The technical scheme that its technical problem that solves the utility model adopts is: a kind of telescoping tube of electric tool, the cover that is locked that comprises outer tube, inserts interior pipe in the described outer tube, is locked and is connected with described interior pipe, this telescoping tube also comprises fixed cover, described fixed cover and the described cover one end engagement connection that is locked, and described fixed cover and described outer tube engagement connection.
According to another embodiment of the present utility model, telescoping tube further comprises having a right-hand thread on the described fixed cover at least, has two grooves on the described outer tube at least, and described right-hand thread snaps in described groove and keeps outer tube to fixedly connected with fixed cover.
According to another embodiment of the present utility model, telescoping tube further comprises the stopper slot that has on the described cover inwall that is locked along axis direction, and described right-hand thread is moved in described stopper slot vertically.
According to another embodiment of the present utility model, telescoping tube further comprises and is provided with a left-hand thread on the described fixed cover at least, at least be provided with and the corresponding boss of left-hand thread on the described cover inwall that is locked, will be locked by left-hand thread and boss and overlap and the fixed cover engagement connection.
According to another embodiment of the present utility model, telescoping tube comprises that further described fixed cover one side is extended with first brace, and described right-hand thread is arranged on the outer surface end of first brace.
According to another embodiment of the present utility model, telescoping tube comprises that further described fixed cover one side is extended with second brace, and outer tube is axially having and the corresponding opening of left-hand thread, and described left-hand thread is arranged on the outer surface end of second brace.
According to another embodiment of the present utility model, telescoping tube further comprises the described cover other end lock sleeve that has been threaded that is locked, and this lock sleeve making the cover that is locked contact locking with inner tube outer surface by the be locked inclined-plane distortion of cover of compressing.
The beneficial effects of the utility model are, the utility model makes the cover that is locked can fix very easily with outer tube by fixed cover, make that like this telescoping tube assembling is simple and convenient, amount of parts obviously reduces, thereby greatly reduce the cost of raw material and labor hour cost, improved competitiveness of product.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the exploded perspective view of the embodiment of the utility model telescoping tube.
Fig. 2 is the cutaway view of the utility model telescoping tube.
Wherein: 1, outer tube, 3, interior pipe, 5, the cover that is locked, 7, fixed cover, 9, right-hand thread, 11, groove, 15, stopper slot, 17, left-hand thread, 19, boss, 21, first brace, 23, second brace, 25, opening, 27, lock sleeve.
The specific embodiment
Shown in Fig. 1-2, a kind of telescoping tube of electric tool, comprise outer tube 1, insert interior pipe 3 in the described outer tube 1, with described in pipe 3 being locked of being connected that be locked overlap 5, cover 5 other ends lock sleeve 27 that has been threaded is locked, this lock sleeve 27 is by compressing cover 5 the inclined-plane distortion that is locked, making the cover 5 that is locked contact locking with interior pipe 3 outer surfaces, this telescoping tube also comprises fixed cover 7, described fixed cover 7 and the described cover 5 one end engagement connections that are locked, and described fixed cover 7 and described outer tube 1 engagement connection.Wherein, has a pair of right-hand thread 9 on the fixed cover 7 at least, have two grooves 11 on the described outer tube 1 at least, described right-hand thread 9 snaps in described groove 11 and keeps outer tube 1 to fixedly connected with fixed cover 7, overlap the stopper slot 15 that has on 5 inwalls along axis direction and be locked, described right-hand thread 9 is moved in described stopper slot 15 vertically.Further fixed cover 7 one sides are extended with first brace 21, and described right-hand thread 9 is arranged on the outer surface end of first brace 21.Described first brace 21 is made for elastomeric material, makes right-hand thread 9 flexiblely to snap in the groove 11.
At least be provided with a left-hand thread 17 on the fixed cover 7, the described cover that is locked is provided with and left-hand thread 17 corresponding boss 19 on 5 inwalls at least, by left-hand thread 17 and boss 19 will be locked cover 5 and fixed cover 7 engagement connections.And fixed cover 7 one sides are extended with second brace 23, axially having and left-hand thread 17 corresponding openings 25 with the outer tube 1 of the link of fixed cover 7, described left-hand thread 17 is arranged on the outer surface end of second brace 23, and wherein, described second brace 23 is made for elastomeric material.
