Problems solved by technology

But when using this lifting electric hammer, it is necessary to use a sufficiently high support to support the electric hammer, so there are more requirements for the construction supporting devices, otherwise the rack will be processed into a very long way to construct the ceiling, which will increase the cost of the present invention. Production difficulty

Embodiment 1

[0018] Such as figure 1 As shown, a hands-free electric hammer includes an electric hammer body 1, an electric hammer bracket 2, an exhaust pipe 3 made of steel pipe, a suction cup 4, a compression cover 5 and an electric hammer top spring 6, The suction pipe 3 is fixedly connected with the electric hammer bracket 2, the suction cup 4 and the compression cover 5 are connected to the same top end of the suction pipe 3, the suction cup 4 is made of silicon rubber, the compression cover 5 is made of steel, and the compression cover 5 is Funnel-shaped semi-open structure, the large end is open, and the small end is connected to the exhaust pipe 3. The opening of the compression cover 5 is provided with a radially extended lip plate 12, and the lip plate 12 is connected to the opening of the compression cover 5. The surface in the same direction as the mouth is provided with a friction strengthening structure, and the friction strengthening structure in this embodiment is a rubber ...

Embodiment 2

[0021] The suction cup 4 and the compression cover 5 are each two, and the top of the air extraction pipe 3 is provided with a connecting pipe. The two suction cups 4 are respectively connected to the two interfaces, and the two suction cups 4 are distributed axially symmetrically with respect to the exhaust pipe 3 . The friction enhancing structure is a composite fabric pad. All the other are with embodiment 1.

Abstract

The invention discloses a hand-free electric hammer. The hand-free electric hammer comprises an electric hammer body, an electric hammer bracket, a hard exhaust pipe, a sucker, a pressing cover and an electric hammer top spring; the exhaust pipe is fixedly connected with the electric hammer bracket; the sucker and the pressing cover are connected to the same end of the exhaust pipe; the pressing cover is a half-opened structure, and covers the sucker; the electric hammer body is slidingly connected to the exhaust pipe; an exhaust device is arranged in the exhaust pipe; and the electric hammer top spring is arranged between the tail end of the electric hammer body and the electric hammer bracket. The electric hammer can be absorbed and suspended on a ceiling through such structures as the exhaust pipe, the sucker and the pressing cover; and when the electric hammer is used for constructing the ceiling, operators have no need to hold the electric hammer with strength, so that the labor intensity in electric hammer construction is largely reduced, and the electric hammer construction efficiency and safety are improved.

Description

technical field [0001] The invention relates to a construction electric tool, more specifically, it relates to a hands-free electric hammer. Background technique [0002] Electric hammer, also known as impact electric drill, is a commonly used equipment in the field of construction. Its working method is a combination of impact and rotation, so that the drill bit gradually enters the wall or ground to break bricks, stones, cement and other materials. During the working process of the electric hammer, the vibration is extremely large. The operator will feel numbness and soreness in the arm when operating the electric hammer for a long time. In severe cases, it will even damage the muscles and bones, especially when the electric hammer is used to work vertically on the ceiling. The operator not only has to bear strong vibration, but also bears the pressure of the weight of the electric hammer, so the physical exertion is extremely great, and it is impossible to work for a long...
