## Abstract

A pressure adjusting device of a quick fixture includes a main member, a fixed member fixed to the main member, a movable member movably connected to the main member, and an elastic member received in the main member and having opposite end connected to the fixed member and the movable member to urge the movable member. With the pressure adjusting device the quick fixture can fix various workpieces with different thicknesses.

## Claims

### Claim 1

A pressure adjusting device of a quick fixture, comprising:
a main member having a first end and a second end at opposite ends thereof; each ends having an opening;
a fixed member fixed to the main member through the second end;
a movable member movably connected to the main member through the first end, wherein the movable member has a first stop block received in the main member,
an elastic member received in the main member and having opposite end connected to the fixed member and the movable member to urge the movable member;
wherein the main member has a first plug connected to the first end of the main member; the first plug is provided with a first opening, and the first stop block is larger than the first opening;
wherein the main member has a second plug connected to the second end of the main member; the second plug is provided with a second opening, and the second opening comprises a threaded hole, and the fixed member has a threaded section to be threaded with the second opening; and
an auxiliary holder located at the second end of the main member, wherein the auxiliary holder comprises a nut;
wherein the fixed member has a threaded section to be threaded with both the threaded hole of the second plug and the nut of the auxiliary holder in sequence, and the nut abuts against the second plug.

### Claim 2 (depends on 1)

The pressure adjusting device of the quick fixture of claim 1, wherein the main member has an inner threaded section on an interior side thereof, and fixed member has a first outer threaded section threaded with the inner threaded section of the main member.

### Claim 3 (depends on 1)

The pressure adjusting device of the quick fixture of claim 1, further comprising a plunger connected to the movable member.

### Claim 4 (depends on 1)

The pressure adjusting device of the quick fixture of claim 1, further comprising a plunger connected to the fixed member.

### Claim 5 (depends on 1)

The pressure adjusting device of the quick fixture of claim 1, wherein the movable member is provided with a first connector, and the fixed member is provided with a second connector; both the first connector and the second connector are received in the main member to be connected to the opposite ends of the elastic member respectively.

### Claim 6 (depends on 5)

The pressure adjusting device of the quick fixture of claim 5, wherein the elastic member is a compression spring urging the movable member to have the first stop block against the main member.

### Claim 7 (depends on 5)

The pressure adjusting device of the quick fixture of claim 5, wherein the elastic member is a tension spring with opposite ends hooked to a first bore on the first connector of the movable member and a second bore on the second connector of the fixed member.
