However, current mortar leveling methods typically involve using a flat slab for smoothing and finishing. During the leveling process, workers cannot expand the leveled area. Furthermore, when leveling higher walls, scaffolding and other auxiliary tools are usually required, resulting in low work efficiency.

[0003] Therefore, based on this, a design or technical improvement is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a mortar smoothing tool.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A mortar smoothing tool includes a first smoothing plate. A fixing block is vertically welded to the upper outer surface of the first smoothing plate, and a through hole is formed in the middle inner wall of the fixing block. A hand handle is provided above the fixing block, and two sets of positioning grooves that cooperate with the hand handle are symmetrically formed on the upper inner wall of the fixing block. Connecting bolts are provided on the inner walls of both ends of the hand handle. Two sets of fixing grooves are symmetrically formed on the inner walls of both ends of the first smoothing plate, and a blocking block is provided at both ends of the first smoothing plate. A spring sheet is symmetrically provided on one side of each of the two sets of blocking blocks. Multiple sets of locking handles are symmetrically provided above the first smoothing plate.

[0007] Furthermore, a connecting bracket is provided above the fixing block, and a pin is provided inside the fixing block. One end of the pin is provided with a locking collar. An extension rod is vertically welded to one side of the connecting bracket, and multiple sets of fixing protrusions are evenly distributed on the outer side of the extension rod. A hand handle is provided on the outer side of the upper end of the extension rod, and a through hole that mates with the extension rod is opened inside the hand handle. At the same time, a limiting groove that mates with the fixing protrusions is opened on the inner wall of the hand handle. A mounting box is provided at the upper end of the hand handle, and second smearing plates are provided at both ends of the first smearing plate.

[0008] Furthermore, a servo motor is installed on the inner bottom of the mounting box, and a threaded rod is provided on the rotor end of the servo motor. A positioning ring is welded on the inner side of the mounting box, and multiple sets of circular grooves are evenly opened on the inner wall of the positioning ring. A buffer spring is provided inside each set of circular grooves. A support plate is provided above the positioning ring, and a cover plate is provided at the opening end of the mounting box.

[0009] Furthermore, the blocking block is detachably mounted on both ends of the first trowel plate via a fixed groove and a spring plate, and the hand handle is detachably connected to the first trowel plate via a connecting bolt and a positioning groove.

[0010] Furthermore, the locking collar is threadedly connected to the pin, the connecting bracket is rotatably connected to the fixing block through the provided pin, the extension rod is slidably connected inside the hand handle through the provided fixing protrusion and limiting groove, and the second wiping plate is detachably installed at both ends of the first wiping plate through the provided locking handle.

[0011] Furthermore, the servo motor is detachably mounted on the inner bottom of the mounting box, the threaded rod is threadedly connected to the extension rod, and the inner diameter of the positioning ring is smaller than the outer diameter of the support plate.

[0012] Furthermore, the buffer spring is embedded inside the circular groove and abuts against the support plate, the cover plate is threaded to the opening end of the mounting box, and multiple sets of heat dissipation grooves are opened on the outer inner wall of the mounting box.

[0013] Compared with existing technologies, the advantages of this solution are: the handheld handle makes it convenient for workers to hold the equipment and smooth the mortar; the blocking blocks prevent mortar from entering by blocking the fixing grooves at both ends of the first slurry plate; the spring plates make it convenient for workers to quickly remove the blocking blocks; and the locking handles make it convenient for workers to install the second slurry plate at both ends of the first slurry plate, thus expanding the smoothed area.

[0014] The connecting bracket is rotatably connected to the top of the fixed block by a set pin and locking collar, which makes it convenient for workers to hold the hand rod to smooth the mortar. The angle of the first smoothing plate can be adjusted to keep the first smoothing plate in a parallel state. The threaded rod is driven to rotate by a set servo motor. Under the limiting action of the fixed protrusion and the limiting groove, the extension length of the extension rod can be adjusted, so that mortar of different heights can be smoothed.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figure 1-5 The mortar smoothing tool shown includes a first smoothing plate and a fixing block 2 vertically welded to the upper surface of the first smoothing plate 1. A hand handle 3 is installed above the fixing block 2 by a connecting bolt 5. The hand handle 3 is limited by a positioning groove 4. Before smoothing, the worker needs to install the blocking block 6 at both ends of the first smoothing plate 1 with a spring plate 8 to block the fixing groove 7 and prevent mortar from entering the groove during smoothing. At the same time, tighten the locking handle 9. At this time, the worker can use the hand handle 3 to smooth the mortar.

[0024] In one embodiment, the connecting bracket 11 is installed on both sides of the fixing block 2, so that the round hole at the bottom of the connecting bracket 11 is aligned with the through hole on the inner wall of the fixing block 2. At the same time, the pin 12 is passed through the middle of the through hole, so that the connecting bracket 11 and the fixing block 2 can be rotatably connected. This allows the operator to adjust the angle between the connecting bracket 11 and the first troweling plate 1 when smoothing, so that the first troweling plate 1 always remains horizontal. The locking collar 13, which is threaded to one end of the pin 12, limits its movement and prevents it from falling off.

[0025] In one embodiment, when it is necessary to expand the smoothing area, first apply a pulling force to the block 6 to pull the spring plate 8 out of the fixed groove 7, insert the second smoothing plate 10 into the fixed groove 7 so that the end face of the second smoothing plate 10 fits tightly with the end face of the first smoothing plate 1, and then tighten the locking handle 9 to lock and fix the second smoothing plate 10. At this time, by using the two sets of second smoothing plates 10 in conjunction with the first smoothing plate 1, the smoothing area can be expanded, thereby improving work efficiency.

[0026] In one embodiment, a fixing screw is used to pass through the inner wall of the servo motor 19 housing to install the servo motor 19 on the inner bottom of the mounting box 18. Then, the support plate 24 is snapped into the inside of the mounting box 18, and the existing battery is snapped into the slot on the side of the support plate 24. The wires are passed through the round hole in the inner wall of the support plate 24 and connected to the servo motor 19. When the operator tightens the cover plate 25, the battery is appropriately squeezed to fix the battery. Multiple sets of buffer springs 23 are set to buffer the support plate 24 to prevent the cover plate 25 from excessively squeezing the battery and causing damage. Multiple sets of heat dissipation grooves opened in the inner wall of the mounting box 18 are used to dissipate heat inside the mounting box 18.

[0027] The specific workflow of this plan is as follows:

[0028] The device allows workers to easily handle the equipment with the handle 3 to smooth small areas of mortar. Simultaneously, workers can remove the block 6 and install the second trowel plate 10 at both ends of the first trowel plate 1. Tightening the locking handle 9 locks it in place. By using the first trowel plate 1 in conjunction with two sets of second trowel plates 10, the smoothing area can be expanded. When workers need to smooth higher areas of mortar, they can use the handheld lever 16 to control the first trowel plate 1 to smooth the mortar at those heights. When workers need to adjust the smoothing height, the existing battery powers the servo motor 19, driving it to rotate the threaded rod 20. Since the extension rod 14 is threadedly connected to the threaded rod 20, and with the limiting action of the fixed protrusion 15 and the limiting groove 17, the threaded rod 20 can control the extension rod 14 to slide inside the handheld lever 16 during rotation, thus completing the height adjustment and facilitating smoothing of mortar at different heights.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
