piece 7 can not drop from going upward piece 3, and then makes the use of whole device safer.

In summary, the following steps: the invention has the advantages that the deformation of the reset spring 27 can automatically balance the whole device, so that the whole device is more stably used, meanwhile, the contact area of the whole device and the ground can be increased through the transmission of the driving gear 22 and the transmission belt 24, the occurrence of safety accidents can be reduced through the limit of the limit block 5 when the whole device is used, meanwhile, the length of the bearing block 12 can be more stably changed through rotating the limit of the screwing rod 14, and the use of the whole device is more convenient.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
