The utility model is a manual hole puncher, has low cost, does not need to be electrified, and can be used in narrow construction positions, rainy days or humid environments; meanwhile, the construction efficiency is improved, the application range is enlarged, and the defects of limitation of hole opening specifications, inconvenience in operation and the like are overcome.
Description
Technical Field
The utility model belongs to the technical field of the construction, in particular to template hole digger.
Background
In civil construction, a large number of reinforced concrete wall, column and beam side formworks need to be reinforced by using split bolts during construction, so that the formworks need to be perforated to be threaded with the split bolts. When the wall body formwork is matched with a formwork, the formwork needs to be perforated according to the requirements of a construction scheme, but when a few of plates are replaced without the number of moles or a few of plates are replaced, the formwork needs to be temporarily perforated, and due to the fact that split bolt holes need to be formed to penetrate through split bolts to reinforce the formwork, wall, column and beam side face formworks, the perforating processes are a few and wide in range.
The conventional tapping is generally made by using an electric tool tapper or a simple tapper made by welding a drill bit at one end of a steel bar. When the electric appliance perforator is used, an electric box and a cable need to be equipped, so that investment is large, energy is wasted, the using environment, the using place and the using position are greatly limited, and certain defects are provided from the economic perspective, the field power utilization safety perspective and the portable perspective. And steel bar welded formula's simple and easy hole digger, in-service use, the drilling operation is inconvenient, and the drill bit is welded fastening on the dowel bar moreover, and then the trompil specification is limited, and to a great extent can not satisfy the size of various trompils, and the trompil is too big, can appear leaking thick liquid phenomenon, and the trompil is less can appear the piping and can not pass phenomenons such as past.
Disclosure of Invention
The utility model aims at providing a convenient to use, low cost do not receive the template hole digger of service environment restriction.
Therefore, the technical scheme of the utility model is that: a template tapper, comprising: comprises a tubular main body, wherein a drill bit is fixed at the front end of the main body, and an L-shaped rotating handle is vertically fixed at the rear end of the main body; the main body is sleeved with a connecting sleeve, and a fixed handle is arranged below the connecting sleeve; the L-shaped rotating handle drives the main body to rotate in the connecting sleeve.
Furthermore, the front end of the drill bit is of a sawtooth structure, the rear end of the drill bit is provided with an external thread, the front end of the tubular main body is provided with an opening, an internal thread is arranged in the opening, and the drill bit is fixedly connected with the tubular main body through the thread.
Furthermore, the L-shaped rotating handle comprises a rotating connecting rod and a rotating handle which are vertically arranged, the rotating connecting rod is vertically fixed with the main body, and a first anti-skidding sleeve is sleeved on the rotating handle.
Furthermore, fixed handle is L type structure, including the fixed link and the fixed handle of perpendicular setting, the fixed link vertical fixation is on connecting sleeve, and the cover has the second antiskid cover on the fixed handle.
The utility model discloses during the use, hold fixed handle, support the drill bit behind the position that needs punched, rotate rotatory handle for the drill bit is rotatory the back, utilizes the sawtooth structure to punch. Through threaded connection between drill bit and the tubular main part, both are connected firmly, and can punch as required the size, change corresponding drill bit, satisfy various trompil demands.
The utility model is a manual hole puncher, has low cost, does not need to be electrified, and can be used in narrow construction positions, rainy days or humid environments; meanwhile, the construction efficiency is improved, the application range is enlarged, the defects of limitation of opening specifications, inconvenience in operation and the like are overcome, the on-site use effect is good, the assembly is simple, the disassembly is convenient, and the storage, the packaging and the transportation are convenient.
Drawings
The following detailed description is made with reference to the accompanying drawings and embodiments of the present invention
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural diagram of the drill bit of the present invention.
Labeled as: the drilling tool comprises a tubular main body 1, a drilling bit 2, a sawtooth structure 21, external threads 22, a rotary connecting rod 3, a rotary handle 4, a first anti-slip sleeve 5, a connecting sleeve 6, a fixed connecting rod 7, a fixed handle 8 and a second anti-slip sleeve 9.
Detailed Description
See the drawings. The embodiment comprises a tubular main body 1, wherein the front end of the tubular main body 1 is provided with an opening, an internal thread is arranged in the opening, the front end of a drill bit 2 is of a saw-toothed structure 21, the rear end of the drill bit is provided with an external thread 22, and the drill bit 2 is fixedly connected with the tubular main body 1 through the thread. The rear end of the tubular main body 1 is vertically fixed with an L-shaped rotating handle, the L-shaped rotating handle comprises a rotating connecting rod 3 and a rotating handle 4 which are vertically arranged, the rotating connecting rod 3 is vertically fixed with the tubular main body 1, and the rotating handle 4 is sleeved with a first anti-skidding sleeve 5. The middle of the tubular main body 1 is sleeved with a connecting sleeve 6, a fixed handle is arranged below the connecting sleeve 6, the fixed handle is of an L-shaped structure and comprises a fixed connecting rod 7 and a fixed handle 8 which are vertically arranged, the fixed connecting rod 7 is vertically fixed on the connecting sleeve 6, and a second anti-skidding sleeve 9 is sleeved on the fixed handle 8.
When the drilling tool is used, the fixed handle is held, the drill bit 2 is abutted to a position needing drilling, then the rotating handle is rotated, the rotating handle drives the tubular main body 1 to rotate in the connecting sleeve 6, and the sawtooth-shaped structure 21 of the drill bit 2 is used for drilling.
