Description

Technical Field

[0001] The utility model relates to the field of three-in-one connecting rod installation, in particular to a metal ring used for three-in-one connecting rod installation. Background Art

[0002] The magnetic ring is a device that assists the hand drill in installing the three-in-one connecting rod. The magnetic ring is a straight tube structure. The drill bit of the hand drill extends into the magnetic ring from one end of the magnetic ring, and the three-in-one connecting rod head extends into the magnetic ring from the other end of the magnetic ring. The drill bit rests on the connecting rod head. No hand support is required. Only one hand is needed to operate the hand drill to drive the three-in-one connecting rod into the corresponding hole, making the driving process convenient and safe. However, the existing three-in-one installation sleeve structure is too simple, and the drill bit cannot be replaced and reused. At the same time, the inner wall diameter of the sleeve is too large, and it needs to be shaken and clamped in during the clamping process of the connecting rod and the drill bit, which causes severe wear on the drill bit. At the same time, relying solely on the magnetic force of the drill bit itself cannot ensure that the connecting rod does not slip when it is vertically downward in the sleeve. Utility Model Content

[0003] The main purpose of the utility model is to provide a magnetic three-in-one connecting rod stably installed metal ring, by arranging a magnetic ring in the metal ring, so that the connecting rod will not fall out of the metal ring when the metal ring is placed vertically.

[0004] The utility model proposes a metal ring for installing a three-in-one connecting rod. The metal ring is a straight tube structure, one end of which is open as a hole for inserting the three-in-one connecting rod, and the other end is a hole for inserting a screwdriver bit. The inner wall of the magnetic ring is provided with a first magnetic ring for magnetically attracting and stabilizing the three-in-one connecting rod and a second magnetic ring for enhancing the magnetic force of the screwdriver bit. The inner wall of the metal ring is provided with a clamping ring for tightening the screwdriver bit. The screwdriver bit is combined in the metal ring by tightening the clamping ring. The screwdriver bit can be pulled out and can be replaced by itself and reused. The screwdriver bit is combined in the metal ring by tightening the clamping ring, rather than being fixed in the metal ring by static friction generated by close contact with the inner wall of the metal ring, which can avoid large-area wear of the screwdriver bit.

[0005] Preferably, the clamping ring is provided with two circles, and the clamping rings are distributed at both ends of the second magnetic circle. When the beater head is clamped and fixed in place, the second magnetic circle is ensured to face the beater head, that is, it can absorb the beater head and enhance the magnetic force of the bit, so as to enhance the magnetic attraction between the beater head and the three-in-one connecting rod, making the matching of the two more stable.

[0006] Under the action of the two magnetic circles, the screwdriver bit and the three-in-one connecting rod can be stably inserted, so that the three-in-one connecting rod is not easy to fall off vertically during the installation process.

[0007] Preferably, the clamping ring is a rubber ring which will not wear the head.

[0008] Preferably, the diameter of the inner wall of the metal ring is set to be slightly larger than the diameter of the three-in-one connecting rod, so as to avoid the connecting rod shaking left and right and sliding off during the installation process due to the excessively large installation inner diameter of the three-in-one connecting rod.

[0009] Preferably, the outer wall surface of the metal ring on which the three-in-one connecting rod is installed is provided with a marking portion for distinguishing the three-in-one connecting rod insertion hole and the bit insertion hole. The marking portion is an annular recessed position close to the bit insertion hole.

[0010] When installing the three-in-one connecting rod, the three-in-one connecting rod head extends from the three-in-one connecting rod insertion hole into the metal ring under the magnetic attraction of the first magnetic ring, and the metal head of the three-in-one connecting rod is adsorbed to the position of the first magnetic ring; the screwdriver bit extends from the screwdriver bit insertion hole into the metal ring, and the clamping ring is close to the side of the screwdriver bit, so that the screwdriver bit is fastened in the metal ring. The screwdriver bit is against the three-in-one connecting rod head. When the screwdriver bit acts on the three-in-one connecting rod head, the screwdriver bit will drive the metal ring and the three-in-one connecting rod to rotate together, so that the three-in-one connecting rod is driven into the hole.

[0011] The beneficial effects of the utility model are:

[0012] The inner wall of the metal ring is provided with a clamping ring for tightening the bit. The bit is tightened by the clamping ring and combined in the metal ring. The bit can be pulled out and can be replaced by yourself and reused. The bit is tightened by the clamping ring and combined in the metal ring, rather than being fixed in the metal ring by the static friction generated by close contact with the inner wall of the metal ring, which can avoid large-scale wear of the bit. At the same time, a second magnetic circle is set in the metal ring to adsorb the bit. The bit can be inserted into the metal ring with the help of the adsorption force of the second magnetic circle, which is more labor-saving. The second magnetic circle can enhance the magnetic force of the bit to enhance the magnetic attraction between the bit and the three-in-one connecting rod, so that the two match more stably. The setting of the first magnetic circle and the second magnetic circle ensures that the three-in-one connecting rod will not fall out of the metal ring when the metal ring is placed vertically.

[0018] Reference Figure 1 , an embodiment of the three-in-one connecting rod installation metal ring of the utility model is proposed:

[0019] A three-in-one connecting rod installation metal ring, the metal ring is a straight tube structure, one end is open for the three-in-one connecting rod insertion hole 11, and the other end is for the screwdriver bit insertion hole 12. The inner wall of the metal ring is provided with a first magnetic ring 21 for magnetically attracting the three-in-one connecting rod, a second magnetic ring 22 for magnetically attracting the screwdriver bit, and a clamping ring 31 for tightening the screwdriver bit, and the size of the clamping ring 31 is adapted to the screwdriver bit. The screwdriver bit is combined in the metal ring by tightening the clamping ring 31, and the screwdriver bit can be pulled out and replaced by oneself and reused. The screwdriver bit is combined in the metal ring by tightening the clamping ring 31, rather than being fixed in the metal ring by the static friction generated by close contact with the inner wall of the metal ring, which can avoid large-area wear of the screwdriver bit.

[0020] When installing the three-in-one connecting rod, the three-in-one connecting rod head extends from the three-in-one connecting rod insertion hole into the metal ring under the magnetic attraction of the first magnetic ring 21, and the metal head of the three-in-one connecting rod is adsorbed to the position of the first magnetic ring 21; the screwdriver bit extends from the screwdriver bit insertion hole into the metal ring, and the clamping ring 31 is close to the side of the screwdriver bit, so that the screwdriver bit is fastened in the metal ring. The screwdriver bit is against the three-in-one connecting rod head. When the screwdriver bit acts on the three-in-one connecting rod head, the screwdriver bit will drive the metal ring and the three-in-one connecting rod to rotate together, so that the three-in-one connecting rod is driven into the hole.

[0021] When inserting the bit, the bit can be inserted into the metal ring with the help of the adsorption force of the second magnetic circle 22, which is more labor-saving, and the second magnetic circle 22 can enhance the magnetic force of the bit to enhance the magnetic attraction between the bit and the three-in-one connecting rod, making the matching of the two more stable. The setting of the first magnetic circle 21 and the second magnetic circle 22 ensures that the three-in-one connecting rod will not fall out of the metal ring when the metal ring is placed vertically.

[0022] Specifically, the clamping ring 31 is provided with two circles, and the clamping ring 31 is distributed at both ends of the second magnetic circle 22. One clamping ring 31 is adjacent to the first magnetic circle 11. When the head is clamped and fixed in place, the second magnetic circle 22 is ensured to face the head, that is, the head is adsorbed and the magnetic force of the bit is enhanced, so as to enhance the magnetic attraction between the head and the three-in-one connecting rod, making the matching of the two more stable.

[0023] The clamping ring 31 is a rubber ring, which can not wear the head. In other embodiments, the clamping ring 31 can also be a spring clamping ring.

[0024] The diameter of the inner wall of the metal ring is set to be slightly larger than the diameter of the three-in-one connecting rod, so as to prevent the connecting rod from shaking left and right and slipping during the installation process due to the installation inner diameter of the three-in-one connecting rod being too large.

[0025] The outer wall surface of the metal ring is provided with a marking portion 4 for distinguishing the connecting rod insertion hole 11 and the screwdriver bit insertion hole 12. In the embodiment of the utility model, the marking portion 4 is an annular concave position close to the screwdriver bit insertion hole 12, which has a marking function and is convenient for holding the metal ring.

[0026] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
