Further, the connecting pin one end is equipped with a plurality of connection teeth, and each connection teeth are 44 ° of saws
Tooth form.
Further, the distance of two adjacent connection teeth is 2.5mm.
Further, the other end of the connecting pin is equipped with helicitic texture.
Further, the retaining spring steel plate uniform intervals are fixed on the inside of the positioning shell.
Further, a fixing groove is formed on the inside of each retaining spring steel plate both ends and the positioning shell, used
In stationary spring.
Further, the both ends of the connecting pin are cylindric.
The present invention has the advantages that a kind of expansion biting connecions mechanical connecting joint of the present invention, 1, compared in the market function,
Weight, size have very big diminution, reduce rolled steel dosage, save manufacturing cost；2, working security and as received basis are improved
Amount improves connector occlusion site area and unit tension, single connector is anti-by the way that square hole connecting pin is changed to cylindrical body connecting pin
Pulling force is greater than 170KN；Meanwhile it accelerating construction progress and installation quality；3, it positions in shell and adds three pieces spring leaf, having a size of length
30mm* wide 15mm* thickness 1.2mm can expand tapered end to center card slot and carry out centralized positioning, improve speed of application and connection matter
Amount；4, using matched ancillary equipment, construction speed and construction quality are improved, reduces labor intensity.

Specific embodiment
Shown in please referring to Fig.1 to Fig.3, the present invention expands biting connecions mechanical connecting joint, including a connecting pin 1, a tapered end
2, a positioning shell 3, plural pieces spring leaf 4 and a plurality of retaining spring steel plates 5, the quantity of the spring leaf 4 with it is described fixed
Position 5 quantity of steel spring plate is equal；3 inside of positioning shell, the spring leaf 4 are fixed in the interval of retaining spring steel plate 5
Between the retaining spring steel plate 5, the tapered end 2 is fixed among the spring leaf 4, carries out 360 degree using spring leaf
It positions, in work progress, it is ensured that tapered end is constructed convenient for scene to positive at the intermediate position of positioning shell 3；The connecting pin 1
One end is connected to the tapered end 2, and the other end of the connecting pin 1 is equipped with helicitic texture, and the retaining spring steel plate 5 is uniformly
3 inside of positioning shell, each 5 both ends of retaining spring steel plate and the 3 inside shape of positioning shell are fixed in interval
