Novel square sleeve electric pick

Abstract

The invention discloses a novel square sleeve electric pick, and relates to the field of electric picks. A front cylinder is arranged at the front end of an electric pick body, a guide column is arranged in the front cylinder, an auxiliary hammer is arranged at the rear end of the guide column, a piston is arranged at the rear end of the auxiliary hammer, the auxiliary hammer and the piston are arranged in an air cylinder, a first damping ring is arranged at the joint of the air cylinder and the guide column, a first spring is installed on the side of the guide column, one end of the guide column is installed in a square sleeve, an impactor is arranged in the square sleeve, the guide column is arranged on the rear portion of the impactor, a second spring is clamped and fixed to the joint, and a chuck device is arranged at the front end of the square sleeve. The novel square sleeve electric pick is reasonable in structural design, easy to install and convenient to use, unpredictable bounce of the auxiliary hammer is eliminated by installing a second damping ring and the spring in front of the auxiliary hammer, and the problems of hammer breaking and continuous punching are solved by reserving space through the forward pushing and loosening design of the square sleeve chuck device.

Description

Technical field: [0001] The invention relates to a novel square set electric pick, which belongs to the technical field of electric picks. Background technique: [0002] The electric pick is a double-insulated hand-held electric tool powered by a single-phase series-excited motor. It has the characteristics of safety, reliability, high efficiency, and convenient operation. For facility construction and other construction projects, it is suitable for pickaxes or other appropriate accessories, such as chisels and shovels, for crushing, chiseling, digging, grooving, cutting and other operations on concrete, masonry structures and asphalt pavements. [0003] At present, the electric picks with square pick tips on the market are generally solved by the square sleeve telescopic principle of the electric hammer. It is easy to be damaged. The size and price of the square head and the hexagonal head are different, and the working principle is also different. The retractable structur...

Problems solved by technology

[0003] At present, the electric picks with square pick tips on the market are generally solved by the square sleeve telescopic principle of the electric hammer. It is easy to be damaged. The size and price of the square head and the hexagonal head are different, and the working principle is also different. The structure of the square sleeve is easy to break and easy to leak. Using the principle of electric pick, the drill bit with electric hammer is ideal, but There is a problem that it is easy to break the hammer if you don't hit it continuously, and you will continue to hit it if you keep hammering
