The beneficial effects of the utility model are that can come adjust commander's body of rod apart from the distance of show board according to actual conditions, satisfy different situation's needs, it is more convenient, the life of this teaching aid has been improved when reducing its area occupied that prevents the desk, drawing part that the more audio -visual mr of seeing of student of being convenient for need teach.
Description
Technical field
This utility model belongs to teaching aid technical field, especially relates to a kind of teaching aid for machinery course teaching.
Background technology
On classroom especially when mechanical courses, for the more vivid relation given expression between each mechanical drawing, teacher often places it on Graphic Panel, then commander's contrast shows student, so teacher is while needing to take notes on blackboard, while needing point on Graphic Panel to the position needed, to bring trouble to teachers' instruction.Existing employing commands bar, but cannot regulate its command jurisdiction, directly reduces its utilization rate；Commander's bar is straight up and down, due to the student visual angle from different angles, blocks some positions of mechanical drawing sometimes, directly affects the quality that student listens to the teacher.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in construction, suitably can regulate according to practical situation its length and prevent its block the phenomenon at some positions of mechanical drawing occur, improve student listen to the teacher quality for machinery course teaching teaching aid, be especially suitable on classroom in the teaching needing to show various figure.
nullThe technical solution of the utility model is: a kind of teaching aid for machinery course teaching，Including commander's body of rod、Connector、Handle and placing piece，Described commander's body of rod includes brace、And the straight-bar being connected with brace one end，The other end at brace is provided with projection，Described connector left side wall is provided with through hole，The other end of described straight-bar enters in connector from through hole，And the straight-bar end being located in connector is vertically connected with baffle plate，Described baffle plate opposite side is located on the right side wall in connector by compression spring，The upper side wall of connector is provided with multiple adjustment hole，Bolt passes adjustment hole，And withstand on straight-bar，Handle it is provided with outside the right side wall of connector，It is provided with screwed hole at handle opposite side，Described placing piece includes screw、Pulling force rope and round buckle，Described screw is located in screwed hole，Opposite side at screw is connected with round buckle by pulling force rope.
Further, in 120 °～180 ° between described straight-bar and brace.
Further, the length of described baffle plate is longer than the diameter of through hole.
Further, described connector is cuboid, and is cavity in connector.
Further, described handle outer surface is provided with anti-slip veins.
This utility model has the advantage that with good effect: owing to using technique scheme, can regulate the distance of commander's body of rod distance Graphic Panel according to practical situation, meet the needs of different situations, convenient；The service life of this teaching aid is improve, it is simple to student sees that teacher needs the drawing part taught more intuitively while reducing its area occupied preventing desk.

Detailed description of the invention
nullAs shown in Figure 1，The technical solution of the utility model is: a kind of teaching aid for machinery course teaching，Including commander's body of rod、Connector 1、Handle 2 and placing piece，Described commander's body of rod includes brace 3、And the straight-bar 4 being connected with brace 3 one end，The other end at brace 3 is provided with protruding 5，This projection 5 is for reducing the area of section of commander's body of rod and the mechanical drawing on Graphic Panel，It is easy to student and sees that teacher needs the drawing part taught more intuitively，Described connector 1 left side wall is provided with through hole，The other end of described straight-bar 4 enters in connector 1 from through hole，And straight-bar 4 end being located in connector 1 is vertically connected with baffle plate 6，Described baffle plate 6 opposite side is located on the right side wall in connector 1 by compression spring 7，The upper side wall of connector 1 is provided with multiple adjustment hole，Bolt 8 is through adjustment hole，And withstand on straight-bar 4，Handle 2 it is provided with outside the right side wall of connector 1，It is provided with screwed hole at handle 2 opposite side，Described placing piece includes screw 9、Pulling force rope 10 and round buckle 11，Described screw 9 is located in screwed hole，Opposite side at screw 9 is connected with round buckle 11 by pulling force rope 10.
In the present embodiment, in 120 °～180 ° between described straight-bar 4 and brace 3.
In the present embodiment, the length of described baffle plate 6 is longer than the diameter of through hole, it is ensured that straight-bar 4 regulation time without departing from connector 1.
In the present embodiment, described connector 1 is cuboid, and is cavity in connector 1.
In the present embodiment, described handle 2 outer surface is provided with anti-slip veins.
The work process of the present embodiment and principle: during use, the distance of commander's body of rod distance Graphic Panel can be regulated according to practical situation, meet the needs of different situations, after unclamping bolt 8, baffle plate 6 on straight-bar 4, owing to being connected with compression spring 7, now can be directed away from handle 2 side shifting automatically, after straight-bar 4 moves to the position needed, bolt 8 is fixed at the adjustment hole on connector 1, the opereating specification of regulation commander's body of rod can be realized；At handle 2 tail, it is provided with placing piece, when inapplicable teaching aid, its round buckle 11 is at will hung on the hook of blackboard side, while reducing its area occupied preventing desk, improve the service life of this teaching aid.
Above an embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model.All impartial changes made according to this utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
