An external rotary puller pen

Abstract

An external rotary pulling-connecting pen, comprising a front pen holder device (1) and a rear pen holder (2), wherein the rear pen holder (2) is movably sleeved on an end outside of the front pen holder device (1); the front pen holder device (1) comprises a pen head (101) and a sleeve spine (102), and the sleeve spine (102) is fixedly connected to the rear end of the pen head (101); a buckle protruding inward is fixed to the inner side of the rear pen holder (2); a locking fixing slot (103) is formed in the outer part of the sleeve spine (102); a return slope (104) is formed on the side wall of the locking fixing slot (103); a pair of isolating flow-dividing plates (105) are provided on the outside of the sleeve spine (102); a guiding movable channel is formed between the pair of isolating flow-dividing plates (105); and an auxiliary buckle (106) is fixedly connected to one end of the isolating flow-dividing plates (105). In the described external rotary pulling-connection pen, the use state and a non-use state of a fixed buckle may be positioned by means of the locking fixing slot and a fixed blocking slot, so that stability of the device is improved. The locking fixing slot and the auxiliary buckle match each other so that position guiding is performed on the fixed buckle, thereby improving the convenience of the device.

Description

technical field [0001] The invention relates to the technical field of office appliances, in particular to an external rotary extension pen. Background technique [0002] With the continuous progress of society, people's desire for cultural knowledge is increasing day by day.
