The base 50 is inverted T. The base 50 is pivotally connected to the connecting rod 52 and the long rod 54 , and the operating rod 58 is pivotally connected to the connecting rod 52 and the long rod 54 to form a link mechanism. The connecting rod mechanism mainly moves the operating rod 58 and the long rod 54 together, and after the operator pulls the operating rod 58, the connecting rod 52 drives the long rod 54 to push the long rod 54 with the rod The piece 56 is moved toward a workpiece 3 (as shown in Fig. 4), and the pushing member 56 is pressed against the workpiece 3 for positioning purposes. The structure described above is the same as the conventional quick clamp, and its contents are not described in detail herein.

The main improvement of the present invention is the pressure adjusting device 1. Referring to Figures 2 to 3, the pressure adjusting device 1 comprises a body 10, a movable member 20, a fixing member 30 and an elastic member 40.

The body 10 has a hollow circular shape, and the body 10 has a first opening 12 at one end and a second opening 14 at the other end. In this embodiment, a first stopper 13 is disposed at one end of the body 10, the first opening 12 is disposed at a center of the first stopper 13 , and a second stopper 15 is disposed at the other end. The second opening 14 is provided in the center of the second stopping member 15, and the second opening 14 is a screw hole.

The movable member 20 is movably coupled to one end of the body 10. In this embodiment, the movable member 20 has a first stopper 22 at one end thereof, the first stopper 22 has a circular outer shape and an outer diameter larger than the diameter of the first opening 12, and the movable member 20 passes through the The first opening 12 is such that the first block 22 is located in the body 10. The first block 22 protrudes outwardly from a center of a side surface of the second stopper 15 to form a first connecting block 24, and the first connecting block 24 has a cylindrical shape. The movable member 20 is provided with a matching hole 26 in the axial direction at the other end of the first block 22, and one end of the pushing member 56 is inserted into the matching hole 26.

The fixing member 30 is fixed to the other end of the body 10 relative to the movable member 20. In this embodiment, the outer surface of the fixing member 30 has an externally threaded portion 32 and has a second stopper 34 at one end thereof. The fixing member 30 passes through the second opening 14 and the externally threaded portion The second opening 14 is screwed into the second opening 14 , and the second stopper 34 is disposed in the body 10 . The fixing member 30 is located at an end of the body 10 and is in contact with the quick clamp 2 . The fixing member 30 protrudes outwardly from the outer side of the second block 34 to form a second connecting block 36. The second connecting block 36 has a cylindrical shape. The second connecting block 36 is spaced apart from the first connecting block 24 by a predetermined distance and corresponds to each other.

In this embodiment, the elastic member 40 is a compression spring. The elastic member 40 is mounted on the body 10, and one end of the elastic member 40 is sleeved on the first connecting block 24 to abut the movable member 20, and the other end is sleeved on the second connecting block 36 to be fixed thereto. The piece 30 abuts. The first stopper 22 of the movable member 20 is normally abutted against the first stopper 13 , and the pushing member 56 is located at the most outward position and can be moved inward by force.

The pressure adjusting device 1 further includes an auxiliary fixing member 38 disposed on the fixing member 30 to firmly bond the fixing member 30 to the body 10. In this embodiment, the auxiliary fixing member 38 is a nut that is screwed with the external thread segment 32 of the fixing member 30 and abuts against the body 10 (or against the second stopper 15).

Referring to FIG. 4, when the user pulls the operating lever 58, the pressure adjusting device 1 is driven to move the workpiece 3 to press the pushing member 56 against the workpiece 3. Due to the action of the elastic member 40, the pressing position and the pressing force of the pushing member 56 can be adjusted. For example, when the quick clamp 2 holds a thick workpiece 3, as shown in FIG. 5, the pushing member 56 and the movable member 20 are moved by the workpiece 3 to move inside the body 10. And compressing the elastic member 40, automatically adjusting the pressing position and the pressing force of the pushing member 56 to match the size of the workpiece 3.

The operator can adjust the clamping pressure of the pressure adjusting device 1 according to the thickness of the workpiece 3. Specifically, moving the fixing member 30 toward the movable member 20 increases the deformation amount of the elastic member 40, and further The purpose of increasing the clamping pressure is achieved; conversely, if the clamping pressure of the pressure adjusting device 1 is to be reduced, the fixing member 30 only needs to be moved away from the movable member 20.

Referring to Figures 6 to 7, the pressure adjusting device 1 can be configured in various quick clamps. 6 shows that the pressure adjusting device 1 of the second embodiment is disposed in a vertical quick clamp 2'; and FIG. 7 shows that the pressure adjusting device 1 of the third embodiment is disposed in a push-pull quick clamp 2" Its function and function are the same as before, and will not be described here.

Referring to Fig. 8, a pressure adjusting device 1' according to a fourth embodiment of the present invention is disposed in an open latch type quick clamp 2"'. Referring to Figures 9 to 10, the main structure of the fourth embodiment is the same as that of the first embodiment, with the difference that the elastic member 40 of the fourth embodiment is a tension spring. The first connecting block 24 of the movable member 20 has an additional first hole 241, and the second connecting block 36 of the fixing member 30 has an additional second hole 361. One end of the elastic element 40 is inserted in the first The first hole 241 of the connecting block 24 is inserted into the second hole 361 of the second connecting block 36.

Therefore, after the operator pulls the operating lever 58, the elastic member 40 of the body 10 is changed from the originally unstretched state (as shown in FIG. 9) to the stretched state (as shown in FIG. 10). In this way, the pressure adjusting device 1' can maintain the positioning of the elastic member 40 by the movable member 20, so as to maintain the positioning of the workpiece 3 with the quick clamp 2"".
