Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
It is shown referring to Figures 1 and 2, an embodiment of the column type limiting turn of the utility model, including bull stick 1 and two bullets
Property grip block 2, bull stick bottom are provided with swivel 3, and rotor surface is provided with spherical shape and turns face, and two resilient clamp blocks are held and mounted on
On swivel, spherical shape turns to be provided with spherical anchor ring 4 on the corresponding resilient clamp block in face, and above-mentioned spherical shape turns face and spherical anchor ring is matched
Close so that swivel, which does not fall out and turn, can do full movement, therefore effectively and the reliable rotation for realizing bull stick with
Swing effect；Wherein bull stick is not limited as connecting component, structure, and bull stick can connect external equipment；And two elastic clips
After holding block clamping swivel, due to elastic property so that swivel will not be clamped and can not rotate, by elastic allowance, swivel and bullet
Property grip block between it is there are frictional force and not stuck, can front and rear/left and right and horizontal axis while realizing and there is chucking power
The demand that direction rotates.Of course for ensureing that there is wider array of chucking power adjustable range, there is folder between two resilient clamp blocks
Hold gap.
Limited block 5 is set on the resilient clamp block below above-mentioned spherical anchor ring, swivel bottom is provided with angle rod 6,
When swivel does week movement, angle rod can be driven to rotate synchronously or swing, limited block is provided in angle rod motion range
Interior, therefore when angle rod rotates, block blocking can be limited, realize the effect of limiting rotating angle；It can certainly set
Into the effect for limiting rotation and swing simultaneously；Above-mentioned design can stop that swivel places 360 degree of rotations, limiting be played, so as to keep away
The possibility of connecting line rotation winding or rotation fracture is exempted from.
Two groups of elasticity locked assemblies 7 are provided between two resilient clamp blocks, are synchronized with the both ends in retained part
Limiting locking；Elastic locked assembly includes locking lever 8, and locking lever one end is provided with spacing head 9, and the other end is provided with threaded portion
10, locking lever passes through elastic part 11 and one of resilient clamp block to set, and locking lever passes through threaded portion and another elasticity
Grip block is threadedly coupled, therefore one of resilient clamp block can axially move on locking lever, and another bullet
Property grip block then with locking lever lock fix, wherein locking clamping after chucking power realized with elastic part and spacing head,
When needing to adjust chucking power, it is only necessary to the locking elasticity of locking lever is adjusted, it is easy to operate.
In one embodiment, one group of elasticity locked assembly is provided between two resilient clamp blocks, when quantity is set as one
During group, elastic locked assembly is arranged on wherein one end of retained part, and other end can set hinge or directly use
