In figure: 1. counter weight, 2. guide thimble, 3. guide post, 4. limit connector, 5. stop pin, 6. stud, 31. blocks, 311.U type groove, 61. first spiral shell heads, 62. second spiral shell heads.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are further described.
As Figure 1-3, a kind of pin extractor improving operator's security, comprise counter weight 1, guide post 3, stud 6, also comprise guide thimble 2 and limit connector 4, described guide thimble 2 is one end open, the hollow circular cylinder that the other end is closed, one end of described guide post 3 pass described guide thimble 2 blind end and can along the axially reciprocating of described guide thimble 2, the other end of described guide post 3 is provided with block 31, described guide post 3 passes one end of described guide thimble 2 and described limit connector 4 one end removably connects, the other end of described limit connector 4 and one (the first spiral shell head 61) of described stud 6 removably connect, the other end (the second spiral shell head 62) of described stud 6 is connected with the internal thread having treated directly to pull pin, openend and the described counter weight 1 of described guide thimble 2 removably connect, and described counter weight 1 is located at the openend of described guide thimble 2.
The mode of removably connecting of described counter weight 1 and described guide thimble 2 can for being threaded, pin joint, the various mode such as clamping, pin joint can be a pin diameter to running through counter weight 1 and guide thimble 2, also can be the wall that two or many pins run through counter weight 1 and guide thimble 2.
In the present embodiment, counter weight 1 and described guide thimble 2 run through counter weight 1 and guide thimble 2 by stop pin 5 radial direction, simultaneously, conveniently operate, when avoiding the second spiral shell head 62 to be connected with the internal thread of directly pulling pin, guide post 3 rotates, and described block 31 top is provided with the U-type groove 311 coordinating with stop pin 5 and prevent guide post 3 from rotating.
