Abstract
Description
Technical Field
[0001] This utility model relates to a tool fastening structure, belonging to the technical field of tool fastening structures. Background Technology
[0002] Electricians and construction workers typically carry many tools for their work, such as measuring tapes, power tools, and tool bags. However, workers often need to climb or move around during construction, making it difficult to hold these tools by hand. Therefore, construction workers usually hang the tools on their work belts.
[0003] Please refer to Figure 1 As shown, a positioning fastener is disclosed, including a first piece 71, a second piece 72, a hanging body 73, an insert 74, and a stop 75. The first piece 71 and the second piece 72 cooperate with each other. The first piece 71 has a guide groove 711, and the hanging body 73 has a guide block 731. The guide block 731 is inserted into the guide groove 711, and the stop 75 controlled by the insert 74 restricts the guide block 731 to prevent the hanging body 73 from moving in the guide groove 711, so that the hanging body 73 cannot be removed. When the user presses the insert 74, the stop 75 can be retracted, allowing the hanging body 73 to be removed.
[0004] However, construction workers are often unable to stand upright during work and must maintain a tilted or curled-up standing posture. When maintaining this posture, it is difficult to apply appropriate pressure to press the insert of the positioning fastener. Often, it is necessary to deliberately increase the pressure of the thumb to remove the hanging part. Over time, this may cause discomfort to the user's hand. Therefore, an improved tool fastening structure is needed. Utility Model Content

The first limiting unit 222 is the groove wall 221A and the second limiting unit 223 is the limiting bolt 223A.
[0043] In this embodiment, please refer to Figure 2A The pivot unit 20C is a bolt that passes through the pivot and is locked to the front wall 11.
[0044] In a preferred embodiment, please refer to Figure 2A The main body 10 also has a rear wall 16, an upper connecting wall 17 and a lower connecting wall 18. The front wall 11 and the rear wall 16 are spaced apart by a distance. One end of the upper connecting wall 17 and the lower connecting wall 18 is connected to the front wall 11, and the other end of the upper connecting wall 17 and the lower connecting wall 18 is connected to the rear wall 16. A through hole 19 is formed between the front wall 11, the rear wall 16, the upper connecting wall 17 and the lower connecting wall 18. The through hole 19 is for the user to thread a belt L so that the tool fastening structure of this utility model can be fixed to the user's belt L.
[0045] In another preferred embodiment, please refer to Figure 2A The upper connecting wall 17 has a first extension 171 for engaging with another tool fastening structure, and the first extension 171 has a first common through hole 172.
[0046] In another preferred embodiment, please refer to Figure 2A The lower connecting wall 18 has a second extension 181 for engaging with another tool fastening structure.

[0048] As can be seen from the foregoing, please refer to... Figure 6A The main feature of this invention is that the end face of the swing end 20B is arc-shaped, and a portion of the swing end 20B extends into the guide groove 14. The guide surface 25 connects to the end face of the swing end 20B. Therefore, when the user needs to remove the tool 60 from the guide groove 14 of the body 10, the user only needs to lift the tool 60 upwards, and the protrusion 61 will abut against the swing end 20B. However, since the end face of the swing end 20B is arc-shaped and the protrusion 61 is also cylindrical, please refer to... Figure 6BThe user only needs to slightly rotate the tool 60 so that the protrusion 61 can rotate and press against the guide surface 25 that connects to the swing end 20B, thereby driving the pivot 20 to swing so that the swing end 20B leaves the guide groove 14 and the protrusion 61 can smoothly exit from the guide groove 14 to remove the tool 60. The user does not need to free his hand to press the pivot 20 to smoothly remove the workpiece 60, thereby achieving the purpose of quickly removing the tool.
[0049] In addition, please refer to Figure 5 Since the flange end face 241 extends into the top groove 15, and the retaining bolt 223A penetrates the front wall 11 and extends into the arc groove 221, the upper edge stop 132 can limit the flange portion 24, and the retaining bolt 223A can limit an inner sidewall 221C of the arc groove 221, thereby making the pivot member 20 more securely connected to the body 10, avoiding unnecessary shaking, and the pivot member 20 will not fall off when the pivot unit 20C is removed.
