[0028] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0029] In one embodiment, please refer to Figures 1-4 An integrated auxiliary handle is provided, comprising: an auxiliary handle part 1, a connecting part 2, and a wrench 3. The auxiliary handle part 1 is used to assist in gripping the angle grinder and is also used to operate the wrench to remove the cutting disc pressure plate 42 of the angle grinder. The cutting disc pressure plate 42 includes upper and lower pressure plates that clamp the cutting disc 41 in the middle.

[0030] Specifically, the connecting part 2 is connected to the front end of the auxiliary handle part 1 (i.e., the right end in the figure). When it is necessary to remove the cutting disc pressure plate 42, i.e., when the wrench is in use, the connecting part 2 is used to detachably fix the wrench 3 to the auxiliary handle part 1, such as... Figure 1 As shown, the wrench 3 is operated by holding the secondary handle 1 to disassemble the cutting disc pressure plate 42. When not in use, the wrench is detachably fixed inside the secondary handle 1; specifically, please refer to... Figure 3 The auxiliary handle 1 is provided with a receiving cavity 11 for accommodating the wrench 3. The opening of the receiving cavity 11 is located at the rear end of the auxiliary handle (i.e., the left end in the figure). A fixing unit is provided at the bottom of the receiving cavity for detachably fixing the wrench 3. When not in use, the wrench 3 is snapped into the fixing unit, i.e., hidden inside the auxiliary handle 1, to prevent loss. When the angle grinder needs to be operated, the connecting part 2 is used to detachably fix the auxiliary handle 1 to the angle grinder body 4, such as... Figure 2 As shown, the angle grinder is held with the assistance of the auxiliary handle 1.

[0031] In this embodiment, the fixing unit is taken as buckle 12 as an example, such as Figure 3 , Figure 4 As shown, the clip 12 is used to detachably engage the wrench 3.

[0032] In another embodiment, the fixing unit can also be a magnetic suction element 14, such as... Figure 5 As shown, the magnetic component 14 is used to detachably attach the wrench 3. The corresponding part of the wrench can be directly set as a magnetically attachable metal component, or a magnetically attachable metal component can be set at a corresponding position on the wrench 3.

[0033] In one embodiment, the fixing unit and the bottom of the receiving cavity can be connected by screws. Preferably, the screws can be self-tapping screws 13, such as... Figure 4 , Figure 5 As shown, the buckle 12 or magnetic component 14 is fixed to the bottom of the receiving cavity 11 by the self-tapping screw 13.

[0034] In one embodiment, an outwardly projecting portion 15 is provided at the front end near the auxiliary handle, such as... Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown. The protrusion 15 provides better protection for the hand, preventing it from slipping inward and coming into contact with the machine or the cutting disc.

[0035] In one embodiment, the connection between the connecting part and the angle grinder body can be achieved through a threaded connection. Specifically, the outer wall of the connecting part 2 is provided with an external thread 21, such as... Figure 4 , Figure 5 As shown; the angle grinder body is provided with threaded holes that match the threads of the connecting parts.

[0036] In one embodiment, the wrench includes a wrench head 31, a connecting plate 32, and a wrench body 33 arranged sequentially, such as... Figure 4As shown. The wrench head 31 is used to connect with the connecting part; in this embodiment, the wrench is detachably engaged by a snap-fit ​​mechanism, which is also achieved by engaging the wrench head. Furthermore, the wrench head 31 is perpendicular to the connecting plate 32, and the wrench body 33 is obtusely angled to the connecting plate 32, with the wrench head 31 and wrench body 33 located on the same side of the connecting plate 32. The lower end face of the wrench body 33 is provided with at least one force-applying protrusion 34; in this embodiment, two are used as an example, where the lower end face of the wrench body 33 refers to the end face of the wrench body 33 furthest from the wrench head 31. When disassembling the cutting disc, the force-applying protrusion 34 can be inserted into the limiting hole of the cutting disc pressure plate to apply rotational force. With the design of the wrench structure in this embodiment, the wrench occupies little space when stored in the receiving cavity, making it easy to store. In addition, after the wrench head is connected to the connecting part, the auxiliary handle and the wrench body are also distributed at an obtuse angle. At this angle, when the hand holds the auxiliary handle to operate, it can reasonably avoid the angle grinder guard, and the operation is convenient and labor-saving.

[0037] In practice, the connection between the wrench head 31 and the connecting part 2 can be achieved by means of threads. The wrench head 31 is provided with a hole 311, and the hole 311 is provided with internal threads. When connection is required, the front end of the connecting part 2 is inserted into the hole 311, and then the external thread of the front end of the connecting part 2 is screwed into the internal thread of the wrench hole 311 to complete the fixing of the wrench.

[0038] In a preferred embodiment, a nut 312 can also be welded onto the wrench head. This nut matches the external thread at the front end of the connecting part, thus making the connection between the wrench head and the connecting part 2 more stable. Figure 1 As shown.

[0039] In different embodiments, the number of force-applying protrusions 34 is not necessarily two. For example, when there are three limiting holes on the cutting disc pressure plate, the number of force-applying protrusions can also be three, and so on. The number of force-applying protrusions is not limited here.

[0040] In one embodiment, the latch includes: a connector 121 and two spring clips 122, such as... Figure 4 As shown. Connector 121 is connected to the bottom of receiving cavity 11. Two spring pieces 122 are respectively disposed at both ends of connector 121, and each is curved towards the side away from the bottom of receiving cavity 11; the middle part of one spring piece 122 forms a recess 1221 towards the other spring piece 122. When the wrench is idle, with the wrench head facing the bottom of the receiving cavity, pressing the wrench downwards causes the two spring pieces to deform outwards, and the wrench head passes downwards through the recess 1221. The opposite sides of the wrench head are respectively engaged with the lower parts of the two spring pieces. The lower part of the spring piece 122 refers to the part of the spring piece 122 located between connector 121 and recess 1221. When the wrench is needed, pulling the wrench outwards causes the two spring pieces to deform outwards, and the wrench head passes outwards through the recess 1221, allowing the wrench to be removed from the latch.

[0041] In one embodiment, the wrench body 33 is also provided with an avoidance hole 331, such as... Figure 4 As shown, this is used to avoid the output shaft head of an angle grinder. The illustration uses two force-applying protrusions 34 as an example. These two protrusions correspond to two limiting holes on the cutting disc pressure plate, located at both ends of the threaded hole in the pressure plate. The avoidance hole 331 is also located between the two force-applying protrusions 34. Compared to a situation where the wrench body is made narrower to avoid the output shaft head, placing the wrench body on the side of the output shaft head, this embodiment allows for a wider wrench body and a more stable structure by providing the avoidance hole. Furthermore, when using the wrench to remove the cutting disc, the output shaft head passes through the avoidance hole. During operation, in addition to the restriction between the force-applying protrusions on the wrench and the limiting holes on the cutting disc pressure plate, the output shaft also restricts the wrench, making the wrench operation more stable.

[0042] In one embodiment, the outer surface of the auxiliary handle 1 is covered with an adhesive layer 16, such as... Figure 3 As shown, it has a better feel and greater friction, making it easier to operate.

[0043] In one embodiment, please refer to Figure 2 Furthermore, an angle grinder is provided, comprising: an angle grinder body 4 and an integrated auxiliary handle. The integrated auxiliary handle is the integrated auxiliary handle described in any of the above embodiments, comprising: an auxiliary handle portion 1, a connecting portion 2, and a wrench 3. The integrated auxiliary handle is detachably fixed to the angle grinder body 4.

[0044] When the angle grinder needs to be operated, the integrated auxiliary handle can be fixed to the angle grinder body for assisting in gripping the grinder. When the cutting disc needs to be removed, the integrated auxiliary handle is removed from the angle grinder body, the wrench is removed from the fixing unit, and then the wrench is fixed to the connecting part. The wrench is operated by holding the auxiliary handle to remove the cutting disc pressure plate.

[0045] In the description of this specification, the references to terms such as "an embodiment," "an example," "a specific implementation process," and "an example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
