[0027] Example

[0028] The present embodiment provides a quick clamp, comprising two handles 1 with a gripping end and an inclined connecting end, and two jaws 2, the length of the jaws being greater than or equal to the diameter of the pipe clamp 4, the two jaws 2 being respectively connected to the connecting ends of the two handles 1, the connecting ends of the two handles 1 being cross-pivoted to form an X-shape, so that when the two handles 1 are away from each other, the two jaws 2 are away from each other, and the parts of the two handles 1 and the two jaws 2 that are away from each other are parallel to each other;

[0029] A torsion spring 3 is provided between the opposite sides of the two handles 1. The torsion spring 3 is located between the connecting ends of the two handles 1. The spring arms of the torsion spring 3 are respectively abutted against the adjacent handles 1. The two jaws 2 are designed to be hollow, and the pipe clamp 4 is inserted therein. The two handles and the two jaws form a scissors structure. The lever structure of the scissors can easily overcome the tension of the torsion spring. Compared with the clamping of the clamp, the operator does not need to tighten the bolts, which is easier and very convenient for temporary low-pressure and high-temperature pipe clamps 4.

[0030] A slot 5 capable of accommodating the spring arm of the torsion spring 3 is provided between the two opposite sides of the handles 1. The slot 5 is of hidden design and has a protective function.

[0031] The two jaws 2 are designed to be elliptical and flat, and the inclined surfaces contacting the pipe clamp 4 are processed into arc shapes to ensure that the jaws 2 are not locked with the inclined surfaces of the pipe clamp 4.

[0032] The width of the two jaws 2 is designed to be less than or equal to the diameter of the pipe clamp 4 at 1 / 2 of the inclined surface, ensuring continuous and enhanced clamping under the torsion spring 3.

[0033] When the utility model product is implemented:

[0034] During operation, the two jaws are opened by tightening the handle, and the two opened jaws are inserted into the pipe for clamping. When the handle is released, the jaws clamp the pipe under the torsion spring.

[0035] When the pipe clamp needs to be removed, the handle is gripped to compress the torsion spring, the two jaws are opened, and the opened jaws are moved out of the pipe clamp.

[0036] In summary, the product of the utility model adopts a handle lever structure to enable the operator to work easily; compared with the clamping of the clamp, the operator does not need to tighten the bolts, which is more relaxed.

[0037] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
