The working principle of the invention is as follows: when in use, the trolley main body 1 is moved to a limited position, then the first hydraulic cylinder 2 is started, the first hydraulic cylinder 2 at the moment relatively moves downwards along with the extension of the output end of the first hydraulic cylinder 2 because the first hydraulic cylinder 2 is in a suspension state, meanwhile, the first hydraulic cylinder 2 drives the driving disc 5 to move downwards, the driving disc 5 is connected with the driving disc 4 through a magnet, and the rod body 32 is mainly supported by the driving disc 5 and the driving disc 4 when in suspension, so that the rod body 32 at the moment starts to fall under the action of the self weight of the rod body 32 and the driving disc 5 and the driving disc 4, the bottom level of the rod body 32 is lower than the bottom level of the first hydraulic cylinder 2, the rod body 32 is firstly contacted with the bottom surface of the building 101, the bottom of the first hydraulic cylinder 2 is contacted with the bottom surface of the building 101, and the first hydraulic cylinder 2 is started continuously, the first hydraulic cylinder 2 pushes the trolley main body 1 upwards at the moment, so that the trolley main body 1 starts to ascend, the supporting rod 3 can not synchronously ascend along with the trolley main body 1 at the moment, so that the position of the supporting rod 3 is unchanged, after the trolley main body 1 is pushed up to a limited height, the first hydraulic cylinder 2 is closed, at the moment, the handle 14 corresponding to the supporting rod 3 slidably arranged at the bottom of the trolley main body 1 can be rotated, the driving gear 13 drives the central gear 12 to start rotating, so that the rack 11 starts to drive the clamping block 8 to move inwards under the action of the central gear 12 until the groove in the clamping groove 10 in the middle part of the clamping block 8 is clamped with the groove on the outer wall of the supporting rod 3, at the moment, the first hydraulic cylinder 2 can be started, the first hydraulic cylinder 2 starts to retract, the trolley main body 1 is supported by the supporting rod 3 and the clamping block 8, and the speed and the efficiency of the lifting height of the trolley main body 1 are higher, the trolley main body 1 is not actually supported by the first hydraulic cylinder 2, so that the accident that the deformation or even damage of the building body 101 occurs after the building is caused by the retraction of the first hydraulic cylinder 2 during the supporting is effectively avoided;

if the template above the trolley body 1 still does not move to the limited height, at this time, the second hydraulic cylinder 7 at the top of the trolley body 1 is started to push the transmission plate 6 to move upwards, so that the transmission plate 6 drives the support rod 3 at the top of the trolley body 1 to move upwards synchronously by pushing the transmission disc 4, so that the support rod 3 starts to push the template above the trolley body 1 to ascend, until the template is pushed to the limited height, and after the template is pushed to the limited height, the corresponding support rod 3 is fixed by rotating the corresponding handle 14, at this time, the second hydraulic cylinder 7 can be retracted, and the template is supported by the support rod 3, thereby reducing the accident that shrinkage or even damage occurs after the second hydraulic cylinder 7 is used for a long time, then, the second hydraulic cylinder 7 at the side wall of the trolley body 1 is started, so that the corresponding transmission plate 6 drives the corresponding support rod 3 to move outwards of the trolley body 1, so that the support rod 3 pushes the corresponding template to the limited position, and after the support rod 3 is fixed, the second hydraulic cylinder 7 is retracted again;

Furthermore, in actual use, the handle 14 can be replaced by the auxiliary chain wheel 16, and then the central chain wheel 15, the transmission rod 17 and the motor 18 are additionally arranged on the trolley main body 1, so that after the position adjustment of all the support rods 3 of the trolley main body 1 is completed, the motor 18 is started, namely the central chain wheel 15 drives a plurality of groups of auxiliary chain wheels 16 to synchronously rotate through a chain, so that the power of synchronously sliding all the clamping blocks 8 is reduced, and the manual operation required by a worker in the process of adjusting the template position is reduced, so that the whole operation is more convenient and labor-saving;

Still further, the supporting rod 3 installed at the bottom of the trolley body 1 can be replaced by the supporting rod 3 composed of the base 31 and the rod body 32, so that the angle between the base 31 and the rod body 32 can be changed, when a certain horizontal error exists after the bottom surface of the building body 101 is built, the corresponding position of the trolley body 1 can be jacked up by starting the corresponding first hydraulic cylinder 2, the probability of fracture at the connecting position of the first hydraulic cylinder 2 and the trolley body 1 can be effectively reduced due to the fact that the first hydraulic cylinder 2 is connected with the trolley body 1 through a ball shaft, meanwhile, the angle between the base 31 and the rod body 32 can be changed after the trolley body 1 is adjusted, the base 31 can still be kept in a state of being attached to the bottom surface of the building body 101, the supporting effect of the supporting rod 3 on the trolley body 1 is guaranteed, and the trolley body 1 is more stable in use.
