Description
Technical field
The present invention relates to a kind of chain saw, especially a kind of chain saw with chain tension adjusters.
Background technology
PCT patent application WO9833631 discloses a kind of chain saw with chain stretching device on August 6th, 1998, and wherein, the chain saw carrier bar is fixed between two clamping disks, and is fixed on the housing with them, and housing vertically moves relatively.Hitching post passes hole in the eccentric wheel and the elongated hole on the housing, twist to be fixed on housing and guided, and among the clamping disk that can vertically move, its bolt head is fixed in eccentric wheel on the housing.For the tensioning saw chain, at first need bolt is unclamped, rotate eccentric wheel, thereby bolt and clamping disk are moved to carrier bar top direction, when saw chain reaches desired tensile force, the eccentric wheel that stops operating, and then tight a bolt, thus by stressed effect eccentric wheel and clamping disk and carrier bar are fixed on the position that sets on the housing.This saw chain tensioning method is relatively complicated, and carrier bar locking absent-mindedness easily, thereby causes the tensile force of saw chain lax, has increased the danger that saw chain is jumped off from carrier bar, to this, can only be to solve by saw chain is carried out follow-up tensioning regularly.
For solving above-mentioned chain saw tensioning problem, to be CN1174841C on November 10th, 2004 authorize the Chinese patent notification number has announced a kind of chain saw, this chain saw has a chain tension adjusters, wherein, this chain saw has a housing, and a sprocket wheel and a carrier bar of aiming at this sprocket wheel that is installed on this housing is arranged, this carrier bar stretches away from housing and the saw chain with sprocket engagement is led circularly, this carrier bar can be mounted with respect to housing and sprocket wheel in the vertical movably by a tensioning apparatus with regulating, and tensioning apparatus has an eccentric wheel that can be fixed in the backstop on the carrier bar and can rotate by means of rotating element, this rotating element is by in two shellies, outer hand wheel is formed, in, outer hand wheel can be plug-in mutually, and relatively rotate around a common axis, wherein, interior handwheel can move vertically and can be supported on the carrier bar with respect to housing, outer hand wheel is connected to carry rotating manner with eccentric wheel, and between interior handwheel and the outer hand wheel, and all pass through an offside clamping connector between outer hand wheel and the housing and be connected, after the saw chain tensioning, handwheel can static relatively being connected with outer hand wheel in this offside clamping connector can make.By said structure, this chain saw is after the saw chain tensioning, and carrier bar is difficult for absent-mindedness, guaranteed the effective tensile force of saw chain, but in the process of tensioning, needed internal handwheel and outer hand wheel to operate respectively, complicated operation, man-machine function a little less than.
For solving man-machine function problem, the Chinese patent notification number is that CN1138620C discloses a kind of chain saw, this chain saw comprises that a sprocket wheel that is rotatably supported in the housing and saw chain that be used for being guided on carrier bar, one are used to make that carrier bar vertically moves and have a chain tension adjusters that makes eccentric wheel that carrier bar moves and make the rotating device that eccentric wheel rotates, wherein, rotary connecting device between rotating device and the eccentric wheel constitutes as the clamping clutch, regulates its transposition clamping power corresponding to required chain tension.This structure makes in saw chain tensioning process, only needs a rotating device operation saw chain of tensioning simultaneously and compress carrier bar, and easy to operate, man-machine function is strong, but set clamping clutch weares and teares easily, and stable inadequately.
Summary of the invention
At the deficiencies in the prior art, the technical problem to be solved in the present invention provides a kind of chain saw, and this chain saw has strong, the stable and nonabradable chain tension adjusters of a man-machine function.
