Utility model content
In order to solve the defect that above-mentioned technology exists, the utility model provides a kind of release handle that facilitates the wall surface grinding machine angle regulator with head angle.
The utility model realizes the technical scheme that above-mentioned technique effect adopts:
A kind of angle regulator of wall surface grinding machine, comprise handle and head, pinned connection on the front fork of described handle and described head, wherein, described bearing pin is at least provided with the torsion spring that an elastic metallic bar is formed, described torsion spring comprises integrated torsion spring arm, be located at the distortion winder of described torsion spring arm stiff end and be located at the ear handle of described torsion spring arm free end, the upper surface of described ear handle has recessed concave surface, this concave surface is provided with anti-skidding concave point, described torsion spring arm free ending tool has aduncate arc lattice stopper, described torsion spring arm free end slopes inwardly to arrange and described arc lattice stopper can be conflicted with the stop part inside described front fork coordinate.
The angle regulator of above-mentioned a kind of wall surface grinding machine, is provided with longitudinal transition part between described torsion spring arm stiff end and described distortion winder, and the outer end of described arc lattice stopper is provided with cross transition portion, and described cross transition portion is fixedly connected with described ear handle.
The angle regulator of above-mentioned a kind of wall surface grinding machine, the end of described distortion winder is provided with hook part, and described hook part is fixedly connected with described bearing pin.
The beneficial effects of the utility model are: torsion spring arm free end of the present utility model slopes inwardly and is arranged so that arc lattice stopper just can be conflicted with the stop part inside front fork and coordinates, when needs handle and head are vertical angle, first outwards being rotated by handle makes itself and head open in obtuse angle, then pull ear handle torsion spring to be turned clockwise certain angle, arc lattice stopper is made to drop on the inner side of front fork, then handle is unclamped, arc lattice stopper is conflicted with the stop part inside front fork coordinate, under the moment loading of distortion winder, handle withstands by the arc lattice stopper of torsion spring arm free end firmly, handle can not be turned round around bearing pin, now handle and head can present stable vertical angle, be convenient to wall top of polishing.When polishing vertical metope, pull ear handle and handler departs from making the stop part place of arc lattice stopper in the past inside fork, that can recover between handle and head is arbitrarily angled.Can make in a free state to keep specific angle between handle and head, in use also can according to use attitude free adjustment, and not malfunctioning activity.

Detailed description of the invention
For making to do further to understand to the utility model, referring to Figure of description and specific embodiment, the utility model is described in further detail:
As shown in Figures 1 to 5, a kind of angle regulator of wall surface grinding machine, comprises handle 2 and head 1, and the front fork 21 of handle 2 is connected with the bearing pin 4 on head 1.Wherein, improve as one of the present utility model, bearing pin 4 is at least provided with the torsion spring 3 that an elastic metallic bar is formed, this torsion spring 3 comprises integrated torsion spring arm 32, is located at the distortion winder 34 of torsion spring arm 32 stiff end and is located at the ear handle 31 of torsion spring arm 32 free end.The upper surface of ear handle 31 has recessed concave surface, and this concave surface is provided with anti-skidding concave point 311, and recessed concave surface coordinates anti-skidding concave point 311 can prevent from holding skidding when getting.Torsion spring arm 32 free ending tool has aduncate arc lattice stopper 36, and torsion spring arm 32 free end slopes inwardly and is arranged so that arc lattice stopper 36 can be conflicted with the stop part 211 inside front fork 21 and coordinates.
Concrete, in the angle regulator of above-mentioned a kind of wall surface grinding machine, longitudinal transition part 33 is provided with between torsion spring arm 32 stiff end and distortion winder 34, the outer end of arc lattice stopper 36 is provided with cross transition portion 37, cross transition portion 37 is fixedly connected with ear handle 31, whole torsion spring 3 is one-body molded by elastic metallic bar, and ear handle 31 is oval working of plastics, also can be other materials and makes.The end of distortion winder 34 is provided with hook part 35, and this hook part 35 is fixedly connected with bearing pin 4.
Torsion spring arm 32 free end of the present utility model slopes inwardly and is arranged so that arc lattice stopper 36 just can be conflicted with the stop part 211 inside front fork 21 and coordinates.When needs handle 2 is vertical angle with head 1, first outwards being rotated by handle 2 makes itself and head 1 open in obtuse angle, then pull ear handle 31 torsion spring 3 to be turned clockwise certain angle, arc lattice stopper 36 is made to drop on the inner side of front fork 21, then unclamp handle 2, arc lattice stopper 36 is conflicted with the stop part 211 inside front fork 21 and coordinates.Under the moment loading of distortion winder 34, handle 2 withstands by the arc lattice stopper 36 of torsion spring arm 32 free end firmly, and handle 2 can not be turned round around bearing pin 4, and now handle 2 and head 1 can present stable vertical angle, is convenient to wall top of polishing.When polishing vertical metope, pulling ear handle 31 handler and 2, stop part 211 place of arc lattice stopper 36 in the past inside fork 21 being departed from, that can recover between handle 2 and head 1 is arbitrarily angled.Angle regulator of the present utility model is simple and practical, can flexibly and easily release handle the angle between 2 and head 1, especially when polishing wall top, can be vertical angle regularly between handle 2 and head 1, significantly reduce the operation easier of polishing work, improve efficiency and the polishing quality of metope polishing.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and description; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications; these changes and improvements all fall in claimed scope of the present utility model, and the protection domain that the utility model requires is defined by appending claims and equivalent thereof.
