More specifically, the bottom of the fixed shank 12 protrudes upwardly from a hook structure 124 , and the movable cymbal 21 defines a hanging hole 211 . The two ends of the elastic member 30 respectively hook the hook structure 124 and the hanging hole 211. Preferably, the elastic member 30 is a tension spring.

The limiting member 40 protrudes from the bottom 221 of the movable handle, and the limiting member 40 is in the The extending length of the first direction is smaller than the extending length of the two side portions 222 of the movable handle in the first direction. In other words, the limiting member 40 is located within the receiving slot 223 and does not protrude from the receiving slot 223. The limiting member 40 includes a blocking portion 41 defining an active space 42 between the blocking portion 41 and the bottom portion 221 of the movable handle. In the embodiment, the limiting member 40 is curved and looks like a hook. The limiting member 40 and the movable handle 22 are integrally formed. However, the shape of the limiting member 40 is not limited thereto, and is described first. Preferably, the release member 50 is located between the first end of the movable handle and the limiting member 40.

The release member 50 is pivotally disposed on the movable handle 22, and the release member 50 includes an abutting portion 51. The abutting portion 51 is located in the movable space 42 and selectively touches or moves away from the limiting member. The blocking portion 41, specifically, the releasing member 50 includes two pivoting pieces 52. The two pivoting pieces 52 integrally extend from both sides of the abutting portion 51 and define a pivoting space 53 with the abutting portion 51.

Preferably, the limiting member 40 is located between the protruding portion 71 and the first end 224 of the movable handle.

Referring to FIG. 1 and FIG. 3, when the clamp clamps an object (not shown), the movable handle 22 swings about the axis of the second pivot 82 toward the fixed handle 12, and the release member 50 The end portion 511 of the abutting portion is away from the blocking portion 41 of the limiting member, and then touches the bottom portion 221 of the movable handle, and then the user applies the force that can stretch the elastic member 30 to the movable handle 22, so that the The release member 50 is piled up by the bottom 221 of the movable handle. The release member 50 drives the linkage member 70 to swing toward the fixed handle 12. The movable handle 22 drives the movable jaw 21 around the axis of the first pivot 81. The direction of the fixed jaw 11 is swung until the imaginary line defined by the two ends of the connecting member 70 passes through the second pivot 82, and the object is clamped in the mouth. At this moment, the elastic member 30 is pulled. It has a certain force to extend to a certain length, but because the first and second pivot shafts 81 and 82 and the other end of the linkage member 70 form a triangular relationship, the elastic member 30 has no way to pull the movable jaw 21 and use When the hand is released from the forceps, the object is still clamped to the mouth.

Referring to FIG. 4, when the clamp is to release the object, the movable handle 22 is slightly swung a distance away from the fixed handle 12 about the axis of the second pivot 82, and the limit member is After the blocking portion 41 touches the end portion 511 of the abutting portion, the blocking portion 41 of the limiting member can move the releasing member 50. Referring to FIG. 5, at this time, the linking member 70 is wound around the fourth end. The axis of the pivot 84 is slightly oscillated, so that the imaginary line defined by the two ends of the connecting member 70 is away from the second pivot 82. The force of the elastic member 30 can be released to act to pull the movable 颚 21 Swinging away from the fixed jaw 11, the movable jaw 21 and the linkage member 70 are further affected by the force of the elastic member 30, and the movable handle 22 automatically continues to swing away from the fixed handle 12, When the end portion 511 of the abutting portion of the releasing member abuts against the blocking portion 41 of the limiting member, the movable handle 22 is restricted by the releasing member 50 and does not continue to move away from the fixing handle 12. Swinging, as shown in Fig. 6, whereby the size of the mouth is enlarged to make the object Creation of this release.

Therefore, when the user operates the clamp of the present invention, the effect of automatically releasing the object can be achieved without pressing the release member 50 by hand, which is labor-saving and convenient, and importantly, the limiting member 40 is convex. The bottom of the movable handle 221, therefore, the distance between the blocking portion 41 of the limiting member and the bottom 221 of the movable handle can be adjusted at the time of manufacture, and because the extending length of the limiting member 40 in the first direction is less than The extending length of the two side portions 222 of the movable handle in the first direction, in other words, the limiting member 40 is located in the receiving slot 223 and does not protrude from the receiving slot 223, thereby achieving at least the following effects :

1. The distance between the blocking portion 41 of the limiting member and the bottom 221 of the movable handle is shorter than the distance between the second limiting member of US, 6,626, 070 and the bottom of one of the movable handles. It should be noted that the blocking portion 41 of the limiting member The shorter the distance from the bottom 221 of the movable handle, the shorter the distance between the blocking portion 41 of the limiting member and the end portion 511 of the abutting portion of the releasing member, and the release member 50 can contact the limit more quickly. Bit 40.

2. During the process of pulling the movable handle 22 by the user, the force of the elastic member 30 can be released faster, so that the movable handle 22 can be automatically opened more quickly, and the object is faster to be clamped by the clamp. Release, the operation is more labor-saving and time-saving, similarly, this technical feature can also shorten the time when the release member 50 hits the bottom 221 of the movable handle when the user swings the movable handle 22 toward the fixed handle 12, thereby reducing the user. The time during which the movable handle 22 is moved in the direction of the fixed handle 12 is pulled.

3. The swing displacement distance of the movable handle 22 is reduced, and the degree of wear of the first, second, third, and fourth pivot shafts 81, 82, 83, 84 and the components connected thereto are indirectly reduced.

4. The limiting member 40 of the present invention does not affect the movement of the linking member at all, so the position of the limiting member 40 at the bottom 221 of the movable handle can be arbitrarily changed. When the limiting member 40 is closer to the first end 224 of the movable handle, The abutting portion 51 of the releasing member can achieve the foregoing functions without being made too long, so that the manufacturing cost of the releasing member 50 is much reduced compared with the prior art.
