Problems solved by technology

[0002] At present, the traditional pull pin does not have a locking and positioning structure design. When in use, the pull pin is often kept stuck in the pin hole due to the action of the spring, and cannot be fixed in the locked or unlocked state.
When two or more pull pins need to be pulled open at the same time, the pull pins cannot be fixed in the unlocked state one by one, and it is quite inconvenient for a single person to operate; at the same time, the existing pull pins cannot fix the pull pins in the locked state. There are often accidental slippages in the middle, resulting in unexpected situations

Abstract

The invention discloses a pull pin with the locking function. The pull pin comprises an outer sleeve, an inner rod, a spring and a rotary knob; a spring limiting choke is arranged at the upper end ofthe outer sleeve; a spring clamping part is arranged on the inner rod; the spring is arranged on the inner rod in a sleeving manner; the spring and the inner rod are inserted in the outer sleeve together, so that one end of the spring is propped against the spring limiting choke, and the other end of the spring is propped against the spring clamping part; the outer side of the inner rod is connected with the rotary knob; and a chuck is arranged at the inner side end of the inner rod. Compared with the prior art, the pull pin has the following advantages: the pull pin can realize the locking function in the unlocking state and can simultaneously open two or more zippers, and at the same time, the pull pin can be fixed in the locking state to effectively prevent accidental slip.

Description

technical field [0001] The invention relates to a pull pin, in particular to a pull pin with a locking function. Background technique [0002] At present, the traditional pull pin does not have a locking and positioning structure design. When in use, the pull pin is often kept stuck in the pin hole due to the action of the spring, and cannot be fixed in the locked or unlocked state. When two or more pull pins need to be pulled open at the same time, the pull pins cannot be fixed in the unlocked state one by one, and it is quite inconvenient for a single person to operate; at the same time, the existing pull pins cannot fix the pull pins in the locked state. There are often accidental slippages in the middle, resulting in unexpected situations. Therefore, developing a pull pin with a locking function has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0003] The present invention aims to solve the above disadvantages, and pro...
