Abstract

PURPOSE: A vertical guiding device for a hand drill for two persons is provided to enable a worker to accurately and properly drill a hole in a stable state according to a drilling condition. CONSTITUTION: A pushing shaft is assembled into the body of a hand drill. A spring pipe(17) and a movable main pipe(15) are attached onto a body of the drill and a compressing bolt(12) is attached onto a spring compressed plate. A spring(14) is inserted into the spring pipe and drilled together. A guiding bar(16) is inserted into the movable main pipe and a cover(13) is inserted into the upper end of the guiding bar. The guiding bar is fixed to a stand(21) by bolts and nuts. Supporting bars(22) are vertically installed in front of the stand triangularly. When the drill is unstable, sensing bolts of the supporting bars are operated to light a bulb. Therefore, a worker checks the drilling position and corrects the position by the naked eyes.

Description

Two-handed hand drill guiding device {omitted}

(1) the technical field to which the invention belongs and the prior art in that field

The present invention relates to a two-handed hand drill, in particular, to improve the drillability by making it easy to drill holes in a stable state when drilling with several types of drill processing objects at the construction site using the hand drill. A vertical guide of a hand drill.

In general, in the construction site or workpiece shaping site, it is impossible to drill by installing a high-speed drill device.

One example is shown in FIG. 1 because it is difficult for a worker to hold the drill at a right angle and hold the drill at a right angle during drilling, and it is difficult to securely hold the drill and to make a precise hole. A support groove formed on the middle bottom of the lever 3 by connecting the lever 3 to the other side of the chain 2 connected to the hook by hooking the hook 1 to While holding the lever 3 in the state supported by (4), the drill handle was held by holding the drill handle.

By the way, when drilling by the method described above while maintaining the angle of the drill while pressing the lever (3) in the vertical direction, the drill workability was not very good because the drill itself does not maintain a stable state in the vertical state. Not only was there a problem in that the hole was not accurately drilled, but there was a problem in that the work was not properly made in response to the drilling work situation of the object to be drilled.

(2) Technical problem to be invented

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to enable a drill operation in a stable state by using a hand drill so that the correct hole can be drilled and appropriately suited to the drill operation situation of the drilled object. It is to provide a vertical guide device for one drill that enables the worker to perform efficient drill work for a long time by making the drill work easier in response. The vertical guide device of the hand drill of the present invention for achieving the above object is to assemble the pressing shaft in the rear of the hand drill body, and to press the pressing shaft with a separate lever to drill work, blocking the bottom of the spring pipe with a disc and moving the main pipe at the center. Drill a hole and fix the top of the moving main pipe to the bottom of the spring pipe, make a round iron plate according to the inner diameter of the spring pipe, drill a hole slightly larger than the moving main pipe in the center, and bolt it to the left and right edges of the hole and insert the spring into the spring pipe. Insert the top plate to block the top of the spring pipe, drill the hole on the top plate like the outer diameter of the main pipe, drill the compression bolts on the left and right sides of the hole, insert the guide column on the moving frequency pipe, fix the cover on the top with the cover on the top, and install the steel plate on the cover before and after the Buddha. Compression Bolt Drilled Compression Ball Fasten the knaps and fasten the handlebars vertically to the cutting drill body, insert the moving pipe into the cover, fix the cover with the bolts, fix the handlebars with the bolts, make the bolts at the bottom of the guide bar, and fix it with the nuts. Block the bottom of the spring pipe with the fabric on the opposite side, and move the main pipe vertically to the left and right of the spring pipe, fix the compression bolt on the circular plate from the center to the left and right, insert it into the spring pipe, insert the spring on it, and drill the compression bolt hole on the top plate to spring the top plate. Fix the pipe and insert the guide column on the left and right side of the moving main pipe, and fix the cover bolt on the left and right side of the guide bar, and insert the compression bolt between the cover and fix the cover bolt. To the left and right to move the main pipe Fix the pendulum hanging with bolts, and make bolts at the bottom of the guide column and insert them on the left and right sides of the seat.The seats are roughly T-shaped, and the support bar (pipe) is installed vertically under the front handle. Drill the sensory bolt holes, insert the spring into the pipe (support bar), and make the sensory bolt head round and insert it into the support bar (pipe), fix it with a nut on the top of the seat, and support the support bar (pipe) in the same way from the left and right of the opposite seat. Put the support bar (pipe) on the right and left at right intervals and insert the spring into the pipe by drilling the sensor bolt hole at the center of the support bar (pipe).

When the sensor bolts are inserted into the pipe and the nats are fixed on the seat, the support bar (pipe) adheres to the workpiece for the drill, but when the drill angle is changed, the two places the support bar (pipe) close to the workpiece. On the high side, the support bar (pipe) is opened from the workpiece, and the spring pressure pushes the sensor bolt toward the workpiece, and the power switch installed between the base and the sensor bolt is lit and the light bulb corresponding to the operation is activated. It is possible to fix and place the drill on the flat workpiece, then loosen both cover bolts and adjust the guide column up and down respectively. When giri approaches 2mm closer to the workpiece, tighten the cover bolts to position the workpiece as shown in Figure 2. Hook on and press the push shaft handle with the lever connected to the chain while compressing the spring And the pipe through the hole as the drill body move along the main guide is complete, hand drill vertical guide device to the desired city by spring pressure

(3) According to another aspect of the present invention, the processing of I-beams, etc.

When drilling the opponent deep, insert the seat bolts on the guides installed on the left and right guides in accordance with another embodiment of the present invention, and the guides on the opposite stable seats can be rotated 90 degrees. It is not possible to derail from the stable seat, and if you loosen the guide and turn the guide on the release prevention bolt, the seat and the stable seat will be disadvantaged.The drill will be crying on the I-shaped steel workpiece and the kaba bolt will be adjusted up and down. When the drill is normal to the stable seat, three support bars (pipes) are in close contact with the stable seat and two drill bars are inclined to the stable seat when the drill is normal to the stable seat. If the support bar (pipe) is open from the stable seat, the sensor bolt installed inside the support bar (pipe) The power switch installed between the seat and the sensor bolt is turned on by the spring pressure, and the light bulb corresponding to the position is turned on so that the operator can check and adjust it.

According to another embodiment, the water bottle hose, the water bottle air hose, and the drill body in order to prevent the water penetration of the drill body to install the air supply hose on the bottom of the water bottle to prevent abrasion due to heat of the nose to prevent the abrasion due to heat of the nose It is to provide a drill operation guide device that opens the cork installed with the gasket in the guide bar when the ministries work, and the old cow with the water installed on the base supplies water to the giri, and blocks the water by blocking the coke when the work is completed. .
