The implementation manner of the embodiment is as follows: firstly, the fixing unit 100 is required to be installed at the bottleneck of a needle-type electric porcelain bottle, the poking rod 104b is poked to enable the locking piece 104 to be separated from the ratchet wheel 103a, one end of the second clamping ring 103 is separated from the fixed seat 102, then the first clamping ring 101 is sleeved at the bottleneck of the porcelain bottle, the ratchet wheel 103a is inserted into the fixed seat 102 and matched with the inner ratchet wheel 104a according to the diameter of the bottleneck of the porcelain bottle, and at the moment, the diameter of a ring formed by combining the first clamping ring 101 and the second clamping ring 103 is smaller and smaller until the ring is tightly embraced at the bottleneck of the porcelain bottle; next, the wire to be fixed is placed in the groove of the needle-type electric porcelain bottle, and the wire is located between two mating wire holder seats 301, two plugs 302b of the fixing clip 302 are aligned with the insertion holes 301a of the wire holder seats 301, at this time, the wire is located in the bent piece 302a of the fixing clip 302, then, the fixing clip 302 is pressed to insert the plug 302b into the insertion hole 301a, the stopper 303 contacts the stopper rod 304 and presses the stopper rod 304 to retract the stopper rod 304 into the stopper groove 301b, when the stopper 303 passes over the stopper rod 304, the stopper rod 304 is no longer restrained, under the elastic force of the first spring 305, the first spring extends into the insertion hole 301a and abuts against the circular truncated cone 302a-1 and the groove of the bending piece 302a and the limiting piece 303, at this time, the horizontal surface 304b contacts with the end surface of the stopper 303 to restrict the bent piece 302a from being separated, and the fixing clip 302 is mounted.

When the lead needs to be removed, firstly, the fixing clip 302 needs to be continuously pressed to enable the round table 302a-1 to further extend into the insertion hole 301a, at this time, the second cone 306 is in contact with the inclined plane 304a, in the process that the round table 302a-1 is continuously pressed, the limiting rod 304 is extruded into the limiting groove 301b, when the large-diameter end face of the second cone 306 passes over the limiting rod 304, the limiting rod 304 is not restrained any more, extends into the insertion hole 301a under the action of the elastic force of the first spring 305 and abuts against the conical surface of the second cone 306, and then, the fixing clip 302 can be pulled out outwards, and the specific process is as follows: the horizontal surface 304b of the limiting rod 304 prevents the second cone 306 from moving, so when the circular truncated cone 302a-1 moves, the limiting rod 304 pushes the second cone 306 to move toward the limiting member 303 until the large diameter end of the second cone 306 contacts with the limiting member 303, and at this time, the limiting rod 304 separates from the limiting member 303 along the surface of the second cone 306, i.e. the whole fixing clip 302 is not constrained, and can be pulled out, and in another case, when the elastic force of the second spring 307 loses effect, other operations are needed to complete the separation, mainly, the rotating member 308 rotates to make the connecting rod 304c move from the first end 308a-1 to the second end 308a-2 in the adjusting groove 301c, because when the rotating member 308 rotates, the coinciding position of the adjusting groove 301c and the long groove 308a gradually moves away from the center of the rotating member 308, i.e. the connecting rod 304c and the limiting rod 304 move away from the center of the rotating, the round bench 302a-1 is separated, so that the whole fixing clamp 302 can be pulled out; the fixing unit 100 needs to be disassembled, and the first snap ring 101 can be separated from the fixing seat 102 and then the needle-type electric power porcelain bottle only by rotating the adjusting ring 202 to make the boss 203 move from the first side 202a-1 to the second side 202a-2 at the inclined groove 202a to make the locking piece 104 separate from the ratchet gear 103a, at this time, the first snap ring 101 is not limited by the position any more.

According to the invention, the handcuff type fixing unit 100 is tightly clasped at the bottleneck of the needle type electric power porcelain insulator, then the wire is easily fixed through the wire clamp unit 300, the installation and the disassembly are convenient, manpower and material resources are saved, and the operation efficiency of workers is improved.
