[0022] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0023] 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.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the shovel head provided in this embodiment includes a shovel head body 100, a protective sleeve 200, and a drive mechanism 300 mounted on the shovel head body 100. The front end of the shovel head body 100 has a mounting groove 110, within which a blade mounting portion 120 is provided. A blade 130 is mounted on the blade mounting portion 120, extending out of the mounting groove 110. The blade mounting portion 120 has clearance channels 140 on both sides in the width direction of the shovel head, meaning that the periphery of the blade mounting portion 120 has space for the protective sleeve 200 to be fitted and moved. The protective sleeve 200 has a receiving groove 210 with a first opening 220. The bottom wall of the receiving groove 210 opposite to the first opening 220 has a gap 230 for the blade 130 to enter and exit. The protective sleeve 200 is fitted onto the blade mounting portion 120. The drive mechanism 300 is connected to the protective sleeve 200. The drive mechanism 300 drives the protective sleeve 200 to switch between a protective position and a working position. When the protective sleeve 200 is in the protective position, it covers the blade 130; when the protective sleeve 200 is in the working position, it exposes the blade 130. That is to say, as... Figure 2 As shown, when the sheath 200 is in the protective position, it extends out of the mounting groove 110 and covers the blade 130, thus preventing the blade 130 from being exposed and scratching the user or objects. When using the scraper, the operating drive mechanism 300 drives the sheath 200 to switch from the protective position to the working position, as shown. Figure 3 As shown, at this time, the sheath 200 retracts into the mounting groove 110 (it can be partially exposed or completely retracted into the mounting groove 110), exposing the blade 130, thus allowing the user to use the scraper for work. The scraper head provided in this embodiment does not require the sheath 200 to be removed independently when using the scraper, solving the technical problem that the sheath 200 is easily lost. Furthermore, the retractable operation of the sheath 200 provided in this embodiment is convenient and easy to use.

[0025] In some embodiments of this application, the shovel head body 100 includes a first shovel head body 150 and a second shovel head body 160, which are detachably connected. The blade mounting part 120 includes a first mounting part 121 and a second mounting part 122, where the first mounting part 121 is connected to the first shovel head body 150 and the second mounting part 122 is connected to the second shovel head body 160. The blade 130 is mounted between the first mounting part 121 and the second mounting part 122.

[0026] For example, the first shovel head body 150 and the second shovel head body 160 are detachably connected by fasteners (not shown in the figure), which pass through the first mounting portion 121 and the second mounting portion 122, so that the blade 130 is pressed or connected between the first mounting portion 121 and the second mounting portion 122.

[0027] In some embodiments of this application, the sheath 200 is a soft rubber sleeve. The soft rubber sleeve can better fit with the blade 130 and better fit with the inner wall of the shovel head body 100, reducing the amount of dust and particles from the shovel scraper getting stuck between the sheath 200 and the blade 130, and reducing the amount of dust and particles from the shovel scraper getting stuck between the sheath 200 and the inner wall of the shovel head body 100.

[0028] For example, in order to further increase the fit between the soft rubber sleeve and the blade 130, and the fit between the soft rubber sleeve and the inner wall of the shovel head body 100, the opening edge of the mounting groove 110 is provided with a raised pressure strip. After the fasteners securely connect the first shovel head body 150 and the second shovel head body 160, the raised pressure strip squeezes the soft rubber sleeve, so that the soft rubber sleeve fits better on the blade 130.

[0029] In some embodiments of this application, in order to reduce the deflection of the sheath 200 when switching from the protective position to the working position, the side wall of the mounting groove 110 is provided with a limiting protrusion. When the sheath 200 is in the working position, the side of the sheath 200 on the first opening 220 side abuts against the limiting protrusion. That is, when the sheath 200 switches from the protective position to the working position, if one side switches to the position first, the limiting protrusion will abut against the side of the sheath 200 that is in position first, thereby correcting the portion of the sheath 200 that is in position later.

[0030] In this embodiment, for ease of operation, a portion of the drive mechanism 300 is located on the outside of the shovel head body 100, and another portion extends into the mounting groove 110 and connects to the protective sleeve 200. Exemplarily, in some embodiments of this application, the drive mechanism 300 includes a pusher 310, which is mounted on the shovel head body 100. A portion of the pusher 310 is located on the outside of the shovel head body 100, and another portion extends into the mounting groove 110 and connects to the protective sleeve 200. The pusher 310 is movable between a first position and a second position. When the pusher 310 is in the first position, the protective sleeve 200 is in a protective position. When the pusher 310 moves from the first position to the second position, it drives the protective sleeve 200 to move from the protective position to the working position. That is, the first position of the pusher 310 corresponds to the protective position of the protective sleeve 200, and the second position of the pusher 310 corresponds to the working position of the protective sleeve 200. In this embodiment, the sheath 200 is switched between the protective position and the working position by pushing the pusher 310 between the first position and the second position. The operation is simple and convenient.

[0031] In some embodiments of this application, such as Figure 5 As shown, the pusher 310 includes a pusher 310 body and a connecting post 312. The connecting post 312 connects the pusher 310 body and the sheath 200. The connecting post 312 is a metal post, which is not easily deformed or broken, and is conducive to pushing the sheath 200 to move.

[0032] Exemplary examples, in some embodiments of this application, such as Figure 3 and Figure 5 As shown, the shovel head body 100 is provided with a guide mounting hole 151, which passes through the outer side of the shovel head body 100 and the mounting groove 110. The pusher 310 is provided with two opposing snap-fit ​​arms 313. The free end of the snap-fit ​​arm 313 is provided with a snap protrusion 314. The snap-fit ​​arm 313 extends from the guide mounting hole 151 into the mounting groove 110. The snap protrusion 314 and the pusher 310 respectively abut against the two axial edges of the guide mounting hole 151, so that the pusher 310 is installed in the guide mounting hole 151 and moves along the guide mounting hole 151. In other words, the pusher 310 extends into the mounting groove 110 from the guide mounting hole 151 by the deformation of the two snap-fit ​​arms 313. After the snap-fit ​​arms 313 extend into the mounting groove 110, they restore their deformation so that the snap-fit ​​protrusion 314 abuts against the side wall of the mounting groove 110 located around the guide mounting hole 151. This allows the pusher 310 to snap into the guide mounting hole 151 and move along the guide mounting hole 151.

[0033] This application also provides a shovel, which includes a handle and a shovel head according to any of the above embodiments, with the shovel head connected to the handle.
