Description

Technical Field

[0001] This utility model relates to the field of tools, and in particular to a terminal crimping pliers. Background Technology

[0002] Terminal crimping pliers (also known as terminal crimping pliers) are a commonly used tool. The structure of the terminal crimping pliers currently in use is shown in patent publication document CN209434573U. The crimping pliers with this structure use two clamps located on the upper and lower sides for crimping. Because the two clamps are fixedly installed, the installation position between the two clamps cannot be adjusted as needed. Therefore, the size of the jaws of the crimping pliers with this structure cannot be adjusted as needed, resulting in poor adaptability of the crimping pliers. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a terminal crimping tool. Both the first and second jaws are equipped with serrated annular grooves. By utilizing the different grooves on the serrated annular grooves to engage with the locking post assembly, the positions of the first and second jaws can be adjusted, forming clamping jaws of different sizes, thus making the crimping tool more adaptable.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A terminal crimping tool includes a first clamp and a second clamp, which are rotatably coupled together. It also includes a push block, a first main clamp, a first auxiliary clamp, a second main clamp, a second auxiliary clamp, a first clamp head, a second clamp head, and a locking post assembly. The first main clamp and the first auxiliary clamp are disposed on the first clamp, the push block is slidably disposed on the second clamp, and the second main clamp and the second auxiliary clamp are disposed on the push block. The first main clamp and the first auxiliary clamp are parallel and do not contact each other. The locking post assembly is disposed between the first main clamp and the first auxiliary clamp, and between the second main clamp and the second auxiliary clamp. The first clamp head has a serrated annular groove, and the second clamp head has a serrated annular groove. The first clamp head is clamped between the first main clamp and the first auxiliary clamp, and the second clamp head is clamped between the second main clamp and the second auxiliary clamp. The locking post assembly is used to engage with the groove on the serrated annular groove.

[0006] In this type of terminal crimping pliers, a first clamping head is slidably disposed between a first main clamping block and a first auxiliary clamping block, and a second clamping head is disposed between a second main clamping block and a second auxiliary clamping block. A locking post assembly is disposed between the first main clamping block and the first auxiliary clamping block, and the first or second clamping head engages with the locking post assembly via its own serrated annular groove. Since the serrated annular groove is composed of multiple interconnected semi-circular grooves, the position of the first or second clamping head can be adjusted when different grooves engage with the locking post assembly. By adjusting the position of the first and second clamping heads, the clamping jaw size between them can be adjusted, resulting in better crimping adaptability.

[0007] In summary, this type of clamp features serrated annular grooves on both the first and second clamping heads. By utilizing the different grooves on the serrated annular grooves to engage with the engaging post assembly, the positions of the first and second clamping heads can be adjusted, allowing for the formation of clamping jaws of different sizes and enhancing the adaptability of the clamping forceps.

[0008] Optionally, the engaging post assembly includes a wide-diameter post and a narrow-diameter post, which are fixedly fitted together. The wide-diameter post is used to engage with the serrated annular groove, and a return spring is sleeved on the narrow-diameter post. One end of the return spring abuts against the end of the narrow-diameter post, and the other end of the return spring abuts against the first main clamping block or the second main clamping block.

[0009] The function of the return spring is to achieve elastic installation of the locking post assembly. Pressing the locking post assembly allows the wide-diameter post of the locking post assembly to slide out of the serrated ring groove. When the pressing force is removed, under the action of the return spring, the locking post assembly returns to its original position, and the wide-diameter post of the locking post assembly slides back into the serrated ring groove. In this way, by pressing the locking post assembly, the first or second jaw can be moved, and by removing the pressing force, the first or second jaw can be locked again.

[0010] Optionally, it also includes a linkage pull block, which is rotatably engaged with the second main clamping block and the second auxiliary clamping block. The linkage pull block is provided with a nested shaft, and a spreading spring is sleeved on the nested shaft. One end of the spreading spring abuts against the linkage pull block, and a stop post is provided on the first clamp handle. The other end of the spreading spring abuts against the spreading spring.

[0011] The function of the linkage block is to link the first and second clamp handles. When both hands press down on the first and second clamp handles, the first and second clamp handles are brought together. When the external force is removed, the first and second clamp handles are opened up again and returned to their original state under the action of the spring.

[0012] Optionally, it also includes a locking block, which is rotatably mounted on the first clamp handle via its own pivot, and a deflection spring is provided between the locking block and the first clamp handle. The deflection spring is in a stretched state. The push block is provided with a first engaging position and a second engaging position. The locking block is provided with a square-shaped locking part. Both the first engaging position and the second engaging position are triangular.

[0013] The function of the deflection spring is to enable the elastic rotation of the locking block. When the square locking part of the locking block is engaged with the first or second engagement position, the push block is locked and cannot move relative to the second clamp. When the locking part slides out from the first or second engagement position, the push block can move freely.

[0014] Optionally, the first locking position is connected to the second locking position, and the edges of the first locking position and the second locking position are both straight planes.

[0015] The straight plane at the edge of the first and second locking positions facilitates the sliding of the locking parts into and out of the locking positions.

[0016] Optionally, the second main clamping block and the second auxiliary clamping block are provided with connecting blocks, and the two ends of the connecting blocks are provided with linkage protrusions. The first clamping head is provided with a guide slide, and the linkage protrusions and the guide slide are slidably engaged together.

[0017] The linkage protrusion and the guide slide work together to ensure that the push block can slide stably in the predetermined direction.

[0018] Optionally, a stabilizing shaft is provided on one side of the engaging post assembly. The stabilizing shaft does not contact the engaging post assembly, but is used to contact the edge of the first or second clamping head.

[0019] The function of the stabilizing shaft is to contact the first jaw (or the second jaw) when it first slides into the engaging post assembly, thereby improving the stability of the first jaw during movement.

[0020] Optionally, the first and second pliers heads are identical in shape and size.

[0021] The beneficial effects of this utility model are: serrated ring grooves are provided on both the first and second jaws, and the different grooves on the serrated ring grooves engage with the locking post assembly, thereby achieving adjustable positions of the first and second jaws, forming clamping jaws of different sizes, and making the clamps more adaptable.

It also includes a push block 12, a first main clamping block 201, a first auxiliary clamping block 202, a second main clamping block 401, a second auxiliary clamping block 402, a first clamping head 301, a second clamping head 302, and a locking post assembly. The first main clamping block 201 and the first auxiliary clamping block 202 are disposed on the first clamping block 1. The push block 12 is slidably disposed on the second clamping block 9. The second main clamping block 401 and the second auxiliary clamping block 402 are disposed on the push block 12. The first main clamping block 201 and the first auxiliary clamping block 202 are parallel and do not contact each other. In the state where the second main clamping block 401 and the second auxiliary clamping block 402 are parallel and not in contact, a locking post assembly is provided between the first main clamping block 201 and the first auxiliary clamping block 202, a locking post assembly is provided between the second main clamping block 401 and the second auxiliary clamping block 402, a serrated annular groove 15 is provided on the first clamping head 301, a serrated annular groove 15 is provided on the second clamping head 302, the first clamping head 301 is clamped between the first main clamping block 201 and the first auxiliary clamping block 202, and the second clamping head 302 is clamped between the second main clamping block 401 and the second auxiliary clamping block 402, the locking post assembly is used to engage with the groove on the serrated annular groove 15.

[0033] In this type of terminal crimping pliers, a first clamping head 301 is slidably disposed between a first main clamping block 201 and a first auxiliary clamping block 202, and a second clamping head 302 is disposed between a second main clamping block 401 and a second auxiliary clamping block 402. A locking post assembly is also disposed between the first main clamping block 201 and the first auxiliary clamping block 202. The first clamping head 301 or the second clamping head 302 engages with the locking post assembly through its own serrated annular groove 15. Since the serrated annular groove 15 is composed of multiple interconnected semi-circular grooves, the position of the first clamping head 301 or the second clamping head 302 can be adjusted when different grooves engage with the locking post assembly. By adjusting the position of the first clamping head 301 and the second clamping head 302, the clamping size between them can be adjusted, resulting in better adaptability of the crimping pliers.

[0034] In summary, this type of clamp is provided with serrated annular grooves 15 on both the first clamp head 301 and the second clamp head 302. By utilizing the different grooves on the serrated annular grooves 15 to engage with the engaging post assembly, the positions of the first clamp head 301 and the second clamp head 302 can be adjusted, forming clamps of different sizes, thus making the clamp more adaptable.

[0035] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and appendix Figure 5 As shown, the engaging post assembly includes a wide-diameter post 602 and a narrow-diameter post 601. The wide-diameter post 602 and the narrow-diameter post 601 are fixedly engaged together. The wide-diameter post 602 is used to engage with the serrated annular groove 15. A return spring 7 is sleeved on the narrow-diameter post 601. One end of the return spring 7 abuts against the end of the narrow-diameter post 601, and the other end of the return spring 7 abuts against the first main clamping block 201 or the second main clamping block 401.

[0036] The function of the return spring 7 is to achieve elastic installation of the locking post assembly.
