[0002] A drilling machine is a general term for machines and equipment that use a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object by means of rotary cutting or rotary extrusion. Among them, handheld drilling machines are small and portable, and their application range is getting wider and wider. During the use of handheld drilling machines, the handheld drilling machine is mostly powered by connecting to an external power source or charging its fixed lithium battery. However, for rechargeable handheld drilling machines, personnel are required to charge them in time when the lithium battery is low. During this process, the handheld drilling machine cannot be used for drilling operations. In view of this, we propose a lithium battery that is easy to replace for a handheld drilling machine.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 As shown, the utility model provides a technical solution:

[0020] Embodiment 1: A lithium battery that is easily replaced for a handheld drilling machine comprises a drilling machine body 1 and a lithium battery block 3. A battery slot 11 is provided at the rear of the drilling machine body 1, and connecting sliders 12 are symmetrically provided on both sides of the battery slot 11. A battery baffle 2 is movably plugged into the top of the rear end of the drilling machine body 1, and anti-slip grooves 21 are evenly provided on the rear side wall of the battery baffle 2 to increase the friction between the personnel's hands and the battery baffle 2, so that the personnel can easily push the battery baffle 2 upward, so that the lithium battery block 3 can be taken out of the battery slot 11, and the personnel can easily replace the lithium battery block 3 without stopping to charge it. A clamping protrusion 31 is provided at the rear of the lithium battery block 3, and the rear end surface of the clamping protrusion 31 is an inclined surface. Through cooperation with the battery baffle 2, the lithium battery block 3 can be gradually pressed against the battery baffle 2 during the process of moving the battery baffle 2 downward, which can effectively prevent the lithium battery block 3 from loosening, thereby ensuring its stable power supply to the drilling machine body 1. The lithium battery block 3 is symmetrically opened on both sides. The battery baffle 2 is manually pressed downward to squeeze the pressing protrusion 31 at the lower end of the battery baffle 2. Since the rear side of the pressing protrusion 31 is inclined, the lithium battery block 3 can be gradually pushed forward during the downward movement of the battery baffle 2 until the battery baffle 2 is pressed to the lowest position. At this time, the pressing protrusion 31 abuts against the battery baffle 2, which can effectively prevent the lithium battery block 3 from loosening, and the lithium battery can be quickly replaced without stopping the battery for charging.

[0021] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the top of the drilling machine body 1 on the front side of the battery baffle 2 is fixedly connected with a seat body 4, the interior of the seat body 4 is elastically connected with a slide seat 6 through a spring 5, the spring 5 inside the seat body 4 is provided at two locations, the front ends of the two springs 5 ​​are fixedly connected to the inner wall of the seat body 4, the rear ends of the two springs 5 ​​are fixedly connected to the front end surface of the slide seat 6, a toggle handle 61 is provided on the top of the slide seat 6, the toggle handle 61 slides along the avoidance groove 41 opened on the top of the seat body 4, and an anti-loosening pin 62 is provided at the rear end of the slide seat 6, and the anti-loosening pin 62 is connected to the anti-loosening hole 22 opened on the battery baffle 2 By means of the matching connection, the position of the battery baffle 2 can be locked by inserting the anti-loosening pin 62 into the anti-loosening socket 22, thereby further preventing the battery baffle 2 from loosening. After the battery baffle 2 is pressed to the lowest position, the slide 6 can be driven to move backward under the elastic force of the spring 5, so that the anti-loosening pin 62 is automatically inserted into the anti-loosening socket 22 to lock the battery baffle 2. When the battery baffle 2 needs to be pushed upward, the toggle handle 61 can be manually pushed forward first to drive the slide 6 to move forward, so that the anti-loosening pin 62 is removed from the anti-loosening socket 22, and the battery baffle 2 can be pushed upward to open.

[0022] Working principle: When replacing a lithium battery, the battery baffle 2 can be manually pushed upwards to pull the lithium battery block 3 out of the battery slot 11, and then the front end of the new lithium battery is aligned with the battery slot 11 and inserted into the battery slot 11. During this process, the connecting slider 12 can slide along the connecting slide groove 32, so that the lithium battery block 3 is stably inserted into the battery slot 11. Finally, the battery baffle 2 is manually pressed downwards to squeeze the pressing protrusion 31 at the lower end of the battery baffle 2. Since the rear side of the pressing protrusion 31 is inclined, the lithium battery block 3 can be gradually pushed forward during the downward movement of the battery baffle 2 until it is inserted into the battery slot 11. When the battery baffle 2 is pressed to the lowest position, the clamping protrusion 31 abuts against the battery baffle 2, which can effectively prevent the lithium battery block 3 from loosening, and the lithium battery can be quickly replaced. After the battery baffle 2 is pressed to the lowest position, the elastic force of the spring 5 can drive the slide 6 to move backward, so that the anti-loosening pin 62 is automatically inserted into the anti-loosening hole 22 to lock the battery baffle 2. When the battery baffle 2 needs to be pushed upward, the toggle handle 61 can be manually pushed forward first to drive the slide 6 to move forward, so that the anti-loosening pin 62 is removed from the anti-loosening hole 22, and the battery baffle 2 can be pushed upward to open.
