[0029] It should be noted that the “long axis direction” in this application text is the Figure 1 The direction of the a-axis is marked in the figure, and the “minor axis direction” is the direction of the attached Figure 1 The terminology used in the specification of the present invention is only for the purpose of describing specific embodiments and is not intended to limit the present invention.

[0030] The technical solution of the present utility model will be described below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 to Figure 4As shown, the electric tool in one embodiment of the utility model comprises: a housing 1 and a dust screen 4. An air inlet plate 2 is provided inside the housing 1, and an air inlet hole 21 and a buckle 22 arranged along the axial direction are provided on the air inlet plate 2. A plurality of abutment ribs 3 are extended inwardly on the inner wall of the housing 1, and the buckle 22, the abutment rib 3, the housing 1, and the air inlet plate 2 are enclosed to form a clamping groove; a groove 40 is provided on the dust screen 4 to match the buckle 22, and the dust screen 4 is clamped in the clamping groove. When assembling, insert from the side provided with the buckle 22, fix through the abutment rib 3, and finally press the dust screen 4 downward through the buckle 22 and the groove 40 to clamp the dust screen 4 in the clamping groove. According to this design, the traditional method of using screws, screws, bolts and other fasteners to fix the dustproof net 4 can be replaced. The dustproof net 4 can be assembled on the shell 1 through the buckle 22 and the abutment rib 3, thereby reducing the installation time and the use of fasteners and other parts. The risk of being unable to install the dustproof net 4 due to their loss can be avoided, thereby saving costs.

[0032] Specifically, refer to Figure 3 , Figure 4 As shown, the dustproof net 4 in this embodiment includes a support portion 41 and a dustproof portion 42 located in the support portion 41, and the support portion 41 abuts against the abutting rib 3 and is snapped with the buckle 22. According to this design, it is possible to prevent the abutting rib 3 from covering the dustproof portion 42 and affecting the air intake effect of the power tool. Among them, the unit porosity of the dustproof portion 42 in this embodiment is 50% to 80%. Preferably, the unit porosity of the dustproof portion 42 is 67%. At this time, the flexibility and dustproof effect of the dustproof net 4 are better.

[0033] Reference Figure 3 , Figure 4 As shown, the support portion 41 in this embodiment includes a first main body portion 411 and a second main body portion 412 arranged oppositely along the long axis direction, and a third main body portion 413 and a fourth main body portion 414 arranged oppositely along the short axis direction, wherein the third main body portion 413 and the fourth main body portion 414 are arranged symmetrically, the angle formed by the line connecting the two ends of the first main body portion 411 and the center of the dustproof net 4 is 80°, the angle formed by the line connecting the two ends of the third main body portion 413 and the center of the dustproof net 4 is 100°, and the angle formed by the line connecting the end of the first main body portion 411 away from the third main body portion 413 and the end of the third main body portion 413 away from the first main body portion 411 and the center of the dustproof net 4 is 180°. The groove 40 in this embodiment is provided on one of the first main body portion 411 and the second main body portion 412, and the abutting rib 3 is at least provided and abuts against the other of the first main body portion 411 and the second main body portion 412. According to this design, during the snap-in process, since the dustproof net 4 is flexible, the dustproof net 4 will bend and deform preferentially along the short axis direction. According to this design, it is easy to snap-in the groove 40 with the buckle 22, saving time and effort.

[0034] Optional, see Figure 3 , Figure 4 As shown, the groove 40 in this embodiment is provided on the first main body portion 411, and the abutting rib 3 includes a first abutting rib 31 abutting against the second main body portion 412. Exemplarily, two first abutting ribs 31 are provided. Of course, the present application is not limited thereto, and the groove 40 may also be provided on the second main body portion 412, and the abutting rib 3 includes a first abutting rib 31 abutting against the first main body portion 411. The first abutting rib 31 may also be one, three, or more. According to this design, the dust screen 4 can be fixed to the housing 1 by the buckle 22 and the first abutting rib 31.

[0035] Preferably, in order to more securely fix the dust screen 4 on the housing 1, refer to Figure 3 , Figure 4 As shown, the abutting rib 3 in this embodiment also includes a second abutting rib 32 abutting against the third main body portion 413 and / or the fourth main body portion 414. Exemplarily, there are two second abutting ribs 32 and they are symmetrically arranged along the long axis direction of the dustproof net 4, and the two second abutting ribs 32 abut against the third main body portion 413 and the fourth main body portion 414 respectively. Of course, the present application is not limited to this, and the second abutting rib 32 can also be multiple, at least one of which abuts against the third main body portion 413, and at least one abuts against the fourth main body portion 414.

[0036] Further, see Figure 3 , Figure 4 As shown, the angle formed by the line connecting the buckle 22 and the first abutting rib 31 and the center of the dustproof net 4 in this embodiment is 140° to 180°. The angle formed by the line connecting the buckle 22 and the second abutting rib 32 and the center of the dustproof net 4 is 90° to 120°. According to this design, the first abutting rib 31 can prevent the dustproof net 4 from being slightly deformed during the clamping process, which causes the second main body 412 to tilt. The second abutting rib 32 can prevent the dustproof net 4 from being excessively deformed and causing plastic deformation.

[0037] Reference Figure 2 As shown, the buckle 22 in this embodiment includes a connecting arm 221 connected to the air inlet plate 2 and a clamping portion 222 provided on the connecting arm 221. The clamping portion 222 is provided with a guide surface 2221, and the guide surface 2221 gradually tilts outward from the air inlet plate 2 to the dust screen 4. According to this design, when the dust screen 4 is inserted in one direction, the dust screen 4 abuts against the inner wall of the shell 1 and then presses the dust screen 4 downward. The guide surface 2221 can convert the downward movement of the dust screen 4 into a movement trend along the long axis direction toward the inner wall of the shell 1. Since the dust screen 4 has abutted against the inner wall of the shell 1, the dust screen 4 will be slightly deformed, so that the buckle 22 is easily engaged with the groove 40.

[0038] Furthermore, in order to smoothly assemble the dust screen 4 on the shell 1 , the distance between the inner wall of the connecting arm 221 and the inner wall of the shell 1 in this embodiment is greater than the distance between the bottom wall of the groove 40 and the inner wall of the shell 1 .

[0039] Reference Figure 2 As shown, there is a gap between the buckle 22 in this embodiment and the inner wall of the housing 1. According to this design, the buckle 22 can be slightly deformed outward, which makes it easier to engage the buckle 22 and the groove 40, saving time and effort. At the same time, it can prevent the dust screen 4 from being deformed too much during the engagement between the buckle 22 and the groove 40.

[0041] The utility model provides an electric tool which can replace the traditional method of using screws, screws, bolts and other fasteners to fix the dustproof net. The dustproof net can be assembled on the shell through buckles and abutment ribs, which reduces the installation time and the use of parts such as fasteners, avoids the risk of being unable to install the dustproof net due to loss, and saves costs.
