[0022] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following further details the present invention in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Please refer to Figures 1 to 4 , the present invention provides a plastering tool for building construction, including a plate body 1. A fixed block 2 is fixedly connected to the upper surface of the plate body 1. A plurality of equally spaced limit holes 3 are opened inside the fixed block 2. An auxiliary block 4 is slidably connected to the outer surface of the fixed block 2. A connecting block 5 is fixedly connected to the upper surface of the auxiliary block 4. A handle 6 is rotatably connected inside the connecting block 5. Two groups of limit rods 7 are slidably connected inside the auxiliary block 4. One ends of the two groups of limit rods 7 close to each other extend into the limit holes 3. An auxiliary gear 8 is fixedly connected to the left end of the handle 6. A transmission rod 9 is slidably connected inside the connecting block 5. A limit tooth block 10 is fixedly connected to the right end of the transmission rod 9. The limit tooth block 10 meshes with the auxiliary gear 8.

[0024] Apply mortar using the plate body 1, and pull the limit rod 7 to move it out of the limit hole 3, and then disassemble the auxiliary block 4 from the fixed block 2, so as to achieve the ability to quickly disassemble the grip 6, facilitating the replacement of the plate body 1 or the grip 6 separately after long-term use. At the same time, it can also avoid the situation of rusting due to screw connection, and rely on pulling the transmission rod 9 to drive the limit tooth block 10 to move, so that its meshing relationship with the auxiliary gear 8 is released, and then rotate the grip 6 to change its angle, realizing the ability to conveniently change the angle of the grip 6, so as to facilitate use in different situations.

[0025] Furthermore, an auxiliary spring 11 is sleeved on the outer surface of each group of limit rods 7. One end of the two auxiliary springs 11 close to each other is fixedly connected to the inner wall of the limit rod 7, and one end of the two auxiliary springs 11 far from each other is fixedly connected to the inner side wall of the auxiliary block 4. The auxiliary spring 11 can continuously apply pressure to the limit rod 7 by using its own telescopic ability, enabling the limit rod 7 to have the ability of automatic reset, increasing the convenience when limiting the auxiliary block 4, and at the same time improving the firmness of the limit rod 7 during limiting.

[0026] Furthermore, one end of the two limit rods 7 far from each other is fixedly connected together with a baffle 12, and one side surface of the two baffles 12 far from each other is fixedly connected with an auxiliary handle 13. The cooperation of the baffle 12 and the auxiliary handle 13 can provide a good force point for the limit rod 7, increasing the convenience when it is necessary to pull the limit rod 7 and improving the convenience of the device during use.

[0027] Furthermore, two reinforcing rings 14 are fixedly connected to the outer surface of each auxiliary handle 13. One end of the two groups of reinforcing rings 14 close to each other is fixedly connected to the side surface of the baffle 12 far from each other. The reinforcing ring 14 can increase the fixed connection area between the auxiliary handle 13 and the baffle 12, making the connection relationship between the two more firm, preventing the possibility of breakage at the connection after long-term use, and increasing the firmness of the device.

[0028] Furthermore, a sponge sleeve 15 is sleeved on the outer surface of the grip 6, and a plurality of groups of rubber blocks 16 arranged at equal distances are fixedly connected to the outer surface of the sponge sleeve 15. The sponge sleeve 15 can improve the comfort of the operator when grasping the grip 6, and the rubber blocks 16 can increase the firmness when grasping the grip 6, avoiding the situation of dropping the hand.

[0029] Furthermore, an auxiliary bearing 17 is sleeved on the outer surface of the grip 6, and the auxiliary bearing 17 is embedded in the inside of the connecting block 5. The auxiliary bearing 17 can reduce the friction generated when the grip 6 rotates, making the grip 6 more sensitive when rotating, and at the same time reducing the wear speed of the grip 6 and increasing the durability of the grip 6.

[0030] Further, a return spring 18 is sleeved on the outer surface of the transmission rod 9. The right end of the return spring 18 is fixedly connected to the left side surface of the limit tooth block 10, and the left end of the return spring 18 is fixedly connected to the inner side wall of the connection block 5. The return spring 18 can continuously apply pressure to the transmission rod 9 by virtue of its own telescopic ability, enabling the transmission rod 9 to have the ability of automatic reset, increasing the convenience when limiting the auxiliary gear 8, and at the same time improving the firmness of the limit tooth block 10 during limiting.

[0031] Further, a retaining ring 19 is fixedly connected to the left end of the transmission rod 9, and a pulling handle 20 is rotatably connected to the left end of the retaining ring 19. The cooperation of the retaining ring 19 and the pulling handle 20 can provide a good force application point for the transmission rod 9, increasing the convenience when the transmission rod 9 needs to be pulled and improving the convenience of the device during use.

[0032] Working principle: When in use, hold the grip 6 by hand, and then apply the mortar on the wall surface through the plate body 1. The sponge sleeve 15 and the rubber block 16 can improve the comfort and firmness when holding the grip 6. When the plate body 1 is used for a long time or the grip 6 is damaged and needs to be disassembled, pull the auxiliary handle 13, which will drive the baffle 12 and the limit rod 7 to move, and make the limit rod 7 move out of the limit hole 3. At the same time, the auxiliary spring 11 will retract, and then the auxiliary block 4 is in an unobstructed state. At this time, the auxiliary block 4 can be conveniently removed from the surface of the fixed block 2, so that the grip 6 can be disassembled from the plate body 1. After replacing the damaged parts, the auxiliary block 4 is reset, and then the auxiliary handle 13 is released. At this time, the resilience of the auxiliary spring 11 can push the limit rod 7 to reset and make it insert into the limit hole 3 again for limiting, achieving the ability to conveniently disassemble the plastering tool without using screws and avoiding the screws from rusting and being unable to be disassembled for a long time. When the angle of the grip 6 needs to be adjusted, pull the pulling handle 20, which will drive the retaining ring 19 and the transmission rod 9 to move, and at the same time make the limit tooth block 10 move. At this time, the return spring 18 will be compressed, and the engagement relationship between the limit tooth block 10 and the auxiliary gear 8 will be released, and then the grip 6 is in an unobstructed state. At this time, the grip 6 can be rotated to change its angle. The auxiliary bearing 17 can improve the sensitivity of the grip 6 during rotation. When the angle is adjusted to the appropriate position, release the pulling handle 20. At this time, the resilience of the return spring 18 can push the limit tooth block 10 to engage with the auxiliary gear 8 again, thereby locking the position of the grip 6, achieving the ability to quickly change the angle of the grip 6, so as to adapt to different working environments and effectively increasing the applicability of the plastering tool for building construction.
