[0022] As Figures 1 to 5 shown, a screw feeding mechanism for a screwdriver includes a frame 1. A first sliding component 2 is arranged at the bottom of the inner wall of the frame 1. An elevating support component 3 is arranged above the first sliding component 2. A second sliding component 6 is arranged on the surface of the frame 1. Protective shells 4 are arranged on the top of the elevating support component 3 and the surface of the second sliding component 6. A storage component 5 for placing screws is arranged inside the protective shell 4. More specifically, the storage component 5 can hold screws for users. When in use, the storage component 5 extends out from the inside of the protective shell 4 to avoid confusion when taking screws. When the screws inside one protective shell 4 are used up, the first sliding component 2 drives the elevating support component 3 and the right protective shell 4 to move to the left, and the second sliding component 6 drives the left protective shell 4 to move to the right, so that the protective shell 4 full of bolts reaches the right use position, and screws can be taken continuously. At the same time, the inside of the empty protective shell 4 can be loaded. During the process of the first sliding component 2 driving the elevating support component 3 to move, the elevating support component 3 will control one protective shell 4 to move downward to avoid collision between the two protective shells 4.

[0023] The first sliding component 2 includes a first motor 201, and the first motor 201 is fixedly installed at the bottom of the inner wall of the frame 1. The output end of the first motor 201 is fixedly connected to a first lead screw 202. A mounting plate 203 is threadedly connected to the surface of the first lead screw 202. A first slide bar 204 is fixedly connected to the bottom of the inner wall of the frame 1, and the first slide bar 204 is slidably connected to the mounting plate 203. It should be noted that by operating the first motor 201, the first lead screw 202 is driven to rotate. Under the action of the thread, the mounting plate 203 can be driven to slide along the surface of the first slide bar 204, so as to drive the lifting support component 3 and the protective shell 4 on the right to move.

[0024] The lifting support component 3 includes a slide column 301, and the slide column 301 is fixedly connected to the top surface of the mounting plate 203. A sleeve 302 is movably sleeved on the surface of the slide column 301, and the top end of the sleeve 302 is fixedly connected to the bottom surface of the protective shell 4. A connecting plate 303 is fixedly connected to the bottom of the right protective shell 4. A guide wheel 304 is rotatably connected to the surface of the connecting plate 303. A guide groove 305 is formed through the surface of the frame 1, and the inner wall of the guide groove 305 is rotatably connected to the guide wheel 304. More specifically, when the mounting plate 203 moves, it will drive the slide column 301, the sleeve 302 and the protective shell 4 to move. The protective shell 4 will drive the connecting plate 303 to move, thereby driving the guide wheel 304 to slide along the inner wall of the guide groove 305. Under the action of the guide groove 305, the guide wheel 304, the connecting plate 303 and the protective shell 4 will be pulled up and down, and then the sleeve 302 will be driven to slide along the surface of the slide column 301. When the guide wheel 304 moves to the middle of the guide groove 305, the right protective shell 4 will drop below the left protective shell 4, so that the two protective shells 4 will not collide.

[0025] The storage component 5 includes a storage box 501, and the storage box 501 is slidably connected to the inner wall of the protective shell 4. A placement hole 502 is formed through the top surface of the storage box 501. A second motor 503 is fixedly installed on the left side surface of the protective shell 4. The output end of the second motor 503 is fixedly connected to a second lead screw 504, and the second lead screw 504 is threadedly connected to the storage box 501. A second slide bar 505 is fixedly connected to the inner wall of the protective shell 4, and the surface of the second slide bar 505 is slidably connected to the storage box 501. It should be noted that the screws can be placed inside the placement hole 502, so as to place the screws neatly and conveniently for taking. By operating the second motor 503, the second lead screw 504 is driven to rotate, thereby driving the storage box 501 to slide along the surface of the second slide bar 505, so that the storage box 501 extends out of the protective shell 4, and a placement hole 502 is exposed outside the protective shell 4. Then the screws can be taken from the placement hole 502. Next time when taking, the second motor 503 continues to control the movement of the storage box 501, so that two placement holes 502 are exposed outside the protective shell 4, and the screws can be taken again, thus ensuring that the order of taking screws will not be chaotic.

[0026] The second sliding assembly 6 includes a third motor 601, and the third motor 601 is fixedly installed on the front of the frame 1. The output end of the third motor 601 is fixedly connected to the third screw rod 602, and the surface of the third screw rod 602 is threadedly connected to the connecting rod 603, and the end of the connecting rod 603 is fixedly connected to the left protective shell 4, and the back of the left protective shell 4 is fixedly connected to the clamping block 604, and the clamping block 604 is slidably connected to the surface of the frame 1. More specifically, the third motor 601 is operated to drive the third screw rod 602 to rotate, and the connecting rod 603 is driven to move under the action of the thread, thereby pulling the protective shell 4 on the left to move. During the movement of the protective shell 4, the clamping block 604 will be driven to slide along the top of the frame 1, and the protective shell 4 is limited by the clamping block 604, so that the protective shell 4 remains stable.

[0027] The number of storage components 5 is multiple groups, and the multiple groups of storage components 5 are arranged at equal intervals inside the protective shell 4. It should be noted that by providing multiple groups of storage components 5, it is convenient to arrange the screws regularly, which is convenient for subsequent retrieval and not easy to cause confusion.

[0028] In summary: the storage component 5 can be used to hold screws for user use. When needed, the storage component 5 extends from the inside of the protective shell 4 to avoid confusion when taking the screws. When the screws inside a protective shell 4 are used up, the first sliding component 2 drives the lifting support component 3 and the right protective shell 4 to move to the left, and the second sliding component 6 drives the left protective shell 4 to move to the right, so that the protective shell 4 fully loaded with bolts reaches the right use position, and the screws can continue to be taken, and the inside of the unloaded protective shell 4 can be loaded at the same time. In the process of the first sliding component 2 driving the lifting support component 3 to move, the lifting support component 3 will control a protective shell 4 to move downward to avoid conflict between the two protective shells 4, thereby achieving the effect of facilitating the use of screws during use. After the screws are taken, the screws can be quickly loaded without stopping and waiting, thereby avoiding affecting the processing efficiency.
