Description

Technical Field

[0001] This utility model relates to the field of wrench technology, and in particular to a swing-locking wrench. Background Technology

[0002] For example, publication number "CN217372150U" discloses "an installation wrench for corrugated beam steel guardrails," comprising: a handle, the handle being a slender plate-like structure, with a connecting seat at one end; a retaining sleeve, the retaining sleeve having a locking slot for relatively fixedly fitting onto a fastener, the retaining sleeve having a connecting part that connects to the connecting seat; wherein, the connecting seat has a slot with an outward opening along the length direction of the handle, the connecting part being a protrusion extending away from the center of the locking slot, the connecting part extending into the slot, and the connecting part and the slot being rotatably connected by a rotating shaft, the axis of the rotating shaft being parallel to the plane where the handle is located, and the rotating shaft being perpendicular to the length direction of the handle. However, in practical applications, this type of rotatable handle requires angle locking, which is cumbersome and requires additional tightening, making it inconvenient to operate. Summary of the Invention

[0003] In view of the problem mentioned in the background art that the method of locking the handle angle is relatively cumbersome, this utility model provides a swing-locking wrench, which makes locking the handle angle more convenient and quick, reduces the extra operation in the process, and improves work efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] A swing-lock wrench includes a wrench head and a handle, the wrench head and handle being rotatably connected. A locking unit is located on the wrench head near the handle, and a limiting unit is located on the handle near the wrench head. The limiting unit is connected to a reset unit, which is mounted on the handle. The limiting unit is slidably connected to the handle, and when it slides within the handle, it can switch between an engaged / disengaged state with the locking unit. In some applications, the wrench's rotation arc may be blocked or restricted by nearby objects or structures. Wrench designs have been created to allow users to change the angle of at least a portion of the wrench head relative to the handle. These wrenches are often described as having a flexible head or a flexible handle. Several flexible handle wrenches are currently available on the market, overcoming the obstacle problem in a plane parallel to the wrench head. By allowing the operator to adjust the angular position of the handle orthogonal to the plane of the wrench head, the operator can manipulate the wrench handle to avoid obstacles. However, how to lock the wrench head at a certain angle relative to the handle is one of the problems that needs to be solved. To address the aforementioned issues, this application, while ensuring the handle can rotate relative to the wrench head, includes a limiting unit and a locking unit that can engage and constrain each other between the handle and the wrench head. The limiting unit is located on the handle, while the locking unit is located on the wrench head. Furthermore, a reset unit is connected to the limiting unit. The reset unit can be a manual reset unit, including but not limited to push rods, push pins, and sliding pins, or an elastic reset unit, including but not limited to springs, elastic blocks, and elastic sponges. Since the limiting unit is slidably connected inside the handle, the reset unit can drive the limiting unit to slide within the handle. The limiting unit can be manually pushed; therefore, under manual pushing and the reset action of the reset unit, the limiting unit can... The handle can switch between different states as needed. The limiting unit and the engaging unit have two states: engaged and disengaged. During use, the limiting unit can switch between these two states by manual pressing and the action of the reset unit. When the limiting unit and the engaging unit are engaged, they lock together, ensuring a stable limiting effect between the handle and the wrench head. When the reset unit is activated, the limiting unit and the engaging unit are disengaged, and the locking effect disappears, allowing the handle to rotate relative to the wrench head, thus adjusting the handle's angle.

[0006] Preferably, the engaging unit includes engaging teeth, and the limiting unit includes limiting teeth, wherein the engaging teeth and the limiting teeth can mesh with each other. The engaging teeth on the engaging unit and the limiting teeth on the limiting unit ensure the stability of the engaging connection between the limiting unit and the engaging unit through the meshing between the engaging teeth and the limiting teeth.

[0007] Preferably, a rotating pin is provided between the wrench head and the handle, and the engaging unit includes a geared disc coaxial with the rotating pin, with engaging teeth arranged around the edge of the geared disc. Since the handle can rotate around the wrench head, it synchronously drives the limiting unit to rotate relative to the engaging unit during rotation. Therefore, the entire edge of the geared disc in the engaging unit is provided with engaging teeth, ensuring that the meshing relationship between the limiting teeth and the engaging teeth is maintained at any position during the rotation of the limiting unit. This guarantees that the engaging connection can be completed between the limiting unit and the engaging unit at any rotational position of the limiting unit.

[0008] Preferably, the limiting teeth are only provided on the side of the limiting unit closest to the engaging unit. Since engaging teeth are provided on all circumference of the gear disc, and the limiting unit remains engaged with the engaging unit on the side closest to it as the handle rotates, it is only necessary to provide limiting teeth on the side of the limiting unit closest to the engaging unit.

[0009] Preferably, the handle is provided with a limiting pin, and the limiting unit has a slotted hole through which the limiting pin passes. By providing a limiting pin on the handle and connecting it to the limiting unit via the slotted hole, the limiting unit can be limited and constrained during sliding within the handle, thus ensuring the stability of its circumferential position.

[0010] Preferably, the limiting unit includes a limiting disc and a movable disc, the limiting disc being larger than the movable disc. The limiting disc can engage with the engaging unit, and when the movable disc is aligned with the engaging unit, the limiting unit and the engaging unit are in a separated state. The limiting unit includes a limiting disc and a movable disc, wherein the limiting disc is provided with limiting teeth. By aligning the limiting disc with the engaging unit, an engaging connection between the limiting unit and the engaging unit can be achieved. Because the movable disc is smaller than the limiting disc, during use, when the movable disc is aligned with the engaging unit, the limiting unit and the engaging unit are in a separated state, allowing the handle to rotate freely relative to the wrench head.

[0011] Preferably, the movable disc is positioned on the side of the limiting disc away from the reset unit. Positioning the movable disc on the side of the limiting disc away from the reset unit allows the reset unit to be compressed and the limiting unit to move when the limiting unit is pressed, aligning the movable disc with the engaging unit. This enables the handle to be turned. Once the handle is rotated to the desired position, releasing the pressure on the limiting unit allows it to reset itself through the reset effect of the reset unit, aligning the limiting disc with the engaging unit and limiting the position of the handle.

[0012] Preferably, an adjustment button is provided on the side of the movable plate away from the limiting plate. Pressing the adjustment button will cause the limiting unit to slide within the handle. Providing an adjustment button on the side of the movable plate away from the limiting plate allows the operator to easily press and adjust the position, improving operational convenience.

[0013] Preferably, the reset unit is a spring, with one end of the spring abutting against the limiting unit and the other end abutting against the handle. By setting the reset unit as a spring, a self-resetting effect is achieved.

[0014] Preferably, the limiting unit has a placement groove at its end, and the spring end is connected to the placement groove. By providing the placement groove on the limiting unit, the spring is limited and constrained, thereby ensuring the positional stability of the spring and preventing it from shifting during the reset process, which would affect the reset stability.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) It makes locking the handle angle more convenient and quick, reduces extra operations in the process, and improves work efficiency;

[0017] (2) It can achieve flexible and fast angle adjustment and self-locking effect, which improves the smoothness and convenience of the operator's use and ensures the stability of the handle angle adjustment. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1:

[0027] like Figure 1 , 2As shown, a swing-lock wrench includes a wrench head 1 and a handle 2. The wrench head 1 and the handle 2 are rotatably connected. A locking unit 11 is provided on the side of the wrench head 1 near the handle 2, and a limiting unit 21 is provided on the side of the handle 2 near the wrench head 1. The limiting unit 21 is connected to a reset unit 22, which is disposed on the handle 2. The limiting unit 21 is slidably connected to the handle 2. When the limiting unit 21 slides within the handle 2, it can switch between an engaged or disengaged state with the locking unit 11. In some applications, the wrench's rotation arc may be blocked or restricted by nearby objects or structures. Wrench designs have been created to allow users to change the angle of at least a portion of the wrench head 1 relative to the handle 2. These wrenches are typically described as having a flexible head or a flexible handle 2. Currently, various flexible handle 2 wrenches are available on the market, overcoming the problem of obstacles in a plane parallel to the wrench head 1. By allowing the operator to adjust the angular position of the handle 2 orthogonal to the plane of the wrench head 1, the operator can manipulate the handle 2 of the wrench to avoid obstacles. However, how to lock the wrench head 1 at a certain angle relative to the handle 2 is one of the problems that needs to be solved. To address this problem, in this application, based on the premise that the handle 2 can rotate relative to the wrench head 1, a limiting unit 21 and a locking unit 11 that can mutually engage and constrain each other are provided between the handle 2 and the wrench head 1. The limiting unit 21 is located on the handle 2, while the locking unit 11 is located on the wrench head 1. Furthermore, a reset unit 22 is connected to the limiting unit 21. The reset unit 22 can be a manual reset unit 22, including but not limited to push rods, push pins, sliding pins, etc., or it can be an elastic reset unit 22, including but not limited to springs, elastic blocks, elastic sponges, etc. Since the limiting unit 21 is slidably connected inside the handle 2, the reset unit 22 can drive the limiting unit 21 to slide inside the handle 2. The limiting unit 21 can be manually pushed. Therefore, under the manual pushing and the reset action of the reset unit 22, the limiting unit... 21 can switch between different states inside the handle 2 as needed. The limiting unit 21 and the engaging unit 11 have two states: engaging and disengaged. During use, the limiting unit 21 can switch between these two states by manual pressing and the action of the reset unit 22. Since the limiting unit 21 and the engaging unit 11 can engage, when the limiting unit 21 is in the engaging state, it engages with the engaging unit 11, thus ensuring a stable limiting effect between the handle 2 and the wrench head 1. When the reset unit 22 is activated, the limiting unit 21 and the engaging unit 11 are in the disengaged state, so the engaging effect between the limiting unit 21 and the engaging unit 11 disappears, allowing the handle 2 to rotate relative to the wrench head 1, thereby adjusting the angle of the handle 2.

[0028] like Figure 2 As shown, the engaging unit 11 includes engaging teeth 111, and the limiting unit 21 includes limiting teeth 211. The engaging teeth 111 and the limiting teeth 211 can mesh with each other. The engaging teeth 111 are provided on the engaging unit 11, and the limiting teeth 211 are provided on the limiting unit 21. Through the meshing between the engaging teeth 111 and the limiting teeth 211, the stability of the engaging connection between the limiting unit 21 and the engaging unit 11 is ensured.

[0029] like Figure 2 , 3 As shown, a rotating pin 12 is provided between the wrench head 1 and the handle 2. The engaging unit 11 includes a gear disk 13 coaxial with the rotating pin 12, and engaging teeth 111 are arranged around the edge of the gear disk 13. Since the handle 2 can rotate around the wrench head 1, the handle 2 synchronously drives the limiting unit 21 to rotate relative to the engaging unit 11 during the rotation. Therefore, the entire edge of the gear disk 13 of the engaging unit 11 is provided with engaging teeth 111, which ensures that the meshing relationship between the limiting teeth 211 and the engaging teeth 111 can be maintained at any position during the rotation of the limiting unit 21. This ensures that the engaging connection between the limiting unit 21 and the engaging unit 11 can be completed at any rotational position of the limiting unit 21.

[0030] like Figure 3 As shown, the limiting tooth 211 is only provided on the side of the limiting unit 21 near the engaging unit 11. The limiting tooth 211 is provided on the side of the engaging unit 11. Since the engaging teeth 111 are provided on all circumferences of the gear plate 13, and since the limiting unit 21 always remains in contact with the engaging unit 11 on the side near the engaging unit 11 as the handle 2 rotates, it is only necessary to provide the limiting tooth 211 on the side of the limiting unit 21 near the engaging unit 11.

[0031] Example 2:

[0032] like Figure 1 , 2As shown, a swing-lock wrench includes a wrench head 1 and a handle 2. The wrench head 1 and the handle 2 are rotatably connected. A locking unit 11 is provided on the side of the wrench head 1 near the handle 2, and a limiting unit 21 is provided on the side of the handle 2 near the wrench head 1. The limiting unit 21 is connected to a reset unit 22, which is disposed on the handle 2. The limiting unit 21 is slidably connected to the handle 2. When the limiting unit 21 slides within the handle 2, it can switch between an engaged or disengaged state with the locking unit 11. In some applications, the wrench's rotation arc may be blocked or restricted by nearby objects or structures. Wrench designs have been created to allow users to change the angle of at least a portion of the wrench head 1 relative to the handle 2. These wrenches are typically described as having a flexible head or a flexible handle 2. Currently, various flexible handle 2 wrenches are available on the market, overcoming the problem of obstacles in a plane parallel to the wrench head 1. By allowing the operator to adjust the angular position of the handle 2 orthogonal to the plane of the wrench head 1, the operator can manipulate the handle 2 of the wrench to avoid obstacles. However, how to lock the wrench head 1 at a certain angle relative to the handle 2 is one of the problems that needs to be solved. To address this problem, in this application, based on the premise that the handle 2 can rotate relative to the wrench head 1, a limiting unit 21 and a locking unit 11 that can mutually engage and constrain each other are provided between the handle 2 and the wrench head 1. The limiting unit 21 is located on the handle 2, while the locking unit 11 is located on the wrench head 1. Furthermore, a reset unit 22 is connected to the limiting unit 21. The reset unit 22 can be a manual reset unit 22, including but not limited to push rods, push pins, sliding pins, etc., or it can be an elastic reset unit 22, including but not limited to springs, elastic blocks, elastic sponges, etc. Since the limiting unit 21 is slidably connected inside the handle 2, the reset unit 22 can drive the limiting unit 21 to slide inside the handle 2. The limiting unit 21 can be manually pushed. Therefore, under the manual pushing and the reset action of the reset unit 22, the limiting unit... 21 can switch between different states inside the handle 2 as needed. The limiting unit 21 and the engaging unit 11 have two states: engaging and disengaged. During use, the limiting unit 21 can switch between these two states by manual pressing and the action of the reset unit 22. Since the limiting unit 21 and the engaging unit 11 can engage, when the limiting unit 21 is in the engaging state, it engages with the engaging unit 11, thus ensuring a stable limiting effect between the handle 2 and the wrench head 1. When the reset unit 22 is activated, the limiting unit 21 and the engaging unit 11 are in the disengaged state, so the engaging effect between the limiting unit 21 and the engaging unit 11 disappears, allowing the handle 2 to rotate relative to the wrench head 1, thereby adjusting the angle of the handle 2.

[0033] like Figure 2 , 3 As shown, the engaging unit 11 includes engaging teeth 111, and the limiting unit 21 includes limiting teeth 211. The engaging teeth 111 and the limiting teeth 211 can mesh with each other. The engaging teeth 111 are provided on the engaging unit 11, and the limiting teeth 211 are provided on the limiting unit 21. Through the meshing between the engaging teeth 111 and the limiting teeth 211, the stability of the engaging connection between the limiting unit 21 and the engaging unit 11 is ensured.

[0034] like Figure 3 As shown, a rotating pin 12 is provided between the wrench head 1 and the handle 2. The engaging unit 11 includes a gear disk 13 coaxial with the rotating pin 12, and engaging teeth 111 are arranged around the edge of the gear disk 13. Since the handle 2 can rotate around the wrench head 1, the handle 2 synchronously drives the limiting unit 21 to rotate relative to the engaging unit 11 during the rotation. Therefore, the entire edge of the gear disk 13 of the engaging unit 11 is provided with engaging teeth 111, which ensures that the meshing relationship between the limiting teeth 211 and the engaging teeth 111 can be maintained at any position during the rotation of the limiting unit 21. This ensures that the engaging connection between the limiting unit 21 and the engaging unit 11 can be completed at any rotational position of the limiting unit 21.

[0035] like Figure 3 As shown, the limiting tooth 211 is only provided on the side of the limiting unit 21 near the engaging unit 11. The limiting tooth 211 is provided on the side of the engaging unit 11. Since the engaging teeth 111 are provided on all circumferences of the gear plate 13, and since the limiting unit 21 always remains in contact with the engaging unit 11 on the side near the engaging unit 11 as the handle 2 rotates, it is only necessary to provide the limiting tooth 211 on the side of the limiting unit 21 near the engaging unit 11.

[0036] like Figure 3 As shown, a limit pin 23 is provided on the handle 2, and a strip hole 24 is provided in the limiting unit 21, through which the limit pin 23 passes. The limit pin 23 is provided on the handle 2 and connected to the limiting unit 21 through the strip hole 24, so that the limiting unit 21 can be limited and constrained by the limit pin 23 during the sliding process in the handle 2, thereby ensuring that the limiting unit 21 can always maintain the stability of its circumferential position.

[0037] like Figure 4As shown, the limiting unit 21 includes a limiting disc 25 and a movable disc 26. The limiting disc 25 is larger than the movable disc 26. The limiting disc 25 can engage with the engaging unit 11. When the movable disc 26 is aligned with the engaging unit 11, the limiting unit 21 and the engaging unit 11 are in a separated state. The limiting unit 21 includes a limiting disc 25 and a movable disc 26. The limiting disc 25 is provided with limiting teeth 211. By aligning the limiting disc 25 with the engaging unit 11, the limiting unit 21 and the engaging unit 11 can be engaged. However, since the movable disc 26 is smaller than the limiting disc 25, during use, when the movable disc 26 is aligned with the engaging unit 11, the limiting unit 21 and the engaging unit 11 are in a separated state, allowing the handle 2 to rotate flexibly relative to the wrench head 1.

[0038] like Figure 3 , 4 As shown, the movable disc 26 is positioned on the side of the limiting disc 25 away from the reset unit 22. Positioning the movable disc 26 on the side of the limiting disc 25 away from the reset unit 22 allows the limiting unit 21 to be pressed manually, thus squeezing the reset unit 22 and causing the limiting unit 21 to move. This aligns the movable disc 26 with the engaging unit 11, enabling the handle 2 to be turned. When the handle 2 is rotated to the appropriate position, releasing the pressure on the limiting unit 21 allows the limiting unit 21 to reset itself through the reset effect of the reset unit 22, aligning the limiting disc 25 with the engaging unit 11 and limiting the position of the handle 2.

[0039] like Figure 4 As shown, an adjustment button 27 is provided on the side of the movable plate 26 away from the limit plate 25. Pressing the adjustment button 27 can cause the limit unit 21 to slide within the handle 2. The adjustment button 27 is located on the side of the movable plate 26 away from the limit plate 25, which allows the operator to easily press and adjust the position, improving the convenience of operation.

[0040] like Figure 4 As shown, the reset unit 22 is a spring, with one end abutting against the limiting unit 21 and the other end abutting against the handle 2. By setting the reset unit 22 as a spring, a self-resetting effect is achieved.

[0041] like Figure 2 As shown, the limiting unit 21 has a placement groove 28 at its end, and the spring end is connected to the placement groove 28. The placement groove 28 on the limiting unit 21 limits and constrains the spring, thereby ensuring the positional stability of the spring and preventing the spring from shifting during the reset process, which would affect the reset stability.
