CN201516598U - Damping device for electric pick - Google Patents

Abstract

The utility model relates to an electric pick, in particular to a damping device for the electric pick, which comprises an electric pick body, a rotary liner, an auxiliary handle and an execution part, wherein, the electric pick body is connected with the left end of the rotary liner; the auxiliary handle is connected with the right end of the rotary liner; one end of the execution part is positioned in the rotary liner; a spring damping device is arranged on the rotary liner; the spring damping device comprises a plastic sleeve, a spring and a snap ring; the rotary liner is sheathed with the spring; the spring is sheathed with the plastic sleeve; an inner ring rib at the left end of the plastic sleeve is matched with the outer wall of the rotary liner; a ring groove is formed on the rotary liner close to the outer wall of the right end of the plastic sleeve; the snap ring is positioned in the ring groove; and the spring is positioned between the inner ring rib and the snap ring. The damping device for the electric pick has the advantages that reacting force and shake can be absorbed effectively when the electric pick operates, the undesirable impact on a user caused by the reacting force can be reduced, the time that fatigue occurs in the operation can be prolonged, and the working efficiency can be improved.

Description

The electric pick damping device

Technical field

The utility model relates to a kind of electric pick, particularly a kind of electric pick damping device.

Background technology

Existing electric pick is not provided with shock-damping structure or shock-damping structure is set but DeGrain, handle grip partly shakes greatly, and reaction force just directly affacts on operator's the arm on the electric pick, the operator operates machines and will feel tired at short notice, very easily cause to grip finger and produce numb, phenomenon such as turn white, it is serious also needs therapeutic treatment.

The utility model summary of the invention

The purpose of this utility model is exactly the weak point in the background technology, designs the electric pick damping device of the vibration sense of a kind of effective minimizing workman when the operation electric pick.

For achieving the above object, the utility model adopts following technical scheme: the electric pick damping device, comprise the electric pick body, pivoted housing, assist handle and operating part, the pivoted housing left end is connected with the electric pick body, assist handle is connected with the pivoted housing right-hand member, operating part one end is positioned at pivoted housing, pivoted housing is provided with spring vibration damper, described spring vibration damper comprises plastic bushing, spring, circlip, spring housing are located at outside the pivoted housing, and plastic bushing is set in outside the spring, the interior ring muscle of plastic bushing left end and pivoted housing outer wall coupling, pivoted housing is provided with annular groove near the outer wall of plastic bushing right-hand member, and circlip is positioned at annular groove, and spring is between interior ring muscle and circlip.

For a kind of optimization of the present utility model, described circlip external diameter and plastic bushing internal diameter coupling.

The utility model is compared with background technology, has reaction force and vibrations when absorbing the electric pick operation effectively, reduces the harmful effect of reaction force to the user, makes work tired time lengthening occur, thereby has improved operating efficiency.
