[0010] The present invention is further configured such that: the locking member is slidably disposed on the latching member or the grip, and the locking member can slide between the latching member and the grip and restrict the relative rotation of the latching member and the grip.

[0011] The present invention is further configured such that: the snap-fit ​​component is rotatably mounted on the handle via a hinge rod, the locking component is slidably mounted on the snap-fit ​​component, and the locking component is provided with a limiting groove adapted to the hinge rod, the hinge rod cooperates with the limiting groove and guides and limits the movement of the locking component.

[0012] The present invention is further configured such that: the locking member is provided with a locking part, and the snap-fit ​​member is provided with a snap-fit ​​groove adapted to the locking part; the locking part and the snap-fit ​​groove cooperate to fix the snap-fit ​​member and the locking member relatively, and to keep the snap-fit ​​member and the snap-fit ​​part in cooperation.

[0013] The present invention is further configured such that: the snap-fit ​​component is provided with a mounting groove for installing a locking component, the locking component includes a mounting part passing through the mounting groove, one end of the mounting part is provided with a control part extending outward from the periphery of the mounting groove, the locking part is provided on the side of the control part near the snap-fit ​​component, and the locking part can be moved into the mounting groove and abut against the side of the mounting groove, thereby restricting the relative movement between the locking component and the snap-fit ​​component.

[0014] The present invention is further configured such that: a second guide surface is provided on the side of the mounting groove, and the locking part can be guided through the second guide surface to pass out of the mounting groove.

[0015] The present invention is further configured such that: the grip is provided with friction protrusions, the friction protrusions can abut against the locking member and restrict the relative movement of the locking member, the snap-fit ​​member and the grip, and the end of the friction protrusions is provided with a first guide surface, the locking member can be guided to move to the side of the friction protrusions through the first guide surface.

[0018] The advantages of this utility model compared to the prior art are:

[0019] 1. In this utility model, the extension rod is automatically extended from the handle by the first elastic element, which facilitates the automatic extension of the telescopic baton and makes it convenient for the user. The structure also keeps the extension rod retracted in the handle through the snap-fit, which facilitates the storage and transportation of the telescopic baton. The locking element can prevent the snap-fit ​​from being accidentally touched during storage and transportation, which would cause the extension rod to extend from the handle unexpectedly. Since the locking element is movably set on the snap-fit, the user can lock the snap-fit ​​and the locking element with one hand, which makes it easy for the user to quickly control the telescopic baton and make it convenient for the user.

[0020] 2. The driving surface in this invention facilitates the rapid retraction of the extension rod into the handle. During this process, the user does not need to control the movement of the locking component, which facilitates the rapid retraction of the telescopic baton and makes it convenient for the user. The rotating locking component allows the user to control its movement. Since the locking component is slidably mounted on the locking component or the handle, and the movement directions of the locking component and the locking component are different, the locking component and the locking component are not likely to be triggered simultaneously during storage and transportation. This prevents the extension rod from accidentally extending out of the handle during storage and transportation, making the storage and transportation of the telescopic baton convenient. In this structure, the locking component is rotatably mounted on the handle by the hinge rod, and the movement of the locking component is guided and limited by the hinge rod and the limiting groove. This simplifies the structure of the telescopic baton and facilitates its assembly and production.

[0021] 3. The locking part and the slot in this utility model have a simple structure, which facilitates the relative fixation of the locking part and the latching part, avoids accidental relative movement between the locking part and the latching part, and is conducive to the stable connection between the latching part and the latching part, making it convenient for the storage and transportation of the telescopic baton. Since the locking part is set in the mounting slot, the locking part and the latching part are installed together, which makes it convenient for the user to quickly control the locking part and the latching part, and to control the telescopic baton to extend quickly. The setting of the control part not only makes it convenient for the user to drive the locking part, but also prevents foreign objects from entering the mounting slot. Since the locking part can abut against the side of the mounting slot, it prevents the free movement of the locking part from affecting the normal movement of the latching part during the extension of the telescopic baton, making it convenient for the user. The setting of the second guide surface makes it convenient for the locking part to pass through the mounting slot, which facilitates the driving control of the locking part.

[0022] 4. The friction protrusion in this utility model can restrict the relative movement of the locking member, preventing the locking member from moving during use and causing the latching member to rotate freely with the handle. It also prevents the latching member from being accidentally touched during storage and transportation, thus preventing the extension rod from accidentally extending out of the handle. This facilitates the storage and transportation of the telescopic baton. The first guide surface facilitates the connection and cooperation between the locking member and the friction protrusion, making it convenient for the user. The friction protrusion and the locking member positioned between the two mounting protrusions facilitate the connection and cooperation between the friction protrusion and the locking member, preventing the friction protrusion and the locking member from being misaligned during use.

[0023] 5. The first rod, the second rod, and the second elastic element in this utility model help to reduce the volume of the telescopic baton after it is retracted, making it convenient for storage and transportation. Furthermore, since the handle is slidably connected to the second rod and the locking part is located on the first rod, the locking part and the locking part can cause the first rod to retract into the second rod and the second rod to retract into the handle. The structure is simple and facilitates the stable retraction of the telescopic baton. Attached Figure Description

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0038] See Figures 1 to 11 As shown, an automatically extending telescopic baton includes a handle 1, an extension rod 2 and a first elastic element 5 movably disposed in the handle 1. The first elastic element 5 can drive the extension rod 2 to extend out of the handle 1. The handle 1 is provided with a locking element 3 and a third elastic element 6. The extension rod 2 is provided with a locking part 24. The third elastic element 6 can drive the locking element 3 to rotate and cooperate with the locking part 24, thereby keeping the extension rod 2 stored in the handle 1. By controlling the movement of the locking element 3, the locking element 3 can disengage from the locking part 24, and the first elastic element 5 can drive the extension rod 2 to extend out of the handle 1. In this structure, the extension rod 2 is automatically extended out of the handle 1 by the first elastic element 5, which facilitates the automatic extension of the telescopic baton and makes it convenient for users to use. In addition, the structure keeps the extension rod 2 retracted in the handle 1 by the locking element 3, which facilitates the storage and transportation of the telescopic baton.

[0039] A locking element 4 is movably provided on the latching member 3. The locking element 4 can restrict the relative movement between the latching member 3 and the handle 1, and keep the latching member 3 and the latching part 24 in cooperation. The setting of the locking element 4 can prevent the latching member 3 from being accidentally touched during storage and transportation, which would cause the extension rod 2 to extend accidentally from the handle 1. This facilitates the storage and transportation of the telescopic baton. Since the locking element 4 is movably provided on the latching member 3, the user can lock the element 4 and the latching member 3 with one hand, which makes it easy for the user to quickly control the telescopic baton and make it convenient for the user to use.

[0040] In this invention, the latching member 3 and / or the latching part 24 are provided with an inclined driving surface 25. The latching part 24 abuts against the driving surface 25, or the driving surface 25 abuts against the latching part 24, which drives the latching member 3 to move, thereby enabling the latching member 3 and the latching part 24 to quickly engage. The driving surface 25 facilitates the rapid retraction of the extension rod 2 into the handle 1. During this process, the user does not need to control the movement of the latching member 3, which facilitates the rapid retraction of the telescopic rod and makes it convenient for the user. In this embodiment, it is preferable that both the latching member 3 and the latching part 24 are provided with a driving surface 25.

[0041] The latching member 3 is rotatably mounted on the handle 1, and the locking member 4 is slidably mounted on the latching member 3 or the handle 1. The locking member 4 can slide between the latching member 3 and the handle 1 and restrict the relative rotation of the latching member 3 and the handle 1. The rotatably mounted latching member 3 makes it easy for the user to control the movement of the latching member 3. Since the locking member 4 is slidably mounted on the latching member 3 or the handle 1, the movement directions of the latching member 3 and the locking member 4 are different. During storage and transportation, the latching member 3 and the locking member 4 are not easily triggered at the same time, which prevents the extension rod 2 from accidentally extending out of the handle 1 during storage and transportation, and facilitates the storage and transportation of the telescopic baton.

[0042] In this embodiment, the snap-fit ​​component 3 is rotatably mounted on the handle 1 via the hinge rod 12, and the locking component 4 is slidably mounted on the snap-fit ​​component 3. The locking component 4 is provided with a limiting groove 44 that is adapted to the hinge rod 12. The hinge rod 12 cooperates with the limiting groove 44 and guides and limits the movement of the locking component 4. In this structure, the hinge rod 12 can install the snap-fit ​​component 3 and the locking component 4 on the handle 1, which helps to simplify the structure of the telescopic baton and facilitates the assembly and production of the telescopic baton.

[0043] The locking member 4 is provided with a locking part 42, and the snap-fit ​​member 3 is provided with a snap-fit ​​groove 32 that is adapted to the locking part 42. The locking part 42 and the snap-fit ​​groove 32 cooperate to fix the snap-fit ​​member 3 and the locking member 4 relatively, and to keep the snap-fit ​​member 3 and the snap-fit ​​part 24 in cooperation. The structure of the locking part 42 and the snap-fit ​​groove 32 is simple, which facilitates the relative fixation of the snap-fit ​​member 3 and the locking member 4, avoids the locking member 4 from accidentally moving relative to the snap-fit ​​member 3, and is conducive to the stable connection of the snap-fit ​​member 3 and the snap-fit ​​part 24, which facilitates the storage and transportation of the telescopic baton.

[0044] The snap-fit ​​component 3 described in this utility model is provided with an installation groove 31 for installing the locking component 4. This structure allows the locking component 4 and the snap-fit ​​component 3 to be installed together, making it convenient for the user to quickly control the locking component 4 and the snap-fit ​​component 3, and making it convenient for the user to control the telescopic baton to extend quickly.

[0045] The locking member 4 includes a mounting part 43 that passes through the mounting groove 31. One end of the mounting part 43 is provided with a control part 41 that extends outward from the mounting groove 31. The locking part 42 is located on the side of the control part 41 near the latching member 3. The locking part 42 can be moved into the mounting groove 31 and abut against the side of the mounting groove 31, thereby restricting the relative movement between the locking member 4 and the latching member 3. The setting of the control part 41 not only makes it convenient for the user to drive the locking member 4, but also prevents foreign objects from entering the mounting groove 31. Furthermore, since the locking part 42 can abut against the side of the mounting groove 31, it prevents the free movement of the locking member 4 during the extension of the telescopic rod from affecting the normal movement of the latching member 3, making it convenient for the user to use.

[0046] Preferably, a second guide surface 33 is provided on the side of the mounting groove 31. The locking part 42 can be guided through the second guide surface 33 to pass through the mounting groove 31. The second guide surface 33 facilitates the locking part 42 to pass through the mounting groove 31 and facilitates the driving control of the locking part 4.

[0047] The handle 1 is provided with friction protrusions 13, which can abut against the locking member 4 and restrict the relative movement of the locking member 4, the latching member 3, and the handle 1. The friction protrusions 13 can restrict the relative movement of the locking member 4, prevent the latching member 3 from rotating freely with the handle 1 during use, and prevent the latching member 3 from being accidentally touched during storage and transportation, which would cause the extension rod 2 to extend accidentally from the handle 1, thus facilitating the storage and transportation of the telescopic baton.

[0048] The friction protrusion 13 has a first guide surface 14 at its end. The locking member 4 can be guided to move to the side of the friction protrusion 13 through the first guide surface 14. The first guide surface 14 facilitates the connection and cooperation between the locking member 4 and the friction protrusion 13, making it convenient for the user. In this embodiment, the mounting part 43 can abut against the friction protrusion 13 and restrict the relative movement of the locking member 4, the snap-fit ​​member 3, and the handle 1. Preferably, one end of the mounting part 43 is provided with a support part 45. The support part 45 can pass between the snap-fit ​​member 24 and the handle 1 and restrict the relative rotation of the snap-fit ​​member 3 and the handle 1. The support part 45 is provided with a third guide surface 46. The third guide surface 46 can cooperate with the first guide surface 14 to move the support part 45 and the mounting part 43 to the side of the friction protrusion 13.

[0049] In this embodiment, the grip 1 extends to form two mounting protrusions 11 on its side, and a friction protrusion 13 is disposed between the two mounting protrusions 11. The locking member 4 passes through the two mounting protrusions 11 and cooperates with the friction protrusion 13. The friction protrusion 13 and the locking member 4 disposed between the two mounting protrusions 11 facilitate the connection and cooperation between the friction protrusion 13 and the locking member 4, and prevent the friction protrusion 13 and the locking member 4 from being misaligned during use.

[0050] Both mounting protrusions 11 are inserted into the mounting groove 31, and the hinge rod 12 is detachably connected to the two mounting protrusions 11 respectively. The mounting groove 31 is provided with hinge holes 34 on both sides for connecting to the hinge rod 12.

[0051] The extension rod 2 includes a first rod body 21 and a second rod body 22 that are slidably connected. The handle 1 is slidably connected to the second rod body 22. A first elastic element 5 can drive the second rod body 22 to extend out of the handle 1. A second elastic element 23 is provided between the first rod body 21 and the second rod body 22. The second elastic element 23 can drive the first rod body 21 and the second rod body 22 to extend relative to each other. A locking part 24 is provided on the first rod body 21. The locking element 3 and the locking part 24 can cause the first rod body 21 to retract into the second rod body 22. In section 2, the second rod 22 is retracted into the handle 1. The arrangement of the first rod 21, the second rod 22, and the second elastic member 23 helps to reduce the volume of the telescopic baton after it is retracted, making it convenient for storage and transportation. Since the handle 1 is slidably connected to the second rod 22, and the locking part 24 is set on the first rod 21, the locking member 3 and the locking part 24 can make the first rod 21 retract into the second rod 22, and make the second rod 22 retract into the handle 1. The structure is simple and facilitates the stable retraction of the telescopic baton.

[0052] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
