[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-4 A tool holder for easy steering and positioning includes a horizontally arranged tool handle 1 and a blade 3. The lower end of the tool handle 1 and near the left edge are provided with a storage groove. A vertically arranged storage plate 2 is rotatably connected to the inner wall of the storage groove to support the blade 3. The lower end of the storage plate 2 passes through the storage groove. The surface of the storage plate 2 is provided with a placement groove that matches the shape of the blade 3. The blade 3 is placed in the placement groove, and the blade tip of the blade 3 passes through the placement groove. The surface of the blade 3 is provided with a first locking screw 4 to fix the blade 3. The blade 3 is fixed to the storage plate 2 by the first locking screw 4.
[0023] In this embodiment, a pressure block 5 is slidably connected to the inner wall of the storage slot to press the storage tray 2. The pressure block 5 is located at the upper end of the storage tray 2. A locking block 11 is fixedly connected to the lower end of the pressure block 5 to lock the position of the storage tray 2 in conjunction with the locking slot. Multiple locking slots corresponding to the locking block 11 are provided on the outer wall of the storage tray 2. The lower end of the locking block 11 slides into the locking slot. A vertically arranged guide rod 9 is slidably inserted into the inner top of the storage slot to guide the movement of the pressure block 5. The lower end of the guide rod 9 is fixedly connected to the upper end of the pressure block 5. A fixing ring 10 is fixedly sleeved on the lower end of the guide rod 9 to improve the firmness between the guide rod 9 and the pressure block 5. The lower end of the fixing ring 10 is fixedly connected to the upper end of the pressure block 5.
[0024] In this embodiment, the upper end of the pressure block 5 is rotatably connected to a lead screw 7, which is used to drive the pressure block 5 to move. The lower end of the lead screw 7 is rotatably sleeved with a connecting ring 8, which is used to improve the firmness between the lead screw 7 and the pressure block 5. The lower end of the connecting ring 8 is fixedly connected to the upper end of the pressure block 5. The upper end of the lead screw 7 passes through the knife handle 1 and is fixedly connected to a knob 6, which is used to drive the lead screw 7 to rotate. The lead screw 7 and the knife handle 1 are connected by a thread.
[0025] In this embodiment, a second locking screw 13 is inserted at the upper end of the knob 6 near the edge to cooperate with the locking groove to prevent the knob 6 from loosening. The lower end of the second locking screw 13 passes through the knob 6, and the second locking screw 13 and the knob 6 are connected by threads. The upper side wall of the handle 1 has a plurality of locking grooves corresponding to the second locking screw 13 arranged in a ring. The upper end of the knob 6 is provided with an internal hexagonal groove 12 to facilitate the user to rotate the knob 6 with an internal hexagonal wrench.
[0026] In this embodiment, firstly, the first locking screw 4 is tightened to secure the blade 3 to the tray 2. Then, the knob 6 is manually turned to drive the lead screw 7 to rotate. The lead screw 7 moves up and down within the handle 1 by means of the thread engagement principle (rotating the knob 6 forward raises the blade, and rotating it backward lowers the blade). When the lead screw 7 rises, it drives the pressure block 5 and the locking block 11 to move upward synchronously, causing the locking block 11 to disengage from the slot. At this time, the tray 2 can be manually rotated to adjust the angle of the blade 3. When the lead screw 7 descends, the pressure block 5 presses against the tray 2, and the locking block 11 falls into the slot, thereby locking the tray 2 and preventing the blade 3 from loosening.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
