The described bar 1 that swims is two sections different cylinders of thickness, and two sections cylindrical length ratios are 1: 5～1: 8, and diameter ratio is 1: 1.5～1: 3, and it is flat that butt end is provided with milling of fixing mobile chela 4, mills the through hole that flat centre is a mounting screw.

The chela taper ratio of described fixedly chela 3 is 3: 5～3: 7, and base is consistent with the flat width of milling of bar 1 that swims.

Described fixedly chela 3 is made for stainless steel.

Described mobile chela 4 is made for stainless steel.

Beneficial effect

The expansion tool of a kind of heat-shrink tube that the utility model proposes, the difficulty when having changed the expansion of traditional use nipper plier reduces the spoilage of pliers, this instrument is pulled forcing press in conjunction with hand and is expanded simultaneously, time saving and energy saving, effectively alleviated working strength of workers, improved operating efficiency.

The specific embodiment

Now in conjunction with the embodiments, accompanying drawing is further described the utility model:

Fig. 4 is housing 2 structural representations among the utility model embodiment, and housing 2 is the tetragonal body of a middle cylindrical hole, and left end has two to install and fix chela 3 steps and screwed hole is installed, and has opening groove, end face that the installing hole of mounting seat 6 is arranged in the middle of the right-hand member;

Fig. 7 is base 6 structural representations among the utility model embodiment, and floor manufacture has the stepped hole of mounting screw 7;

Fig. 9 is bar 1 structural representation that swims among the utility model embodiment, and left end has one to being equipped with mobile chela 4 tapped through holes of installation above flat; The bar 1 that swims is two sections different cylinders of thickness, and two sections cylindrical length ratios are 1: 5, and diameter ratio is 1: 1.5, and it is flat that butt end is provided with milling of fixing mobile chela 4, mills the through hole that flat centre is a mounting screw.
