Abstract

The utility model comprises an inner pipe 2, an outer pipe 8 and a connecting base 3, wherein small holes 11 are arranged on the inner pipe at intervals. The inner column surface of one end of the connecting base is tightly matched and fixedly connected with the outer pipe. The other end of the connecting base is freely sheathed in a gap of the inner pipe. The connecting base comprises a base body 3, a button rod 5, a button 6, a pin shaft 4, a steel ball 10 and a spring 7. The button rod is arranged in a groove of the connecting base body and is connected with the groove by the pin shaft. The steel ball is arranged in a blind hole near the front end of the button rod, the spring is arranged in the other blind hole of the button rod, and the button and a square column at the tail of the button rod are in clearance fit by a square hole. The steel ball in the connecting base is matched with the small holes on the inner pipe. The front end of the inner pipe is connected with an outer thread joint 1 which can be connected to other tools. The tail end of the outer pipe is sheathed with a soft gum handle 9, and a hand feels comfortable during construction and operation. The inner pipe of the utility model is an octagon aluminum pipe, and the outer pipe is a circular aluminum pipe or a glass fiber pipe. The utility model is light and convenient to operate and carry, and can be pulled and shrunk freely; the joint assembled with different tools can carry out various operations.

Description

Moving button expansion link

Technical field

The utility model belongs to a kind of handle of instrument, by flexible its adjustable length between two bars.

Background technology

Many handworks such as cleaning and whitewashing jewelry, are used long handle sometimes, use short handle sometimes, need often to change handle or spreading handle, and are easy to carry when knocking off, and also will take apart and deposit, and the workman uses very inconvenient.

Summary of the invention

The purpose of this utility model provides a kind of bar that has retractor device, can elongate and shorten, and is easy to use.

The utility model comprises interior pipe, outer tube and connection seat, has aperture at interval on the interior pipe, and connection seat one end inner cylinder and outer tube close-fitting connect firmly, the empty cover of the connection seat other end and interior ligament; Connection seat comprises pedestal, button spindle, button, bearing pin, steel ball and spring, button spindle is put into connection seat pedestal chamber groove and is connected with bearing pin, steel ball is put into forward end one blind hole of button spindle, and spring is put into another blind hole of button spindle, and button is by square hole and button spindle tail square column matched in clearance; Steel ball in the connection seat matches with aperture on the interior pipe.

Front end at interior pipe is associated with a male connection, can link with other instrument; In the tail end socket flexible glue handle of outer tube, comfortable feel during constructing operation.

Pipe is anistree aluminum pipe in of the present utility model, and outer tube is circle aluminum pipe or fiberglass tubes.Lightly be convenient to operate and carry, can freely stretch and shrink, the instrument that the joint assembling is different can carry out several work, and is of many uses.

Description of drawings

Fig. 1 is a stereogram of the present utility model;

Fig. 2 is the stereogram of each parts of the utility model, shows its structure composition;

Fig. 3 is the partial sectional view of confined state of the present utility model.

The specific embodiment

Now in conjunction with the accompanying drawings, the specific embodiment of the present utility model is described below:

As shown in Figure 3, by moving button grip assembly aluminum pipe 2 in anistree is connected into glass outer tube 8 and can tightens up telescopic product.

As shown in Figure 1, anistree aluminum pipe 2 front ends are associated with external screw thread head 1, can with other instrument, join as roller shelves, but glass outer tube 8 tail end socket flexible glue handles 9, comfortable feel during constructing operation

Shown in Fig. 2 and 3, connection seat 3 one end inner cylinder and glass outer tube 8 close-fittings connect firmly, the empty cover in aluminum pipe 2 gaps in anistree hole of the other end and the foraminate anise of axial zone, button spindle 5 is put into connection seat 3 chamber grooves and is connected two parts with bearing pin 4, steel ball 10 is put into forward end one blind hole of button spindle, stage clip 7 is put into another blind hole of button spindle, and button 6 is by square hole and button spindle 5 tail square column matched in clearance.When button 6 slides into button spindle 5 tail end positions, button 6 bottom surfaces and connection seat 3 chamber groove step surfaces are thrown off, aluminum pipe 2 can easily spur forward in anistree, if steel ball 10 just snap in anistree on the aluminum pipe 2 in the aperture 11, then can not make the pressure that acts on the steel ball 10 overcome spring pressure and jump out anistree on the aluminum pipe 2 aperture 11 to making aluminum pipe drop-down, if but pressed the button 6, at this moment anistree interior 2 of aluminum pipes could spur up and down freely; Promote button 6 forward and make it bottom surface and connection seat 3 step surfaces and fit, steel ball 10 be locked in anistree in aluminum pipe 2 apertures 11, at this moment the upper and lower stretchies not of aluminum pipe are integral inside and outside the connecting firmly of expansion link.
