Preferably, described connecting rod is J type structure; Connecting rod is arranged to the structure with arc, is utilizing lever principle to carry outWhen write off, what the first cylinder place was provided is just in time the power of outwards pulling out R pin, can provide larger for the first cylinder place simultaneouslyPower R pin is pulled out.
Rectilinear end and the Handheld Division of described J type structure are affixed, and camber line end and the operating portion of J type structure are affixed.
The diameter dimension of described the first cylinder is less than the diameter dimension of R pin round mouth; Conveniently the first cylinder is inserted in R pin round mouth.
The diameter dimension of described the second cylinder is greater than the diameter dimension of the first cylinder; Make the second cylinder provide enough as fulcrumSupport force.
Preferably, the diameter dimension of described the second cylinder is 1.5 times of diameter dimension of the first cylinder; The diameter of the second cylinderThe too small support force that provides required of being not enough to, the excessive waste that easily causes resource of diameter.
Preferably, described Handheld Division is slab construction, and slab construction is provided with circular hole; Slab construction can be used for beaing object,Circular hole is set can be hung on this pin removal on the hook of staff's safety belt, is convenient for carrying.
Described slab construction is mutually vertical with the plane at J type structure place; Facilitate staff in use Handheld Division to be carried outThe application of force.
Preferably, the axis direction of described the first cylinder and the second cylinder is all mutually vertical with the rectilinear end of J type structure; Like thisSetting coordinates whole pin pulling device structure becomes best lever form, makes the process of pulling pin the most laborsaving smooth and easy.
Operation principle of the present invention is:
When use, the first cylinder is placed in to R pin round mouth, the second cylinder is pressed on insulator bowl head outside, with the second postBody is fulcrum, and Handheld Division is force position, and the first cylinder is stress point, utilizes lever principle that R pin is taken out. By connecting rodBe arranged to the structure with arc, make the application of force of pin removal more meet ergonomics, more easily R pin is taken out.
Beneficial effect of the present invention is:
Pin removal of the present invention, by the setting of the first cylinder and the second cylinder and connecting rod and Handheld Division, forms lever construction,Utilize lever principle to carry out write off, solved and when original pin pulling clamp is pulled pin, be difficult to the difficult problem of clamping and wasting time and energy.
The connecting rod of pin removal of the present invention is arranged to the J type structure with arc, and what the first cylinder place was provided is just in time outsidePull out the power of R pin, can pull out R pin for the first cylinder place provides larger power simultaneously.
The Handheld Division of pin removal of the present invention is set to slab construction, and circular hole is set thereon, and slab construction can be used for beaingObject, circular hole is set can be hung on this pin removal on the hook of staff's safety belt, is convenient for carrying.
