[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1 to 4 The utility model provides an embodiment: a fixture for punching holes in a computer bottom case, comprising a base 1, both sides of the upper end of the base 1 are fixedly connected to a support base 2, the interiors of the two opposite sides of the support bases 2 are movably connected to movable blocks 3, and the ends of the two movable blocks 3 close to each other extend through the outside of the support base 2, the bottom ends of the opposite sides of the two movable blocks 3 are fixedly connected to a supporting plate 4, and a movable groove 201 is opened on one side above the two movable blocks 3 and located inside the support base 2, and the interiors of the movable grooves 201 on both sides are slidably connected to connecting blocks 6.

[0022] The upper end of the connecting block 6 is rotatably connected to the threaded rod 5 through a rotating shaft. The thread of the threaded rod 5 extends through the top of the support seat 2. The front and rear inner walls of the movable groove 201 are provided with sliding grooves 202. The front and rear sides of the connecting block 6 are fixedly connected with sliders 7 that are slidably connected to the sliding grooves 202. The bottom end of the connecting block 6 close to the movable block 3 is set in an inclined surface. The upper end of the movable block 3 close to the connecting block 6 is provided with an inclined surface that fits with the movable block 3, and the connecting block 6 and the movable block 3 are in sliding contact through the inclined surface.

[0023] By placing the computer bottom case between the two support seats 2, and then rotating the threaded rod 5, the threaded rod 5 is threadedly rotated with the upper end of the support seat 2, and the connecting block 6 is pushed to move along the slide groove 202 toward one side of the movable block 3, and then the inclined surface of the connecting block 6 is matched with the inclined surface of the movable block 3, pushing the movable block 3 to move toward the side that passes through the support seat 2, and then the two movable blocks 3 are moved closer to each other on the opposite sides, and the support plate 4 is set, so that the computer bottom case is clamped according to the size of the computer bottom case. The side where the two movable blocks 3 are close to each other and the upper end of the support plate 4 are fixedly connected with a rubber pad 11. The setting of the rubber pad 11 can provide a certain protective effect on the clamping end of the computer bottom case.

[0024] The movable block 3 is away from the side of the support plate 4, and a connecting groove 203 is opened inside the support seat 2. The internal sliding connection of the connecting groove 203 is connected to the limiting plate 8. The side of the limiting plate 8 close to the movable block 3 is fixedly connected with a connecting rod 9 that penetrates the connecting groove 203 and is connected to the movable block 3. A spring 10 is fixedly connected between the side of the limiting plate 8 close to the movable block 3 and the inner wall of the connecting groove 203, and the spring 10 is wound around the outer surface of the connecting rod 9.

[0025] By moving the movable block 3 toward the side that passes through the support seat 2, the limit plate 8 and the connecting rod 9 are driven to move toward the side of the movable groove 201, thereby squeezing the spring 10 to compress and produce deformation. When the computer bottom case is processed, the threaded rod 5 is rotated in the opposite direction to make the connecting block 6 move away from the movable block 3. At this time, the spring 10 releases the elastic force and drives the movable block 3 and the support plate 4 to move toward the side close to the support seat 2, thereby resetting the movable block 3 and the support plate 4.

[0026] When the clamp for punching holes in a computer bottom case is used, the computer bottom case is placed between the two support seats 2, and then the threaded rod 5 is rotated so that the threaded rod 5 is threadedly rotated with the upper end of the support seat 2, and the connecting block 6 is pushed to move along the slide groove 202 toward one side of the movable block 3, and then the inclined surface of the connecting block 6 is engaged with the inclined surface of the movable block 3, pushing the movable block 3 to move toward the side that passes through the support seat 2, and driving the limit plate 8 and the connecting rod 9 to move toward the side of the movable groove 201, thereby squeezing the spring 10 to compress and deform, and then the opposite sides of the two movable blocks 3 are approached to each other, and the support plate 4 is set, so that the computer bottom case is clamped according to the size of the computer bottom case, and the rubber pad 11 is set to provide a certain protection for the clamping end of the computer bottom case. When the processing of the computer bottom case is completed, the threaded rod 5 is rotated in the opposite direction so that the connecting block 6 is away from the movable block 3. At this time, the spring 10 releases the elastic force and drives the movable block 3 and the support plate 4 to move toward the side close to the support seat 2, so that the movable block 3 and the support plate 4 are reset.
