[0036] The utility model provides a Velcro extension bracket structure, which optimizes the bracket structure and utilizes the Velcro characteristics to assist in the locking connection of the bracket body; after the hook surface of the Velcro and the fur surface of the Velcro are pasted together, a fixed state with a certain shock-absorbing effect is formed to reduce the vibration or jitter generated during vehicle driving; a sliding hole of a certain length is arranged on the support rod of the connecting part, and the connecting part can be moved back and forth during use, which is convenient for users to operate the mobile phone or other digital products on the magnetic suction part, and is very practical; a universal ball assembly is provided on the shell of the magnetic suction part or on the support rod of the connecting part, so that the magnetic suction part can be rotated at multiple angles, and the viewing angle of the mobile phone screen fixed on the magnetic suction part can be adjusted, which is very convenient; the locking mechanism can be used to adjust the locking state, unlocking state or detachable state of the connecting part, and a retaining spring is provided at one end of the screw on the locking mechanism to prevent the screw from falling off.

[0037] Figure 1-Figure 5 The figure shows the overall structure of a Velcro extension bracket structure of the utility model. Figure 1-Figure 5 The main structure of this embodiment includes: the bracket body 1 includes a magnetic attraction part 11, a connecting part 12 and a fixing part 13 from top to bottom; the connecting part 12 includes at least two groups of support rods 121, and the two groups of support rods 121 are rotatably connected by a rotating shaft with a certain damping effect. When in use, the support rods 121 connected to the magnetic attraction part 11 can be pushed and pulled to rotate, so as to adjust the front and rear telescopic state of the magnetic attraction part 11. The rotation with a certain damping sense can prevent the support rods 121 from rotating by themselves under the gravity of the magnetic attraction part 11 and the mobile phone. A non-closed portion of a certain length is opened along the length direction on the support rods 121 close to the fixing part 13. The fixing part 13 is slidably and detachably connected to the sliding hole 1211, forming an effect of the connecting part 12 extending and retracting or moving forward and backward. The fixing part 13 includes a fixing plate 131 and a Velcro A surface 132 fixed on the fixing plate 131. The Velcro A surface 132 is a hook surface of the Velcro or a fur surface of the Velcro. The fixing part 13 also includes a Velcro B surface 133. The Velcro B surface 133 is used to be fixed on the central control or on a plane in the car. The Velcro B surface 133 is a fur surface of the Velcro or a hook surface of the Velcro. When the Velcro A surface 132 and the Velcro B surface 133 are in contact and bonded with each other, the bracket body 1 is in an installed and fixed state.

[0038] In this embodiment, the sliding hole 1211 is a non-closed structure. The sliding hole 1211 is opened at one end of the support rod 121 connected to the fixing part 13. The sliding hole 1211 extends to the end of the support rod 121 to form an open state, which can facilitate the disassembly and installation of the fixing part 13.

[0039] In some embodiments, as shown in the attached Figure 2As shown, the magnetic attraction part 11 includes a universal ball assembly 113 arranged on the shell 111 or the support rod 121. The magnetic attraction part 11 is rotatably connected to one end of the connecting part 12 through the universal ball assembly 113. The universal ball assembly 113 includes a universal ball head, a fastening nut and a ball head groove. The universal ball head passes through the fastening nut and is inserted in the ball head groove. The fastening nut is used to perform angle fixing and other operations. In this embodiment, the universal ball head is fixedly connected to the support rod 121 at one end of the connecting part 13, and the ball head groove is arranged on the shell 111 of the magnetic attraction part 11. The magnetic attraction part 11 includes a shell 111 and a magnetic attraction body 112 embedded in the shell 111. In this embodiment, a decorative cover 10 is also arranged on the surface of the magnetic attraction body 112. The magnetic attraction body 112 is arranged to be a magnet or an iron sheet or a structure with a certain magnetic attraction effect. The magnetic attraction part 11 is magnetically connected to the magnet or iron sheet on the handheld device by arranging the magnetic attraction body 112 to fix the state of the handheld device.

[0040] In some embodiments, as shown in the attached Figure 2-5 As shown, the Velcro B surface 133 also includes a substrate 1331 fixedly connected to the Velcro B surface 133, and the substrate 1331 is provided with a self-adhesive sticker. The Velcro B surface 133 is fixed on the central console or plane in the vehicle through the self-adhesive sticker on the substrate 1331. The substrate 1331 is made of a material with a certain hardness, so that the bracket body 1 has a certain supporting and stabilizing effect when it is in a fixed state, wherein the Velcro B surface is fixedly set on the upper surface of the substrate 1331, and the self-adhesive sticker is evenly coated on the lower surface of the substrate 1331.

[0041] In some embodiments, as shown in the attached Figure 2-5As shown, the fixing part 13 also includes a locking mechanism, and the fixing part 13 slides forward and backward or left and right with the corresponding support rod 121 through the sliding hole 1211. By setting the locking mechanism, the locking state adjustment and unlocking state adjustment or detachable state adjustment when the fixing part 13 slides forward and backward or left and right can be realized. The locking mechanism includes a screw 134, a nut 135 and a retaining spring 136. One end of the screw 134 passes through the sliding hole 1211 and is threadedly connected to the nut 135, and the nut 135 is adapted to the screw 134; a through hole 1332 is provided on the fixing plate 131, and the nut 135 is fixedly connected in the through hole 1332. The screw 134 has an external thread 1341 of a certain length and a screw head fixedly connected to one end of the external thread 1341. The length of the external thread 1341 is the rotation adjustment stroke length of the screw 134, and the retaining spring 136 is clamped on the screw 134. When the locking mechanism is in the unlocked state or the detachable state, the connecting part 12 can be pushed to the appropriate position, and the screw 134 can be tightened to fix the moving position of the connecting part 12, or the connecting part 12 can be completely removed from the sliding hole 1211. When the fixing part 13 is in the locked state, the screw 134 is rotated left or right, and the screw 134 rotates progressively in the direction of the retaining spring 136, and the retaining spring 136 is away from the nut 135. At the same time, the screw 134 pulls the fixing plate 131 in the opposite direction, and the screw head on the screw 134 contacts the corresponding support rod 121, forming a clamping and pressing state of the fixing plate 131 and the screw head on the support rod 121;

[0042] In this way, the limiting function of the retaining spring 136 can prevent the screw rod 134 from falling off when the screw rod 134 is excessively twisted.

[0043] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
