DETAILED DESCRIPTION

[0017] To make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme in the embodiment of the present application will be described clearly and completely below in combination with the drawings in the embodiment of the present application. Obviously, the described embodiment is a part of the embodiments of the present application, rather than all the embodiments.

[0018] The existing joint tool includes a U-shaped plate 1, the bottom of the U-shaped plate 1 is provided with a connecting rod 2, the bottom of the connecting rod 2 is provided with a handle 3, the handle 3 is preferably an anti-skid plastic handle, the above is the structure of the existing joint tool, and the embodiment improves the existing joint tool, the top ends of the side plates 4 on both sides of the U-shaped plate 1 are vertically and outwardly provided with scrapers 5 in a symmetrical manner, the scrapers 5 are used to scrape off the mortar outside the joint after the joint, the length of the scraper 5 is less than the width of the side plate 4, one end of the scraper 5 is flush with the end of the side plate 4, that is, the scraper 5 is arranged on only one side of the side plate 4, and the other side of the side plate 4 is used for jointing. The U-shaped plate 1 of the embodiment is preferably a stainless steel plate, the thickness of the side plates 4 on both sides of the U-shaped plate 1 is relatively thin, and the side plates 4 on both sides can have a certain deformation, for example, a certain force is applied to the side plates 4, the side plates 4 can be slightly inclined inward, so that the spacing between the side plates 4 on both sides becomes smaller, and the thickness of the side plates 4 is preferably 0.3-1 mm.

[0019] The U-shaped plate 1 is provided with perforations on both sides of the side plates 4, and a long screw rod 6 is passed through the perforations. The long screw rod 6 is perpendicular to the side plates 4, and the long screw rod 6 is provided with nuts 7 at both ends. The distance between the front ends of the side plates 4 can be adjusted by the long screw rod 6 and the nuts 7. The side plates 4 can be slightly deformed by tightening the nuts 7 to press the side plates 4, and the two side plates 4 are inclined inward, so that the distance between the front ends of the two side plates 4 is reduced, thereby adjusting the joint width. In order to make the side plates 4 more sharp, the thickness of the top of the side plates 4 away from the scraper 5 gradually decreases, that is, the top edge of the side plates 4 is ground, so that the edge of the side plates 4 gradually thins and becomes sharp.

[0020] The embodiment also includes a tray 8 for receiving mortar. The tray 8 is provided with a groove 9 on the outer side of one side of the tray 8. The upper surface and the lower surface of the groove 9 are provided with sliding grooves 10. The groove 9 is provided with a sliding block 11. The sliding block 11 is provided with protrusions 12 corresponding to the sliding grooves 10 on the upper surface and the lower surface. The sliding block 11 can slide in the groove 9, and the protrusions 12 can slide in the sliding grooves 10. A spherical connector 13 is installed on the outer surface of the sliding block 11. The spherical connector 13 is a conventional universal ball hinge, and its structure will not be described in detail here. The spherical connector 13 is provided with a locking bolt 14. The locking bolt 14 is used to lock the rotation angle, so that the universal ball cannot rotate. The structure of the existing parts will not be described in detail here. The universal ball of the spherical connector 13 is fixedly connected to a support rod 15. The support rod 15 can rotate freely. A clamp 16 is fixed at the end of the support rod 15. The clamp 16 is sleeved with the connecting rod 2. The bolts of the clamp 16 can be tightened to fix the clamp 16 and the connecting rod 2 together.

[0021] In use, first, the mortar is applied on the wall surface of the stone retaining wall, and the tool is placed up and down, the handle 3 is below, the side with the scraper 5 is away from the wall, the distance between the front ends of the two side plates 4 is adjusted by rotating the nut 7, and the width of the joint is the distance between the front ends of the two side plates 4. After adjustment, the worker holds the handle 3 and tilts the tool outward, that is, the tool has a certain angle with the wall surface, and only the upper end of the side plate 4 contacts the mortar. The lower part of the side plate 4 gradually moves away from the wall surface, the worker holds the handle 3 and uses the upper end of the side plate 4 to cut the joint downward, and after cutting, the tool is turned by 180 degrees, and the side with the scraper 5 contacts the wall. The clamp 16 is adjusted to the appropriate position, the tray 8 is located below the U-shaped plate 1, the tray 8 is close to the wall surface, the clamp 16 is fixed, then the tray 8 can be further adjusted in position by rotating the spherical connecting piece 13, and the tray 8 can be further adjusted in position by sliding the sliding block 11, so that the tray 8 can just catch the scraped mortar. After adjustment, the locking bolt 14 is tightened, the scraper 5 is used to scrape the excess mortar on both sides of the joint, and the vertical cutting is completed. When the horizontal joint is cut, the tool is placed horizontally, the worker holds the handle 3 and uses the end of the side plate 4 to cut the joint horizontally, and after cutting, the tool is turned by 180 degrees, the position of the clamp 16 is turned, the tray 8 is adjusted so that it can catch the falling mortar, the end of the side with the scraper 5 contacts the wall, and the scraper 5 is used to scrape the excess mortar on both sides of the horizontal joint, and the horizontal cutting is completed.
