DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0021] like Figure 1 、 Figure 3 The figure shows: a wall leveling tool, including a base 1, a connecting base 2, a connecting plate 4, a leveling plate 5, a connecting tube 6 and a hand grip 7; the connecting base 2 is fixedly connected to one end of the base 1, and a groove is provided in the connecting base 2; a T-block 3 is fixedly connected to the connecting plate 4, and the T-block 3 is adapted to the groove of the connecting base 2, and the T-block 3 is detachably inserted into the connecting base 2; the leveling plate 5 is fixedly connected to the connecting plate 4; the connecting tube 6 is arranged at the other end of the base 1; the hand grip 7 is connected to the connecting tube 6 through an adjusting assembly, and the adjusting assembly is used to adjust the engagement length of the hand grip 7 and the connecting tube 6.

[0022] Specifically, the T-block 3 is fixedly mounted on the connecting seat 2 by two fasteners 12, so as to facilitate the removal and replacement of the screed plate 5; when the screed plate 5 is worn, the fasteners 12 are removed and the screed plate 5 and the connecting plate 4 are replaced as a whole.

[0023] like Figure 2As shown, the adjustment assembly includes a slider 8 and a threaded ring 9. The threaded ring 9 is installed in the side of the connecting tube 6 away from the base 1. The threaded ring 9 is fixed axially relative to the connecting tube 6 and free circumferentially. Specifically, the threaded ring 9 is embedded in an annular groove on the inner wall of the connecting tube 6, and the side surface of the annular groove restricts the axial movement of the threaded ring 9. An adjustment rod 10 is connected to the handle rod 7 along the rod length. The adjustment rod 10 passes through the threaded ring 9 and extends into the connecting tube 6. The external thread on the adjustment rod 10 engages with the internal thread of the threaded ring 9. The end of the adjustment rod 10 extending into the connecting tube 6 is fixedly connected to the slider 8. The slider 8 and the connecting tube 6 slide together and guide each other. Specifically, the slider 8 has a sliding groove, and the inner wall of the connecting tube 6 is provided with an axial guide rail. The sliding groove and the guide rail cooperate to restrict the rotation of the slider 8, and thus the rotation of the adjustment rod 10. When the adjustment rod 10 moves relative to the connecting tube 6, the threaded ring 9 rotates. The connecting tube 6 is provided with a locking mechanism for restricting the rotation of the threaded ring 9. When the locking mechanism locks the threaded ring 9, the adjustment rod 10 cannot move.

[0024] The connecting tube 6 is fixedly connected to a strip handle 13. The locking mechanism includes a pressure rod 15, a latch 16, and a spring 17. Pin holes 18 are formed on the circumference of the threaded ring 9 and are evenly spaced around the ring 9. The pressure rod 15 is hinged in a slot on the column of the strip handle 13. The top of the latch 16 is hinged to the pressure rod 15. The connecting tube 6 has a through hole that allows the latch 16 to enter and exit. The latch 16 can pass through the through hole and insert into the pin hole 18 of the threaded ring 9. The spring 17 is connected between the pressure rod 15 and the connecting tube 6. The spring 17 pushes the pressure rod 15 upward, and the other end of the pressure rod 15 presses the pin 16 into the pin hole 18 of the threaded ring 9. At this time, the threaded ring 9 cannot rotate, and the adjusting rod 10 cannot move relative to the connecting tube 6. Holding the strip handle 13, when the pressure rod 15 is pushed downward with a finger, the other end of the pressure rod 15 is lifted, and the pin 16 is pulled out from the pin hole 18 of the threaded ring 9. At this time, the threaded ring 9 can rotate and the adjusting rod 10 can move.

[0025] The adjusting rod 10 is secured to the connecting tube 6 via a threaded ring 9 and a locking mechanism. Compared to conventional methods that require drilling a row of holes and inserting bolts, this method offers the advantages of faster adjustment and a more flexible adjustment range. During use, the threaded ring 9 can be locked and unlocked by simply moving the pressure lever 15. Once unlocked, the position of the grip 7 can be adjusted by pulling the adjusting rod 10 forward or backward, making it quick and convenient.

[0026] The outer fixing sleeve of the crossbar of the strip handle 13 is provided with an anti-skid rubber sleeve 14. The outer fixing sleeve of the hand grip 7 is provided with an anti-skid sleeve 11. Prevent the hand from slipping during operation.

[0027] The working end of the screed plate 5 is tapered, so the slurry is not easily hung on the screed plate 5.

[0028] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
