Background technology
Brush saw is a kind of mowing mechanism high speed rotating by the driving of afterbody petrol engine, the drive of the power transmission shaft in tube connector head, thereby makes the graden machine of beating the grass rope or the cutting of blade formation high speed rotating in the mowing mechanism.This equipment is in when work, and the petrol engine of afterbody is born on one's body the operator, and the operator grips handle on the tube connector with the Cutting Control direction, thereby reaches the pruning purpose.In this cutting process, must guarantee tube connector and the fan housing that is installed on the petrol engine forms fixed relationship, therefore often between tube connector and fan housing, also have additional the fixed cover of rubber system, through fixed cover to reach the purpose that tube connector is fixedlyed connected with fan housing.Yet said structure is after using for a long time, and fixed cover often loses fixation, makes the relative fan housing of tube connector loosening, and when the work of operation brush saw rotation direction, tube connector can drive fixed cover and rotate together, greatly influences operational stability.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and a kind of pipe connecting structure that connects fastening, that operational stability is good a kind of brush saw is provided, and this syndeton also has the high shockproof and mechanical advantage that brings the body shake injury of minimizing itself.
Technical problem of the present utility model is achieved through the following technical solutions:
A kind of pipe connecting structure of brush saw, it comprises interconnected tube connector and fan housing, is provided with fixed cover between tube connector and the fan housing, and the fan housing front end is provided with the fan housing lid that fixed cover is fixed, the fan housing rear end is provided with clutch assembly, and this clutch assembly is bearing on the interior bearing of fan housing; Also be provided with the power transmission shaft that is connected with clutch assembly in the described tube connector, be embedded with stator on the described fixed cover inwall, this stator is provided with salient point, the corresponding connecting hole that is equipped with this salient point that is provided with on tube connector; Described fixed cover outer wall is provided with a plurality of locating slots, the corresponding positioning strip that is equipped with locating slot that is provided with on the fan housing inwall; Or on the fixed cover outer wall, be provided with a plurality of positioning strips, correspondingly on the fan housing inwall, be provided with the locating slot equipped with positioning strip.
Described fixed cover is hollow cone platform shape, and this hollow cone platform has a cutting groove that does not run through along the diameter radial cuts, makes fixed cover form the semi-circular of two mutual obvolvents, one side and two semiorbicularly link to each other the another side one that links to each other; Described stator is two, and is embedded respectively on two semiorbicular inwalls.
Outer set locating slot or the positioning strip of described fixed cover is 4～6, correspondingly also is 4～6 at fan housing inwall set positioning strip or locating slot.
Described fixed cover is a flexible rubber lagging.
Compared with prior art, the utility model mainly is that the fixed cover that will be installed between tube connector and the fan housing improves, and is embedded with the stator of being with salient point at the fixed cover inwall, the corresponding connecting hole that is equipped with salient point that is provided with on tube connector; Be provided with locating slot or positioning strip at the fixed cover outer wall, correspondingly be provided with equipped positioning strip or locating slot at the fan housing inwall, by in the fixed cover, the architecture advances of outer wall makes and forms annexation the most closely between tube connector and the fan housing, thereby the brush saw of avoiding traditional structure in the course of the work, the defective that tube connector is loosening easily relative to fan housing and the drive fixed cover rotates together, so really realized the purpose that tube connector and fan housing formed a fixed connection through fixed cover, operational stability is better, simultaneously, this structure also has the high shockproof and mechanical advantage that brings the body shake injury of minimizing itself.

Embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 1～shown in Figure 3,1. tube connector, 11. connecting holes, 2. power transmission shaft, 3. fan housing lid, 4. screw, 5. fixed cover, 51. locating slots, 52. cutting grooves, 6. fan housing, 61. positioning strips, 7. stator, 71. salient points, 8. bearing, 9. clutch assembly, 10. collar.
A kind of pipe connecting structure of brush saw comprises metal tube connector 1 and fan housing 6.Described tube connector front end connects the mowing assembly (not shown) of brush saw, and the rear end directly is plugged on the fan housing 6, also is provided with four connecting holes 11 on the tube connector rear end.Be equipped with on the tube connector 1 for the operator and hold the handle (not shown) of holding, be provided with in the tube connector 1 gasoline engine power is passed to power transmission shaft 2 on the mowing assembly.
Be provided with fixed cover 5 between described tube connector 1 rear end and the fan housing 6, this fixed cover adopts flexible rubber lagging to make, it is as Fig. 1, the hollow cone platform shape that is shown in Figure 3, along fixed cover 5 end face diameter radial cuts a cutting groove that does not run through 52 is arranged, make fixed cover form the semi-circular of two mutual obvolvents through this cutting groove, and two semiorbicular one side link to each other, the another side one that links to each other.Respectively be embedded with a metal stator 7 on two semiorbicular fixed cover 5 inwalls, fixed cover and stator are equipped with two salient points 71 for directly integrated on each stator 7.The design of said structure mainly is to pack into smoothly on the tube connector 1 for the ease of fixed cover 5, the one side that needs during installation two semiorbicular fixed covers are never connected pulls open, be clamped in then on the tube connector 1, and four salient points 71 on two stators 7 are fitted in four connecting holes 11 of tube connector, like this, tube connector 1 relative fixed cover 5 just forms the relation that is fastenedly connected.The fixed cover outer wall is provided with four locating slots 51 vertically, corresponding four positioning strips 61 that are equipped with locating slot that are provided with at fan housing 6 inwalls, fixed cover 5 covers 3 by the fan housing of fan housing front end and carries out screw 4 and be fixed after equipped mutually locating slot and positioning strip location and installation are fan housing 6 in.
