As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0030] In the present utility model, unless otherwise clearly stipulated and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Embodiment 1:

[0032] like Figure 1-4 As shown, the AC angle grinder with dust-proof and shock-absorbing functions includes a housing 1 and a protective component 2 arranged on one side of the housing 1 .

[0033] The protective component 2 includes a protective cover 3 and a protective cover 2 5 rotatably connected to the inner wall of the protective cover 3, a paddle 4 is fixed to the outer wall of the protective cover 2 5, a receiving groove for receiving the paddle 4 is provided on the inner wall on one side of the protective cover 3, and a limiting component for limiting the position of the paddle 4 is provided on the inner wall on the other side of the protective cover 3, the limiting component includes two symmetrically arranged compression springs 6 and a limiting block 8, a sliding groove 13 is provided on the inner wall of the protective cover 3, the compression spring 6 is buckled on the opposite side of the limiting block 8 and the sliding groove 13, and the limiting block 8 is slidably fitted on the inner wall of the sliding groove 13.

[0034] When the device is used, the paddle 4 is used to drive the protective cover 2 5 to rotate along the protective cover 1 3 until the paddle 4 rotates to the limit block 8, and then the paddle 4 is used to push the two limit blocks 8 into the slide groove 13, and the compression spring 6 is elastically deformed under the force. When the paddle 4 passes the limit block 8, the paddle 4 is released, and the elastic action of the compression spring 6 is used to drive the limit block 8 to move outward, so that the two limit blocks 8 are used to limit the paddle 4, so that the protective cover 1 3 and the protective cover 2 5 can form a complete protective structure.

[0035] The device is provided with a protective cover 1 3 and a protective cover 2 5, and uses a paddle 4 to drive the protective cover 2 5 to rotate along the inner wall of the protective cover 1 3, and uses a limit block 8 to limit the paddle 4, so that the protective cover 1 3 and the protective cover 2 5 can form a complete protective structure, thereby reducing the risk of using the device.

[0036] like Figure 3 and Figure 4 As shown, the inner wall of the protective cover 3 is rotatably connected to two symmetrically arranged levers 9, and the inner walls at both ends of the levers 9 are provided with strip grooves 10. The limit block 8 is limited and fitted in one of the strip grooves 10 through a sliding rod 7 fixed on the top, and the inner wall of the protective cover 3 is provided with a guide groove 14 for guiding the sliding rod 7.

[0037] A second slide bar 11 is positioned in the other strip groove 10 , an adjusting block 12 is fixedly connected to the top of the second slide bar 11 , and a guide groove 15 for guiding the second slide bar 11 is provided on the inner wall of the protective cover 3 .

[0038] When the device needs to be used, while ensuring that the device is safely held, the two adjustment blocks 12 are pushed relative to each other using the thumb and index finger, and the slide bar 11 moves along the guide groove 15, so that the slide bar 17 drives the limit block 8 to slide into the slide groove 13 with the cooperation of the lever 9 and the strip groove 10. At this time, the paddle 4 is no longer restricted by the limit block 8, so that the paddle 4 can be used to rotate the protective cover 2 5 back into the protective cover 1 3, so that the grinding disc 19 is exposed and cutting and grinding work can be carried out.

[0039] like Figure 5 As shown, the protective cover 13 is rotatably connected to the inner wall of the shell 1 through a hollow shaft 18, a hollow shaft 17 is fixedly connected to the top of the protective cover 5, and the hollow shaft 17 is rotatably connected to the inner wall of the protective cover 3, and a volute spring 16 is buckled on the opposite side of the protective cover 5 and the hollow shaft 17.

[0040] When the paddle 4 drives the protective cover 2 5 to rotate, the hollow shaft 17 rotates synchronously with the protective cover 2 5, so that the volute spring 16 undergoes elastic deformation. When the paddle 4 is released, the volute spring 16 uses its own elasticity to drive the hollow shaft 17, the protective cover 2 5 and the paddle 4 to rotate and reset.

[0041] The protective cover 3 is rotatably connected to the shell 1 through the hollow shaft 2 18 and has a certain damping effect. Therefore, when using the device, the position of the protective cover 3 can be adjusted as needed, and the damping effect can be used to enable the protective cover 3 to maintain the current position unchanged, so that the protective cover 3 can be used to block some debris from flying and causing harm to the human body and achieve a certain dust-proof effect.

[0042] The device is provided with a spiral spring 16 and utilizes the elastic effect of the spiral spring 16. When the restriction of the limit block 8 on the paddle 4 is released by the adjustment block 12, the paddle 4 and the protective cover 2 5 can be driven to rotate and be retracted into the protective cover 1 3, thereby eliminating the need for manual adjustment, reducing the operating steps, and improving the convenience of use of the device.

[0043] like Figure 5 As shown, a motor 20 is fixed to the inner wall of the housing 1 by bolts, and a transmission shaft 21 is fixedly connected to the output end of the motor 20 via a coupling. The other end of the transmission shaft 21 passes through the protective cover 1 3 and the protective cover 2 5 in sequence and is fixedly connected to a grinding disc 19.

[0044] The starter motor 20 drives the transmission shaft 21 to drive the grinding disc 19 to rotate, so that grinding and beveling operations can be performed.

[0045] In this embodiment: when the device is in use, first hold the shell 1 tightly, then use the thumb and index finger to move the two adjustment blocks 12 relatively at the same time, so that the slide bar 11 moves along the guide groove 15, driving the lever 9 to rotate, thereby driving the limit block 8 to slide into the slide groove 13 under the cooperation of the strip groove 10 and the slide bar 1 7, and the compression spring 6 is elastically deformed under the force. At this time, the limit block 8 no longer restricts the paddle 4. Under the elastic action of the volute spring 16, the paddle 4 and the protective cover 2 5 are rotated and retracted into the protective cover 1 3, so that part of the structure of the grinding disc 19 is exposed, and then the motor 20 is started to drive the transmission shaft 21 to drive The grinding disc 19 rotates at high speed to perform cutting and grinding work; after use, turn off the motor 20 and after the grinding disc 19 stops rotating completely, hold the paddle 4 to drive the protective cover 2 5 and the hollow shaft 17 to rotate, so that the spiral spring 16 undergoes elastic deformation, and when the paddle 4 rotates to the limit block 8, the paddle 4 is used to squeeze the limit block 8 into the slide groove 13, and the paddle 4 is released after passing the limit block 8. The compression spring 6 uses its own elasticity to push the limit block 8 to move outward, thereby restricting the paddle 4. At this time, the protective cover 1 3 and the protective cover 2 5 form a complete protective structure to reduce the danger of the device. Embodiment 2:

[0046] The AC angle grinder with dust and shock absorbing function, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 6 As shown:

[0047] An auxiliary handle 22 is fixedly connected to the outer wall of one side of the housing 1, and a shock-absorbing sleeve 23 is wrapped around the outer wall of the housing 1. The shock-absorbing sleeve 23 can be a rubber sleeve or a sponge sleeve.

[0048] By providing an auxiliary handle 22, the device can be used to control the direction and position of the device by holding the shell 1 with one hand, and to stabilize the device by holding the auxiliary handle 22 with the other hand, thereby ensuring balance and control during operation and reducing the possibility of injury. The shock-absorbing sleeve 23 has a certain shock-absorbing effect on the device, thereby reducing the fatigue caused by vibration to the user and facilitating efficient operation.

[0049] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
