Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering more particularly, relate to a kind of building construction concrete wall surface drilling device. BACKGROUND

[0002] Concrete wall surface drilling device is a tool specially used for drilling on concrete wall surface, which usually includes a drill rig, a drill bit and other necessary accessories, for creating holes of different diameters and depths on concrete wall surface. This device is suitable for construction, decoration, maintenance and other occasions where it is necessary to install fixtures or arrange lines on concrete wall surface.

[0003] However, the existing drilling device has the following problems when in use:

[0004] The drill rod is usually placed in a tool bag or tool box. During drilling, the corresponding drill rod needs to be frequently taken out from the tool box or tool bag according to different needs. Each time the appropriate drill rod needs to be selected from a large number of tools by the construction personnel, which not only interrupts the continuity of the drilling operation, but also reduces the overall construction efficiency. Moreover, this frequent taking and placing operation breaks the smoothness of the drilling work. The construction personnel need to stop working and find the appropriate drill rod during the drilling process, and then return to the drilling position to continue the operation. During this process, the work rhythm of the construction personnel is disrupted, which may affect the drilling accuracy and quality. In addition, the frequent standing up and bending down to take the drill rod will increase the physical fatigue of the construction personnel and reduce the work efficiency.

[0005] The utility model can quickly and easily replace drill rods of different specifications by the construction personnel, without the need for tedious searching and taking in the tool bag as in the traditional way, thereby greatly saving the drill rod replacement time. UTILITY MODEL CONTENTS
