Description

Technical Field

[0001] This utility model relates to the field of manual hardware tools, and in particular to an adjustable wrench with horizontal rotation adjustment. Background Technology

[0002] Currently, hexagonal nuts, as commonly used standard fasteners, are widely used in the machinery and construction industries, driving the consumer market for related disassembly tools. Adjustable wrenches, due to their built-in adjustment function, can handle various sizes of hexagonal nuts, making them more popular with consumers compared to ordinary hexagonal wrenches. However, all current adjustable wrenches have vertically rotating worm gears. For example, the disclosed structure of a multi-purpose adjustable wrench (CN88210255U) is a typical example of a conventional adjustable wrench. By vertically rotating the worm gear, the adjustable mouth can be moved to adjust the opening. This adjustment method is limited and cannot meet the needs of different users. Furthermore, because the worm gear teeth are fine, the worm gear needs to rotate multiple times during adjustment, resulting in slow adjustment speed. Currently, there is no good solution to these problems.

[0003] In summary, the problem of how to change the rotation direction of the worm gear in an adjustable wrench and improve the adjustment speed has become a technical challenge that urgently needs to be solved in the industry. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this utility model provides a horizontally rotating adjustable wrench, which solves the problems of slow speed and low efficiency of traditional hexagonal wrenches when adjusting the opening amount.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A laterally adjustable adjustable wrench includes a wrench body and a movable nozzle. The wrench body has a slot at its head, and the movable nozzle is placed in the slot. A worm gear groove is provided near the slot at the head of the wrench body. A worm gear is installed in the worm gear groove by a bolt. The bolt restricts the vertical displacement of the worm gear, and the worm gear rotates around the bolt in the lateral direction. The bottom of the movable nozzle has movable nozzle teeth, and the side of the worm gear near the movable nozzle has helical teeth. The helical teeth mesh with the movable nozzle teeth.

[0006] The worm gear groove is provided through, and the side of the worm gear extends to the outside of the worm gear groove.

[0007] The outer surface of the worm gear is provided with anti-slip texture.

[0008] The bottom of the worm gear groove is provided with a threaded hole, the worm gear is provided with a countersunk groove and a central hole, the tail of the bolt passes through the central hole and is threadedly connected to the threaded hole, and the head of the bolt is located in the countersunk groove.

[0009] The inner wall of the slot is provided with an enlarged hole for the bolt head to pass through.

[0010] The bolts are internal hex bolts.

[0011] The outer end of the spiral tooth is open.

[0012] The present invention adopts the above solution and has the following beneficial effects: By providing a worm gear groove at the head of the wrench body, a worm gear is installed in the worm gear groove via bolts. The bolts can limit the vertical displacement of the worm gear, while the worm gear can rotate horizontally around the bolts. Since the helical teeth on the side of the worm gear mesh with the teeth of the movable nozzle at the bottom of the movable nozzle, the horizontal rotation of the worm gear can drive the movable nozzle to move within the groove, thereby adjusting the opening amount. This changes the rotation direction of the worm gear, which can meet the usage experience of different customer groups. Moreover, the diameter of the helical teeth is relatively large, and the movable nozzle can move a large distance with one horizontal rotation of the worm gear, thereby improving the speed of opening amount adjustment.

Detailed Implementation

[0018] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0019] like Figure 1-4 As shown, a laterally adjustable wrench includes a wrench body 1 and a movable mouth 2. The head of the wrench body 1 has a slot 3, and the movable mouth 2 is placed in the slot 3. The head of the wrench body 1 has a worm gear groove 4 near the slot 3. A worm gear 6 is installed in the worm gear groove 4 by a bolt 5. The bolt 5 restricts the vertical displacement of the worm gear 6, and the worm gear 6 can rotate in the lateral direction around the bolt 5. The bottom of the movable mouth 2 has a movable mouth tooth 7, and the side of the worm gear 6 near the movable mouth 2 has a helical tooth 8, while the other side is a flat surface. The helical tooth 8 meshes with the movable mouth tooth 7.

[0020] The worm gear groove 4 is provided through, and the side of the worm gear 6 extends to the outside of the worm gear groove 4, making it convenient for the operator to rotate the worm gear 6 with their fingers.

[0021] The outer surface of the worm gear 6 is provided with anti-slip texture 9, which can prevent slippage.

[0022] The bottom of the worm gear groove 4 is provided with a threaded hole 10, and the worm gear 6 is provided with a countersunk groove 11 and a central hole 12. The tail of the bolt 5 passes through the central hole 12 and is threadedly connected to the threaded hole 10, and the head of the bolt 5 is located in the countersunk groove 11. By tightening the tail of the bolt 5 to an appropriate depth in the threaded hole 10, the vertical displacement of the head of the bolt 5 is restricted, and the worm gear 6 is fitted onto the smooth part of the bolt 5 and can rotate around the bolt 5 in the lateral direction.

[0023] The inner wall of the slot 3 is provided with an enlarged hole 13 for the head of the bolt 5 to pass through, so that the bolt 5 can be inserted from the enlarged hole 13 and the installation is convenient.

[0024] Bolt 5 is an internal hex bolt.

[0025] The outer end of the spiral tooth 8 is open. When the spiral tooth 8 rotates, the movable mouth tooth 7 can be disengaged from the spiral tooth 8. After disengagement, the movable mouth 2 can be disassembled.

[0026] Working principle: When adjusting the opening amount, simply rotate the worm gear 6 horizontally. Since the helical teeth 8 on the side of the worm gear 6 mesh with the movable teeth 7 at the bottom of the movable mouth 2, the worm gear 6 can drive the movable mouth 2 to move within the slot 3, thereby achieving the purpose of adjusting the opening amount. Changing the rotation direction of the worm gear 6 can meet the usage experience of different customer groups. Moreover, the diameter of the helical teeth 8 is relatively large, and the movable mouth 2 can move a large distance with one horizontal rotation of the worm gear 6, thereby improving the adjustment speed of the opening amount.

[0027] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0028] Any aspects of this utility model not described in detail are known to those skilled in the art.
