DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 4 As shown, Example 1, a high-rise adjustable height drilling tool without a frame, includes a vertical connecting column 2, the upper part of the vertical connecting column 2 cooperates with the motor, the lower part of the vertical connecting column 2 is hinged with an adjusting rod 6, the middle part of the adjusting rod 6 is hinged with a fixed column 18, the upper part of the fixed column 18 is hinged with a connecting rod 5, the connecting rod 5 is arranged parallel to the adjusting rod 6 and the other end of the connecting rod 5 is hinged on the vertical connecting column 2, the vertical connecting column 2 is connected to the fixed column 18 through the adjusting rod 6 and the connecting rod 5 to form a variable quadrilateral structure, and the vertical connecting column 2 and the fixed column 18 are provided with a number of adjustment holes 4 that cooperate with the adjusting rod 6 and the connecting rod 5 respectively. The middle portion of the adjustment rod 6 is hinged to the fixed column 18. Pressing down one end of the adjustment rod 6 causes the other end of the adjustment rod 6 to move the vertical connecting column 2 upward. The vertical connecting column 2 and the fixed column 18 are hinged via the connecting rod 5, ensuring that the vertical connecting column 2 is always in a vertical state, thereby enabling the electric drill to drill holes in high-rise structural columns, avoiding the cost of erecting a frame and improving drilling efficiency. The adjustment holes 4 provided on the fixed column 18 and the vertical connecting column 2 can be used to adjust the connection height between the vertical connecting column 2 and the fixed column 18, thereby adjusting the height of the electric drill, achieving multiple height adjustments and expanding the scope of application of the drilling tool without erecting a frame.

[0026] In this embodiment, the upper part of the vertical connecting column 2 is provided with a mounting bracket 1 that cooperates with the electric drill and a buckle 3 for fixing the electric drill wire. The buckle 3 can be a stainless steel buckle 3 or a cable tie, which is used to fix the connecting wire of the electric drill to prevent the electric drill from being offset on the mounting bracket 1 due to pulling the wire during construction, thereby affecting the drilling effect. The mounting bracket 1 is preferably a U-shaped bracket. The mounting bracket 1 is fixed to the upper part of the vertical connecting column 2, and the top of the mounting bracket 1 is flush with the top of the vertical connecting column 2. The electric drill is fixed to the vertical connecting column 2 by a cable tie or rope and is located in the mounting bracket 1. The mounting bracket 1 is used to support the electric drill to prevent the electric drill from sliding down during use and affecting the drilling effect. The upper part of the vertical connecting column 2 is provided with a transparent protective cover that cooperates with the electric drill. The transparent protective cover is a conical cover arranged under the electric drill. The conical cover is used to receive dust emitted by the electric drill to prevent the dust from entering the eyes of the construction workers below.

[0027] In this embodiment, both ends of the connecting rod 5 are provided with a bolt 1 5-1, which is rotatably mounted on the corresponding fixed column 18 or vertical connecting column 2. The bolt 1 5-1 passes through the corresponding adjustment hole 4 and is threadedly connected to the limit nut. The adjusting rod 6 is provided with a bolt 2 6-1, which is rotatably mounted on the corresponding fixed column 18 or vertical connecting column 2. The bolt 2 6-1 passes through the corresponding adjustment hole 4 and is threadedly connected to the limit nut. Bolt 1 5-1 and bolt 2 6-1 can also use a 14-diameter tie rod, and the limit nut can be a butterfly nut. The tie rod is inserted into the corresponding adjustment hole 4 to realize the rotational connection between the connecting rod 5 and the adjusting rod 6 and the corresponding vertical connecting column 2 and the fixed column 18. Then, through the principle of leverage, pressing the adjusting rod 6 downward drives the vertical connecting column 2 to move upward, thereby realizing the electric steering upward movement, thereby realizing the drilling of the top structural column.

[0028] Specifically, the vertical connecting column 2, fixed column 18, adjustment rod 6, and connecting rod 5 can all be made of scrap timber. Embracing the concept of waste reuse, the main structure is composed of scrap timber, assembled from timber of varying lengths and four 14-diameter pairs of wire drawing and butterfly buckles to form a movable parallelogram. An electric drill is secured to the top of the timber with wire, and the socket and electrical cord are secured in place. Two people move the drill up and down, allowing the height to be adjusted. Pads can also be added to the bottom for height adjustment. This tool is simple to make and easy to operate, turning waste into valuable resources, and can achieve the purpose of drilling without the need for a frame.

[0029] like Figure 3As shown, embodiment 2 is a high-rise adjustable height drilling tool that does not require a frame, and the lower part of the fixed column 18 is connected to a base 7. The base 7 supports the fixed column 18. The base 7 increases the contact area between the fixed column 18 and the floor or the ground, which can prevent the device from causing damage to the ground during use, and also improves the stability of the device. The base 7 can be further preferably selected, and the lower part of the base 7 is connected to a self-locking universal wheel 8. At least three self-locking universal wheels 8 are installed at the lower part of the base 7. The self-locking universal wheels 8 are universal wheels that can be purchased on the current market. Installing the self-locking universal wheels 8 at the lower part of the base 7 facilitates moving the device to a designated position, improves the moving efficiency, and saves workers' physical strength.

[0030] In this embodiment, a foot control assembly is hinged on the adjustment rod 6. The presence of the foot control assembly can free up manual labor, allowing only one person to complete top drilling. Specifically, one hand is placed on the vertical connecting column 2, and the other hand can be placed on the fixed column 18 to assist in positioning. Then, one foot drives the adjustment rod 6 through the foot control assembly, and through the adjustment rod 6, drives the vertical connecting column 2 upward, so that the electric drill reaches the designated position and starts drilling. When the switch is installed on the vertical connecting column 2, the switch can be manually turned on and off to complete positioning and drilling by one person, reducing labor costs and increasing efficiency. The foot control assembly includes a connecting rod 9 and a foot pedal 10. One end of the foot pedal 10 is hinged to the base 7, and the other end of the foot pedal 10 is hinged to the adjustment rod 6 through the connecting rod 9. Pressing the foot pedal 10 downward drives the adjustment rod 6 downward through the connecting rod 9, thereby moving the vertical connecting column 2 upward and driving the electric drill upward to the designated position. Control is convenient and one person can operate it.

[0031] The other structures are the same as those in Example 1.

[0032] like Figure 4 As shown, Example 3 is a high-rise adjustable height drilling tool that does not require a frame. The foot control assembly includes a control rod 15, and the middle part of the control rod 15 is hinged with a pillar 16, and the pillar 16 is fixedly connected to the base 7. One end of the control rod 15 is connected to a foot plate 17, and the other end of the control rod 15 is hinged with a lifting rod 1411, and the other end of the lifting rod 1411 is hinged with a transition rod 12, and the transition rod 12 is hinged with the pillar 2 13 connected to the base 7, and the transition rod 12 is connected to the adjustment rod 6 through the pull-down rod 19. The support 16 is fixedly connected to the base 7. The control rod 15 hinged on the support 16 is connected to the transition rod 12 through the lifting rod 1411. The transition rod 12 is connected to the adjustment rod 6 through the pull-down rod 19. The control rod 15, in cooperation with the transition rod 12, pulls down the adjustment rod 6 and can adjust the control angle within a certain range, making it convenient to perform footwork when controlling the vertical connecting rod 5 and the fixed rod. The foot plate 17, the control rod 15 and the adjustment rod 6 also adopt the lever principle, which is more labor-saving.

[0033] The other structures are the same as those in Example 2.
