Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example one

Referring to fig. 1-2, a multipurpose telescopic rod without punching comprises an outer tube 1, a sleeve 2 is sleeved in the outer tube 1, a spring 3 is fixedly connected in the sleeve 2, and two ends of the spring 3 are dead springs.

The utility model discloses in, all seted up the pinhole on outer tube 1 and the sleeve pipe 2, fixedly connected with rivet 7 on the outer tube 1, rivet 7 run through the pinhole and contact with spring 3.

The utility model discloses in, fixedly connected with sealing plug 4 is all sealed at the both ends of sleeve pipe 2, one side fixedly connected with base 5 of sealing plug 4, one side fixedly connected with slipmat 6 of base 5.

Example two

Referring to fig. 1-2, a multipurpose telescopic rod without punching comprises an outer tube 1, a sleeve 2 is sleeved in the outer tube 1, a spring 3 is connected in the sleeve 2 through a rivet, springs 3 are tightly contracted at two ends of the spring 3, the diameter of the outer tube 1 is 25mm, the diameter of the inner tube 2 is 22mm, two ends of the spring 3 are in a tightly contracted state, the spring 3 can be prevented from being pulled out by the rivet 7, the sleeve 2 can be sleeved in the outer tube 1 due to the arrangement of the outer tube 1 and the sleeve 2, the spring 3 is placed in the sleeve 2, one end of the spring 3 is fixed at one end of the sleeve 2 through the rivet 7, when the spring 3 is pulled, the rivet 7 can rotate along wires of the spring 3, the sleeve 2 can be pulled out, the spring 3 cannot be pulled out due to the tight contraction at two ends of the spring 3, and the purpose of the sleeve 2 can be achieved, due to the arrangement of a base 5, the spring 3 can be, non-slip mat 6 can play the antiskid effect, make this device can be more firm fix on the wall, the utility model discloses simple structure, through outside pulling spring, can make the rivet rotate along the spring orbit, and then can make the sleeve pipe roll out, reach flexible purpose, convenient and fast, complex operation's problem in the past has been solved, because the both ends of spring are for contracting the dead state, so the rivet is when the spring internal rotation, can not pull out the spring, and then guaranteed that the sheathed tube is flexible, when the sleeve pipe extends to suitable position, through compression spring, just can be on the wall with the base top, need not punch, just can fix this device on the wall, and fixed fastness is stronger.
