[0053] Specific embodiments: People use the breaking hammer designed by the present invention. Before use, the user manually pushes the trigger lever 12 to make the trigger lever 12 move downward; the downward movement of the trigger lever 12 will drive the drive plate 31 to move downward; the drive plate 31 moves downward to push the two driving blocks 36 to move downward; the downward movement of the two driving blocks 36 drives the two connecting blocks 35 to move downward; the downward movement of the two connecting blocks 35 drives the two trigger drive plates 9 to move downward Two trigger drive plates 9 move downwards to drive two connecting rods 25 to move downward; two connecting rods 25 move downward to drive two trigger plates 24 to move downward; two trigger plates 24 move downward to make the two The first block moves in the block groove opened on the sliding mounting block 8, and at this moment, the second limiting block 29 has just lost the limiting effect on the...

The invention belongs to the technical field of quartering hammers, and particularly relates to a quartering hammer with an adjustable handrail used in constructional engineering. The quartering hammer comprises a quartering hammer mechanism and a handrail mechanism, wherein the quartering hammer mechanism consists of a handle, a driving structure and a drill bit; the handle is mounted on the upper side of the driving structure; the drill bit is mounted on the lower side of the driving structure; the handrail mechanism is mounted on one side of the driving mechanism, and the handrail mechanismis matched with the handle. According to the quartering hammer disclosed by the invention, by manual adjustment of the handrail mechanism, a grab rail in the handrail mechanism can be moved to both sides of the quartering hammer so as to adapt to left and right hands of a user and avoid the inconvenience caused by the use of the quartering hammer by a user used to using the left hand; therefore,the quartering hammer is more convenient to use and can be used by a wider range of people.
Description
Technical field [0001] The invention belongs to the technical field of breaking hammers, in particular to a breaking hammer with adjustable handrails used in construction engineering. Background technique [0002] Breaking hammers can be widely used in construction fields such as metallurgy, mines, railways, highways, and buildings. They can be used for mining, crushing, and demolition of hard objects such as rocks, cement pavement, and old buildings. They can also be used for riveting by changing the drill rod. , Derusting, vibrating, compacting, piling and other specific operations, it has a wide range of uses. The traditional armrest of the breaker is installed on the right side of the handle; it is suitable for right-handed people, but it will feel particularly awkward when used by left-handed people; this reduces work efficiency; so It is very necessary to design a breaker that can be adapted to both left and right hands. [0003] The present invention designs a break...
