The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0041] Embodiment 1:

[0042] like Figures 1 to 8As shown, the utility model provides a rotatable auxiliary handle, including a handle portion 10 for grasping and a connecting portion 20, the connecting portion 20 is provided with a connecting hole 201 along the Y-axis, the handle portion 10 is rotatably connected to the connecting portion 20 around the X-axis, the X-axis is perpendicular to the Y-axis, and a locking structure for locking the handle portion 10 and the connecting portion 20 is provided between the handle portion 10 and the connecting portion 20, and an unlocking member 40 for releasing the locking structure from locking the handle portion 10 and the connecting portion 20, so that the handle portion 10 has a locked state fixedly connected to the connecting portion 20 and an unlocked state rotatable relative to the connecting portion 20 around the X-axis and the Y-axis.

[0043] With such a design, the handle portion 10 is rotatably connected to the connecting portion 20 around the X-axis, and can be adjusted and rotated according to the needs and preferences of the user, thereby providing a more comfortable and convenient holding experience. Through the design of the locking structure and the unlocking member 40, the user can easily switch the locking state and the unlocking state of the handle portion 10, and realize the rotation adjustment of the handle portion 10 around the X-axis and obtain the lock after adjustment. This design can make the handle portion 10 more flexible and adapt to different usage scenarios and operation requirements. At the same time, the handle portion 10 can also drive the connecting portion 20 to rotate around the Y-axis in the unlocked state, realizing the rotation of the handle portion 10 in multiple directions, further increasing the convenience and flexibility of operation.

[0044] Preferably, the Y axis is the axis of the connecting hole 201, and the X axis is a diameter line parallel to the horizontal plane in the connecting hole 201. When the handle portion 10 of the rotatable auxiliary handle rotates along the Y axis, the X axis is correspondingly changed to a diameter line perpendicular or inclined to the horizontal plane in the connecting hole 201. It should be noted that when the handle portion 10 of the rotatable auxiliary handle rotates along the Y axis, the direction of the X axis is fixed.

[0045] In order to facilitate operation, the handle portion 10 is provided with a gripping hole 101 which is convenient for the user to grip. The unlocking member 40 includes a connecting section 41 connected to the locking structure and a pull ring section 42 which is convenient for the user to grip. The pull ring section 42 is located in the gripping hole 101, and the pull ring section 42 can pull the connecting section 41 to move along the Z axis. With such a design, the gripping hole 101 allows the user to grip the handle portion 10 more easily, providing a more comfortable and stable gripping method, thereby improving the convenience and comfort of operation. Secondly, the pull ring section 42 of the unlocking member 40 is located in the gripping hole 101, and the user can directly unlock through the pull ring section 42 in the gripping hole 101 without additional operation steps, so that the connecting portion 20 can be unlocked more quickly, improving the efficiency of operation. Then, the pull ring section 42 is located in the gripping hole 101, which can also avoid accidental unlocking due to improper unlocking, improve the safety of the device, and also beautify the appearance of the handle portion 10, making the structure of the auxiliary handle more compact.

[0046] Preferably, the Z axis is a diameter line parallel to the vertical plane in the connecting hole 201 .

[0047] Specifically, the locking mechanism includes an elastic reset member 33, two limit members 31 and two lock buttons 32. Each lock button 32 cooperates with a limit member 31. The lock button 32 and the limit member 31 are both mirror-set along the Y axis. The lock button 32 is also provided with a first meshing tooth 322 on the circumferential outer side. The connecting portion 20 is provided with a second meshing tooth 311 that cooperates with the first meshing tooth 322. The two limit members 31 are fixedly connected to the connecting portion 20. The two lock buttons 32 can move along the X axis. The elastic reset member 33 The two ends of the handle 10 are respectively in contact with the two lock buttons 32, and the elastic reset member 33 has a tendency to push the lock button 32 to mesh the first meshing tooth 322 and the second meshing tooth 311 so that the handle 10 has a locking state with the connecting part 20. The lock button 32 is transmission-connected with the unlocking member 40. The lock button 32 is pulled by the unlocking member 40 to overcome the elastic effect of the elastic reset member 33 and move along the X-axis, so that the lock button 32 is disengaged from the limiting member 31 and the handle 10 is in an unlocked state with the connecting part 20. With such a design, the switching between the locking state and the unlocking state of the handle 10 can be achieved through the coordinated action of the limiting member 31, the lock button 32 and the elastic reset member 33. When the unlocking member 40 pushes the locking button 32 to overcome the elastic action of the elastic reset member 33 and move along the X-axis to disengage from the limiting member 31, the handle portion 10 can enter the unlocked state, realizing the function of rotating around the X-axis relative to the connecting portion 20, and the operation is simpler; when the adjustment is completed, the elastic recovery of the elastic reset member 33 automatically pushes the locking button 32 to engage the first meshing tooth 322 and the second meshing tooth 311 to fix the handle portion 10 to the connecting portion 20, thereby ensuring the stability of the handle portion 10, and there is no need for the user to manually reset it, which is more convenient to use. In addition, through the meshing of the first meshing tooth 322 and the second meshing tooth 311, a stable locking effect can be provided, ensuring the durability and reliability of the locked state.

[0048] In order to form a positioning effect for the elastic reset member 33, a positioning rod 323 is also provided on the lock button 32, and the elastic reset member 33 is sleeved on the positioning rod 323 to form a positioning effect for the installation of the elastic reset member 33. The setting of the positioning rod 323 can also effectively prevent the elastic reset member 33 from being offset.

[0049] Among them, there is an inclined transmission between the lock button 32 and the unlocking member 40. In this way, the design of setting an inclined transmission between the lock button 32 and the unlocking member 40 can provide a smoother and more continuous force transmission during the unlocking process. The inclined transmission can gradually convert the force in the unlocking process into movement, thereby reducing sudden impact and vibration, which is beneficial to improving the service life and stability of the mechanism. In addition, by reasonably designing the angle and shape of the inclined surface, the unlocking process can be made smoother, reducing the user's strength and time, and improving the comfort and efficiency of the operation.

[0050] Specifically, the unlocking member 40 is slidably arranged on the handle portion 10 and the connecting portion 20 along the Z axis, and the unlocking member 40 is provided with a convex rib 43. The surface of the convex rib 43 is provided with an inclined surface 431 inclined toward the center of the connecting hole 201 from top to bottom. There are two inclined surfaces 431, and the size between the two inclined surfaces 431 gradually decreases from top to bottom. The two locking buttons 32 are both provided with a groove 321 for the convex rib 43 to be inserted, and the groove 321 has a matching surface 3211 that fits with the inclined surface 431. The unlocking member 40 moves upward along the Z axis and pulls the two locking buttons 32 along the X axis toward the center of the connecting hole 2001 through the convex rib 43 to disengage from the limiting member 31. At this time, the elastic reset member 33 is compressed. When the unlocking member 40 is released, the elastic recovery of the elastic reset member 33 resets the two locking buttons 32, and at the same time, the handle portion 10 is also reset through the inclined surface transmission.

[0051] It is understandable that in other embodiments, the lock button 32 and the unlocking member 40 may also be connected in a suitable manner such as a rack and pinion transmission.

[0052] In order to achieve the fixation of the auxiliary handle in the Y-axis direction after it is installed on the handheld tool, a through hole 202 connected to the connecting hole 201 is provided on the connecting part 20, and the locking structure also includes a pull rod 34, the upper end of the pull rod 34 is hingedly connected to the locking button 32, a fulcrum 341 is provided in the middle part of the pull rod 34, and a limiting protrusion 342 is provided at the lower end of the pull rod 34. The elastic action of the elastic reset member 33 pushes the locking button 32 to drive the pull rod 34 to rotate around the fulcrum 341 so that the limiting protrusion 342 passes through the through hole 202 and extends into the connecting hole 201, and the locking button 32 is pushed by the unlocking member 40 to drive the pull rod 34 to rotate around the fulcrum 341 so that the limiting protrusion 342 passes through the through hole 202 and moves out of the connecting hole 201. With such a design, the elastic action of the elastic reset member 33 can push the lock button 32 to drive the pull rod 34 to rotate around the fulcrum 341, so that the limiting protrusion 342 passes through the through hole 202 and extends into the connecting hole 201, thereby realizing a firm connection between the handle portion 10 and the connecting portion 20. This design can ensure the reliability and stability of the locking structure, thereby ensuring the safety and stability of the device. In addition, the lock button 32 is pushed by the unlocking member 40 to drive the pull rod 34 to rotate around the fulcrum 341, so that the limiting protrusion 342 passes through the through hole 202 and moves out of the connecting hole 201, and the connection between the handle portion 10 and the connecting portion 20 can be easily released, so that the user can easily unlock the connecting portion 20 and realize the rotation of the handle portion 10.

[0053] It should be noted that in order to ensure the normal operation of the auxiliary handle, a fixing groove that cooperates with the limiting protrusion 342 must be provided on the fixing rod of the tool for installing this auxiliary handle. The fixing rod is connected to the connecting hole 201. When the handle part 10 is in a locked state, the elastic reset member 33 pushes the locking button 32 to drive the pull rod 34 to rotate around the fulcrum 341 so that the limiting protrusion 342 passes through the through hole 202 and extends into the connecting hole 201, so that the limiting protrusion 342 is stuck in the fixing groove, thereby fixing the auxiliary handle. When the handle part 10 is in an unlocked state, the locking button 32 is pushed by the unlocking member 40 to drive the pull rod 34 to rotate around the fulcrum 341 so that the limiting protrusion 342 passes through the through hole 202 and moves out of the connecting hole 201, so that the limiting protrusion 342 moves out of the fixing groove, thereby unlocking the auxiliary handle. The auxiliary handle can rotate around the Y-axis.

[0054] In order to improve the stability of the fixation, two pull rods 34 are provided, and the two pull rods 34 are arranged in a mirror image along the Y axis, and a through hole 202 that cooperates with the two pull rods 34 is provided on the connecting portion 20. In this way, the design of mirroring the pull rods 34 along the Y axis can provide a more uniform and stable force transmission, thereby increasing the stability and reliability of the system. This design can ensure that the connection between the connecting portion 20 and the handle portion 10 is more uniform, reducing the instability caused by asymmetric force. In addition, the through hole 202 that cooperates with the pull rod 34 is provided on the connecting portion 20, so that the two pull rods 34 can work more coordinated, improving the balance and stability of the connection.

[0055] In order to improve the aesthetics, a decorative cover 21 is provided on the connection part 20, and the decorative cover 21 covers the connection part 20 to form a movable cavity for the pull rod 34 to rotate. In this design, the decorative cover 21 covers the connection part 20 to form a movable cavity, which can effectively protect the connection part 20 and the pull rod 34 from the influence of the external environment, such as dust, water vapor, etc., helps to prevent corrosion and damage, and prolongs the service life of the connection part 20 and the pull rod 34. Secondly, the design of the decorative cover 21 can beautify the appearance of the connection part 20.

[0056] It should be noted that the handle portion 10 includes a first handle member 102 and a second handle member 103 distributed along the Y axis, and the first handle member 102 and the second handle member 103 are detachably connected via a snap-on structure. The connecting portion 20 includes a first connecting member 203 and a second connecting member 204 distributed along the X axis, and the first connecting member 203 and the second connecting member 204 are detachably connected via a screw structure.

[0057] When in use, when it is necessary to adjust the angle of the handle portion 10 in the X-axis direction, the user pulls the unlocking member 40, and the lock button 32 is pushed by the unlocking member 40 to move along the X-axis to disengage from the limiting member 31, and the user operates the handle portion 10 to rotate around the X-axis. After the adjustment is completed, the user releases the unlocking member 40, and the elastic reset member 33 pushes the lock button 32 to engage with the limiting member 31 so that the handle portion 10 is fixedly connected to the connecting portion 20;

[0058] When it is necessary to adjust the angle of the handle part 10 in the Y-axis direction, the user pulls the unlocking member 40, and the locking button 32 is pushed by the unlocking member 40 to drive the pull rod 34 to rotate around the fulcrum 341 so that the limiting protrusion 342 passes through the through hole 202 and moves out of the connecting hole 201. The user operates the handle part 10 to rotate around the Y-axis. After the adjustment is completed, the user releases the unlocking member 40, and the elastic reset member 33 pushes the locking button 32 to drive the pull rod 34 to rotate around the fulcrum 341 so that the limiting protrusion 342 passes through the through hole 202 and extends into the connecting hole 201.

[0059] When adjusting the angle of the handle part 10 in the X-axis direction and the angle of the Y-axis direction at the same time, the user pulls the unlocking member 40, and the locking button 32 is pushed by the unlocking member 40 to move along the X-axis to disengage from the limiting member 31. At the same time, the locking button 32 is pushed by the unlocking member 40 to drive the pull rod 34 to rotate around the fulcrum 341 so that the limiting protrusion 342 passes through the through hole 202 and moves out of the connecting hole 201. The user operates the handle part 10 to rotate around the X-axis and around the Y-axis. After the adjustment is completed, the user releases the unlocking member 40, and the elastic reset member 33 pushes the locking button 32 to engage with the limiting member 31 to fix the handle part 10 with the connecting part 20.
