With the hinged U-shaped union joint of grafting pin, there is hanging screw in the middle setting of U-shaped union joint.This device passes through handle and company
Bar forms the elbow-bar mechanism of reinforcement, pulls pull bar to reach the purpose pulling out pin by elbow-bar mechanism, structure is simple, user
Just, but both sides launch handle take up room excessive, not portable；China Patent No.：201520237520.4 disclosing one
Plant hydraulic pressure pin inserting-drawing mechanism, including base, hydraulic jack, stator, connecting rod, three contiguous blocks and adapter sleeve, base passes through
Bolt of lower base is fixedly connected the bearing pin support of big part bearing pin, and hydraulic jack is fixed on base for fitted bolt by stator,
Connecting rod includes long whorl brace rod and short thread connecting rod, passes through contiguous block and adapter sleeve connects between length whorl brace rod,
Connecting rod two ends connect the grooved piston bar of big part bearing pin and hydraulic jack respectively, make big part bearing pin, long whorl brace rod, short spiral shell
On the same axis, this device provides power to realize pin is plugged and unplugged by hydraulic cylinder, saves for stricture of vagina connecting rod, grooved piston bar
Manually carry out plug operation, but hydraulic pressure pulling-out mechanism build is heavy, not portable, and production cost is high.
Utility model content
Therefore, for above-mentioned problem, this utility model provides a kind of new pulling-out mechanism, and it mainly solves existing
The problem that in technology, pulling-out mechanism build is heavy, not portable, production cost is high.
For achieving the above object, this utility model employs technical scheme below：A kind of new pulling-out mechanism, including drawing
Dead man, lever, impact block, connector, protective case, the middle part of described lever is laterally positioned in the upper end of drawing bar, described punching
Hit block to be set in the week side of boss of drawing bar and can slide up and down along drawing bar, left and right two sides of described impact block are all inside
Depression is provided with arcwall face for the hand placement of convenient use person, and described connector is dismountable to be arranged under drawing bar
End, described connector lower end is provided with the threaded rod being coaxially disposed with drawing bar, and described protective case is removably set in connector
Above it is used for cover lid threaded rod.
Further, the outer surface of described drawing bar is located at and is arranged with retainer ring between impact block and connector, described solid
The outer surface determining ring is provided with mounting blocks, and described mounting blocks are provided with screwed hole, and described mounting blocks are provided with expansion link, institute
State expansion link to be connected with mounting blocks by bolt.
Further, the bottom of described drawing bar is arranged to the T-shaped of handstand, and the side of described connector is concaved with
Matched the T-shaped groove of clamping with described T font.
Further, threadeded with connector in the lower end of described drawing bar.
By adopting preceding solution, the beneficial effects of the utility model are：This new pulling-out mechanism passes through drawing
Impact block is designed on bar, user lifts impact block manually and clashes into lever so that the round pin of connector connection is in impact upwards
Under extract, realize the drawing of round pin, connector is detachably connected with drawing bar, thus the connector of more preferable different model, convenient
Connector is connected with the round pin of different model, and protective case can protect the outer spiral shell threadeded on connector with round pin
Stricture of vagina, prevents external screw thread to be destroyed, this mechanism is easy to use, and compact structure is easy to carry；Further, by retainer ring with stretch
Contracting bar connects so that expansion link supports drawing bar, and in use, drawing bar can be by vertically solid under expansion link effect
Determine to live, convenient use person is clashed into impact block force；Further, by T-shaped fixture block with snap connection, conveniently connect
The quick-replaceable of fitting.
Brief description
Fig. 1 is the structural representation of this utility model embodiment.
Specific embodiment
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
This utility model embodiment is：
Reference Fig. 1, a kind of new pulling-out mechanism, including drawing bar 1, lever 2, impact block 3, connector 4, protective case 5,
