Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of handheld tools, and in particular to a level for handheld tools. Background Art
[0002] In daily production and construction, we often use handheld tools for processing, such as hand drills and handheld cutting machines. These tools play an important role in various industrial and construction fields due to their portability and flexibility.
[0003] However, when it comes to using handheld tools for work, we find it difficult to ensure that these tools are accurately grasped on the reference surface to be processed based solely on the technician's experience and intuition. For example, when performing operations such as drilling or cutting, due to the obstruction of the tool body, we cannot intuitively judge the cutting angle of the drill bit or cutting saw blade, which leads to errors in the processing angle and affects the processing accuracy. The use of advanced laser positioning instruments is costly, and the auxiliary instruments greatly increase the weight of the handheld tools and reduce the convenience of operation. To this end, we propose a level for handheld tools. Summary of the invention
[0004] The purpose of the present invention is to solve the problem that when using hand-held tools for operations, we find it difficult to ensure that these tools are accurately grasped on the reference surface to be processed only by the experience and intuition of technicians. For example, when drilling or cutting, due to the obstruction of the tool body, we cannot intuitively judge the cutting angle of the drill bit or cutting saw blade, which leads to errors in the processing angle and affects the processing accuracy. The use of advanced laser positioning instruments is costly, and the auxiliary instruments greatly increase the weight of the hand-held tools and reduce the convenience of operation. The present invention provides a level for hand-held tools.
[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:
[0006] A level for handheld tools comprises a level fixing frame, a universal bubble level is fixedly connected to the front side of the level fixing frame, a vertical fixing seat is fixedly connected to the upper center of the level fixing frame, and a cylindrical bubble level is fixedly connected to the upper end of the vertical fixing seat, the cylindrical bubble level is perpendicular to the front plane of the universal bubble level, and a docking fixing mechanism is fixedly connected to one side of the level fixing frame.
[0007] Furthermore, the docking and fixing mechanism comprises an equipment fixing collar, and an embedded nut is embedded on a side of the equipment fixing collar away from the level fixing frame, and a fastening screw is threadedly connected to the inner and outer sides of the embedded nut.
[0008] Furthermore, one end of the fastening screw away from the equipment fixing collar is fixedly connected to the butterfly head.
[0009] Furthermore, the upper end of the vertical fixing seat is fixedly connected to a fixing seat at the front and rear ends, and the fixing seat at both ends is fixedly connected to a compression gasket on the inner side.
[0010] Furthermore, a circular groove is provided at the center of the front surface of the level fixing frame, and the circular groove is adapted to the size of the universal bubble level.
[0011] Furthermore, an aluminum foil reflective film is attached to the bottom of the circular groove of the level fixing frame and the upper end of the vertical fixing seat.
[0012] The beneficial effects of the present invention are as follows:
[0013] 1. The present invention provides a docking and fixing mechanism, which is convenient for disassembly and assembly of equipment and can be used according to needs. When the processing reference surface is horizontal or vertical, the docking and fixing mechanism is connected to the body of a hand-held tool, such as an electric drill or an electric saw, to keep the universal bubble level or the cylindrical bubble level parallel to the processing reference surface. By observing the water droplets on the universal bubble level and the cylindrical bubble level, during the processing, by judging and observing the positions of the water droplets in the universal bubble level and the cylindrical bubble level, the relative stability of the hand-held tool and the processing reference surface is maintained, thereby improving the processing accuracy. The setting of the universal bubble level and the cylindrical bubble level can assist the processing personnel in making judgments, thereby improving the processing accuracy and reducing the requirements for processing experience. In addition, the production and use costs of the universal bubble level and the cylindrical bubble level are low, thereby facilitating their popularization and use.
[0014] 2. The butterfly-shaped head of the present invention facilitates manual rotation of the fastening screw.
[0015] 3. The aluminum foil reflective film provided in the present invention can improve the backlight brightness of the universal bubble level and the cylindrical bubble level, thereby facilitating the observation of the universal bubble level and the cylindrical bubble level.
