Abstract
The utility model discloses a chain saw, which comprises a shell body, wherein a motor is arranged in the shell body, the chain saw is connected with the motor through a speed-down device, and a handle is arranged on the shell body. The utility model also comprises a support frame arranged on the shell body, the support frame comprises a connecting part in fitting connection with the shell body, and a support part connected with the connecting part, wherein the support part is positioned in front of the shell body when the chain saw is in the working state. The chain saw of the utility model is additionally provided with the structure of the support frame, so that when operators operate the utility model, the utility model can have favorable support effect and operators can save labor for working.
Description
Technical field
The utility model relates to a kind of chain saw.
Background technology
Existing chain saw is when work, and the active force that its operate portions saw chain produces when cutting can directly act on the operator on hand, so can make operating machines that the operator will relatively exert oneself can make its fatigue very soon.In addition, chain saw is in when work, if the working range of its saw chain is during greater than the cut coverage of processing object, the operator need carefully control saw chain and surpass the cutting of scope to prevent saw chain.
The utility model content
Can not provide good support when the work and can not control defective such as saw chain working range for overcoming existing chain saw, a kind of chain saw of excellent support that self can provide is provided the utility model, and its saw chain working range is adjustable simultaneously.
The purpose of this utility model is achieved in that a kind of chain saw, and it includes housing, be installed on power set in the described housing and deceleration device, peace is changeed the handle on described housing and join the saw chain of knot with described deceleration device; It also includes the bracing frame that is installed on the described housing, and support frame as described above includes connecting portion and cradle portion, and wherein said connecting portion activity is joined and tied on described housing.
Compared with prior art, the beneficial effects of the utility model are: set up support frame structure on chain saw, make the operator when the operation chain saw carries out work, can obtain good support; And because bracing frame is that activity is coupled on the housing, make that also the relative housing in position of bracing frame is adjustable, therefore can control the working range of the saw chain of chain saw with respect to the position of housing by the support portion of adjusting bracing frame.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the cutaway view of the utility model chain saw first embodiment, and wherein bracing frame is not in locking state.
Fig. 2 is the cutaway view of the utility model chain saw first embodiment, and wherein bracing frame is in locking state.
Fig. 3 is the cutaway view of the utility model chain saw second embodiment.Wherein:
10 housings, 20 bracing frames, 22 connecting portions, 222 grooves, 24 support portions, 30 locking devices, 32 pin portions, 34 handle portions
The specific embodiment
Creating conception of the present utility model is to set up a supporting construction for traditional chain saw, and this structure just is installed on the housing of chain saw and forms structures with other of chain saw and take place not related, so in the utility model specific embodiment, other structures to chain saw not are described.
See also shown in Fig. 1,2, the support portion 24 that bracing frame 20 includes connecting portion 22 and joins with connecting portion 22, connecting portion 22 is coupled to the bottom of housing 10.The 24 one-tenth U-shapeds in support portion, its middle groove is used for saw chain 12 to be passed through.In order to make the position of 24 relative chain saw housings, 10 front portions, support portion adjustable, connecting portion 22 slidably can be coupled to the bottom of housing 10, its mode can be the known structure of persons skilled in the art, for example, guide rail structure or the like.For connecting portion 22 being locked on the precalculated position of housing 10 bottoms, the utility model also includes locking device 30.Locking device 30 rotating being coupled on the housing 10, it includes pin portion 32 and handle portion 34, and wherein turning handle hand 34 can drive 32 rotations of pin portion.Some grooves 222 of connecting with pin portion 32 of being used for are set at interval on connecting portion 22.Turning handle hand 34 makes pin portion 32 and groove 222 connect or remove and connects, so that connecting portion 22 relative housings can not move or move.For locking device, it also can be the known other technologies scheme of persons skilled in the art, for example screw lock structure or the like.
See also shown in Figure 3, because bracing frame 20 is positioned at the front portion of chain saw housing 10, sometimes operator's work is made troubles, the utility model also provides a solution to make bracing frame can be rotated to the rear end of chain saw housing 10, its mode is the bottom that bracing frame 20 connecting portions 22 are pivotally connected to housing 10, can carry out 180 degree rotations, its implementation is that persons skilled in the art are known, therefore repeats no more.Like this, the operator can rotate to bracing frame 20 rear end of housing 10 when not needing bracing frame 20.
Slidably be connected on the housing 10 and be rotationally connected with on the housing 10 for above-mentioned bracing frame 20, persons skilled in the art can combine it fully.A kind of scheme below is provided: bracing frame is provided with first connecting portion, second connecting portion and support portion, wherein first connecting portion is pivotally connected to the bottom of chain saw housing, second connecting portion slidably is connected on first connecting portion, and the support portion is connected on second connecting portion.Because such scheme is implemented simple, therefore do not illustrating.
Because creation essence of the present utility model is that the bracing frame activity is coupled on the housing, and activity connects and just necessarily needs locking device, therefore the known locking device of persons skilled in the art does not repeat them here for concrete locking mechanism all applicable to the utility model.
