Detailed Implementation

[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] Example 1: Please refer to again Figure 1-5This utility model provides a plastic brush that can be connected to an electric drill, including a mounting plate 100. A brush plate 110 is slidably connected to the bottom of the mounting plate 100. Mounting grooves 120 are opened on both sides of the interior of the mounting plate 100. A latch 130 is slidably connected to the inner cavity of the mounting groove 120. One end of the latch 130 passes through the mounting groove 120 and extends into the interior of the brush plate 110. The other end of the latch 130 is fixedly connected to a mounting rod 140. A compression spring 141 is sleeved on the outer wall of the mounting rod 140. One end of the mounting rod 140... A mounting rod 140 extends through the mounting groove 120 and to the outside of the mounting plate 100. One end of the mounting rod 140 is fixedly connected to a connecting plate 150. A pull rod 160 is rotatably connected to one side of the connecting plate 150. One end of the pull rod 160 extends through the connecting plate 150 and to one side of the connecting plate 150. A locking bolt 161 is fixedly connected to one end of the pull rod 160. The locking bolt 161 is screwed to the mounting plate 100. A tapered connecting post 170 is fixedly connected to the top of the mounting plate 100. The tapered connecting post 170 is inserted into the connecting seat 200.

[0023] Specifically, when replacing the worn brush plate 110, the locking bolt 161 on the pull rod 160 is rotated to remove the screw connection with the mounting plate 100. Then, the pull rod 160 is pulled outward to move the connecting plate 150, which in turn moves the mounting rod 140. The latch 130 on the mounting rod 140 presses against the compression spring 141 and moves into the mounting groove 120, thus removing the fixation of the brush plate 110. The brush plate 110 can then be slid out of the mounting plate 100. The new brush plate 110 is then slidably installed into the mounting plate 100. The pull rod 160 is then released, causing the compression spring 141, which was pressed by the latch 130, to return to its original position and extend, pushing the latch 130 to move and insert it into the replaced brush plate 110, thus fixing the brush plate 110 in place.

[0024] Example 2: Please refer to again Figure 1-5 A connecting seat 200 is provided above the mounting plate 100. The connecting seat 200 has limit grooves 210 on both sides inside. A sliding plate 220 is slidably connected to the inner cavity of the limit groove 210. An arc-shaped tenon 221 is fixedly connected to one side of the sliding plate 220. One end of the arc-shaped tenon 221 passes through the limit groove 210 and extends into the inner cavity of the conical connecting pile 170. Threaded connecting rods 230 are screwed to both sides of the outer side of the connecting seat 200. One end of the threaded connecting rod 230 passes through the connecting seat 200 and extends into the inner cavity of the limit groove 210. One end of the threaded connecting rod 230 is rotatably connected to the sliding plate 220. A return spring 240 is sleeved on the outer wall of the threaded connecting rod 230. A connecting sleeve 250 is fixedly connected to the top of the connecting seat 200.

[0025] Specifically, when connecting the plastic brush to the electric drill, the tapered connecting pin 170 on the top of the mounting plate 100 is inserted into the connecting seat 200. This causes the tapered connecting pin 170 to press against the two arc-shaped tenons 221 on either side of the connecting seat 200. After the tapered connecting pin 170 presses against the arc-shaped tenons 221, the arc-shaped tenons 221 automatically press against the return spring 240 and retract into the limiting slide groove 210. Then, when the tapered connecting pin 170 is fully inserted, the arc-shaped tenons 221 coincide with the positioning hole on the tapered connecting pin 170, at which point the slide groove... The return spring 240, pressed by plate 220, resets and pushes the slide plate 220 to move, so that the arc is inserted into the conical connecting post 170. Then, the threaded connecting rod 230 is rotated to connect the threaded connecting rod 230 with the connecting seat 200, completing the connection between the mounting plate 100 and the connecting seat 200. Then, the drill connecting rod 251, which is screwed into the inner side of the connecting sleeve 250 at the top of the connecting seat 200, is connected to the power output shaft of the drill, so that the plastic brush can be connected and used with the drill. Alternatively, the drill connecting rod 251 can be removed from the connecting seat 200 to use the plastic brush manually.

[0026] Working principle: When replacing the worn brush plate 110, the locking bolt 161 on the pull rod 160 is rotated by rotating the pull rod 160 to remove the screw connection with the mounting plate 100. Then, the pull rod 160 is pulled outward to move the connecting plate 150, which in turn moves the mounting rod 140. The latch 130 on the mounting rod 140 presses the compression spring 141 and moves it into the mounting groove 120, thus removing the fixation of the brush plate 110. The brush plate 110 can then be slid out of the mounting plate 100. The new brush plate 110 is then slidably installed into the mounting plate 100. The pull rod 160 is then released, causing the compression spring 141, which was pressed by the latch 130, to reset and extend, pushing the latch 130 to move and insert it into the replaced brush plate 110, thus fixing the brush plate 110.

[0027] When connecting the plastic brush to the electric drill, the tapered connecting post 170 on the top of the mounting plate 100 is inserted into the connecting seat 200. This causes the tapered connecting post 170 to press against the two arc-shaped tenons 221 on either side of the connecting seat 200. After the tapered connecting post 170 presses against the arc-shaped tenons 221, the arc-shaped tenons 221 automatically press against the return spring 240 and retract into the limiting groove 210. Then, when the tapered connecting post 170 is fully inserted, the arc-shaped tenons 221 coincide with the positioning hole on the tapered connecting post 170, at which point they are squeezed by the sliding plate 220. The pressure-reset spring 240 resets and pushes the slide plate 220 to move, so that the arc is inserted into the tapered connecting post 170. Then, the threaded connecting rod 230 is rotated to connect the threaded connecting rod 230 to the connecting seat 200, completing the connection between the mounting plate 100 and the connecting seat 200. Then, the drill connecting rod 251 screwed into the inner side of the connecting sleeve 250 at the top of the connecting seat 200 is connected to the power output shaft of the drill, so that the plastic brush can be connected and used with the drill. Alternatively, the drill connecting rod 251 can be removed from the connecting seat 200 and the plastic brush can be used manually.
