Pincers

Abstract

A pair of pincers comprises a fixed pincer handle, a movable pincer handle, a return part, a clamping mouth adjusting unit and a release part. The movable pincer handle comprises a movable clamping section and a movable holding section pivotally connected with the fixed pincer handle. The return part is arranged between the fixed pincer handle and the movable pincer handle. The clamping mouth adjusting unit comprises a connecting piece, an adjusting piece and a screw rod piece. The connecting piece is pivotally arranged on the movable holding section, the screw rod piece is pivotally arranged on the fixed pincer handle, one end part of the adjusting piece is rotationally arranged on the connecting piece, and the other end part of the adjusting piece is used for allowing the screw rod piece to be arranged in a screwing manner. The release part is pivotally arranged in the movable holding section. Therefore, by rotating the adjusting piece, the screw rod piece can be screwed out of or in the adjusting piece, so that the movable clamping section and the movable holding section of the movable pincer handle are pulled to adjust the size of the clamping mouth of the pair of pincers.

Description

technical field [0001] The invention relates to a clamp, in particular to a clamp with an easy-to-assemble clamping jaw adjustment structure. Background technique [0002] see figure 1 , an existing clamp 1 includes a fixed clamp handle 11 , a movable clamp handle 12 , a spring member 13 , a jaw adjustment unit 14 , and a release member 15 . The fixed jaw handle 11 includes a fixed jaw segment 111 and a fixed grip segment 112 . The movable jaw handle 12 is pivotally connected to the fixed jaw handle 11 and includes a movable jaw segment 121 and a movable gripping segment 122 pivotally connected to each other. The movable jaw segment 121 is pivotally connected to the fixed jaw segment 111 , and can form a jaw 10 with a jaw angle θ with the fixed jaw segment 111 . Two opposite ends of the spring member 13 are respectively connected between the fixed holding section 112 adjacent to the fixed jaw section 111 and the two pivot points of the movable jaw section 121 . The jaw a...

Problems solved by technology

[0005] refer to image 3 When the adjustment member 143 is rotated so that the upper and lower screw members 141, 142 are unscrewed and separated from the adjustment member 143, and the user needs to align and combine the upper and lower screw members 141, 142 with the adjustment member 143, due to The upper and lower screw parts 141, 142 are pivotally connected to the movable holding section 122 and the fixed holding section 112 respectively, and the user's two hands must simultaneously move the non-fixed upper and lower screw parts 141, 142 and The adjustment member 143 is kept fixed and arranged along and parallel to a straight line, and the upper and lower screw members 141, 142 need to be respectively aligned with the two opposite openings of the screw groove 144 supported by the adjustment member 143 at the same time before starting Rotate the adjustment member 143 to simultaneously screw the upper and lower screw members 141, 142 into the screw groove 144 of the adjustment member 143, and the adjustment function can be achieved by screwing in at the same time, but the actual operation has the disadvantage of being difficult to assemble

[0006] Certainly, the user may also firstly connect the adjusting piece 143 with one of the upper and lower screw members 141, 142 in alignment and then screw in alignment with the other, and finally rotate the adjustment piece 143 to Screw the upper and lower screw members 141, 142 into the screw groove 144 of the adjustment member 143 at the same time. Although this method does not require simultaneous alignment of the two parts and is easier to assemble, it needs more steps to complete the upper and lower screw parts. The screw connection combination of the screw parts 141, 142 and the adjustment part 143, the important thing is that the screw connection process has the disadvantage that the adjustment function cannot be achieved synchronously

[0007] In addition, the adjustment member 143 may be dropped and lost because it can be rotated away from the upper and lower screw members 141, 142
