Detailed Description

The utility model is further illustrated below with reference to the figures and examples.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.

Example (b):

an adjustable single-double valve solvent universal clamping jaw is disclosed, referring to fig. 1-3, comprising a group of symmetrically arranged clamping jaw handles 1, wherein the front end of each clamping jaw handle 1 is provided with a clamping jaw 5; an arc-shaped groove 6 matched with the solvent bottle mouth is arranged on the clamping jaw 5, the clamping jaw 5 is assembled on the clamping jaw handle 1 in a sliding mode through a step screw 7, and a spring for resetting the clamping jaw 5 is arranged on the step screw 7.

A limiting nut 8 is arranged above the clamping jaw 5, the limiting nut 8 is assembled between the clamping jaw handle 1 and the clamping jaw 5 in a sliding mode through a limiting screw 9, and a vertical sliding groove with the same shape as the limiting nut 8 is formed in the clamping jaw 5.

Referring to fig. 1, the tail end of a clamping jaw handle 1 is provided with a tooth part 2 and a pin shaft hole 3, and the clamping jaw handle 1 is rotatably assembled through a pin shaft so that the tooth parts 2 are meshed with each other; the middle end of the clamping jaw handle 1 is provided with a tension spring 4 for resetting.

Referring to fig. 4, a limiting plate 10 for driving the two clamping jaw handles 1 to rotate around the pin shaft is arranged below the clamping jaw 5, and a limiting groove matched with the solvent bottle mouth double valve is arranged at the front end of the limiting plate 10.

Referring to fig. 4, a U-shaped groove with a front opening is arranged at the front end of the limiting plate 10, and the U-shaped groove is provided with a yielding groove matched with the solvent bottle mouth.

Referring to fig. 4, the upper end of the limiting plate 10 is provided with a sliding groove with the same direction as the limiting groove, and the clamping jaw supporting plate 11 is assembled in the sliding groove in a sliding manner. And a spring which enables the front end of the clamping jaw supporting plate 11 to be in elastic contact with a solvent bottle mouth is arranged at the rear end of the clamping jaw supporting plate 11.
