Description
Technical field
The utility model is related to teacher's apparatus field, specifically a kind of eject teaching pole.
Background technology
Currently, the longer body of rod of the most body of rod of teaching pole that teacher uses, this teaching pole is since the body of rod is longer, not Portable belt,
Also there is the teaching pole using telescopic rod as the body of rod in the market, but this telescopic rod needs to hold bottom, the other hand on the other hand when in use
Top is held to extract interior bar, and the top of interior bar is easily stained with chalk bits, powder while extracting due to repeatedly touching blackboard
Chip dust can stick to your hands, very unhygienic.
Invention content
The purpose of this utility model is to provide a kind of eject teaching pole.
To achieve the above object, the utility model includes the body of rod, and the inside both sides of the body of rod are provided with identical L-shaped gear
The vertical plate of slot, the L-shaped retaining groove is run through by the snap-on push button through the body of rod, the inner lower of the body of rod by spring I with
Supporting plate connects, and the top of the supporting plate is placed with interior bar, and the outer wall of the interior bar and the inner wall of the body of rod are slidably connected, the interior bar
Lower part both sides be provided with identical retention device, the retention device is made of spring II, limiting plate and groove, described recessed
Slot is arranged on the side wall of interior bar, and the lower part of the groove is connect by axis pin with limiting plate, and the limiting plate passes through spring II
It being connect with the centre position of groove, one end of the limiting plate is against between the angle of L-shaped retaining groove, among the interior bar on the lower
Elastic button is symmetrically arranged on outer wall, the elastic button is matched with the limiting groove of interior bar inner wall both sides.
Preferably, the elastic button is rubber material.
Preferably, being cased with spring III on the snap-on push button outer wall, one end of the spring III and the outer wall of the body of rod connect
It connects, the other end is connect with snap-on push button.
With the above arrangement, the utility model can make the top automatic spring of interior bar, and then avoid because dropping interior bar top
Portion and caused by be infected with the phenomenon that chalk is considered to be worth doing on hand, clean hygiene, the utility model is easy to carry, easy to use.
Description of the drawings
The utility model is described further in conjunction with attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the usage state diagram of the utility model.
In figure：1, the body of rod, 2, L-shaped retaining groove, 3, snap-on push button, 4, spring I, 5, supporting plate, 6, interior bar, 7, retention device, 8,
Spring II, 9, limiting plate, 10, groove, 11, elastic button, 12, limiting groove, 13, spring III.
Specific implementation mode
As shown in Figure 1, 2, the utility model includes the body of rod 1, and the inside both sides of the body of rod 1 are provided with identical L-shaped gear
The vertical plate of slot 2, the L-shaped retaining groove 2 is run through by the snap-on push button 3 through the body of rod 1, and the inner lower of the body of rod 1 passes through bullet
Spring I 4 is connect with supporting plate 5, and the top of the supporting plate 5 is placed with interior bar 6, and the outer wall of the interior bar 6 connects with the inner wall sliding of the body of rod 1
It connects, the lower part both sides of the interior bar 6 are provided with identical retention device 7, and the retention device 7 is by spring II 8, limiting plate 9
It is constituted with groove 10, the groove 10 is arranged on the side wall of interior bar 6, and the lower part of the groove 10 passes through axis pin and limiting plate 9
Connection, the limiting plate 9 are connect by spring II 8 with the centre position of groove 10, and one end of the limiting plate 9 is against L-shaped gear
Between the angle of slot 2, be symmetrically arranged with elastic button 11 on the outer wall among the interior bar 6 on the lower, the elastic button 11 with
The limiting groove 12 of 6 inner wall both sides of interior bar matches.
The elastic button 11 is rubber material.
Spring III 13 is cased on 3 outer wall of the snap-on push button, one end of the spring III 13 is connect with the outer wall of the body of rod 1,
The other end is connect with snap-on push button 3.
With the above arrangement, when the utility model is used, pressing the snap-on push button 3 of both sides simultaneously, snap-on push button 3 can band
Dynamic limiting plate 9 is to 1 medial movement of the body of rod, and after limiting plate 9 is departing from the blocking of L-shaped retaining groove 2, spring I 4 will be sprung back, to
Drive supporting plate 5 and interior bar 6 to move up, the top of interior bar 6 made to pop up the body of rod 1, if the elastic force of spring I 4 is enough, can make elasticity by
Button 11 is stuck in limiting groove 12, if elastic force is inadequate, can be held the centre position of interior bar 6, be pulled up interior bar 6, make elastic button 11
It matches, can use with limiting groove 12, effectively avoid being infected with chalk bits on hand caused by due to dropping at the top of interior bar
Phenomenon occurs, and the utility model elastic button 11 is rubber material, has good retractility, so when dropping interior bar,
Elastic button 11 can be compressed first, and after reaching limiting groove 12, size before will reverting to is stuck in limiting groove 12
It is interior, facilitate teacher to use.
