[0026] It is worth mentioning that threaded holes 12 are provided on both sides of both ends of the surge protector 1, and wiring terminals 13 are provided in the wiring holes 11. The threaded holes 12 are used in conjunction with fastening screws 24, and the wiring terminals 13 electrically connect the wires to the surge protector 1;

[0027] It is worth mentioning that the pressure plate 32 is provided with extensions 23 on both sides, which abut against the two sides of the housing of the surge protector 1. The extensions 23 are provided with fastening screws 24, which are threadedly connected to the threaded holes 12, so that the extensions 23 are connected and fixed to the surge protector 1. A support portion 25 is provided on one side of the pressure plate 32, and the support portion 25 is provided with a through hole 26. The pressure plate 3 rotates around the through hole 26 as the axis.

[0028] It is worth mentioning that the pressing plate 3 is provided with a buckle groove 35 near the elastic portion 31, which facilitates the user's finger to be inserted between the pressing plate 3 and the pressure plate 32;

[0029] It is worth mentioning that the pressing plate 3 is provided with a protrusion 36 , which is hinged to the through hole 26 ;

[0030] It is worth mentioning that the shape of the resisting portion 4 is set to be an arc, which fits the shape of the wire and increases the contact area and friction between the pressure plate 3, the pressure plate 32 and the wire.

[0031] The operating principle of the present invention is now described as follows:

[0032] When the exposed part of the wire is electrically connected to the terminal 13, the insulation layer of the wire is placed on the abutment portion 4 of the pressure plate 32, and the pressure plate 3 is rotated to insert the elastic portion 31 into the through hole 21. When the fixing block 32 enters the through hole 21, it is squeezed by it, causing the elastic portion 31 to move in a direction away from the fixing groove 22 and store energy. Until the fixing block 32 coincides with the fixing groove 22, the elastic portion 31 releases the elastic force to embed the fixing block 32 into the fixing groove 22, so that the pressure plate 3 and the pressure plate 32 are connected and fixed. The downward force is continuously applied to the pressure plate 3, and the fixing block 32 is separated from the fixing groove 22 through the first inclined surface 33 and moves to the next fixing groove 22, thereby fixing the fixing block 32 to the fixing groove 22 at different positions according to the diameter of the wire, and forming a force to clamp the wire.

[0033] When the force clamping the wire needs to be released, an upward force is applied to the compression plate, and the protrusion is disengaged from the fixing groove 22 via the second inclined surface 34 .

[0034] The above design solution can enable the product to achieve the advantages of improved wiring stability and convenient operation.

[0035] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
