Description

Technical Field

[0001] This utility model relates to the field of hardware tool technology, specifically a fixing fixture for drilling holes in hardware tools. Background Technology

[0002] Currently, drilling operations using hardware tools are usually carried out by combining an electric drill with a hole saw. Drilling operations using a hole saw are mainly used in fields such as construction engineering and fixture manufacturing.

[0003] Currently, some hole saws are typically stabilized by a worker holding an electric drill. However, if the surface of the workpiece is relatively smooth, the sudden high-speed rotation of the hole saw can easily cause it to slip on the workpiece surface. When the hole saw slips while drilling, not only is the safety compromised, but it can also easily cause scratches on the surface of the workpiece, thus affecting the aesthetics of the workpiece surface and even its subsequent use. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing fixture for drilling holes in hardware tools, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing fixture for drilling holes in hardware tools, comprising an electric drill body and a hole opener body installed at one end of the output shaft of the electric drill body, and further comprising:

[0006] A fixed ring is fixedly sleeved on the surface of the electric drill body. A collar is fixedly sleeved on the surface of the fixed ring. A movable plate slides through the surface of the collar. An anti-slip ring is fixedly connected to the surface of the movable plate. A reset mechanism is installed on the surface of the collar.

[0007] A groove is formed on the surface of the anti-slip ring. A C-shaped plate is fixedly connected to the inner wall of the groove. A rotating frame is rotatably connected to the inner wall of the C-shaped plate. A rotating shaft is fixedly connected to the top and bottom of the rotating frame. The rotating shaft rotates through the C-shaped plate. A reinforcing mechanism is provided inside the rotating frame. A slot is formed on the surface of the rotating frame.

[0008] Preferably, the reset mechanism includes a support plate, a reset plate, a guide rod, and a compression spring. The support plate is fixedly connected to the surface of the collar, the guide rod slides through the support plate, the reset plate is fixedly connected to the surface of the movable plate, one end of the guide rod is fixedly connected to the surface of the reset plate, and the compression spring is sleeved on the surface of the guide rod.

[0009] Preferably, the reinforcing mechanism includes an extension plate, a bolt, a threaded sleeve, and a reinforcing plate. The surface of the extension plate is slidably connected to the inner wall of the rotating frame. The bolt is fixedly connected to the surface of the extension plate and contacts the slotted inner wall. The threaded sleeve is threaded onto the surface of the extension plate and contacts the surface of the rotating frame. The reinforcing plate is fixedly connected to the surface of the extension plate.

[0010] Preferably, the top and bottom of the extension plate are fixedly connected to limit blocks, and the top and bottom of the inner wall of the rotating frame are provided with limit grooves, and the surface of the limit block is slidably connected to the inner wall of the limit groove.

[0012] Preferably, a connecting ring is fixedly connected to the surface of the movable plate, and the surface of the connecting ring is in contact with the surface of the collar.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When in use, the anti-slip ring increases friction by increasing the contact between the anti-slip ring and the workpiece surface, thus increasing the stability of the tooling. When processing workpieces with relatively smooth surfaces, the tooling can further enhance the stability of the relative position between the tooling and the workpiece through the reinforcement mechanism. This reduces the possibility of momentary slippage of the hole punch during use, solving the problem that some hardware tools are prone to slippage during drilling operations, resulting in poor safety and potential damage to the workpiece surface.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 As shown, a fixing fixture for drilling holes in hardware tools includes an electric drill body 1 and a hole opener body 2 installed at one end of the output shaft of the electric drill body 1. A fixing ring 3 is fixedly sleeved on the surface of the electric drill body 1, and a collar 4 is fixedly sleeved on the surface of the fixing ring 3. A movable plate 5 slides through the surface of the collar 4. A connecting ring 6 is fixedly connected to one side of the movable plate 5, and the surface of the connecting ring 6 contacts the surface of the collar 4. The setting of the connecting ring 6 facilitates the simultaneous movement of multiple movable plates 5, reducing problems such as uneven force on the anti-slip ring 7 when a single movable plate 5 moves. An anti-slip ring 7 is fixedly connected to the other side of the movable plate 5. When the anti-slip ring 7 contacts a workpiece with a rough surface, it can provide a grip on the fixture. Position restriction is designed to reduce the possibility of the tool being tilted, thereby reducing the problem of slippage. The surface of the collar 4 is equipped with a reset mechanism 8. Grooves are provided on both sides of the anti-slip ring 7. The inner wall of the groove is fixedly connected to a U-shaped plate 9. The inner wall of the U-shaped plate 9 is rotatably connected to a rotating frame 10. The top and bottom of the rotating frame 10 are fixedly connected to a rotating shaft, which rotates through the U-shaped plate 9. A reinforcing mechanism 12 is provided inside the rotating frame 10. The surface of the rotating frame 10 is provided with a slot 11. When the operator uses this tool to process workpieces with relatively smooth and regular surfaces such as ceramic tiles, the reinforcing mechanism 12 cooperates with the workpiece to restrict the position of the electric drill body 1 and the hole opener body 2.

[0023] The reset mechanism 8 includes a support plate 81, a reset plate 82, a guide rod 83, and a compression spring 84. The support plate 81 is fixedly connected to the surface of the collar 4. The guide rod 83 slides through the support plate 81. The reset plate 82 is fixedly connected to the surface of the moving plate 5. One end of the guide rod 83 is fixedly connected to the surface of the reset plate 82. The compression spring 84 is sleeved on the surface of the guide rod 83. When the operator pushes the drill body 1, the surface of the hole opener body 2 contacts the surface of the workpiece and performs drilling. During this process, the moving plate 5 moves in the direction of the drill body 1. The anti-slip ring 7 is pressed tightly against the surface of the workpiece. The reset plate 82 moves with the moving plate 5. The guide rod 83 guides the movement of the reset plate 82 and the moving plate 5. At this time, the compression spring 84 is shortened by force. Then, under the action of the elastic force of the compression spring 84, the reset plate 82 drives the moving plate 5 to reset for subsequent use.

[0024] The reinforcement mechanism 12 includes an extension plate 121, a bolt 122, a threaded sleeve 123, and a reinforcement plate 124. The surface of the extension plate 121 is slidably connected to the inner wall of the rotating frame 10. The bolt 122 is fixedly connected to the surface of the extension plate 121 and contacts the inner wall of the slot 11. The threaded sleeve 123 is threaded onto the surface of the extension plate 121 and contacts the surface of the rotating frame 10. The reinforcement plate 124 is fixedly connected to the surface of the extension plate 121. The operator can adjust the position of the extension plate 121 according to the length of the workpiece. After that, the operator can fix the position of the extension plate 121 by the cooperation of the bolt 122 and the threaded sleeve 123. The operator places the reinforcement plates 124 on the surfaces of the two sides of the workpiece and fixes the position of the extension plate 121. At this time, the reinforcement plate 124 clamps the workpiece, the movement of the reinforcement mechanism 12 is restricted, and the stability of the electric drill body 1 and the hole opener body 2 during use is reinforced.

[0025] Limiting blocks 13 are fixedly connected to the top and bottom of the extension plate 121. Limiting grooves 14 are opened at the top and bottom of the inner wall of the rotating frame 10. The surface of the limiting block 13 is slidably connected to the inner wall of the limiting groove 14. The position of the extension plate 121 can be limited and guided by the cooperation of the limiting block 13 and the limiting groove 14, thereby increasing the stability of the extension plate 121 when it moves.

[0026] The cross-section of the reinforcing plate 124 is trapezoidal, and one side of the surface of the reinforcing plate 124 is inclined, which makes it easy for the reinforcing plate 124 to be used for workpieces with small gaps on both sides.

[0027] Working principle: When drilling holes in a workpiece with a relatively rough surface, the operator can hold the electric drill body 1 and place the anti-slip ring 7 against the surface of the workpiece. The contact between the anti-slip ring 7 and the surface of the workpiece can limit the position and angle of this tooling. The operator starts the electric drill body 1 and pushes the electric drill body 1 towards the surface of the workpiece. The surface of the anti-slip ring 7 is in close contact with the surface of the workpiece, and the surface of the hole opener body 2 is in contact with the surface of the workpiece. At this time, the hole opener body 2, which rotates with the output shaft of the electric drill body 1, can drill holes in the surface of the workpiece.

[0028] When drilling holes in workpieces with relatively smooth surfaces and regular shapes, the operator can first rotate the rotating frame 10 and adjust the rotating frame 10 to... Figure 3 As shown, the operator then adjusts the position of the extension plate 121 according to the length of the workpiece so that the reinforcing plates 124 on both sides can contact the surfaces of the workpiece on both sides respectively. The operator rotates the screw sleeve 123, and the screw sleeve 123 moves to the position of the rotating frame 10, thereby fixing the position of the extension plate 121. In this way, the relative position between the electric drill body 1 and the workpiece can be restricted by the reinforcing mechanism 12. The operator starts the electric drill body 1 and pushes the electric drill body 1 to the position of the workpiece. The surface of the anti-slip ring 7 is in close contact with the surface of the workpiece, and the hole opener body 2 can perform stable drilling operations.
