Abstract

本实用新型涉及一种可调刀片长度的手工裁切 刀,由滑动刀片,中空刀体,推动件和锁定件等组成。 本实用新型的推动件与锁定件组合成一整体推锁件, 推锁件的侧部联有定位凸缘。在刀体的定位卡口下 部有一条通槽。将推锁件压下后,定位凸缘脱离定位 卡口,推锁件带动刀片在通槽内滑动调节,松开指压 力后,推锁件依其弹力使定位凸缘卡入定位卡口内固 定。

Description

本实用新型涉及一种可调刀片的手工裁切刀。
现有技术中,裁切刀的刀片长度可调,其调节定位是靠推动件上的定位凸缘卡紧在刀体两内侧的卡口内而实现的。在调节刀片伸缩长度和锁定在有级位置时,需要分别操作推动件和锁定件。由于推动件上的两定位凸缘在调节刀片伸缩长度的过程中始终与中空刀体两内侧的多个卡口受力磨擦滑动,因此不仅在调节刀片伸缩长度时操作不便、手感不适,而且缩短了推动件和锁定件的使用寿命。
本实用新型的目的在于克服上述现有技术中的不足而提供一种在调节刀片时集推动、锁定功能于一体的级进式手工裁切刀,以方便操作,延长产品使用寿命。
本实用新型的目的通过以下技术措施来达到:包含有若干个定位卡口的中空刀体,滑动刀片,推动件及锁定件。本实用新型的推动件与锁定件组合为一整体推锁件。在推锁件的侧部联有定位凸缘。所述中空刀体的定位卡口下部有一通槽。操作时,只要用手指将推锁件轻轻下按,使其侧部的凸缘脱离刀体定位卡口即可带动刀片在刀体内滑动伸缩,松开指压力时,推锁件依其自身回弹力使其侧部凸缘进入刀体相应的定位卡口内,即可实现有级定位锁止。
本实用新型刀片在刀体内滑动时,推锁件凸缘与刀体内两侧 多个定位卡口间无相对滑动磨擦,同时,凸缘与定位卡口均采用梯形截面形状,啮合锁定后能自动消除配合间隙,因此提高了级进机构的使用寿命和滑动刀片的定位锁止精度。
本实用新型将结合下列附图对实施例作详细描述。
图1为本实用新型外形图。
图2为本实用新型沿图1A-A向剖视图。
参看图1、图2,推锁件1上的柱形端头6与滑动刀片3固定联结,推锁件1可带动滑动刀片3在刀体2内伸缩滑动和有级锁止。操作时,只要用手指将外露于刀体面的推锁件1的纽头轻轻下按,使推锁件1上两侧的梯形截面凸缘5脱离刀体2内的梯形截面定位卡口4,这时,推锁件的凸缘5在定位卡口4下部的通槽7内滑动,并带动滑动刀片3在刀体2内伸缩滑动。放松手指压力后,利用推锁件1自身向上的回弹力,使其两侧凸缘5进入刀体相应位置的定位卡口4内,即可实现有级定位锁止。
