[0030] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0031] See also Figure 1-Figure 6 The utility model discloses a hidden screw type tool comprising: a tool handle 1, a plurality of first screws 2 and a blade 3. The tool handle 1 is connected to the blade 3.

[0032] The knife handle 1 includes an inner shell structure 11 and an outer shell structure 12. The inner shell structure 11 includes a connecting member 111 and at least two inner shell plates 112. The two inner shell plates 112 are arranged oppositely and spaced apart, and are connected by the connecting member 111, so that a spacing groove 113 is formed between the two inner shell plates 112. The inner shell plate 112 is provided with a through hole 1121; the outer shell structure 12 includes at least two outer shell plates 121, the two outer shell plates 121 are arranged oppositely and spaced apart, and the two inner shell plates 112 are sandwiched by the two outer shell plates 121. The outer shell plate 121 is provided with a blind hole 1211. The direction in which the spacing groove 113 points to the outer shell plate 121 is defined as the installation direction. It can be understood that there are two installation directions, which extend in directions away from the spacing groove 113 respectively.

[0033] Importantly, the first screws 2 are sequentially inserted into the through holes 1121 and the blind holes 1211 along the installation direction to fix the inner shell 112 and the outer shell 121 together.

[0034] During installation, first insert the first screw 2 into the spacing groove 113, and then sequentially drive the first screw 2 into the inner shell plate 112 and the outer shell plate 121 along the installation direction, so that the two outer shell plates 121 are respectively fixed to one of the inner shell plates 112. The inner shell structure 11 can be an integrated molding structure, that is, the connecting member 111 and the two inner shell plates 112 are integrally injection molded; of course, the inner shell structure 11 can also be a split structure, which will be described in detail below.

[0035] Obviously, the inner shell structure 11 and the outer shell structure 12 are fixed by the first screw 2, and the first screw 2 is hidden in the area where the spacing groove 113 is located, and the first screw 2 is protected by the through hole 1121 and the blind hole 1211, so it is not easy to get wet or bumped, so that the first screw 2 is not easy to rust and corrode, and is not easy to loosen. It should be noted that by forming the spacing groove 113 with the help of the inner shell structure 11, the first screw 2 can be installed along the installation direction, which provides a prerequisite for the concealed installation of the first screw 2.

[0036] In this embodiment, in order to facilitate installation of various spare parts in the spacing groove 113, it is important that the inner shell structure 11 further includes one or more second screws 114, and the second screws 114 are sequentially inserted through one of the inner shell plates 112, the connecting member 111 and the other inner shell plate 112. In other words, the inner shell structure 11 is a split structure, and one of the inner shell plates 112 and the other inner shell plate 112 are fixed together by the second screws 114. In this way, it is convenient to install accessories such as the blade 3 and the rotating shaft 6 on the inner shell structure 11.

[0037] In this embodiment, preferably, the blade 3 is movably connected to the handle 1 (e.g., pivotally connected), and can be rotated relative to the handle 1 to switch between a storage state in the spacing groove 113 and a use state outside the spacing groove 113. In this way, the present hidden screw-type tool is a retractable tool, that is, the blade 3 can be stored in the spacing groove 113, so that it occupies a smaller storage space and transportation space.

[0038] In this embodiment, in order to prevent the blade 3 from retracting when in use, and to prevent the blade 3 from automatically rotating out when in storage, preferably, one of the inner shell plate 112 and the blade 3 is provided with a marble structure, and the other is provided with a marble hole. At least one of the marble structure and the marble hole is provided with a plurality of marbles; the marble structure includes a reset elastic member and a locking marble abutting against the reset elastic member, and the locking marble can cooperate with the marble hole to lock the blade 3. The elastic reset member is a spring or a rubber pad. Preferably, both the marble hole and the marble structure are provided with a plurality of marbles, and the plurality of marble holes are arranged at intervals around the axis of the rotating shaft 6.

[0039] In this embodiment, see Figure 5 Preferably, the handle 1 is connected with a rotation stroke limiter 4, and the blade 3 has an opening rear stroke limiter 31 and a closing rear stroke limiter 32. When the blade 3 is in the storage state, the closing rear stroke limiter 32 is abutted and limited by the rotation stroke limiter 4; when the blade 3 is in the use state, the opening rear stroke limiter 31 is abutted and limited by the rotation stroke limiter 4. In this way, the rotation stroke of the blade 3 is absolutely limited by the rotation stroke limiter 4 to prevent the blade 3 from scratching the hand. Specifically, the rotation stroke limiter 4 is a rod-shaped structure, the opening rear stroke limiter 31 is a groove structure, and the closing rear stroke limiter 32 is a groove structure; in this way, the rod-shaped structure is adapted to the groove structure, and the matching tightness is better. It can be understood that as an alternative setting method, the rotation stroke limiter 4 can be a first protrusion structure, the opening rear stroke limiter 31 can be a second protrusion, and the closing rear stroke limiter 32 can be a third protrusion, etc.

[0040] In this embodiment, in order to make the blade 3 rotate more smoothly, preferably, the handle 1 is connected to a bearing 5, the bearing 5 is connected to a rotating shaft 6, and the blade 3 is movably or fixedly sleeved on the rotating shaft 6. It can be understood that as an alternative arrangement, the blade 3 and the handle 1 can be braked by a damping force. In this arrangement, the blade 3 can also be prevented from rotating freely without adding a marble structure and a marble hole.

[0041] In this embodiment, in order to absolutely prevent the blade 3 from scratching a person's hand, preferably, when the blade 3 is in the storage state, the cutting edge of the blade 3 is arranged opposite to the connecting member 111 .

[0042] In this embodiment, preferably, the blind hole 1211 is a screw hole, so that the first screw 2 can be reliably fixed to the handle 1. It can be understood that, as an alternative arrangement, the first screw 2 can refer to two assembly methods of a bayonet bulb and a threaded head bulb, that is, the screw can be a screw, or a light rod with a straight-shaped limit strip (that is, two convex points equivalent to the bayonet bulb to match the bayonet), etc.

[0043] In this embodiment, in order to facilitate carrying a hidden screw-type tool, preferably, the outer shell plate 121 is connected to a trouser pocket clamp rod 7, and the trouser pocket clamp rod 7 is spaced apart from the outer shell plate 121 to form a clamping accommodating groove 8, the clamping accommodating groove 8 is used to accommodate the trouser pocket edge, and the trouser pocket clamp rod 7 is used to be inserted into the trouser pocket.
