Abstract
Abstract An instrument support elbow includes a seat body. A coupling seat upward extends from one side of the seat body for rotatably coupling with a rotary block. The rotary block is formed with a radial through hole for a support rod to extend therethrough. The rotary block is formed with a cavity perpendicularly intersecting the through hole. A fixing member passes through the cavity to the through hole. The fixing member is formed with a ring hole corresponding to the through hole, whereby the support rod extends through the ring hole and the through hole. A turning member extending out of the rotary block serves to drive the fixing member to move along the radius of the support rod.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
199 words
An instrument support elbow comprising a seat body, a coupling seat upward extending from one side of the seat body for rotatably coupling with a rotary block, a coupling face of the rotary block facing the coupling seat being formed with an axial thread hole, the coupling faces of the rotary block and the coupling seat being formed with cooperative toothed sections for locating the rotary block, a bolt extending through the coupling seat and being screwed in the thread hole of the rotary block for fixing the rotary block, the rotary block being formed with a radial through hole for a support rod to extend therethrough, said instrument support elbow being characterized in that the rotary block is formed with a cavity perpendicularly intersecting the through hole, the support rod extending through the through hole passing through the cavity, a fixing member being disposed in the cavity, the fixing member being formed with a ring hole corresponding to the through hole, whereby the support rod extends through the ring hole and the through hole, a turning member extending out of the rotary block serving to drive the fixing member to move along the radius of the support rod.
Claim 2
Dependent Claim
199 words
An instrument support elbow comprising a seat body, a coupling seat upward extending from one side of the seat body for rotatably coupling with a rotary block, a coupling face of the rotary block facing the coupling seat being formed with an axial thread hole, the coupling faces of the rotary block and the coupling seat being formed with cooperative toothed sections for locating the rotary block, a bolt extending through the coupling seat and being screwed in the thread hole of the rotary block for fixing the rotary block, the rotary block being formed with a radial through hole for a support rod to extend therethrough, said instrument support elbow being characterized in that the rotary block is formed with a cavity perpendicularly intersecting the through hole, the support rod extending through the through hole passing through the cavity, a fixing member being disposed in the cavity, the fixing member being formed with a ring hole corresponding to the through hole, whereby the support rod extends through the ring hole and the through hole, a turning member extending out of the rotary block serving to drive the fixing member to move along the radius of the support rod.
Claim 3
Dependent Claim
38 words
The instrument support elbow as claimed in claim 1 , wherein the cavity is formed on one side of the thread hole of the rotary block facing the coupling seat for disposing the fixing member in the cavity.
Claim 4
Dependent Claim
56 words
The instrument support elbow as claimed in claim 1 , wherein the fixing member is a retainer ring formed with a ring hole corresponding to the through hole, the turning member being a threaded section extending from the retainer ring, the threaded section extending out of the rotary block and being locked with a rotary switch.
Claim 5
Dependent Claim
18 words
The instrument support elbow as claimed in claim 3 , wherein the rotary switch is a butterfly nut.
Claim 6
Dependent Claim
26 words
The instrument support elbow as claimed in claim 3 , wherein the circumference of the ring hole of the retainer ring is formed with multiple teeth.
