Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further details:
As it is shown in figure 1, the utility model discloses a kind of instrument extracing bird's nest, including head 1 and shaft 2, head 1 is fixed on shaft 2 one end；Head 1 includes back taper cap 1-1 and barb 1-2, back taper cap 1-1 is uniformly arranged on back taper cap 1-1 inside circumference face can reduce the head 1 resistance when penetrating bird's nest, the back taper cap 1-1 of head 1 is that bird's nest can be penetrated down over by cone-shaped structure from bird's nest, and the barb 1-2 of head 1 can hold whole bird's nest below bird's nest；Shaft 2 includes straight bar section 2-1 and knee section 2-2, and knee section 2-2 is connected to the upper end of straight bar section 2-1, and knee section 2-2 is it can be avoided that operator need to stand in the underface of bird's nest at work.
As in figure 2 it is shown, the barb 1-2 in head 1 is arranged on back taper cap 1-1 inside circumference face by spring pressuring plate 1-3, the lower end of spring pressuring plate 1-3 is fixedly connected on back taper cap 1-1 inside circumference face, and the upper end of spring pressuring plate 1-3 is connected with the lower end of barb 1-2；Barb 1-2 can be by completing action of shrinking and scatter under the effect of spring pressuring plate 1-3, spring pressuring plate 1-3 can keep barb 1-2 and head 1 centrage to be the angle of 15～30 ° under barb 1-2 is without stress, and to keep barb 1-2 and head 1 centrage under barb 1-2 stress be the angle of 0～60 °；According to practical experience, barb 1-2 freely uses in the confined space for convenience, preferably with head 1 centrage, barb 1-2 is set to 25 degree, and the length of barb 1-2 is set to 7cm, and the bending radius of knee section 2-2 is set to 15cm.Barb 1-2 includes that appearance is wound around the spring steel plate of empire cloth, spring steel plate self-strength is big, durable, deform strong with recoverable force ability, even if not having spring pressuring plate 1-3 can complete the Flexible change of self yet, meet requirement, add that appearance is wound around empire cloth and also can keep self insulating, meet safety when electric power tool needs ensure operation on line.
As in figure 2 it is shown, arrange at least three barb 1-2 in head 1, the angle between centrage and the centrage of head 1 of barb 1-2 is 0 °～60 °；Barb 1-2 keeps the angle of 15～30 ° with the centrage of head 1 under without force-bearing situation, barb 1-2 is being reduced to the centrage of head 1 be the angle of 0 ° to recovery through while bird's nest with back taper cap 1-1, barb 1-2 with back taper cap 1-1 through after bird's nest in the angle without stress recovery 15～30 °, at least head 1 barb 1-2 when upwards removing bird's nest can be made to scatter and whole can hold bird's nest with three barb 1-2, barb 1-2 inserts in bird's nest during holding bird's nest, and allows barb 1-2 stress and head 1 centrage to have the angle change of maximum 60 °.
As shown in Figure 3, barb 1-2 draws rope group 3 in barb and is connected, barb draws rope group 3 in and includes the lower end being connected to barb 1-2 and stretch into the end pulling rope 3-1 of head 1 inner chamber, main stay cord I 3-2 being arranged in knee section 2-2 and main stay cord II 3-3 being arranged in straight bar section 2-1, and one end of main stay cord I 3-2 is connected with end pulling rope 3-1, the other end stretches out knee section 2-2 and is connected with main stay cord II 3-3；Barb draws rope group 3 in and barb 1-2 can be pulled to shrink, and reduces the head 1 resistance when penetrating bird's nest.
As it is shown in figure 1, knee section 2-2 arranges four between angle of bend 90～180 ° connects end bar 2-2-1, arranging main stay cord I 3-2 in the inside of each connection end bar 2-2-1, four connect end bar 2-2-1 and all can be threaded connection with straight bar section 2-1；Connect the shaft 2 after end bar 2-2-1 can make assembling and adapt to meet the operation of different angles under various operating environments, avoid bird's nest in operation directly to drop on the operating personnel crown simultaneously.
Straight bar section 2-1 is threaded connection mode by more piece hollow pipe and is connected with each other and forms；Hollow pipe can reduce deadweight, and the mode of being threaded connection is connected with each other, and can arrange the length of straight bar section 2-1, the convenient bird's nest being suitable for various height flexibly.
Operation principle and using method:
As shown in Figure 1, Figure 3, according to the needs of actual bird's nest height Yu position, being assembled by shaft 2, and barb draws in rope group 3, and to penetrate shaft 2 internal, end pulling rope 3-1 becomes three stocks not connect three barb 1-2, main stay cord II 3-3 to pass shaft 2 end.
As in figure 2 it is shown, barb 1-2 is the angle of 15～30 ° with head 1 centrage under the effect of spring pressuring plate 1-3, during head 1 penetrates bird's nest above bird's nest, it is 0 ° that barb 1-2 shrinks with head 1 centrage；After head 1 penetrates bird's nest above bird's nest, barb 1-2 opens and holds whole bird's nest, and during firmly being held up by whole bird's nest then up, it is 60 ° that barb 1-2 opens with head 1 centrage, and then is disposably removed by bird's nest.
This utility model all uses insulation to arrange in addition to spring pressuring plate 1-3, it is ensured that can livewire work.
Application this utility model disposably can fall bird's nest overall pulling down, it is to avoid bird's nest is scattered, and the phenomenon affecting sight line occurs, and operating personnel, without junk of dodging, improves the safety guarantee of operating personnel；And easy to use, the excision bird's nest operating time is short, substantially increases the work efficiency removing bird's nest, improves the reliability of line security stable operation；Simultaneously can uninterrupted operation, it is not necessary to could remove bird's nest until line outage overhaul, reduction circuit is because of bird's nest trip-out rate, it is ensured that circuit continued power, and increase electricity sales amount is increased economic efficiency, and low cost, be prone to produce in batches.
