Description

Technical Field

[0001] This utility model relates to the field of electric drill drilling technology, and in particular to an angle-adjustable handheld electric drill holder. Background Technology

[0002] An adjustable handheld drill stand is an auxiliary tool designed specifically for handheld drills. It allows for flexible adjustment of the drill's working angle and provides stable support. Through a mechanical structure, it enables the adjustment and fixation of the drill's angle, while replacing the direct gripping and force application of the hand, thus improving the stability, accuracy, and safety of drilling operations.

[0003] A search revealed Chinese Patent Publication No. CN217142425U, which discloses a handheld electric drill drilling stabilizing bracket. The technical solution includes a bracket with an auxiliary stabilizing mechanism on its exterior and a handheld electric drill assembly on the exterior. The auxiliary stabilizing mechanism includes an adjustment box fitted over the bracket, with a cavity inside. Grooves are formed on both sides of the cavity's inner side, and a drive shaft is located inside the cavity. The beneficial effects of the handheld electric drill drilling stabilizing bracket are: by contacting the anti-slip pad in the auxiliary stabilizing mechanism with the workpiece surface, the handheld electric drill body is kept perpendicular to the workpiece surface, preventing drill bit breakage due to drilling tilt or workpiece scrap due to quality issues, thus reducing quality problems and economic losses. The adjustment box can slide along the bracket by disengaging the movable teeth from the rack. The height of the adjustment box determines the drilling depth; when the adjustment plate contacts the adjustment box, the handheld electric drill body no longer descends. However, when manually adjusting the clamp, the angle is adjusted using bolts or clips, requiring tools, making the operation cumbersome and difficult to guarantee accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an angle-adjustable handheld drill holder, which aims to improve the problem that in the prior art, when manually adjusting the clamp, the angle is adjusted by bolts or buckles, which requires tools to assist in the adjustment, and the operation is cumbersome and it is difficult to guarantee the accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an angle-adjustable handheld electric drill bracket, including a base, connecting blocks fixedly connected to the left and right sides of the top wall of the base, a support arm rotatably connected to the outer wall of the connecting blocks, an adjustment mechanism provided on the outer wall of the base for precisely adjusting the angle of the connecting blocks, and a clamping mechanism provided on the inner side of the support arm for fixing the electric drill. The adjustment mechanism includes an arc-shaped slide rail, which is fixedly connected to the right side of the outer wall of the base. A scale is installed on the right side of the outer wall of the arc-shaped slide rail. A slider is fixedly connected to the right side of the outer wall of the support arm. The slider is slidably connected to the arc-shaped slide rail. A locking component is provided on the outer wall of the base.

[0006] With the above technical solution: the support arm rotates within the connecting block on the base, and at the same time, the support arm drives the slider to slide within the arc-shaped slide rail on the right side of the base. The required angle can be accurately determined through the scale on the right side of the arc-shaped slide rail.

[0007] As a further description of the above technical solution: The locking assembly includes a knob, which is located on the right side of the outer wall of the slider. A bevel gear is fixedly connected to the left side of the outer wall of the knob. A bevel gear is installed at the bottom of the bevel gear. The bottom left side of the outer wall of the bevel gear is meshed with the top right side of the outer wall of the bevel gear. A lead screw is fixedly connected to the bottom of the outer wall of the bevel gear. The lead screw is rotatably connected to the inner wall of a square groove. A square groove is formed on the bottom wall of the slider. A friction plate is slidably connected to the inner wall of the square groove. A threaded groove is formed on the top wall of the friction plate. The threaded groove is threadedly connected to the lead screw.

[0008] Through the above technical solution: Knob 1 drives the lead screw to rotate through bevel gear 1 and bevel gear 2. The lead screw rotates in the threaded groove of the friction plate, causing the friction plate to slide in the square groove. Under the action of the lead screw, the friction plate moves and presses against the arc-shaped slide rail.

[0009] As a further description of the above technical solution: The clamping mechanism includes a hollow block, which is fixedly connected to the end of the support arm. Clamping blocks are provided on both the left and right sides inside the hollow block. A second slider is fixedly connected to the rear side of the outer wall of the clamping block. A sliding groove is opened on the rear side of the inner wall of the hollow block. The second slider is slidably connected to the sliding groove. A driving component is provided on the outer wall of the support arm.

[0010] Through the above technical solution: the slider 2 on the clamping block slides in the groove, and the clamping block can fit against the electric drill body, thereby achieving a stable clamping or loosening of the electric drill.

[0011] As a further description of the above technical solution: The drive assembly includes a second knob, which is located on the front right side of the outer wall of the hollow block. A bidirectional threaded rod is fixedly connected to the left side of the outer wall of the second knob, and the bidirectional threaded rod is threadedly connected to the clamping block.

[0012] Through the above technical solution: Knob 2 drives the bidirectional threaded rod to rotate inside the hollow block, and the bidirectional threaded rod drives the two clamping blocks to move closer or further away synchronously.

[0013] As a further description of the above technical solution: The bevel gear is rotatably connected inside the slider, and the friction plate is disposed on the inner side of the arc-shaped slide rail.

[0014] Through the above technical solution: the bevel gear can flexibly adapt to the angle change generated when the slider slides along the arc-shaped slide rail. When the friction plate moves downward under the drive of the lead screw, it directly and tightly contacts the arc-shaped slide rail, and firmly locks the slider on the arc-shaped slide rail through friction.

[0015] As a further description of the above technical solution: The bidirectional threaded rod is rotatably connected inside the hollow block, and the clamping block adopts an arc-shaped design.

[0016] Through the above technical solution: the hollow block provides space for the rotation of the bidirectional threaded rod, ensuring that it will not deviate or shake when rotated under force, and the arc-shaped clamping block can fit the body of the electric drill.

[0017] As a further description of the above technical solution: The outer wall of the support arm is provided with a rubber pad, which is fixedly connected to the outer wall of the clamping block.

[0018] The above technical solution uses rubber pads to enhance the fit and tightness between the clamping block and the electric drill, preventing the electric drill from shifting or slipping due to vibration during drilling operations, and improving clamping stability.

[0019] As a further description of the above technical solution: The base has a convex design, and mounting holes are provided at the four corners of the top wall of the base.

[0020] The above technical solution involves a convex design for the base that lowers the center of gravity and reduces unnecessary space occupation at the top. Bolts are inserted into the mounting holes to securely lock the base to the workbench.

[0021] This utility model has the following beneficial effects: 1. In this utility model, when adjusting the angle, loosen knob one and rotate the support arm so that it rotates within the connecting block on the base 1. At the same time, the support arm drives slider one to slide within the arc-shaped slide rail on the right side of the base. The required angle is accurately determined by the scale on the right side of the arc-shaped slide rail. After the angle is adjusted, tighten knob one. Knob one drives the lead screw to rotate within the threaded groove of the friction plate through the meshing of bevel gear one and bevel gear two. This causes the friction plate to slide within the square groove. The friction plate moves under the action of the lead screw and presses against the arc-shaped slide rail, fixing the position of the support arm and achieving precise angle drilling.

[0022] 2. In this utility model, when fixing the electric drill, turn the second knob to drive the bidirectional threaded rod to rotate inside the hollow block, and the second slider on the clamping block slides in the groove, so that the bidirectional threaded rod drives the two clamping blocks to move closer or further away synchronously. Because the clamping blocks are arc-shaped, they can fit the electric drill body, thereby achieving a stable clamping or loosening of the electric drill. Attached Figure Description

A bevel gear 4042 is fixedly connected to the left side of the outer wall of the knob 4041. A bevel gear 4047 is installed at the bottom of the bevel gear 4042. The bottom left side of the outer wall of the bevel gear 4042 meshes with the top right side of the outer wall of the bevel gear 4047. A lead screw 4043 is fixedly connected to the bottom of the outer wall of the bevel gear 4047. The lead screw 4043 is rotatably connected to the inner wall of the square groove 4044. The bottom wall of the slider 403 has a square groove 4044. A friction plate 4045 is slidably connected to the inner wall of the square groove 4044. A threaded groove 4046 is opened on the top wall of the friction plate 4045. The threaded groove 4046 is threadedly connected to the lead screw 4043. Specifically, the electric drill is fixed in place by the clamping mechanism 5 on the support arm 3. When adjusting the angle, loosen knob 4041 and rotate the support arm 3. The support arm 3 rotates within the connecting block 2 on the base 1. Simultaneously, the support arm 3 drives slider 403 to slide within the arc-shaped slide rail 401 on the right side of the base 1. The required angle can be precisely determined using the dial 402 on the right side of the arc-shaped slide rail 401. After the angle adjustment is complete, tighten knob 4041. Knob 4041 drives the lead screw 4043 to rotate via bevel gear 4042. The lead screw 4043 rotates within the threaded groove 4046 of the friction plate 4045, causing the friction plate 4045 to slide within the square groove 4044. Under the action of the lead screw 4043, the friction plate 4045 moves and presses against the arc-shaped slide rail 401, thereby fixing the position of the support arm 3 and enabling precise angle drilling.

[0027] Reference Figure 2 and Figure 5 The clamping mechanism 5 includes a hollow block 501, which is fixedly connected to the end of the support arm 3. Clamping blocks 502 are provided on both the left and right sides inside the hollow block 501. A second slider 503 is fixedly connected to the rear side of the outer wall of the clamping block 502.

The bidirectional threaded rod 5052 is threadedly connected to the clamping block 502. The bidirectional threaded rod 5052 is rotatably connected inside the hollow block 501. The clamping block 502 adopts an arc-shaped design. Specifically, when it is necessary to fix the electric drill, rotate knob 2 5051. Knob 2 5051 drives the bidirectional threaded rod 5052 to rotate inside the hollow block 501. The slider 2 503 on the clamping block 502 slides in the groove 504, causing the bidirectional threaded rod 5052 to drive the two clamping blocks 502 to move closer or further apart synchronously. The clamping blocks 502 with arc design can fit against the electric drill body, thereby achieving a stable clamping or release of the electric drill.

[0028] Reference Figure 1 and Figure 2 The outer wall of the support arm 3 is provided with a rubber pad 6, which is fixedly connected to the outer wall of the clamping block 502. The base 1 adopts a convex design, and mounting holes 7 are provided at the four corners of the top wall of the base 1. Specifically, the rubber pad 6 is used to enhance the fit and tightness between the clamping block 502 and the electric drill, prevent the electric drill from shifting or slipping due to vibration during drilling operations, and improve clamping stability. The convex design of the base 1 can lower the center of gravity of the base 1 and reduce unnecessary space occupation at the top. The base 1 is firmly locked to the worktable by inserting bolts into the mounting hole 7.

[0029] Working principle: The electric drill is fixed by the clamping mechanism 5 on the support arm 3. When adjusting the angle, loosen the knob 4041 and rotate the support arm 3. The support arm 3 rotates in the connecting block 2 on the base 1. At the same time, the support arm 3 drives the slider 403 to slide in the arc-shaped slide rail 401 on the right side of the base 1. The required angle can be accurately determined by the scale 402 on the right side of the arc-shaped slide rail 401. After the angle is adjusted, tighten the knob 4041. The knob 4041 can drive the lead screw 4043 to rotate through the meshing of the bevel gear 4042 and the bevel gear 4047. The lead screw 4043 rotates in the thread groove 4046 of the friction plate 4045, so that the friction plate 4045 slides in the square groove 4044. Under the action of the lead screw 4043, the friction plate 4045 moves and presses against the arc-shaped slide rail 401, fixing the position of the support arm 3, which can perform precise angle drilling. When it is necessary to fix the electric drill, turn knob 2 5051. Knob 2 5051 drives the bidirectional threaded rod 5052 to rotate inside the hollow block 501. The slider 2 503 on the clamping block 502 slides in the groove 504, so that the bidirectional threaded rod 5052 drives the two clamping blocks 502 to move closer or further away at the same time. The arc-shaped clamping block 502 can fit against the electric drill body, thereby achieving a stable clamping or loosening of the electric drill.
