Abstract

本发明公开了一种多功能手锯，属五金工具技术领域，它是由锯柄、锯弓、锁紧套、锯条、锯条胀紧器和工具装夹组成，其结构特点是在锯柄上设有锯条胀紧器，更换锯条十分方便，只需要把胀紧手柄一扳一推即可完成。锯弓的长短可以根据锯条的长短来调节，可适用于多种型号的锯条。锯柄和锯弓可以分开使用，锯柄前端设有工具装夹，工具装夹内设有卡簧，工具装夹上可根据不同的需要换装不同的备用工具，使该手锯除了锯割以外还具有划玻璃、切瓷砖、定点、划线、打孔、磨边等多种功能。

Description

一种多功能手锯
技术领域
本发明涉及一种五金工具，确切的说是一种多功能手锯。
背景技术
目前，市场上销售的手锯，锯弓的长度都是固定不变的，一般都只能配用固定长度的锯条，当遇到特殊情况必须使用其他型号的锯条时，此锯就无法适用了；还有，现有的手锯更换锯条时都要先拧松调节螺丝，挂好锯条后再次拧紧螺丝才能使用，每更换一次锯条都要拧来拧去好几次较为繁琐。
发明内容
本发明的目的就是要克服上述手锯的两个缺陷，提供一种锯弓长度可以随意调整的伸缩锯弓，使其适用于多种长度规格的锯条，并且还可以实现快速更换锯条。锯柄和锯弓可以分开使用，锯柄上设有工具装夹，工具装夹上可换装多种备用工具，使该手锯除了锯割以外还具有划玻璃、切瓷砖、定点、划线、打孔、磨边等多种功能。
本发明的方案是由锯柄、锯弓、锁紧套、锯条、锯条胀紧器和工具装夹组成，其结构特点是在所述的锯柄上设有锯条胀紧器，锯柄前端与锯弓以插件相连，插入的深度以配用的锯条长度为准，并在接头处设有锁紧套。
本发明所述的锯条胀紧器，是由胀紧手柄、偏心轮、转动轴和胀紧杆组成，其结构特点是，在所述的偏心轮上设有胀紧手柄，偏心轮前面设有胀紧杆，当向前推动胀紧手柄时，偏心轮就会绕轴转动并逐渐推动胀紧杆上部向前转动，胀紧杆下部就会拨动锯条挂杆向后移动，从而实现快速胀紧锯条。当换用另外一种型号的新锯条时，由于锯条长度不一样，可根据新锯条的长短先把锯弓长度调整适当、挂上锯条，然后边推动胀紧手柄边旋转锯条挂杆后面的调节螺栓，使其松紧适中。当再次更换同样型号的锯条时，只需要把锯条胀紧手柄一扳一推即可完成。
本发明所述的可伸缩锯弓，它是由锯柄前端的圆管插入锯弓圆管内，从而实现锯弓长度的伸缩，并在接头处设有锁紧套加以固定。
本发明所述的工具装夹，它设在锯柄前端的圆管内，使用时须拧松锯弓上的锁紧套，拔出锯柄前端的圆管，露出工具装夹，工具装夹内设有卡簧，根据不同的需要，可换装不同的工具，从而实现划玻璃、切瓷砖、定点、划线、打孔、磨边等多种功能。
下面结合附图作进一步说明。
附图说明
图1为本发明结构示意图；
图2为本发明锯柄前端所设工具装夹示意图；
图3为本发明伸缩锯弓紧固示意图；
图4为本发明锯弓前端设有夹紧开口示意图。
具体实施方式
图1中示出的锯条胀紧器，是在锯柄1的上部设有偏心转动轴11，转动轴上设有偏心轮8，偏心轮上部设有锯条胀紧手柄7，锯柄1的下部设有胀紧杆转动轴10，转动轴上设有胀紧杆9，胀紧杆下端设有拨叉，通过调节螺栓2与可移动的锯条挂杆3相连，锯条挂杆内设螺纹与调节螺栓2相连，锯条挂杆3上设有锯条4。
图1、图3、图4中示出的是可伸缩锯弓，是在锯柄1的前端设有圆管，此圆管通过开口14，插入锯弓5内，锯弓与锯柄的接头处设有锁紧套6。
图2中示出的是锯柄前端设置的工具装夹，它是在锯柄1的前端圆管内设有工具装夹12，工具装夹内设有卡簧，工具装夹上设有玻璃刀13，工具装夹上除玻璃刀外，还可以根据不同的需要，换装切瓷砖、定点、划线、打孔、磨边等其它工具。
