The first hinge shaft 6 and the second hinge shaft 7 have the same structure. The barrel support 5 includes a sleeve portion 51 for installing a supported component and a connecting rod portion 52 arranged at the bottom of the sleeve portion 51 and capable of being inserted into the groove opening 202, the connecting rod portion 52 is provided with a threaded rod area capable of matching with the locking nut 50, and the third hinge shaft 9 passes through the connecting rod portion 52.

[0031] When adjusting the inclination angle of the barrel bracket 5, first rotate the locking nut 50 to make it out of contact with the arc surface 200 of the second swing arm 20. At this time, the barrel bracket 5 can be rotated around the third hinge axis 9 to adjust the inclination angle. When the barrel bracket 5 is at a suitable angle, the locking nut 50 is rotated to press against the arc surface 200 of the second swing arm 20. The self-locking function of the thread is utilized to keep the locking nut 50 fixed after being squeezed onto the arc surface 200, thereby locking the barrel bracket 5 at this angle.

[0032] One end of the bolt rod 31 is a hexagonal head and is embedded in a slot 211 on one side of the first connecting portion 21 . The other end of the bolt rod 31 passes through the first connecting portion 21 .

[0035] The barrel support 5 is provided with a locking bolt 4 for locking and fixing the supported member. The locking bolt 4 includes a screw body 41, a push block 42 which is provided on one side of the head of the screw body 41 and can slide out, and a pin 43 which is provided on the screw body 41 and is used to limit the push block 42. By extending the push block 42 out of the screw body 41, the force arm can be increased.

[0036] A push block 42 that can slide out is provided at the head of the screw body 41. When the screw body 41 needs to be twisted and rotated, the push block 42 is pushed out of the screw body 41, thereby increasing the length of the rotating force arm of the screw body 41, thereby achieving a labor-saving effect. Secondly, a bayonet 43 is used to pass through the head of the screw body 41 to limit the push block 42, so as to prevent the push block 42 from falling off the screw body 41 during use, and to avoid the screw body 41 and the push block 42 from being separated during transportation and use. In addition, the bayonet 43 is used for limiting, so that the push block 42 can be easily replaced, and the practicality can be increased by replacing the push blocks 42 of different lengths.

[0037] A spring 44 for increasing friction is provided between the push block 42 and the screw body 41. A positioning hole 422 for positioning and installing the spring 44 is provided on the push block 42. One end of the spring 44 is located in the positioning hole 422, and the other end of the spring 44 is pressed against the inner wall of the screw body 41. The spring 44 is provided on one side of the push block 42 to contact and press against the inner wall of the screw body 41, thereby increasing the friction of relative sliding between the push block 42 and the screw body 41, so that the push block 42 always maintains a constant force during the pushing and pulling process, and the spring 44 can maintain the length of the push block 42 extending out of the screw body 41, so as to prevent the push block 42 from retracting during the rotation of the screw body 41 and affecting the use.

[0038] The head of the screw body 41 is provided with a plurality of protrusions 411 for applying force, and the push block 42 is located at one of the protrusions 411. By evenly providing a plurality of protrusions 411 around the head of the screw body 41, when the screw body 41 is rotated by hand, the protrusions 411 can greatly increase the convenience of applying force, making it easier to rotate the screw body 41.

[0039] The push block 42 is T-shaped, one end of which is inserted into the screw body 41, and the other end of which can be attached to the outer wall of the screw body 41 and evenly spaced from the convex portion 411 and distributed on the periphery of the screw body 41. The portion of the push block 42 extending out of the screw body 41 protrudes upward from the upper end surface of the screw body 41. The end of the push block 42 is arranged to protrude from the upper end surface of the screw body 41, so that the user can easily push the push block 42 out when using it.

[0040] The head of the screw body 41 is provided with a slide slot hole 412 for the push block 42 to be telescopically inserted, and the head of the screw body 41 is also provided with a limit hole 413 perpendicular to the slide slot hole 412 and used to install the bayonet 43, and the limit hole 413 extends to communicate with the slide slot hole 412; one side of the push block 42 is provided with a travel groove 421 for the bayonet 43 to be inserted and relatively slidable. The bayonet 43 is a kimm screw, and the maximum sliding stroke of the end of the bayonet 43 in the travel groove 421 is 5mm.

[0041] In the locking bolt 4, the spring 44 is installed on the push block 42 and inserted into the slide slot hole 412 of the screw body 41 together with the push block 42. Then the bayonet 43 is inserted from the limiting hole 413 to press into the stroke slot 421 of the push block 42 to realize the assembly of the push block 42 and the screw body 41. The limit of the push block 42 by the bayonet 43 allows the push block 42 to adjust the length of the screw body 41 within 5mm, and the friction between the push block 42 and the screw body 41 can be increased by the spring 44, so that the push block 42 maintains constant force during the push-pull process and can stay stably in a suitable position to prevent the push block 42 from sliding when the screw body 41 is twisted. When in use, the threaded portion of the screw body 41 is twisted into the corresponding threaded hole, and the push block 42 is pushed out of the slide slot hole 412 of the screw body 41, thereby extending the force arm length of the twisting screw body 41, thereby relatively increasing the force of twisting the screw body 41, and achieving a labor-saving effect.

After adjusting to the appropriate position, the handle 33 can be bent to the locking position. By adjusting in this way, it is only necessary to swing the handle 33 back and forth 90° to complete the locking and loosening of the relative rotation between the first swing arm 2 and the base 1, and the locking and loosening of the relative rotation between the second swing arm 20 and the first swing arm 2, which greatly improves the efficiency of the use and adjustment of the turret. In addition, when the handle 33 cannot be locked by turning it, the first thumb screw 34 can be removed and the handle 33 can be removed from the spline nut 32. After tightening the spline nut 32 to a suitable position, the handle 33 and the first thumb screw 34 can be re-installed in place, so that they can be locked and loosened by swinging the rotating rod handle 33 90° again.
