Abstract

The invention discloses a multipurpose self-locking quick release device. The multipurpose self-locking quick release device comprises a first butt joint block and a second butt joint block, a through hole is formed in the first butt joint block in the length direction of the first butt joint block, an ejector rod is coaxially arranged in the through hole, the length of the ejector rod is larger than that of the through hole, and the two ends of the ejector rod can stretch out of the two ends of the first butt joint block; a clamping groove is formed in the second butt joint block, a clamping block is arranged at the end, right opposite to the clamping groove, of the ejector rod, the clamping block can be inserted into the clamping groove, after the ejector rod rotates by a certain angle around the axis of the ejector rod, the clamping block can be connected with the clamping groove in a clamped mode; the ejector rod is sleeved with a spring, one end of the spring is fixed to the first butt joint block, the other end of the spring is fixed to the ejector rod, and the clamping block can be locked in the clamping groove under the action of the spring; an auxiliary locking structure is further arranged at the end, away from the second butt joint block, of the first butt joint block and can prevent the ejector rod from rotating around the axis of the ejector rod when the ejector rod is locked in the clamping groove.

Description

technical field [0001] The invention relates to a quick-release structure of a portable probe, in particular to a multi-purpose self-locking quick-release device. Background technique [0002] Most of the existing quick plug-in joints adopt an elastic structure, through which the elastic member can pop into the card slot during quick connection to realize quick installation, but when dismounting, it is necessary to overcome the elastic force of the spring to disassemble it. It is disconnected, and after locking, it is easy to squeeze or turn and fall off, the connection is unreliable, and it is inconvenient to use. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: to provide a portable probe for the assembly of the extension rod, which can realize the quick connection of the portable probe and the extension rod, and can solve the problems of self-locking and rotati...
