[0039] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes and are not intended to limit the present invention.

[0040] In the description of this application, the terms "upper" and "lower" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application.

[0041] See also Figures 1 to 7 The utility model provides a technical solution: a foldable multifunctional handle, comprising a handle body 1 and an arm 2, wherein the handle body 1 is used for holding, and the handle body 1 is boat-shaped or T-shaped or can also be other shapes, and the arm 2 has a claw buckle at one end away from the handle body 1 for connecting to a camera cage, and a mounting base 3 is provided on one side of the handle body 1, and further comprises a connecting assembly 4 for rotatably connecting the arm 2 and the mounting base 3;

[0042] A first positioning slot 21 is formed on the outer surface of the support arm 2, and a positioning pin 6 and an elastic push assembly 7 for pushing the positioning pin 6 to move are movably provided on the mounting base 3;

[0043] The movement trajectory of the positioning pin 6 intersects with the movement trajectory of the support arm 2. When the support arm 2 rotates so that the first positioning slot 21 is aligned with the positioning pin 6, the positioning pin 6 is automatically inserted into the first positioning slot 21 under the action of the elastic push component 7 to limit the rotation of the support arm 2.

[0044] The outer surface of the support arm 2 is provided with a second positioning slot 22. When the support arm 2 rotates 90 degrees, the positioning pin 6 can be inserted from the first positioning slot 21 into the second positioning slot 22 to limit the rotation of the support arm 2.

[0045] When the foldable multifunctional handle of the present invention is in use, when the handle needs to be stored, the positioning pin 6 is first pushed upward so that the positioning pin 6 disengages from the first positioning slot 21, and the positioning pin 6 squeezes the elastic push component 7 during the upward movement, and then the support arm 2 is bent to fold and the elastic push component 7 is released. The positioning pin 6 continues to resist the support arm 2 under the force of the elastic push component 7, and the support arm 2 rotates relative to the mounting base 3 through the connecting component 4 and approaches the handle body 1 to be folded. When the support arm 2 is folded and contacts the handle body 1 (folding is completed), the support arm 2 is rotated exactly ninety degrees. At this time, the second positioning slot 22 is aligned with the positioning pin 6, and the positioning pin 6 is inserted into the second positioning slot 22 under the action of the elastic push component 7 to limit the rotation of the support arm 2, thereby preventing the support arm 2 from loosening and affecting carrying.

[0046] When the handle needs to be unfolded for use, repeat the above operation to reverse-rotate the support arm 2 by ninety degrees. The handle of the present utility model can be folded when not in use to reduce the volume of the handle, which is conducive to the carrying of the handle. Moreover, the folding operation is simple. Only need to push the positioning pin 6 to move and then rotate the support arm 2, which improves the user experience of the photographer.

[0047] Please refer to Figure 3 and Figure 6 , the elastic pushing component 7 includes a mounting hole A71 opened on one side of the mounting base 3 facing the handle body 1. The mounting hole A71 is a threaded hole, and the mounting hole A71 penetrates the mounting base 3 up and down;

[0048] A mounting cylinder 72 is threadedly installed in the mounting hole A71. The top of the mounting cylinder 72 is provided with a screwing groove for screwing the mounting cylinder 72. The mounting cylinder 72 has an inner cavity 73. The opening of the inner cavity 73 faces downward, and a plug spring 74 is fixed in the inner cavity 73. The lower end of the plug spring 74 extends into the groove 46 at the top of the positioning pin 6 and abuts against the positioning pin 6 to push the positioning pin 6 to continuously abut against the support arm 2. Thus, when the support arm 2 rotates so that the positioning slot aligns with the positioning pin 6, the positioning pin 6 can automatically insert into the positioning slot under the action force generated by the deformation of the plug spring 74 to limit the rotation of the support arm 2.

[0049] Please refer to Figure 3 and Figure 4 , a through groove 8 is penetrated through the front surface of the mounting base 3 from front to back. The two ends of the through groove 8 are stepped in opening. The bottom of the through groove 8 is open, and the bottom opening faces the support arm 2. The top of the through groove 8 communicates with the mounting hole A71; ]>

[0050] Button A9s are respectively inserted at the two ends of the through groove 8. The positioning pin 6 is fixed on one of the button A9s. A clamping groove 10 is opened on the positioning pin 6. A clamping block 11 is fixed on the side of the other button A9 extending into the through groove 8. The clamping block 11 can be inserted and matched with the clamping groove 10 to connect the two button A9s into one body, which is beneficial to installing the two button A9s in the through groove 8. And a fixing member 12 is commonly penetrated through the two button A9s. The fixing member 12 is a screw. The two button A9s are fixed together by the screw to ensure the stability of the connection between the two button A9s;

[0051] The bottom of the button A9 protrudes downward to form a limiting portion 91, which is used to be inserted into the first positioning slot 21 together with the positioning pin 6 to limit the position of the support arm 2. The outward end of the button A9 is a toggle portion 92, which is used to toggle the positioning pin 6 to move the support arm 2 to release the limit;

[0052] When it is necessary to release the limit of the positioning pin 6 on the support arm 2, the button A9 is pushed upward through the toggle portion 92, and the button A9 drives the positioning pin 6 to slide upward along the through groove 8 to disengage from the positioning slot. During the movement of the positioning pin 6, the pin spring 74 is squeezed. When the positioning pin 6 disengages from the positioning slot, the support arm 2 can rotate, thereby facilitating the operation of the positioning pin 6 to move through the button A9, and ensuring the stability of the installation of the positioning pin 6 and the convenience of moving the positioning pin 6.

[0053] See also Figure 5 The mounting base 3 has two integrally formed connecting arms 41, the two connecting arms 41 are spaced apart and arranged opposite to each other at the bottom of the mounting base 3, and first through holes 42 are respectively opened on the opposite surfaces of the two connecting arms 41;

[0054] The support arm 2 is installed between the two connecting arms 41, and the upper end of the support arm 2 has a second through hole 43, and the center line of the second through hole 43 coincides with the center line of the first through hole 42. The connecting assembly 4 includes a connecting piece A44, which is a T-shaped sleeve with an internal thread. The connecting piece A44 is passed through the two through holes, and the support arm 2 is rotatably installed between the two connecting arms 41. The connecting piece A44 is threadedly connected to a connecting piece B45 for axially limiting the connecting piece A44, and the connecting piece B45 is a screw;

[0055] The support arm 2 is provided with a groove 46 on the side facing the two connecting arms 41. A gasket 47 is installed in the groove 46. The gasket 47 abuts against the connecting arm 41. The gasket 47 is made of nylon.

[0056] Threadedly connecting the connecting member B45 with the connecting member A44 can clamp the support arm 2 between the two connecting arms 41. The first through hole 42 is in the shape of a flat key groove, so that when the connecting member A44 is inserted into the connecting arm 41, the connecting member A44 will not rotate relative to the connecting arm 41, thereby preventing the connecting member B45 from rotating relative to the connecting member A44 and becoming loose, ensuring a constant damping force. By screwing the connecting member B45, the magnitude of the damping force can be adjusted. When the support arm 2 rotates, the support arm 2 rotates relative to the connecting member A44 through the second through hole 43, and the gasket 47 generates a damping force during the rotation process to stably install the support arm 2 between the two support arms 2.

[0057] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 , a mounting groove 13 is formed at the bottom of the handle body 1, a slide rail 14 is fixedly arranged in the mounting groove 13, a chute 15 is formed in the mounting base 3, and when the chute 15 is in sliding fit with the slide rail 14, the mounting base 3 can slide along the length direction of the handle body 1;

[0058] A plurality of positioning holes 16 are formed on one side of the slide rail 14 facing the mounting base 3, and a positioning assembly 17 is arranged on the mounting base 3. When the positioning assembly 17 is in plug-in fit with the positioning holes 16, the relative sliding between the mounting base 3 and the slide rail 14 can be restricted;

[0059] A mounting hole B171 is formed at the top of the mounting base 3. The positioning assembly 17 includes a limit pin 172 inserted into the mounting hole B171. The limit pin 172 can be in plug-in fit with the positioning holes 16. A connecting pipe 173 is screwed to the bottom of the limit pin 172. A screwing groove is formed at the top of the limit pin 172, which is beneficial to rotating the limit pin 172 on the connecting pipe 173. The lower end of the connecting pipe 173 extends out of the mounting hole B171, and a button B174 is fixedly arranged at the extending end;

[0060] A spring A175 is installed between the bottom of the limit pin 172 and the bottom wall of the mounting hole B171. The spring A175 is sleeved outside the connecting pipe 173. Under the action of the force generated by the deformation of the spring A175, the limit pin 172 always maintains a state of extending out of the mounting hole B171, and at this time the button B174 abuts against the bottom surface of the mounting base 3;

[0061] When it is necessary to adjust the relative position between the support arm 2 and the handle body 1 to change the relative mounting position of the camera and the handle body 1, the button B174 is toggled downward. The button B174 drives the limit pin 172 to move downward synchronously through the connecting pipe 173, so that the limit pin 172 is separated from the positioning hole 16 to release the horizontal limit of the mounting base 3. At this time, the mounting base 3 can slide horizontally on the slide rail 14 to adjust the relative position between the camera and the handle body 1, so that the handle body 1 meets the shooting and control requirements;

[0062] After the adjustment is completed, the button B174 is released. The button B174 is pushed upward as a whole under the acting force generated by the deformation of the spring A175, and the limit pin 172 is inserted into the positioning hole 16 to fix the mounting base 3 on the slide rail 14.

[0063] Please refer to Figure 3 and Figure 6 , a mounting hole C176 is also provided at the top of the mounting base 3. A spring B177 is fixed in the mounting hole C176. A positioning steel ball 178 is fixed at the top of the spring B177. The positioning steel ball 178 can extend into the positioning hole 16 under the acting force generated by the deformation of the spring B177. When the relative position between the camera and the handle body 1 is finally adjusted by sliding the mounting base 3, when the mounting base 3 slides, the slide rail 14 squeezes the positioning steel ball 178 out of the positioning hole 16 and compresses the spring B177. When the movement of the mounting base 3 causes the positioning steel ball 178 to align with the positioning hole 16, the positioning steel ball 178 extends into the first positioning hole 16 again under the acting force generated by the deformation of the spring B177 to further limit the relative sliding between the mounting base 3 and the slide rail 14, thereby ensuring the stability of the installation of the mounting base 3. And during the process of adjusting the position of the support arm 2, the continuous insertion and cooperation of the positioning steel ball 178 with the positioning hole 16 can play a role of limiting and prompting, which can avoid excessive force during the adjustment of the mounting base 3 resulting in too far a sliding distance, and can accurately adjust the relative position between the support arm 2 and the handle body 1.

[0064] Finally, it should be noted that the above embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited by this. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
