Description

Technical Field

[0001] The utility model relates to the technical field of non-inductive screwdrivers, and more precisely, to a ceramic non-inductive screwdriver. Background Art

[0002] In the fields of industrial manufacturing, electronic equipment maintenance, etc., screwdrivers with ceramic bits are widely used due to their unique non-inductive characteristics. However, there is a key problem with ceramic bits, that is, as the usage time increases, the bit gradually wears and needs to be replaced.

[0003] In the traditional connection method between the bit and the handle, for ceramic bits, there are some deficiencies. For example, the simple plug-in method is convenient, but during use, due to the relatively high hardness of the ceramic bit, when subjected to a large torque or impact force, it is prone to breakage or loosening at the connection; some connection methods use glue bonding, but this method is rather cumbersome when the bit needs to be replaced, and it is difficult to ensure the firmness of the glue bonding under long-term use and different environmental temperatures and humidities; in addition, for some connection structures fixed by mechanical means such as screws, during the frequent use of the bit, the screw may wear the connection part of the bit, and the screw itself is also prone to loosening or damage. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a ceramic non-inductive screwdriver with a stable connection structure and convenient bit replacement.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A ceramic non-inductive screwdriver includes a ceramic bit and a handle. A stepped connection post is provided at the rear end of the ceramic bit, and a stepped connection hole matching the connection post is opened at the front end of the handle. A plurality of elastic wedge-shaped blocks are evenly distributed on the side wall of the connection post, and a card slot matching the elastic wedge-shaped block is opened on the inner wall of the connection hole. A fastening ring is sleeved outside the handle.

[0007] Further, the elastic wedge-shaped block is made of rubber material.

[0008] Further, the outer surface of the handle is provided with anti-slip lines.

[0009] Further, a positioning block is provided at the end of the connection post, and a positioning slot corresponding to the positioning block is opened at the bottom of the connection hole.

[0010] Further, the fastening ring is threadedly connected to the handle.

[0011] Compared with the prior art, the beneficial effects of the utility model:

[0012] In the present utility model, the stepped connecting column at the rear end of the ceramic bit is matched with the stepped connecting hole at the front end of the handle. This design increases the contact area between the bit and the handle. Compared with the traditional simple plug-in method, it can withstand greater torque and impact force, thereby improving the firmness of the connection. An elastic wedge-shaped block is arranged between the connecting column and the connecting hole. When the connecting column is inserted into the connecting hole, the wedge-shaped block can be stuck into the card slot. This design utilizes the self-locking characteristic of the wedge-shaped structure, making the bit and the handle not easily displace relative to each other when subjected to external forces, further enhancing the stability of the connection. The fastening ring arranged on the outer side of the handle can further fasten the connection between the connecting column and the connecting hole, and can effectively prevent the connection from loosening when subjected to large torque or impact force. The overall connection structure ensures firmness without adopting overly complex or difficult-to-operate connection methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] As Figure 1 and Figure 2 shown, a ceramic non-inductive bit includes a ceramic bit 1 and a handle 2. A stepped connecting column 3 is arranged at the rear end of the ceramic bit 1, and a stepped connecting hole 201 matching the connecting column 3 is opened at the front end of the handle 2. A plurality of elastic wedge-shaped blocks 4 are evenly distributed on the side wall of the connecting column 3, and a card slot 202 matching the elastic wedge-shaped block 4 is opened on the inner wall of the connecting hole 201. A fastening ring 5 is sleeved on the outer side of the handle 2.

[0017] The elastic wedge-shaped block 4 is made of rubber material; rubber has a certain elasticity and can play a buffering role during the connection process of the ceramic bit 1 and the handle 2, avoiding damage to the connection part of the ceramic bit 1 due to direct rigid contact with the handle 2. At the same time, the elasticity of rubber helps the elastic wedge-shaped block 4 to better be stuck into the card slot 202, enhancing the stability of the connection.

[0018] The outer surface of the handle 2 is provided with anti-slip lines; the friction between the hand and the handle 2 is increased. When using the tool, it can effectively prevent the tool from slipping out of the hand, improving the safety and stability of the operation.

[0019] One end of the connecting column 3 is provided with a positioning block 6, and a positioning groove 203 corresponding to the positioning block 6 is opened at the bottom of the connecting hole 201; this can play a role in quickly positioning when installing the ceramic bit 1, making the connection between the ceramic bit 1 and the handle 2 more accurate and efficient, reducing the adjustment time during the installation process, and improving work efficiency.

[0020] The fastening ring 5 and the handle 2 are connected by threads; this connection method makes the operation of the fastening ring 5 more precise and reliable. By rotating the fastening ring 5, the fastening force can be flexibly adjusted according to actual needs, and the threaded connection has self-locking property, which can maintain the fastened state after fastening, ensuring the stability of the connection between the ceramic bit 1 and the handle 2.

[0021] Installation process: Insert the connecting column 3 at the rear end of the ceramic bit 1 into the connecting hole 201 at the front end of the handle 2. The elastic wedge-shaped clamping block 4 on the connecting column 3 undergoes elastic deformation under the extrusion of the inner wall of the connecting hole 201 during the insertion process. When the elastic wedge-shaped clamping block 4 reaches the position of the clamping groove 202, the elastic wedge-shaped clamping block 4 snaps into the clamping groove 202 under its own elastic force to achieve preliminary positioning; at the same time, the positioning block 6 at the end of the connecting column 3 is inserted into the positioning groove 203 at the bottom of the connecting hole 201 to further ensure the accurate installation position of the ceramic bit 1; then, by rotating the fastening ring 5 outside the handle 2, since the fastening ring 5 and the handle 2 are connected by threads, the fastening ring 5 will move axially along the handle 2, applying an axial pressure to the connecting column 3 to make the fit between the connecting column 3 and the connecting hole 201 closer, thus completing the entire installation process.

[0022] Usage process: When operating with the ceramic non-inductive bit, when subjected to torque or impact force, the stepped connection structure, the cooperation between the elastic wedge-shaped clamping block 4 and the clamping groove 202, and the fastening effect of the fastening ring 5 jointly ensure the stability of the connection between the ceramic bit 1 and the handle 2, enabling the tool to work properly.

[0023] Process of replacing the bit: When it is necessary to replace the worn ceramic bit 1, rotate the fastening ring 5 in the reverse direction to relieve the pressure on the connecting column 3, and then pull out the ceramic bit 1 from the handle 2.

[0024] The utility model combines various design elements such as a stepped structure, an elastic wedge-shaped clamping block 4, a clamping groove 202, a fastening ring 5, etc., ensuring a firm connection between the ceramic bit 1 and the handle 2 from multiple aspects. Whether in normal use or under complex working conditions, problems such as fracture and loosening at the connection can be effectively avoided, ensuring the reliability and service life of the tool; the entire technical solution reflects high convenience and efficiency during the installation, use, and replacement of the ceramic bit 1. The quick positioning, simple insertion operation, and convenient fastening and disassembly process reduce the cumbersome steps during the operation, improve work efficiency, and save time and labor costs; the elastic wedge-shaped clamping block 4 made of rubber and the reasonable structural design play a certain protective role for the ceramic bit 1 while ensuring a firm connection, reducing the damage to the ceramic bit 1 caused by an unreasonable connection structure, extending the service life of the ceramic bit 1, and reducing the use cost.
