[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0022] In the utility model, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0023] like Figure 1 and Figure 2 As shown, the utility model provides an impact drill bracket, comprising: an impact drill bracket 1, a lifting rod 2 and a base 3, the top end of the lifting rod 2 is connected to the impact drill bracket 1, and in order to ensure the stability of the connection between the two, it is preferably welded, and the bottom end of the lifting rod 2 is fixedly installed on the base 3;

[0024] The lifting rod 2 is used to support the impact drill bracket 1 and provide an upward force to facilitate the impact drill to drill holes. The lifting rod 2 includes a hollow main rod 21, and a secondary rod 22 is inserted into the main rod 21. The secondary rod 22 can be freely lifted and lowered in the main rod 21. The top of the secondary rod 22 is fixedly connected to the impact drill bracket 1, and the bottom of the main rod 21 is welded and fixed to the base 3, and a lifting member for driving the secondary rod to rise is provided in the main rod 21. The lifting member can be a spring, a structural member of a screw nut substructure, or a structural member of a rack and a gear, which is used to provide an upward force for the secondary rod 22, so that workers can operate the impact drill to drill holes on the ground.

[0025] Among them, the working state of the impact drill can be controlled in many ways:

[0026] The external switch of the impact drill is connected to the construction personnel on the ground;

[0027] Fix the button switch on the impact drill with tape or the like to keep it in the on state, and then indirectly control the working state of the impact drill by controlling the on and off of the power supply;

[0028] A retractable component is installed on the impact drill bracket so as to abut against the switch of the impact drill, and a control switch of the retractable component is arranged at the ground operator.

[0029] The impact drill bracket provided by the utility model can fix the impact drill at the top to perform hole opening construction without the need to set up scaffolding or ladders, thereby reducing the construction difficulty; and the utility model has a simple structure, is easy to operate, saves costs, and is safe to use.

[0030] In order to simplify the lifting structure and reduce the manufacturing cost, the further improvement of the technical solution is that the lifting member includes a spring arranged in the main rod 21. The spring provides an upward force for the secondary rod 22. At the same time, opposite waist-shaped holes can be opened on the main rod 21, and a cross bar passing through the waist-shaped holes is provided on the secondary rod 22. The construction personnel can pull down the cross bar to make the secondary rod 22 descend.

[0031] A further improvement is that a window 23 is provided on the main rod 21, and a scale 24 is provided at the position of the window 23. At the same time, a marking point or a corresponding mark 221 is provided on the secondary rod 22. The drilling depth of the impact drill can be observed through the marking point or the corresponding position of the mark on the scale, so as to accurately control the drilling depth.

[0032] A further improvement is that the window 23 is L-shaped, and a mark 221 passing through the window 23 is provided on the secondary rod 22. In the working state, the mark 221 can be stuck in the transverse groove of the L-shaped window 23 to limit the position, so that the impact drill is in a lower position, which is convenient for it to move to the punching position. After the belt moves to the punching position, the secondary rod 22 is rotated so that the secondary rod 22 rises under the action of elastic force, thereby making the impact drill bit against the punching position.

[0033] A further improvement is that a universal wheel 31 is installed at the bottom of the base 3 to facilitate the movement of the bracket, and a brake is provided on the universal wheel 31 to ensure that it does not shake or move in the working state.

[0034] A further improvement is that a hand-holding rod 32 is provided on the base 3, so that the construction personnel can hold the support when moving the bracket, and the impact drill working state control switch can be integrated on the hand-holding rod 32. In addition, for easy storage, the hand-holding rod 32 can be designed as a foldable handrail, which can be folded and stored through the bottom rotating shaft.

[0035] In order to further optimize the base structure and make it more stable and reliable, the technical solution is further improved as follows: the base 3 includes a top plate 33, a base bracket 34 and a bottom plate 35, the top end of the base bracket 34 is connected to the top plate 33 by a rotating shaft, the top plate 33 is fixedly connected to the bottom end of the lifting rod 2, and the bottom end of the base bracket 34 is arranged on the bottom plate 35.

[0036] As a further improvement, the base support 34 includes three legs 341 arranged in a triangle to improve its stability.

[0037] As a further improvement, the support leg 341 is composed of two sections connected by threads, and the length of the support leg 341 can be adjusted by a knob, thereby preventing the impact drill from being non-perpendicular to the drilling surface due to uneven ground.

[0038] As a further improvement, a level 36 is provided on the base support 34 for observing the verticality of the impact drill and the drilling surface, and in combination with the adjustable length legs 341, the verticality of the impact drill and the drilling surface can be ensured.

[0039] As a further improvement, the impact drill bracket 1 is provided with a slot for limiting the position of the impact drill, the slot matches the overall shape of the impact drill for better fixation, and a strap for fixing the impact drill is provided on the slot.

[0040] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
