Description

Technical Field

[0001] This utility model belongs to the field of wrenches, specifically a magnetic anti-loss drill chuck wrench. Background Technology

[0002] Drill chucks are a key component of equipment such as electric drills or manual drill presses, used to firmly clamp various types of drill bits. They usually have wrench holes, and the drill chuck wrench, as a special tool, is mainly used to connect to the wrench hole and operate the drill chuck, thereby achieving the clamping or loosening of the drill bit.

[0003] Existing drill chuck wrenches mainly consist of a handle, a wrench bar, and a wrench wheel. When operating the drill chuck, one end of the wrench bar is inserted into the wrench hole, causing it to drive the wrench wheel to engage with the teeth on the outside of the drill chuck. Then, by turning the handle, the handle drives the wrench wheel and the wrench bar to rotate, thereby causing the wrench wheel to engage with the teeth and clamp or loosen the drill rod on the drill chuck.

[0004] However, most existing drill chuck wrenches and drill chucks are separate units, requiring the wrench to be assembled only when changing drill bits. Furthermore, the wrench is relatively small, which makes it easy for it to be lost when not in use.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a magnetic anti-loss drill chuck wrench. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a magnetic anti-loss drill chuck wrench, which solves the problem that the wrench and drill chuck are separated in the prior art, making it easy to lose when not in use.

[0007] A magnetic anti-loss drill chuck wrench includes a handle, a lever on one side of the handle, a mounting groove at one end of the lever, a powerful magnet rotatably connected to the mounting groove via a bearing, the powerful magnet being magnetically connected to the wrench hole of the drill chuck to be installed, the lever having a hollow internal structure, a sliding post slidably connected to its inner side, a positioning pin assembly at one end of the sliding post, and two ends of the outer side of the sliding post connected to a wheel and a connecting ring, both of which are located on the outer side of the lever.

[0008] Preferably, a connecting block passing through the lever is provided between the lever and the connecting ring and the moving column, and through slots are provided on both sides of the lever for the connecting block to move.

[0009] Preferably, the locking pin assembly includes a locking plate, ear blocks, retaining springs, and a synchronizing element. Two sets of limiting frames are symmetrically arranged at one end of the moving column. Ear blocks are slidably connected to both sets of limiting frames. A locking plate is connected to the opposite side of each of the two ear blocks. A synchronizing element is arranged between the two locking plates. A retaining spring abuts against the opposite ends of each of the two ear blocks. The retaining spring is sleeved on the limiting frame.

[0010] Preferably, the card plate includes a first vertical section, a second vertical section, and a horizontal section. The opposite ends of the first vertical section and the second vertical section are respectively connected to the two ends of the horizontal section, and the two lugs are respectively connected to the opposite sides of the two second vertical sections.

[0011] Preferably, the top and bottom of the lever are symmetrically provided with two sets of insertion holes, and the locking plate passes through the corresponding insertion holes via two first vertical sections and engages with the lever.

[0012] Preferably, the synchronizing element includes a gear and a toothed rack. One end of the moving column is rotatably connected to the gear, and the two sets of second vertical sections are provided with toothed racks on opposite sides. The two sets of toothed racks are respectively meshed with the two sides of the gear.

[0013] Compared with the prior art, this utility model has the following advantages: A strong magnet is provided at the end of the wrench handle, which magnetically connects the entire wrench to the drill chuck. When not in use, it does not require manual installation on the drill chuck, making the connection convenient and less likely to be lost. At the same time, it improves operating efficiency in scenarios where drill bits need to be changed frequently. The wrench wheel is movably mounted on the wrench handle through a moving column and a locking pin assembly. Utilizing the cooperation of a locking plate, lug, snap ring, and synchronizing component, the locking plate engages with the insertion holes at different positions, thereby adjusting the position of the wrench wheel. When in use, the wrench wheel can be adjusted to engage with the teeth on the drill chuck. When not in use, it can be adjusted to detach freely from the drill chuck, thus misaligning with the teeth on the drill chuck and preventing accidental contact with the handle when not in use from affecting the operation of the drill chuck.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] As attached Figure 1 To be continued Figure 5 As shown:

[0023] This utility model provides a magnetic anti-loss drill chuck wrench, including a handle 1, a lever 2 on one side of the handle 1, an installation groove 3 at one end of the lever 2, a powerful magnet 4 rotatably connected to the installation groove 3 via a bearing, the powerful magnet 4 being magnetically connected to the wrench hole of the drill chuck to be installed, the lever 2 having a hollow internal structure, a movable column 5 slidably connected to its inner side, a positioning pin assembly 6 at one end of the movable column 5, and two ends of the outer side of the movable column 5 being connected to a lever 7 and a connecting ring 8, both of which are located on the outer side of the lever 2.

[0024] refer to Figure 2 and Figure 3 A connecting block 9 is provided between the lever 7 and the connecting ring 8 and the moving column 5, passing through the lever 2. Through slots 10 are provided on both sides of the lever 2 for the connecting block 9 to move.

[0025] The through groove 10 can limit the movement trajectory of the connecting block 9, so that when the lever 2 is turned by the handle 1, the moving column 5 and the lever 7 can be driven to rotate synchronously.

[0026] refer to Figure 4 The locking pin assembly 6 includes a locking plate 601, an ear block 602, a retaining spring 603, and a synchronizing element 604. Two sets of limiting frames 11 are symmetrically arranged at one end of the moving column 5. An ear block 602 is slidably connected to each of the two sets of limiting frames 11. A locking plate 601 is connected to the opposite side of each of the two ear blocks 602. A synchronizing element 604 is arranged between the two locking plates 601. A retaining spring 603 is abutted at the opposite ends of each of the two ear blocks 602. The retaining spring 603 is sleeved on the limiting frame 11.

[0027] refer to Figure 5The card plate 601 includes a first vertical section 6011, a second vertical section 6012 and a horizontal section 6013. The opposite ends of the first vertical section 6011 and the second vertical section 6012 are respectively connected to the two ends of the horizontal section 6013. The two ear blocks 602 are respectively connected to the opposite sides of the two second vertical sections 6012.

[0028] refer to Figure 1 and Figure 2 The top and bottom of the lever 2 are symmetrically provided with two sets of insertion holes 12. The locking plate 601 passes through the corresponding insertion holes 12 via two first vertical sections 6011 and engages with the lever 2.

[0029] In this process, the snap ring 603 applies an elastic force to the lug 602, so that when there is no external force, the snap ring 603 drives one end of the snap plate 601 through the lug 602 to engage with the lever 2, thereby limiting the movement of the column 5.

[0030] refer to Figure 5 The synchronizing element 604 includes a gear 6041 and a toothed rack 6042. One end of the moving column 5 is rotatably connected to the gear 6041. The two sets of second vertical sections 6012 are provided with toothed racks 6042 on opposite sides. The two sets of toothed racks 6042 are respectively meshed with the two sides of the gear 6041.

[0031] When one side of the card plate 601 moves vertically along the guide frame, it drives the gear 6041 to rotate through the toothed 6042 on the side of the second vertical section 6012. During the rotation of the gear 6041, it will act on the toothed 6042 on the second vertical section 6012 of the other card plate 601, so that the two card plates 601 can produce synchronous reverse displacement.

[0032] Working principle: One end of the lever 2 is tightly attracted to the wrench hole of the drill chuck by a strong magnet 4. At the same time, the wrench wheel 7 on the lever 2 is engaged with the teeth on the drill chuck. By rotating the handle 1, the handle 1 drives the wrench wheel 7 to rotate through the lever 2. Since the strong magnet 4 and the lever 2 are rotatably connected, the rotation of the lever 2 will not affect the stability of the connection between the strong magnet 4 and the drill chuck. The rotation of the wrench wheel 7 drives the internal clamping plate of the drill chuck to move, clamping or loosening the drill rod on the drill chuck. After adjustment, the clamping plate 601 is pressed, causing the first vertical section 6011 on the clamping plate 601 to move into the wrench lever under the pressure. On the side, under the action of the synchronizing element 604, the first vertical sections 6011 of the two clamping plates 601 will move synchronously. At this time, the positioning effect on the moving column 5 is released. Then, the connecting ring 8 is manually slid, so that the connecting ring 8 drives the wrench 7 to move outside the lever 2 through the moving column 5 until the first vertical section 6011 is aligned with the outer insertion hole 12. This repositions the moving column 5 and the wrench 7. In this position, the wrench 7 and the teeth on the drill chuck are misaligned, which avoids the drill chuck from loosening the drill rod due to accidental operation of the handle 1 when not in use. This ensures the stability of the drill chuck's operation. Moreover, due to the setting of the strong magnet 4, it is not easy to lose when not in use.
