The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, upside down fastened safe fishing spear of the present invention, comprise the fixed support 2 being fixed on ground 1, the middle part of fixed support 2 is provided with linear bearing 3, above described fixed support 2, be provided with cylinder 4, cylinder 4 is fixed on fixed support 2 by air cylinder support 5, expansion link 6 in described cylinder 4 runs through linear bearing 3, be used in the interior slip of linear bearing 3, the lower end of described expansion link 6 is provided with fixed cover 7, the bottom surface of fixed cover 7 is provided with a plurality of arc spring laminations 8, the lower end of each arc spring lamination 8 is provided with one for holding up the oil pipe base 10 of oil pipe 9, oil pipe base 10 is provided with for the roller 11 in oil pipe 9 interior slips, can reduce like this frictional force between oil pipe base 10 and oil pipe 9.
By a preferred embodiment of the present invention, described oil pipe base 10 and arc spring lamination 8 integrated setting.
By a preferred embodiment of the present invention, the described expansion link 6 being placed in fixed cover 7 is provided with the first through hole 12, on the sidewall of fixed cover 7, the position of corresponding the first through hole 12 is provided with the second through hole 13, and described fixed cover 7 runs through the first through hole 12 by pin 14 and the second through hole 13 is fixed on expansion link 6.
