[0002] As a common hand tool, scrapers are widely used in construction and decoration, household cleaning and other fields to scrape off old paint, putty, glue stains, dirt and other attachments on walls.

[0003] like Figure 1 As shown, a scraper 100 typically includes a handle 110 and a scraper head 120 connected to the handle 110. A blade 130 is mounted on the front end of the scraper head 120. The scraper head 120 includes a scraper head body 125 and a pressing body 126. The pressing body 126 is detachably mounted on the first side of the scraper head body 125. The blade 130 is mounted between the scraper head body 125 and the pressing body 126. The blade 130 has a sharp edge to ensure good scraping performance. To ensure safety during transportation and storage, and to prevent the sharp blade 130 from causing personal injury or scratching other objects, the scraper 130 is typically equipped with a protective sleeve. In related technologies, the protective sleeve on a scraper is usually directly fitted onto the front end of the scraper head to protect the blade. During use, the operator removes the protective sleeve directly from the front end of the scraper head, and after the work is completed, the protective sleeve is put back onto the front end of the scraper head to protect the blade.

[0004] However, the protective cases in these technologies are prone to being lost. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] like Figure 1 and Figure 2 As shown, the shovel 100 in this embodiment includes a handle 110 and a shovel head 120 connected to the handle 110. The shovel head 120 and the handle 110 can be an integrally formed structure or a detachably connected structure. A blade 130 is installed at the front end of the shovel head 120. The shovel head 120 includes a shovel head body 125 and a pressing body 126. The pressing body 126 is detachably installed on the first side of the shovel head body 125. The blade 130 is installed between the shovel head body 125 and the pressing body 126. The shovel head 120 ... in the thickness direction (e.g., ...). Figure 1 Decorative grooves 121 are provided on both sides of the shovel head 120 in the Z direction. The decorative grooves 121 have a front side and a side in the width direction of the shovel head 120 (e.g., in the Z direction). Figure 1 On both sides of the Y direction, the front end of the shovel head 120 where the blade is mounted is wider and narrows at the rear end near the handle 110. The two sides of the shovel head 120 near the handle 110 are arc-shaped in the width direction. The front end of the shovel head 120 narrows at the rear end through the arc-shaped edge. The two outer arc-shaped edges of the shovel head 120 near the handle 110 are the first side 123 and the second side 124, respectively.

[0031] It should be noted that the structural form of the scraper 100 is not limited to... Figure 1 and Figure 2 The structure can be any other form, and no specific limitation is made here. Example 1

[0032] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the protective sleeve 300 for the shovel 100 provided in this embodiment includes a first housing 210, a second housing 220, a sleeve 300, and a drive mechanism 400. The first housing 210 has a pressing part 211, and an installation space 212 exists between the pressing part 211 and the first housing 210. The pressing part 211 has clearance channels 213 on both sides of the width direction of the shovel head 120 body of the shovel 100. The clearance channels 213 communicate with the installation space 212 and make way for the sleeve 300, allowing it to be fitted onto the pressing part 211. The first housing 210 is configured to be installed on the first side of the shovel head 120 body of the shovel 100, and the pressing part 211 cooperates with the shovel head 120 body to press the blade 130. In other words, in this embodiment, the first housing 210 of the shovel 100 protective sleeve 300 replaces the pressing body 126 of the shovel head 120 and presses the blade 130 in cooperation with the shovel head 120 body. This arrangement facilitates the operation of changing the blade 130 of the shovel 100 and facilitates the assembly of the shovel 100 equipped with the shovel 100 protective sleeve 300.

[0033] In this embodiment, the sheath 300 has a receiving groove 310 with a first opening 320. The bottom wall of the receiving groove 310 opposite to the first opening 320 is provided with a gap 330 for the blade 130 of the shovel 100 to enter and exit. When the shovel 100 protective sheath 300 is installed on the shovel head 120 body, the sheath 300 is also fitted onto the shovel head 120 body portion that is fitted onto the pressing part 211 and the portion of the shovel head 120 body corresponding to the pressing part 211. The drive mechanism 400 is installed on the first housing 210 or the second housing 220. The drive mechanism 400 extends into the mounting space 212 corresponding to the first housing 210 and connects with the protective sleeve 300, or extends into the second housing 220 and connects with the protective sleeve 300. That is, when the drive mechanism 400 is installed on the first housing 210, it extends into the mounting space 212 and connects with the protective sleeve 300; when the drive mechanism 400 is installed on the second housing 220, it extends into the second housing 220 and connects with the protective sleeve 300. In this embodiment, the drive mechanism 400 drives the protective sleeve 300 to switch between a protective position and a working position. When the protective sleeve 300 is in the protective position, it covers the blade 130; when the protective sleeve 300 is in the working position, it exposes the blade 130. In other words, when the protective sleeve 300 of the shovel 100 provided in this embodiment is installed on the shovel 100, as... Figure 6 As shown, when the shovel 100 is in use, the drive mechanism 400 drives the sheath 300 to move backward so that the sheath 300 is in the working position, at which time the blade 130 is exposed, as shown. Figure 5 As shown, when the scraper 100 is not in use, the drive mechanism 400 drives the protective sleeve 300 to move forward so that the protective sleeve 300 is in a protective position. At this time, the blade 130 is covered to prevent the blade 130 from being exposed and scratching the user or objects. The protective sleeve 300 of the scraper 100 provided in this embodiment does not need to be removed separately when the scraper 100 is in use, which solves the technical problem that the protective sleeve 300 of the scraper 100 is easy to be lost.

[0034] In some embodiments of this application, the first housing 210, the pressing part 211, and the second housing 220 are provided with a second mounting hole 214 corresponding to the mounting hole 127 of the shovel head 120 body. The fastener 500 is installed in the mounting hole 127 and the second mounting hole 214 to securely connect the first housing 210, the blade 130, the shovel head 120 body, and the second housing 220. That is, the first housing 210 and the second housing 220 are detachably connected by the fastener 500. When the blade 100 protective sleeve 300 is installed on the shovel head 120 body, the fastener 500 simultaneously connects the pressing part 211 and the shovel head 120 body so that the blade 130 is pressed or connected between the pressing part 211 and the shovel head 120 body. In this embodiment, the blade 130 can be pressed between the press-fitting part 211 and the shovel head 120 body by connecting the press-fitting part 211 and the shovel head 120 body. Alternatively, the fastener 500 can pass through the blade 130 simultaneously, connecting and pressing the blade 130 between the press-fitting part 211 and the shovel head 120 body. When the protective sleeve 300 of the shovel 100 in this embodiment is installed on the shovel head 120 body, the connection position of the first housing 210 and the second housing 220 corresponds to the connection position of the shovel head 120 body and the press-fitting part, which facilitates the replacement of the press-fitting part by the first housing 210 and facilitates the cooperation between the first housing 210 and the shovel head 120 body to securely connect the blade 130.

[0035] like Figure 3 , Figure 7 and Figure 8 As shown, in some embodiments of this application, at least one of the first housing 210 and the second housing 220 is provided with a limiting structure 240, the limiting structure 240 being configured to restrict the first housing 210 and the second housing 220 in the length direction of the scraper 100 (e.g., ...). Figure 6 (in the X direction) and / or the width direction of the shovel head 120 (e.g.) Figure 6 The first housing 210 and the second housing 220 are configured to restrict the position of the first housing 210 and the second housing 220 in the length direction of the blade 100 and the width direction of the blade head 120, or the first housing 210 and the second housing 220 are configured to restrict the position of the first housing 210 and the second housing 220 in the length direction of the blade 100, or the first housing 210 and the second housing 220 are configured to restrict the position of the first housing 210 and the second housing 220 in the width direction of the blade head 120.

[0036] In some embodiments of this application, exemplarily, such as Figure 8As shown, the limiting structure 240 includes a first limiting structure 241, which is disposed within the second housing 220. The first limiting structure 241 includes a first limiting surface 242, a second limiting surface 243, and a third limiting surface 244. The first limiting surface 242 is at least partially in contact with the front sidewall 122 of the decorative groove 121. The first limiting surface 242 and the front sidewall 122 of the decorative groove 121 cooperate to limit the position of the second housing 220 in the length direction of the blade 100. The second limiting surface 243 and the third limiting surface 244 respectively contact the two sidewalls of the decorative groove 121 in the width direction of the blade 120. The second limiting surface 243 and the third limiting surface 244 fit with the two side walls of the decorative groove 121 in the width direction of the shovel head 120, at least partially, to restrict the position of the second housing 220 in the width direction of the shovel head 120, so that the second housing 220 will not wobble in the width direction of the shovel head 120. In addition, the two side walls of the decorative groove 121 in the width direction of the shovel head 120 are arc-shaped surfaces, and the fit between the second limiting surface 243 and the third limiting surface 244 and the two side walls of the decorative groove 121 in the width direction of the shovel head 120 can also restrict the position of the second housing 220 in the length direction of the shovel blade 100.

[0037] like Figure 3 As shown, the limiting structure 240 may further include a second limiting structure 245. The second limiting structure 245 includes a first protruding edge 246 and a second protruding edge 247. The first protruding edge 246 is at least partially in contact with the first side 123 of the shovel head 120, and the second protruding edge 247 is at least partially in contact with the second side 124 of the shovel head 120. The first protruding edge 246 and the second side 124 cooperate, and the second protruding edge 247 and the second side 124 cooperate to define the positions of the first housing 210 and the second housing 220 in the length direction of the shovel blade 100 and the width direction of the shovel head 120.

[0038] For example, such as Figure 3 and Figure 8 As shown, in this embodiment, the second limiting structure 245 is disposed on the first housing 210, and the first limiting structure 241 is disposed on the second housing 220. The second limiting structure 245 is provided with multiple card slots 248, and the inner sidewall of the second housing 220 is provided with buckles 221 corresponding to each card slot 248. The second housing 220 and the first housing 210 are engaged through the cooperation of the buckles 221 and the card slots 248. In other words, the second limiting structure 245 serves both as a limiting mechanism and as a locking structure for the buckles 221. The card slots 248 are located on the second limiting structure 245, facilitating the disassembly of the first housing 210 and the second housing 220.

[0039] In some embodiments of this application, the sheath 300 is a soft rubber sleeve. The soft rubber sleeve can better fit with the blade 130 and better fit with the inner walls of the first housing 210 and the second housing 220, reducing the amount of dust and particles scraped by the scraper 100 that get stuck between the sheath 300 and the blade 130, and also reducing the amount of dust and particles scraped by the scraper 100 that get stuck between the sheath 300 and the inner walls of the first housing 210 and the second housing 220.

[0040] like Figure 8 As shown, in order to further increase the fit between the soft rubber sleeve and the blade 130, as well as the fit between the soft rubber sleeve and the inner walls of the first housing 210 and the second housing 220, the edges of the first housing 210 and the second housing 220 corresponding to the side where the soft rubber sleeve is installed are provided with raised pressure strips 250. After the first housing 210 and the second housing 220 are connected, the raised pressure strips 250 squeeze the soft rubber sleeve, so that the soft rubber sleeve fits better on the blade 130.

[0041] In some embodiments of this application, in order to reduce the deflection of the sheath 300 when switching from the protective position to the working position, the inner wall of the second housing 220 is provided with a limiting protrusion 260. When the sheath 300 is in the working position, the side of the sheath 300 on the first opening 320 side abuts against the limiting protrusion 260. That is, when the sheath 300 switches from the protective position to the working position, if one side switches to the position first, the limiting protrusion 260 will abut against the side of the sheath 300 that switches to the position first, thereby correcting the portion of the sheath 300 that switches to the position later.

[0042] In some embodiments of this application, such as Figure 8 and Figure 9 As shown, to prevent the sheath 300 from moving backward due to accidental contact and exposing the blade 130, the inner wall of the first housing 210 or the second housing 220 is provided with a retaining protrusion 270, and the sheath 300 is provided with a retaining arm 340 at the outer edge of the first opening 320. When the sheath 300 is in the protective position, the retaining arm 340 abuts against the side of the retaining protrusion 270 closest to the sheath 300. When the sheath 300 switches from the protective position to the working position, the retaining arm 340 deforms and disengages from the retaining protrusion 270. In other words, when the sheath 300 is in the protective position, the retaining arm 340 abuts against the retaining protrusion 270 to prevent the sheath 300 from retracting into the first housing 210 and the second housing 220 due to accidental contact by the user, thus preventing the blade 130 from being exposed. When the sheath 300 switches from the protective position to the working position, the drive mechanism 400 drives the sheath 300 to switch positions. At this time, the blocking arm 340 is deformed by force. The end of the blocking arm 340 that abuts against the blocking protrusion 270 passes the abutment point between the two and disengages from the abutment with the blocking protrusion 270. When the sheath 300 switches back to the protective position, the blocking arm 340 restores its deformation and resumes abutment with the blocking protrusion 270.

[0043] In this embodiment, as Figure 7 and Figure 10 As shown, in some embodiments of this application, the drive mechanism 400 includes a pusher 410, which is mounted on the first housing 210 or the second housing 220. The pusher 410 extends into the mounting space 212 corresponding to the first housing 210 and connects to the sheath 300, or extends into the second housing 220 corresponding to the second housing 220 and connects to the sheath 300. That is, when the pusher 410 is mounted on the first housing 210, a portion of the pusher 410 is located outside the first housing 210, and a portion extends into the mounting space 212 and connects to the sheath 300. When the pusher 410 is mounted on the second housing 220, a portion of the pusher 410 is located outside the second housing 220, and a portion extends into the second housing 220 and connects to the sheath 300. The pusher 410 is movable between a first position and a second position. When the pusher 410 is in the first position, the sheath 300 is in the protective position. When the pusher 410 moves from the first position to the second position, it drives the sheath 300 to move from the protective position to the working position. In other words, the first position of the pusher 410 corresponds to the protective position of the sheath 300, and the second position of the pusher 410 corresponds to the working position of the sheath 300. This embodiment achieves the switching between the protective position and the working position of the sheath 300 by pushing the pusher 410 between the first and second positions, making the operation simple and convenient.

[0044] For example, such as Figure 8 As shown, the pusher 410 is installed on the second housing 220. The second housing 220 is provided with a guide mounting hole 280, which penetrates the inner and outer sides of the second housing 220. The pusher 410 is provided with two opposing snap-fit ​​arms 411. The free end of the snap-fit ​​arm 411 is provided with a snap protrusion 412. The snap-fit ​​arm 411 extends into the second housing 220 from the guide mounting hole 280. The snap protrusion 412 and the pusher 410 respectively abut against the two axial edges of the guide mounting hole 280, so that the pusher 410 is installed in the guide mounting hole 280 and moves along the guide mounting hole 280. In other words, the pusher 410 extends into the second housing 220 from the guide mounting hole 280 by the deformation of the two snap-fit ​​arms 411. After the snap-fit ​​arms 411 extend into the second housing 220, they restore their deformation so that the snap-fit ​​protrusions 412 abut against the axial edges of the guide mounting hole 280, thereby making the pusher 410 snap into the guide mounting hole 280 and able to move along the guide mounting hole 280.
