Description

Technical Field

[0001] The utility model relates to a tightening tooling, in particular to a novel extended tightening tooling. Background Art

[0002] In the production and manufacturing process of the junction box of new energy vehicles, bolts need to be tightened in the narrow places inside the box body. However, the tightening tools cannot meet the requirements of tightening torque, and the length of the tightening tools is not enough to match the bolts in the interference part.

[0003] To sum up, the utility model designs a novel extended tightening tooling. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a novel extended tightening tooling, with reasonable structural design, convenient and reliable operation, capable of meeting the requirements of tightening torque in narrow spaces, and having strong practicability.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: A novel extended tightening tooling includes an extension rod and a ratchet head. The head of the extension rod is provided with a ratchet head, the tail of the extension rod is inserted into the head of a wireless wrench, and the ratchet head is sleeved with a socket.

[0006] Preferably, the ratchet head includes a ratchet body, an upper cover and a base. The base is integrally designed with the head of the extension rod, the base cooperates with the upper cover, and the ratchet body is arranged in the box body formed by the base and the upper cover.

[0007] Preferably, the extension rod is of a rod-shaped structure.

[0008] The beneficial effects of the utility model: The utility model has a reasonable structural design, can meet the requirements of tightening torque in narrow spaces, is convenient and reliable to use, and has strong practicability. Brief Description of the Drawings

[0009] The following combines the drawings and specific embodiments to detail the utility model;

[0010] Figure 1 is the structural schematic diagram of the utility model;

[0011] Figure 2 is the exploded schematic diagram of the utility model. Detailed Description of the Embodiments

[0012] To make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the following further elaborates the utility model in combination with specific embodiments.

[0013] Refer to Figure 1-2, this specific embodiment adopts the following technical solution: a new type of extended tightening tooling, including an extension rod 1 and a ratchet head 2. The head of the extension rod 1 is provided with the ratchet head 2. The tail of the extension rod 1 is inserted into the head of the wireless wrench, and the ratchet head 2 is sleeved with a socket.

[0014] It should be noted that the ratchet head 2 includes a ratchet body 21, an upper cover 22 and a base 23. The base 23 is integrally designed with the head of the extension rod 1. The base 23 cooperates with the upper cover 22, and the ratchet body 21 is arranged in the box formed by the base 23 and the upper cover 22.

[0015] In addition, the extension rod 1 is a rod-shaped structure.

[0016] This specific embodiment is mainly composed of the extension rod 1 and the ratchet head 2. The overall design is reasonable. Insert the tail of the present invention into the head of the wireless wrench to combine it with the wireless wrench. Then, put the corresponding socket on the ratchet head and use the length advantage to send the socket to a narrow place inside the box to match the bolt at this position. Pull the wireless wrench to tighten the bolt.

[0017] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
