A quick-release includes axle having a head and an outer threaded end formed to two ends thereof. The axle is threadedly connected to the chain stay of a bicycle. The axle includes a passage defined axially therethrough. A groove is formed radially through the head, and two recesses are respectively formed in two insides of the groove. A knob is fitted in the groove of the head. A rod is movably located in the passage and has an engaging end which is connected to the knob. A ball is formed to the rod. A non-circular hole is formed in the ball. When the rod is pulled and the ball is rotatably engaged with the two recesses, the rod is pivoted and partially engaged with the groove so as to rotate the axle to esparto the wheels from the chain stay.

A light source assembly includes a light source unit, a light collecting unit, a light separating unit and a light converting unit. The light source unit generates a first light beam having a first color and a first optical path. The light collecting unit has a light entering side and a light exiting side and is configured to collimate and condense the light beam incident on the light entering side. The light separating unit is disposed on an area between the light entering side and the light exiting side of the light collecting unit for reflecting the first light beam entering from the light entering side of the light collecting unit. The light converting unit absorbs the first light beam reflected from a light separating unit and generates a converted light beam having a second color.

A method for vertically grounding and leading down form a center of a composite pole tower includes the following steps: extending a ground down-leading wire from a center of a ground wire cross arm which is made of metal and is positioned on top of the pole tower, wherein the ground down-leading wire is vertically leaded down to the earth form the center of the composite pole tower, wherein when an lower portion of the tower body is a metal pipe, the ground down-leading wire is extended from the center of the composite material and is directly connected to the metal pipe. The method utilizes the advantage of the insulating intensity of the wall of the composite pole tower and enhances the insulating intensity of the transmission line on impact of lightning. The ground down-leading wires are prevented from short-circuiting with the tower body of the composite pole tower, so that advantage of the insulating property of the composite material of the pole towers is realized. Since the ground down-leading wire is penetrated through center of the pole tower, so that the ground down-leading wires are not exposed and are prevented from destroying by external force. And also the method is easy and simple for application.

A method for vertically grounding and leading down form an inner side of a composite pole tower and pole tower thereof, wherein the method includes the following steps: extending an upper metal cross arm from an extended line of at least one side of a ground wire cross arm which is made of metal, vertically leading down a ground down-leading wire from a distal end of the upper metal cross arm, connecting the ground down-leading wire to the pole tower via a lower metal cross arm at a distance under a lower lead, and grounding the ground down-leading wire along a tower body of the pole tower, wherein when an lower portion of the tower body is a metal pipe, the ground down-leading wire is selectively directly connected to the metal pipe via the lower metal cross arm. The upper metal cross arm and the lower cross arm are able to provide a distance between the ground down-leading wire and the pole tower. The method enhances the ability of bearing lightning flashover, increases the insulating intensity to lightning impact, and prevents burning to composite insulator by power-flow current after lightning flash over. And also the method is easy and simple for application.

A method for vertically grounding and leading down form an outer side of a composite pole tower and pole tower thereof, wherein the method includes the following steps: extending an upper metal cross arm from an extended line of at least one side of a ground wire cross arm, vertically leading down a ground down-leading wire from a distal end of the upper metal cross arm, connecting the ground down-leading wire to the pole tower via a lower metal cross arm at a distance under a lower lead, and grounding the ground down-leading wire along a tower body of the pole tower, wherein when an lower portion of the tower body is a metal pipe, the ground down-leading wire is selectively directly connected to the metal pipe via the lower metal cross arm. The method facilitates in compressing the width of the transmission corridor to a maximum extent as well as designing a lightning protection, preventing the ground down-leading wire from short-circuiting with the tower body, and realizing the insulation function of the composite material tower body. The manner of using unilateral ground down-leading wire saves material, and is economical and simple in structure.
