[0028] Please refer to Figures 1 - 6 , the present utility model provides a technical solution for a telescopic masonry mortar spreading tool. A telescopic masonry mortar spreading tool includes two groups of support seats 4. A threaded rod 3 is rotatably connected to each group of support seats 4. Two sections of external threads with opposite thread directions are provided at both ends of the outer surface of the threaded rod 3. A positioning plate 2 is threadedly connected to each of the two sections of external threads. One end of the threaded rod 3 penetrates into one side of the support seat 4 and is connected to a motor. The motor is fixed inside one side of the support seat 4. A limiting rod 23 is fixed on each group of support seats 4. Both of the two positioning plates 2 are slidably connected to the limiting rod 23. Two ash baffle plates 1 are connected between the two groups of positioning plates 2. A scraping plate 5 is slidably connected between the two ash baffle plates 1. A sliding mechanism matching with the scraping plate 5 is provided on the ash baffle plates 1. By driving the motor to rotate, the motor drives the threaded rod 3 to rotate. Under the limitation of the limiting rod 23, the rotation of the two threaded rods 3 will drive the positioning plates 2 on the threaded rod 3 to move. The movement of the two positioning plates 2 can drive the two ash baffle plates 1 to move, so as to closely fit the two sides of the building block. Furthermore, the distance between the two ash baffle plates 1 and the building block can be adjusted according to the width of the building block.

[0029] Refer to Figure 1 , Figure 2 and Figure 6 , the sliding mechanism includes moving grooves 11 opened on the outer sides of the two ash baffle plates 1. A fixed rod 12 is fixed inside the moving grooves 11. A moving rod 9 is slidably connected to the outer surface of the fixed rod 12. A support rod 7 is fixed to the end of the moving rod 9 penetrating out of the moving groove 11. An activity hole 8 is opened in the middle of the support rod 7. A connecting rod 6 is slid in the activity hole 8. One end of the connecting rod 6 penetrates out of the activity hole 8 and is clamped and connected to the end of the scraping plate 5. A limiting component matching with the activity hole 8 is provided at the other end of the connecting rod 6. The present utility model can solve the problem of the uniformity of the spreading thickness of the mortar, and the limiting connection between the connecting rod 6 and the support rod 7 is released by pulling the push rod 15 once, so as to achieve the effect of adjusting the height of the scraping plate 5. This connection method is simpler, more efficient and more convenient to operate than the cumbersome bolt connection in the prior art when applied.

[0030] Refer toFigure 3 , Figure 4 and Figure 5 , the limiting component includes a receiving cavity 13 opened in the end of the connecting rod 6. Two sliders 19 are slidably connected in the receiving cavity 13. Two chutes cooperating with the sliders 19 are opened on the inner wall of the receiving cavity 13. A moving block 14 is fixed to the top ends of the two sliders 19. A push rod 15 is provided at the end of the moving block 14. The other end of the push rod 15 penetrates out of the connecting rod 6. A spring 20 is sleeved on the outer surface of the push rod 15 and located in the receiving cavity 13. One end of the spring 20 is pressed against the end of the moving block 14, and the other end of the spring 20 is pressed against the inner wall of the receiving cavity 13. One clamping rod 17 is slidably connected to each of the two inner walls of the receiving cavity 13. The ends of the two clamping rods 17 are respectively slid on two inclined slots 16. The two inclined slots 16 are symmetrically opened on both sides of the outer surface of the moving block 14. The other end of the clamping rod 17 penetrates out of the connecting rod 6 and extends into the moving hole 8. A plurality of card slots 22 cooperating with the clamping rod 17 are vertically opened on each of the two inner walls of the moving hole 8.

[0031] Refer to Figure 3 , Figure 4 and Figure 5 , through holes 18 communicating with the receiving cavity 13 are opened on both the left and right sides of the connecting rod 6. The two clamping rods 17 are respectively slid in the two through holes 18. A through hole 2 is opened at the end of the connecting rod 6 and cooperating with the receiving cavity 13. The push rod 15 is slid in the through hole 2.

[0032] Refer to Figures 1 - 6 , a sliding hole 10 is opened at the end of the moving rod 9 located in the moving groove 11. The sliding hole 10 is sleeved on the fixed rod 12. A handle 21 is fixed to the top of the scraping plate 5. Through the arrangement of the scraping plate 5 and the handle 21, by pulling the handle 21 to move, the handle 21 drives the scraping plate 5 to move. The movement of the scraping plate 5 can drive the mortar to be pushed. Under the action of the scraping plate 5, it is convenient to evenly apply the mortar on the top of the building block.

[0033] During use, the operator places the ash baffle 1 on both sides of the building block. Subsequently, according to the width of the building block, the distance between the two ash baffles 1 and the building block is adjusted. By rotating the drive motor, the motor drives the threaded rod 3 to rotate. Under the limitation of the limiting rod 23, the rotation of the two groups of threaded rods 3 will drive the positioning plates 2 on the threaded rods 3 to move. The movement of the two positioning plates 2 can drive the two ash baffles 1 to move, so as to be closely attached to both sides of the building block. Furthermore, according to the width of the building block, the distance between the two ash baffles 1 and the building block can be adjusted. Subsequently, a scraping plate 5 with a suitable length is selected according to the distance between the two adjusted ash baffles 1 and is clamped and connected to the two connecting rods 6;

[0034] Subsequently, the worker pours the mortar between the two ash baffle plates 1. The ash baffle plates 1 on both sides will limit the outflow of the mortar from both sides, avoiding waste of the mortar. Then, the worker adjusts the height of the bottom end of the scraping plate 5 and pulls the scraping plate 5 back and forth, thereby being able to push the mortar to flow, facilitating the even coating of the mortar on the top of the building block. Before adjusting the height of the scraping plate 5 from the mortar, it is necessary to first drive the limiting component to release the fixation between the connecting rod 6 and the support rod 7. The operation process of the limiting component is as follows: Pull the push rod 15 towards the end away from the scraping plate 5. The movement of the push rod 15 drives the moving block 14 and the inclined groove 16 to move towards the end away from the scraping plate 5. When the moving block 14 moves, it compresses the spring 20. Under the guiding action of the inclined surface of the inclined groove 16, the clamping rod 17 will be pushed to move. Under the action of the through hole 18, the clamping rod 17 slides along the through hole 18. When the moving block 14 moves towards the end away from the scraping plate 5, it will drive the two clamping rods 17 to move along the through hole 18 into the inside of the connecting rod 6 until the ends of the two clamping rods 17 leave the clamping grooves 22 on the inner walls of both sides of the movable hole 8. Subsequently, the connecting rod 6 is vertically moved. The movement of the connecting rod 6 drives the scraping plate 5 to move vertically. After the scraping plate 5 moves to a suitable position, the push rod 15 is released. Under the action of the spring 20, the push rod 15 drives the moving block 14 and the inclined groove 16 to move towards the end close to the scraping plate 5. Under the guiding action of the inclined surface of the inclined groove 16, the movement of the moving block 14 will push the two clamping rods 17 to move along the through hole 18 to the outside of the connecting rod 6 until the ends of the two clamping rods 17 are inserted into the clamping grooves 22 on the inner walls of both sides of the movable hole 8, so as to fix the positions of the connecting rod 6 and the support rod 7, and further complete the limit after the height adjustment of the scraping plate 5;

[0035] Subsequently, the worker drives the scraping plate 5 to move by pulling the handle 21 at the top of the scraping plate 5. The scraping plate 5 drives the connecting rod 6 and the support rod 7 to move. The support rod 7 drives the moving rod 9 to move in the moving groove 11. When the moving rod 9 moves, the sliding hole 10 at the end of the moving rod 9 slides on the outer surface of the fixed rod 12. As the scraping plate 5 moves, the mortar is pushed. Under the action of the scraping plate 5, it is convenient to evenly coat the mortar on the top of the building block.

[0036] Although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
