Detailed Description

The invention is described in detail below with reference to the figures and the embodiments.

A clamp suitable for a button battery is composed of an upper shell, a lower shell, an upper conductive assembly and a lower conductive assembly which are insulated.

The opposite side surfaces of the lower shell of the upper shell are respectively provided with a first concave cavity and a second concave cavity, and the lower shell of the upper shell is in threaded connection with the external threads through internal threads; an upper conductive component is arranged in the first concave cavity, and a lower conductive component is arranged in the second concave cavity.

The upper conductive assembly consists of a pressure plate and a first conductive rod which are coaxial, the section of the first conductive rod is T-shaped and comprises an upper transverse rod and an upper longitudinal rod; the upper cross rod is matched with the first groove in the bottom surface of the pressure plate, and a third spring group is arranged between the cross rod and the pressure plate; go up the vertical pole and see through pressure disk and epitheca in proper order, be equipped with first spring assembly between pressure disk and the epitheca.

The lower conducting component consists of an upper disc, a lower disc and a second conducting rod which are coaxial. The upper plate and the lower plate are jointed to form a three-jaw chuck structure: the binding surface of the upper disc and the lower disc is provided with a slide bar component which comprises a plurality of circular slide bars arranged on the bottom surface of the upper disc and a circular clamping groove arranged on the top surface of the lower disc; along the radial direction, the upper disc is provided with a plurality of linear clamping grooves internally provided with clamping jaws, and the bottoms of the clamping jaws are provided with threads which are meshed with the threads on the top surface of the lower disc. The outer side of the upper disc is provided with a plurality of pairs of sliding blocks which are matched with sliding grooves longitudinally arranged on the inner wall of the lower casing.

The cross section of the second conducting rod is T-shaped and comprises a lower cross rod and a lower longitudinal rod: the lower cross rod is matched with the second groove on the top surface of the upper disc, and a second spring set is arranged between the bottom of the lower cross rod and the second groove. The lower longitudinal rod penetrates through the upper disc, the lower disc and the lower casing in sequence through the through hole, and outside the ring of the through hole, a threaded column which extends out of the lower casing and is in threaded connection with the lower casing is arranged at the bottom of the lower disc.

When in use, the utility model is used,

placing the button battery on the top surface of the upper disc, rotating the threaded column from the bottom of the lower shell, and linking the lower disc to rotate; the upper disc is in a static state relative to the lower disc due to the limitation of the sliding block and the sliding groove along the circumferential direction; namely, the sliding rods are relatively fixed, the lower disc rotates along the circular clamping groove, the rotating lower disc moves along the linear clamping groove through the thread linkage clamping jaws on the disc surface, namely, a plurality of clamping jaws synchronously move towards the center of a circle to fix the button cell.

When the lower disc rotates, the threaded column moves downwards relative to the lower shell, namely the lower disc is linked to move downwards; due to the fact that the sliding rod is longitudinally clamped with the circular clamping groove, the lower disc is linked with the upper disc to move downwards along the sliding groove, the button battery moves downwards, and the button battery is placed into the second groove.

With epitheca and inferior valve threaded connection, along with the rotation of screw thread for the pressure disk laminates the battery upper surface gradually, and first spring assembly, second spring assembly, third spring assembly make the state of first conducting rod and the laminating of second conducting rod more hug closely.

The detection and test of the button cell can be carried out through the upper vertical rod and the lower vertical rod which are led out.

After detection and test are finished, the upper shell is rotated reversely, and the upper pressure is released; and then the threaded column is rotated reversely, so that the three-jaw chuck is released and fixed while the button battery is lifted out of the second concave cavity.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
