Abstract

本实用新型涉及一种紧固夹。是由位于支架1上的螺母2和与之配合的螺杆3组成,其特征是:螺母2和螺杆3上的螺纹为多头螺纹。使用时,螺杆的进给、退出速度是单头螺纹螺杆的进给、退出速度的若干倍,从而节省了紧固、固定工件时的时间,提高了工作效率。

Description

一种紧固夹
本实用新型涉及一种紧固夹。
目前,市场上出售的紧固夹,是由位于支架上的螺母和与之配合的螺杆组成,其螺母和螺杆上的螺纹为单头螺纹,其缺点是用来紧固、固定工件时螺杆的进给速度和退出速度慢,工效低。
本实用新型的目的是提供一种由多头螺纹配合的螺母和螺杆组成的紧固夹,以成倍螺距的进退解决背景技术中单螺距进退速度慢的不足。
本实用新型是采用如下技术方案来实现的:一种紧固夹,由位于支架上的螺母和与之配合的螺杆组成,其特征是:螺母和螺杆上的螺纹为多头螺纹。
由于采用了上述技术方案,螺母和螺杆上的螺纹为多头,其螺杆的进给、退出速度是单头螺纹螺杆的进给、退出速度的若干倍。从而节省了紧固、固定工件时的时间,提高了工作效率。
下面结合本实用新型的实施例来进一步说明技术方案。
图1--是本实用新型的结构示意图;
图2-是螺纹为2头的螺杆端部视图。
参考图1、图2。支架1下端设有螺母2,螺杆3与螺母2配合安装在支架1上,螺杆3的上端设有压垫4,下端套装有一摇杆5。螺母2和螺杆3上的螺纹为2头螺纹。使用时顺时针转动摇杆5,带动螺杆3转动,即可将压垫4和支架1之间的工件紧固、固定了;逆时针转动摇杆5,螺杆3即可退出。
