[0034] The locking mechanism 8 is arranged in the mounting plate 73, and comprises a locking block 81, a second spring 82 and a connecting rod 83, and is used to assemble the front cover assembly 7 and the fixing block 5. One end of the locking block 81 is an inclined surface.

[0035] Furthermore, a connecting groove is provided on the mounting plate 73 for embedding the locking mechanism 8;

[0036] A through hole is formed at one end of the connection slot, a slot is formed in the through hole, a third spring 7301 is installed in the slot, a locking ball 7302 is installed on the third spring 7301, and the locking ball 7302 is slidably disposed in the slot;

[0037] There are two groups of slots, which are distributed up and down, and the corresponding third springs 7301 and locking balls 7302 are also provided;

[0038] The mounting plate 73 is further provided with a positioning hole and a mounting groove, and the mounting groove is provided with a sliding groove communicating with the connecting groove.

[0039] Furthermore, a bellows 7101 is fixedly provided at one end of the connection cover 71 , a side plate 74 is installed on the bellows 7101 , a positioning rod 7401 is installed on the side plate 74 , and the positioning rod 7401 is slidably arranged in the positioning hole.

[0040] Specifically, the arrangement of the bellows 7101 on the connecting cover 71 allows the connecting cover 71 to have a larger movable space and the movement is not hindered.

[0041] Furthermore, the first spring 72 is sleeved on the positioning rod 7401 , one end of which is connected to the mounting plate 73 , and the other end is connected to the side plate 74 . The first spring 72 provides a restoring force for the bellows 7101 .

[0042] Furthermore, the locking block 81 is slidably set in the slide groove; one end of the second spring 82 is connected to the locking block 81, and the other end is connected to the slide groove; a limiting hole is opened on the connecting rod 83, and the connecting rod 83 is slidably set in the connecting groove, one end of which is connected to the locking block 81, and the other end is installed with the first operating block 8301.

[0043] Furthermore, the locking mechanism 8 also includes: a slide rod 84, which is slidably set in the through hole, and a hemispherical groove is opened on the slide rod 84, which is used to cooperate with the locking ball 7302 to lock the position of the slide rod 84; a latch rod 85, which is installed at the bottom of the slide rod 84, and is used to cooperate with the limiting hole to lock the connecting rod 83; a second operating block 86, which is installed at the top of the slide rod 84.

[0044] Specifically, the arrangement of the slide bar 84 and the latch bar 85 further limits the connecting bar 83 and avoids the situation where the locking device is mis-locked due to accidental touch during use.

[0045] A lithium-ion electric drill, the working principle is as follows:

[0046] When in use, the front cover assembly 7 can be selected and installed according to the usage;

[0047] When installation is required:

[0048] Take the front cover assembly 7, make the position of the mounting groove on the mounting plate 73 correspond to the position of the fixing block 5, and control the mounting plate 73 to move toward the position of the fixing block 5 or the fixing block 5 to move toward the position of the mounting plate 73. When the locking block 81 contacts the fixing block 5, affected by its inclined surface, the locking block 81 is forced to move into the sliding groove, and synchronously drives the connecting rod 83 and compresses the second spring 82 until the position of the sliding groove corresponds to the locking groove. At this time, the second spring 82 is no longer under force, and the locking block 81 is driven under the force of the first spring 72, so that the locking block 81 is pushed into the locking groove to complete the installation of the front cover assembly 7. Subsequently, the second operating rod is pressed to drive the slide bar 84, so that the position of the upper hemispherical groove of the slide bar 84 moves from the position of the upper locking ball 7302 to the position of the lower locking ball 7302, and the latch rod 85 is inserted into the limiting hole. When the slide bar 84 moves, it drives the locking ball 7302 to move the locking ball 7302 into the slot hole and compresses the third spring 7301. When the hemispherical groove corresponds to the slot hole, the third spring 7301 is also no longer under force.

[0049] When you need to remove:

[0050] First, operate the second operating block 86 to disengage the latch rod 85 from the limiting hole, and then operate the first operating block 8301 to drive the connecting rod 83 and the locking block 81, thereby driving the locking block 81 to disengage from the locking groove. At this time, press the second operating block 86 again to insert the latch rod 85 into another limiting hole and lock the connecting rod 83 again, so as to prevent the locking block 81 from being pushed into the locking groove, making it easier to remove.
