The outer wall of the rotating sleeve 33 is annularly distributed with mounting holes 37, and locking beads 38 are placed in the mounting holes 37. The bottom surface of the top cover 310 is detachably connected to a rotating cylinder 311, and the outer wall of the rotating cylinder 311 is provided with an annular rotating groove 312. Specifically, the rotating groove 312 is an isosceles trapezoidal groove.

Specifically, the inner cavity of the rotating sleeve 33 is a stepped through hole, and the lower positioning plate 34 is a stepped disc. The lower positioning plate 34 is matched with the stepped through hole in the rotating sleeve 33 by an axial hole, and the lower positioning plate 34 is connected to the chassis 31 by bolts, and only the rotating sleeve 33 is retained to rotate in the horizontal direction. The rotating drum 311 and the upper positioning plate 313 can be detachably connected to the top cover 310 through the upper positioning plate 313. Specifically, the rotating drum 311 and the upper positioning plate 313 can be used as an integral structure with a U-shaped cross-section, or the upper positioning plate 313 is a stepped disc, and a stepped through hole is processed in the rotating drum 311. The upper positioning plate 313 is accommodated in the rotating drum 311, and the upper positioning plate 313 is connected to the top cover 310 by bolts. The rotating drum 311 can be rotatably positioned by the lower positioning plate 34, and the rotating drum 311 can be positioned and installed by the upper positioning plate 313, which is more convenient for disassembly and assembly.

[0034] Among them, the lower positioning plate 34 is provided with a threaded hole 315 on the shaft section that passes through the chassis 31, and a connecting bolt 314 is rotatably installed between the upper positioning plate 313 and the top cover 310. Specifically, a stepped through hole is provided in the middle of the upper positioning plate 313, and the head of the connecting bolt 314 is sunk into the stepped through hole set in the middle of the upper positioning plate 313, and the handle passes through the top cover 310. The connecting bolt 314 is threadedly connected to the bottom surface of the scanner 1, and can be connected to the scanner 1 through the connecting bolt 314 to connect the top cover 310 of the quick release mechanism 3 to the scanner 1. In addition, when multiple quick release mechanisms 3 need to be assembled in parallel, the quick release mechanism 3 at the bottom is threadedly connected to the threaded hole 315 of the quick release mechanism 3 at the top through the connecting bolt 314.

[0035] Furthermore, the top rings of the locking sleeve 32 and the rotating sleeve 33 are evenly distributed with locating pins 316. Specifically, the locking sleeve 32 and the rotating sleeve 33 are both provided with annularly distributed countersunk holes, and the locating pins 316 are inserted into the countersunk holes. The locating pins 316 are rigidly installed, or a spring is placed at the bottom end of the locating pins 316 to elastically install the locating pins 316. The outer edge of the bottom surface of the top cover 310 is detachably connected to a pressure block 317 corresponding to the locking sleeve 32. The pressure block 317 is provided with a guide groove 318 from shallow to deep. Specifically, the guide groove 318 is arc-shaped, and the guide groove 318 cooperates with the locating pin 316 at the top of the locking sleeve 32. The locating pin 316 at the top of the rotating sleeve 33 penetrates the top cover 310. 10 and extends outward. Specifically, the bottom surfaces of the scanner 1 and the bottom surfaces of the chassis 31 are both provided with countersunk holes corresponding to the locating pin 316 at the top of the rotating sleeve 33, so that the locating pin 316 at the top of the locking sleeve 32 can be abutted by the guide groove 318 in the pressing block 317. When the scanner 1 is installed, the pressing block 317 presses down the locating pin 316 at the top of the locking sleeve 32, and drives the locating pin 316 through the guide groove 318 from shallow to deep, thereby driving the locking sleeve 32 to deflect. During the deflection of the locking sleeve 32, the unlocking groove 39 disengages from the locking bead 38, and the inner wall abuts the locking bead 38 to lock the rotating drum 311. The locking sleeve 32 is manually rotated in the opposite direction, and the rotating drum 311 is unlocked through the cooperation of the guide groove 318 and the locating pin 316, so that the operation is more convenient.

[0036] Among them, the bottom surface of the chassis 31 and the bottom surfaces of the locking sleeve 32 and the rotating sleeve 33 are all provided with an annular track groove 35, and the ball 36 is rolledly arranged in the track groove 35, so that the ball 36 can be accommodated by the matching track groove 35, and then the locking sleeve 32 and the rotating sleeve 33 are supported by the ball 36 to form a rolling support, which makes it easier to rotate the scanner 1 and adjust the horizontal steering angle, and the rotation adjustment is more stable.

[0037] In this embodiment, the rotating cylinder 311 of the quick release mechanism 3 is threadedly connected to the bottom surface of the scanner 1 through the connecting bolt 314, and the chassis 31 is connected to the bracket 2 through the threaded hole 315. The locking sleeve 32 is rotated to make the unlocking groove 39 correspond to the mounting hole 37. When the rotating cylinder 311 is inserted into the rotating sleeve 33, the positioning pin 316 at the top of the rotating sleeve 33 cooperates with the top cover 310 to synchronize the rotating sleeve 33 and the rotating cylinder 311. After the rotating groove 312 reaches the position of the mounting hole 37, the guide groove 318 in the pressing block 317 contacts The positioning pin 316 at the top of the locking sleeve 32 guides and drives the positioning pin 316 at the top of the locking sleeve 32 through the guide groove 318, driving the locking sleeve 32 to deflect at a certain angle, and the locking bead 38 is clamped into the rotating groove 312 through the inner wall of the locking sleeve 32 to complete the locking of the rotating drum 311. At this time, only the horizontal rotation degree of the rotating drum 311 is retained, and when there is no external force driving the locking sleeve 32 to rotate relative to the rotating sleeve 33, the locking sleeve 32 rotates synchronously with the rotating drum 311.

[0038] Apply external force to the locking sleeve 32 and rotate it in the opposite direction to the rotating sleeve 33 by a certain angle, so that the positioning pin 316 at the top of the locking sleeve 32 is withdrawn from the guide groove 318, the unlocking groove 39 corresponds to the mounting hole 37, the locking bead 38 is released from the locking of the rotating groove 312, and the scanner 1 is pulled outward, so that the rotating drum 311 can be withdrawn from the rotating sleeve 33;

[0039] After the rotating drum 311 is locked, the scanner 1 is rotated to adjust the angle. A motor can be set on the bottom surface of the support base 21, and the shaft end of the motor is connected to the rotating drum 311, or a motor can be set in the scanner 1, and the shaft end of the motor is connected to the lower positioning plate 34.
