It is very little to be equal.
Preferably, the baffle link slot is externally provided with projection baffle, and projecting baffle is " T " shape structure.
Preferably, the projection baffle is metal material, and projects baffle surface and be coated with pigment.
Preferably, the connecting column is spiral rod structure, and the axis of connecting column and fixed cone is perpendicular with fixed fastener
It is overlapped to bisector.
Compared with prior art, the utility model has the beneficial effects that the PE testing long-jump index device both can be with
It enables student intuitively see distance versus, and can remain clear.The fixing card of this PE testing long-jump index device
Part can be inserted among the soil by sand pit by connecting column and baffle link slot and is fixed, because being fixed with cylinder in fixed fastener
Laser pen swashs so cylinder laser pen, which may be at one end outside sand pit, sets the other end to sand pit for laser beam to enable
Light is in right above sand pit, and the fine sand displacement to enable student that can intuitively see distance versus, and in sand pit will not be to sharp
Light impacts.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of PE testing long-jump index device, packet
Fixed fastener 1 is included, fixed fastener 1 is " C " shape structure, and the radian of fixed fastener 1 is not less than 300 °, and fixed fastener 1 is elasticity
Plastic material, this structure allow fixed fastener 1 to carry out elastic deformation to change the openings of sizes of itself, facilitate fixed cylinder
Laser pen 2, and 1 radian of fixed fastener is larger, enables cylinder laser pen 2 not fall off inside fixed fastener 1, in fixed fastener 1
It is connected with cylinder laser pen 2,1 outer wall of fixed fastener is connected with connecting column 5, and 5 bottom end of connecting column is equipped with fixed cone 3, connection
Column 5 is spiral rod structure, and the axis of connecting column 5 and fixed cone 3 is overlapped with the vertical bisector of fixed fastener 1, this structure
So that connecting column 5 needs to be rotatably inserted among soil, rotation is extracted except soil, enables connecting column 5 that can more stably be fixed on
Inside soil, and fixed fastener 1 be located at 5 two sides of connecting column part size it is identical, to enable the deformation tolerance of 1 two sides of fixed fastener
It will not differ excessive, fixed cone 3 is externally connected to baffle link slot 6, and each size of baffle link slot 6 and each size of fixed cone 3
It is equal, this structure is entrenched in fixed cone 3 firmly inside baffle link slot 6, enables fixed cone 3 that can pass through baffle
Link slot 6 links together with projection baffle 4, convenient to store to the present apparatus, and baffle link slot 6 is externally provided with projection baffle 4,
And projection baffle 4 is " T " shape structure, this structure puts the horizontal component of projection baffle 4 on the ground, enables projection gear
The vertical portion of plate 4 stretches to sky, then the laser that cylinder laser pen 2 generates can be thrown on projection baffle 4, enables cylinder laser pen
2 laser generated will not project too far, and projection baffle 4 is metal material, and project 4 surface of baffle and be coated with pigment, this structure
So that there is projection baffle 4 biggish weight will not topple over easily, and the coating order for projecting 4 surface of baffle is incident upon projection baffle
The laser position on 4 surfaces is more clear, and fixed cone 3 is inverted cone shape structure, this structure enables fixed fastener 1 that can pass through connecting column
5 and baffle link slot 6 be inserted among the soil by sand pit and be fixed, because being fixed with cylinder laser pen 2, institute in fixed fastener 1
It may be at one end outside sand pit with cylinder laser pen 2 and laser beam set into the other end to sand pit, so that laser rays be enabled to be in
Right above sand pit, the fine sand displacement to enable student that can intuitively see distance versus, and in sand pit will not cause laser rays
It influences.
Working principle: when using PE testing long-jump index device, first by fixed cone 3 from baffle link slot 6
Then fixed fastener 1 is rotatably inserted among the soil by sand pit, then by cylinder by interior extraction by fixed cone 3 and connecting column 5
Projection baffle 4 inside cylinder laser pen 2, is then placed in the another of sand pit by the open card of fixed fastener 1 by laser pen 2
Side, enables the horizontal component and ground face contact of projection baffle 4, and the vertical portion of projection baffle 4 stretches to sky, enables cylinder laser pen 2
The laser of projection can throw the vertical portion in projection baffle 4, then the laser rays that cylinder laser pen 2 projects can cross sand pit position
Above sand pit, play the role of comparing line of reference, to complete a series of activities.
