[0024] It should be noted that during use, the solder clamp 201 is first fixed into the installation mechanism 2 through the fixing tube 202, and then one end of the solder clamp 201 contacts the locking mechanism 3. At the same time, the locking mechanism 3 is activated, and the solder clamp 201 is fixed by the cooperation between the various components. The structure of the device is relatively simple, and it is easy to operate when maintenance and replacement of parts are required.

[0025] like Figure 3As shown, a slot is provided on one side of the bottom of the drill clamp 201, a bottom plate 203 is fixedly connected in the slot, a sliding plate 204 is provided on the top of the bottom plate 203, a first spring 205 is installed between the bottom plate 203 and the sliding plate 204, and a fixing column 206 is fixedly connected to the top of the sliding plate 204.

[0026] It should be noted that during use, the drill clamp 201 and the fixed column 206 first slide with the inner wall of the fixed tube 202, and under the action of the first spring 205, the outer wall of the fixed column 206 and the inner wall of the fixed tube 202 are in the same plane and slide. When sliding to the notch opened at one end of the fixed tube 202, the first spring 205 lifts the fixed column 206 through the bottom plate 203 and the sliding plate 204 and fixes it in the notch.
