[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] A new type of trowel for masonry with built-in grouting function, such as Figure 1 As shown in Figure 2, the trowel includes a trowel body 1, a trowel handle 2 at one end of the trowel body 1, a groove 3 on the upper surface of the trowel handle 2, one end of the groove 3 penetrating the tail of the trowel handle 2, a grouting knife 4 installed in the groove 3, the grouting knife 4 being rotatably installed in the groove 3 via a rotating shaft, a chamber 5 located in the trowel handle 2 and next to the groove 3, one end of the rotating shaft extending into the chamber 5, and a worm gear 6 installed at its end, a worm 7 being rotatably installed in the chamber 5, one end of the worm 7 extending out of the outer wall of the trowel handle 2, the worm 7 meshing with the worm gear 6, and a knob 8 installed at the end of the worm 7 extending out of the outer wall of the trowel handle 2;

[0036] A sealing cover 9 for sealing the groove 3 is installed at the opening of the groove 3. One end of the sealing cover 9 is rotatably installed at the opening of the groove 3. A fixing component 10 for fixing the grouting knife 4 and the sealing cover 9 is installed on one side wall of the trowel handle 2.

[0037] like Figure 3 As shown, in some embodiments, the grouting knife 4 is integrally formed from three parts: a rotating base 401, a cylindrical rod 402, and a hemispherical body 403. The cylindrical rod 402 has a length of 50 mm and a diameter of 10 mm, and the hemispherical body 403 has a diameter of 10 mm.

[0038] like Figure 4 As shown (refer to) Figure 2The trowel handle 2 has a first fixing hole 201 and a second fixing hole 202 on its side wall. The sealing cover 9 and the grouting knife 4 have a first limiting hole 11 and a second limiting hole 12 on their side walls, respectively. The fixing assembly 10 includes a limiting pin 13 installed in the first fixing hole 201 and the second fixing hole 202. The limiting pin 13 is divided into a movable head 1301 and a fixed head 1302. The movable head 1301 is slidably installed on the fixed head 1302, and a spring 1303 is installed between the movable head 1301 and the fixed head 1302. A knob 1304 is provided at one end of the fixed head 1302. The movable head 1301 is slidably installed in the first fixing hole 201 and the second fixing hole 202, and the movable head 1301 protrudes into the groove 3. The fixed head 1302 is threadedly connected in the first fixing hole 201 and the second fixing hole 202.

[0039] like Figure 4 , Figure 6 As shown, in order to prevent the grouting knife 4 from wobbling from side to side during use and thus increase the stability of the entire grouting knife 4, in some embodiments, a stabilizing block 14 is installed in the groove 3 and on one side near the end of the trowel handle 2. The stabilizing block 14 and the sealing cover 9 are both provided with semi-circular grooves 15 that match the shape of the cylindrical rod 402.

[0040] In some embodiments, in order to improve the sealing effect of the sealing cap 9 on the groove 3 and prevent impurities or dirt from entering the groove 3, a sliding groove 16 is also provided on the sealing cap 9. A sealing cap 17 for sealing the semi-circular groove 15 is slidably installed in the sliding groove 16, and a spring 18 is installed between one end of the sealing cap 17 and the top surface of the sliding groove 16.

[0041] Both knob 8 and knob 1304 have knurled patterns on their outer walls. The knurling increases the friction between the worker's fingers and knobs 8 and 1304, preventing slippage when rotating them.

[0042] like Figure 7 As shown, in some preferred embodiments, in order to increase the grouting utility of the trowel body 1, a chamfer 19 is provided on the right-angled side of the trowel body 1 away from the trowel handle 2.

[0043] Several arc-shaped grooves 20 are provided at one end of the trowel handle 2. The arc-shaped grooves 20 are ergonomic, which improves the worker's grip and feel on the trowel body 1, thereby increasing the stability of the trowel body 1 during use.

[0044] The working process and beneficial effects of this utility model are as follows:

[0045] Before using the trowel body 1, first release the fixing component 10 from fixing the grouting knife 4 and the sealing cover 9. By turning the knob 8, the knob 8 drives the worm gear 7 to rotate, and the worm gear 7 drives the meshing worm wheel 6 to rotate. The worm wheel 6 drives the rotating shaft and the grouting knife 4 to rotate 180 degrees in the groove 3. During the process of rotating the grouting knife 4 to 180 degrees, the grouting knife 4 will squeeze the movable head 1301 protruding into the groove 3 and compress the spring 1303, so that the movable head 1301 retracts into the second fixing hole 202. Inside, when the grouting knife 4 rotates to 180 degrees, the movable head 1301 in the second fixing hole 202 is coaxial with the second limiting hole 12 on the grouting knife 4, and under the action of the reaction force of the spring 1303, the movable head 1301 is pushed into the second limiting hole 12. Finally, by rotating the knob 2 1304, the knob 2 1304 drives the fixing head 1302 to rotate in the second fixing hole 202 and press the spring 1303, so that the movable head 1301 is more firmly fixed in the second limiting hole 12.

[0046] Finally, the sealing cap 9 is closed. When the first limiting hole 11 on the sealing cap 9 is rotated to be coaxial with the movable head 1301 in the first fixing hole 201, the movable head 1301 is pushed into the first limiting hole 11 by the reaction force of the spring 1303. Finally, by rotating the knob 1304, the knob 1304 drives the fixing head 1302 to rotate in the first fixing hole 201 and press the spring 1303, so that the movable head 1301 is more firmly fixed in the first limiting hole 11. After the above operation, the fixing of the grouting knife 4 and the sealing cap 9 is completed, and the trowel body 1 is formed into a trowel body 1 with the grouting knife 4. It is convenient for workers to directly use the trowel body 1 with the grouting knife 4 to treat the mortar joints when building walls. When not in use, the fixing component 10 is released to fix the grouting knife 4 and the sealing cap 9, the sealing cap 9 is opened, the grouting knife 4 is rotated into the groove 3 and then the sealing cap 9 is closed, so that the trowel body 1 is easy to carry.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
