The locking assembly 300 includes a stop block 310 and a button 320. The stop block 310 and the button 320 are detachably connected. The stop block 310 abuts against the connecting seat 200 so that the connecting seat 200 and the shell are rotated and locked. When unlocking, the button 320 is pressed, and the button 320 moves relative to the stop block 310 and simultaneously drives the stop block 310 to rotate relative to the shell 100, so that the stop block 310 is separated from the connecting seat 200, thereby the connecting seat 200 and the shell 100 are rotationally unlocked. Pressing the button 320 can quickly realize the rotational unlocking between the connecting seat 200 and the shell 100. In addition, the stop block 310 and the button 320 are detachably connected and relatively movable, so that the stop block 310 can be separated from the installation cavity, so that the stop block 310 can be easily replaced after wear.

Referring to Figures 3 and 4, a rotating hole 220 is provided at one end of the connecting base 200 close to the shell 100, and a rotating shaft 150 is relatively provided on the shell 100. The rotating shaft 150 is embedded in the rotating hole 220, so that the connecting base 200 can rotate relative to the shell 100 around the rotating shaft 150. It can be understood that the rotating hole 220 can also be set on the shell 100, and the rotating shaft 150 is set on the connecting base 200, as long as the connecting base 200 can rotate relative to the shell 100.

The connecting base 200 is provided with a latch tooth 210 at one end close to the shell 100, and the latch teeth 210 are circumferentially distributed on the outer surface of the rotating hole 220. The stop block 310 is provided with a latch tooth groove 314 on the side facing the latch tooth 210, and the latch tooth groove 314 matches the latch tooth 210. When the stop block 310 abuts against the latch tooth 210, the latch tooth 210 is embedded in the latch tooth groove 314, so that the stop block 310 engages with the latch tooth 210, thereby locking the connecting base 200 relative to the shell 100 for rotation. The stop block 310 can engage with the latch teeth 210 at different positions, so that the connecting base 200 can be rotated and positioned to different angles.

The button 320 can rotate and unlock the connection base 200 relative to the housing 100. The first rotating shaft 311 is provided at one end of the stop block 310 close to the latch 210. The first rotating shaft 311 is fixed relative to the stop block 310. The housing 100 is relatively provided with a first rotating groove 160. The first rotating shaft 311 is inserted into the first rotating groove 160 and can rotate relative to the housing 100. When the angle between the connection base 200 and the housing 100 needs to be adjusted, the button 320 is pressed, and the button 320 is relatively fixed to the stop block. 310 moves, and the button 320 simultaneously drives the stop block 310 to rotate around the first rotating axis 311, so that the stop block 310 rotates in the direction away from the latch tooth 210 and separates from the latch tooth 210, and the connecting base 200 and the shell 100 are rotated and unlocked, so that the connecting base 200 can rotate relative to the rotating axis 150 to adjust the use angle of the connecting base 200. It should be noted that the first rotating axis 311 can also be set in the shell 100, and the first rotating groove 160 is set on the stop block 310.

With reference to FIGS. 2 and 3 , the button 320 is provided with a connecting portion 321, a pressing portion 322 and a driving portion 323. The connecting portion 321 is located between the pressing portion 322 and the driving portion 323. The connecting portion 321 is rotatably connected to the shell 100 so that the button 320 can rotate relative to the shell 100 in the mounting cavity 110. The shell 100 is provided with an opening 170, which is communicated with the mounting cavity 110. The pressing portion 322 can extend out of the mounting cavity 110 through the opening 170 for the user to press. When the user presses the pressing portion 322, part of the structure of the pressing portion 322 retracts into the mounting cavity 110. At the same time, under the action of the lever, the pressing portion 322 can drive the driving portion 323 to rotate around the connecting portion 321, and then the driving portion 323 drives the stop block 310 to rotate around the first rotating axis 311 in a direction away from the latch tooth 210, and the stop block 310 is separated from the latch tooth 210, so that the connecting seat 200 is rotated and unlocked.

The locking assembly 300 also includes an elastic member 330, which can restore the pressing portion 322 to its original state after being pressed. The elastic member 330 is disposed at the bottom of the mounting cavity 110, and one end of the elastic member 330 in the elastic direction abuts against the pressing portion 322, and the other end of the elastic member 330 in the elastic direction abuts against the bottom wall of the mounting cavity 110. When unlocking, the pressing portion 322 is pressed, and part of the structure of the pressing portion 322 retracts into the mounting cavity 110, the stop block 310 is separated from the latch tooth 210, and the elastic member 330 is deformed and generates a force opposite to the pressing direction. When the external force is removed, the elastic member 330 abuts against the pressing portion 322 and causes the pressing portion 322 to extend out of the opening 170 around the connecting portion 321 Rotate, and at the same time, under the action of the lever, the driving part rotates around the connecting part 321 in the opposite direction to the pressing part 322, so that the stop block 310 rotates around the first rotating axis 311 in the direction close to the latch tooth 210, until the stop block 310 abuts and engages with the latch tooth 210, and the connecting seat 200 and the shell 100 are rotated and locked. It should be noted that in other embodiments, in order to avoid damage caused by multiple pressing of the elastic member 330, the elastic member 330 can also be replaced by two magnets with the same magnetic poles. For example, two magnets with the same magnetic poles are respectively arranged on the bottom wall of the mounting cavity 110 and the pressing part 322, so that the two magnets form a repulsive force, and when the pressing part 322 is pressed, the pressing part 322 is driven to restore to its initial state.

Referring to Figure 4, the connecting portion 321 is provided with a second rotating groove 3211, and the shell 100 is provided with a second rotating axis 140. The second rotating axis 140 and the second rotating groove 3211 are both located between the pressing portion 322 and the driving portion 323. The second rotating axis 140 is arranged in the second rotating groove 3211 so that the button 320 can rotate around the second rotating axis 140. When the pressing portion 322 is pressed, the second rotating axis 140 can be used as a lever fulcrum to make the driving portion 323 tilt up under the action of the lever, thereby driving the stop block 310 to rotate around the first rotating axis 311. It should be noted that the second rotating groove 3211 can also be arranged on the shell 100, and the second rotating axis 140 is arranged on the connecting portion 321.

4 and 5, the driving portion 323 is provided with a lifting shaft 3231, and a lifting track 312 is provided on the side of the stop block 310 away from the latch tooth 210. The lifting track 312 is a hole-shaped structure that penetrates the stop block 310. The lifting shaft 3231 is provided on the lifting track 312, and the lifting shaft 3231 contacts the inner wall of the lifting track 312. When the pressing portion 322 is pressed, the lifting shaft 3231 rotates around the second rotating shaft 140 under the action of the lever. The rotation trajectory of the lifting shaft 3231 is an arc. The lifting shaft 3231 can move in the lifting track 312 during the lifting process and abut against the lifting track 312 upward. The inner wall of the lifting track 312 enables the stop block 310 to obtain a force to rotate around the first rotating shaft 311, thereby causing the stop block 310 to rotate and disengage from the latch tooth 210. It should be noted that the lifting track 312 can also be a groove-like structure that does not penetrate the stop block 310. For example, the openings at both ends of the lifting track 312 are in a closed state, and the lifting shaft 3231 is arranged in the lifting track 312. The two ends of the lifting shaft 3231 in the axial direction are respectively in contact with the groove wall of the lifting track 312, so that the lifting shaft 3231 will not shake along the axial direction in the lifting track 312, thereby making the lifting shaft 3231 more stable when the lifting stop block 310 rotates.

The width of the lifting track 312 is greater than the diameter of the lifting shaft 3231. During the lifting process of the lifting shaft 3231, the moving trajectory of the lifting shaft 3231 can be decomposed into the up and down directions and the left and right directions. The width of the lifting track 312 is greater than the diameter of the lifting shaft 3231, so that the lifting track 312 can allow the lifting shaft 3231 to move left and right during the lifting process, thereby preventing the lifting shaft 3231 from being stuck by the inner wall of the lifting track, resulting in an inability to continue lifting upward.

The inner wall of the lifting track 312 is provided with a positioning groove 3121, and the positioning groove 3121 is used for accommodating and positioning the lifting shaft 3231. When the pressing portion 322 is pressed, the lifting shaft 3231 rotates, and the lifting shaft 3231 slides out of the positioning groove 3121 and moves in the lifting track 312 to lift the stop block 310. When the external force on the pressing portion 322 is removed, the lifting shaft 3231 rotates in the opposite direction under the action of the elastic member 330 until the stop block 310 and the latch tooth 210 are engaged. The lifting shaft 3231 abuts and engages, and at this time, the lifting shaft 3231 slides into the positioning groove 3121 to position the lifting shaft 3231 relative to the stop block 310. The groove wall of the positioning groove 3121 is tilted, and the inclined extension direction of the groove wall of the positioning groove 3121 is the same as the lifting trajectory of the lifting shaft 3231, so that the lifting shaft 3231 can slide into or out of the positioning groove 3121 along the groove wall of the positioning groove 3121 when rotating, and the groove wall of the positioning groove 3121 will not block the rotation of the lifting shaft 3231.

The stop block 310 is provided with a rotation space 313, and the rotation space 313 is arranged on a side of the stop block 310 close to the button 320. The rotation space 313 is connected to the lifting track 312, and the driving part 323 can be arranged in the rotation space 313 through the opening of the rotation space 313. When the driving part 323 rotates around the connecting part 321, the rotation space 313 allows the driving part 323 to move relative to the stop block 310.

The stop block 310 and the button 320 are detachably connected, and the driving part 323 is provided with a mounting hole 3232. The lifting shaft 3231 passes through and is arranged in the mounting hole 3232. When the lifting shaft 3231 passes through the lifting rail 312 and the mounting hole 3232 respectively, the stop block 310 and the button 320 are movably connected. When the lifting shaft 3231 is separated from the lifting rail 312 and the mounting hole 3232 respectively, the stop block 310 is separated from the button 320, so that the stop block 310 can be separated from the mounting cavity 110 for easy replacement.

Specifically, the shell 100 includes a first shell 120 and a second shell 130 that are relatively snapped together. The first shell 120 and the second shell 130 enclose an installation cavity 110. The first shell 120 and the second shell 130 are symmetrically arranged. The locking assembly 300 is located between the first shell 120 and the second shell 130. When the stop block 310 needs to be removed, the first shell 120 and the second shell 130 are separated, and the lifting shaft 3231 is respectively separated from the lifting track 312 and the installation hole 3232. The stop block 310 can be relatively separated from the button 320, so that the stop block 310 can be easily replaced after wear.

Referring to Figure 4, the shell 100 is provided with a mounting position 400 at one end away from the connecting seat 200. The mounting position 400 is used to install a shooting device or a photography auxiliary device. In the present embodiment, the mounting position 400 is a threaded connection structure, and the connection and disassembly with the shooting device are achieved by rotating the threaded connection rod. It should be noted that in other embodiments, the mounting position 400 may also be other connection structures.
