Description

Technical Field

[0001] The utility model relates to the technical field of blade structures, and particularly relates to a multi-functional putty knife tool with replaceable blades. Background Art

[0002] A putty knife, also known as a spatula, is classified as a paint auxiliary tool. It is simple and convenient to use and can be used in various ways such as scraping, shoveling, applying, and filling. It is widely used in the field of construction and daily life.

[0003] Currently, the structure of the bit of the existing putty knife with a bit usually includes a bit, which is fixed to the bottom of the putty knife handle; the connection structure between the putty knife handle and the blade is usually that the putty knife handle has a mounting groove that restricts the movement of the blade, and generally a limiting post is provided at the tail of the blade, and the limiting post can be a rectangular parallelepiped limiting post.

[0004] The existing putty knives generally adopt a structure in which the blade body and the handle are fixedly connected. Since putty knives of different widths need to be used in different construction situations, users must carry multiple putty knives with them when working, which is not only troublesome to carry but also increases the usage cost.

[0005] There is a need for a putty knife tool handle that can conveniently replace the blade to solve the above problems. Summary of the Utility Model

[0006] The utility model provides a multi-functional putty knife tool with replaceable blades. By technically modifying the existing spatula tool, the problem that the existing putty knife cannot conveniently and quickly replace the blade is solved.

[0007] To achieve the above object, the technical solution adopted by the utility model is:

[0008] A multi-functional putty knife tool with replaceable blades includes a handle part, a locking component, and a blade part. The handle part is assembled by an upper shell and a lower shell. An installation slot opening for inserting the blade part is provided at the upper end of the handle part, and a locking component for installing and disassembling the blade part is installed between the upper shell and the lower shell. The blade part passes through the installation slot opening and is engaged with the locking component.

[0009] Preferably, slope surfaces are provided on the left and right sides at the lower end of the blade part, and the lower edge of the slope surface abuts against the upper edge of the installation slot opening.

[0010] Preferably, the lock assembly includes a control button, an elastic member, and a rotating shaft. The control button is divided into a pressing portion, a rotating portion, and a locking portion. A through hole is formed in the rotating portion. The rotating shaft is movably installed inside the handle portion through the through hole of the rotating portion of the control button. The two sides of the rotating portion are respectively connected to the pressing portion and the locking portion. The pressing portion extends out of the handle portion and is exposed. The locking portion is arranged inside the handle portion. The locking portion is in contact with the inner side surface of the handle portion through the elastic member. A fixed card slot is formed in the locking portion. A buckle portion is arranged at the lower end of the blade portion. The buckle portion and the fixed card slot are mutually engaged.

[0011] Preferably, an arc-shaped pressing groove is arranged on the outer side surface of the handle portion where the pressing portion is exposed.

[0012] Preferably, the elastic member is a spring. A spring installation groove is formed on one side of the locking portion facing the inner side wall of the handle portion. The spring is installed in the spring installation groove, and the other end of the spring away from the locking portion is in contact with the inner side wall of the handle portion.

[0013] Preferably, the buckle portion includes a first recessed portion and a second protruding portion. The lower end of the blade portion is recessed inward to form a first recessed portion. The lower end of the first recessed portion extends outward to the left and right to form a second protruding portion. The second protruding portion is in contact with the lower end surface of the locking portion of the control button.

[0014] Preferably, there are two control buttons, which are installed on the left and right sides of the handle portion respectively. The blade portion is clamped and fixed between the two control buttons.

[0015] Preferably, an installation notch is arranged at the upper end position of the handle portion. A lock installation slot is arranged below the installation notch. The lock assembly is installed at the lock installation slot. An opening for the button is arranged on the outer side surface of the lock installation slot. The pressing portion passes through the opening for the button and extends out. A holding portion is arranged at the lower end of the handle portion.

[0016] Preferably, anti-slip patterns are arranged on the outer surface of the holding portion.

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

[0018] In the present utility model, a movable control button is installed inside the handle portion. One end of the control button is in contact with the inner side surface of the handle portion through a spring. A buckle portion is arranged at the lower end of the blade portion. When the blade portion is inserted into the handle portion, the buckle portion and the fixed card slot formed in the control button are mutually engaged. When the blade portion is pulled upward, the blade portion is limited by the control button and cannot be easily separated, so that the blade portion can be fixed on the handle portion.

[0019] When the blade part needs to be switched, by pressing the control buttons on both sides of the handle part, the control buttons rotate relative to the handle part, the locking part separates to both sides, and the blade part is released, so that the blade part can be detached from the installation notch of the handle part.
