Description

Technical Field

[0001] This utility model relates to the technical field of drill chuck locking devices, and in particular to an improved drill chuck wrench. Background Technology

[0002] Drill chucks are one of the main accessories in the power tool and machine tool industries, and are widely used in electric drills and drilling machines. Currently, the common drill chuck wrench has a T-shaped structure, including a positioning head, toothed jaws, and a force-applying rod. When performing the actions of loosening and tightening the drill chuck, first insert the positioning head of the drill chuck wrench into the positioning hole on the drill chuck, and then hold the force-applying rod of the drill chuck wrench and press down while turning it to loosen or tighten the drill chuck.

[0003] Most existing drill chucks are cast in one piece. During use, different drill models require different sizes of drill chuck wrenches. When multiple drills or drilling machines need to be repaired or disassembled, multiple drill chuck wrenches of different sizes need to be prepared, which increases the workload of the workers. Moreover, after long-term use, the teeth of the fastening head on the surface of the drill chuck wrench will be worn. When it needs to be replaced, the entire drill chuck must be replaced, which is not conducive to the conservation of resources. Therefore, this utility model provides an improved drill chuck wrench. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, the present invention provides an improved drill chuck wrench.

[0015] (III) Beneficial Effects

[0016] This utility model provides an improved drill chuck wrench. It has the following beneficial effects:

[0017] 1. By turning the knob, the lead screw can be rotated. When the lead screw rotates, the moving ring on the surface of the lead screw moves on the surface of the lead screw by means of the thread. The movement of the moving ring can drive the X-shaped movable frame to rotate. The rotation of the X-shaped movable frame can push the limit block to move, thereby achieving the effect of quick installation and replacement of the drill bit.

[0018] 2. By pushing the positioning block into the pre-drill chuck, the positioning block will simultaneously compress the return spring through the slide rod and push plate, causing the return spring to undergo elastic deformation. After the positioning block is inserted into the drill chuck, the drill bit and the surface of the drill chuck mesh with each other. Then, by rotating the handle, the drill bit is rotated, thereby disassembling the drill chuck. After disassembly, the operator no longer presses on the positioning block, allowing the return spring to push the positioning block out of the pre-drill chuck through the reaction force generated by the recovery elastic deformation, thus preventing the positioning block from getting stuck in the pre-drill chuck.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides an improved drill chuck wrench, including a handle 1, a sliding tube 2 fixedly connected to the top of the handle 1, an extension rod 3 slidably connected to the inner wall of the sliding tube 2, and an installation component 5 provided on the top of the extension rod 3.

[0029] The mounting assembly 5 includes a mounting cylinder 501, which is fixedly connected to the surface of the extension rod 3. A lead screw 502 is rotatably connected inside the mounting cylinder 501. A fixed ring 503 and a movable ring 504 are sleeved on one end of the lead screw 502. The inner wall of the movable ring 504 is threadedly connected to the surface of the lead screw 502. One side of the fixed ring 503 is fixedly connected to the surface of the mounting cylinder 501. A rotating seat 505 is fixedly connected to the surface of both the fixed ring 503 and the movable ring 504. An X-shaped movable frame 506 is rotatably connected to the surface of the rotating seat 505. A limit block 507 is fixedly connected to one side of the movable frame.

[0030] Specifically, an adjusting bolt 4 is provided at the connection between the sliding tube 2 and the extension rod 3. The adjusting bolt 4 is threadedly connected to the surface of the sliding tube 2. A knob 508 is provided at the end of the lead screw 502 away from the limiting block 507. One side of the knob 508 is fixedly connected to the surface of the lead screw 502. The number of limiting blocks 507 is set to four, and the surface of each of the four limiting blocks 507 is provided with anti-slip texture 509.

[0031] Furthermore, rotating the knob 508 can drive the lead screw 502 to rotate. When the lead screw 502 rotates, the moving ring 504 on the surface of the lead screw 502 moves on the surface of the lead screw 502 by means of the thread. The movement of the moving ring 504 can drive the X-shaped movable frame 506 to rotate. The rotation of the X-shaped movable frame 506 pushes the limit block 507 to move, thereby achieving the effect of quick installation and replacement of the drill bit 604.

[0032] Example 2

[0033] Reference Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. A wrench assembly 6 is provided on one side of the mounting cylinder 501. The wrench assembly 6 includes a fixing seat 601. The fixing seat 601 is sleeved on the surface of the limiting block 507. A fixing cylinder 603 is fixedly connected to one side of the fixing seat 601. A tightening drill bit 604 is fixedly connected to one end of the fixing cylinder 603. A sliding groove 605 is opened on the surface of the tightening drill bit 604. A sliding rod 607 is slidably connected to the inner wall of the sliding groove 605. A positioning block 606 is fixedly connected to one end of the sliding rod 607.

[0034] Specifically, a limiting groove 602 is provided on the inner wall of the fixed base 601. The inner wall of the limiting groove 602 is pressed against the surface of the limiting block 507. A push plate 608 is fixedly connected to the end of the slide rod 607 away from the positioning block 606. A return spring 609 is provided on one side of the push plate 608. One end of the return spring 609 is fixedly connected to the inner wall of the fixed cylinder 603.

[0035] Furthermore, when it is necessary to disassemble or tighten the drill chuck, the positioning block 606 can be pushed into the reserved slot of the drill chuck. At the same time, the positioning block 606 will squeeze the return spring 609 through the slide rod 607 and the push plate 608, causing the return spring 609 to undergo elastic deformation. After the positioning block 606 is inserted into the drill chuck, the drill bit 604 engages with the surface of the drill chuck. Then, by rotating the handle 1, the drill bit 604 is rotated, thereby disassembling the drill chuck. After disassembly, the operator no longer presses on the positioning block 606, so that the return spring 609 pushes the positioning block 606 out of the reserved slot through the reaction force generated by the recovery elastic deformation, preventing the positioning block 606 from getting stuck in the reserved slot.

[0036] Working principle: When it is necessary to disassemble or tighten the drill chuck, the positioning block 606 can be pushed into the reserved slot of the drill chuck. At the same time, the positioning block 606 will compress the return spring 609 through the slide rod 607 and the push plate 608, causing the return spring 609 to elastically deform. After the positioning block 606 is inserted into the drill chuck, the drill bit 604 engages with the surface of the drill chuck. Then, by rotating the handle 1, the drill bit 604 is rotated, thereby disassembling the drill chuck. After disassembly, the operator no longer presses on the positioning block 606, allowing the return spring 609 to return to its original position. The reaction force generated by the complex elastic deformation pushes the positioning block 606 out of the reserved slot, preventing the positioning block 606 from getting stuck in the reserved slot. When the tightening drill bit 604 wears out and needs to be replaced, the knob 508 can be turned to drive the lead screw 502 to rotate. When the lead screw 502 rotates, the moving ring 504 on the surface of the lead screw 502 moves on the surface of the lead screw 502 by means of the thread. The movement of the moving ring 504 can drive the X-shaped movable frame 506 to rotate. The rotation of the X-shaped movable frame 506 pushes the limit block 507 to move, thereby achieving the effect of quick installation and replacement of the tightening drill bit 604.
