Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-3, a anticreep extension spring, including extension spring body 1, extension spring body 1's both ends integrated into one piece has extension arm 2, extension arm 2's one end integrated into one piece has drag hook 3, drag hook 3's design, so as to the hanging of object, drag hook 3's one end is equipped with the recess, one side of recess is rotated and is connected with rotation cardboard 4, one side of drag hook 3 is equipped with perforation 5, it pegs graft mutually with perforation 5 to rotate cardboard 4, and one side of rotating cardboard 4 is equipped with the screw hole, screw hole female connection has set screw 6, rotate cardboard 4, the design of mutually supporting between perforation 5 and the set screw 6, can fix rotation cardboard 4, the problem that drops easily in the use has been solved effectively, the availability factor of extension spring body 1 has been improved.
Wherein, one side of the extension arm 2 is sleeved with a sliding sleeve 7, the sliding sleeve 7 can be manually pushed by the design of the sliding sleeve 7, so that the sliding sleeve 7 slides on one side of the extension arm 2, and plug up perforation 5, avoid the dust to fall into in perforation 5, prevent that the dust from causing the jam to perforation 5, the result of use of device has been improved, extension spring body 1, the rubber sleeve has all been bonded to one side of extension arm 2 and drag hook 3, the joining of rubber sleeve, can increase the frictional force of 1 extension arm 2 of extension spring body and drag hook 3, the both sides integrated into one piece of drag hook 3 has rubber block 9, one side of drag hook 3 is equipped with a plurality of antiskid groove 8, antiskid groove 8 and rubber block 9's design, can further block drag hook 3, effectually avoid the object to break away from with drag hook 3 mutually, the practicality of extension spring body 1 has been improved, drag hook 3 is the loop configuration, antiskid groove is the bar knot, it is the arc structure to rotate the cardboard.
