As a further preferred aspect of the present invention, the thread of one end of the jaw rod and the lock nut screw-connected is longer than the thread of one end of the arrow screw-connected.
As a further preferred scheme of the utility model, lock nut is butterfly nut.
As a further preferred scheme of the utility model, arrow point, jaw pole, lock nut, coupling nut, activity dartlike weapon leaf, bolt all make with solid stainless steel.
As a further preferable aspect of the present invention, the movable dart blade is longer than the rectangular through hole provided by the arrow.
As a further preferred scheme of the utility model, the activity darts the leaf and is equipped with three sawtooth for two unanimous and outsides of shape.
As a further preferred aspect of the present invention, the movable dart blade is provided with a direction at the end of the movable dart blade with a certain inclination angle and a pointed end of the saw tooth.
Compared with the prior art, the utility model provides a safe efficient fish spear head possesses following beneficial effect:
the device can effectively solve the problem that fish in the arrowhead can slip off after stabbing, and the fish in the stabs can be clamped by the saw teeth of the movable dart blades or the whole dart blades no matter the stabbing is not performed, so that the catching efficiency is greatly increased; the increased movable dart blade can be used as a force application point to enable the arrow to be screwed down more easily and not to loosen easily, so that the whole device is safer.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, the utility model provides a safe and efficient fish spear head, which comprises an arrow head 1 and a movable dart blade 5, and is characterized in that the head of the arrow head 1 is provided with a conical head and the tail end is provided with an inner thread which is fixedly sleeved with a fork rod 2 in a spiral way; the fork head rod 2 is a cylinder, and the outer sides of two ends of the fork head rod are provided with screw threads; the other end of the fork rod 2 is spirally sleeved with the locking nut 3 in a penetrating manner through the thread and is fixedly connected with the connecting nut 4 in a spiral manner; a rectangular through hole is formed below the conical head of the arrow 1, and a movable dart blade 5 is arranged in the through hole; the movable dart blade 5 is provided with a through hole; arrow 1 is equipped with bolt 6 fixed connection, and bolt 6 runs through the through-hole of activity dartlike weapon leaf 5.
As a further preferred aspect of the present invention, the thread of one end of the screw connection of the fork rod 2 and the lock nut 3 is longer than the thread of one end of the screw connection with the arrow, so that the lock nut 3 can move in more places.
As a further preferred scheme of the utility model, lock nut 3 is butterfly nut, must better twist the nut, need not be with the help of the instrument, and is manual just can operate.
As the utility model discloses a further preferred scheme, arrow point 1, jaw pole 2, lock nut 3, coupling nut 4, activity dartlike weapon leaf 5, bolt 6 all make with solid stainless steel, and the stainless steel has corrosion resistance, and is difficult for rustting, and hardness ratio is bigger moreover, makes solid letting the harpoon have more power.
As a further preferred aspect of the present invention, the length of the movable dart blade 5 is longer than the rectangular through hole of the arrow 1, so that the movable dart blade 5 can be conveniently locked by the length advantage without completely entering the through hole.
As a further preferred scheme of the utility model, the activity darts leaf 5 for two unanimous and the outside of shape is equipped with three sawtooth.
As a further preferred scheme of the utility model, activity darts the 5 terminal directions that have certain inclination and the directional activity of sawtooth pointed end darts the leaf with sawtooth one side, and the sawtooth forms contrary tooth, when forking the fish, is difficult to let the fish escape.
As a specific embodiment of the present invention:
the arrow 1 is spirally and fixedly connected to the fork head rod 2, and the arrow can be screwed more tightly by taking the movable dart blade 5 as a power arm, so that the arrow is not easy to loosen, and is convenient to aim and safer; screwing the locking nut 3 into the thread at the other end, screwing the connecting nut 4, and screwing the locking nut 3 out to touch the connecting nut 4, so as to fix the jaw rod 2 and the connecting nut 4, and screwing the locking nut 3 in the direction of the connecting nut 4, so that the connecting nut 4 is not easy to loosen from the jaw rod; the movable dart piece 5 is in free shaft rotating connection through the bolt 6, when a fish is forked, the movable dart piece 5 can be retracted, but the reverse tooth on one side can well prevent the fish from falling off from the fish fork; once the fish is pierced, the two movable dart sheets 5 are pushed against the body of the fish to be unfolded and clamp the fish under the action of gravity or during recovery, so that the fish cannot fall off, after the harpoon is recovered, if the fish which is not pierced can only be pulled out with brute force, the pierced fish can be pulled out with little effort by using the movable dart sheets 5 as power arms to loosen the arrows, and the arrow 1 is separated from the fork rod 2 and then the fork rod 2 is pulled out.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
