Claims

[Claims for Utility Model Registration] 1. A pair of clamp arms 1 and 2 formed from metal plate members so as to have an approximately L-shaped shape,
The longer leg members 1 ₁ , 2 ₁ are arranged so as to intersect with each other at approximately the center thereof, and a center pin 5 is inserted through the leg members 1 ₁ , 2 ₁ through the intersection thereof. The leg members 1 1 , 2 1 are connected to each other in a rotatable manner through the leg members 1 ₁ and 2 ₁ , and are formed from metal plate members so as to have an approximately “H”-shaped outline near each end of the leg members 1 1 and 2 1 . A pair of hinge plates 6, 7 are pivotally connected at one end thereof via each hinge pin 8, 9, and the vicinity of the other end of the hinge plates 6, 7 are overlapped with each other, and this overlap are pivotally connected to each other via a pin 11 near the open end of each leg portion ₁₀₁ of the shaft 10 formed from a metal rod member or the like so as to have a substantially U-shaped outline, and , the longer leg members 1 ₁ , 2 ₁ of the clamp arms 1 , 2 are interconnected near the ends by a lock spring 12 , thereby pulling the leg members 1 ₁ , 2 ₁ toward each other. Furthermore, there is a structure between the clamp arms 1 and 2 to prevent relative rotation about a center pin 5 that rotatably connects the intersection of the longer leg members 1 ₁ and 2 ₁ . A clamping device comprising a stopper means 20. 2. The stopper means 20 comprises a short length tubular stopper support member 22 fixed at its base to the longer leg member ₁₁ of one clamp arm 1, standing upright on its outer surface near the center pin 5. The leg member 1 is movably disposed inside the leg member 1.
₁ is the large diameter part ₂₁₂ , and the part near the end of the stopper support member 22 is the small diameter part 2.
The long leg members 1 ₁ and 2 1 of both clamp arms ₁ and ₂ are locked at the tip of the large diameter portion 21 ₂ of the stopper 21. With the spring 12 under tension, the stopper support member 22 and the stopper 2 are inserted into the through hole 25 formed in the longer leg member ₂₁ of the other clamp arm 2.
1. The clamp device according to claim 1, wherein the clamp device is inserted between the small diameter portion ₂₁ and the small diameter portion 21 of the Utility Model 1 by the action of a compression spring 24 arranged in a compressed state. 3 Large diameter portion 2 of stopper 21 of stopper means 20
₁ A request for registration of a utility model in which a slot 27 is made in the axial direction on the outer circumferential surface of the guide screw 26, the tip of which is inserted into the slot 27, and the guide screw 26 is screwed into the stopper support member 22 from the outside. The clamping device according to item 2. 4 Small diameter portion 2 of stopper 21 of stopper means 20
_1. The clamping device according to claim 2 or 3 of the utility model registration, which comprises a stopper support member 22 with a stopper support member 22 having a stopper support member 22, and a disk-shaped knob 23 attached to the stopper support member 22. 5 Large diameter portion 2 of stopper 21 of stopper means 20
1. The clamping device according to claim ₂ , 3 or 4, wherein the cutout portion ₂₁₄ is formed by diagonally cutting the end portion of 12. 6 Shorter leg member 1 of clamp arms 1 and _{2 2} , 2 ₂ have cam members 3 and 4 having a certain thickness, width and length, respectively, at the ends of the leg members 1 ₂ , 2 _{2 .} The clamp device according to any one of claims 1 to 5, which is fixed at right angles to the clamp device. 7. The clamping device according to claim 6, wherein each of the cam members 3 _{, 4} is formed into arcuate surfaces 31, 41 that protrude toward each other, and notches are formed on the arcuate surfaces 31, ₄₁ .
