[0026] like Figures 1 to 7As shown, an auxiliary handle 1 in one embodiment of the utility model is used for an angle grinder, and the angle grinder is provided with a pressure plate. The auxiliary handle 1 includes a handle body 11 and a functional component. The functional component is used to adjust the tightness of the pressure plate of the angle grinder, and the functional component includes a connecting member 12, a protruding member 13 and a connecting plate 14. The connecting plate 14 is arranged in the handle body 11, and is respectively connected to the connecting member 12 and the protruding member 13. The connecting member 12 is used to be detachably connected to the angle grinder, and the connecting member 12 is partially arranged in the handle body 11 and partially protrudes from the handle body 11. The connecting member 12 and the angle grinder can be connected by threaded connection, pin connection, clamping and other connection methods, and the operator can select the corresponding connecting member 12 according to different connection methods. For example, when threaded connection is adopted, the connecting member 12 can be a bolt, and a corresponding threaded hole is set on the angle grinder. Of course, the connecting member 12 can also be set in the form of a threaded hole, and a bolt is set on the angle grinder. The protruding piece 13 is used to engage with the pressing plate of the angle grinder. The protruding piece 13 is partially arranged inside the handle body 11 and partially protrudes outside the handle body 11. The pressing plate has two inner and outer plates, which are connected together by threads. The tightness of the pressing plate can be adjusted by rotating the outer plate. Therefore, in order for the protruding piece 13 to be able to engage with the pressing plate, a corresponding hole needs to be provided on the pressing plate for the protruding piece 13 to be inserted. After the two are combined, the operator can rotate the auxiliary handle 1 to drive the outer plate of the pressing plate to rotate, thereby adjusting the tightness of the pressing plate.

[0027] It can be seen from the above embodiments that after the angle grinder is equipped with the auxiliary handle 1, the operator can hold the auxiliary handle 1 to assist in supporting the angle grinder when using the angle grinder, and after the auxiliary handle 1 is removed, the protruding piece 13 can be combined with the pressing plate of the angle grinder to adjust the tightness of the pressing plate. In addition, the connection method of the connecting plate 14 and the embedding of the handle body 11 can make the connecting piece 12, the protruding piece 13 and the handle body 11 form an integrated structure, improve the connection strength of the connecting piece 12 and the protruding piece 13 with the handle body 11, and avoid the connecting piece 12 and the protruding piece 13 being damaged or separated from the handle body 11 due to excessive force during use.

[0028] In one embodiment, if Figure 6 and Figure 7 As shown, the auxiliary handle 1 is connected to other parts of the angle grinder by threaded connection, and the connecting member 12 is configured as a bolt, the head of the bolt is embedded in the auxiliary handle 1 and fixedly connected to the connecting plate 14 , and can be specifically welded to the connecting plate 14 .

[0029] In one embodiment, the protruding member 13 is a columnar protruding nail, one end of which is fixedly connected to the connecting plate 14, specifically, it can be welded to the connecting plate 14, and the other end of the protruding nail protrudes from the handle body 11. The cross section of the protruding member 13 perpendicular to the shaft portion can be set to any shape, such as circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal and other regular or irregular shapes.

[0030] Furthermore, when the cross section of the protruding nail perpendicular to the shaft portion is set to be circular, at least two protruding pieces 13 are required to rotate the pressure plate of the angle grinder, wherein providing two protruding pieces 13 is a preferred solution.

[0031] In one embodiment, after the connecting piece 12, the protruding piece 13 and the connecting plate 14 are welded together to form a functional component, in order to embed the functional component as a whole into the handle body 11, it can be embedded into the handle body 11 through an injection molding process to achieve a stable connection between the functional component and the handle body 11.

[0032] In one embodiment, if Figure 5 and Figure 6 As shown, the handle body 11 includes a gripping portion 111 and a connecting portion 112. The connecting portion 112 is coaxially arranged at one end of the gripping portion 111. The connecting portion 112 is axially provided with a first through hole 1121 for the connecting member 12 to pass through. The first through hole 1121 is directly formed during the injection molding of the handle body 11.

[0033] In order to facilitate processing and forming, the connecting portion 112 is a plate or a plurality of stacked plates. The maximum cross-sectional dimension of the connecting portion 112 is larger than the cross-sectional dimension of the gripping portion 111, thereby preventing the operator's hand from touching other parts of the angle grinder when the operator grips the gripping portion 111.

[0034] In one embodiment, if Figure 6 As shown, the radial direction of the connecting portion 112 is provided with a second through hole 1122 for the protruding member 13 to pass through. The second through holes 1122 are directly formed during the injection molding of the handle body 11, and the number of the second through holes 1122 is consistent with the number of the protruding members 13. After the protruding member 13 protrudes from the handle body 11 from the connecting portion 112, the operator can avoid touching the protruding member 13 when using the angle grinder, thereby preventing the protruding member 13 from affecting the normal use of the angle grinder.

[0035] The auxiliary handle 1 in one embodiment of the utility model further includes a protective cover 15, which is combined with the protruding piece 13 protruding from the handle body 11 to protect the protruding piece 13. In order to facilitate the removal and installation of the protective cover 15, the protective cover 15 is interference-fitted with the protruding piece 13. Specifically, the size of the internal cavity of the protective cover 15 can be set to be appropriately smaller than the cross-sectional size of the protruding piece 13, or one or more jacks combined with the protruding piece 13 can be set inside the protective cover 15, and the profile of the jack is basically consistent with the protruding piece 13 but the size is slightly smaller than the jack of the protruding piece 13.

[0036] In one embodiment, in the radial direction of the handle body 11, the projection of the end of the protective cover 15 away from the handle body 11 is a rectangle, that is, the end of the protective cover 15 away from the handle body 11 is a square structure. After the handle body 11 with the protective cover 15 installed is placed on the operating table or the ground, the square structure contacts the operating table or the ground, which can prevent the handle body 11 from rolling along the operating table or the ground.

[0037] Another embodiment of the utility model provides an angle grinder, comprising a main handle 2, a mounting portion 3, a slice 4, a pressing plate 5 and the auxiliary handle 1. The mounting portion 3 is connected to the main handle 2, and the slice 4 is mounted on the mounting portion 3. The pressing plate 5 is detachably mounted on the mounting portion 3 and presses the slice 4 from both sides of the slice 4. The pressing plate 5 is provided with a coupling hole 51 for inserting the protruding member 13. The auxiliary handle 1 is detachably connected to the mounting portion 3 or the main handle 2 through a connecting member 12.

[0038] In the above embodiment, when the angle grinder works normally, the auxiliary handle 1 is mounted on the main handle 2 or the mounting portion 3, and the operator holds the main handle 2 and the auxiliary handle 1 with both hands. When the tightness of the pressing plate 5 needs to be adjusted, the auxiliary handle 1 is removed, the protruding piece 13 is inserted into the corresponding coupling hole 51, and then the auxiliary handle 1 is rotated to drive the pressing plate 5 to rotate to adjust the tightness of the pressing plate 5.
