Screws are a kind of fasteners commonly used in daily life and industry. At present, in use, different types of screws are generally selected for fixing according to different screw lengths and other parameters. Since the screw length is fixed at the time of manufacture, when When using a large number of screws with different screw lengths, it is necessary to sort out screws with different screw lengths beforehand. This method is more troublesome, and sometimes in some special occasions, some screws with special lengths are required. Producing screws of this particular length individually is laborious and laborious.
Contents of the utility model Guangdong Yueluo Hardware Industry Co., Ltd. is to solve the problem of needing one hand to hold the screw when screwing the screw at present, and to provide a screw fixture that can screw the screw without holding the screw by hand. Guangdong Yueluo Hardware Industry Co., Ltd. adopts the following technical solutions. Guangdong Yueluo Hardware Industry Co., Ltd. includes a clamp sleeve, and the middle of the clamp sleeve is a through hole. The outer end of the pivot pin is in contact with the spring. The beneficial effect of Guangdong Yueluo Hardware Industry Co., Ltd. is because Guangdong Yueluo Hardware Industry Co., Ltd. is provided with a rotating pin on the shaft of the fixture sleeve that can contact the screw, and the outer end of the rotating pin is in contact with the spring, so that the screw It is easy to fix in the through hole of the fixture cover, and the screwdriver is also in the through hole of the fixture cover, which ensures the alignment of the screw and the screwdriver, so it is avoided to hold the screw by hand, and the screw is quickly screwed to the object. in vivo.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35, and the screws enter the screw accommodating hole 46 from the discharge port through the guide rail 6. The slotting is carried out, which improves the efficiency and saves the labor cost.
Ordinary T-bolts, the bolt head is rectangular, the screw part and the bolt head are T-shaped, and the width of the head is smaller than the width of the opening part of the T-slot, so that the head of the T-bolt can extend from the length of the T-slot. Insert the T-slot into the T-slot at any position in the direction. When the workpiece needs to be fixed, turn the T-bolt 90 degrees so that the length of the head is perpendicular to the T-slot, hook the inside of the opening of the T-slot, and screw it by tightening The nut on the T-bolt threaded rod holds the workpiece in place. The T-bolt of this structure can easily connect the bolt and the base piece quickly, and is widely used, but there are also some shortcomings, due to the contact area between the head of the T-bolt and the inner side of the opening of the T-slot. If it is too small, the frictional resistance is correspondingly small. On the one hand, the bolts are easy to follow the rotation during the process of tightening the nut. Unreliable.
Countersunk head screw, also called countersunk head screw, also known as flat machine screw, is a kind of construction part. The head is a 90-degree cone, similar to common wood screws. The head has tool tightening grooves, such as a zigzag, cross, inner hexagon, plum blossom, pentagon, etc. Screws are all connectors used to connect two objects. Generally, the head of the screw will protrude above the surface of the object to be connected, so that the surface will lose its smoothness. Countersunk head screws can be sunk under the surface to make the surface flat. For hard objects, countersunk holes need to be drilled in the corresponding positions of the countersunk head. In short, the countersunk head is the head of the screw that can keep the surface flat after installation.
