The parallelogram frame is an equilateral quadrilateral frame.

The side length of the equilateral quadrangular frame is 400mm to 500mm.

The connection between the thrust rod of the percussion drill and the percussion drill is through a long hole capable of adjusting the position of the percussion drill.

The length of the ground support rod from the connecting pivot pin connected with the connecting rod with a rotating pressure handle to the support end of the ground support rod is 750mm to 800mm.

The ground support rod, impact drill thrust rod and connecting rod are square wood or aluminum alloy profiles with a side length of 50mm to 60mm.

A horizontal bar is fixedly arranged on the frame of the ground support rod of the parallelogram frame, and a length scale mark is arranged on the frame of the impact drill thrust rod of the parallelogram frame.

The beneficial effects of the utility model are: the utility model is simple in structure, easy to manufacture, and the positive effect produced in use is very obvious. Compared with an actual project: (the floor height is 2.8 meters), according to the original construction, the roof of the whole building has 5175 eyes, which takes about 35 working days and costs 5250 yuan. Use the utility model tool to share about 17 working days, cost 2550 yuan. If the floor height is higher, the amount of labor will be saved more. Therefore, the utility model is convenient for construction, saves labor costs and improves the efficiency by more than 50%, ensuring safety.

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

Detailed ways

Embodiment 1;

An embodiment of a quick tool for hole-piercing for roof planting bars, see Figure 1, the tool includes a percussion drill 1, and a connecting rod propulsion device is connected with the percussion drill, and the connecting rod propulsion device includes a one end acting on the ground 2 ground support rod 3, a percussion drill thrust rod 4 arranged in parallel with the ground support rod and at least two parallel connecting rods 5, one end of the percussion drill thrust rod is connected and fixed with the percussion drill, and two mutually parallel connecting rods The parallel ground support rods and impact drill thrust rods are connected together by four connecting shaft pins 6, and the connecting rod formed between the four connecting shaft pins and the ground support rod and impact drill thrust rod frame are a parallelogram frame 7 One of the two parallel connecting rods takes the connecting pivot pin connected with the ground support rod as the rotation axis point to extend outward a connecting rod to rotate the pressure handle 5-1. In order to increase strength and firmness, the number of parallel connecting rods may also be three or four.

The working method of the above structure is to press the end of the 8 pressure handle downwards. According to the principle of leverage, the connecting rod takes the connecting shaft pin connected with the ground support rod as the fulcrum, and the connecting rod drives the thrust rod of the impact drill to move upwards to realize the impact drill. Perforation of the top plate 9.

The connecting rods parallel to each other are divided into upper connecting rods and lower connecting rods, wherein a connecting rod extending outwards to rotate the pressure handle can be extended outwards from the upper connecting rods or from the lower connecting rods to Outwardly extending, the pressure handle used in this embodiment extends outward from the lower connecting rod, and the length of the pressure handle is 600mm to 650mm, which is the optimal control length.

The parallelogram frame can adopt various forms, such as a rectangular quadrilateral frame with equal opposite sides or an equilateral quadrilateral frame, and this embodiment adopts an equilateral quadrilateral frame.

When drilling, one hand presses the pressure handle, and the other hand holds the parallelogram frame. Therefore, as a person can control the best state, the side length of the equilateral quadrilateral frame is 400mm to 500mm. The optimum side length is 430mm.

In order to be able to adjust the distance between the impact drill and the top plate according to different floor heights, the connection between the impact drill thrust rod and the impact drill described in this embodiment is performed through the long hole 4-2 on the impact drill thrust rod that can adjust the position of the impact drill. Connection.

In order to be able to optimally control the connecting rod propulsion device, so that the controller can apply the maximum force to the pressure handle, therefore, the ground support rod is connected from the connecting shaft pin connected with the connecting rod with the rotating pressure handle to the supporting end of the ground support rod The length of the top is 750mm to 800mm.

The manufacture of this embodiment is very convenient, and materials can be obtained locally. The ground support rods, impact drill thrust rods and connecting rods are square logs with a side length of 50mm to 60mm, or aluminum alloy profiles. That is, when the floor height is not higher than 2.8 meters, the ground support rods, impact drill thrust rods and connecting rods are square wood with a side length of 50mm to 60mm, and aluminum alloy profiles are used when the floor height is greater than 3 meters.

Embodiment 2;

Another embodiment of a quick tool for hole-piercing for roof planting, see Figure 2 and Embodiment 1. In order to be able to control the actual drilling depth, the difference from Embodiment 1 is that a scale is provided in the connecting rod propulsion device, and the structure of the scale Yes: a horizontal bar 10 is fixedly arranged on the frame of the ground support rod of the parallelogram frame, and a length scale mark 11 is arranged on the frame of the impact drill thrust rod of the parallelogram frame. When the thrust rod of the impact drill moves upwards, the cross bar does not move, so that the depth of the hole can be read from the scale marks.

The positive effect of the above embodiment is very obvious in practice. Compared with an actual project: (the floor height is 2.8 meters), according to the original construction, the roof of the whole building has 5175 eyes, which takes about 35 working days and costs 5250 yuan. Use the utility model tool to share about 17 working days, cost 2550 yuan. If the floor height is higher, the amount of labor will be saved even more. the
