Abstract
The invention relates to a parallel clamp, and belongs to the technical field of clamps. The defects that according to an existing ordinary clamp, the clamping stability effect is very poor, adaptability is weak and an object is prone to being damaged are overcome. The parallel clamp comprises a first handle, a second handle, a first clamp arm, a second clamp arm, bolts, nuts, bolt heads and rotating shafts. The first handle is connected with the second handle through the rotating shaft. The first handle and the second clamp arm are connected through the rotating shaft. The second handle and the first clamp arm are connected through the rotating shaft. The first clamp arm and the second clamp arm are connected through the rotating shaft. The parallel clamp is characterized in that two threaded through holes are formed in the parts, far away from the connected ends, of the first clamp arm and the second clamp arm respectively, the bolts are arranged in the threaded through holes respectively, the bolt heads of the bolts are arranged in a clamp opening formed by the first clamp arm and the second clamp arm, and screws on the bolts penetrate through the threaded through holes to be connected with the nuts. The parallel clamp is good in clamping stability effect and can adapt to clamping objects of different thicknesses and can also clamp objects with the thin walls or the weak pressed capability.
Description
Technical field
The present invention relates to tongs technology field, particularly relate to a kind of parallel clamp.
Background technology
At present, common pliers only has a turning cylinder and two critical pieces, its jaw both sides are generally uneven, so when clamping objects such as cuboid, cylinder, spheroids, due to the factor that contact area is little, object receiving force is uneven, cause clamping stablizing effect very poor, even cannot realize the clamping to described object; Common pliers jaw when opened with certain angle can be made to be in the state of being parallel to each other by design, but it only can clamp, and cannot adapt to the clamping of the object of different-thickness to the rectangle object of fixed thickness.
The holding capability of common pliers is subject to the angle restriction that pliers opens, and ensure clamping effect, the angle that pliers opens is larger, larger power will be applied to held object, therefore, when clamping thin-walled or the weak object of compression capability, easily destroy by the object clamped.
Summary of the invention
The object of the present invention is to provide a kind of parallel clamp, the clamping stablizing effect existing common pliers existing for of solution described in background technology is very poor, adaptability is weak and the shortcoming of destructible object.
Technical scheme of the present invention is:
A kind of parallel clamp, comprise first handle, second handle, it is the first tong arm, second tong arm, bolt, nut, bolt head and rotating shaft, first handle and second handle, first handle and the second tong arm, second handle and the first tong arm, all connect respectively by rotating shaft between first tong arm and the second tong arm, it is characterized in that: on the first tong arm and the second tong arm, be respectively equipped with a tapped through hole away from interconnective one end, a bolt is provided with in tapped through hole, the bolt head of bolt is in the jaw be made up of the first tong arm and the second tong arm, screw rod on bolt is connected with nut through tapped through hole.
The axis of the tapped through hole on the first described tong arm overlaps with the axis of the tapped through hole on the second tong arm and the diameter of tapped through hole is identical.
Screw rod on described bolt is provided with screw thread, and the screw thread on screw rod and the screw thread on tapped through hole cooperatively interact, and the straight warp of screw rod is identical with the diameter of tapped through hole.
The difference of the thickness of described threaded screw fasteners head is divided into 2mm, 3mm, 4mm and 5mm tetra-groups, often organizes two.
Screw rod between described bolt head and the first tong arm, the second tong arm is also provided with pad.
Described pad is divided into different more than two of thickness, often organizes two.
The thickness of described pad is 0.1mm to 10mm.
Beneficial effect of the present invention is: parallel clamp of the present invention clamping stablizing effect is good, can adapt to the clamping of the object of different-thickness, can also clamp thin-walled or the weak object of compression capability.
Accompanying drawing explanation
Fig. 1 is the front view of parallel clips;
Fig. 2 is the left view of parallel clips.
Wherein, 1 is first handle, and 2 is second handle, and 3 is the first tong arm, and 4 is the second tong arm, and 5 is bolt, and 6 is nut, and 7 is bolt head, and 8,9,10,11 is rotating shaft.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technical scheme.
In FIG, a kind of parallel clamp, comprises first handle 1, second handle 2, first tong arm 3, second tong arm 4, bolt 5, nut 6, bolt head 7 and rotating shaft 8,9,10,11.Wherein, first handle 1 is connected by rotating shaft 10 with second handle 2, and first handle 1 and second handle 2 can rotate around rotating shaft 10 mutually.First handle 1 is connected with the second tong arm 4 by rotating shaft 11, and second handle 2 is connected with the first tong arm 3 by rotating shaft 9, and first handle 1 and the second tong arm 4 and second handle 2 and the first tong arm 3 can rotate around interconnective rotating shaft 11,9.One end between the first tong arm 3 and the second tong arm 4 is connected by rotating shaft 8, and the first tong arm 3 and the second tong arm 4 can rotate around rotating shaft 8 equally mutually.First tong arm 3 and the second tong arm 4 are respectively equipped with a tapped through hole away from interconnective one end, and the first tong arm 3 overlaps with the axis of the tapped through hole on the second tong arm 4 and the diameter of tapped through hole is identical.In tapped through hole, be provided with a bolt 5, the screw rod on bolt 5 is provided with screw thread, and the screw thread on screw rod and the screw thread on tapped through hole cooperatively interact, and the straight warp of screw rod is identical with the diameter of tapped through hole.The bolt head 7 of bolt 5 is in the jaw be made up of the first tong arm 3 and the second tong arm 4, and the screw rod on bolt 5 is connected with nut 6 through tapped through hole.
In order to realize parallel clamp, the object of different-thickness can both parallelly be clamped, bolt 5 has four groups, often organize two, be divided into 2mm, 3mm, 4mm and 5mm tetra-groups by the difference of the thickness of bolt head 7, the screw rod between bolt head 7 and the first tong arm 3, second tong arm 4 is also provided with pad.Pad is divided into different more than two of thickness, and often organize two, the thickness of pad is 0.1mm to 10mm.By the pad of installation different-thickness, different with use bolt head 7 thickness from bolt 5, realizes parallel clamp and can both parallelly clamp the object of different-thickness.Time parallel clamping is clamping, the position of jaw clamping is parallel to each other; the stable holding to gripped object can be realized; minimum chucking power can also be used to realize stable holding, when clamping thin-walled or the weak object of compression capability like this, the shape of gripped object can be protected.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
