AI Technical Summary
The existing electric shaver's body and head connection structure is prone to wear and tear, leading to unstable installation. Furthermore, it is difficult to find a suitable magnetic attraction strength for the magnetic connection method to ensure stability and ease of use.
The limiting mechanism is a spherical structure consisting of a spring and a top pressure terminal. The machine body and the cutter head are connected by a plug and a socket. The elastic clamping of the limiting mechanism is used to achieve stable assembly. Combined with the design of the water-proof pad and the support plate, it ensures smooth and stable insertion and removal.
This achieves stable assembly between the machine body and the cutting head, avoiding the problem of unstable clamping caused by wear, improving insertion and removal life and ease of use, while simplifying the processing and use process.

TECHNICAL FIELD
[0001] The present application relates to the technical field of electric shavers, in particular to the technical field of shaver heads that are pluggable. BACKGROUND
[0002] Shavers can be divided into manual shavers and electric shavers according to the driving mode. The electric shaver generally includes a body, a shaver head mounted on the top of the body, a battery pack mounted in the body, a driving mechanism and a circuit board, and a button group mounted on the outer wall of the body. In use, the shaver head is driven to move by electricity, and then the beard is shaved by the blade fixed on the shaver head. With the continuous improvement of people's living standards, people have increasingly high requirements for the multifunctionality of electric shavers. In order to meet this market demand, more and more manufacturers choose to set the body and the shaver head as detachable connection, so that the body can be used in cooperation with shaver heads with different functions, such as shaving heads, temple heads, nose hair heads, cleaning brushes, hair cutting heads and limiting combs, etc.
[0003] For shavers with multiple functions, since the body and the shaver head are separable, the plug-in connection structure between the body and the shaver head is particularly important. At present, most manufacturers choose to use the concave-convex cooperation between the traditional groove and the protrusion to realize the detachable connection between the body and the shaver head, such as the shaver disclosed in the patent with the publication number CN106584526B and the shaver with detachable shaver head disclosed in the utility model patent with the publication number CN208729851U. However, since the bodies and the shaver heads of shavers on the market are basically made of plastic, the protrusions made of plastic material are prone to serious wear after long-term plugging, which may cause unstable installation of the shaver head.
[0004] In addition, some manufacturers choose to use magnetic attraction to realize the detachable connection between the body and the shaver head, such as the detachable connection structure of the shaver head of the electric shaver disclosed in the utility model patent with the publication number CN217992574U. However, if the magnetic attraction is too strong, it will be difficult to replace the shaver head, and if the magnetic attraction is too weak, it will cause the shaver head to be loose and unstable, which is difficult and troublesome to produce.
