[0020] When using the trowel machine, the staff holds the handle 7 at the end of the connecting rod 4 with both hands, lifts the supporting structure 5 to a high place, and then starts the gasoline engine 2. The gasoline engine 2 rotates with the trowel plate 3, and uses the rotating trowel plate 3 to smooth the concrete floor. During this process, the lower end of the supporting structure 5 has a large space from the ground, which will not affect the normal troweling operation, and the protective frame 6 plays a protective role. When the troweling is completed, the trowel machine is stably placed, and the supporting structure 5 can be lowered to support the connecting rod 4 to ensure the placement stability of the entire trowel machine, avoid the warping of the structure at the fixed seat 1 caused by the force on the connecting rod end 4, and ensure the placement safety. When the trowel machine needs to be used again, move the supporting structure 5 up to make way, and then use the trowel machine.
[0021] According to the above embodiment, the support structure 5 includes a vertical rod 501, a strip hole 502, a connecting frame 503 and a guide component 504. The strip hole 502 is opened on the vertical rod 501, the connecting frame 503 is set at the lower end of the vertical rod 501, and the guide component 504 is installed at the lower end of the connecting frame 503. The support structure 5 also includes a limiting component 505. The vertical rod 501 is sleeved on the positioning rod 9 through the strip hole 502. The limiting component 505 is set on the vertical rod 501, and the limiting component 505 contacts the positioning rod 9. The vertical rod 501 and the connecting frame 503 are fixedly connected by screws. The guide component 504 includes a mounting plate 5041, The movable rod 5042, the adjustment block 5043, the wheel frame 5044, the wheel 5045 and the buffer spring 5046, the mounting plate 5041 is fixed to the lower end of the connecting frame 503, the movable rod 5042 is fixedly connected to the adjustment block 5043, and the movable rod 5042 passes through the mounting plate 5041, the lower end of the movable rod 5042 is threadedly connected to the wheel frame 5044, the wheel 5045 is mounted on the wheel frame 5044, the buffer spring 5046 is sleeved on the movable rod 5042, and the buffer spring 5046 is located between the mounting plate 5041 and the adjustment block 5043, the limiting assembly 505 includes a control frame 5051, a first limiting rod 5052, a second limiting rod 5053, a guide rod 5054 and a return spring 5055. The first limiting rod 5052 and the second limiting rod 5053 are fixed to the end of the control frame 5051, and the first limiting rod 5052 and the second limiting rod 5053 are plugged and installed on the vertical rod 501. The guide rod 5054 runs through the control frame 5051, and the end of the guide rod 5054 is threadedly connected to the vertical rod 501. A baffle is provided at the end of the guide rod 5054. The return spring 5055 is sleeved on the guide rod 5054, and the return spring 5055 is located between the control frame 5051 and the baffle. Through the support structure 5, when After the trowel machine is used, the supporting structure 5 can be used to support the connecting rod 4, thereby improving the placement stability of the connecting rod 4, thereby avoiding the force on the end of the connecting rod 4 causing the structure at the fixed seat 1 to tilt, and ensuring the placement safety. A guide component 504 is set at the lower end of the connecting frame 503. In addition to playing a supporting role, it can also guide the movement to facilitate the movement of the entire trowel machine. A limit component 505 is set on the vertical rod 501, which is used in conjunction with the strip hole 502 on the vertical rod 501. The entire supporting structure 5 can be raised and lowered on the positioning rod 9, which is convenient for the retraction and extension of the supporting structure 5, so that the use of the trowel machine is not affected.
[0022] When using the trowel machine, it can first be moved through the guide assembly 504 in the support structure 5. During the movement, the wheel 5045 rotates on the wheel frame 5044, and is used in conjunction with the movable rod 5042 and the buffer spring 5046. It can play an auxiliary supporting and guiding role in the process of a single person moving the trowel machine, thereby facilitating the movement of the entire trowel machine. During this process, the positioning rod 9 on the mounting seat 8 is located at the upper end of the strip hole 502 on the vertical rod 501, and the first limiting rod 5052 has a limiting and fixing effect on the positioning rod 9 to ensure the stability of the support structure 5. When it moves to the appropriate position, the first limiting rod 5052 and the second limiting rod 5053 are pulled outward by the control frame 5051 to make way, and the control frame 5051 moves along the guide rod 5054 and compresses the return spring 5055, and then through The strip hole 502 moves up the vertical rod 501, and the vertical rod 501 brings the connecting frame 503 and the guide assembly 504 at the lower end up off the ground until the positioning rod 9 is at the lowest end of the strip hole 502. After releasing the control frame 5051, under the action of the return spring 5055, the control frame 5051 brings the first limit rod 5052 and the second limit rod 5053 to move, and the end of the limit rod is inserted into the strip hole 502. At this time, the second limit rod 5053 limits the positioning rod 9, ensuring that the support structure 5 is stably set at the highest point relative to the positioning rod 9, and then the smoothing operation can be carried out. At this time, the support structure 5 has a large space from the ground, which does not affect the normal smoothing. When the smoothing is completed, the support structure 5 can be lowered again for support or guiding movement. The structure is simple and the use effect is good.
