[0002] When existing power tools such as electric hammers and electric drills are produced or used, corresponding tests need to be carried out, such as passing or failing tests or testing relevant parameters. To avoid interference from external or human factors during testing, the tool to be tested usually needs to be fixed on a test bench. Existing testing devices usually use clamps adapted to the shape of the tool to be tested for fixation. Therefore, only power tools of the same type and the same model can be tested. When another power tool needs to be tested, the clamp or the entire testing device needs to be replaced, which is troublesome to operate, has low testing efficiency, and has a high cost due to the need to configure multiple sets of clamps or testing devices.

[0027] This embodiment provides a fixing device for an electric tool, which includes: a mounting base 100 and at least two groups of clamping and fixing components 200 symmetrically arranged on the mounting base 100. Each group of clamping and fixing components 200 includes a vertical support rod 201, a horizontal support rod 202, a sliding connection block 203 and a clamping mechanism 204. A plurality of fixing holes 101 are arranged in an array on the mounting base 100. The vertical support rod 201 can be installed at any fixing hole 101. The sliding connection block 203 is slidably installed on the vertical support rod 201. The horizontal support rod 202 is connected to the sliding connection block 203, and the horizontal support rod 202 is perpendicular to the vertical support rod 201. The clamping mechanism 204 is slidably arranged on the horizontal support rod 202. The electric tool 700 to be tested is fixed between the clamping mechanisms 204 of the two groups of clamping and fixing components 200.

[0028] Please refer to Figure 1As shown in the figure, in this embodiment, the mounting base 100 is arranged in a plate-like structure. Fixing holes 101 are arranged at intervals on the mounting base 100. Fixing devices such as studs or pins can be inserted into the fixing holes 101 for fixing the vertical support rod 201. Two sets of clamping and fixing components 200 are arranged on the mounting base 100. The two sets of clamping and fixing components 200 are symmetrically arranged, and the power tool 700 to be tested is clamped between the two sets of clamping and fixing components 200. Specifically, the clamping and fixing component 200 includes a vertical support rod 201 and a horizontal support rod 202. The vertical support rod 201 is vertically arranged on the mounting base 100. The lower end of the vertical support rod 201 can be installed at any fixing hole 101, and the vertical support rod 201 is detachably connected to the mounting base 100 through devices such as studs or pins. Before the operator performs the test operation, the installation position of the vertical support rod 201 can be adjusted as needed, so as to adjust the distance between the two sets of clamping and fixing components 200 to adapt to power tools of different widths. A sliding connection block 203 is slidably arranged on the vertical support rod 201. The horizontal support rod 202 is arranged on the sliding connection block 203, and the horizontal support rod 202 and the vertical support rod 201 are perpendicular to each other.

The clamping mechanism 204 can move along the length direction of the horizontal support rod 202, so as to adjust the clamping mechanism 204 to the required position to fix the power tool 700 to be tested. In this embodiment, by cooperating the vertical support rod 201 with the fixing holes 101 on the mounting base 100, the installation distance and installation position of the clamping and fixing component 200 are adjusted. Then, by adjusting the sliding connection block 203 to move the horizontal support rod 202 up and down, the height of the clamping mechanism 204 is adjusted. Finally, the horizontal position of the clamping mechanism 204 is adjusted along the horizontal support rod 202, so as to realize the position adjustment of the clamping mechanism 204 in multiple directions, thereby adapting to the clamping and fixing of power tools of different models and sizes. It can be understood that when testing power tools, since the external structures and sizes of different power tools are different, appropriate fixtures are needed for fixing during the fixing process to ensure the stability of the power tool during the test. The power tool fixing device provided in this embodiment can meet the fixing of power tools of any model by adjusting the distance, height and horizontal position of the clamping mechanism 204. Only one fixing device is needed to meet the fixing requirements, reducing the number of fixing jigs and thus reducing the test cost.
