Abstract

The invention discloses a quick assembly disengaging device. Two kinds of parts, namely a bolt and cylinders are assembled on a standard crowbar; and by a self-locking principle, one cylinder is fixed and the other cylinder is used as a peening hammer to form the disengaging device. The disengaging device has the function of the crowbar, becomes the disengaging device once assembled, and can disengage on special parts which cannot be excessively disturbed or have narrow spaces, wherein one cylinder is a metal cylinder, the middle of the cylinder is provided with a taper hole having a larger end and a smaller end, the slope of the taper is kept consistent with the slope of the bolt, a self-locking angle can be reached, and after the cylinder is sleeved in the crowbar, the bolt is inserted into a gap formed between the larger hole and the crowbar, and a stress body is formed after the bolt is tightly knocked; and the other cylinder is used as the peening hammer and moves along the crowbar vertically for peening.

Description

Technical field [0001] The invention belongs to the category of tools. It is used in rescue sites where large machinery, electric and pneumatic tools are inconvenient to operate. Background technique [0002] On May 12, 2008, a major earthquake occurred in Wenchuan. A large number of houses collapsed, lives and property suffered heavy losses, and a large number of people were buried under the ruins. A large number of buried people were rescued with simple tools such as shovels, shovels, etc. Because large machinery could not be used, some soldiers even ground their hands to the bone... Sometimes it was only because of a prefabricated board that the precious rescue time was delayed. From this, I came up with the idea of ​​inventing a simple and efficient rescue tool for soldiers - quick release device. Contents of the invention [0003] The quick-loading demolition device is assembled on a standard crowbar with two parts - the latch and the cylinder. Using the self-lockin...
