Therefore, even if they can be disassembled, they may not be able to be reassembled; at this time, if the corresponding function of the damaged accessory is still needed, you can only buy a new multi-function pliers, which causes the overlap of other functions of the product and waste of resources. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiency of the prior art that the multifunctional pliers cannot flexibly replace a certain functional module therein, and to provide a multifunctional pliers accessory with a replaceable functional module. According to the needs of the user, when a functional module is damaged, the product can be reused by only replacing the functional module, but using the same accessory and the same multifunctional pliers body, thereby avoiding product overlap and reducing waste of resources.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A multifunctional pliers accessory with a replaceable functional module is provided, comprising an accessory seat, a multifunctional module, a locking block, a locking pin, and a limiting plate, wherein the multifunctional module is plugged into the accessory seat, the locking block is movably mounted on the accessory seat, the limiting plate is fixedly mounted on the accessory seat, the limiting plate is located beside the locking block, the locking pin passes through the locking block and the limiting plate, and the locking pin is rotatably connected to the limiting plate, the locking pin is also movably connected to the limiting plate and is detachably connected to the locking block; when the locking pin is rotated to a locked state, the locking block is engaged with the multifunctional module; when the locking pin is rotated to an unlocked state, the locking block can be pushed to move relative to the accessory seat to disengage the locking block from the multifunctional module.

[0006] The utility model realizes locking and unlocking of the multifunctional module by the locking block through the cooperation of the locking pin, the locking block and the limiting plate, so that the multifunctional module can be locked when it is in use; and when the multifunctional module needs to be replaced, it can be unlocked and replaced, thereby realizing a structure in which the functional modules can be replaced on the accessories of a multifunctional pliers, for example, replacing functional modules such as saws, files, rope cutters, etc. Specifically, the accessory seat is used to provide installation space for the locking block, locking pin, and limiting plate, and the multi-function module is installed and fixed by utilizing the locking block and the multi-function module's card connection and limiting function; the locking pin is rotatable, and the limiting plate is used to limit the locking pin. When the locking pin cannot move relative to the limiting plate, the locking block is also restricted and cannot move, so it always maintains its card connection with the multi-function module; when the locking pin is rotated so that the locking pin can move relative to the limiting plate, the locking block can be driven to move relative to the multi-function module, thereby disengaging the locking block from the multi-function module and releasing the card connection between the two; therefore, the utility model can realize the reuse of the multi-function pliers according to the needs of users by only replacing the functional modules, but using the same accessory and the same multi-function pliers body, thereby avoiding product overlap and reducing waste of resources.

[0007] Furthermore, the position-limiting plate is provided with an upper locking hole and an unlocking hole that are interconnected, the aperture of the upper locking hole is larger than the aperture of the unlocking hole, the outer diameter of the locking pin in the first direction is smaller than the aperture of the upper locking hole and larger than the aperture of the unlocking hole, and the outer diameter of the locking pin in the second direction is smaller than the aperture of the unlocking hole. When the locking pin is located in the upper locking hole and cannot enter the unlocking hole, it is in a locked state; when the locking pin is located in the unlocking hole, it is in an unlocked state. By setting the apertures of the upper locking hole and the unlocking hole accordingly, when the locking pin is located in the upper locking hole, it cannot move relative to the position-limiting plate, so it cannot drive the lock block to move, thereby ensuring the locked state between the lock block and the multi-function module, so that the multi-function module can be fixed in the accessory seat; and when the locking pin is located in the unlocking hole, the locking pin can move relative to the position-limiting plate, thereby driving the lock block to move, so that the locking block and the multi-function module are released from the clamping relationship, and the multi-function module can be removed and replaced from the accessory seat.

Figures 4 to 10 When the lock pin 4 is rotated to the locked state, the lock block 3 is engaged with the multi-function module 2; when the lock pin 4 is rotated to the unlocked state, the lock block 3 can be pushed to move relative to the accessory seat 1 so that the lock block 3 and the multi-function module 2 are disengaged.

[0037] The utility model realizes locking and unlocking of the multifunctional module 2 by the locking block 3 through the cooperation of the locking pin 4, the locking block 3 and the limiting plate 5, so that the multifunctional module 2 can be locked when it is in use; and when the multifunctional module 2 needs to be replaced, it can be unlocked and replaced, thus realizing a structure in which a functional module can be replaced on the accessories of a multifunctional pliers. This functional module can be a functional module that realizes the same function as the original one and needs to be replaced due to damage, or it can be a module that realizes other functions, thus enriching the diversity of the multifunctional pliers; for example, it can replace functional modules such as saws, files, and rope cutters. Specifically, the accessory seat 1 is used to provide installation space for the locking block 3, the locking pin 4, and the limiting plate 5, and the multifunctional module 2 is installed and fixed by using the locking block 3 and the limiting position of the multifunctional module 2; see Figure 4 and Figure 5 The lock pin 4 is rotatable, and the limiting piece 5 is used to limit the lock pin 4. When the lock pin 4 cannot move relative to the limiting piece 5, the lock block 3 is also restricted and cannot move, so it always maintains its engagement with the multi-function module 2; Figures 6 to 9 When the lock pin 4 is rotated so that the lock pin 4 can move relative to the limit plate 5, the lock block 3 can be driven to move relative to the multi-function module 2, thereby disengaging the lock block 3 from the multi-function module 2 and releasing the clamping relationship between the two. Fig.10 , and then pull out the multi-function module 2 to realize the disassembly and replacement of the multi-function module 2. Therefore, the utility model can realize the addition of the function of the multi-function pliers or the maintenance of the original function of the multi-function pliers according to the needs of the user, only by replacing the functional modules, but using the same accessories and the same multi-function pliers body, thereby avoiding product overlap and reducing waste of resources.

[0038] Preferably, see Figure 5The locking block 3 is provided with a first limiting portion 32, and the multifunctional module 2 is provided with a second limiting portion 21. The first limiting portion 32 can be engaged with the second limiting portion 21 for limiting. Preferably, the first limiting portion 32 is a protrusion, and the second limiting portion 21 is a groove. Of course, the first limiting portion 32 can also be a groove, and the second limiting portion 21 can be a protrusion. The locking block 3 and the multifunctional module 2 can be engaged with each other for limiting by the cooperation between the protrusion and the groove.

[0039] For details, see Figure 6 and Figure 8 The limiting plate 5 is provided with an upper locking hole 51 and an unlocking hole 52 which are interconnected. The aperture of the upper locking hole 51 is larger than the aperture of the unlocking hole 52. Fig.12 The outer diameter of the lock pin 4 in the first direction, i.e., direction A, is smaller than the aperture of the upper lock hole 51 and larger than the aperture of the unlocking hole 52. The outer diameter of the lock pin 4 in the second direction, i.e., direction B, is smaller than the aperture of the unlocking hole 52. When the lock pin 4 is located in the upper lock hole 51 and cannot enter the unlocking hole 52, it is in the locked state; when the lock pin 4 is located in the unlocking hole 52, it is in the unlocking state. By setting the apertures of the upper lock hole 51 and the unlocking hole 52 accordingly, when the lock pin 4 is located in the upper lock hole 51, it cannot move relative to the limiting piece 5, so it cannot drive the lock block 3 to move, thereby ensuring the locked state between the lock block 3 and the multi-function module 2, so that the multi-function module 2 can be fixed in the accessory seat 1; and when the lock pin 4 is located in the unlocking hole 52, the lock pin 4 can move relative to the limiting piece 5, thereby driving the lock block 3 to move, so that the lock block 3 and the multi-function module 2 are released from the clamping relationship, and then the multi-function module 2 can be removed and replaced from the accessory seat 1. The upper locking hole 51 and the unlocking hole 52 are connected to each other. When locking, since the outer diameter of the locking pin 4 in the first direction is smaller than the aperture of the upper locking hole 51 and larger than the aperture of the unlocking hole 52, the locking pin 4 cannot enter the unlocking hole 52; when unlocking is required, it is only necessary to rotate the locking pin 4 to a certain angle, preferably 90 degrees, in the upper locking hole 51, so that the axis of the locking pin 4 in the second direction is parallel to the axis of the unlocking hole 52. Since the outer diameter of the locking pin 4 in the second direction is smaller than the aperture of the unlocking hole 52, the locking pin 4 can be pushed to enter the unlocking hole 52 at this time, so that the locking pin 4 can move relative to the limiting plate 5, thereby driving the locking block 3 to move away from the multi-function module 2.

[0040] It also includes an elastic member 6. The accessory seat 1 is recessed with a mounting position 11. The locking block 3 and the elastic member 6 are both installed at the mounting position 11.

When in the locked state, the elastic member 6 is in the original state, at this time, the locking block 3 is engaged with the multi-function module 2; when in the unlocked state, and the locking block 3 is driven by the locking pin 4 to move away from the multi-function module 2, the elastic member 6 is compressed and generates a restoring force. If the locking pin 4 is released at this time, the locking block 3 will drive the locking pin 4 to move toward the multi-function module 2 under the action of the restoring force. If the multi-function module 2 has been replaced at this time, the locking block 3 can be engaged with the new multi-function module 2 to limit the position, so that the multi-function module 2 can be installed and fixed; such a setting can ensure that when the locking pin 4 or the locking block 3 is not affected by external force, the locking block 3 is always in the position engaged with the multi-function module 2, thereby ensuring the reliability of the connection between the multi-function module 2 and the accessory seat 1, and ensuring that the multi-function module 2 will not be separated from the accessory seat 1, so as to realize the function of the multi-function module 2.

[0041] Furthermore, there are two elastic members 6, the lock block 3 is provided with a lock pin hole 31, and the lock block 3 is provided with limit steps 33 along both sides of the lock pin hole 31, and the ends of the two elastic members 6 are respectively connected or abutted with the two limit steps 33. The lock pin 4 passes through the lock pin hole 31 and then passes through the upper lock hole 51 or the unlocking hole 52 for installation; the two elastic members 6 are respectively arranged on both sides of the lock pin hole 31, that is, located on both sides of the lock pin 4. When the elastic member 6 applies a restoring force to the lock block 3, the lock block 3 can be subjected to a more balanced force, avoiding the deviation of its movement due to unilateral force, and then the occurrence of a jamming phenomenon.

[0042] Moreover, an abutment position 12 is provided on the installation position 11, and the side of the limiting step 33 away from the elastic member 6 abuts against the abutment position 12. The abutment position 12 is a structure matching the limiting step 33, and the limiting step 33 is abutted and limited by the abutment position 12 to improve the reliability of the locking block 3 when it is installed in the accessory seat 1.

[0043] As an improvement of the present embodiment, the accessory seat 1 is provided with a slot 13, which is located beside the mounting position 11 and communicated with the mounting position 11, the end of the multifunctional module 2 is plugged into the slot 13, and the second limiting portion 21 is located at the position where the slot 13 is connected to the mounting position 11, and the first limiting portion 32 can extend from the mounting position 11 into the slot 13 and be engaged with the second limiting portion 21.

[0045] The following is Example 2 of a multifunctional pliers accessory with replaceable functional modules of the utility model. This example is similar to Example 1, except that the lock pin 4 includes a gripping portion 41 and a rotating portion 42 connected to each other, and the gripping portion 41 partially protrudes from the accessory seat 1, and the rotating portion 42 is threadedly connected to the locking block 3 and plugged into the limiting piece 5. Preferably, the gripping portion 41 is a circular structure, which is convenient for rotating the lock pin 4 and for threading the gripping portion 41 with the locking block 3. Rotating the gripping portion 41 can drive the rotating portion 42 to rotate, thereby changing its position in the unlocking hole 52, so that the lock pin 4 can be switched between the locked and unlocked states. After the rotating part 42 rotates a certain angle, in the unlocked state, the locking pin 4 can drive the locking block 3 to disengage from the multi-functional module 2, so that the multi-functional module 2 can be replaced. After replacing the new multi-functional module 2, the locking block 3 can be used to lock it. During the whole process, the rotating part 42 always remains connected with the locking block 3 to avoid the loss of parts due to the separation of the locking pin 4 and the accessory seat 1 or the locking block 3 and the accessory seat 1; the limiting plate 5 can be fixed to the accessory seat 1 by welding, and the locking block 3 is installed between the limiting plate 5 and the accessory seat 1, so the locking block 3 will not be lost.

[0046] Furthermore, a gasket 7 is included, which is sleeved outside the rotating part 42, and one end of the gasket 7 abuts against the locking block 3, and the other end abuts against the holding part 41.
