Referring to fig. 1-3, embodiments of the present application provide a power test clip for use as a terminal for temporary circuit connection in power testing that can be universally used for test conductors of various shapes and sizes. Specifically, the power test clip of an embodiment includes a clip body 10, a collet 20, and a fastening assembly 30. The clamp body 10 includes a first portion 11 and a second portion 12 hinged to each other, and the end of the first portion 11 and the end of the second portion 12 can move closer to or away from each other by using a lever principle. The chuck 20 is movably disposed at one end of the chuck body 10, and the chuck 20 can move toward or away from the chuck body 10. Specifically, the number of the clamping heads 20 is two, and the two clamping heads 20 are movably disposed at the end of the first portion 11 and the end of the second portion 12, respectively. The fastening assembly 30 connects the clip body 10 and the clip 20 for fixing the clip body 10 and the clip 20 to each other. Similarly, the number of the fastening assemblies 30 is also two, and the two fastening assemblies 30 are respectively arranged on the first portion 11 and the second portion 12 and are respectively connected with the corresponding chucks 20, so as to fix the relative positions of the chuck body 10 and the chucks 20.
The power test clamp is movably provided with a clamping head 20 at the end of the clamp body 10, and the maximum opening distance of the power test clamp is larger as the length of the power test clamp is longer. By moving the collet 20 closer to or farther from the collet body 10, the overall length of the power test clamp is varied, and the maximum opening distance of the power test clamp can be varied. Therefore, the electric test clamp can adjust the clamp body 10 and the chuck 20 to a proper relative position, and then fix the chuck 20 and the clamp body 10 at the position through the fastening assembly 30, so that the electric test clamp has a proper maximum opening distance, and further the electric test clamp can be suitable for test conductors with different shapes, structures and sizes, and the universality of the electric test clamp is improved.
Further, referring to fig. 1, the clamp body 10 is provided with a slide rail 111 extending along the length direction thereof, the collet 20 includes a body 21 and a telescopic portion 22 extending along the length direction of the body 21, and the telescopic portion 22 is embedded in the slide rail 111 and slidably engaged with the slide rail 111, so that the collet 20 can be telescopic along the length direction relative to the clamp body 10, thereby changing the length of the power test clamp and further changing the maximum opening distance of the power test clamp. Specifically, the longer the length of the telescopic portion 22 extending out of the slide rail 111 is, the longer the length of the power test clip is, and the larger the maximum opening distance of the power test clip is. Conversely, the longer the length of the extension part 22 inserted into the slide rail 111, the shorter the length of the power test clip, and the smaller the maximum opening distance of the power test clip. Further, the retractable portion 22 and the body 21 are integrally formed, for example, the retractable portion 22 can be formed by folding a portion of the body 21 at a right angle, so that a detent is formed between the body 21 and the retractable portion 22, and the detent is used for being engaged with the notch of the slide rail 111, so as to prevent the body 21 from being embedded into the slide rail 111.
Further, referring to fig. 1 and 3, the clip body 10 is provided with a first blocking member 131 and a second blocking member 131 opposite to each other, and the first blocking member 131 and the second blocking member 131 define the slide rail 111, that is, the first blocking member 131 and the second blocking member 131 jointly form the square slide rail 111. Further, the first stopper 131 and the second stopper 131 are respectively abutted against both sides of the telescopic part 22, thereby guiding the sliding movement of the telescopic part 22 and preventing the cartridge 20 from coming off from the slide rail 111.

The first spacer 32 is connected to the connecting member 31 and abuts against one side of the clip body 10. The second washer 33 is connected to the connecting member 31 and abuts the other side of the clip body 10.
Referring to fig. 1, in one embodiment, an elastic member 34 is sleeved on the connecting member 31, and one end of the elastic member 34 is connected to the first gasket 32, so that the first gasket 32 can press the clamp body 10 under the elastic force of the elastic member 34.

Furthermore, one end of the connecting piece 31 close to the second gasket 33 is provided with a bent portion 15, and the bent portion 15 abuts against the second gasket 33, so as to prevent the connecting piece 31 from falling off, and indirectly enable the second gasket 33 to press the clamp body 10 under the pulling force of the elastic piece 34.
In another embodiment, the elastic member 34 is sleeved on the connecting member 31, and one end of the elastic member 34 is connected to the second pad 33, so that the second pad 33 can press the clamp body 10 under the elastic force of the elastic member 34. Further, the connecting piece 31 is close to the one end of second gasket 33 still is equipped with spacing gasket 35 to spacing gasket 35 and second gasket 33 interval set up, and elastic component 34 sets up between second gasket 33 and spacing gasket 35, and second gasket 33 and spacing gasket 35 are connected respectively to the both ends of elastic component 34, and spacing gasket 35 is used for increasing the tip area of connecting piece 31, prevents that elastic component 34 from deviating from. Furthermore, one end of the connecting member 31 close to the first gasket 32 is provided with a bent portion 15, and the bent portion 15 abuts against the first gasket 32, so as to prevent the connecting member 31 from falling off, and indirectly enable the first gasket 32 to press the clamp body 10 under the pulling force of the elastic member 34.
Through the elastic force effect of the elastic piece 34, the first gasket 32 and the second gasket 33 can clamp the clamp body 10, the friction force between the first gasket 32 and the clamp body 10 and between the second gasket 33 and the clamp body 10 are increased, so that the moving resistance of the connecting piece 31 is increased, the connecting piece 31 cannot move easily, the telescopic movement of the chuck 20 has certain resistance, and the relative position of the chuck 20 and the clamp body 10 can be conveniently fixed after the telescopic size of the chuck 20 is adjusted according to requirements. Specifically, when the telescopic dimension of the chuck 20 needs to be adjusted, the elastic member 34 can be contracted, so that the first gasket 32 or the second gasket 33 is separated from the clamp body 10, and at this time, the friction force between the fastening assembly 30 and the clamp body 10 is reduced, and the fastening assembly 30 can move freely in the limiting groove 112, so that the chuck 20 can perform telescopic motion relative to the clamp body 10.
It should be noted that the number of the elastic members 34 is not limited to one, and in one embodiment, the elastic members 34 are connected to both the first pad 32 and the second pad 33. Correspondingly, the number of the limiting washers 35 is also two, and the two limiting washers 35 are respectively arranged at two ends of the connecting member 31 to prevent the two elastic members 34 from being released from the connecting member 31. The first gasket 32 and the second gasket 33 can further clamp the clamp body 10 under the action of the elastic members 34 on both sides of the clamp body 10, so that the fastening stability of the fastening assembly 30 to the clamp body 10 and the chuck 20 is improved.
