As a further description of the above technical solution:

The bottom of the second connecting column is fixedly connected with a bottom plate.

As a further description of the above technical solution:

A handle is fixedly connected to the side of the bottom plate, and four handles are symmetrically arranged.

As a further description of the above technical solution:

The two side edges of the connecting column are fixedly connected with a fixing plate, and the top of the fixing plate is fixedly connected with an inner connecting piece.

As a further description of the above technical solution:

The side edge of the fixing block is fixedly connected with an external connecting piece.

As a further description of the above technical solution:

The second sliding block is hemispherical.

As a further description of the above technical solution:

The first chute is connected to the second chute.

The utility model has the following beneficial effects:

In the utility model, the bottom plate is pushed to drive the connecting column 2 to slide upward, thereby driving the slider 2 to slide upward. The slider 2 slides relatively to the slider 1. The slider 2 pushes the slider 1 to the left and then continues to slide upward. After that, the slider 1 rebounds to the bottom of the slider 2 under the action of the spring to facilitate the position of the slider 2 to be clamped and fixed, so as to facilitate the installation and disassembly of the connecting piece.

DETAILED DESCRIPTION

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 in 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.

With reference to Fig. 1-Fig. 3, an embodiment of the utility model is provided: a fastener for convenient installation and removal, comprising a fixed block 1, wherein a slide groove 2 and a slide groove 3 are arranged inside the fixed block 1, a slider 8 is slidably connected in the slide groove 2, a connecting column 9 is fixedly connected at the bottom of the slider 8, a connecting column 10 is fixedly connected at the bottom of the connecting column 9, the connecting column 10 slides in the slide groove 2, a slider 4 is slidably connected in the slide groove 23, the slider 4 is trapezoidal, the slider 4 is fixedly connected to a connecting rod 5, a spring 7 is sleeved on the connecting rod 5, the spring 7 is located in the slide groove 23, the connecting rod 5 passes through and is rotatably connected in the fixed block 1, the connecting rod 5 passes through one end of the fixed block 1 and is fixedly connected to a limiting plate 6, and the limiting plate 6 can drive the connecting rod 5 and the slider 4 to slide in the slide groove 23.

A bottom plate 11 is fixedly connected to the bottom of the connecting column 10, a handle 12 is fixedly connected to the side of the bottom plate 11, four handles 12 are symmetrically arranged, a fixing plate 15 is fixedly connected to the side of the connecting column 10, an inner connecting piece 14 is fixedly connected to the top of the fixing plate 15, an outer connecting piece 13 is fixedly connected to the side of the fixing block 1, the sliding block 8 is hemispherical, and the sliding groove 2 and the sliding groove 3 are connected to facilitate the relative sliding of the sliding block 8 and the sliding block 4.

Working principle: Push the bottom plate 11 upward to drive the connecting column 2 10 to slide upward in the slide groove 2, drive the connecting column 1 9 and the slider 2 8 to slide upward in the slide groove 2. When the slider 2 8 moves to be level with the slider 1 4, it slides relative to the slider 1 4 to push the slider 1 4 to the left, so that the slider 1 4 slides to the left in the slide groove 2 3 and the spring 7 is compressed. When the slider 2 8 continues to slide upward to be higher than the slider 1 4, the slider 1 4 drives the slider 1 4 to slide to the right under the action of the rebound force of the spring 7 and returns to its original position, located at the bottom of the slider 2 8, so as to clamp and fix the current position of the slider 2 8, thereby fastening the inner connecting member 14 and the outer connecting member 13. Conversely, pull the limit plate 6 to the left to drive the slider 1 4 to move to the left, so as to facilitate the extraction of the connecting column 2 10, the connecting column 1 9 and the slider 2 8 from the slide groove 2, so as to facilitate the disassembly of the connecting member.
