Abstract
The utility model discloses a miter saw head cover which comprises a fixed protection cover, a connecting rod and a movable protection cover respectively mounted on a bracket; one end of the connecting rod is mounted on the bracket and the other end of the connecting rod is connected with the movable protection cover; a gap is machined on the fixed protection cover corresponding to a saw blade locking nut, and a baffle for covering on the gap is mounted on the fixed protection cover. The miter saw head cover has simple structure, low cost and convenient machining, and makes the assembly and disassembly of the saw blade become more convenient and rapider, reduces the workload of workers and improves the work efficiency.
Description
Technical field
The utility model relates to a kind of electric cutting tool of mechanical field, is specifically related to a kind of diagonal cutting saw head-shield of quick detachable saw blade.
Background technology
Diagonal cutting saw is widely used in mechanical field, can be used to materials such as cutting metal, timber, plastic plate and fiberboard.The diagonal cutting saw head-shield generally comprises fixed blade guard and flexible blade guard, and two protective covers just in time encase the effect of saw blade to play the protection saw blade and to improve processing safety when closing up.When pushing saw downwards by operating grip, the upset that can make progress along with the decline of saw blade of the flexible blade guard of diagonal cutting saw, the exposed portions serve saw blade, and then material carried out cutting processing.But this structure makes the saw blade dismounting become pretty troublesome, must disassemble flexible blade guard earlier, and this is extremely inconvenient.
The utility model content
Goal of the invention:, the utility model proposes a kind of diagonal cutting saw head-shield of quick detachable saw blade in order to overcome the deficiencies in the prior art.
Technical scheme: for solving the problems of the technologies described above, diagonal cutting saw head-shield of the present utility model comprises fixed blade guard, connecting rod and the flexible blade guard that is installed on the bracing frame, and an end of connecting rod is installed on the bracing frame, and the other end of connecting rod is connected with flexible blade guard; Position corresponding with the saw blade locking nut on the fixed blade guard has breach, and the baffle plate that just in time blocks this breach is installed on the fixed blade guard.。
Diagonal cutting saw is installed in baffle plate on the fixed blade guard by screw in the process of using, and just in time the breach on the fixed blade guard is blocked, and just in time encases saw blade when the fixed blade guard of diagonal cutting saw and flexible blade guard close up to play the effect of protection saw blade; When pushing saw downwards by operating grip, the upset that can make progress along with the decline of saw blade of the flexible blade guard of diagonal cutting saw, the exposed portions serve saw blade, and then material carried out cutting processing.When needs dismountings or when changing saw blade, flexible blade guard is upwards dug, again the on the fixed blade guard taken off with the screw screw, second screw is unclamped, and serve as axially to go up the baffle plate that overturns with second screw, can expose the locking nut of saw blade.At this moment, can directly unclamp locking nut, take off saw blade, and needn't more whole flexible blade guard be disassembled with spanner.
Beneficial effect: diagonal cutting saw head-shield of the present utility model, simple in structure, with low cost, easy to process, can make the saw blade dismounting become more convenient, reduce workman's amount of labour, increase work efficiency.
Description of drawings
Structural representation when accompanying drawing 1 is opened for flexible blade guard and baffle plate.
Structural representation when accompanying drawing 2 is the flexible blade guard closure.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
Shown in attached Fig. 1 and 2, diagonal cutting saw head-shield of the present utility model comprises fixed blade guard 1, connecting rod 2 and the flexible blade guard 3 that is installed on the bracing frame 4, and an end of connecting rod 2 is installed on the bracing frame 4, and the other end of connecting rod 2 is connected with flexible blade guard 3; Position corresponding with the saw blade locking nut on the fixed blade guard has breach, and the baffle plate 5 that just in time blocks this breach is installed on the fixed blade guard.
Diagonal cutting saw is installed in baffle plate 5 on the fixed blade guard 1 by screw 6 in the process of using, and just in time the breach on the fixed blade guard 1 is blocked, and the fixed blade guard 1 of diagonal cutting saw and flexible blade guard 3 just in time encase saw blade to play the effect of protection saw blade when closing up; When pushing saw downwards by operating grip, the flexible blade guard 3 of diagonal cutting saw can the upwards upset along with the decline of saw blade, the exposed portions serve saw blade, and then material carried out cutting processing.When needs dismountings or when changing saw blade, flexible blade guard 3 is upwards dug, again first screw 6 on the fixed blade guard 1 is taken off, second screw 7 is unclamped, and serve as axially to go up the baffle plate 5 that overturns with second screw 7, can expose the locking nut 8 of saw blade.At this moment, can directly unclamp locking nut, take off saw blade, and needn't more whole flexible blade guard be disassembled with spanner.Diagonal cutting saw head-mounting device of the present utility model, simple in structure, with low cost, easy to process, can make the saw blade dismounting become more convenient, reduce workman's amount of labour, increase work efficiency.
The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
