Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Referring to fig. 1-4, the detection tool pull rod limit pin mechanism comprises:

a base 1, a pin cylinder 2 is arranged on the top of the base 1, a limit pin 3 is inserted in the center of the pin cylinder 2, and

the locating pin 5 of establishing in 3 outside both sides of spacer pin, long recess 4 has all been seted up to both sides around the round pin section of thick bamboo 2, and the left and right sides of round pin section of thick bamboo 2 has all seted up short recess 7.

Referring to fig. 1, the top of the stopper pin 3 is connected with a handle 6 through a nut.

Referring to fig. 1, via holes are formed on both sides of the top of the base 1.

Referring to fig. 3, the cross-section of the stopper pin 3 is stepped.

Referring to fig. 3, the limit pin 3 is inserted into a through hole formed at the top of the pin cylinder 2, and the cross section of the through hole is stepped, wherein the maximum inner diameter of the through hole is equal to the maximum outer diameter of the limit pin 3.

Referring to fig. 1, the length of the positioning pin 5 is greater than the length of the short groove 7.

Referring to fig. 2, the width of the long groove 4 is equal to the outer diameter of the positioning pin 5.

Be used for connecting fixed base 1, the through-hole that 2 tops of round pin section of thick bamboo were seted up is passed to spacer pin 3, the through-hole is the shoulder hole, the internal diameter of through-hole is by last increase in proper order down, spacer pin 3's shape is the echelonment, its external diameter has down to increase in proper order, the diameter of 3 bottoms of spacer pin equals with the internal diameter of through-hole bottom, make spacer pin 3 only can slide in certain stroke, can't upwards extract round pin section of thick bamboo 2, locating pin 5 card is in 1 long recess 4 of base, prevent that spacer pin 3 from pushing out base 1 downwards.
