[0027] Example:

[0028] See also Figure 1-2 , the utility model provides a technical solution:

[0029] A jaw crusher includes a fixed frame 1, a fixed jaw 2 is installed between the fixed frames 1, a movable jaw 3 is installed behind the fixed jaw 2, a shaft cylinder 4 is installed above the movable jaw 3, a rotating shaft 5 extends from both sides of the shaft cylinder 4, a flywheel 6 is installed at the other end of the rotating shaft 5, a fixed rod 8 is installed on the inner side of the fixed frame 1, an L-shaped connecting rod 9 is installed at the other end of the fixed rod 8, a support shaft 10 is installed at the other end of the connecting rod 9, a positioning plate 11 is installed below the support shaft 10, a fixed triangle 12 is installed below the outer side of the fixed frame 1, and a protective shell 7 is covered on the flywheel 6. The support shaft 10 and the fixed rod 8 are all connected to the connecting rod 9 by bearings. The installation principle, specific structure, and working method of the bearing connection are similar to those of the handle of a clothes drying rack, which belongs to the existing public technology, and its related technical features will not be repeated. In order to better fit the edge of the placement area, the cross-sectional shape of the positioning plate 11 is designed as a right-angled trapezoid. The edges where the inclined surface and the bottom surface of the positioning plate 11 intersect with the edges of the target placement position are fitted together, thereby achieving calibration of the placement position.

[0030] Specifically, the positioning plate 11 is installed in front of the fixed jaw 2 .

[0031] Specifically, the fixing triangle 12 is provided with a straight slot 15 .

[0032] Specifically, the flywheel 6 is covered with a protective shell 7, and the flywheel 6 and the protective shell 7 are detachably connected. The detachable connection method is a magnetic connection.

[0033] Specifically, the straight notches 15 are all designed with rounded corners, thereby increasing the contact area with the rope and reducing friction loss with the equipment.

[0034] Specifically, a magnetic block 13 is installed on the outside of the flywheel 6.

[0035] Specifically, a positioning magnetic block 14 is installed on the protective shell 7.

[0036] Working principle:

[0037] During transportation: the positioning magnet 14 on the protective shell 7 is attracted to the magnet 13 on the flywheel 6 so that the two are connected. In this way, the protective shell 7 protects the flywheel 6. The rope is fixed by passing it from the straight slot 15 on one side of the fixed frame 1 through the bottom of the transport vehicle and around the straight slot 15 on the other side.

[0038] Loading and unloading process: After lifting the equipment, rotate the connecting rod 9 to lower the positioning plate 11. When lowering the equipment, align the lower end of the positioning plate 11 with the edge of the ground or support where it is to be placed, and then slowly lower it, keeping the positioning plate 11 in contact with the edge of the area where it is to be placed.

[0039] After the equipment is lowered, the positioning plate 11 is returned to its original position by performing the reverse operation of the lowering process.

[0040] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed herein is not limited to technical solutions formed by a specific combination of the aforementioned technical features. It also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents, without departing from the concept of the utility model. For example, a technical solution formed by replacing the aforementioned features with (but not limited to) technical features with similar functions disclosed in this application.

[0041] Except for the technical features described in the specification, the remaining technical features are known technologies to those skilled in the art. In order to highlight the innovative features of the present invention, the remaining technical features will not be described here in detail.
