Problems solved by technology

[0004] Since there are many kinds of tools and molds in the foundry, the claw hammer and wrench are small in size, and workers often throw them away after use, and they often cannot find them. Moreover, claw hammers and wrenches are often used at the same time to correct the same wax model. Two different tools are scattered in different places, and it is time-consuming to find and use, which reduces work efficiency

Embodiment

[0017] Example: such as figure 1 As shown, a new type of claw hammer includes a handle and a hammer body 3. The handle adopts a detachable design and is divided into two parts, the front handle 1 and the rear handle 2. One end of the front handle 1 is fixedly connected with the hammer body 3, and the front The handle 1 and the rear handle 2 are flat and hollow structures. The surfaces of the front handle 1 and the rear handle 2 are provided with multiple forks 4 for rotating the screw cap. The front handle 1 and the rear handle 2 are connected by threads, and the tail end of the front handle 1 has The protruding part 6 extending out of the body is provided with an external thread on the outside of the protruding part 6, and the middle position of the protruding part 6 is fixed with a screwdriver rod 7, the tail of the screwdriver rod 7 is connected to the screwdriver head 8, and the rear handle 2 is connected to the front handle 1. The inner wall of the opening at one end is p...

Abstract

The invention relates to the field of hardware tools, in particular to a novel claw hammer which can be used for rotating a screw cap. The novel claw hammer comprises a handle and a hammer body, wherein the handle adopts a detachable design for being detached into front and rear parts, which are respectively a front handle and a rear handle; one end of the front handle is fixedly connected with the hammer body; both the front handle and the rear handle are flat hollow structures; and a plurality of forks are formed in the surface of the front handle and the surface of the rear handle for rotating the screw cap. According to the novel claw hammer, a hammering function of the claw hammer and a screw cap rotating function of a wrench are combined together, so that the design is delicate and the structure is reasonable; the conventional claw hammer is improved to achieve the dual-use effect, so that a wax repair worker can use one tool to complete two different kinds of work; and moreover, the novel claw hammer is user-friendly, and reduces potential safety hazard to the greatest extent.

Description

technical field [0001] The invention relates to the field of hardware tools, in particular to a novel claw hammer which can be used to rotate screw caps. Background technique [0002] Casting is one of the basic processes of modern machinery manufacturing industry. As a metal thermal processing technology, casting has gradually matured in my country. Foundry machinery is to use this technology to smelt metal into a liquid that meets certain requirements and pour it into the mold. After cooling, solidification, and cleaning, all the mechanical equipment that can be used to obtain castings with predetermined shape, size and performance, Also known as casting equipment. [0003] Generally speaking, the production process of foundry machinery can be roughly divided into wax pressing, shell making, pouring, post-processing, and inspection. The specific operation is to correct the wax model is to repair the wax. In the casting factory, workers use a lot of tools to repair the w...
