Embodiment Construction
[0013] As shown in the figure, the wire protection tube opener is composed of a support ring 3, an opening cone 5 and a handle 2, the handle 2 is a "7" cantilever type, the support ring 3 is a notched ring, and the opening cone 5 It is a ">" shape with a large top and a small bottom. The opening of the opening cone 5 and the gap of the support ring 3 are welded and fixed. The support ring 3 and the opening cone 5 form a side "U"-shaped double-walled ring in the top view. The opening cone 5 The height is greater than the height of the support ring 3, and the upper end of the opening pointed cone 5 is flush with the upper end of the support ring 3.
[0014] A large roller 4 is rotatably fixed on both sides of the opening cone 5 , and a small roller 6 is rotatably fixed on the inner wall of the support ring 3 .
[0015] The section shape of the handle 2 is rectangular, and the vertical section of the handle 2 is clamped in the wooden insulating board 1 .

The invention discloses a wire protection pipe opener, which is composed of a support ring (3), an opening cone (5) and a handle (2). The handle (2) is a "7" cantilever type, and the support ring (3) ) is a notched ring, and the opening cone (5) is in the shape of ">" with a large top and a small bottom. The opening of the opening cone (5) is welded to the gap of the support ring (3), and the support ring (3) and the opening The cone (5) forms a side "U"-shaped double-walled ring in the top view, the height of the open cone (5) is greater than the height of the support ring (3), and the upper end of the open cone (5) is level with the upper end of the support ring (3) together. Compared with the prior art, the present invention can be completed by one person alone, which saves manpower and labor, and does not damage the pull wire sheath. It only takes 10 seconds to replace a set of pull wires. The staff's hand is on the wooden insulating handle, which does not waste time and effort. The prying action will not scratch your hands.
Description
Technical field [0001] The present invention involves a kind of electrician tool, especially a stretching tube open tube. Background technique [0002] The material of the pulling cover is made of hard plastic. The texture is very hard. It is difficult to be separated by the pull -ups during installation.At present, workers often use their hands to stab or use pliers.It is easy to damage the pull -up cover, and it takes time and effort to scratch the hands. The two people need to cooperate with the construction. According to statistics, it takes about 10 minutes to replace a set of stretch.The tube is a technical problem that needs to be solved. Invention content [0003] The technical problem to be solved by the present invention is to provide an open tube of a line -pull tube. [0004] The technical solution of the present invention solves its technical problems is: [0005] The open tube of the pull -up tube is composed of the support ring, the opening of the opening and the ...
