Include：Screw rod, pedestal and the injection pump housing push away seat, and the screw rod is fixedly mounted on pedestal by bearing, it is characterised in that：
The pedestal is equipped with guider, which is located at the lower section of screw rod, and the injection pump housing pushes away seat and is slidably socketed leads at this
To on device；The injection pump housing, which pushes away, is hingedly provided with nut block on seat, handing-over rotary position and the screw rod phase of the nut block
It is corresponding, injection pump housing pushing block is additionally provided with the top of nut block.
Preferably, the screw rod is trapezoidal screw, which is made of copper, its pitch is 2~3mm.
Preferably, the nut block is nylon material, and the screw hole in the nut block opens side and removes the latter half, upper half
Partial screw hole is interlocked with screw rod.
Preferably, rotating arm is equipped with described nut block one end, the other end of nut block is inlaid with iron plate and pressure
Tight arm.
Preferably, pushed away in the injection pump housing and magnet is equipped with seat, the iron plate on the position and nut block of the magnet
Position is corresponding.
Preferably, the guider is made of guide shaft and guide copper sleeve, and paired guide shaft is parallel to each other fixation
On pedestal, guide copper sleeve pushes away seat with the injection pump housing and is connected, and slides fitting with guide shaft.
Beneficial effect：
The utility model and passes through guider and hinge by using the clasp nut structure of big pitch trapezoidal gear
The form of folding is connect, realizes the quick and precisely clutch of nut and screw rod, while improves mobile stream overall after nut is opened
Smooth degree, makes the mobile reset of pushing block bottom plate more easy to be smooth；The fixed form of magnet attracted type is that clasp nut realizes quick
Efficiently connection, solves the technological deficiency connected in the prior art.The utility model is simple in structure, and mounting and adjusting is easy, nut
Clutch is smooth accurate, and is attracted accuracy height, and connection fixation is solid.
