Fig. 2 is a kind of use state diagram of anchor pole catching device described in the utility model embodiment.

Specific embodiment

For convenient for those skilled in the art understand that technical solutions of the utility model, practical new to this now in conjunction with Figure of description Type technical solution is described further.

Fig. 1 show the schematic diagram of anchor pole catching device in the original state described in the present embodiment, including loop bar 1, motion bar 2, return unit 3.

The loop bar 1 is hollow rod body, and one end of loop bar 1 is equipped with fixed grapple 4；The motion bar 2 is set to loop bar 1 It is interior, and can be slided along 1 axis of loop bar, the both ends of motion bar 2 are stretched out respectively outside loop bar 1, and it sets close to one end of fixed grapple 4 There is movable grapple 5.The activity grapple 5 constitutes anchor pole clamping part with fixed grapple 4.

The return unit 3 includes spring 31, first baffle 32 and second baffle 33, and the spring 31 is located in loop bar 1, and It being sheathed on motion bar 2, the first baffle 32 is connected with motion bar 2, and is located at one end of the close fixed grapple 4 of spring 31, The outer diameter of first baffle 32 is greater than the outer diameter of spring 31；The second baffle 33 is connected with 1 inner wall of loop bar, is offered thereon for work The perforative through-hole of lever 2 (being mark in figure), second baffle 33 is located at one end that spring 31 deviates from fixed grapple 4.The reset Part 3 is at least one, is preferably two in the present embodiment, and in two equal loop bars 1 of return unit 3, and be located at 1 liang of loop bar End.

Further, the motion bar 2 is equipped with flexible handle 6 far from the end of movable grapple 5.The flexible handle 6 Including the first hand-held part 61 perpendicular to 3 axis of motion bar, first hand-held part 61 passes through first connecting portion 62 and motion bar 3 Connection.One end that the loop bar 1 deviates from fixed grapple 4 is equipped with fixed handle 7, and the fixed handle 7 includes the second hand-held part 71, Second hand-held part 71 is parallel to the first hand-held part 61, and the second hand-held part 71 is connect by second connecting portion 72 with loop bar 1.No When grabbing anchor pole, there are a spacing between the first hand-held part 61 and the second hand-held part 71.

It is the use state diagram of anchor pole catching device described in the present embodiment refering to Fig. 2.When needing to grab anchor pole, on the other hand Hold loop bar 1, it is another be manually placed at it is first-hand hold at portion 61 and the second hand-held part 71, first move catching device, enter anchor pole Gap between fixed grapple 4 and movable grapple 5, the first hand-held part 61 of then holding with a firm grip make it think that 71 direction of the second hand-held part is moved It is dynamic, the gap shrinks between grapple 4 and movable grapple 5 are fixed at this time, and step up anchor pole, while spring 31 is compressed.Anchor pole is taken After out, the first hand-held part 61 is unclamped, under the action of recoil of spring power, the first hand-held part 61, movable grapple 5 return to initial bit It sets, completes to reset.

In use, it to avoid motion bar 2 from rotating, is equipped in the loop bar 1 axially extending along loop bar 1 Limiting slot 8, the motion bar 2 are equipped with position limiting slide block 9 corresponding with limiting slot 8.Pass through matching for position limiting slide block 9 and limiting slot 8 It closes, so that motion bar 2 can only be axially moveable.
