Description
Technical Field
[0001] The utility model relates to the technical field of tool pliers, and more specifically to a detachable pliers handle structure and a multifunctional tool pliers. Background Art
[0002] Multifunctional tool pliers on the market usually combine a plier head with a knife and a scissors to improve the diversity of the tool and meet the different needs of users. However, this type of tool pliers generally only has a plier handle module with one set function. In daily life, different functions may be used in different scenarios, which need to be achieved by replacing different plier handle modules. However, in existing multifunctional tool pliers, since the plier head and the plier handle module are non-detachable structures, it is impossible to simultaneously give a multifunctional tool pliers the functions of multiple plier handle modules. Users still need to purchase different pliers to achieve applications in different scenarios, resulting in a waste of resources and costs. Utility Model Content
[0003] The purpose of the utility model is to overcome the problem that the existing pliers head and the pliers handle module cannot be disassembled, and to provide a detachable pliers handle structure, which can facilitate the disassembly and replacement of the pliers handle module, so that the same pliers head can be suitable for pliers handle modules of various structures, thereby improving the utilization rate of the pliers head and reducing the waste of resources to a certain extent, enriching the diversity of tools.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A detachable pliers handle structure is used in tool pliers. The tool pliers include a pliers head, and the pliers handle structure is detachably connected to the pliers head; the pliers handle structure includes a pliers handle body, a locking assembly, and a rotating shaft assembly. The rotating shaft assembly is penetrated through the pliers handle body and the pliers head, and the locking assembly is movably mounted on the pliers handle body and can be clamped with the rotating shaft assembly.
[0006] The pliers head of the utility model is rotatably connected with the pliers handle body through a rotating shaft assembly, and the rotating shaft assembly is locked by a locking assembly, so that the rotating shaft assembly can always be inserted into the pliers head and the pliers handle body, so that the pliers head and the pliers handle body can be switched between a use state and a storage state. When the pliers head extends out of the pliers handle body and the end of the pliers head is farthest from the end of the pliers handle body, the pliers head is in an open state; rotating the pliers head can make the pliers head completely hidden in the pliers handle body, and the pliers head is in a storage state at this time. The locking assembly is movably connected with the pliers handle body, and the locking assembly can slide relative to the pliers handle body. The rotating shaft assembly can be locked or unlocked by changing the position of the locking assembly. When the locking assembly is engaged with the rotating shaft assembly, it is in a locked state, and the pliers head and the pliers handle body are always connected; when the locking assembly is released from the rotating shaft assembly, it is in an unlocked state, and the rotating shaft assembly can be separated from the pliers head. At this time, the pliers head can be taken out of the pliers handle body, so that the two can be disassembled and separated, thereby realizing the replacement of the pliers handle module. Users can replace the pliers handle modules or pliers heads of different structures according to different needs in different scenarios to achieve different usage functions of the pliers. The same pliers handle module can be applied to pliers heads of various structures, or the same pliers head can be adapted to different pliers handle modules, thereby improving the utilization rate of the pliers handle module or pliers head and reducing the waste of resources to a certain extent, enriching the diversity of tools.
[0007] Furthermore, the rotating shaft assembly includes a pin with a limiting step and a mounting pin, the pin is inserted through the pliers handle body and the pliers head, the mounting pin is located at the end of the pin and is detachably connected to the pin, and the mounting pin also abuts against the pliers handle body. The outer diameter of the pin at the limiting step is smaller than the outer diameter of the pin at other positions, so that the limiting step is similar to the neck of the pin, which facilitates the cooperation between the pin and the locking assembly to achieve the locking of the pin, so that the pliers head and the pliers handle body maintain a connection relationship; the mounting pin is used to install and fix the pin and the pliers handle body, and the mounting pin can also facilitate the installation and removal of the pin.
[0008] Furthermore, the locking assembly includes a locking plate and an operating assembly, the locking plate is installed on the operating assembly, and a first through hole and a second through hole which are interconnected are provided on the locking plate, the aperture of the first through hole is larger than the outer diameter of the upper limit step on the pin, and the aperture of the first through hole is smaller than the outer diameter of the pin, and the aperture of the second through hole is larger than the outer diameter of the pin; the pin is inserted from the second through hole, and the limit step is located at the first through hole or the second through hole, and the operating assembly is partially exposed from the pliers handle body. By arranging a first through hole and a second through hole with different apertures on the locking plate, when the rotating shaft assembly needs to be locked, the pin is located at the limiting step and engaged with the first through hole. At this time, since the outer diameter of the pin is larger than the aperture of the first through hole, the pin can be prevented from passing through the locking plate, thereby enabling the locking assembly to lock the rotating shaft assembly; and when the rotating shaft assembly needs to be unlocked, the operating assembly is used to make the second through hole of the locking plate and the pin located at the limiting step cooperate. At this time, it is a clearance fit. Since the aperture of the second through hole is larger than the outer diameter of the pin, the rotating shaft assembly can be pushed out at this time to separate the pin from the pliers head and the pliers handle body. The pliers head can be disassembled and separated from the pliers handle body to be replaced. Conversely, the pliers head can also be retained and the pliers handle body can be replaced.
[0009] Furthermore, the operating assembly includes a locking plate and a push pin. The locking plate is provided with an installation position, the locking plate is fixedly installed at the installation position, and the push pin is connected to the clamp handle body and is threadedly connected to the locking plate. The locking plate is used to install and fix the locking plate, and at the same time serves as a connection transition between the locking plate and the push pin. The push pin is exposed to the clamp handle body, which is convenient for operation; pushing the push pin causes the push pin to slide relative to the clamp handle body, thereby driving the locking plate to move its position, so that the pin switches from the first through hole to the second through hole, or from the second through hole to the first through hole, which is convenient for the locking assembly to lock or unlock the rotating shaft assembly.
[0010] Furthermore, it also includes a first limiting assembly, which is installed in the body of the clamp handle and is located beside the operating assembly. The first limiting assembly is sleeved outside the pin and can be engaged with the limiting step of the pin. The first limiting assembly is used to limit the rotation shaft assembly. When the rotation shaft assembly is in an unlocked state, the pin is separated from the clamp head. At this time, the pin can always be connected with the clamp handle body to prevent the pin from being separated from the clamp handle body, thereby avoiding the trouble of reinstalling the pin, making it easier to connect the rotation shaft assembly with the clamp head after the clamp head is replaced.
[0011] Furthermore, the first limiting assembly includes a pin spacer and a retaining spring, the retaining spring is mounted on the pin spacer and can be engaged with the limiting step of the pin, and the pin spacer is mounted on the pliers handle body. The provision of the pin spacer can facilitate the installation of the retaining spring, and the engagement of the retaining spring with the pin can achieve limiting of the pin at the extreme position, that is, when the pin is separated from the pliers head.
[0012] Furthermore, it also includes an elastic member, which is located in the body of the pliers handle and sleeved outside the pin, and the elastic member also abuts against the mounting pin. The setting of the elastic member can provide a force to the pin, so that when the locking assembly is in the unlocked state, the elastic force of the elastic member can be used to push the pin to move so that the limit step is engaged with the clamp spring, so that the pin can be limited in the limit state to prevent the pin from being separated from the body of the pliers handle.
[0013] Furthermore, the elastic member is a spring, the mounting pin is a screw, and the mounting pin is threadedly connected to the pin. Within the knowledge of those skilled in the art, the elastic member may also be other structures, and the mounting pin is located at the bottom of the pin. During assembly, the pin is first passed through the pliers handle body, the pliers head, and the locking assembly in sequence, and then the elastic member is sleeved on the bottom of the pin, and then the mounting pin is installed at the bottom of the pin, and the mounting pin and the pin are fastened by threaded connection, so that the pin is fixed in the pliers handle body, and the pliers head can rotate relative to the pliers handle body around the pin.
[0014] The utility model also provides a multifunctional tool pliers, including a pliers head and a detachable pliers handle structure as described above, wherein the pliers head is installed in the pliers handle body, and the rotating shaft assembly is passed through the pliers handle body and the pliers head. The multifunctional tool pliers of the utility model utilizes the detachable connection between the pliers head and the pliers handle body, which can facilitate the connection of the same pliers handle module with different pliers heads, or the same pliers head with different pliers handle modules, which is conducive to improving the applicable occasions of the multifunctional tool pliers and meeting the diverse needs of users, thereby improving the utilization rate of the pliers handle module or the pliers head, and can reduce the waste of resources to a certain extent, enriching the diversity of tools.
[0015] Furthermore, it also includes a second limiting component, the pliers handle body is provided with a limiting groove, the second limiting component is movably installed in the limiting groove and can protrude or hide in the limiting groove; when the pliers head is in use or storage, the second limiting component protrudes out of the limiting groove and abuts against the side of the pliers head; when the pliers head is in the process of rotation, the second limiting member is contracted by the force of the pliers head and hidden in the limiting groove. The setting of the second limiting component can form an obstacle to the pliers head in the open state or the closed state to prevent the pliers head from rotating at will, and in the process of the pliers rotating relative to the pliers handle body, there is resistance only when opening and closing, and in other cases, because the second limiting component falls into the limiting groove, there is almost no resistance to the pliers head, thereby greatly improving the comfort of using the pliers.
[0016] Furthermore, the second limiting assembly includes a spherical limiting bead and a spring, one end of the spring is connected to the limiting bead, and the other end is connected to the bottom of the limiting groove. Preferably, the limiting bead is a steel ball; the spherical limiting bead is located at the side of the pliers head when the pliers head is opened and closed to limit the position, and during the rotation of the pliers head, the limiting bead is compressed and hidden in the limiting groove; within the scope of knowledge of those skilled in the art, the limiting bead includes but is not limited to a spherical structure, and any structure that can meet the above functions can be used.

By providing a first through hole 311 and a second through hole 312 with different apertures on the locking plate 31, when it is necessary to lock the rotating shaft assembly 4, the pin 41 is located at the limiting step 411 and is engaged with the first through hole 311. At this time, since the outer diameter of the pin 41 is larger than the aperture of the first through hole 311, the pin 41 can be prevented from passing through the locking plate 31, thereby enabling the locking assembly 3 to lock the rotating shaft assembly 4; and when it is necessary to unlock the rotating shaft assembly 4, the operating assembly 32 is used to make the second through hole 312 of the locking plate 31 and the pin 41 located at the limiting step 411 cooperate. At this time, it is a clearance fit. Since the aperture of the second through hole 312 is larger than the outer diameter of the pin 41, the rotating shaft assembly 4 can be pushed out at this time to separate the pin 41 from the pliers head 1 and the pliers handle body 2. The pliers head 1 can be disassembled and separated from the pliers handle body 2 to be replaced. Conversely, the pliers head 1 can also be retained and the pliers handle body 2 can be replaced.

The locking spacer 321 is used to install and fix the locking piece 31, and at the same time serves as a connection transition between the locking piece 31 and the push pin 322. The push pin 322 is exposed to the clamp handle body 2, which is convenient for operation; the push pin 322 is pushed to slide relative to the clamp handle body 2, thereby driving the locking piece 31 to move its position, so that the pin 41 switches from the first through hole 311 to the second through hole 312, or switches from the second through hole 312 to the first through hole 311, so that the locking assembly 3 can lock or unlock the rotating shaft assembly 4.

The first limiting assembly 5 is installed in the clamp handle body 2 and is located beside the operating assembly 32. The first limiting assembly 5 is sleeved outside the pin 41 and can be engaged with the limiting step 411 of the pin 41. The first limiting assembly 5 is used to limit the rotation shaft assembly 4. When the rotation shaft assembly 4 is in the unlocked state, the pin 41 is separated from the clamp head 1. At this time, the pin 41 can always be connected with the clamp handle body 2 to prevent the pin 41 from being separated from the clamp handle body 2, thereby avoiding the trouble of reinstalling the pin 41, so that the rotation shaft assembly 4 is easy to connect with the clamp head 1 after the clamp head 1 is replaced.
[0046] Specifically, the first limiting assembly 5 includes a pin spacer 51 and a retaining spring 52.
