Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

A stabilizing sleeve 103 is sleeved on the surface of the positioning tooth bar 9. The rear side of the stabilizing sleeve 103 is fixedly connected to the front side of the support 1.

[0022] As a technical optimization solution of the present utility model, by setting the control mechanism 10, the positioning tooth bar 9 can be controlled to avoid loosening during the use of the positioning tooth bar 9, resulting in the positioning tooth bar 9 being unable to be tightly meshed and clamped with the tooth ring 8, thereby improving the positioning effect of the handwheel 7.

[0023] Reference Figure 3 , on the right side of the front side of the positioning tooth bar 9, a pull block 11 is fixedly connected, and the pull block 11 is located on the right side of the stabilizing sleeve 103.

[0024] As a technical optimization solution of the present utility model, by setting the pull block 11, it is convenient for the user to pull the positioning tooth bar 9 to move, avoiding the difficulty of pinching the positioning tooth bar 9 during the process of movement, resulting in the positioning tooth bar 9 being not easily pulled, and improving the control efficiency of the positioning tooth bar 9.

[0025] Reference Figure 3 , on the left side of the positioning tooth bar 9, a buffer pad 12 is fixedly connected, and the surface of the buffer pad 12 contacts the surface of the bracket 1.

[0026] As a technical optimization solution of the present utility model, by setting the buffer pad 12, the positioning tooth bar 9 can be protected to avoid the positioning tooth bar 9 hitting the bracket 1 during the movement process, preventing the positioning tooth bar 9 from being damaged, and improving the working safety of the positioning tooth bar 9.

[0027] Reference Figure 3 , on the top and bottom of the right side of the stabilizing sleeve 103, limiting plates 13 are fixedly connected, and the rear sides of the limiting plates 13 are fixedly connected to the front side of the bracket 1.

[0028] As a technical optimization solution of the present utility model, by setting the limiting plates 13, the sliding of the positioning tooth bar 9 can be stabilized to avoid the positioning tooth bar 9 shaking during the sliding movement process, resulting in the positioning tooth bar 9 loosening, and improving the sliding stability of the positioning tooth bar 9.

[0029] Reference Figure 3 , on the right side of the limiting plate 13, a limiting plate 14 is fixedly connected, and the limiting plate 14 is located on the right side of the positioning tooth bar 9.

[0030] As a technical optimization solution of the present utility model, by setting the limiting plate 14, the positioning tooth bar 9 can be limited to avoid excessive movement of the positioning tooth bar 9, and improve the working stability of the positioning tooth bar 9.

[0031] Reference Figure 2 , on the left side of the outer side of the limiting plate 13, reinforcing blocks 15 are fixedly connected, and the left sides of the reinforcing blocks 15 are fixedly connected to the right side of the stabilizing sleeve 103.

[0033] The working principle and usage process of the present utility model: During use, when the plastic cage needs to maintain a certain pressure for a period of time for detection, after rotating the handwheel 7, the positioning tooth bar 9 pulled by the right side is released, and the elastic force of the spring 101 pushes the positioning tooth bar 9 to move to the left. The positioning tooth bar 9 meshes and engages with the tooth ring 8, and the tooth ring 8 is fixed by the positioning tooth bar 9. The tooth ring 8 cannot rotate or move, and the handwheel 7 also cannot rotate or move accordingly. The cylindrical tooth bar 5 and the dynamometer 6 are fixed to maintain the downward pressure, thus having the advantage of accurately maintaining the same pressure value for detection.

[0034] In summary: For the compressive strength detection device produced by this plastic cage, through the combined use of the bracket 1, the detection plane 2, the support tooling 3, the cylinder 4, the cylindrical tooth bar 5, the dynamometer 6, the handwheel 7, the tooth ring 8, the positioning tooth bar 9, and the control mechanism 10, it solves the problem that when detecting the compressive strength of the plastic cage by rotating the handwheel to drive the cylindrical rack and the dynamometer to move downward, when it is necessary to maintain the pressure for a period of time for detection, the human arm cannot accurately maintain the same pressure, resulting in the plastic cage not being able to be continuously detected with the same pressure value by the compressive strength detection device, reducing the detection efficiency of the plastic cage.
