[0014] The limiting portion applies a retaining force to the accessory to retain the accessory in the receiving portion; the limiting portion includes a limiting surface, and the accessory includes a stop surface. When the accessory is retained in the receiving groove, the limiting surface contacts the stop surface to limit the displacement of the accessory along the first direction. The angle between the length extension direction of the stop surface 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 are in the same plane.

[0015] In some embodiments, the accessory includes a first surface, and the limiting portion includes a second surface. By driving the accessory to move in a preset direction, the first surface of the accessory can push the second surface of the limiting portion to cause the limiting portion to move in a direction that releases the holding force on the accessory.

[0016] In some embodiments, a slot is formed on the side of the attachment, and the slot is used to accommodate the limiting surface of the limiting portion.

[0017] In some embodiments, the limiting portion extends into or embeds the accessory to achieve retention of the accessory.

[0018] In some embodiments, an unlocking portion is further included, the unlocking portion is connected to the limiting portion, and the unlocking portion rotates around the third axis upon receiving a trigger force to drive the limiting portion to release the holding force on the accessory.

[0019] In some embodiments, the number of the unlocking part is one, and the unlocking part includes a plurality of positions corresponding to each of the accessories for unlocking, and the unlocking part can be operated to switch between the plurality of positions to release the holding force of the corresponding accessories.

[0020] In some embodiments, the unlocking portion is driven by the limiting portion to reset.

[0021] In some embodiments, the unlocking position of the unlocking portion corresponds to the position of the accessory.

[0022] In some embodiments, the accessory socket includes at least two receiving portions to receive at least two of the accessories.

[0023] In some embodiments, a limiting pad is further included, and the limiting pad is used to fill the gap between the accessory and the receiving portion or the limiting portion.

[0024] The benefits of this application are:

[0025] The present application provides a handheld power tool, including an accessory socket, which includes a receiving portion and a limiting portion. The receiving portion's receiving slot can receive the accessory, and the limiting portion can apply a retaining force to retain the accessory in the receiving portion. When the accessory is retained in the receiving slot, the limiting surface of the limiting portion contacts the stop surface to limit the displacement of the accessory along a first direction, thereby reducing the gap between the accessory and the limiting portion and reducing the shaking of the accessory. Since the angle between the length extension direction of the stop surface and the second direction perpendicular to the first direction is less than or equal to 30°, a self-locking angle is formed, which can prevent the limiting portion from being opened and unlocked after the accessory is subjected to force, thereby preventing the accessory from separating from the handheld power tool.

[0044] In daily production and life, hand-held power tools play a very important role. Hand-held power tools include, but are not limited to, electric hand drills, percussion drills, impact wrenches, impact screwdrivers, angle grinders, etc. Electric hand drills and percussion drills can be configured with drill bits of different diameters to drill holes in objects. Impact wrenches are used to tighten bolts and nuts. Impact screwdrivers are usually used to loosen or tighten screws, etc. Angle grinders can grind and cut objects. By using hand-held power tools, work efficiency can be improved and labor intensity can be reduced.

[0045] As Figures 1-7 shown, in this embodiment, the hand-held power tool takes a gun-shaped tool as an example, such as the screwdriver 100. When in use, by configuring different execution components, such as drill bits, grinding discs, saw blades, sockets, etc., the hand-held power tool performs different tasks.

[0046] As Figure 1 shown, the screwdriver 100 includes a motor, an output part 20 and a housing 1. In this embodiment, the screwdriver 100 further includes a power supply, and the power supply is used to supply electrical energy to the screwdriver 100. In this embodiment, the power supply is a DC power supply. Optionally, the DC power supply is a battery pack 30, and the battery pack 30 cooperates with a corresponding power circuit to supply power to the screwdriver 100. Those skilled in the art should understand that the DC power supply is not limited to the scenario of using the battery pack 30, and it can be an internal rechargeable battery or a standard battery. In other alternative embodiments, the screwdriver 100 can also be powered by mains electricity or an AC power supply, in cooperation with corresponding rectification, filtering and voltage regulation circuits, to supply power to the corresponding components inside the machine. For the convenience of reference in subsequent descriptions, the battery pack 30 will be used to replace the DC power supply, but it should not be regarded as a limitation of the present invention.

[0047] In some embodiments, the battery pack 30 can be a lithium battery, a solid-state battery pack or a soft-pack battery pack. The nominal voltage of the battery pack 30 is greater than or equal to 10V and less than or equal to 80V. Optionally, the nominal voltage of the battery pack 30 is greater than or equal to 10V and less than or equal to 48V.

[0048] As Figure 1As shown, in this embodiment, the motor includes a drive shaft that rotates about a drive axis; an output portion 20 is driven by the motor to output power; a housing 1 is used to house the motor; the housing 1 includes a first housing 11 that extends substantially along a first axis 101 and a power connection portion 40, and the first housing 11 houses at least the motor, and the power connection portion 40 receives at least part of the power supply. The first housing 11 includes a left housing and a right housing that are divided left and right. In some embodiments, the first housing 11 includes a left housing and a right housing that are divided left and right, and the left housing and the right housing are respectively configured with rear portions, that is to say, after the left housing and the right housing are assembled, the rear portion is a closed structure.

[0049] In order to facilitate carrying the hand-held power tool with one's own body, or to facilitate hanging it on the body or on a fixed place when the hand-held power tool is not used temporarily, the hand-held power tool is provided with accessories 3 such as belt buckles, buckles, and belt clips. Moreover, in order to enable the user to conveniently replace the execution components when using multiple execution components, the hand-held power tool is provided with a storage accessory 3 to hold multiple execution components on the hand-held power tool at the same time.

[0050] As Figures 2-4 shown, the hand-held power tool further includes an accessory socket 2 for detachably connecting the accessory 3 of the hand-held power tool. The accessory socket 2 includes a receiving portion 22, a limiting portion 24, and an unlocking portion 23. Among them, the receiving portion 22 is provided with a receiving groove that cooperates with the accessory 3 for receiving at least one accessory 3. The limiting portion 24 applies a holding force to the accessory 3 to hold the accessory 3 in the receiving portion 22. The unlocking portion 23 is connected to the limiting portion 24, and 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.

[0051] 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.

[0052] As Figures 2-4As 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 waistband on the staff member, 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 staff member and free 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 a screwdriver bit or a container for storing screws into another receiving portion 22. While the hand-held power tool can be suspended by using the buckle, it is also convenient to carry the screwdriver bit or screws, so as to meet the working needs well.

[0053] 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 the unlocking of each accessory 3. The unlocking portion 23 can be operated to switch between a plurality of positions to release the holding force of 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 locking of the limiting portion 24 at the corresponding receiving portion 22 to 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.

[0054] In some embodiments, the unlocking portion 23 is swingably arranged around the third axis 103. By swinging the unlocking portion 23 at different angles, corresponding unlocking positions are provided, and the holding force of the corresponding accessory 3 can be released.

[0055] As Figure 1 shown, in some embodiments, the housing 1 includes a first housing 11 and a first cover portion 12 that generally extend along the first axis 101. 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.

[0056] As Figures 3-4As 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.

[0057] As Figures 2-4 As 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 arranged 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.

[0058] As Figures 2-4 As shown, in some embodiments, the unlocking portion 23 includes an operating member 231, and the operating member 231 is formed or 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 assembly in an "X" shape, and the clamping assembly is formed by rotatably connecting two clamping members 241 in a "V" shape via 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.

[0059] As Figures 3-5As 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 to the limiting portion 24 to hold the accessory 3. In some embodiments, the reset member 232 is a compression spring. The compression spring is located in the second card slot 246 formed by the two engaging members 241. In this embodiment, the second card slot 246 for accommodating the reset member 232 is located on the side away from the receiving portion 22, and the first card slot 245 for holding the accessory 3 is located on the side close to the receiving portion 22. Both ends of the compression spring abut against two sides of the two engaging members 241 on the same side, so that the two sides on the side close to the receiving portion 22 tend to approach each other, thereby clamping the accessory 3 in the first card slot 245 to maintain the holding force of the accessory 3. When unlocking the accessory 3, rotate the operating member 231. The operating member 231 pushes one of the engaging members 241 to rotate relative to the other engaging member 241, thereby squeezing the compression spring. The first card slot 245 for clamping the accessory 3 expands, and the accessory 3 can be taken out. After taking out the accessory 3, release the operating member 231. 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 engaging member 241 is driven to reset, and the first card slot 245 returns to the clamped 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 the operating member 231 is released, the operating member 231 automatically resets under the action of the torsion spring.

[0060] As Figure 3 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, only need to rotate the operating member 231 of the unlocking portion 23 to the left; to unlock the accessory 3 on the right, only need to rotate the operating member 231 of the unlocking portion 23 to the right. The position when the operating member 231 resets 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.

[0061] As Figure 2As shown, in some embodiments, anti-slip patterns 2311 are provided on the surface of the operating member 231. During the process of the user rotating the operating member 231, 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.

[0062] In some embodiments, the accessory socket 2 is detachably mounted on the upper side, left side, or right side of the housing 1 of the hand-held power tool. In some embodiments, the accessory socket 2 can be detachably mounted at the power connection portion 40 or the gripping portion 10, and can be arranged according to the application scenario of the hand-held power tool and the usage habits of the staff.

[0063] The process of disassembling and assembling the accessory 3 on the hand-held power tool is as follows:

[0064] 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. After the buckle member 32 is in place, the engaging member 241 is reset under the action of the reset member 232, so as to engage with the buckle member 32 and hold the accessory 3 in the receiving portion 22 to complete the locking.

[0065] 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.

[0066] This application also provides a hand-held power tool, including a motor, an output portion 20, an outer case, and an accessory socket 2.

[0067] The motor includes a drive shaft that rotates about a drive axis. The output portion 20 is driven by the motor to output power. The housing 1 houses the motor. The accessory socket 2 is detachably connected to the accessory 3 of the hand-held power tool. The accessory socket 2 includes a receiving portion 22, a limiting portion 24, and an unlocking portion 23. Among them, the receiving portion 22 receives at least two accessories 3; the limiting portion 24 holds the accessory 3 in the receiving portion 22; the unlocking portion 23 is connected to the limiting portion 24. The number of unlocking portions 23 is one, and the unlocking portion 23 is operated to move between multiple positions; when the unlocking portion 23 moves to the unlocking position among the multiple positions, the unlocking portion 23 drives the limiting portion 24 to release the holding force on the accessory 3. When it is necessary to unlock and remove the accessory 3, only need to move the unlocking portion 23 to the corresponding unlocking position, and the accessory 3 can be taken out.

[0068] As Figures 1-7As shown, the present application provides a handheld power tool. The handheld power tool includes a motor, an output part 20, a housing 1, and an accessory socket 2. Among them, the motor includes a drive shaft that rotates around a drive axis; the output part 20 is driven by the motor to output power; the housing 1 houses the motor.

[0069] The accessory socket 2 is used for detachably connecting an accessory 3 of the handheld power tool. The accessory socket 2 includes a receiving part 22 and a limiting part 24. The receiving part 22 is provided with a receiving groove that cooperates with the accessory 3 for receiving at least one accessory 3; the limiting part 24 applies a holding force to the accessory 3 to hold the accessory 3 within the receiving part 22; the limiting part 24 includes a limiting surface 244, and the accessory 3 includes a stop surface 323. When the accessory 3 is held in the receiving groove, the limiting surface 244 contacts the stop surface 323 to limit the displacement of the accessory 3 in a first direction. The included angle α between the length extension direction of the stop surface 323 and a 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.

[0070] As Figures 3-7 shown, since the limiting surface 244 of the limiting part 24 contacts the stop surface 323 to limit the displacement of the accessory 3 in the first direction, the gap between the accessory 3 and the limiting part 24 is reduced, the shaking of the accessory 3 is reduced, and it is also convenient for the accessory 3 and the limiting part 24 to cooperate to lock the accessory 3 on the handheld power tool. Since the included 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 accessory 3 from spreading and unlocking the limiting part 24 after being stressed, and prevent the accessory 3 from separating from the handheld power tool.

[0071] In some embodiments, the included 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 included 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 included 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 6As 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 a direction to release 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 a direction to release 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, and the limiting portion 24 resets. 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 in the first direction, and thus clamping and fixing the accessory 3, realizing the installation and fixing 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 more restrictions are made here.

[0072] As Figure 3 and Figure 7 shown, in some embodiments, a slot 322 is formed on the side surface of the accessory 3. The slot 322 is used to accommodate the limiting surface 244 of the limiting portion 24. The wall surface on one side 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 relatively large pulling force is applied, the accessory 3 cannot be pulled out.

[0073] As Figure 3 and Figure 7 shown, in some embodiments, the limiting portion 24 extends into or is embedded in the accessory 3 to achieve the holding of the accessory 3. The accessory 3 has a slot 322. By extending or embedding the limiting portion 24 into the slot 322 of the accessory 3, the accessory 3 can be stably fixed. Through the above method, it is convenient for the limiting portion 24 to fix the accessory 3, and the structure is simple.

[0074] As Figures 2-5As shown, in some embodiments, the handheld 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.

[0075] 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 arranging one unlocking portion 23 reduces the number of parts used while meeting the unlocking requirements, and the structure of the accessory socket 2 is simple.

[0076] 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 releasing the locking of 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.

[0077] 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.

[0078] 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 staff, 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 staff and free the hands of the staff. 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 using the buckle, it is also convenient to carry the screwdriver bit or the screws, thus well meeting the working needs.

[0079] As Figure 6 As shown, in some embodiments, the hand-held power tool further includes a limiting pad 26, and the limiting pad 26 is used to fill the gap between the accessory 3 and the receiving portion 22 or the limiting portion 24. In some embodiments, the limiting pad 26 is made of an elastic or soft material. In this embodiment, the limiting pad 26 is made of rubber. By providing the limiting pad 26, it can be ensured that the accessory 3 will not shake relative to the receiving portion 22 after installation, and the stability of the accessory 3 after installation is ensured.

[0080] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form. Any technical solutions obtained by using equivalent replacement or equivalent transformation fall within the protection scope of the present application.
