Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4 and give, base 1 including the U-shaped, left and right sides is sliding connection respectively has the fixed frame 2 of fore-and-aft direction in the base 1, the rectangular channel 3 of left and right directions is seted up to base 1 downside, 3 internal rotations of rectangular channel are connected with and control axial guide arm 4, the coaxial fixedly connected with cylinder 5 respectively of the 4 left and right sides of guide arm, the opposite face of two cylinders 5 is the inclined plane of interior upper and lower, fixed frame 2 downside is equipped with the accessory plate 6 that stretches into rectangular channel 3 and Z shape, accessory plate 6 and base 1 sliding connection, two accessory plates 6 carry on the back the end and are equipped with axial push rod 7 about respectively, the back end of two push rod 7 contacts rather than the inclined plane of corresponding side cylinder 5 mutually, both sides are equipped with the elastic plate 8 of left and right directions respectively around in the base 1, a plurality of edges are seted up along left right direction equipartition and opening circuit groove 9 up to elastic plate 8 upside.

In order to facilitate the rotation of the cylinder 5 and the positioning of the rotation of the cylinder 5, a worm wheel 10 is coaxially arranged on the left side of the guide rod 4, a worm 11 meshed with the worm wheel 10 is rotatably connected in the rectangular groove 3, and the front end of the worm 11 penetrates through the base 1 and is coaxially provided with a knob.

In order to make the push rod 7 always contact with the inner end surface of the cylinder 5, the left and right sides in the rectangular groove 3 are respectively connected with the outer sides of the auxiliary plates 6 on the corresponding sides through left and right axial tension springs 12.

In order to facilitate better heat dissipation effect, the left side and the right side of the base 1 and the lower side of the base are provided with ventilation grooves 13.

In order to fix the base 1 conveniently, the left side and the right side of the base 1 are respectively provided with two positioning plates 14 which are uniformly distributed along the front-back direction, the positioning plates 14 are in threaded connection with positioning bolts 15 in the vertical axial direction, and the lower ends of the positioning bolts 15 penetrate through the positioning plates 14.

In order to facilitate the better protection of the exchange, the opposite faces of the two fixed frames 2 are respectively provided with rubber pads 16 in accordance with the shapes thereof.

When the circuit board is used, the base 1 is fixed on the ground or the wall surface through the positioning plate 14 and the positioning bolt 15, the switch is placed between the two fixing frames 2 in the base 1, and the circuit is inserted into the circuit groove 9 on the elastic plate 8, so that the switch is conveniently fixed and protected, and the circuit is conveniently combed;

when a switch is fixed, firstly, a knob is rotated clockwise, the knob drives a worm wheel 10 to rotate clockwise through a worm 11, the worm wheel 10 drives two cylinders 5 to rotate clockwise along a rectangular groove 3 through a guide rod 4, when inclined planes of the two cylinders 5 rotate from top to bottom to outside, the cylinders 5 drive two auxiliary plates 6 to slide relatively along a base 1 through a push rod 7, a tension spring 12 is stretched to enable the two auxiliary plates 6 to drive two fixing frames 2 to slide relatively along the base 1 to be in contact with the switch, the knob is not rotated at the moment, the worm wheel 10 and worm 11 structure has certain self-locking performance, the fixing frames 2 can be in a stable position to fix and protect the switch, and a rubber pad 16 and a ventilation groove 13 are arranged, so that the switch is protected conveniently and the switch can be better cooled;
