The torsion spring 74 accumulates elastic restoring force. On the other hand, the latching end portions 56a, 56b of the grip 50 are extended into the accommodating space 72 and penetrate the inner wall surface of the notch 25 through the soft rubber pad 58, so that the battery case 20 is restricted and cannot be removed.

When the user needs to remove the battery box 20, the user can push the toggle key 61 forward, so that the pin 62 compresses the compression spring 73 forward and the compression spring 73 starts to accumulate elastic restoring force until the pin 62 is no longer connected to the jack. 52 (as in Figure 7A). At this time, the grip 50 is no longer subject to the interference of the latch 62, and the grip 50 will simply begin to pivot upward to the open position under the action of the elastic restoring force accumulated by the torsion spring 74 (as shown in FIG. 8), and click against the end 56a, 56b will also leave the notch 25 as the grip 50 pivots (that is, it will no longer catch on the inner wall surface of the notch 25), and the pushing end 57 will also enter the accommodation as the grip 50 pivots The space 72 comes into contact with the rear groove wall of the abutting groove 24. After that, the user can easily hold the grip portion 51 of the grip 50 and push the battery case 20 by pushing against the end portion 57 to move the battery case 20 backward and stop the knife gate 431 connected to the control box 43 (As shown in Figure 8). At this time, the user can hold the notch 25 of the battery case 20 and take out the entire battery case 20 from the assembly mechanism 30 along the slide rail 42 (as shown in FIG. 9).

On the other hand, please refer to Figures 3 and 9. When the user needs to install the battery case 20, the user only needs to push the battery case 20 along the slide rail 42 and make the pushing end portion 57 cross the front wall 26 of the battery case 20 and contact the pushing end portion 57 When abutting the groove wall at the rear end of the groove 24 (as shown in FIG. 7B), pivot the grip 50 downward to the closed position (as shown in FIG. 6B), so that the card abutting ends 56a, 56b re-enter the accommodation space 72 and click. Abutting the inner wall of the notch 25, the latch pin 62 can also simply move backward and insert the socket (as shown in FIG. 6A) under the elastic restoring force accumulated by the compression spring 73, thereby fixing the grip 50 and the battery case 20.

In summary, the assembly 10 of this embodiment can indeed disassemble the battery case 20 in a relatively labor-saving manner through the grip 50, and when the battery case 20 is installed in the assembly mechanism 30, the grip 50 can indeed be able to resist the The ends 56a, 56b are used to fix the battery case 20, thereby positioning the battery case 20 more effectively and accurately.
