The unlocking portion 23 rotates about a third axis 103 when receiving a triggering force to drive the limiting portion 24 to release the holding force on the accessory 3. In this embodiment, the third axis 103 is parallel to but does not coincide with the first axis 101. In some embodiments, the third axis 103 intersects the first axis 101.

[0063] Since the limiting portion 24 can only be unlocked by rotating the unlocking portion 23. Therefore, unless the user rotates the unlocking portion 23, the unlocking portion 23 is not easily accidentally touched and unlocked, which plays a role in preventing the accessory 3 from being separated from the hand-held power tool due to the user's accidental touch.

[0064] As Figures 2-4 shown, in some embodiments, the accessory socket 2 includes at least two receiving portions 22 for receiving at least two accessories 3. By providing a plurality of receiving portions 22 on the accessory socket 2, different accessories 3 can be configured according to the needs of the user. When the accessory 3 is a belt buckle, one end of the belt buckle is inserted into one receiving portion 22, and then the belt buckle is passed through the waistband on the staff member. The other end of the belt buckle is buckled into another receiving portion 22, so as to hang the hand-held power tool on the waist of the staff member, freeing the hands of the staff member. By providing at least two receiving portions 22. Different accessories 3 can also be configured according to needs. Insert a buckle into one receiving portion 22, and insert a screwdriver bit or a container for storing screws into another receiving portion 22. While the hand-held power tool can be suspended using the buckle, it is also convenient to carry the screwdriver bit or screws, thus meeting the working needs well.

[0065] As Figures 2-4 shown, in some embodiments, the number of unlocking portions 23 is one. The unlocking portion 23 includes a plurality of positions corresponding to unlocking each accessory 3. The unlocking portion 23 can be operated to switch between a plurality of positions to release the holding force on the corresponding accessory 3. In this embodiment, the accessory socket 2 includes at least two receiving portions 22. When configuring one unlocking portion 23, by setting that the unlocking portion 23 has at least two positions, when the unlocking portion 23 is rotated to the corresponding position, the limiting portion 24 at the corresponding receiving portion 22 can be unlocked from locking the accessory 3. Moreover, only one unlocking portion 23 is arranged, which reduces the number of parts used while meeting the unlocking requirements, and the structure of the accessory socket 2 is simple.

[0066] In some embodiments, the unlocking portion 23 is swingably disposed about the third axis 103. By swinging through different angles, the unlocking portion 23 corresponds to different unlocking positions and can release the holding force on the corresponding accessory 3.

[0067] As Figure 1 shown, in some embodiments, the housing 1 includes a first housing 11 extending substantially along the first axis 101 and a first cover portion 12. Among them, the first cover portion 12 is formed or connected to one end of the first housing 11 away from the output portion 20, and the first cover portion 12 extends in a direction intersecting the first axis 101. The first cover portion 12 is formed or connected to one end of the first housing 11 away from the output portion 20. In this embodiment, the first cover portion 12 is the rear cover of the housing 1. An opening is provided at the rear of the accommodation space formed after the left housing and the right housing are assembled, and the first cover portion 12 is connected to the first housing 11 and covers the rear opening. In another embodiment, the first cover portion 12 is formed on the left housing and the right housing, that is to say, the rear wall portion of the left housing and the rear wall portion of the right housing form the first cover portion 12.

[0068] As Figures 3-4 shown, in some embodiments, the unlocking portion 23 is rotatably connected to the first cover portion 12 via the third axis 103. When unlocking the accessory 3 using the unlocking portion 23, it is only necessary to rotate the unlocking portion 23 to the unlocking position.

[0069] As Figures 2-4 shown, in some embodiments, the accessory socket 2 further includes a second cover portion 21, and the second cover portion 21 and the first cover portion 12 form an accommodation space. The accommodation space is used to at least partially house the receiving portion 22, the limiting portion 24, and the unlocking portion 23. Through the above arrangement, it is convenient to install the receiving portion 22, the limiting portion 24, and the unlocking portion 23. In the above manner, the accessory socket 2 can be designed as an independent unit, and the accessory socket 2 can be detachably disposed on the handheld power tool. During actual use, different accessory sockets 2 can be configured according to different working scenarios, so as to flexibly meet the needs of various working scenarios. Moreover, by using the first cover portion 12 and the second cover portion 21 to form a relatively enclosed accommodation space, the limiting portion 24 and the unlocking portion 23 can be protected.

[0070] As Figures 2-4As shown, in some embodiments, the unlocking portion 23 includes an operating member 231, and the operating member 231 forms or is connected to the limiting portion 24; the operating member 231 is movably connected to the second cover portion 21 and at least partially protrudes from the second cover portion 21. In some embodiments, the limiting portion 24 includes a clamping component in an "X" shape, and the clamping component is formed by rotatably connecting two clamping members 241 in a "V" shape through a rotating shaft. On the side of the two clamping members 241 close to the receiving portion 22, a first clamping groove 245 for holding the accessory 3 or a similar clamping groove structure is formed relatively. The accessory 3 is held in the first clamping groove 245 of the clamping member 241.

[0071] As Figures 3-5 As shown, in some embodiments, the unlocking portion 23 is driven by the limiting portion 24 to reset. The unlocking portion 23 includes a reset member 232. After the operating member 231 is released, the reset member 232 can drive the operating member 231 of the unlocking portion 23 to reset, and at the same time provide a holding force for the limiting portion 24 to hold the accessory 3. In some embodiments, the reset member 232 is a compression spring, and the compression spring is located in the second clamping groove 246 formed by the two clamping members 241. In this embodiment, the second clamping groove 246 for accommodating the reset member 232 is located on the side away from the receiving portion 22, and the first clamping groove 245 for holding the accessory 3 is located on the side close to the receiving portion 22. The two ends of the compression spring abut against two sides of the two clamping members 241 on the same side, so that the two sides on the side close to the receiving portion 22 have a tendency to approach each other, thereby clamping the accessory 3 in the first clamping groove 245 to maintain the holding force of the accessory 3. When unlocking the accessory 3, rotate the operating member 231, and the operating member 231 pushes one of the clamping members 241 to rotate relative to the other clamping member 241, thereby squeezing the compression spring, and the first clamping groove 245 for clamping the accessory 3 expands, so as to take out the accessory 3. After taking out the accessory 3, release the operating member 231, and under the action of the elastic restoring force of the compression spring, the operating member 231 is pushed to reset, and at the same time the clamping member 241 is driven to reset, and the first clamping groove 245 returns to the clamping state. In other embodiments, a torsion spring can also be used as the reset member 232. The torsion spring is arranged on the operating member 231, and one end of the torsion spring is connected to the operating member 231, and the other end of the torsion spring is connected to the first cover portion 12 or the second cover portion 21. During the process of rotating the operating member 231, the torsion spring stores energy; after releasing the operating member 231, the operating member 231 automatically resets under the action of the torsion spring.

[0072] As Figure 3As shown, in some embodiments, the unlocking position of the unlocking portion 23 corresponds to the position of the accessory 3. During the unlocking operation, the user can rotate the unlocking portion 23 in the corresponding direction according to the accessory 3 to be unlocked. For example, to unlock the accessory 3 on the left side, only need to turn the operating member 231 of the unlocking portion 23 to the left; to unlock the accessory 3 on the right side, only need to turn the operating member 231 of the unlocking portion 23 to the right. The position where the operating member 231 returns to is the locking position. When the operating member 231 is in the locking position, the accessory 3 is respectively restricted in the accessory socket 2 by the limiting portion 24. In this embodiment, the locking position of the operating member 231 is the initial position, that is to say, the operating member 231 always remains in the locking position without external force driving. Through the above settings, it is convenient for the user to operate.

[0073] As Figure 2 shown, in some embodiments, anti-slip patterns 2311 are provided on the surface of the operating member 231. During the rotation of the operating member 231 by the user, the friction between the operating member 231 and the user's finger can be increased, thereby facilitating the control of the rotation of the operating member 231.

[0074] In some embodiments, the accessory socket 2 is detachably installed on the upper side, left side, and right side of the housing 1 of the hand-held power tool. In some embodiments, the accessory socket 2 can be detachably installed at the power connection portion 40 or the holding portion 10, and can be arranged according to the application scenario of the hand-held power tool and the usage habits of the staff.

[0075] The process of disassembling and assembling the accessory 3 on the hand-held power tool is as follows:

[0076] Installing the accessory 3: First, insert one side of the buckle member 32 of the accessory 3 into the receiving portion 22 and contact the limiting portion 24. Then rotate and press the buckle member 32 so that the other side of the buckle member 32 is also inserted into the receiving portion 22. One of the engaging members 241 rotates, making the first slot 245 larger. Until the buckle member 32 is in place, the engaging member 241 returns under the action of the restoring member 232, thereby engaging with the buckle member 32 to hold the accessory 3 in the receiving portion 22 and complete the locking.

[0077] Removing the accessory 3: First, rotate the operating member 231 of the unlocking portion 23 in the direction of the accessory 3 to be removed. The operating member 231 abuts against and pushes one of the engaging members 241 of the limiting portion 24 to rotate, making the first slot 245 for engaging the accessory 3 larger. Using the side of the buckle member 32 of the accessory 3 away from the operating member 231 as a fulcrum, then rotate the buckle member 32, and the accessory 3 can be taken out.

[0078] The present application also provides a hand-held power tool, including a motor, an output portion 20, an outer case, and an accessory socket 2.

[0079] The motor includes a driving shaft rotating around a driving axis, an output part 20 is driven by the motor to output power, and a housing 1 accommodates the motor. The accessory socket 2 is detachably connected to an accessory 3 of a handheld power tool, and the accessory socket 2 includes a receiving part 22, a limiting part 24, and an unlocking part 23. Among them, the receiving part 22 receives at least two accessories 3; the limiting part 24 holds the accessory 3 in the receiving part 22; the unlocking part 23 is connected to the limiting part 24, the number of the unlocking part 23 is one, and the unlocking part 23 is operated to move between multiple positions; when the unlocking part 23 moves to an unlocking position among multiple positions, the unlocking part 23 drives the limiting part 24 to release the holding force on the accessory 3. When the accessory 3 needs to be unlocked and taken out, the accessory 3 can be taken out by simply moving the unlocking part 23 to the corresponding unlocking position.

[0080] like Figures 1-7 As shown, the present application provides a handheld power tool. The handheld power tool comprises a motor, an output part 20, a housing 1 and an accessory socket 2. The motor comprises a drive shaft rotating around a drive axis; the output part 20 is driven by the motor to output power; and the housing 1 accommodates the motor.

[0081] The accessory socket 2 is used for detachably connecting an accessory 3 of a handheld power tool, and the accessory socket 2 includes a receiving portion 22 and a limiting portion 24. The receiving portion 22 is provided with a receiving groove that cooperates with the accessory 3 and is used to receive at least one accessory 3; the limiting portion 24 applies a retaining force to the accessory 3 to retain the accessory 3 in the receiving portion 22; the limiting portion 24 includes a limiting surface 244, and the accessory 3 includes a stop surface 323. When the accessory 3 is retained in the receiving groove, the limiting surface 244 contacts the stop surface 323 to limit the displacement of the accessory 3 along the first direction, and the angle α between the length extension direction of the stop surface 323 and the second direction is less than or equal to 30°, the second direction is perpendicular to the first direction, and the second direction and the length extension direction of the stop surface 323 are in the same plane.

[0082] like Figures 3-7 As shown, the limiting surface 244 of the limiting portion 24 contacts the stop surface 323 to limit the displacement of the accessory 3 along the first direction, thereby reducing the gap between the accessory 3 and the limiting portion 24, reducing the shaking of the accessory 3, and facilitating the cooperation between the accessory 3 and the limiting portion 24 to lock the accessory 3 on the handheld power tool. Since the angle α between the length extension direction of the stop surface 323 and the second direction perpendicular to the first direction is less than or equal to 30°, a self-locking angle is formed at the stop surface 323, which can prevent the limiting portion 24 from being opened and unlocked after the accessory 3 is subjected to force, thereby preventing the accessory 3 from being separated from the handheld power tool.

[0083] In some embodiments, the angle α between the length extension direction of the stop surface 323 and the second direction is less than or equal to 25°. In some embodiments, the angle α between the length extension direction of the stop surface 323 and the second direction is less than or equal to 20°. In some embodiments, the angle α between the length extension direction of the stop surface 323 and the second direction is less than or equal to 18°. As Figure 3 and Figure 6 shown, in some embodiments, the accessory 3 includes a first surface 31, and the limiting portion 24 includes a second surface 242. By driving the accessory 3 to move in a preset direction, the first surface 31 of the accessory 3 can push the second surface 242 of the limiting portion 24, so that the limiting portion 24 moves in the direction of releasing the holding force on the accessory 3. The first surface 31 of the accessory 3 is connected to the stop surface 323, so that a triangular protrusion is formed on the side surface of the buckle 32 of the accessory 3. Both the first surface 31 and the second surface 242 are inclined surfaces. During the process of inserting the buckle 32 of the accessory 3 into the receiving portion 22, relative sliding is generated between the first surface 31 and the second surface 242, and the first surface 31 presses the second surface 242, so that the limiting portion 24 moves in the direction of releasing the holding force on the accessory 3. After the accessory 3 is installed in place, the first surface 31 is separated from the second surface 242, the limiting portion 24 resets, and the limiting surface 244 of the limiting portion 24 contacts the stop surface 323 of the accessory 3, thereby restricting the displacement of the accessory 3 along the first direction, thereby clamping and fixing the accessory 3, and realizing the installation and fixation of the accessory 3 on the accessory socket 2. In some embodiments, the first surface 31 or the second surface 242 can also be set separately, and no further limitation is made here.

[0084] As Figure 3 and Figure 7 shown, in some embodiments, a slot 322 is formed on the side surface of the accessory 3, and the slot 322 is used to accommodate the limiting surface 244 of the limiting portion 24. One side wall surface of the slot 322 is the stop surface 323. By providing the slot 322, it can be ensured that the limiting portion 24 cooperates with the slot 322, thereby locking the accessory 3. When the limiting portion 24 is not unlocked, even if a large pulling force is used, the accessory 3 cannot be pulled out.

[0085] As Figure 3 and Figure 7 shown, in some embodiments, the limiting portion 24 extends into or is embedded in the accessory 3 to realize the holding of the accessory 3. The accessory 3 has a slot 322, and the limiting portion 24 can be stably fixed to the accessory 3 by extending into or being embedded in the slot 322 of the accessory 3. Through the above method, it is convenient for the limiting portion 24 to fix the accessory 3, and the structure is simple.

[0086] As Figures 2-5As shown, in some embodiments, the hand-held power tool further includes an unlocking portion 23. The unlocking portion 23 is connected to the limiting portion 24. The unlocking portion 23 rotates about the third axis 103 when receiving a triggering force, so as to drive the limiting portion 24 to release the holding force on the accessory 3. After the accessory 3 is installed in place, the limiting portion 24 stably cooperates with the accessory 3, thereby locking the accessory 3. When it is necessary to remove or replace the accessory 3, rotate the unlocking portion 23, so that the unlocking portion 23 pushes the limiting portion 24 to move, thereby releasing the holding force on the accessory 3, and then the accessory 3 can be taken out. In other embodiments, the unlocking portion 23 can also drive the limiting portion 24 to release the holding force on the accessory 3 by sliding, and no further limitation is made here.

[0087] As Figures 2-4 shown, in some embodiments, the number of the unlocking portions 23 is one. The unlocking portion 23 includes a plurality of positions corresponding to the unlocking of each accessory 3. The unlocking portion 23 can be operated to switch between the plurality of positions to release the holding force on the corresponding accessory 3. When the accessory socket 2 includes at least two receiving portions 22, when configuring one unlocking portion 23, by setting that the unlocking portion 23 has a plurality of positions, when the unlocking portion 23 is rotated to the corresponding position, the locking of the limiting portion 24 at the corresponding receiving portion 22 on the accessory 3 can be unlocked. Moreover, only one unlocking portion 23 is arranged, which reduces the number of parts used while meeting the unlocking requirements, and the structure of the accessory socket 2 is simple.

[0088] As Figure 3 and Figure 4 shown, in some embodiments, the unlocking portion 23 is driven by the limiting portion 24 to reset. When unlocking, rotate the unlocking portion 23 to push the limiting portion 24 to move, thereby unlocking the accessory 3. During this process, the limiting portion 24 is stressed and in an energy storage state. After the accessory 3 is taken out, the unlocking portion 23 is no longer manipulated, and under the action of the limiting portion 24, the unlocking portion 23 automatically resets, and at the same time, the limiting portion 24 returns to the state of applying the holding force to the accessory 3.

[0089] In some embodiments, the unlocking position of the unlocking portion 23 corresponds to the position of the accessory 3. During the unlocking operation, the user rotates the unlocking portion 23 in the corresponding direction according to the accessory 3 to be unlocked. For example, when it is necessary to unlock the accessory 3 on the left, only need to rotate the operating member 231 of the unlocking portion 23 to the left; when it is necessary to unlock the accessory 3 on the right, only need to rotate the operating member 231 of the unlocking portion 23 to the right. Through the above settings, it is convenient for the user to operate.

[0090] As Figure 2As shown, in some embodiments, the accessory socket 2 includes at least two receiving portions 22 for receiving at least two accessories 3. By providing a plurality of receiving portions 22 on the accessory socket 2, different accessories 3 can be configured according to the needs of the user. When the accessory 3 is a belt buckle, one end of the belt buckle is inserted into one receiving portion 22, then the belt buckle is passed through the waist belt of the worker, and the other end of the belt buckle is buckled into another receiving portion 22, so as to hang the hand-held power tool on the waist of the worker, freeing the hands of the worker. By providing at least two receiving portions 22, different accessories 3 can also be configured according to needs. A buckle is inserted into one receiving portion 22, and a screwdriver bit or a container for storing screws is inserted into another receiving portion 22. While the hand-held power tool can be suspended by the buckle, it is also convenient to carry the screwdriver bit or screws, thus well meeting the needs of work.

[0091] As Figure 6 As shown, in some embodiments, the hand-held power tool further includes a limit pad 26 for filling the gap between the accessory 3 and the receiving portion 22 or the limiting portion 24. In some embodiments, the limit pad 26 is made of an elastic or soft material. In this embodiment, the limit pad 26 is made of rubber. By providing the limit pad 26, it can be ensured that the accessory 3 will not shake relative to the receiving portion 22 after installation, ensuring the stability of the accessory 3 after installation.
