The utility model discloses further technical scheme is: the stress application rod is made of steel materials.
Effects of the invention
The technical effects of the utility model reside in that: the beneficial effect that this device produced specifically as follows:
(1) the right-angle pull rod is designed, so that the locking mechanism can be clamped by matching with a clamping groove of the locking mechanism before the right-angle pull rod is decomposed, the right-angle pull rod is hinged with the clamp base, the right-angle pull rod is convenient to flexibly align with the clamping groove, and the operation is convenient.
(2) One end of the rotating ejector rod is designed into a concave spherical structure and matched with the outer spherical surface of the locking mechanism pin, so that the rotating ejector rod can reliably transmit axial force during rotation in the decomposition process.
(3) The stress application rod drives the rotary ejector rod to move axially through forward rotation or reverse rotation, so that the tension of the spring is overcome, the locking mechanism is far away from the notch of the outer barrel, and the disassembly is convenient.
To sum up, the utility model is simple in operation convenient, reduce the degree of difficulty when locking mechanism decomposes, assembles, practiced thrift the repair expense, improved work efficiency greatly.

Detailed Description
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention.
Referring to fig. 1-3, the "locking mechanism disassembly special fixture" includes four parts, namely 1 rotating top rod, 1 fixture base, 1 stressing rod and two pull rods.
Because the head of the pin of the undercarriage locking mechanism is a spherical surface, in order to prevent the rotating ejector rod from slipping when the locking mechanism is disassembled by using the clamp, a spherical surface matched with the rotating ejector rod is designed at one end of the rotating ejector rod combined with the head of the undercarriage, the outer wall of the end is provided with a common fine thread external thread, the other end is provided with a phi 10mm through hole, and the axis of the through hole is superposed with the axis of the rotating ejector rod.
The center of the bottom of the clamp is provided with an internal thread and two bulges.
The stress application rod is a steel bar with the diameter phi of 10 mm.
The pull rod is a 90-degree pull rod.
The hook end of the clamp is hooked on the two notches of the upper barrel through the two hinged right-angle pull rods, then the force applying rod is rotated to enable the inner spherical surface of the rotating ejector rod to be matched with the outer spherical surface of the pin of the locking mechanism, meanwhile, the pin of the locking mechanism is compressed by overcoming the tension of the spring, so that the stud of the locking mechanism is driven to move downwards, the fork bolt of the locking mechanism is separated from a narrow closed area at the upper part of the upper barrel, when the fork joint moves to the notch of the upper barrel, the fork joint can be reversely screwed by a hand or a small rod, the T-shaped joint is easily screwed down, and the fork joint is taken down. And then reversely screwing the rotary stress application rod, dismounting the stud and taking down the pin and the cylindrical spring.
