Abstract
The utility model discloses a kind of change rails to be detached from fishing socket, including cylinder, slips, the body of rod, become rail set and becomes rail pin, the inside of the cylinder has cavity and cavity is truncated cone-shaped, the slips is arranged in the cavity of the inner barrel, the junction of the cylinder inboard wall and the slips is provided with inclined-plane, the body of rod is connect with one end of the slips, the change rail set is sleeved on the body of rod, the cylinder is by the slips and becomes rail set suit, the change rail pin is inserted radially into from the drum surface and extends in the change rail set, change rail set surface, which is provided with, becomes rail track.The utility model, which generates to be displaced and slips is further enable to generate inward radial force by the inclined-plane of slips and cylinder inboard wall, is firmly secured to slips in slips fish；Entering the release track become in rail track by pin can be such that slips separates with the inclined-plane of cylinder, so that fish be made to fall off.
Description
Technical field
The utility model belongs to mechanical equipment technical field, specifically, being related to a kind of change rail disengaging fishing socket.
Background technique
In previous fishing tool, fishing tool is not easy to fall off fish from slips after holding fish.
Utility model content
For deficiency above-mentioned in the prior art, the utility model provides a kind of change rail disengaging fishing socket.
In order to achieve the above object, the solution that the utility model uses is: providing a kind of change rail disengaging fishing socket, packet
Cylinder is included, slips, the body of rod, becomes rail set and becomes rail pin, the inside of the cylinder has cavity, and the slips is arranged in the cylinder
In the cavity in internal portion, the junction of the cylinder inboard wall and the slips is provided with inclined-plane, the body of rod and the slips
One end connection, the change rail set are sleeved on the body of rod, and the cylinder is by the slips and becomes rail set suit, the change rail pin
Nail is inserted radially into from the drum surface and extends in the change rail set, and change rail set surface, which is provided with, becomes rail track.
Further, one end on the cylinder far from the slips is provided with top connection, and the other end of the cylinder is set
It is equipped with guide shoe.
Further, the guide shoe uses 45 degree of tooth mouth guide shoes.
Further, it is connected between the slips and the top connection by spring.
Further, the slips is provided with suspension stud close to one end of the change rail set.
It goes forward side by side the beneficial effects of the utility model are: the utility model generates displacement by the inclined-plane of slips and cylinder inboard wall
One step enables slips generation inward radial force that fish is firmly secured in slips by slips；Enter change by pin
Release track in rail track can be such that slips separates with the inclined-plane of cylinder, so that fish be made to fall off.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
In attached drawing: 1, cylinder；101, inclined-plane；2, slips；3, the body of rod；4, become rail set；401, become rail track；5, become rail pin
Nail；6, top connection；7, guide shoe；8, stud is hung；9, spring.
Specific embodiment
The utility model is further described below in conjunction with attached drawing:
The utility model provides a kind of change rail disengaging fishing socket, as shown in Figure 1, including cylinder 1, slips 2, the body of rod 3, becoming rail
Set 4 and change rail pin 5, the inside of cylinder 1 have cavity, and slips 2 is arranged in the cavity inside cylinder 1,1 inner wall of cylinder and card
Watts 2 junction is inclined-plane 101, and slips 2 can move in cylinder 1, and the body of rod 3 connect with one end of slips 2,4 sets of set of change rail
On the body of rod 3, cylinder 1 is by slips 2 and becomes 4 suit of rail set, becomes rail pin 5 and is inserted radially into from 1 surface of cylinder and extends to change
In rail set 4, pin 5 becomes 4 surfaces of rail set and is provided with change rail track 401 cylinder 1 and slips 2 to be fixed together.
In the present embodiment, one end on cylinder 1 far from slips 2 is provided with top connection 6, and the other end of cylinder 1, which is provided with, to be drawn
Fish can more easily be introduced into slips 2 by shoes 7, guide shoe 7, at the same time the one end of cavity far from guide shoe 7 in cylinder 1
End area be greater than close to 7 one end of guide shoe end area.
In the present embodiment, pass through spring connection 9 between slips 2 and top connection 6.
In the present embodiment, guide shoe 7 uses 45 degree of tooth mouth guide shoes.
In the present embodiment, slips 2 is provided with suspension stud 8 close to the one end for becoming rail set 4, and suspension stud 8 can make slips 2
It links together with the body of rod 3.
When the working principle of the utility model is such that fish need to be salvaged, by the utility model lower going-into-well, work as downlink
After slips 2 is contacted with fish when to fish position, spring 9 is compressed after slips 2 receives the top power of fish, and slips 2 is also in cylinder 1
Interior movement, since slips 2 is kept in mind, the increasing direction of 1 internal cavity cross-sectional area of cylinder is mobile, and the interior of slips 2 is also increased
Add, fish can smoothly enter in slips 2, then above mention the utility model, and slips 2 is influenced by the gravity of itself and fish
And can be mobile towards the smaller and smaller direction of 1 internal cavity cross-sectional area of cylinder, therefore the radial pressure that slips 2 receives increases, card
Watts 2 internal diameter becomes smaller, therefore can sting fish tightly, continues thereafter with and mentions the utility model and can salvage fish.Then,
Can not move during slips 2 above mentions indicates that fish is stuck in well, continues traveling downwardly the utility model pin 5 at this time
It will enter and become in the change rail track 401 on rail set 4, such pin 5 cannot be fixed by slips 2 and cylinder 1 again, therefore
Slips 2 also would not again by the pressure of 1 inner wall of cylinder, slips 2 it is interior increased, fish in slips 2 also just with slips 2
It is whole stuck in well by fish to can be avoided the utility model in this way for natural separation.
Specific embodiment of the present utility model above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.
