In order to achieve the above object, the utility model provides a following technical scheme:

a scratch-proof scraper knife comprises a scraper knife body, the scraper knife body comprises a scraper knife blade, and further comprises a limiting block, an elastic sheet, a pushing block and a protective shell, the protective shell is provided with two opposite sides, one of the opposite sides is respectively bent to form an accommodating part, the other opposite side is respectively provided with a first open end part and a second open end part, the limiting block, the elastic sheet and the scraper knife blade are sequentially arranged in the protective shell, the limiting block is fixed in the first open end part, the two ends of the elastic sheet respectively form a fixed end and a connecting end, the protective shell forms a positioning hole corresponding to the fixed end, the scraper knife blade forms a pin hole and a scraper knife blade groove, at least part of the elastic sheet is clamped in the scraper knife blade groove and forms positioning connection with the pin hole through the connecting end, the pushing block is fixed on the upper side surface of the scraper knife blade, one side of the pushing block, which, the blade is driven by the push block to extend out of the second open end.

Preferably, the receiving portions are symmetrically arranged.

Preferably, the limiting block is provided with a slot, and at least part of the elastic sheet is accommodated in the slot.

Preferably, the transverse cross-sectional area of the positioning lug is 1/3-3/4 of the area of the pin hole.

Preferably, the pushing block is provided with a pushing part, and the pushing part at least partially protrudes out of the protective shell.

The utility model discloses a set up protective housing structure, release the shovel blade through the ejector pad during use, in the time spent not automatic return protective housing, be difficult for taking place the fish tail, and because protective housing's existence, the ground back shovel blade that drops also can not take place to damage.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, a scratch-proof scraper knife comprises a scraper knife body 1, the scraper knife body 1 comprises a limiting block 2, an elastic sheet 3, a pushing block 4, a scraper blade 5 and a protective casing 6, the protective casing 6 is rectangular and has two opposite sides, one of the two opposite sides is respectively bent to form an accommodating part 62, preferably, the accommodating part 62 is symmetrically arranged, the other opposite side is respectively formed with a first open end 63 and a second open end 64, the first open end 63 is used for forming a stop for the scraper blade 5, the second open end 64 is used for extending the scraper blade 5, specifically, the limiting block 2, the elastic sheet 3 and the scraper blade 5 are sequentially arranged inside the protective casing 6, the limiting block 2 is fixed on the first open end 63 in a tight fit manner, so as to form a stop for the scraper blade 5, in the utility model, the limiting block 2 is provided with a slot 21, the elastic sheet 3 is at least partially accommodated in the slot, thereby making the whole structure more compact, the two ends of the elastic sheet 3 respectively form a fixed end 31 and a connecting end 32, the elastic sheet 3 is configured to have a restoring force for providing the shovel blade 5 to automatically return to the protective shell 6, the surface of the protective shell 6 forms a positioning hole 61 corresponding to the fixed end 31, the fixed end 31 is tightly matched and connected with the positioning hole 61, the shovel blade 5 forms a pin hole 51 and a blade groove 511, the pin hole 51 and the blade groove 511 are arranged in a communicating way, the width of the blade groove 511 corresponds to the thickness of the elastic sheet 3, the connecting end 32 forms a cylinder, the diameter of the cylinder is larger than the width of the blade 511, thereby the connecting end 32 can not slip from the blade groove 511 after the installation of the elastic sheet 3, at least part of the elastic sheet 3 is clamped in the blade groove 511 and forms a positioning connection with the pin hole 51 through the connecting end 32, the push block 4 is fixed on the upper side surface of the shovel blade 5, the push block 4 has a pushing, the positioning projection 42 is tightly fitted and fixed with the pin hole 51, and the transverse cross-sectional area of the positioning projection 42 is 1/3-3/4 of the area of the pin hole 51, so as to provide a containing space for the connecting end 32, in order to apply pushing force, the pushing part 41 at least partially protrudes from the protective shell 6, and the shovel blade 5 extends out of the second open end 64 when the pushing part 41 is pushed.

The working principle is as follows: when the deburring device is used for deburring, the pushing part 41 is pushed, the shovel blade 5 extends out of the second open end part 64, when the deburring device is used continuously, pushing force needs to be continuously applied, after the deburring treatment is completed, the pushing block 4 is released, and the shovel blade 5 automatically returns to the protective shell 6 under the action of the elastic sheet 3.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
