However, by fixing the hand drill stand on a fixed platform at a certain place, it lacks flexibility, especially when the round tube is fixed in space and cannot be moved. The existing hand drill stand is very inconvenient to use. For example, in some greenhouses built with galvanized round iron pipes as the frame, the frame needs to be drilled, or screws need to be driven in to connect the frame and the galvanized flat iron without holes. In this case, the galvanized round iron pipe cannot be moved, and it is difficult for the existing hand drill stand to complete drilling in this scenario.

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 ,in, Figure 1 A schematic diagram of the installation structure of the hand drill bracket and the hand drill provided by the utility model for convenient round pipe drilling; Figure 2 The overall structural diagram of the hand-held electric drill stand provided by the utility model for convenient round pipe drilling; Figure 3 A schematic cross-sectional view of the casing provided by the utility model; Figure 4 A schematic diagram of the structure of the fixing frame provided by the utility model; Figure 5 This is a schematic diagram of the partial structure of the fixing frame provided by the utility model.

[0022] In the specific implementation process, Figure 1-Figure 3 As shown, the hand drill bracket for convenient round tube drilling includes a ring frame installed at the output end of the hand drill 1, and both ends of the bottom of the ring frame are fixed with multi-stage telescopic sleeves, and a reset spring 2 is fixedly installed inside the sleeve, wherein the reset spring 2 is preferably a compression spring with good contraction and extension effects, and a fixing frame for fixing the round tube is also provided at the bottom of the sleeve.

[0023] The ring frame includes two opposite arc plates 9, which are connected by bolts, and the outer sides of the two arc plates 9 are fixed with connecting plates 10, and the bottoms of the two connecting plates 10 are fixedly connected to the connecting pipes 3 respectively;

[0024] It should be noted that the distance between the two arc plates 9 can be adjusted by tightening the bolts.

[0025] The sleeve includes a plurality of connecting tubes 3 nested in sequence, and the plurality of connecting tubes 3 are slidably arranged between them, wherein the two connecting tubes 3 located at the two end points are respectively fixedly connected to the bottom of the ring frame and the top of the fixing frame, and the two ends of the return spring 2 are respectively fixedly connected to the inner walls of the two connecting tubes 3 located at the two end points;

[0026] The inner walls of the multiple connecting tubes 3 have corresponding guide grooves, and the outer surfaces of the corresponding connecting tubes 3 have protrusions matching the guide grooves to ensure that the connecting tubes 3 do not separate. The multiple connecting tubes 3 will retract under the squeezing of the ring frame, thereby causing the hand drill 1 to move toward the direction of the round tube.

[0027] refer to Figure 4-5As shown, the fixed frame includes a fixed plate 4, two opposite movable plates 5, and a driving mechanism for driving the two movable plates 5 to move toward or away from each other at the bottom of the fixed plate 4. The fixed plate 4 is fixedly connected to the bottom of one of the connecting tubes 3. The bottom of the fixed plate 4 is provided with a slide groove 6 for the two movable plates 5 to slide. The driving mechanism is installed on the fixed plate 4. The inner side walls of the two movable plates 5 are provided with an arc plate 7 with a variable bending angle. One end of the arc plate 7 is fixed to the inner side wall of the movable plate 5, and the back of the other end of the arc plate 7 is also provided with a telescopic rod 8.

[0028] It should be noted that the back of the arc plate 7 is composed of a plurality of equidistantly distributed protrusions, the front of the arc plate 7 is a whole flexible plate, the flexible plate is integrally connected to the plurality of protrusions, and the telescopic rod 8 has a spring inside, which is used to drive the flexible plate to fit on the surface of the round tube. Since the force direction of the round tube when the electric drill 1 is drilling is the same as the long side direction of the movable plate 5, the bottom of the arc plate 7 is fixed during drilling, which can play a certain supporting effect. The other two arc plates 7 cooperate to better stabilize the round tube. The drill bit of the electric drill 1 and the bottom of the arc plate 7 can generate a relative squeezing force on the round tube through the fixation, so the two movable plates 5 do not need to clamp the round tube when moving, and only need to make the arc plate 7 fit on the surface of the round tube.

[0029] Specifically, the flexible board may be made of silicone or rubber.

[0030] The driving mechanism includes an adjusting rod 11, one end of which is rotatably mounted on the inner wall of the slide groove 6 through a bearing, and two threads with opposite spiral directions are respectively provided at both ends of the adjusting rod 11, and the two ends of the adjusting rod 11 are respectively threadedly connected to the two movable plates 5, and a turntable 12 is provided at one end of the adjusting rod 11, and a plurality of protrusions are fixedly connected to the edge of the turntable 12, and the protrusions can better rotate the turntable 12, and the rotation of the adjusting rod 11 can drive the two movable plates 5 to move toward or away from each other, so as to facilitate adjustment according to the size of the round tube.

[0031] The working principle provided by the utility model is as follows: when the bracket is used, the hand drill 1 is first placed between the two arc plates 9. The spacing between the two arc plates 9 can be adjusted by screwing the bolts to fix the hand drill 1. The two movable plates 5 can be driven to move toward or away from each other by rotating the adjusting rod 11, which is convenient for adjustment according to the size of the circular tube. Since the force direction of the circular tube by the hand drill 1 is the same as the long side direction of the movable plate 5 when drilling, the bottom of the arc plate 7 is fixed and can play a certain supporting effect when drilling. The other two arc plates 7 cooperate to better stabilize the circular tube. The drill bit of the hand drill 1 and the bottom of the arc plate 7 are fixed to generate a relative extrusion force on the circular tube to drill holes.

[0032] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0033] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
