[0052] In the embodiment, only one side of the end cover on both sides of the scraping plate body 1 needs to be provided with a blade removal opening, and the end cover on the other side still adopts the end cover of the traditional structure, that is, the end cover directly covers the blade slot after being mounted on the side surface of the scraping plate body 1.

[0053] Specifically, as an optional implementation manner in the embodiment, as shown in Figures 1 to 8 The plug-in rotating connection structure between the cover 4 and the end cover body 2 comprises

[0054] A connecting hole is arranged on the end cover body 2 inside the tool withdrawal groove 21, as shown in Figure 4 The connecting hole comprises an inner hole and an outer hole; the outer hole connects the tool withdrawal groove 21 and the inner hole, and a gap 33 is arranged on one side of the end cover body 2 of the outer hole for accommodating the overturning of the cover 4.

[0055] As shown in Figure 6 The cover 4 comprises a plug-in part 41 and a shielding part 42, the plug-in part 41 is located in the connecting hole, and the blocking pin 44 is formed on both sides of the inner end of the plug-in part 41; when the blocking pin 44 is located in the inner hole, the cover 4 is adapted to translate along the end cover body 2; when the blocking pin 44 moves to the outer hole, the cover 4 is adapted to overturn outwardly.

[0056] In the embodiment, the blocking pin 44 and the cover 4 are an integral structure.

[0057] Specifically, in the embodiment, the cover 4 is a T-shaped structure as a whole, which is made by injection molding process, as shown in Figure 6 The horizontal side is the shielding part 42, and the vertical side is the plug-in part 41.

[0058] Specifically, as an optional implementation manner in the embodiment, as shown in Figure 6 A positioning protrusion 45 is arranged on the shielding part 42, and a positioning groove 25 is arranged on the end cover body 2 inside the tool withdrawal groove 21, as shown in Figure 8 When the cover 4 is translated and inserted into the bottom of the inner hole, the positioning protrusion 45 is simultaneously inserted into the positioning groove 25.

[0059] When the plug-in part is matched, the positioning protrusion 45 and the positioning groove 25 form an interference fit, which can ensure that the cover 4 can be clamped after being translated and inserted into the end cover body 2, and prevent the cover 4 from being loosened.

[0060] In the embodiment, a positioning step is formed on the end cover body 2, and the positioning groove 25 is formed between the positioning step and the end face of the end cover body 2.

[0061] The positioning protrusion 45 is a rectangular protrusion, and the positioning groove 25 is a corresponding rectangular groove.

[0062] Specifically, as an optional implementation manner in the embodiment, the moving direction of the cover 4 on the end cover body 2 is consistent with the thickness direction of the tool blade 5 in the tool groove.

[0063] As shown in Figure 1 The so-called thickness direction of the tool blade 5 refers toFigure 1 After the cover 4 is flipped down to close the retreat slot 21 in the vertical direction, the cover 4 is then translated upward to be inserted into the end cover body 2, so that the end cover is clamped.

[0064] According to the design requirements of the actual putty scraper, the rotation and translation directions of the cover 4 on the scraper can also be adjusted adaptively.

[0065] Specifically, as an optional embodiment in the present embodiment, as shown in Figure 1 , Figure 5 and Figure 8 , an outward inclined surface 22 is formed on the end cover body 2 inside the gap 33, which is adapted to cooperate with the cover 4 in the open state, so as to enlarge the opening angle of the cover 4.

[0066] When the pin shaft of the cover 4 is in the outer hole, it can only be flipped by 90 degrees. At this time, although the blade 5 can be normally moved out of the knife slot, the cover 4 will still affect the blade 5. Now, due to the design of the outward inclined surface 22, the cover 4 can continue to flip outward, that is, the flip angle of the cover 4 changes from 90 degrees to an obtuse angle. The larger the opening angle of the cover 4, the smaller the influence on the movement of the blade 5.

[0067] Specifically, as shown in Figure 6 , a plurality of anti-skid ribs 44 are arranged on the cover 4. The design of the anti-skid ribs 44 facilitates the translation of the cover 4 by the operator.

After the end cover body 2 is installed, the cover 4 is also installed.

[0069] As shown in Figure 4 , the connecting groove on the end cover body 2 includes an inner groove 31 and an outer groove 32. An inner stop block 23 is arranged in the inner groove 31, which is used to limit the insertion depth of the cover 4. Limiting steps 24 are formed on both sides of the outer groove 32, which are used to abut against the end of the blocking pin 44, so as to limit the movement of the cover 4 out of the connecting hole. The gap 33 is formed in the outer groove 32.

[0070] As shown in Figure 7 , the cover 4 abuts against the inner stop block 23. At this time, the cover 4 is in a self-locking state after being inserted into the end cover.

[0071] As Figure 3 And Figure 8 As shown in the figure, the inside of the scraper body 1 is hollow, and the inside is supported by a plurality of ribbons 11, and the end edge of the ribbon 11 is a flat end face. Since the cover 4 is installed between the end cover body 2 and the scraper body 1, the number of ribbons 11 near the cover 4 in the scraper body 1 is increased, and the increased ribbons 11 are used to abut the cover 4, when the cover 4 is in the open state, the cover 4 connecting part directly abuts the increased ribbons 11 here.

[0072] The increased ribbons 11 in the scraper body 1 are distributed longitudinally and transversely.

[0073] The putty scraper of the utility model, when the blade 5 needs to be replaced, referring to Figure 1 , first move the cover 4 downward, so that the blocking pin 44 of the cover 4 connecting part translates from the inner hole to the outer hole, then the cover 4 is turned upward, at this time the retreat blade opening is in the open state, that is Figure 2 As shown in the figure, at this time the old blade 5 is pulled out to the left, and a new blade 5 is reloaded, after the new blade 5 is inserted into the blade slot, the cover 4 is turned down to close the retreat blade slot 21, then the cover 4 is translated upward, so that the blocking pin 44 of the cover 4 translates into the inner hole, the cover 4 forms self-locking, at this time the cover 4 can effectively limit the displacement of the blade 5 in the blade slot.

[0074] The putty scraper of the utility model, the cover 4 is always on the scraper, and the opening and closing of the cover 4 do not need to rely on auxiliary tools, and the opening and closing of the cover 4 is very simple.
