Problems solved by technology

[0004] The push ring 94 of the above-mentioned connecting rod is combined with the clamping rod 92 through the latch 93. By pushing the push ring 94 to move the clamping rod 92, the steel ball is controlled to fall downward and the sleeve is removed, and it can be judged by its manual and diagram , the above-mentioned connecting rod needs to push the push ring 94 to make the steel ball drop down to install the sleeve, but such an operation action is not easy to control, the operator must hold the main body 91 with one hand, and hold the push ring 94 with the other hand , at this time, the operator has no hand to hold the sleeve, or the operator needs to manipulate the main body 91 and the push ring 94 with one hand at the same time, while holding the sleeve with the other hand, and place the sleeve on the square column , such an operation method is quite unsmooth, and has the defect that it is not easy to operate, and cannot achieve the purpose of quickly installing the sleeve

Abstract

The invention discloses an extension rod capable of fast pulling and loosing a sleeve, belonging to the technical field of extension rods. The extension rod comprises a rod body, a first elastic piece, a clamping rod, a second elastic piece and an external member. The user can hold the rod body by one hand, and place the sleeve around a bearing section of the rod body by the other hand, so as to enable the extension rod to pull the sleeve fast; or the user can hold the rod body by one hand, then hold and move the external member by the other hand, so as to enable the extension rod to loose the sleeve fast.

Description

technical field [0001] The invention relates to a post, in particular to a post that can be taken and placed quickly. Background technique [0002] The post-type hand tool is endowed with diversified usability because it can accept different styles of screwdriver bits. [0003] see Figure 13 , is a schematic diagram of a known anti-off quick connector of a wrench. The anti-off quick connecting rod includes a body 91, a clamping rod 92, a latch 93, a push ring 94 and a spring 95; The elongated through hole of 91 and the through hole of clamping rod 92 combine the above structures, so that when the user pulls the push ring 94 backward, the clamping rod 92 can be moved backward through the latch 93 , when the clamping rod 92 moved backward, the annular groove on it also moved backward, so that the steel ball fell downwards, and the sleeve could be quickly and easily removed. [0004] The push ring 94 of the above-mentioned connecting rod is combined with the clamping rod 92...
