DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3In this embodiment, a disposable T-shaped tool that is easy to install includes a handle 1, a cutter head handle 2 is fixedly connected to the lower end of the handle 1, a cutter head 3 is fixedly connected to the lower end of the cutter head handle 2, a mounting block 4 is movably connected to the upper end of the handle 1, and a disassembly structure 5 is provided at the connection between the mounting block 4 and the handle 1.

[0022] The disassembly and assembly structure 5 includes a fixed block 501, a telescopic spring 502, a telescopic rod 503, a limiting rod 504, a fixed frame 505, a handle 506, a limiting rod 507, a clamping block 509, and a threaded rod 508. The fixed block 501 is fixedly connected to the inner wall of the knife handle 1, one end of the telescopic rod 503 is fixedly connected to the outside of the fixed block 501, the telescopic spring 502 is sleeved on the outside of the telescopic rod 503 located inside the knife handle 1, the limiting rod 504 is fixedly connected to the other end of the telescopic rod 503, the fixed frame 505 is fixedly connected to the side of the mounting block 4, the threaded rod 508 is threadedly connected to the fixed frame 505, the handle 506 is fixedly connected to one end of the threaded rod 508, the clamping block 509 is fixedly connected to the other end of the threaded rod 508, and the limiting rod 507 is fixedly connected to the handle 506.

[0023] One end of the telescopic spring 502 is fixedly connected to the fixed block 501 , and the other end of the telescopic spring 502 is fixedly connected to the inside of the knife handle 1 .

[0024] It should be noted that a movable hole is provided on the outer side of the knife handle 1 , and the telescopic rod 503 passes through the knife handle 1 through the movable hole.

[0025] It can be understood that the telescopic spring 502, commonly known as a spring coil or elastic coil, is an elastic element widely used in engineering and daily life. Its main function is to deform when subjected to external force and to return to its original shape after the external force is removed. The telescopic spring 502 plays an important role in many mechanical and electronic equipment, such as automobile suspension systems, fitness equipment, watches, etc.

[0026] The telescopic spring 502 is usually wound from a metal wire and can be round, square or rectangular in cross section, or in special shapes such as diamond or triangle to suit different application requirements. Depending on factors such as the wire diameter, number of turns, working diameter and preload of the spring, the telescopic spring 502 can withstand forces of different magnitudes and have different elastic properties.

[0027] The elastic properties of the telescopic spring 502 can be adjusted by controlling its material, diameter, wire diameter, number of turns, heat treatment process, etc. Among them, the material is a key factor affecting the spring performance, and common materials include carbon steel, stainless steel, copper, etc.

[0028] The service life and performance stability of telescopic spring 502 are closely related to its quality. When purchasing telescopic spring 502, you should pay attention to choosing springs produced by regular manufacturers and in line with national or industry standards, and ensure that they do not exceed their tolerance range during use to ensure their performance and life.

[0029] In this embodiment, a mounting plate is fixedly connected to the outer side of the mounting block 4, and a mounting hole is opened inside the mounting plate.

[0030] The mounting block 4 is mounted on the device through the mounting plate and the mounting hole.

[0031] In this embodiment, a thread groove is provided in the fixing frame 505 , and the threaded rod 508 is threadedly connected to the fixing frame 505 through the thread groove.

[0032] In this embodiment, a limiting hole is opened in the fixing frame 505 near the thread groove, and the limiting rod 507 passes through the fixing frame 505 through the limiting hole.

[0033] In this embodiment, a slot is defined in the limiting rod 504 , and the blocking block 509 abuts against the limiting rod 504 through the slot.

[0034] In this embodiment, a through hole is formed at the lower end of the mounting block 4, and the knife handle 1 passes through the mounting block 4 through the through hole.

[0035] In this embodiment, a limiting hole is provided on the side of the mounting block 4 , and the limiting rod 504 passes through the limiting hole and penetrates the mounting block 4 .

[0036] Among them, the structures in the disassembly and assembly structure 5 are all distributed in a symmetrical structure based on the installation block 4.

[0037] It should be noted that when the T-shaped tool needs to be discarded, the handle 506 is turned to drive the threaded rod 508 to rotate, and the threaded rod 508 is limited by the limit rod 507 during rotation. After the threaded rod 508 is displaced, the blocking block 509 can be separated from the limit rod 504. At this time, the limit rod 504 is pressed, and the limit rod 504 can cooperate with the telescopic spring 502 and the telescopic rod 503 to retract. The T-shaped tool is disassembled by taking the tool handle 1 to separate it from the mounting block 4, thereby enhancing the installation efficiency of the T-shaped tool and the equipment.

[0038] The working principle of the above embodiment is:

[0039] First, by installing the mounting block 4 on the device.

[0040] Secondly, by pressing the limit rod 504, the limit rod 504 can cooperate with the telescopic spring 502 and the telescopic rod 503 to retract and retract, and the T-shaped tool is placed in the mounting block 4 by taking the tool handle 1. At this time, the limit block 504 is loosened, and after the limit block 504 is plugged into the two sides of the mounting block 4, the threaded rod 508 is driven to rotate by turning the handle 506, and the threaded rod 508 is limited by the limit rod 507 during rotation. After the threaded rod 508 is displaced, it can drive the blocking block 509 to contact the limit rod 504, thereby completing the flexible installation of the T-shaped tool in the mounting block 4.

[0041] Finally, when the T-shaped tool needs to be discarded, the handle 506 is turned to drive the threaded rod 508 to rotate, and the threaded rod 508 is limited by the limit rod 507 during rotation. The displacement of the threaded rod 508 can drive the block 509 to separate from the limit rod 504. At this time, by pressing the limit rod 504, the limit rod 504 can cooperate with the telescopic spring 502 and the telescopic rod 503 to retract. The T-shaped tool is disassembled by taking the tool handle 1 to separate it from the mounting block 4, thereby enhancing the installation efficiency of the T-shaped tool and the equipment.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
