The technical scheme adopted by the utility model is as follows:

the special tool for disassembling the pin shaft of the buffer sleeve comprises a U-shaped equipment rack and the pin shaft arranged in the U-shaped equipment rack, wherein the pin shaft is sleeved in a buffer sleeve, and a pulling hand is sleeved outside the buffer sleeve; the opening of the U-shaped ejection rack is arranged upwards, the opening of the U-shaped equipment rack is arranged downwards, one side of the opening of the U-shaped ejection rack is arranged in a space between the handle and the U-shaped equipment rack, and one side of the opening of the U-shaped ejection rack is abutted against one side of the opening of the U-shaped equipment rack;

a U-shaped groove is formed in one side, close to the U-shaped equipment rack, of the U-shaped ejection rack, an internally threaded through hole for an ejection bolt to pass through is formed in the other side of the U-shaped ejection rack, and the internally threaded through hole is opposite to the penetrating opening and the U-shaped groove;

the ejection bolt is provided with a fine tooth external thread which is matched with the through hole with the internal thread.

Further, the central point connecting lines of the top outlet, the penetrating opening and the through hole with the internal thread are positioned on the same straight line.

Compared with the prior art, the utility model has the beneficial effects that:

1. when the utility model is applied, the quick disassembly of the buffer sleeve pin shaft of the smoke machine equipment can be realized, and the condition of low efficiency of hammer, copper bar knocking and the like which are needed in the traditional maintenance work is changed.

2. The portable special tool for disassembling the buffer sleeve pin shaft of the smoke machine equipment has the advantages of simple structure and high reliability.

Detailed Description

The following describes the detailed implementation of the embodiments of the present utility model with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other.

The utility model will be described in detail below with reference to the drawings in connection with exemplary embodiments.

Referring to fig. 1 to 3b, the special tool for disassembling a buffer sleeve pin shaft of the utility model comprises a U-shaped equipment rack 3 and a pin shaft 5 arranged in the U-shaped equipment rack 3, wherein the pin shaft 5 is sleeved in a buffer sleeve 6, a pulling hand 4 is sleeved outside the buffer sleeve 6, the special tool also comprises a U-shaped ejection rack 2 and an ejection bolt 1, and a top outlet for ejecting the pin shaft 5 and a penetrating opening for penetrating the ejection bolt 1 are respectively arranged at positions, corresponding to the front end and the rear end of the pin shaft 5, of two sides of the U-shaped equipment rack 3; the opening of the U-shaped ejection rack 2 is arranged upwards, the opening of the U-shaped equipment rack 3 is arranged downwards, one side of the opening of the U-shaped ejection rack 2 is arranged in a space between the handle 4 and the U-shaped equipment rack 3, and one side of the opening of the U-shaped ejection rack 2 is abutted against one side of the opening of the U-shaped equipment rack 3;
