Description

Technical Field

[0001] This utility model relates to the field of screwdriver head technology, and in particular to a novel three-lobed screwdriver head. Background Technology

[0002] A screwdriver head is a tool tip used to tighten or loosen screws. It is also called a "screwdriver bit" or "screwdriver tip". It is the core actuating component of a screwdriver and directly contacts the screw to transmit torque.

[0003] Existing screwdriver heads are usually sleeve type. After the screw feeder dispenses the screw, the screw falls into the positioning sleeve in a free-fall manner through the sleeve type head. The screwdriver bit rotates to lock the screw into the product. However, when the screw falls into the positioning sleeve, the screw will be skewed to a certain extent. The screw is not locked into the product vertically, which will result in poor screw torque or the screw not being locked in place even when the torque is reached. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of three-lobed screwdriver head, which solves the problem that when the screw falls into the positioning sleeve of the existing sleeve-type screwdriver head, the screw will be skewed to a certain extent, and the screw will not be driven into the product vertically, which will lead to poor screw torque or the screw not being locked in place when the torque is reached.

[0005] To achieve the above objectives, a novel three-part nozzle screwdriver head is provided, comprising: a sleeve, a three-part nozzle fixedly connected to the bottom of the sleeve, a feeder connected to the top of the sleeve, and a vacuum suction device provided on one side of the top of the sleeve, which is connected to the screwdriver bit, thereby preventing screw misalignment, facilitating vertical screw insertion into the product, and reducing the occurrence of screw torque defects.

[0006] According to the novel three-lobed screwdriver bit, the bottom end of the bit is provided with an adsorption hole, and the bottom end of the bit is used to adsorb screws through the adsorption hole and a vacuum suction device, which facilitates the adsorption of screws.

[0007] According to the novel three-lobed screwdriver head, the outer wall of the three-lobed screwdriver head is provided with a mounting groove, and a reset ring is movably connected inside the mounting groove to facilitate the reset of the three-lobed screwdriver head.

[0008] According to the novel three-lobed screwdriver head, the reset ring is made of rubber material.

[0009] The above solution has the following beneficial effects: The new three-part nozzle screwdriver head can hold the screw after it is blown out by the feeder, preventing it from falling out. It also uses a vacuum suction device to suck air into the bit. The bottom of the bit has an adsorption hole, which allows the screw to be adsorbed by vacuum suction. This prevents the screw from tilting and reduces the possibility of poor screw torque or the screw not being properly tightened when the torque is reached.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-4This utility model provides a novel three-lobed nozzle screwdriver head, comprising: a sleeve 1, a three-lobed nozzle 2 fixedly connected to the bottom of the sleeve 1, a feeder 7 connected to the top of the sleeve 1, a vacuum suction device 6 provided on one side of the top of the sleeve 1, and the vacuum suction device 6 connected to the screwdriver bit 4. The vacuum suction device 6 drives the screwdriver bit 4 to attract the screw 5, preventing the screw 5 from being crooked, so that the screw 5 can be locked vertically downward into the product, reducing the situation where the screw 5 has poor torque or the torque is reached but the screw 5 is not locked in place.

[0020] The bottom of the bit 4 is provided with an adsorption hole 8. The bottom of the bit 4 is used to adsorb the screw 5 through the adsorption hole 8 and the vacuum suction device 6. The screw 5 is adsorbed through the adsorption hole 8 and the vacuum suction device 6 to prevent it from tilting.

[0021] The outer wall of the three-lobed nozzle 2 is provided with a mounting groove, and a reset ring 3 is movably connected inside the mounting groove to facilitate the reset of the three-lobed nozzle 2. When the bit 4 is retracted, the three-lobed nozzle 2 will be reset under the action of the reset ring 3.

[0022] The reset ring 3 is made of rubber material, which has good elasticity and can provide elastic force for the reset of the three-lobed nozzle 2.

[0023] Working principle: After the screw 5 is blown out by the feeder 7, it enters the three-part nozzle 2. The three-part nozzle 2 holds the screw 5 to prevent it from falling out. At the same time, the bit 4 uses the vacuum suction device 6 and the suction hole 8 at the bottom to attract the screw 5 and prevent it from tilting. When screwing the screw 5, the cylinder can drive the bit 4 to extend. As the bit 4 extends downward, it attracts the screw 5 and pushes the screw 5 downward together, so that the screw 5 can be locked vertically downward into the product. This reduces the situation where the screw 5 has poor torque or the torque is reached but the screw 5 is not locked in place.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
