Description

Technical Field

[0001] This utility model relates to the technical field of bolt assembly and disassembly tools, specifically a miniature bolt quick assembly and disassembly tool. Background Technology

[0002] Miniature bolts are precision mechanical fasteners primarily used to secure two parts with through holes. Compared to conventional bolts, miniature bolts are smaller and more precise, typically used in applications with strict space and weight constraints. The high manufacturing precision of miniature bolts ensures the stability and reliability of the connection; their smaller size makes them suitable for space-constrained environments; and their lighter weight helps reduce the overall weight of the structure. Miniature bolts can be manufactured using various materials, such as carbon steel, stainless steel, copper, and aluminum, to meet the needs of different applications.

[0003] Screw clamps, also known as screw holders, are categorized into magnetic, pneumatic, and clamping types. Magnetic clamps are primarily used to hold magnetic materials such as carbon steel and cast iron. Pneumatic clamps have a wider range of applications and do not have special requirements for screw material, but they require an air pump and pneumatic circuit, making them expensive and often used in production lines. Clamping clamps are mostly mechanical and commonly made of plastic. They utilize the elasticity of the plastic to restrain the screw and bit, thus achieving screw clamping and quick assembly / disassembly. They do not have special requirements for screw material and are considered manual tools.

[0004] Currently available clamping screw fasteners are made of plastic and feature two V-shaped clamping heads. Due to the plastic material, they possess a degree of elasticity. The shaft uses evenly distributed arcs, with a minimum dimension smaller than the outer diameter of the screwdriver bit. This elasticity also helps to hold the bit during installation. However, these tools are ineffective at clamping stainless steel screws, especially countersunk or thin flat-head screws. The elasticity of the clamping heads is not ideal, leading to errors or the screw jumping out of the clamping heads. Therefore, a miniature bolt quick-release tool is proposed to address these problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a miniature bolt quick-release tool, which has the advantages of quick bolt installation and removal. It solves the problem that common tools may fail to hold stainless steel screws, especially countersunk or thin flat-head screws, or the screw may jump directly out of the clamping head.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tool for quick installation and removal of miniature bolts includes an electric wrench, wherein a bit is slidably mounted on the output end of the electric wrench, and a miniature bolt limiting clamp is sleeved on one end of the bit;

[0008] The miniature bolt limiting chuck includes a guide tube sleeved on the surface of the bit, a clamping head slidably mounted on the surface of the guide tube, two clamping plates fixedly mounted on one side of the clamping head, a compression spring sleeved on the surface of the guide tube, one end of the compression spring contacting one side of the clamping head, and the two clamping plates being adapted to the head of the miniature bolt.

[0009] Furthermore, a limiting block is fixedly installed at one end of the guide tube, and a limiting groove adapted to the limiting block is opened inside the clamping head.

[0010] Furthermore, a clamping screw tube is fixedly installed at one end of the guide tube, and the clamping screw tube consists of two outwardly opening half tubes.

[0011] Furthermore, a locking nut is threaded onto the surface of the clamping screw tube, and the bit is inserted inside the clamping screw tube.

[0012] Furthermore, one side of the compression spring contacts one side of the locking nut.

[0013] Furthermore, the output end of the electric wrench is fixedly equipped with a mounting sleeve, and the bit is inserted inside the mounting sleeve.

[0014] Furthermore, a handle is fixedly installed at the tail end of the electric wrench, a switch is fixedly installed on the surface of the electric wrench, and a display screen is fixedly installed on the surface of the electric wrench.

[0015] Compared with the prior art, this utility model provides a miniature bolt quick-installation and removal tool, which has the following beneficial effects:

[0016] 1. This miniature bolt quick-installation and removal tool works by sequentially mounting a clamping head, a compression spring, and a locking nut onto a guide tube, and then placing the guide tube onto a screwdriver bit. When installing a miniature bolt, the bolt head is clamped in the clamping head. An electric wrench rotates the screwdriver bit, which in turn rotates the clamping head, installing the miniature bolt into the threaded hole. When the clamping head contacts the mounting surface, the miniature bolt continues to enter the threaded hole. The clamping head retracts under the action of the compression spring. During disassembly, the clamping head holds the head of the miniature bolt to prevent it from falling off. This solves the common problem of errors or the screw jumping out of the clamping head when using tools to hold stainless steel screws, especially countersunk or thin flat-head screws.

[0017] 2. This miniature bolt quick-assembly and disassembly tool has a clamping screw tube at the end of the guide tube. After the guide tube is fitted onto the bit, the locking nut is tightened. The locking nut moves on the clamping screw tube, which clamps the bit, so that the guide tube rotates synchronously when the bit rotates. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This embodiment of a miniature bolt quick-release tool includes an electric wrench 1, with a bit 2 slidably mounted on the output end of the electric wrench 1, and a miniature bolt limiting clamp sleeved on one end of the bit 2.

[0025] The miniature bolt limiting chuck includes a guide tube 3 fitted onto the surface of the bit 2. A clamping head 4 is slidably mounted on the surface of the guide tube 3. Two clamping plates 41 are fixedly mounted on one side of the clamping head 4. A compression spring 7 is fitted onto the surface of the guide tube 3, with one end of the compression spring 7 contacting one side of the clamping head 4. The two clamping plates 41 are adapted to the head of the miniature bolt. The two clamping plates 41 are elastic. In use, the head of the miniature bolt is clamped between the two clamping plates 41, the guide tube 3 is fitted onto the surface of the bit 2, and the electric wrench 1 drives the bit 2 to rotate, thereby driving the miniature bolt to rotate.

[0026] Secondly, a limiting block 31 is fixedly installed at one end of the guide tube 3, and a limiting groove adapted to the limiting block 31 is opened inside the clamping head 4. When the guide tube 3 rotates, the clamping head 4 rotates accordingly.

[0027] Specifically, the two clamping plates 41 are elastic. In use, the head of the micro bolt is clamped between the two clamping plates 41, the guide tube 3 is sleeved on the surface of the bit 2, and the electric wrench 1 drives the bit 2 to rotate, which in turn drives the micro bolt to rotate, preventing the micro bolt from falling off.

[0028] Meanwhile, a clamping screw tube 5 is fixedly installed at one end of the guide tube 3. The clamping screw tube 5 consists of two outwardly opening half tubes.

[0029] The clamping screw tube 5 has a locking nut 6 threaded onto its surface, and the bit 2 is inserted inside the clamping screw tube 5. Tightening the locking nut 6 causes the clamping screw tube 5 to clamp inward onto the surface of the bit 2.

[0030] Secondly, one side of the compression spring 7 contacts one side of the locking nut 6. When installing the miniature bolt, the head of the miniature bolt is clamped in the middle of the two clamping plates 41. As the miniature bolt is continuously screwed into the mounting surface, the two clamping plates 41 first contact the mounting surface. As the miniature bolt continues to advance, the clamping head 4 retracts, compressing the compression spring 7.

[0031] Meanwhile, the output end of the electric wrench 1 is fixedly equipped with an installation sleeve 8, and the bit 2 passes through the inside of the installation sleeve 8. During installation, the clamping head 4, compression spring 7, and clamping screw tube 5 are sequentially placed on the guide tube 3, then the guide tube 3 is placed on the bit 2, and finally the locking nut 6 is tightened.

[0032] The electric wrench 1 has a handle 9 fixedly installed at its tail end, a switch 10 fixedly installed on its surface, and a display screen 11 fixedly installed on its surface.

[0033] The working principle of the above embodiment is as follows: the two clamping plates 41 are elastic. When in use, the head of the micro bolt is clamped between the two clamping plates 41, the guide tube 3 is sleeved on the surface of the bit 2, and the electric wrench 1 drives the bit 2 to rotate, thereby driving the micro bolt to rotate.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply.
