Abstract
The utility model discloses a telescopic pipe for an electric tool, which comprises an outer pipe, an inner pipe which is inserted into the outer pipe, and a plastic jacket which is fixed inside the end part of the inner pipe, wherein the inner pipe and the outer pipe are connected and fixed with each other through a locking sleeve and are limited by limit stops which are movably connected with the plastic jacket. Therefore, the telescopic pipe for the electric tool has the function of stretching and limiting, and the two pipes can not be pulled out and fallen off due to overlarge force exerted.
Description
Technical field
The utility model relates to a kind of electric tool, especially a kind of telescoping tube of electric tool.
Background technology
In the prior art, electric tool adopts tube connector to connect usually, and these electric tools can be grass-mowing machine, bar chain saw, bar shrub and hedge trimmer etc.Some telescoping tubes adopt and are threaded, but can not realize stretch function, and some telescoping tube adopts cam structure to connect, but inner and outer pipes can not realize splitting the requirement that reaches the saving packaging material.Create a kind of telescoping tube in recent years again and substitute long pipe, the length of telescoping tube can be regulated according to user's needs, so more convenient to use.Telescoping tube is made up of outer tube and interior pipe, interior pipe is flexible in outer tube, thereby reach the purpose of regulating length, the end of outer tube is fixed with lock sleeve, but telescoping tube is extracted easily in flexible and is come off, because not having of outer tube and interior pipe is spacing, so when flexible when firmly big, outer tube and interior pipe just come off easily.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of limited block of electric tool telescoping tube is provided, and this limited block makes outer tube and interior pipe difficult drop-off when flexible of telescoping tube.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of telescoping tube of electric tool, comprise outer tube, insert interior pipe in the outer tube, be fixed on the plastic sheath of inner tube portion inboard, described interior pipe is connected by lock sleeve with outer tube and is fixing, described interior pipe and described outer tube are undertaken spacing by limited block, this limited block and described plastic sheath flexibly connect.
Described plastic sheath is provided with flexible member, and this flexible member is fixedlyed connected with limited block, for described limited block provides restoring force.
Described outer tube end and lock sleeve junction are provided with quoit, and the interior circular diameter of this quoit is at least greater than the outside diameter of interior pipe.
Described limited block moves along the axis direction perpendicular to pipe in described.
The outer tube end that contacts with described limited block is provided with guiding surface.
Pipe is a non-round tube with described outer tube in described.
The beneficial effects of the utility model are that the utility model is provided with limited block on inner pipe, has played good position-limiting action, can not come off because of excessive two pipes are extracted of exerting oneself.The utility model is simple in structure, and is easy to make.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a cutaway view of the present utility model.
Wherein: 1, outer tube, 2, interior pipe, 3, plastic sheath, 4, lock sleeve, 5, limited block, 6, flexible member, 7, quoit, 8, guiding surface, 9, groove, X, axis.
The specific embodiment
Shown in Fig. 1-2, a kind of telescoping tube of electric tool, comprise outer tube 1, insert the interior interior pipe 2 of outer tube, be fixed on interior plastic sheath 3 of managing inboard, 2 end, pipe 2 is connected by lock sleeve 4 with outer tube 1 and fixes in described, described interior pipe 2 and described outer tube 1 are undertaken spacing by limited block 5, this limited block 5 flexibly connects with described plastic sheath 4.Described plastic sheath 3 has groove 9, when limited block is extruded, this groove 9 is used to hold limited block, described plastic sheath 3 is provided with flexible member 6, this flexible member 6 can be spring leaf, this flexible member 6 is fixedlyed connected with limited block 5, for described limited block 5 provides restoring force, described outer tube 1 end and lock sleeve 4 junctions are provided with quoit 7, at least greater than the outside diameter of interior pipe, outer tube 1 end that contacts with described limited block 5 is provided with guiding surface 8 to the interior circular diameter of this quoit 7.This electric tool can be grass-mowing machine, bar chain saw, bar shrub and hedge trimmer etc.Pipe is a non-round tube with described outer tube in described.
When the operator stretches telescoping tube, at first limited block 5 contacts with guiding surface 8, because limited block 5 is subjected to the pressure of guiding surface 8, make flexible member 6 compressive deformations that are arranged on the limited block 5, limited block 5 moves down along vertical axis X, pipe 2 and outer tube 1 is flexible in interior pipe 2 can relatively move with outer tube 1, realize.In addition, when interior pipe 2 was stretched to extreme position with respect to outer tube 1, limited block 5 collided the lock sleeve 4 to outer tube 1, because lock sleeve 4 is a working of plastics, intensity is not high, so increased quoit 7 at the position of collision place.
