Specifically, the drive assembly further includes a spring 370; one end of the second connecting arm 230 far away from the second rotating shaft 240 is provided with a through groove 380; the second connecting arm 230 axially slides through the through groove 380; the outer wall 120 of the second connecting arm 230 is provided with a protruding block 420; a sliding groove 390 extending along the axial direction of the through groove 380 is formed in the inner wall of the through groove 380; the protruding block 420 is matched with and embedded into the sliding chute 390; an annular groove 410 is formed in the inner wall of the through groove 380 at one end of the sliding groove 390, which is close to the second rotating shaft 240; annular groove 410 and through groove 380 share a central axis; the third connecting arm 430 can be rotated until the projection 420 is inserted into the annular groove 410; the spring 370 is disposed in the through groove 380, one end of the spring 370 is connected to the inner bottom wall of the through groove 380, and the other end of the spring 370 is connected to the second connecting arm 230; the spring force of the spring 370 causes the protruding block 420 to abut against the end wall of the chute 390 remote from the second rotation shaft 240.
The length of the third connecting arm 430 relative to the second connecting arm 230 can be adjusted through the above technical solution; specifically, normally, the protruding block 420 is inserted into the annular groove 410 (at this time, more of the third connecting arm 430 is inserted into the second connecting arm 230); when the mounting plate 110 needs to be mounted, the third connecting arm 430 is rotated to return the protruding block 420 to the sliding slot 390, and at this time, the third connecting arm 430 moves away from the second rotating shaft 240 under the elastic force of the spring 370, so that the third connecting arm 430 extends out relative to the second connecting arm 230, thus extending the overall length of the second connecting arm 230 and the third connecting arm 430, and being capable of manually driving the second rotating shaft 240 to rotate with more labor saving.
After the mounting plate 110 is mounted, the third connecting arm 430 may be manually compressed, such that the protruding block 420 is embedded into the annular groove 410, and then the third connecting arm 430 is rotated again, such that the protruding block 420 is abutted against the annular groove 410 again, so as to fix the position of the third connecting arm 430.
Specifically, a movable slot 440 is formed at one end of the third connecting arm 430 away from the second connecting arm 230; the fourth connecting arm 450 is rotatably disposed in the movable slot 440, and the fourth connecting arm 450 can be rotated to be embedded in the movable slot 440.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
