After the structure is adopted, the vibration-damping electric hammer and the electric pickax have the advantages of simple and reasonable structure, labor-saving, light and convenient construction, good vibration-damping effect, high efficiency, long service life, high stability and reliability and the like.

Description

Damping electric hammer and electric pick

Technical field

The utility model relates to a kind of impact type electric driven instrument, the particularly a kind of damping electric hammer and electric pick that can alleviate recoil.

Background technology

Electric hammer and electric pick are a kind ofly to be used for excavating various bases, cement pavement, highway pavement specially, to crack impact type electric driven instruments such as stone; Its advantage is that power is big, power output is stable, impulsive force is strong, efficient is high, easy to use; Must equally with pneumatic pick not draw heavy tracheae, and receive liking of numerous workmens deeply.But in use needing the workmen to exert pressure with hand, electric hammer and electric pick could produce impulsive force; Body also produces very big recoil when producing impulsive force; This recoil acts directly on the workmen through operating grip, so not only needs bigger physical consumption, very easily causes work fatigue at short notice; And directly influence operating efficiency, even jeopardize the healthy of workmen.To above-mentioned situation, many manufacturers and knowledgeable people have carried out R and D, have developed the damping electric hammer and the electric pick of all styles of, but there are problems such as complex structure, service life weak point, manufacturing cost height in most damping electric hammer and electric pick; Therefore, develop a kind of convenience simple in structure, damping electric hammer and electric pick safe and practical, long service life are extremely urgent problems.

Summary of the invention

For overcoming the above-mentioned deficiency that existing damping electric hammer and electric pick exist, the purpose of the utility model provides laborsaving light, the good damping effect of a kind of simple and reasonable, construction, long service life, reliable and stable damping electric hammer and electric pick.

The utility model solves the technical scheme that its technical problem adopted; It comprises pick chuck, body, handle set, handle, and handle set is fixed on the body back seat, and the bottom of said handle is movably articulated on the handle set; The top of handle set is provided with two guide pillars that are connected as a single entity; Guide pillar is provided with the spring support that can slide above that, and spring support is hinged on the fixed leg on handle top, between spring support and body back seat, is provided with damping spring; Damping spring one end is positioned on the protruding location of body back seat, and the other end is arranged in the spring cavity of spring support.

The further scheme of the utility model, the junction, top of said handle set and handle is arranged with the damping sheath, and damping sheath one end is buckled on the spring support, and the other end is buckled on the handle set through damping sheath pressure board.

The further scheme of the utility model is arranged with the damping washer that matches with spring support on the described guide pillar.

After adopting said structure; With following advantage of prior art and effect: the one because spring support is slidingly arranged on the guide pillar; Spring support is hinged on the fixed leg, guarantees the damping spring longitudinal stress, so not only can play cushioning effect to greatest extent; And each connector reasonable stress, can increase the service life greatly; The 2nd, owing to receive the effect of damping spring, damping washer and damping sheath, handle can significantly reduce recoil, can effectively improve impact resistance and damping effect; The 3rd, because spring support is arranged between two guide pillars, stressed even, good operating stability is used more steadily reliable.
