Description of the Invention: [Technical Field of the Invention] The present invention belongs to the field of hand tools, and more particularly to a forceps having two movable jaws. [Prior Art] During the work, some tools are often used to assist the smooth operation of the operation steps, so as to save time and effort, so that the work can be completed more quickly. As an auxiliary tool, hand tools, electric (or pneumatic) tools, etc., especially hand tools, are more convenient to carry one or two pieces in the workplace or in the home environment because of their portability and ease of operation. There are a wide variety of hand tools, and one of them is one of the sweeteners used for tanning. For example, the pliers shown in Fig. 7, generally referred to as chain fish tongs 80, are clamped to the workpiece by means of gripping edges 83 that face each other with the two jaws 81, 82, such as tubes, bolts or nuts. Among them, the jaw 81 is fixed at the end of the grip 84, and the other jaw 82 is coupled to the grip 84 by the pivot 85 and can be swung or rotated. By the spring 86 hooked to the grip 84, the jaw 82 is elastically and movablely opened, and as long as the urging lever 87 pivoted to the edge thereof is biased toward the grip 84, the two can be reduced. The corners of 81, 82 are further clamped between the two toothed gripping edges 83. Since the urging handle 87 drives the connecting rod 88 to operate synchronously, and the bolt 89 locks into the depth of the tail end of the grip 84, the displacement of the connecting rod 88 is restricted, thereby affecting the actuation of the urging handle 87, so that the two jaws 81, 82 are maintained. The state of the workpiece is clamped. Until the external force presses the follower 871 in the middle of the urging handle 87, the shackles of the two jaws 81, 82 are released. The _ clip 82 is opened to the maximum extent by the elastic force. The wrong figure of the brother 8 is not called the pipe wrench 90. It is formed on the top of the grip 91 with a clamping part 92 m... ^ ^ ^ This clamping part 92 is connected with a pivot 93 with a movable or rotating clamp 94' hangs the spring % on the grip 91 to keep the display clip 94 elastic and the movable opening. The 5 clamp 90 is moved to move the clamp 94 toward the (four) clamp portion. Clamping items, such as tubes

(2) Although the pipe wrench is swung or rotated to a large extent, the pipe wrench does not have the effectiveness of adjusting the force between the two cores by the fish clamp, and cannot be effectively applied to the workpiece other than the pipe fitting, and the use is limited or reduced. range. (The three-pliers of the movable type of money 'bounces to the maximum swing or the movement, the amplitude' causes the two jaws to expand to the maximum angle; the diameter of the workpiece can be different, and the small-diameter workpiece is encountered, open The pliers to the maximum angle can not smoothly apply force and accurately hold the workpiece, just remove the clamp and repeat the operation of the workpiece. Four k small to control the workpiece, the pliers may need to lock the bolt into the grip At the end, the adjustment time is quite cumbersome and slow, and it takes too much time to adjust the movement. 4 201041699 It can be known from these phenomena that the traditional clamp can only be applied to the use of certain workpieces, how to use two The advantages of the prior art are aggregated into one, and a new generation of clamps is produced, which is an urgent problem to be overcome. [Summary of the Invention] With the applicant's in-depth understanding of the prior art, after many studies and improvements, the clamp is proposed. The improved structure has one of the objects of the present invention: the two jaws are connected to the grip end of the clamp and can be flexibly rotated or swung, and the two movable jaws are quickly buckled. In addition to the parts, the holding force of the workpiece can be appropriately adjusted, and the advantages of the existing pipe wrench and the pliers are gathered in one of the pliers. One of the objects of the present invention is that one of the two jaws can be selectively selected. It is fixed and the other clamp can be clamped or pulled to perform the action of clamping or loosening the workpiece. In particular, one of the clamps has a contact member to provide a more stable workpiece. The support performance is maintained to prevent the clamp from being caught by the smooth surface of the workpiece. ^ In order to achieve the above objects, the present invention is a modified clamp structure characterized in that one end of a grip is locked into a bolt, and the other is The end is connected to a first clamp and a second clamp to swing or rotate on the grip, and selectively fixes the first clamp through a limiting mechanism disposed on the grip; the first clamp is recessed to form a grip a wall surface of the space, the wall mask having a joint portion rotatably coupled to the grip end, a gripping edge for holding the workpiece with the second clip, and an elastic contact member between the joint portion and the gripping edge; The second clamp has a clamping edge for holding the workpiece 5 201041699 with the first jaw, a spring hooked between the grip and the second jaw, and a force applying handle connected to the second jaw. The handle is rotatably coupled with a connecting rod and a follower in the middle portion, and the connecting rod has a linkage relationship with the bolt locked into the grip, and the interlocking relationship can be released by the driven member. According to the technical feature of the above, the clamp of the present invention The utility model comprises the following components: a grip, one end is locked with a bolt, and the other end is provided with a limiting mechanism; a first clamping clamp is recessed at the periphery to form a wall surface of the holding space, and one side of the wall surface is a tooth-shaped clamping edge, An elastic contact member is fixed adjacent to the clamping edge, and a connecting portion is formed on the wall surface of the touching member. The connecting portion of the first clamping member is connected to the end of the grip to be swingable or rotatable, and the periphery thereof is provided At least one matching limit mechanism interferes with the plunging portion of the first jaw swing; a second jaw that can be oscillated or rotated by being connected to the grip, the periphery having a tooth-shaped gripping edge that cooperates with the first jaw to hold the workpiece; Hook Between the grip and the second jaw; and a force applying handle, one end is connected to the second jaw, and a link and a follower are rotatably coupled at the intermediate portion, the link and the lock are locked The bolt has a linkage relationship, and the linkage relationship can be released by the follower. Therefore, the clamp of the present invention has the following advantages: (1) The range of the workpiece held by the lead of the present invention is determined by the angle between the two movable jaws, and is no longer a single one as in the prior art. The swing or the amplitude of the clip is determined. (2) gripping the force applying handle of the clamp of the present invention, so that the second clamp is fixed, and can be used as a pipe wrench, and the first clamp is moved to hold the pipe; in particular, the clamp of the invention has two clamps The tension between the 6 and 201041699 forces can be adjusted by bolts. In addition to the pipe fittings, it can be applied to other non-tubular workpieces, and the range of use is relatively expanded. (3) The first clamp is temporarily fixed on the grip by the limiting mechanism, which can be used as a pliers. The second clamp is used to hold the workpiece by the force of the handle; in particular, the flexible use of the pipe wrench and the pliers The advantage is that the first clamp can be released at any time without being restricted by the separate movable clamp, and the clamp relationship is not often removed, and it is naturally unnecessary to repeatedly hold the workpiece. The gripping edges of the two jaws and the resilient contact members simultaneously contact the workpiece, making the gripping operation of the clamp of the present invention more stable. [Embodiment] Heretofore, the present invention has been summarized and understood in order to be able to go deep into the technical core of the present invention, and the following embodiments are proposed and described with reference to the drawings. However, the description or the illustrations are not intended to limit the scope of the invention, and the application of the invention to the same or equivalents, and the equivalents thereof First, please see a preferred embodiment of the present invention. As shown in FIGS. 1 and 2, the forceps 100 of the present embodiment includes a grip 10, a first jaw 20, a second jaw 30, and a hook between the grip 10 and the second jaw 30. The spring 40, a force applying handle 50, a contact member 60 and a limiting mechanism 70. The grip 10 has a U-shaped cross section, and its tail end is closed to lock a bolt 11, and a plurality of sets of corresponding perforations 12 and two symmetrical bidirectional holes 13 are provided at the head end. The two-way hole 13 extends through the longitudinal and lateral directions of the drawing surface of the 7 201041699 and holds the thick wall of the first end of the head, and presents an L shape.壁 壁 The wall surface 22 around the first jaw 20 is recessed to form a joint portion 23 and a gripping edge 24. The surface of the gripping edge 24 is a continuous tooth shape, and the wall portion 22 of the predetermined length is spaced apart from the joint portion 23 to The wall surface 22 of the first jaw 20 forms a holding space 21. In the present embodiment, the joint portion 23 refers to two thin walls 231 erected on the side of a flat surface 232 adjacent to the first cool wall 22 and above the parallel and symmetrical thin walls 231. Through the two holes 233, the holes 233 and the through holes 12 of the grip 10 are all oscillated or rotated by a coupling member 14 passing through the first jaw clamp 2 to the grip 1 (). Pivoted at the grip 1〇 and the first clip 2 people pass through the torsion spring 15, between the torsion springs 15 'one of the two arms 151 that extend, as shown in Fig. 3, touches a short rod 16, the other arm The 151 abuts against the plane μ) of the joint portion 23, and the torsion spring 15 accumulates the torsion force required for the first jaw 20 to return to the original state as the first jaw 20 swings or rotates. From the second and third figures, it is known that the wall 22 of the first money 2 located between the joints 24 is attached to the contact of the contact member. The contact member 6〇 of the present embodiment includes a contraction magazine 62, and a molding portion formed on the wall surface 22 of the first clip 20.

The corner of the second clamp 30 is rotatably coupled to the top end of the urging handle 50, and a link 51 and a follower 52 are framed in the middle portion of the urging handle 50. The tail portion of the link 51 has an interlocking relationship with the end portion of the bolt 11 of the lock handle 10, and the interlocking relationship can be removed by the follower 52. 〇 It can be understood from the above description that the present embodiment has various options in the use mode: For example, the third to fifth figures show that the first clamp 20 of the grip 10 is temporarily held. In the drawing, the T-shaped rod 71 of the limiting mechanism 70 is inserted into the insertion portion 73 of the first jaw 20 with the transverse shaft 711, so that the first jaw 20 is fixed and cannot swing or rotate on the grip 10 until T The rod 71 no longer interferes with the first jaw 20 . At this moment, the clamp 100 will open the second jaw 20 to the maximum width of 0 degrees due to the spring 40, and the second jaw 30 is rotated by the force applying handle 50 to rotate the first jaw 20 to make the first jaw. The clip 20 and the second jaw 30 are capable of holding the workpiece A. During the holding of the workpiece A, in addition to being clamped in the holding space 21 by the holding edges 24, 31 of the first jaw 20 and the second jaw 30, the sheet 61 of the contact member 60 also contacts the surface of the tubular workpiece A. . In other words, the gripper 100 performs the three-point support of the workpiece A, and the workpiece A can be clamped more securely than the prior art to facilitate the smoothing of the twisting step. It is worth noting that the clamp 100 twists the workpiece A for one-way rotation 201041699, and the workpiece A does not follow the reverse rotation of the clamp 1〇(). Since the workpiece A presses the sheet 61 back to the trap portion 63, t is slightly separated from the first clip 2G and the second (four) 3G without contacting the grip 31, so that the sweetener 1 is smoothly transferred to a certain reverse direction. At the angle, the workpiece A naturally does not follow the jaws. When the jaw 100 is again rotated in one direction, the compression spring 62 abuts against the sheet 61 and waits for the workpiece A to be pushed back and contacts the two gripping edges 24, 31, causing the workpiece A to perform a one-dimensional one-way rotation.钳 The clamp 100 of the present embodiment does not need to release the clamp relationship even if the first clamp 20 is not released, and it is not necessary to repeatedly hold the workpiece, so that the flexible operation is superior to the prior art. Fig. 6 is another use aspect, that is, the first jaw 20 pivotally attached to the jaw 100, and the second jaw 30 is flexibly oscillated. In the drawing, the τ-shaped rod 71 of the limiting mechanism 70 follows the bidirectional hole 13 to the horizontal direction, so that the insertion portion 73 of the first clip 20 loses the interference of the 杆-shaped rod 71, and can be re-arranged on the grip 1 〇 Swing or turn.施 The force applying handle 50 in the drawing surface is evenly biased toward the gripper 1 , so that the second jaw 30 cannot be opened outwards, and the user can still apply the one of the first clamping members 20 to the outer clamping portion 25 Pressing, the first jaw 2〇 is displaced between the dotted line and the line, and the workpiece A is held for twisting. Even if the pulling portion 25 is not pressed, the user can grip the force applying handle 50 and the grip 1〇' to use the pliers 10〇 as a pipe wrench, and the first display clip 20 can be used to hold the workpiece A. The maximum amplitude of the first jaw 20 and the second jaw 30 that are flexibly oscillated determines the maximum angle of the jaw 1 ,, and unlike the prior art, the amplitude or rotation of the single jaw can only be used.
