Description

Technical Field

[0001] This utility model relates to the field of hollow handle knife technology, and in particular to a hollow handle knife that is easy to adjust the length of the handle. Background Technology

[0002] In practical applications of knives, whether in industrial production, outdoor work, or daily life, the requirements for handle length and blade replacement are diverse. Hollow handle knives refer to knives with a hollow handle design. This design is usually to reduce the weight of the knife and make it easier to carry and use.

[0003] Existing hollow shank knives have the following disadvantages:

[0004] Traditional hollow-handled knives typically have a fixed handle length, which cannot meet the grip needs of users in different operating environments. When working in confined spaces, an excessively long handle can lead to inconvenience in operation; while in cutting work that requires greater force, an excessively short handle cannot provide a good grip and force application.

[0005] Traditional knives are prone to loosening during use, affecting safety and work efficiency. Furthermore, replacing the blade often requires specialized tools, making disassembly and installation complex. On the other hand, the anti-slip treatment on the handle surface is limited and cannot simultaneously meet the dual requirements of anti-slip and anti-stick. In humid or oily environments, slippage can easily occur, severely impacting the user experience and safety. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hollow handle knife that facilitates adjustment of the handle length.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A hollow handle knife with adjustable handle length includes a connecting frame, on which a length adjustment mechanism and a detachable mounting mechanism are installed;

[0009] The length adjustment mechanism includes a connecting plate, a fixed sleeve, a first adjusting rod, a sliding groove, a second adjusting rod, a threaded connecting sleeve, and a connecting rod. One end of the fixed sleeve is movably connected to the inner wall of one side of the connecting plate. One end of the first adjusting rod is sleeved inside the fixed sleeve. A sliding groove is provided on one side of the first adjusting rod. A sliding strip is welded inside the second adjusting rod. The other end of the first adjusting rod is slidably engaged with the inner wall of one end of the second adjusting rod through the sliding strip. The other end of the second adjusting rod is sleeved to the inner wall of one end of the threaded connecting sleeve. One end of the connecting rod is screwed to the inner wall of the other end of the threaded connecting sleeve.

[0010] With the above solution, the length adjustment mechanism is installed. The first adjustment rod and the second adjustment rod are slidably engaged through a sliding bar and a sliding groove. The second adjustment rod is connected to the threaded connecting sleeve and the connecting rod through a thread. This combination method is not only easy to operate, requiring only simple sliding and rotating actions to complete the adjustment, but also can remain stable after adjustment to avoid loosening, greatly improving the adaptability of the tool in different usage scenarios.

[0011] Preferably, the detachable installation mechanism includes a movable slot, a fixed plate, a fixed rod, a positioning strip, a protective plate, and a blade. The inner wall of one side of the fixed plate is provided with an installation slot. The two ends of the fixed rod are respectively sleeved with the inner sides of the two fixed plates. The two positioning strips are inserted into the inner walls of both sides of the fixed plate. The outer wall of one end of the fixed rod is connected to one side surface of the positioning strip.

[0012] With the above solution, a detachable mounting mechanism is installed. The fixing plate, fixing rod, positioning strip and other components work together to allow the knife body to be installed and removed with a simple plug-and-play operation. No additional tools are needed, saving replacement time and improving work efficiency. It also facilitates the maintenance of the knife and the replacement of different knife bodies. The anti-slip component design not only effectively prevents water stains, oil stains and other dirt from adhering, but also further enhances the anti-slip effect, allowing the knife handle to maintain a stable grip in various complex environments, improving the safety and reliability of use.

[0013] Preferably, the protective plate is snapped onto the top surface of the connecting frame, one end of the blade body has a connecting hole, the fixing rod is inserted into the inside of the connecting hole, and the blade body is tightly connected to one side inner wall of the connecting frame through the fixing rod.

[0014] Preferably, the other side surface of the connecting plate is fixedly connected to one side outer wall of the connecting frame, and anti-slip components are installed on the surfaces of the second adjusting rod and the connecting rod.

[0015] Preferably, the anti-slip component includes a first anti-slip layer and a second anti-slip layer. The first anti-slip layer covers one outer wall of the second anti-slip layer, and the second anti-slip layer is sleeved with the surface of the connecting rod. The surface of the first anti-slip layer is coated with nano-silica material, and the second anti-slip layer is made of thermoplastic elastomer material.

[0016] Preferably, both sides of the connecting frame are provided with movable slots, and the fixed plate is engaged with the outer wall of the movable slot.

[0017] The beneficial effects of this utility model are as follows:

[0018] By installing a length adjustment mechanism, the first adjustment rod and the second adjustment rod are slidably engaged through a sliding bar and a sliding groove. The second adjustment rod is connected to the threaded connecting sleeve and the connecting rod through a thread. This combination method is not only easy to operate, requiring only simple sliding and rotating actions to complete the adjustment, but also can remain stable after adjustment to avoid loosening, greatly improving the adaptability of the tool in different usage scenarios.

[0019] With the installation of a detachable mounting mechanism, components such as the fixing plate, fixing rod, and positioning strip work together to allow for easy installation and removal of the knife body through simple plugging and unplugging operations. No additional tools are needed, saving replacement time and improving work efficiency. It also facilitates knife maintenance and the replacement of different knife bodies. The anti-slip component design not only effectively prevents water stains and oil stains from adhering, but also further enhances the anti-slip effect, allowing the knife handle to maintain a stable grip in various complex environments, thus improving the safety and reliability of use.
