Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

As shown in fig. 1, this embodiment includes a fishing head assembly 7 and a plunging head assembly 6. The above is present in the conventional fishing device, and the structure thereof is well known to those skilled in the art, and therefore, the detailed description thereof is omitted.

As shown in fig. 1, the innovation of the present invention lies in: the device is characterized by also comprising a handle 1, a sliding rod 2, a power-assisted sliding sleeve 3 and a mounting seat 5, wherein the handle 1 and the mounting seat 5 are respectively fixedly arranged at two ends of the sliding rod 2, the power-assisted sliding sleeve 3 is slidably arranged on the sliding sleeve, and bosses 4 with limiting functions are correspondingly arranged on the upper side and the lower side of the sliding rod 2 corresponding to the upper side and the lower side of the power-assisted sliding sleeve 3; the fishing head assembly 7 and the throwing head assembly 6 are both arranged on the end surface of the mounting seat 5.

The working principle is as follows:

the utility model discloses a with tradition fishing head subassembly 7 on the ware of dragging for and drop into head subassembly 6 and install on a base structure who comprises slide bar 2, helping hand sliding sleeve 3 and mount pad 5, can realize the quick replacement of blanking plug on ground, improved work efficiency by a wide margin, reduced workman's intensity of labour. When the device works, the water distributor with the plug to be replaced is placed on the ground (clamping is not needed), and then one end of the mounting seat 5 is inserted into the water distributor. After confirming that the blanking plug in the water distributor is clamped by the fishing head assembly 7, the assisting sliding sleeve 3 is held by hand to continuously impact the boss 4 on one side of the handle 1, so that the blanking plug in the water distributor is gradually separated from the water distributor body, and then the blanking plug in the water distributor is taken out. Then, install the blanking plug of replacing usefulness on dropping into head subassembly 6, will again the utility model discloses whole rotatory 180 degrees, then will install the blanking plug that drops into on chuck 15 and send into the water injection mandrel, the blanking plug takes one's place and automatic card is after on the water injection mandrel, and 3 boss 4 on striking slide bar 2 of rethread slip helping hand sliding sleeve finally will the utility model discloses wholly take out, accomplish the change of blanking plug.

As shown in fig. 2, the fishing head assembly 7 further comprises a mounting joint 8, a collet 15 and a fixing sleeve 10, the mounting joint 8 is fixedly connected to the mounting base 5, the collet 15 is slidably inserted into the inner side of the mounting joint 8, a first spring 11 is arranged between the mounting joint 8 and the collet 15, and the collet 15 always keeps away from the mounting joint 8 under the elastic force of the first spring 11; the lower end of the clamping head 15 is provided with a first elastic claw 14 for grabbing the blanking plug, the fixing sleeve 10 is arranged on the outer side of the first elastic claw 14, the inner side of the lower end of the fixing sleeve 10 is attached to the outer side of the lower end of the first elastic claw 14, and the function of limiting the outward deviation of the first elastic claw 14 is achieved; the middle of the inner side of the fixing sleeve 10 is provided with a space for the outward deflection of the first elastic claw 14. When the blanking plug is used, the upper end of the blanking plug is inserted into the inner side of the fixing sleeve 10 and pushes the clamping head 15 upwards, when the outer side of the first elastic claw 14 is separated from the constraint of the fixing sleeve 10, the first elastic claw 14 expands outwards, the upper end of the blanking plug is further inserted into the inner side of the first elastic claw 14 and is clamped by the elastic claws, and after the clamping head 15 falls back again under the action of the first spring 11, the upper end of the blanking plug is completely locked by the first elastic claw 14 and cannot fall off, so that the clamping reliability is ensured.

As shown in fig. 2, a bolt 16 is disposed on a side surface of an upper end of the chuck 15, both ends of the bolt 16 extend out from a side surface of the upper end of the chuck 15, a slide way is disposed inside the mounting connector 8 corresponding to the bolt 16, both ends of the bolt 16 are inserted into the slide way, the chuck 15 is pressed from a lower end of the chuck 15, and the chuck 15 can alternatively stay at two stable positions with different axial positions under cooperation of the slide way and the bolt 16.

Fig. 3 is a plane development view of the slide in the present application, in which the latch 16 always keeps a movement trend toward the right-hand limit position in the figure under the elastic force of the first spring 11, and after the collet 15 is pushed upward by the obturator each time, the collet 15 can be switched between two different axial positions, and when the collet 15 is at the upper limit position, the outer side of the first elastic claw 14 is separated from the constraint of the fixing sleeve 10, so that the obturator can be pulled out from the inner side of the first elastic claw 14, and when the collet 15 is at the lower limit position, the outer side of the first elastic claw 14 is constrained by the fixing sleeve 10, so that the obturator cannot be pulled out from the inner side of the first elastic claw 14. It should be noted that the purpose of the slide in this solution is to provide two different axial positions for the collet 15 in order to achieve both the gripping and releasing actions of the obturator by means of a push. The mechanism is applied to a push pen and hardware for opening and closing a cabinet door of furniture, so that the slideway structure does not belong to the protection range of the application.

As shown in fig. 2, a second elastic claw 13 is processed at the lower end of the fixed sleeve 10, a lock sleeve 12 for limiting the second elastic claw 13 is arranged on the outer side of the second elastic claw 13, the lock sleeve 12 is slidably mounted on the outer side of the fixed sleeve 10, a second spring 9 is arranged on the outer side of the fixed sleeve 10, and the lock sleeve 12 always keeps away from the movement tendency of the mounting joint 8 under the elastic force of the second spring 9. The second elastic claw 13 and the lock sleeve 12 are arranged to ensure that the blanking plug can be smoothly taken down when the chuck 15 is locked.

In specific implementation, the material of the fixing sleeve 10 and the chuck 15 is preferably 65Mn, which is beneficial to ensure the toughness and elasticity of the first elastic claw 14 and the second elastic claw 13.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
