Description

Technical Field

[0001] The utility model relates to a hand tool, in particular to a clamping device. Background Art

[0002] Crimping pliers, also known as crimping pliers or crimping pliers, are specialized tools used to crimp wires and connectors, and are commonly used in the electronics, electrical, and communications industries. Crimping pliers typically consist of a handle, a plier head, and a crimping die. The plier head is operated by the handle to open and close relative to each other. The crimping die is located within the plier head and has a corresponding die shape depending on the connector to be crimped. Examples of this type of crimping pliers include the clamping devices disclosed in Taiwan Patents I836981, M604262, and M549988.

[0003] Conventional crimping pliers have their crimping dies positioned on the pliers head via pins, making replacement of the crimping dies quite inconvenient as the pins need to be removed before replacement. However, the crimping pliers in the aforementioned patent have improved this aspect, allowing the user to release the crimping dies with a simple press.

[0004] However, the actual process of replacing the crimping die is still not simple, convenient and fast enough. Therefore, it is necessary to provide a novel and progressive clamping device to solve the above problems. Utility Model Content

[0060] The following examples are merely illustrative of possible implementations of the present invention and are not intended to limit the scope of protection to be provided by the present invention. The words "one" or "at least one" preceding the nouns mentioned herein do not limit the quantity and may be "plural" based on needs. Such changes in quantity also fall within the scope of protection to be provided, and are therefore clearly stated.

[0061] Please refer to Figures 1 to 9 , which shows an embodiment of the present invention. The clamping device of the present invention includes: a base 1, a clamp body 3 and a jaw module 4.

[0062] The base 1 includes a base 11 and a plurality of clamping units 2. The clamping units 2 are arranged linearly on the base 11 for ease of operation and viewing, and the linear arrangement occupies less space. Each clamping unit 2 includes two clamping members 21, which are relatively movable on the base 11 between a first position and a second position. Each clamping member 21 includes a clamping portion 22.

[0063] The pliers body 3 includes two gripping portions 31, two working heads 33 and two positioning members 34. The two gripping portions 31 are connected to each other so as to be relatively movably connected. The two working heads 33 are respectively provided on the two gripping portions 31 and can be relatively opened and closed. The two positioning members 34 are respectively provided on the two working heads 33 so as to be relatively movably connected between a locked state and a released state. Each positioning member 34 includes a positioning portion 35.

[0064] The jaw module 4 is rotatably assembled to one of the clamping unit 2 and the clamp body 3. The jaw module 4 includes two pressing modules 41. Each pressing module 41 includes a first connecting portion 42 and a second connecting portion 43. The first connecting portion 42 can be selectively engaged with the clamping portion 22, and the second connecting portion 43 can be selectively hooked with the positioning portion 35. The clamp body 3 can be assembled with the jaw module 4. When the two clamping members 21 clamp the two pressing modules 41, the clamping portions 22 of the two clamping members 21 are combined with the first connecting portion 42 of the two pressing modules 41, and the two clamping members 21 are in the first state. When the two clamping members 21 do not clamp the two pressing modules 41, the two clamping members 21 are in the second state. When the two positioning members 34 clamp the two pressing modules 41, the positioning portions 35 of the two positioning members 34 are combined with the second connecting portions 43 of the two pressing modules 41, and the two positioning members 34 are in the locked state. When the two positioning members 34 do not clamp the two pressing modules 41, the two positioning members 34 are in the released state.

[0065] Preferably, the number of the jaw modules 4 is plural, and the plural jaw modules 4 are respectively provided in the plural clamping units 2. The appearances of the plural jaw modules 4 are preferably different, so that the user can select the required jaw module 4 according to the situation.

[0066] When the jaw module 4 is to be transferred from the base body 1 to the jaw body 3, the two positioning members 34 in the release state can be inserted between the two clamping members 21 in the first state along a plug-in direction, so that the clamping parts 22 of the two clamping members 21 are disengaged from the first connecting parts 42 of the two pressing modules 41 to release the jaw module 4. At this time, the two positioning members 34 can be moved to the locking state to combine with the jaw module 4, thereby pulling the jaw module 4 out of the two clamping members 21.

[0067] On the contrary, when the jaw module 4 is to be transferred from the jaw body 3 to the base body 1, the two clamping members 21 in the second state can be inserted between the two positioning members 34 in the locked state in the opposite direction of the plug-in, so that the positioning parts 35 of the two positioning members 34 are disengaged from the second connecting parts 43 of the two pressure modules 41 to release the jaw module 4. At this time, the two clamping members 21 can be moved to the first state to combine with the jaw module 4, thereby pulling the jaw module 4 out of the two positioning members 34.

[0068] Preferably, each of the clamping units 2 further includes a first elastic member 24, which is elastically pressed between the two clamping members 21 to drive the clamping portions 22 of the two clamping members 21 to normally have a tendency to move closer together, so that the jaw module 4 can automatically clamp and position when it enters the two clamping members 21. Similarly, the clamp body 3 preferably further includes a second elastic member 36, which is elastically pressed between the two positioning members 34 to drive the positioning portions 35 of the two positioning members 34 to normally have a tendency to move closer together, so that the jaw module 4 can automatically clamp and position when it enters the two positioning members 34. In this way, when one of the pliers body 3 and the clamping unit 2 releases the jaw module 4, the other will automatically clamp the jaw module 4. The user only needs to hold the pliers body 3 and insert the two working heads 33 into the clamping unit 2 along the plug-in direction to complete the transfer of the jaw module 4, such as transferring it from the base body 1 to the pliers body 3. When the same action is performed again, the jaw module 4 will be transferred again, such as transferring it from the pliers body 3 to the base body 1. It is quite convenient and fast to use.

[0069] More specifically, each of the clamping members 21 can be pivotally mounted on the base 11 relative to each other, and each of the positioning members 34 can be pivotally mounted on one of the working heads 33 relative to each other. When the jaw module 4 is located on the base 1, the two clamping members 21 and the two pressing modules 41 form two first plug-in slots 51, and each of the clamping members 21 respectively forms one of the first plug-in slots 51 with one of the pressing modules 41. At this time, the two positioning members 34 and the two plug-in portions 333 of the two working heads 33 form two second plug-in slots 52, and each of the positioning members 34 respectively forms one of the second plug-in slots 52 with the plug-in portion 333 of the working head 33. Among them, when the jaw module 4 is to be transferred from the base body 1 to the jaw body 3, the two positioning members 34 in the released state are inserted into the two first plug-in slots 51, and at the same time, parts of the two pressing modules 41 are reversely inserted into the two second plug-in slots 52. During the movement, parts of the two pressing modules 41 will push open the two positioning members 34 in a direction perpendicular to the plug-in direction to indirectly drive the two clamping members 21 to move until the clamping parts 22 of the two clamping members 21 are disengaged from the first connecting parts 42 of the two pressing modules 41, and the positioning parts 35 of the two positioning members 34 are combined with the second connecting parts 43 of the two pressing modules 41, thereby completing the transfer and assembly of the jaw module 4.

[0070] More specifically, when the jaw module 4 is located on the jaw body 3, a clamping gap 23 is formed between the two clamping members 21. At this time, the two positioning members 34 and the two pressing modules 41 form two third plug-in slots 53, and each of the positioning members 34 forms one of the third plug-in slots 53 together with one of the pressing modules 41; wherein, when the jaw module 4 is to be transferred from the jaw body 3 to the base body 1, the two clamping members 21 in the second state can be inserted into the two third plug-in slots 53, and at the same time, part of the two pressing modules 41 is inserted into the clamping gap 23, and then the two clamping members 21 push open the two positioning members 34 until the positioning parts 35 of the two positioning members 34 are separated from the second connecting parts 43 of the two pressing modules 41, and the clamping parts 22 of the two clamping members 21 are combined with the first connecting parts 42 of the two pressing modules 41, thereby completing the transfer and assembly of the jaw module 4.

[0071] Preferably, each clamping unit 2 further includes two release members 25, which are movably provided on the base 11 and located at opposite ends of the clamping portions 22 of the two clamping members 21. The two release members 25 are controlled by the outside world and can selectively force the clamping portions 22 of the two clamping members 21 to move relatively apart, so as to facilitate the disassembly or replacement of the jaw module 4 of other shapes on the two clamping members 21 with bare hands.

[0072] It is worth mentioning that each pressing module 41 includes a sliding portion 44. Each working head 33 includes a connecting groove 331 and a body 332. The connecting groove 331 extends and is recessed in the body 332. The sliding portion 44 can be slidably connected to the connecting groove 331. The clamp body 3 also includes a positioning mechanism 37, which includes a stop portion 38 and a rest portion 39. The stop portion 38 is movable to a stop position and is provided on the body 332 of one working head 33, and the rest portion 39 is provided on the body 332 of the other working head 33. The stop portion 38 and the rest portion 39 move with the two working heads 33 respectively; wherein, when the stop portion 38 moves to the stop position, the stop portion 38 is located on the movement path of the rest portion 39, and then the stop portion 38 and the rest portion 39 will abut and stop each other at a predetermined position, so that the position of the assembly groove 331 of the two working heads 33 matches the position of the sliding portion 44 of the second pressing module 41 provided on the base body 1. In other words, the user only needs to make the two working heads 33 relatively close to each other to achieve the optimal position, and can easily and simply perform the transfer action of the jaw module 4.

[0073] In this embodiment, a recess 381 is provided on one side of the stopping portion 38 facing the abutting portion 39, and a block 391 is provided on one side of the abutting portion 39 facing the stopping portion 38. When the stopping portion 38 moves to the stopping position, the recess 381 is located on the movement path of the block 391. Then, when the abutting portion 39 swings to a predetermined position, the block 391 is embedded in the recess 381.

[0074] Preferably, the base 1 further includes a connecting portion 12, and a grip portion 31 is detachably plugged into the connecting portion 12, so that the pliers 3 are combined and positioned on the base 1, making it easy to store the pliers 3 when not in use or when going out.

[0075] Another preferred embodiment is that at least one of the two gripping portions 31 is recessed with at least one latching slot 311, and the base 1 further includes at least one operating member 13. The middle section of the at least one operating member 13 is positioned within the assembly portion 12. The opposing ends of the at least one operating member 13 are free and can be moved relative to the assembly portion 12 like a seesaw. One end of the at least one operating member 13 is provided with a latching protrusion 14, and the other end is provided for external pressure. The latching protrusion 14 of the at least one operating member 13 can extend into the interior of the assembly portion 12 to engage with the at least one latching slot 311, thereby enhancing the stability of the connection between the pliers 3 and the base 1. In this embodiment, the number of the at least one operating member 13 is two, and the two operating members 13 are integrally formed with the base 11.

[0076] In another preferred embodiment, the clamping device further includes a hanging member 6 connected to the base 1 and can be hung from a user's belt or tool belt. This allows the user to perform other tasks with both hands free when the clamping device is not in use. In this embodiment, the base 1 further includes a metal block 15 disposed on the base 11. The hanging member 6 is mounted on the metal block 15. The metal block 15 has a relatively strong structure, can withstand greater forces, and is relatively durable. The metal block 15 is located on the opposite side of the opening of the connecting portion 12.
