Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-4, rotary fixture, including base 1, install support column 2 on the base 1, clamping seat 3 is installed through the bearing in the outside of support column 2, install spacing ring 4 on the clamping seat 3, spacing ring 4's inside articulates there is gag lever post 5, holding ring 6 is installed to base 1's upper end, holding ring 6 is last to have seted up constant head tank 7, the quantity of constant head tank 7 is a plurality of, a plurality of constant head tanks 7 evenly distributed on holding ring 6, a plurality of constant head tanks 7 can be so that clamping seat 3's location angle increases.

In this embodiment, install connecting plate 8 on the spacing ring 4, be provided with elastic band 9 on the connecting plate 8, the one end and the connecting plate 8 of elastic band 9 are connected, and the other end and the gag lever post 5 of elastic band 9 are connected, and elastic band 9 can drive gag lever post 5 automatic re-setting through elasticity, gag lever post 5 and constant head tank 7 sliding connection, spacing ring 4 and base 1 contact, and gag lever post 5 can carry on spacingly to clamping seat 3.

In this embodiment, sliding connection has two drive plates 10 that are symmetrically distributed on holder 3, clamping piece 12 is installed to drive plate 10's upper end, clamping piece 12 and holder 3 contact, be provided with extension spring 11 on the drive plate 10, the one end of extension spring 11 is connected with drive plate 10, the other end and the holder 3 installation of extension spring 11, extension spring 11 can drive clamping piece 12 through elasticity and carry out the clamping to the mould, the internally mounted of holder 3 has guide bar 13, guide bar 13 and drive plate 10 sliding connection, guide bar 13 can carry on spacingly to drive plate 10.
