Abstract
The utility model provides a double-thread screw detaching device, which comprises a fixing bracket, wherein the fixing bracket is provided with clamping grooves; clamping sleeves are arranged on the clamping grooves, and are provided with bolts; the bolts are deep in the clamping sleeves; the front ends of the bolts are movably provided with fixing sleeves; and the inner sides of the fixing sleeves are provided with threads matched with threads of screws. During use, the screws are put in the clamping sleeves on the bracket, the bolts are rotated to make the clamping sleeves clamp the threads on the screws, the screws are fixed, and the screws can be easily detached by a wrench. Compared with the conventional detaching method, the double-thread screw detaching device has the advantages that: by the new tool, the friction between the screws and a pipe wrench is reduced, manpower is reduced, the screws are easily detached in a time and labor saving mode, and the work efficiency is improved; moreover, the threads of the screws cannot be damaged.
Description
Technical field
The present invention relates to the screw rod extracting tool of use in a kind of chemical plastic production, specifically is a kind of two-flight screw provision for disengagement.
Background technology
General dismounting two-flight screw is after screw rod is taken out from machine barrel, to be placed on the wooden unit, blocks screw rod with instruments such as pipe wrench then, makes its fixing anti-sliding stop, with spanner thread head is laid down again.
The shortcoming of the method is: cause damage to break to screw flight cover element easily; And dismounting is wasted time and energy.The problem that solves: the damage for fear of instrument double threads such as pipe wrench cause, because need very energetically, can produce the frictionally damage element between jaw and the screw rod, can cause distortion, even break.
Summary of the invention
The utility model purpose provide a kind of steadily, reliable, laborsaving and to the undamaged provision for disengagement of two-flight screw.
The technical scheme of the utility model does for this reason, and a kind of two-flight screw provision for disengagement comprises fixed support; Fixed support is provided with draw-in groove; Draw-in groove is provided with cutting ferrule, it is characterized in that: cutting ferrule is provided with bolt, and bolt gos deep in the cutting ferrule; And being movably equipped with fixed cover at the front end of bolt, the inner face of fixed cover is provided with the screw thread that cooperates with screw flight.
Beneficial effect:
The utility model is placed on screw rod on the support in the cutting ferrule in use, and rotating bolt makes fixed cover block the screw thread on the screw rod, is fixed, and just can use spanner easily to carry out screw rod then and dismantle.Compare with original method for dismounting, the unloading process of new tool has reduced the friction between screw rod and the pipe wrench, has reduced manpower, and it is light to remove nature, has improved operating efficiency, saves time, and saves trouble, and dismounting easily; And can not cause screw flight to damage.
