In addition, the forms of the respective structures described in the following embodiments are merely examples, and a drop-proof electric screwdriver bit related to the present utility model is not limited to the respective structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0024] Refer to Figures 1 to 5, the present utility model provides a fall-proof electric screwdriver bit, including a bit head 1, and further including: a fixing device 2, a body 3, a machine column 4, and a base 5. The side surface of the bit head 1 is fixedly connected to the inside of the fixing device 2. One end of the fixing device 2 is fixedly connected to one end of the body 3. The side surface of the body 3 is fixedly connected to the top end of the machine column 4. The bottom end of the machine column 4 is fixedly connected to the top end of the base 5. The bit head 1 includes a Phillips bit 101 and a bit sleeve 102. The side surface of the Phillips bit 101 is fixedly connected to the inside of the bit sleeve 102, increasing the sectional thickness of the Phillips bit 101, making the Phillips bit 101 have a thick and short structure, which is beneficial to increasing the anti-fall property and stability of the Phillips bit 101. The fixing device 2 includes a self-locking buckle 201 and a chuck 202. One end of the self-locking buckle 201 is fixedly connected to one end of the chuck 202. Among them, a hole is provided on the side surface of the self-locking buckle 201, and the inside of the self-locking buckle 201 is fixedly connected to the side surface of a steel ball 203. After the Phillips bit 101 is inserted into the chuck 202, it is assisted by the self-locking buckle 201 for fixation, strengthening the firmness of the connection between the Phillips bit 101 and the chuck 202, making the connection between the Phillips bit 101 and the chuck 202 tighter and not easily separated from the chuck 202 when being impacted. There are vertical stripes on the side surface of the chuck 202. The body 3 includes a rubber pad 301, a machine wall 302, and a rear cover 303. The side surface of the rubber pad 301 is fixedly connected to the side surface of the machine wall 302. The rubber material can reduce the impact of vibration on the internal mechanical components and improve the anti-fall performance. There is a thread on one end side surface of the machine wall 302, and one end of the machine wall 302 is fixedly connected to the rear cover 303 through the thread. The machine column 4 includes a switch 401 and a handle 402. The side surface of the switch 401 is fixedly connected to the side surface of the handle 402. The bottom end of the handle 402 is fixedly connected to the top end of the base 5.
[0025] Among them, a hexagonal head 103 is fixedly connected to one end of the Phillips bit 101, and the hexagonal shape of the hexagonal head 103 fits the internal opening of the chuck 202.
[0026] Among them, a storage groove 304 is provided at one end of the machine wall 302. The opening of the storage groove 304 is hexagonal, which fits the bit shape. It can effectively reduce the small-distance friction during storage. When the device is not in use, the bit can be placed in the storage groove 304, which is beneficial to the daily maintenance of the bit.
[0027] Among them, a layer of rubber material covers the side surface of the handle 402, increasing the friction force and reducing the probability of the device slipping out of the hand.
[0028] Among them, the base 5 is overall in the shape of a quadrangular frustum. The internal loading of the device battery makes the overall structure center of gravity of the device lower, which is beneficial to the overall stability of the device.
[0029] Working principle of the utility model: When using this device, the user first opens the rear cover 303 fixedly connected to the machine wall 302 through threads, takes out the required bit. Taking the cross bit 101 as an example, one end of the cross bit 101 is fixedly connected to one end of the hexagonal head 103. The hexagonal shape of the hexagonal head 103 fits the internal opening of the chuck 202. One end of the chuck 202 is fixedly connected to one end of the self-locking buckle 201. Insert the hexagonal head 103 into the chuck 202, fixedly connect the inside of the bit sleeve 102 to the side of the cross bit 101, turn on the switch 401, and then this device can be used. After use, remove the bit sleeve 102 from the cross bit 101, put the cross bit 101 back into the storage groove 304, and screw on the rear cover 303, which can effectively store and protect the bit. The side of the machine wall 302 is fixedly connected to the side of the rubber pad 301. The rubber material can reduce the impact of vibration on the internal mechanical components and improve the anti-drop performance. When the device accidentally slips out of the hand and falls, it can effectively protect the body. The side of the handle 402 is covered with a layer of rubber material, which can increase the friction force and reduce the probability of the device slipping out of the hand. The base 5 is generally in the shape of a quadrangular frustum, and the device battery is loaded inside, making the overall center of gravity of the device lower, which is beneficial to the overall stability of the device.
[0030] The above are only the preferred embodiments of the utility model, and are not used to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
