Description

Anti-slip disassembly hand tools

This invention relates to a hand tool, in particular to a self-tapping screw for disassembling a corrugated board and an anti-stripping disassembly hand tool capable of preventing the socket screw from coming off.

Please refer to FIG. 1 , which discloses a conventional disassembly hand tool for disassembling and assembling self-tapping screws of a wave board. The disassembly hand tool comprises a rod 1 and a barrel 2. The rod 1 has a first shaft 3 and a second shaft 4. The first shaft 3 of the rod 1 can be connected to an electric tool, and the second shaft 4 of the rod 1 is sleeved with the barrel 2. The barrel 2 can be sleeved with a self-tapping screw for rotating disassembly and assembly.

However, when the user inserts the barrel 2 into the self-tapping screw for operation, the barrel 2 and the self-tapping screw are only sleeved, and the fixing between the two is insufficient, resulting in the self-tapping screw being easily separated from the barrel 2 during the rotation operation. The user needs to repeatedly sleeve and rotate the self-tapping screw to complete the disassembly and assembly operation of the self-tapping screw, which increases the difficulty and inconvenience of the operation.

In addition, the length of the second shaft 4 of the rod 1 is significantly shorter than the depth of the hole connected to the cylinder 2, resulting in insufficient joint strength between the rod 1 and the cylinder 2. The insufficient strength of the combination of the two easily causes the rod 1 and the cylinder 2 to separate, causing the user to have to repeatedly reassemble the two components during operation, adding to the user's operational troubles.

In order to solve the above-mentioned problem, this invention provides an anti-detachment disassembly hand tool, which can prevent the sleeve screw from detaching through the magnetic adsorption of the magnetic part, so as to improve the stability of operation.

An embodiment of the present invention provides an anti-slip disassembly hand tool, which includes: a connecting rod, which has a first part and a second part arranged oppositely, and a third part between the first part and the second part, wherein the first part can be connected to an electric tool, wherein the outer diameter of the third part is larger than the outer diameters of the first part and the second part, and the end face of the second part is provided with a groove relative to the axial recess of the connecting rod; and a magnetic part, which is arranged in the groove of the connecting rod, and part of the magnetic part is exposed outside the groove.

In one of the embodiments, the invention further has a sleeve that can be detachably sleeved on the second portion of the connecting rod, and one end of the sleeve abuts against the third portion of the connecting rod; the sleeve has a first connecting hole and a second connecting hole, the hole diameter of the first connecting hole is smaller than the hole diameter of the second connecting hole, the first connecting hole of the sleeve completely covers the second portion of the connecting rod, and the second connecting hole of the sleeve can be sleeved with a screw.

In one embodiment, the portion of the magnetic member exposed outside the groove is located at the second connecting hole of the sleeve.

In one embodiment, the axial length of the first portion relative to the connecting rod is greater than the axial length of the second portion relative to the connecting rod, and the axial length of the second portion relative to the connecting rod is greater than the axial length of the third portion relative to the connecting rod.

In one embodiment, the axial length of the first portion relative to the connecting rod is at least 1.5 times the axial length of the second portion relative to the connecting rod, and the axial length of the second portion relative to the connecting rod is at least 1.5 times the axial length of the third portion relative to the connecting rod.

Another embodiment of the present invention provides an anti-slip disassembly hand tool, which includes: a connecting rod, which has a first part and a second part arranged oppositely, and a third part between the first part and the second part, the first part can be connected to the electric tool, wherein the outer diameter of the third part is larger than the outer diameters of the first part and the second part, and the end face of the second part is provided with a groove relative to the axial concave of the connecting rod; and a magnetic part, which is embedded in the groove of the connecting rod.

In one embodiment, the end surface of the magnetic member is flush with the end surface of the second portion.

Based on the above, the invention sets a magnetic part on the connecting rod, and uses the magnetic property of the magnetic part to attract the screw part, so as to prevent the screw part connected by the sleeve from being easily separated, thereby effectively improving the stability during operation and preventing operational errors.

Furthermore, the invention increases the stability of the connection with the sleeve by using the longer second part of the connecting rod to prevent the sleeve from detaching from the connecting rod, thereby enhancing the stability of the operation and improving the problem of low connection strength with the sleeve due to insufficient length of the conventional connecting rod.
