Description
Technical field
The invention belongs to the chain saw technical field, be specifically related to the instrument of exempting from dismounting guide plate and quick tension chain device on a kind of chain saw.
Background technology
Chain saw is the electric tool that a kind of people commonly use, and multiplex in cutting timber, chain saw in use for some time, because cutting timber is to the reaction force of chain saw chain, chain saw braking vane system is produced powerful impulsive force, so that carrier bar, sprocket wheel are worn, relaxation appears in the chain elongation.When chain when pine too, in cutting process, may make chain releasing, cause cutting smoothly, service time of decrease in efficiency, shortening chain saw.
Nowadays a lot of chain saws are when demolition and maintenance chain guide and tension chain, need to use specific purpose tool to unscrew hexagonal flange nut on the side plate, can not dismantle without instrument, its complicated operation, waste time and energy, efficient is low, increased amount of parts, the user has been had certain operation requirements.Therefore research and develop a kind of exempt from instrument dismounting guide plate and quick tension chain device necessary, although now the chain regulator of much exempting from instrument is arranged also, their component processing costs are high, or complicated structure.Be patent " instrument of the exempting from adjustment structure of the high chain saw chain tensity of a kind of electric machining cost " technical scheme of CN 202746523 U such as notification number, its adjustment ring inside is provided with adjusting gear and is connected with pinion, the coaxial connection of an end of pinion and worm screw, the other end of worm screw and described adjustment screw afterbody are in transmission connection by worm gear.And the processing cost of worm gear is high.And for example publication number is the patent of the CN 1827275A technical scheme that " has the chain saw of exempting from tool-type chain tensioning device and guide rod lock ", its adjusting device comprises that one functionally is connected to the element on the guide rod, a series of intermeshing driver part and the hand operable member that can impel guide rod to move, a guide rod fastener.
So its complex structure, complex structure not only cost are high, and parts are many, and the probability of parts damages is just large, and the reliability of adjusting device is low.In addition, above-mentioned technical scheme all can not solve chain saw and in use all must rely on specific purpose tool dismounting chain saw braking vane could safeguard the problem of replacing chain guide.
Summary of the invention
High for chain stretching device complex structure of the prior art, cost, can not solve chain saw and in use all must rely on specific purpose tool dismounting chain saw braking vane could safeguard the problem of changing chain guide, invent the instrument of exempting from dismounting guide plate and quick tension chain device on a kind of chain saw.
Above-mentioned goal of the invention is achieved through the following technical solutions, the instrument of exempting from dismounting guide plate and quick tension chain device on a kind of chain saw, comprise the chain saw braking vane, its main points are to be equipped with on the chain saw braking vane exempts from instrument dismounting guide plate and quick tension chain device, and described instrument dismounting guide plate and the quick tension chain device of exempting from comprises and exempt from instrument dismounting guide agency, the quick tension chain of the instrument of exempting from mechanism; The described instrument dismounting guide agency of exempting from comprises the locking nut of locking guide plate, is contained in the guide plate stud on the casing; The locking nut head of described locking guide plate is equipped with the first handle that can pull open into spiral arm; Describedly exempt from that the quick tension chain of instrument mechanism comprises driving gear, driven gear, is contained in adjusting bolt on the driven gear, the adjusting nut with the adjusting bolt engagement, the adjustable column on the adjusting nut, adjustable column is used for inserting the locating hole of guide plate; The driving gear head is equipped with the second handle that can pull open into spiral arm, and driving tooth is contained on the chain saw braking vane by the erection column on the chain saw braking vane.
As preferably, the described first handle that can pull open into spiral arm is provided with return spring, and described return spring is fixed on the first handle by the straight pin on the locking nut head; First handle is provided with locating dowel, and the position that the chain saw braking vane is corresponding is provided with a delineation position shrinkage pool; After first handle resetted, the location shrinkage pool by on the locating dowel insertion chain saw braking vane played anti-loosening effect to locking nut.
As preferably, the second handle that can pull open into spiral arm that described driving gear head is equipped with is provided with return spring, and return spring is fixed on the second handle by the straight pin on the driving gear head; Pull open into the second handle of spiral arm and carry out turn, driving gear transfer driven gear then, the driven gear transmission is contained in the adjusting bolt on the driven gear, adjusting bolt transmission adjusting nut, thereby make the left and right movement of adjustable column on the adjusting nut, and adjustable column drives the left and right movement of guide plate of inserting its locating hole, thereby reaches the purpose of quick tension chain.
As preferably, be provided with dust cap above the described driven gear, dust cap rises driven gear and prevents displacement and dustproof effect; Adjusting bolt is provided with the spacer that inserts the chain saw braking vane, and spacer plays fixation to adjusting bolt.
The present invention compared with prior art has following advantage: simple in structure, use safe, easy and simple to handle; Can not rely on specific purpose tool dismounting chain saw braking vane to safeguard and change chain guide, can not rely on again specific purpose tool that chain saw chain is carried out the tensioning adjustment, so it can increase substantially the operating efficiency that people use chain saw.
